Social Media Welcome To Reality Online | Pat Selby Coaching Blog

Although other individuals might feel you are basically enjoying the a number of aspects of social networking, the truth of your interest may possibly most likely be tinged with a enterprise concentrate.

What that doesnt imply is that you post merely to leave a traceab?

The use of social media encompasses a broad range of on the web media varieties. Even though some could only assume of a social network like MySpace there are in fact numerous social media formats that include substantial advertising and marketing potential for on the internet company.

Even though others may possibly feel you are basically enjoying the several elements of social networking, the truth of your interest might most likely be tinged with a organization focus.

What that doesnt imply is that you post basically to leave a traceable link back to your organization website. Those who go to any social media web site see via posts that are overtly geared toward marketing and advertising. In numerous situations social media customers view this as spam even if the social network owners do not. In the finish, you can lose credibility of you dont function as a meaningful contributor in a social media atmosphere.

Social media can be presented in a lot of various forms. Lets take a peak at a couple of of them.

YouTube and other comparable video websites These videos can be funny, severe, off the cuff and often political in nature. You can show your business in a humorous light and enable people to be curious about you and your company.

MySpace and other social networks This form of social media is common simply because it draws with each other a number of components of social marketing and tends to make them accessible to the masses of folks that might view social networking as an on the internet version of reality television.

Blogs This is a form of social media if only because it does permit interactive exchanges in between the blogger and the reader.

Forums This can allow you to have an person voice willing to talk about subjects of interest to the majority. As with all social media you can give a link to your web site. If you are viewed as a trusted source you will likely find forum members following you to your site to discover more.

Podcasting This is an audio stream that can enable a visitor to hear a private message from you. This can have a pronounced impact in social advertising.

This isnt an exhaustive list, but it does offer something for you to take into account as an addition to other advertising and marketing tactics you might have in spot. Social media makes it possible for you to take your message to the people and have enjoyable while you share your message.

I cant pressure adequate how important it is to be real. The entire Web community has a low tolerance for supposed spam so make certain you dont use social media as merely an additional type of on the internet advertising.

It's a bird, it's plane...no, it's a drone

WASHINGTON (AP) ? It's a good bet that in the not-so-distant future aerial drones will be part of Americans' everyday lives, performing countless useful functions.

A far cry from the killing machines whose missiles incinerate terrorists, these generally small, unmanned aircraft will help farmers more precisely apply water and pesticides to crops, saving money and reducing environmental impacts. They'll help police departments find missing people, reconstruct traffic accidents and act as lookouts for SWAT teams. They'll alert authorities to people stranded on rooftops by hurricanes and monitor evacuation flows.

Real estate agents will use them to film videos of properties and surrounding neighborhoods. States will use them to inspect bridges, roads and dams. Oil companies will use them to monitor pipelines, while power companies use them to monitor transmission lines.

With military budgets shrinking, drone makers have been counting on the civilian market to spur the industry's growth. But there's an ironic threat to that hope: Success on the battlefield may contain the seeds of trouble for the more benign uses of drones at home.

The civilian unmanned aircraft industry worries that it will be grounded before it can really take off because of fear among the public that the technology will be misused. Also problematic is a delay in the issuance of government safety regulations that are needed before drones can gain broad access to U.S. skies.

Some companies that make drones or supply support equipment and services say the uncertainty has caused them to put U.S. expansion plans on hold, and they are looking overseas for new markets.

"Our lack of success in educating the public about unmanned aircraft is coming back to bite us," said Robert Fitzgerald, CEO of The BOSH Group of Newport News, Va., which provides support services to drone users.

"The U.S. has been at the lead of this technology a long time," he said. "If our government holds back this technology, there's the freedom to move elsewhere ... and all of a sudden these things will be flying everywhere else and competing with us."

Since January, drone-related legislation has been introduced in more than 30 states, largely in response to privacy concerns. Many of the bills are focused on preventing police from using drones for broad public surveillance, as well as targeting individuals for surveillance without sufficient grounds to believe they were involved in crimes.

Law enforcement is expected to be one of the bigger initial markets for civilian drones. Last month, the FBI used drones to maintain continuous surveillance of a bunker in Alabama where a 5-year-old boy was being held hostage.

In Virginia, the state General Assembly passed a bill that would place a two-year moratorium on the use of drones by state and local law enforcement. The measure is supported by groups as varied as the American Civil Liberties Union on the left and the Virginia Tea Party Patriots Federation on the right.

Gov. Bob McDonnell is proposing amendments that would retain the broad ban on spy drones but allow specific exemptions when lives are in danger, such as for search-and rescue operations. The legislature reconvenes on April 3 to consider the amendments.

"Any legislation that restricts the use of this kind of capability to serve the public is putting the public at risk," said Steve Gitlin, vice president of AeroVironment, a leading maker of smaller drones, including some no bigger than a hummingbird

Seattle abandoned its drone program after community protests in February. The city's police department had purchased two drones through a federal grant without consulting the city council.

Drones "clearly have so much potential for saving lives, and it's a darn shame we're having to go through this right now," said Stephen Ingley, executive director of the Airborne Law Enforcement Association. "It's frustrating."

In some states economic concerns have trumped public unease. In Oklahoma, an anti-drone bill was shelved at the request of Republican Gov. Mary Fallin, who was concerned it might hinder growth of the state's drone industry. The North Dakota state Senate killed a drone bill in part because of concern that it might impede the state's chances of being selected by the Federal Aviation Administration as one of six national drone test sites, which could generate local jobs.

A bill that would have limited the ability of state and local governments to use drones died in the Washington legislature. The measure was opposed by The Boeing Co., which employs more than 80,000 workers in the state and which has a subsidiary, Insitu, that's a leading military drone manufacturer.

Although the Supreme Court has not dealt directly with drones, it has OK'd aerial surveillance without warrants in drug cases in which officers in a plane or helicopter spotted marijuana plants growing on a suspect's property. But in a case involving the use of ground-based equipment, the court said police generally need a warrant before using a thermal imaging device to detect hot spots in a home that might indicate that marijuana plants are being grown there.

In Congress, Rep. Ed Markey, D-Mass., co-chairman of the House's privacy caucus, has introduced a bill that prohibits the Federal Aviation Administration from issuing drone licenses unless the applicant provides a statement explaining who will operate the drone, where it will be flown, what kind of data will be collected, how the data will be used, whether the information will be sold to third parties and the period for which the information will be retained.

Sentiment for curbing domestic drone use has brought the left and right together perhaps more than any other recent issue. "The thought of government drones buzzing overhead and constantly monitoring the activities of law-abiding citizens runs contrary to the notion of what it means to live in a free society," Sen. Charles Grassley, R-Iowa, said at a recent hearing of the Senate Judiciary Committee.

Privacy advocates acknowledge the many good uses of drones. In Mesa County, Colo., for example, an annual landfill survey using manned aircraft cost about $10,000. The county recently performed the same survey using a drone for about $200.

But drones' virtues can also make them dangerous, they say. Their low cost and ease of use may encourage police and others to conduct the kind of continuous or intrusive surveillance that might otherwise be impractical. Drones can be equipped with high-powered cameras and listening devices, and infrared cameras that can see people in the dark.

"High-rise buildings, security fences or even the walls of a building are not barriers to increasingly common drone technology," Amie Stepanovich, director of the Electronic Privacy Information Council's surveillance project, told the Senate panel.

Civilian drone use is limited to government agencies and public universities that have received a few hundred permits from the FAA. A law passed by Congress last year requires the FAA to open U.S. skies to widespread drone flights by 2015, but the agency is behind schedule and it's doubtful it will meet that deadline. Lawmakers and industry officials have complained for years about the FAA's slow progress.

The FAA estimates that within five years of gaining broader access about 7,500 civilian drones will be in use.

Sen. Rand Paul, R-Ky., recently drew attention to the domestic use of drones when he staged a Senate filibuster, demanding to know whether the president has authority to use weaponized drones to kill Americans on American soil. The White House said no, if the person isn't engaged in combat. But industry officials worry that the episode could temporarily set back civilian drone use.

"The opposition has become very loud," said Gitlin of AeroVironment, "but we are confident that over time the benefits of these solutions (drones) are going to far outweigh the concerns, and they'll become part of normal life in the future."

Shroud of Turin goes on display amid new research

Archbishop of Turin Cesare Nosiglia, center, kneels in front of the Shroud of Turin that went on display for a special TV appearance Saturday, March 30, 2013. The Shroud went on display amid new research disputing claims it's a medieval fake and purporting to date the linen some say was Jesus' burial cloth to around the time of his death. Pope Francis sent a special video message to the event in Turin's cathedral, but made no claim that the image on the shroud of a man with wounds similar to those suffered by Christ was really that of Jesus. He called the cloth an "icon," not a relic ? an important distinction. "This image, impressed upon the cloth, speaks to our heart and moves us to climb the hill of Calvary, to look upon the wood of the Cross, and to immerse ourselves in the eloquent silence of love," he said.

VATICAN CITY (AP) ? The Shroud of Turin went on display for a special TV appearance Saturday amid new research disputing claims it's a medieval fake and purporting to date the linen some say was Jesus' burial cloth to around the time of his death.

Pope Francis sent a special video message to the event in Turin's cathedral, but made no claim that the image on the shroud of a man with wounds similar to those suffered by Christ was really that of Jesus. He called the cloth an "icon," not a relic ? an important distinction.

"This image, impressed upon the cloth, speaks to our heart and moves us to climb the hill of Calvary, to look upon the wood of the Cross, and to immerse ourselves in the eloquent silence of love," he said.

"This disfigured face resembles all those faces of men and women marred by a life which does not respect their dignity, by war and violence which afflict the weakest," he said. "And yet, at the same time, the face in the Shroud conveys a great peace; this tortured body expresses a sovereign majesty."

Many experts stand by carbon-dating of scraps of the cloth that date it to the 13th or 14th century. However, some have suggested the dating results might have been skewed by contamination and have called for a larger sample to be analyzed.

The Vatican has tiptoed around just what the cloth is, calling it a powerful symbol of Christ's suffering while making no claim to its authenticity.

The 14-foot-long, 3.5-foot-wide (4.3-meter-long, 1 meter-wide) cloth is kept in a bulletproof, climate-controlled case in Turin's cathedral, but is only rarely open to the public. The last time was in 2010 when more than 2 million people lined up to pray before it and then-Pope Benedict XVI visited.

The latest display coincided with Holy Saturday, when Catholics mark the period between Christ's crucifixion on Good Friday and his resurrection on Easter Sunday. A few hundred people, many in wheelchairs, were invited inside the cathedral for the service, which was presided over by Turin's archbishop. It was only the second time the shroud has gone on display specifically for a TV audience; the first was in 1973 at the request of Pope Paul VI, the Vatican said.

The display also coincided with the release of a book based on new scientific tests on the shroud that researchers say date the cloth to the 1st century.

The research in "The Mystery of the Shroud," by Giulio Fanti of the University of Padua and journalist Saverio Gaeta, is based on chemical and mechanical tests on fibers of material extracted for the carbon-dating research. An article with the findings is expected to be submitted for peer-review, news reports say.

Protective prion keeps yeast cells from going it alone

Friday, March 29, 2013

Most commonly associated with such maladies as "mad cow disease" and Creutzfeldt-Jakob disease, prions are increasingly recognized for their ability to induce potentially beneficial traits in a variety of organisms, yeast chief among them.

Now a team of scientists has added markedly to the job description of prions as agents of change, identifying a prion capable of triggering a transition in yeast from its conventional single-celled form to a cooperative, multicellular structure. This change, which appears to improve yeast's chances for survival in the face of hostile environmental conditions, is an epigenetic phenomenon?a heritable alteration brought about without any change to the organism's underlying genome.

This latest finding, reported in the March 28 issue of the journal Cell, has its origins in work begun several years ago in the lab of Whitehead Institute Member Susan Lindquist. In 2009, Randal Halfmann, then a graduate student in Lindquist's lab, identified dozens of proteins in yeast that have the ability to form prions. That research greatly expanded the known universe of prion elements in yeast, but it failed to answer a key question: What function, if any, do these prions actually have?

In search of an answer, Halfmann, now a fellow the University of Texas Southwestern Medical Center, and colleagues in the Lindquist lab attempted to exploit the fact that several of the prion-forming proteins they had identified acted to modify transcription of yeast genes. It stood to reason that if they could identify which genes were being regulated, they might be able to determine the prions' function.

"We looked at the five transcriptional regulators that are known to be prions in yeast, and we found that in fact, only one gene in the entire yeast genome was regulated by all five transcription factors," says Halfmann.

That gene, as it turns out, was FLO11, a key player in multicellularity in yeast. Indeed changes in FLO11 expression have been shown to act as a toggle, switching yeast from spherical to filamentous form. Halfmann notes that FLO11, which has been shown to be regulated by epigenetic elements, is also highly responsive to environmental stress. Knowing that the prion form of a protein is essentially a misfolded form of that protein, and that stressful conditions increase the frequency of protein misfolding and prion formation, the scientists began to consider the possibility that the prions themselves might be among the epigenetic switches influencing the activity of FLO11.

The group focused on one transcription factor known as mot3, finding that yeast cells containing the prion form of this factor, [MOT3+], acquired a variety of multicellular growth forms known to require FLO11 expression. This was a clear indication that prion formation was causing the differentiation of the cells and their subsequent cooperation. But what about the stress aspect of the hypothesis?

By testing yeast cells against a variety of stressors, the scientists discovered that exposure to a concentration of ethanol akin to that occurring naturally during fermentation increased [MOT3+] formation by a factor of 10.They also found that as the cells exposed to ethanol shifted their metabolism to burn surrounding oxygen through respiration, the prions reverted to their non-prion conformation, [mot3-], and the yeast returned to the unicellular state. In essence, prion formation drove a shift to multicellularity, helping the yeast to ride out the ethanol storm.

"What we have in the end is two sequential environmental changes that are turning on a heritable epigenetic element and then turning it off," says Halfmann. "And between those two changes, the prion is causing the cells to acquire a multicellular growth form that we think is actually important for their survival."

Lindquist, who is also a Howard Hughes Medical Institute investigator, has long argued that prions have played a vital role in yeast evolution and has amassed a body of strong supporting evidence.

"We see them as part of a bet-hedging strategy that allows the yeast to alter their biological properties quickly when their environments turn unfavorable," Lindquist says. She also theorizes that prions may play such roles beyond yeast, and her lab intends to take similar approaches in the hunt for prions and prion-like mechanisms that are potentially beneficial in other organisms.

For Lindquist lab postdoctoral scientist Alex Lancaster, who is also an author of the new Cell paper, these latest findings hint at a potentially novel approach to understanding basic mechanisms underlying the complexities of human diseases, including cancer, whose hallmarks include protein misfolding, epigenetic alterations, metabolic aberrations, and myriad changes in cell state, type, and function. Lancaster likens the opportunity to that of opening a black box.

"It's exciting to think that this could become another tool in the toolbox in the study of multicellularity," Lancaster says. "We know that some tumors are a heterogeneous population of cells and we know that tumor cells can evolve within in their environments to help ensure their own survival. This system could help us further understand the role of epigenetic inheritance within tumors and how it might be influencing cell-cell interactions and even affecting the effectiveness of drug therapies."

Do You Own a Hybrid? Would You Buy a Hybrid? - Wakefield, MA ...

Hybrid cars have come a long way since the Honda Insight became the?first hybrid for sale in North America in late 1999. For one, the styling has gone from futuristic insect to more traditional looks.

And while once the sight of a Prius rolling by would turn heads, hybrids seem ubiqutious now. (The more traditional looking models also don't turn as many heads.)

There are the well-known pros to hybrids, starting with cutting down on trips to the gas station. The miles per gallon (or miles per gallon equivalent, to be exact) these cars get is the first specification that jumps out at most people, and what many customers are looking for when shopping for a hybrid.

For city-dwellers, the fuel economy of hybrids is often better for city driving than for highway driving, flipping the script on traditional gas-only vehicles. And whether you're driving a hybrid to spare the air from pollutants or not, they generally have great resale value.

On the other hand, there are cons, starting with the upfront cost. While you won't spend as much on gasoline while driving a hybrid, they are more expensive off the lot than traditional gas-only vehicles.

Improvements have been made when it comes to power and performance, but many hybrids still can't match gas-only vehicles. And those batteries can end up taking up space that would otherwise be used for seating or storage, so if you're lugging a lot of cargo or kids around, a trip to the grocery store might not yield as big a bounty.

And perhaps a reflection on the economy, despite gas prices still well above $3 a gallon, a study completed last year said that only 35 percent of hybrid owners choose to purchase a hybrid again.

Do you own a hybrid car now? Would you purchase one again when you're shopping for a new car? If you don't own a hybrid, would you consider purchasing one for your next car? Tell us your thoughts in the comments.

U.S. Poet Laureate Philip Levine ? A lifetime of giving a thundering ...

U.S. Poet Laureate, Philip Levine, at a recent visit to the University of Texas at El Paso. (David A. Reyes/Borderzine.com)

EL PASO ? Poet Laureate Philip Levine, still as fit and funny at age 85 as he was as a young man working the night shift at a car factory, shared his special brand of earthy, poignant and insightful poetry ? and a sizable measure of good humored repartee ?? with over 1000 fans at UTEP recently.

The poet of the working class, who was born in Detroit to poor Russian Jewish immigrant parents, began writing professionally in the early 1950?s and has been giving ?a voice to the voiceless? ever since. His message and poetry resonated with his El Paso audience in a city that is predominately Hispanic and working class.

Asked by Sociologist Gina Nu?ez what he thinks of the billions spent by the U.S. government erecting walls along the 2000-mile border, Levine responded: ?The worst walls are the ones we can?t see because we are erecting interior walls. You say they?re dividing families. They?re also dividing ethnic groups. They?re dividing us from ourselves by creating aspects of ourselves we can?t welcome into the total soul of ourselves.?

Equating the border fence to the Berlin Wall, he added: ?It will fall. It will fall, and we will see. We will reflect later on. By we, I mean the people who care and people who study, and eminent historians, of what a fiasco it was.?

During an evening lecture to a packed campus lecture hall, the poet demonstrated his empathy toward the immigrant experience and the political hardship caused by divided borders. ?We have a long way to go to become the country we say we are,? he quipped. ?Will we do it? Don?t ask me, kid. I sure hope so, but I know it?s not going to happen in my lifetime. But that?s not saying much. I?m 85. Who knows how long it?s going to go.?

In her introduction to Levine?s lecture, Creative Writing Professor Sasha Pimentel, said:

?[His poetry] demands in an incisive and thundering voice that we listen to? the voices of those who without Levine?s throat would not otherwise been given a voice,? said Pimentel, who helped organize Levine?s visit to UTEP and is a well-regarded published poet in her own right.

A former Philip Levine fellow, Pimentel said she treasures Levine?s ?utter compassion? to write about ?people we ourselves in El Paso know and understand. About men in overalls and a woman in a black smock at the polishing wheel, about feet and rubber boots, and children, their heads bowed low in a classroom in Fourth grade. We could recognize our mothers and our brothers in the work of Philip Levine.?

The crowd cheered inside the UGLC auditorium when the 2010-11 Poet Laureate walked to the podium and began to speak about the different chapters of his life, his early decision to become a writer and his dedication to giving voice to the lives and concerns of everyday Americans.

One moving poem, ?My Father with Cigarette Twelve Years Before the Nazis Could Break His Heart,? dealt with Hitler era Germany, and ended with these lines:

that the villages were gone. The truth is?
if there is a truth? I remember the room,
I remember the flame, the blue smoke,
how bright and slippery were the secret coins,
how David Copperfield doubted his own name,
how sweet the stars seemed, peeping and blinking,
how close the moon, how utterly silent the piano.

After the reading, Communication Professor Andrew Kennis asked him about the differences and similarities between journalism, poetry, and fiction.

Without missing a beat the poet responded that much of journalism today is fiction. ?The problem is it isn?t written as well,? he said to laughs from the audience. ?As for poetry, it?s a different discipline. Of course it draws from the same source: events, objects and people in the actual world, but it uses them in different ways. It is not journalistic because it feels no obligation to the facts.?

He also had some words of advice for aspiring writers: ?Do the best you can, and be patient?because it doesn?t happen overnight.? The 18th U.S. Poet Laureate said he was once asked what advice he had for a 25-year-old wannabe writer. ?I thought about it a long time and the answer was very simple: take better care of your teeth.?

Earlier in the day, Levine spoke to a group of 20 Liberal Arts Honors students in a classroom.? The students are enrolled in a special honors class, taught by Nu?ez and journalist Zita Arocha, which combines ethnography and journalism to study issues of social class on the U.S. Mexico border.

When one student asked his views about Anarchism during the Spanish Civil war, Levine addressed reactions to unjust political structures and discussed his own political frustrations.

?I am in part a contributing member to the American Society, which I recognize has many very ugly aspects about which I can do almost nothing.? In his youth, Levine said, he thought he could ?do things.?

?That was part of the optimism of the 60?s that there would be this significant change in American attitudes and American culture,? he said. ?And that was part of the glory of the 60?s. It was also part of the childishness; the confidence that there would be these changes.?

During his one-year appointment as Poet Laureate he said he had a chance to voice his concerns and speak out about government policies and decisions he disagreed with.

?I would get a call from the Library of Congress asking if I would just tone it down a bit. And every Monday I said I?ll do my best to tone it down,? he said. ?And I did, which was that I did nothing. I said what I wanted to say. I was only going to have this position for a short while so why not get out there and insult people.?

When he responded to questions from the class, Levine?s sharply honed extemporaneous wit made everyone laugh several times. When Arocha used an iPad to snap his picture a relaxed Levine chimed: ?Are you trying to take my picture?

?I am,? Arocha said.

?You haven?t gotten my permission.?

?I?m a journalist; we don?t need permission,? said Arocha, smiling. ?I?m actually tweeting some of what you?re saying. You know what that is right??

?Oh, yeah. I don?t do it, but I know what it is. It?s kind of like sex, right??

The room exploded in laughter at the quintessentially comic Levine response.

One student asked what made him leave his night shift job at the Gear and Axle automobile factory and use his savings to go to college and study creative writing at age 25 at the University of Iowa.

?To answer in all honesty, I would say my divorce.?

He noted that during his second semester at Iowa he ran out of money and couldn?t register for classes but sat in anyway on a class taught by renowned poet John Barryman. ?He was the greatest teacher I ever had. I never needed another teacher,? Levine said.

?You can be anything and be a great poet. It?s not politically correct. That is the wisdom of an old man,? concluded the energized Levine, donning a green baseball cap to avoid ?looking like the head of a corporation,? as students and teachers gathered around him for a picture.

As Pimentel began snapping pictures, she said: ?Okay, everyone squeeze in. After the conversation about sex, you guys shouldn?t be shy.?

Before departing, the ever-humble Levine offered one last quip: ?I would love to thank all of those who were responsible for bringing me here? They?ve worked me like mad, but it?s all right.?

Don Payne, 'Simpsons' co-executive producer and 'Thor' screenwriter, dies of cancer

By Greg Gilman

LOS ANGELES (TheWrap.com) - Don Payne, a co-executive producer of "The Simpsons" and "Thor" screenwriter, died in Los Angeles on Tuesday after battling cancer. He was 48.

The University of California, Los Angeles graduate won four primetime Emmys with "The Simpsons" since joining the Fox show's writing staff in 1998. Payne wrote 16 episodes, including "Fraudcast News," which earned him the 2005 Writers Guild Paul Selvin Award.

"Don was a wonderful writer and an even more wonderful man," said "Simpsons" showrunner Al Jean in a statement. "He was beloved in the 'Simpsons' community and his untimely passing is terrible news to us all. I know he is up with Thor now looking down at us and smiling."

During his tenure at "The Simpsons," Payne also branched out into screenwriting with 2006's "My Super Ex-Girlfriend," followed by 2007's "Fantastic 4: Rise of the Silver Surfer." Payne also wrote a draft of "Thor" for Marvel, before working on the sequel, "Thor: The Dark World."

"Maximum Ride," Payne's most recent writing gig, is an adaptation of a James Patterson novel about genetically-engineered children with wings taking flight across the country to discover their origins. The film doesn't yet have a release date.

Payne had two episodes of "The Simpsons" in production at the time of his death. Both are scheduled to air during the show's Season 25, including this year's Christmas special, "White Christmas Blues."

Payne is survived by his wife and three children.

6 Things Your Dreams Can Tell You About Your Health

The last time you woke up from a dream, you may have wondered why exactly you were back at high school, standing in front of your locker, unable for the life of you to remember the combination. When it comes to dream meanings, most of us expect those visions to reveal mental health truths, whether they be feelings about a life event, relationship or simply a memory.

But after recent research highlighted a potential link between acting out dreams and a common form of dementia, perhaps there is more we can learn about our physical health from our dreams.

The research, presented at the annual meeting of the American Academy of Neurology, found that men with a risk factor for dementia with Lewy bodies, in addition to what's known as REM sleep behavior disorder, are five times more likely to have this type of dementia. The same sleep disorder has also been linked to Parkinson's disease, symptoms of which are similar to those of dementia with Lewy bodies.

Anecdotally, some say that dreams have predicted cancer, alerted a patient to tuberculosis or even warned of a heart attack. There's little -- if any -- scientific evidence that certain dream symbols can be interpreted to predict any real health symptoms. But there is some concrete proof that more dreams, stranger dreams or recurring dreams could have important meaning when it comes to your physical health.

You Have A Fever
If you're the type to ignore the signs that you're under the weather, maybe a freaky nightmare will prove the point. Being sick can trigger nightmares, according to the Mayo Clinic, especially if your illness is accompanied by a fever. If you weren't paying attention to what your body was trying to tell you before, the morning after that weird nightmare is the time to tune in!

Stress Is Getting The Best Of You
You might also be ignoring signs that you're more than a little stressed out. When we ignore what's taxing us, those stressors can follow us to bed. Sometimes, stress can manifest itself as common dream themes like missing a plane or an oncoming tidal wave, according to DoctorOz.com. Other times, a particularly bizarre dream might help you realize it's time to slow down. Some say that stress dreams might actually be helpful if they reveal what's truly bothering you and point to why you're feeling that way.

Your Blood Sugar Could Be Low
If people with diabetes experience a serious dip in blood sugar, one possible symptom can be bad dreams and nightmares, according to WebMD. Taking too much insulin or certain medications can cause this drop, called hypoglycemia. Of course, most people with diabetes will learn to recognize early symptoms of low blood sugar before nightmares point out the problem. But hypoglycemia can occur during sleep.

Pregnant? Good News!
Many a mother can attest to dreaming more while pregnant. Over those nine months, dreams seem to increase in general, but strange or vivid dreams can become particularly common. Although more -- and scarier -- dreams aren't necessarily pleasant, a mom-to-be with strange or upsetting dreams might actually be in luck: An Israeli study of 166 pregnant women found that the more harrowing dreams a woman had, the less likely she was to develop postpartum depression. And an Italian study of 290 women linked more dreams (and more upsetting dreams) with shorter labor times.

It May Be Time To Consult A Mental Health Specialist
If stress and anxiety can cause such strange and often upsetting dreams, it should come as no surprise that more serious mental health conditions can similarly interrupt your sleep. Bipolar disorder is known to cause vivid or bizarre dreams in some people, according to WebMD. And a study of Vietnam veterans found that 52 percent of combat vets with post traumatic stress disorder (PTSD) had nightmares fairly often, compared to only 3 percent of civilians, according to the U.S. Department Of Veterans Affairs. If you find yourself experiencing nightmares or very vivid dreams frequently, considering discussing your sleep with your doctor. Seeking treatment for both of these conditions can improve the quality of your sleep.

U.S. rapper Gucci Mane jailed for alleged assault

ATLANTA (Reuters) - Rapper Gucci Mane was jailed in Georgia on Wednesday for allegedly hitting a fan in the head with a champagne bottle at an Atlanta nightclub earlier this month.

Mane, whose real name is Radric Davis, turned himself in to authorities late on Tuesday, according to Fulton County Sheriff's Office records.

Mane, 33, faces an aggravated assault charge after causing a "severe laceration" to the man whom he hit with a champagne bottle on March 16, according to a police report. The fan had approached Mane and tried to strike up a conversation, police said. Mane left the nightclub before police arrived.

A magistrate judge denied bond for Mane at his first court appearance on Wednesday, sheriff's spokeswoman Tracy Flanagan said.

Mane did not enter a plea. His next hearing will be on April 10, Flanagan said.

Mane's attorney, Drew Findling, told Reuters he would appeal the denial of bond to a higher court. He said six witnesses interviewed by his office about what he described as a melee at the club did not pin blame on the rapper.

"None of them said Gucci had anything to do with it," Findling said.

The incident is the latest in a long string of legal troubles for the rapper, who has appeared in remixes with the Black Eyed Peas and Usher.

In 2001, Mane was arrested for cocaine possession and spent 90 days in jail. He served a six-month prison term in 2005 for assault, and in 2009 was imprisoned for a year for violating probation in that case.

A Georgia judge sentenced Mane to six months in jail in 2011 after he admitted to pushing a woman out of his car.

Where did Saturn's rings come from? Mystery gets a new clue.

Saturn's rings are one of the most recognized features of the solar system, but scientists don't know how they got there. New data suggest they're older than some theories suggested.

By Pete Spotts,?Staff writer / March 28, 2013

This image of Saturn and its rings was captured by the Cassini spacecraft.

Space Science Institute/JPL-Caltech/NASA/Reuters

New evidence from the US-European Cassini mission to Saturn suggests a very early birth for ices in Saturn?s spectacular system of rings and moonlets, dating back to shortly after the planet itself formed.

Skip to next paragraph

The results deepen a mystery that has bedeviled Saturn watchers since Galileo first spotted what later would be interpreted as rings in 1610: How did the rings form? And, more recently, what sustains the ring system?

?No one actually knows why the rings can survive for 4.5 billion years,? says Scott Kenyon, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. ?At the moment, we don?t have a good model? that explains this longevity.

The apparently implausible life span of the ring system has led some researchers to propose that the system didn?t form shortly after the planet did.?

Instead, it might have formed perhaps 100 million years ago. The raw material for the rings and moonlets could have come from the debris spawned by a collision between close-in moons, or between a close-in moon and a comet.

But the recent-ring scenario has had a troubled existence.?

In 2007, for example, scientists reported evidence from Cassini?s Ultraviolet Imaging Spectrometer indicating that the rings had significant age differences and that the material in the rings was constantly being recycled as moonlets collided. Some of the debris later would form into new moonlets.?

That evidence didn?t support a single, recent violent encounter between objects as a source of material for the ring system.

Now, researchers using another of Cassini?s instruments, the Visual and Infrared Mapping Spectrometer (VIMS), have uncovered further evidence for this recycling as they have mapped changes in the composition of the ring material and moonlets that form a 40,800-mile-wide band around the planet.

Perhaps more important, Cassini has uncovered far more water ice in the system than comets could deliver.

The system ?is very ice rich,? says Bonnie Buratti, a researcher at NASA?s Jet Propulsion Laboratory in Pasadena, Calif., and a member of the VIMS team.

To Dr. Kenyon, the results showing ices throughout the system speak to a primeval origin.

?All of the stuff inside the really major moons is composed of the same stuff as the major moons,? he says. ?That?s really nice to know because that tells you the rings are 4.5 billion years old.?

But that still leaves the question of longevity.

Left to their own devices, the moonlets would migrate ever farther from Saturn, leaving the ring system within perhaps 100 million years or so.

Cassini has revealed that moonlets form from material that accretes at the outer edges of the rings, explains Phillip Nicholson, an astronomer at Cornell University in Ithaca, N.Y., and a member of the team reporting the VIMS results this week in the Astrophysical Journal.

One possible solution to the conundrum would be to give the ring system more initial mass than researchers have presumed.

Modeling work by Robin Canup, a scientist at the Southwest Research Institute in Boulder, Colo., has suggested that some 2 million to 5 million years after it formed, Saturn had ? and devoured ? several moons the size of Titan, the planet?s largest existing satellite. But these other Titan-scale moons orbited too close to the planet to survive.

As they were drawn to their doom, the tidal forces Saturn exerted on the last victim stripped a thick icy crust and mantle from the moon?s rocky core. The ice broke up to begin forming a ring, while the core continued its death spiral into the planet.

Such a ring would have hosted far more mass than today?s rings do, according to the study, published in 2010.

The ring in the modeling also mimicked observed ring behaviors: losing mass over time while forming moons at the outer edges of the ring, for instance. The moons it formed were similar in mass to the icy moons out to and including Tethys.

The hope is that a knowledge of the composition of ring material and the moonlets in Saturn?s ring system will shed light on the ring-forming process.

Cassini launched as the Cassini-Huygens mission in October 1997 and began orbiting Saturn in July 2004. The following December, the spacecraft released the European Space Agency?s Huygens probe toward a successful landing on Saturn?s moon Titan. Since then, the orbiter has been touring the planet?s moons and rings, giving researchers an unprecedented look at the Saturn system.

PFT: 19 NFL teams owned by billionaires

Manti TeoAP

As the calendar approaches April, the pre-draft spin cycle will soon hit overdrive.

The rules are simple.? Teams that don?t like a player will say good things about him, hoping that someone with a higher pick will take the player, which will push a more viable prospect down the board.? Teams that like a player will say bad things about him, hoping that he?ll still be there when the team makes its pick.

It?s important to keep those rules in mind when considering any off-the-record assessments of players by scouts and coaches who, depending on the teams for which they work, may be hoping to influence what other teams will or won?t do.

Jason Cole of Yahoo! Sports spoke to scouts and coaches from multiple unnamed teams who attended the Monday Pro Day workout of Notre Dame linebacker Manti Te?o.? And none of those folks regard Te?o as a first-round pick.

?Nice player, but not worth a first-round pick.? Not in my view,? said an unnamed ?AFC personnel man.?

?He?s not a star,? an AFC head coach said.? ?If I?m taking a linebacker in the first round, I want a guy who can change my defense.? Trust me, I?ve been wrong about linebackers before, but this guy doesn?t fit the bill of what I spend a high pick on.?

?[H]e?s not good enough in my view,? an NFC defensive coordinator said.

We don?t doubt for a second that these sources said what Cole says they said.? But without knowing which team they work for, it?s impossible to know whether they really mean it.

It?s a common reality of the pre-draft process.? Scouts and coaches knock certain players, possibly because the scouts and coaches believe what they?re saying ? and possibly because they have an agenda.? When it comes to the draft, everyone has an agenda.? When it comes to the strategy-driven NFL, everyone periodically (or more often) tells untruths to advance their agenda.

We?re not saying it?s right or it?s wrong.? That?s just the way it is.? But that makes it impossible to put much stock in the things being said by unnamed sources who may be secretly hoping that the player they?re knocking slides into their laps.

Buffer for iPhone lets you track Facebook and Twitter analytics, schedule posts, and more

Track Facebook and Twitter analytics, schedule posts, and more with Buffer for iPhone

Buffer is a service that allows you to monitor and post to your social networks such as Facebook, Twitter, LinkedIn, and App.net. This includes queueing up posts to be shared at a later time or date, monitoring information such as retweets, likes, and replies on posts, and more. The Buffer for iPhone app allows you to take the service with you wherever you are and check data or post things on the fly. This can be especially useful for business owners that find value in knowing how well their social media techniques are working.

Once you've downloaded the Buffer for iPhone app you can either sign into an existing Buffer account or create a new one. You can sign up for the Buffer service for free and start adding your accounts but you'll be limited to how many accounts you can add on a free plan. If you want to add Facebook pages and multiple Twitter accounts, you'll need to subscribe to the paid plan for $9.99/month through the Buffer site. Free users are also limited to how many posts they can buffer at once as well where paid users have no limitations on posts and can add up to 12 accounts.

While Buffer does work great for free users that just want to monitor their personal profiles, it's really geared towards business owners and those using social networks as marketing tools. Buffer allows you to queue up posts quickly and easily for any of the accounts you'd like. It will then share them with those networks at certain intervals that you've scheduled with the Buffer service online. You can also choose a post now option if you'd rather share the post now instead of queueing it for a later time. Schedules with Buffer are a great way to prevent a social networking site from going stagnant and this is especially important for businesses who need to keep their users engaged.

When it comes to actually queuing up and buffering content, you can embed content from tons of places and include photos, links, and many other media types. Buffer is widely supported across several apps such as Feedly, Reeder, Instapaper, and many more. You can even email things to your Buffer account instantly.

The actual Buffer app for iPhone doesn't give you a lot of the same functionality that you get with the website version but it does the trick while on the go. You can view posts that are ready to go up as well as post them now, edit, or delete them. Unfortunately, you can't change the posting time within the app or schedules at all for that matter. The developers do say that scheduling options are coming to the iPhone app, we just aren't sure when just yet. Some people may not like having to be tethered to a web version of a service but this will be the case, at least for now, with Buffer.

The app will, however, let you view statistics on posts. For instance, with Twitter you can view already posted items and the analytics data for them such as how many people responded to it, retweeted it, or favorited it. You'll also see a potential number of people that may see that post. The more retweets you get, the higher that number will be. The same concept holds true for Facebook, LinkedIn, and App.net.

The good

  • Inexpensive way to manage your networks from the computer and while on the go
  • Nice interface that's easy to navigate around
  • Support for many of the most popular networks
  • Users who don't want to pay a fee can use the Buffer service with their personal accounts, just not actual business pages
  • You can post directly to business pages and Twitter accounts simultaneously, there aren't very many apps out there that let you do this
  • Widely supported by many other apps and platforms, including browser extensions

The bad

  • No Instagram support, this would be killer for sharing photos to Facebook, Twitter, and Instagram simultaneously
  • If you need to edit a Buffer, you'll have to do it across all the networks you've queued it up for - this can be irritating
  • There's no way to change the post time within the Buffer for iPhone app, only post now or queue at the next available time
  • Deleting a post will have to be done across all networks it is shared to individually

The bottom line

Buffer for iPhone is meant to be a complimentary app to an already great service. While the web version is definitely more powerful and where you're meant to spend most of your time, it would still be nice to see some of the web options become available on the iPhone.

It'd also be epic to see Instagram support come to Buffer. I currently can't find any app that will let you post to a Twitter page, Facebook business page, and Instagram all at once and it's something a lot of business users would benefit from.

Aside from that, Buffer is a great service that's very reasonably price and if used correctly, can greatly help businesses better manage their social networks and boost them to their full potential.

T-Mobile simplifies tablet and hotspot data prices, too

T-Mobile

The self-described "Un-Carrier" is also changing up the way it bills for mobile broadband on tablets, hotspots and data sticks today. There is now very little distinction between adding a phone and adding a tablet to your plan, with simplified pricing throughout. For stand-alone devices on their own account, tablets, hotspots, laptops and data sticks will have a base charge of $20 per month for 500MB of high-speed data, throttled to 2G thereafter. Each additional $10 per month adds 2GB to that allotment, all the way up to 12.5GB per month for $80.

If you are adding a tablet, hotspot, laptop or data stick to an existing individual or family plan, the prices are cut by $10 per month. So if you already have a phone line with T-Mobile, adding a tablet with 500MB of data is the same price -- just $10 -- as adding another phone line with 500MB of data.

This is a huge move in the right direction for T-Mobile, as it helps confirm what we all know already -- that data is data, no matter what device you're using it on. The carrier hasn't historically been a popular destination for users wanting tablet and hotspot data plans, but this may help sway some customers going forward.

Laser empties atoms from the inside out

Mar. 25, 2013 ? An international team of plasma physicists has used one of the world's most powerful lasers to create highly unusual plasma composed of hollow atoms.

The experimental work led by scientists from the University of York, UK and the Joint Institute for High Temperatures of Russian Academy of Sciences demonstrated that it is possible to remove the two most deeply bound electrons from atoms, emptying the inner most quantum shell and leading to a distinctive plasma state.

The experiment was carried out using the petawatt laser at the Central Laser Facility at the Science and Technology Facilities Council (STFC) Rutherford Appleton Laboratory to further understanding of fusion energy generation, which employs plasmas that are hotter than the core of the Sun.

The results are reported in the journal Physical Review Letters.

A hollow atom occurs when an electron buried in an atom is removed, usually by being hit by another electron, creating a hole while leaving all the other electrons attached. This process creates plasma, a form of ionised gas. An X-ray is released when the hole is filled.

Normally the process involves removing electrons from the outer shells of atoms first and working inwards. The team of scientists demonstrated a new mechanism for creating hollow atoms that involved emptying atoms from the inside out.

The experimental work used an intense laser, which at one petawatt delivers approximately 10,000 times the entire UK national grid, delivered in a thousand-billionth of a second, onto an area smaller than the end of a human hair.

Dr Nigel Woolsey, from the York Plasma Institute, Department of Physics, at the University of York was the Principal Investigator for the experimental work.

Dr Woolsey said: "At such extraordinary intensities electrons move at close to the speed of light and as they move they create perhaps the most intense X-rays ever observed on Earth. These X-rays empty the atoms from the inside out; a most extraordinary observation and one that suggests the physics of these interactions is likely to change, as lasers become more powerful."

Analysis and theoretical work was led by the Los Alamos National Laboratory, USA and Osaka University, Japan.

The analysis showed the mechanism for hollow atom generation was not due to the collision of electrons or driven by the laser photons, but was driven by the resulting radiation field from the interaction.

Lead author Dr James Colgan, from the Los Alamos National Laboratory, said: "The conditions under which the hollow atoms were produced were highly non-equilibrium and the production mechanism was quite surprising. These results indicate that a little-explored region of physics is now starting to become accessible with the unprecedented intensities reached by the world's leading laser facilities."

Co-author Dr Alexei Zhidkov, from Osaka University, said: "This experiment has demonstrated a situation where X-ray radiation dominates the atomic physics in a laser-plasma interaction; this indicates the importance of X-ray radiation generation in our physics description. Future experiments are likely to show yet more dramatic effects which will have substantial implications for diverse fields such as laboratory-based astrophysics."

If the scientific and technological challenges can be overcome, fusion offers the potential for an effectively limitless supply of safe, environmentally friendly energy. The experimental work was designed to further scientists understanding of how intense lasers can create electron beams with speeds close to the speed of light, then use these beams to heat fusion fuel to thermonuclear temperatures.

Co-author Dr Sergey Pikuz, from the Joint Institute for High Temperatures RAS, said: "The measurements, simulations, and developing physics picture are consistent with a scenario in which high-intensity laser technology can be used to generate extremely intense X-ray fields. This demonstrates the potential to study properties of matter under the impact of intense X-ray radiation."

Co-author Rachel Dance, a University of York PhD physics student, said: "This was a very dynamic experiment which led to an unexpected outcome and new physics. The hollow atom diagnostic was set to measure the hot electron beam current generated by the laser, and the results that came out of this in the end, showed us that the mechanism for hollow atom generation, was not collisional or driven by the laser photons, but by the resulting radiation field from the interaction."

Developing our sense of smell

Mar. 25, 2013 ? When our noses pick up a scent, whether the aroma of a sweet rose or the sweat of a stranger at the gym, two types of sensory neurons are at work in sensing that odor or pheromone. These sensory neurons are particularly interesting because they are the only neurons in our bodies that regenerate throughout adult life -- as some of our olfactory neurons die, they are soon replaced by newborns. Just where those neurons come from in the first place has long perplexed developmental biologists.

Previous hypotheses about the origin of these olfactory nerve cells have given credit to embryonic cells that develop into skin or the central nervous system, where ear and eye sensory neurons, respectively, are thought to originate. But biologists at the California Institute of Technology (Caltech) have now found that neural-crest stem cells -- multipotent, migratory cells unique to vertebrates that give rise to many structures in the body such as facial bones and smooth muscle -- also play a key role in building olfactory sensory neurons in the nose.

"Olfactory neurons have long been thought to be solely derived from a thickened portion of the ectoderm; our results directly refute that concept," says Marianne Bronner, the Albert Billings Ruddock Professor of Biology at Caltech and corresponding author of a paper published in the journal eLIFE on March 19 that outlines the findings.

The two main types of sensory neurons in the olfactory system are ciliated neurons, which detect volatile scents, and microvillous neurons, which usually sense pheromones. Both of these types are found in the tissue lining the inside of the nasal cavity and transmit sensory information to the central nervous system for processing.

In the new study, the researchers showed that during embryonic development, neural-crest stem cells differentiate into the microvillous neurons, which had long been assumed to arise from the same source as the odor-sensing ciliated neurons. Moreover, they demonstrated that different factors are necessary for the development of these two types of neurons. By eliminating a gene called Sox10, they were able to show that formation of microvillous neurons is blocked whereas ciliated neurons are unaffected.

They made this discovery by studying the development of the olfactory system in zebrafish -- a useful model organism for developmental biology studies due to the optical clarity of the free-swimming embryo. Understanding the origins of olfactory neurons and the process of neuron formation is important for developing therapeutic applications for conditions like anosmia, or the inability to smell, says Bronner.

"A key question in developmental biology -- the extent of neural-crest stem cell contribution to the olfactory system -- has been addressed in our paper by multiple lines of experimentation," says Ankur Saxena, a postdoctoral scholar in Bronner's laboratory and lead author of the study. "Olfactory neurons are unique in their renewal capacity across species, so by learning how they form, we may gain insights into how neurons in general can be induced to differentiate or regenerate. That knowledge, in turn, may provide new avenues for pursuing treatment of neurological disorders or injury in humans."

Next, the researchers will examine what other genes, in addition to Sox10, play a role in the process by which neural-crest stem cells differentiate into microvillous neurons. They also plan to look at whether or not neural-crest cells give rise to new microvillous neurons during olfactory regeneration that happens after the embryonic stage of development.

Funding for the research outlined in the eLIFE paper, "Sox10-dependent neural crest origin of olfactory microvillous neurons in zebrafish," was provided by the National Institutes of Health and the Gordon Ross Postdoctoral Fellowship. Brian N. Peng, a former undergraduate student (BS '12) at Caltech, also contributed to the study.

Chief justice's lesbian cousin will attend landmark gay-marriage argument

By Erin McClam, Staff Writer, NBC News

A cousin of Chief Justice John Roberts who wants to marry her lesbian partner in California says she will attend this week?s landmark Supreme Court argument on gay marriage.

Jean Podrasky will sit in a section of the courtroom reserved for relatives and guests of the chief justice. Her partner of four years, Grace Fasano, will attend with her, she told the Los Angeles Times.

Podrasky said that she has no knowledge of the chief justice?s thinking but expects the court to overturn Proposition 8, a ban on gay marriage that was approved by California voters in 2008.

?He is a smart man,? she told the newspaper. ?He is a good man. I believe he sees where the tide is going. I do trust him. I absolutely trust that he will go in a good direction.?

Podrasky, who lives in San Francisco, said that she usually sees the chief justice only on family occasions. She said he knows that she is gay, and that she hopes he will meet her partner during their visit to Washington.

Roberts was appointed by President George W. Bush in 2005. He generally sides with the court?s conservative wing, but last year he sided with liberals on the court in upholding President Barack Obama?s health care overhaul.

The court is hearing two gay-rights cases this week. The argument on Proposition 8 will be Tuesday. The following day, the court will consider the 1996 Defense of Marriage Act, which blocks federal recognition of gay marriages sanctioned by states.

Podrasky told the newspaper that she got the coveted courtroom seats by emailing Roberts? sister, then going through his secretary. She said that Roberts knows she is attending.

In the weeks before the 2008 election, Podrasky carried a sign opposing Proposition 8 at a transit station and handed out fliers on a college campus, the Times reported.

In a column for the National Center for Lesbian Rights to be published Monday, Podrasky writes that ?everyone in this country? has a gay relative.

?As a Californian, I want nothing more than to marry my wonderful girlfriend,? the column says, as quoted by the newspaper. ?And as a tax-paying citizen, I seek basic fairness.?
