'Master of science fiction' author Frederik Pohl dies at age 93
Sep 3rd 2013, 16:53

Acclaimed science fiction author Frederik Pohl died yesterday at age 93, according to his official website.

The Space Merchants author was admitted to a hospital the morning of September 2 in respiratory distress and died later in the afternoon.

"We're teary and shell-shocked right now, but we'll have more news soon," a note on the author's website read. His granddaughter Emily Pohl-Weary was the first to break the news when she tweeted, "Rest in peace to my beloved grandfather Frederik Pohl who showed me by example how to be an author. 1919-2013."

Considered a pioneering author in the science fiction genre, Pohl enjoyed a successful career, spanning over 75 years.

Along with the death announcement, the note on his website promised more to come for Pohl readers. "Fred left a thick file of things he wanted to tell you, so we'll likely keep posting for a while," the site read.

On giant blue alien planet, it rains molten glass
Sep 3rd 2013, 15:00

There's a "blue marble" alien planet just 63 light-years from Earth, but the world is anything but friendly to life. Researchers say the blue color in the atmosphere likely comes from a rain of molten glass.

This super-hot glass rain is just one consequence of the close proximity between the gas giant alien planet HD189733b and its sun. which causes daytime temperatures to soar as high as 1,700 degrees Fahrenheit, scientists said.

A fresh set of observations of the planet in X-rays also suggest HD189733b has an outer atmosphere that is far larger than expected. [See more images of the blue alien planet HD 189733b]

These surprise finds are all signals that so-called hot Jupiter alien planets are worthy of study on their own, even though they are hostile planets to life, researchers said.

Rewriting planetary formation
Hot Jupiters are large, roughly Jupiter-sized planets that become very hot by circling tight around their stars. These worlds have been described as planetary daredevils because they orbit so close to their parent stars that they risk being consumed. Often, one side of the planet is tidally locked to the star, exposing that side to scorching hot temperatures, while leaving the other side permanently turned away.

Hot Jupiters are easy to spot from a distance because as they pass in front of a star, their disc blots out a large portion of the star's light; HD189733b causes a three per cent drop in its star's light, for example. The planets' gravitational pull often causes their parent stars to wobble, too.

While common in the universe, however, Hot Jupiters are totally different than what denizens of Earth's solar system encounter. In our case, small, rocky planets orbit close to the star and the gas giants are much farther out.

The latest observations of HD189733b are challenging some theories of planetary formation and are just one of the reasons Hot Jupiters are earning more attention from astronomers these days.

"At first considered to be the 'chaff' researchers would have to wade through to get to the fainter Earth-like worlds, hot Jupiters are now attracting their own attention," NASA scientists wrote in a recent Science@NASA post about these planets.

Boiling atmosphere
New attention came to HD189733b, which was discovered in 2005, after two X-ray observatories watched the blue planet pass across the face of its star. Both NASA's Chandra X-Ray Observatory and ESA's XMM Newton saw a drop in X-rays from the star that was three times more than that observed in optical light.

This means the planetary atmosphere is much larger than previously thought. It's also bleeding quickly. HD189733b's atmosphere is fleeing the planet at a rate of 220 million pounds to 1.3 billion pounds a second, a new study estimated.

"The extended atmosphere of this planet makes it a bigger target for high-energy radiation from its star, so more evaporation occurs," Scott Wolk, an astronomer at the Harvard-Smithsonian Center for Astrophysics, said in a statement.

HD189733b could also have bright planet-wide auroras due to the extensive stellar radiation hitting it, but that's speculation at this point, the study authors said.

The study has been accepted for publication in the Astrophysical Journal, and is available now on the prepublishing site Arxiv.

Scientists spark auroras in a bottle for traveling Northern Lights show
Sep 3rd 2013, 15:45

The glowing colors and dancing lines of the Northern Lights could soon appear inside an educational institution near you.

A small device called Planeterrella bottles all the ingredients needed for the naturally occurring lights show — a magnetic field, a sphere and charged particles — and creates a mini version of the auroras inside.

The concept, which was imported from Europe, will be on display at the Virginia Air and Space Center in a few months. Another device will travel from classroom to classroom. [Video of aurora lights in "virtual real time"]

In addition to offering a Northern Lights display, Planeterrella can also, in limited form, show the differences between aurora on different planets.

Where charged particles collide
Auroras are common on planets with magnetic fields, such as Earth. Particles streaming from the sun hit Earth's magnetic field lines and travel to the magnetic north and south poles. As the particles brush with Earth's upper atmosphere, they excite atoms of nitrogen, oxygen and other gases and cause the lights.

These dancing lights have also been spotted on other planets in the solar system, including Mars, Jupiter, Saturn, Uranus and Neptune. Other processes could also contribute to the aurora; on Saturn, for example, some researchers say a rain of particles from its ring could help light up the skies.

Planeterrella works to capture this process in miniature. Its European creators drew inspiration from a 19th century experiment called Terrella, which showed how charged particles glow when they hit a magnetic field. Planeterrella includes several spheres to better recreate how auroras wrap around Earth's poles.

Research limitations
The machine, said lead researcher Guillaume Gronoff in a statement, is intended to illustrate the differences in how aurora are generated at different planets.

"The Planeterrella allows us to create analogies with existing processes, like the aurora at Mars, which do not have a global magnetic field, but several localized magnetic fields, or Uranus and Neptune, when the magnetic fields of those planets point towards the sun," said Gronoff, who is a research scientist at NASA Langley Research Center in Virginia.

The experiment is not a perfect recreation, however, as it does not show the whole picture.

"For example, there are various gases on each planet that can create different color effects within auroras," NASA scientists said in a statement. "Gronoff is planning on incorporating this variable using a few extra magnets and some carbon dioxide to simulate the aurora at Mars."

Planeterrella's creator was Gronoff's Ph.D. advisor, Jean Lilensten. Lilsensten is from the Centre national de la recherche scientifique and the Institut de Planetologie et d'Astrophysique de Grenoble in France.

Weird! Tiny frog hears through its mouth
Sep 3rd 2013, 14:00

A small frog native to the Republic of Seychelles lacks a conventional middle ear and eardrum to hear sounds made by other frogs, but new research suggests these peculiar croakers are not deaf, and can instead use their mouth cavities to pick up on noise.

Gardiner's frogs from the Seychelles islands are one of the smallest known types of frogs in the world. These amphibians are seemingly deaf having no middle ear or eardrum to help process sound waves but can mysteriously still make their own croaking sounds, and hear the calls of other frogs. In a new study, researchers used X-ray imaging to peer inside the frogs' heads, finding they use their mouth cavities to amplify sounds that travel to the inner ear through connective tissue.

Most four-legged animals have middle ears that contain small, bony ossicles that take vibrations from the eardrum and transmit the sound waves from the air to the fluid-filled cochlea. [Image gallery: Cute and Colorful Frogs]

"However, we know of frog species that croak like other frogs but do not have tympanic middle ears to listen to each other. This seems to be a contradiction," lead study researcher Renaud Boistel, of the French National Center for Scientific Research (Centre National de la Recherche Scientifiqueor CNRS) in Paris, France, said in a statement.

To determine that Gardiner's frogs do, in fact, use sound to communicate with one another, the scientists set up loudspeakers in the natural rain forests of Seychelles and played pre-recorded frog songs. Males in the rain forests promptly answered the songs, signifying they could hear the recording, the researchers said.

Several ideas had been suggested for how the Gardiner's frogs could hear sounds, including extra auditory pathways through the lungs or special muscles in the frogs that connect to the inner ear.

"Whether body tissue will transport sound or not depends on its biomechanical properties," study co-author Peter Cloetens, a scientist at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, said in a statement. "With X-ray imaging techniques here at ESRF, we could establish that neither the pulmonary system nor the muscles of these frogs contribute significantly to the transmission of sound to the inner ears."

By studying X-ray images and numerical simulations, the researchers discovered that Gardiner's frogs receive sound through their heads. The mouth amplifies the frequencies and the sound is transmitted through tissue and bones in the skull to the inner ear.

The X-ray images showed reduced thickness and fewer layers of tissue between the frogs' mouths and their inner ears, compared with other frog species, which suggests these auditory adaptations were likely the result of evolutionary forces in Gardiner's frogs, the researchers said.

"The combination of a mouth cavity and bone conduction allows Gardiner's frogs to perceive sound effectively without use of a tympanic middle ear," Boistel said.

The detailed findings of the study were published online Monday (Sept. 2) in the journal Proceedings of the National Academy of Sciences.

FOX News: Study: Future storms may be less likely to follow Sandy's path

Study: Future storms may be less likely to follow Sandy's path
Sep 3rd 2013, 07:28

Man-made global warming may further lessen the likelihood of the freak atmospheric steering currents that last year shoved Superstorm Sandy due west into New Jersey, a new study says.

But don't celebrate a rare beneficial climate change prediction just yet. The study's authors said the once-in-700-years path was only one factor in the massive $50 billion killer storm. They said other variables such as sea level rise and stronger storms will worsen with global warming and outweigh changes in steering currents predicted by the study's computer models.

"Sandy was an extremely unusual storm in several respects and pretty freaky. And some of those things that make it more freaky may happen less in the future," said Columbia University atmospheric scientist Adam Sobel, co-author of a new study on Sandy. But Sobel quickly added, "There's nothing to get complacent about coming out of this research."

The study published Tuesday in the journal Proceedings of the National Academy of Sciences looks at the giant atmospheric steering currents, such as the jet stream. A spate of recent and controversial studies has highlighted unusual kinks and meanders in the jet stream, linking those to extreme weather and loss of sea ice in the Arctic. This new study looks only at the future and sees a lessening of some of that problematic jet stream swerving, clashing with the other studies in a scientific debate that continues.

Both camps agree on what happened with the weird steering that shoved Sandy, a late season hurricane that merged with a conventional storm into a massive hybrid, into New Jersey. The jet stream plunged in an odd way. A high pressure system off the coast of Canada and Greenland blocked the storm from moving east, as most do.

That high pressure block now happens once or twice a year in August, September and October.  Computer models show the jet stream will move further north, so the "giant blob of high pressure" will be even less frequent next century, said study lead author Elizabeth Barnes of Colorado State University.

But Barnes and Sobel said because so many other factors are involved this doesn't mean fewer storms hitting the New York region. This is only one path; storms usually come from the south instead of from the east like Sandy.

Scientists agree that future storms will be slightly stronger because of global warming and that sea level is rising faster than researchers once thought, Sobel said. Those factors likely will overwhelm the predicted change in steering currents, he said.

Rutgers University climate scientist Jennifer Francis, one of the major proponents of the jet-stream-is-changing theory, said she doesn't see the jet stream becoming stronger and moving north as Barnes says the models predict. Her work and others points to more Sandy-like storms, especially because there seem to be more late-season tropical storms.

"The matter is not settled," said Pennsylvania State University climate scientist Michael Mann.

Florida asks, is that a panther or a monkey?
Sep 2nd 2013, 10:00

WEST PALM BEACH, Fla. –  A year after launching an online site for Florida panther sightings, state wildlife officials are finding the data useful, even if the occasional report turns out to be a fox -- or even a monkey.

Yes, a monkey.

Wildlife biologists are using reports from the public to help track the population of endangered Florida panthers, a citizen-science effort similar to those used to track populations of birds, fish and other animals.

A year after launching its online site, biologists with the Florida Fish & Wildlife Conservation Commission have received 790 reports of panther sightings from most parts of the state, complete with GPS coordinates.

The problem: Only 12 percent of the reports included photographs of the animal, or its tracks, that could be used to verify whether the reporter truly saw a Florida panther.

The majority of the reports submitted with photos were verified as Florida panthers, the FWC said. Other animals mistaken for panthers included bobcats, foxes, coyotes, dogs, house cats and a monkey.

Darrell Land, leader of the FWC's panther team in Naples, said the public reporting effort helps biologists track the expanding range of the panther, whose population is estimated at 100 to 160. Although the panther is still a rare sight, the population has grown substantially from the 30 to 40 cats thought to exist during the late 1980s.

Counting panthers is difficult because they are solitary, elusive and wide-ranging animals.

"To properly plan and manage for the expansion of the panther's range in Florida, information about where the panthers are is vital," Land said.

Most of the verified reports to the FWC's website were from southwest Florida, the well-established breeding range for Florida panthers. But a few of the verified sightings were north of Lake Okeechobee, an indication that panthers could be roaming farther to find food and establish territory.

None of the sighting reports from Palm Beach County was verified as a panther sighting, Land said.

The animal most commonly mistaken for a panther, or its tracks, was the bobcat.

The website www.FloridaPanthernet.org includes photos and tips for identifying the tracks of panthers, which leave no claw imprints when walking and have three distinct lobes at the rear edge of the heel pad. A bobcat track looks similar, but it's about a third the size of a panther track.

Land encouraged the public to submit photos of panther tracks using the website, which includes a Google map tool that allows users to zoom in on a location and pinpoint the coordinates.

"If it's a good-quality track, we can get a positive ID on it," Land said.

Land hopes more photos of panthers captured on game cameras -- stand-alone cameras left in the woods that are triggered when animals pass by -- will be shared with the FWC.

If an observer is lucky enough to see a panther with a camera ready, photos of the elusive cats are useful, even if they're taken with a phone.

But Land advises against moving closer to a panther to get a better photo. Although there are no documented cases of anyone being mauled by a panther, they're large, wild cats, with adult males weighing 100 to 160 pounds.

"Make sure they know you're there so there's no element of surprise," Land said.

The concept of using the observations of many to benefit animal research dates back to 1900, when ornithologist Frank Chapman organized the first Christmas Bird Count, then an alternative to Christmas Day bird hunts.

An online reporting site for fox squirrels launched in 2011 resulted in 4,221 location reports over eight months. The sighting locations helped determine what natural and urban habitats the fox squirrels were using, said Courtney Tye, an FWC wildlife biologist in Gainesville who is tracking four species of fox squirrels.

"Information provided by the public is invaluable in locating imperiled wildlife," Tye said.

Pennsylvania hospital to open country's first inpatient treatment program for Internet addiction
Sep 1st 2013, 07:15

Ten years ago, Kevin Roberts suffered from an addiction that took over his life.

Roberts, now 44 years old, would sit eight to 12 hours a day in front of the pale blue glow of his computer, playing a videogame. During holidays, he "binged," spending nearly all his waking hours at his keyboard. Finally, a friend who had been through Alcoholics Anonymous told him he displayed all the same characteristics of an addict.

"Like most addicts, I went through a series of self-deception," said Roberts, who documented his struggle with addiction in his book, ."  

The story of Roberts, who came to grips with his addiction through years of therapy and spiritual retreats, is not unique. Treatment facilities have sprung up in recent years, but a psychiatric hospital in central Pennsylvania is now set to become the country's first facility of its kind to offer an inpatient treatment program for people it diagnoses with severe Internet addiction.

The voluntary, 10-day program is set to open on Sept. 9 at the Behavioral Health Services at Bradford Regional Medical Center. The program was organized by experts in the field and cognitive specialists with backgrounds in treating more familiar addictions like drug and alcohol abuse.

"[Internet addiction] is a problem in this country that can be more pervasive than alcoholism," said Dr. Kimberly Young, the psychologist who founded the non-profit program. "The Internet is free, legal and fat free."

"[Internet addiction] is a problem in this country that can be more pervasive than alcoholism."

- Dr. Kimberly Young

The program is designed to accommodate four adult patients at a time, with each new class slated to begin treatment on the same day. These classes take part in group therapy and are placed inside a wing of the hospital designated for other addicts. These patients will undergo a psychological evaluation and learn ways they can minimally use the Internet and avoid problematic applications.  

Young and other experts are quick to caution that mere dependence on modern technology does not make someone an Internet addict. The 20-year-old who divides his time between his girlfriend and "World of Warcraft" likely does not require intensive treatment. The program is designed for those whose lives are spiraling out of control because of their obsession with the Internet. These individuals have been stripped from their ability to function in daily life and have tried in the past to stop but cannot.

The idea that someone can suffer from Internet addiction first surfaced in the mid-1990s, and Young presented her first paper on the issue in front of the American Psychological Association in 1996. But as the Internet's popularity grew and became a staple in most people's lives, so has the recognition that portion of the population shows signs of being addicted.

Most people with a severe Internet addiction have some type of undiagnosed psychiatric disorder or personality problem, according to Dr. Roger Laroche, the medical director of the department of psychiatry at Bradford Regional. Each patient in the program, which costs $14,000 out-of-pocket because insurance does not cover the expense, will be psychologically evaluated after undergoing a 'digital detox.'

A 'digital detox' is when the patient is cut off from any Internet connection or computer use for 72 hours. For many, the thought of being disconnected from the Internet may feel like a vacation.

But for those with the addiction, they can face withdrawals similar to those seen in people addicted to marijuana. These patients can face depression, irritability and in some cases violence, Laroche said.

Young said one of her outpatients once resorted to chewing Styrofoam cups and unloaded punches into a wall during his detox. In 2010, researchers at the University of Maryland conducted a study where 200 students were asked not to use any form of media for 24 hours, Reuters reported. At the end of the study, many students reported feeling withdrawn and suffered anxiety.

Last May, the American Psychiatric Association released its Diagnostic and Statistical Manual of Mental Disorders 5, or DSM-5, for the first time listed "Gaming Disorder" in Section III of the manual, which means it requires further research before being formally identified as a disorder.

The association noted evidence that young men from Asian countries in particular become engrossed in Internet games and "certain pathways in their brains are triggered in the same direct and intense way that a drug addict's brain is affected by the substance."

Dr. Allen Frances, the chairman of the DSM-IV and professor emeritus at Duke University has been a critic of formally identifying Internet addiction as a disorder. He said its listing in Section III of the manual means the disorder "wasn't ready for primetime."

He said there's little doubt that a small population can suffer from some form of Internet addiction, but believes the research is premature. For example, he asks, where do you draw the line at addiction and recreational use?

"If we can be addicted to gambling and the Internet, why not also include addictions to shopping, exercise, sex, work, golf, sunbathing, model railroading, you name it? All passionate interests are at risk for redefinition as mental disorders," he wrote in an op-ed in The Huffington Post titled, "Internet Addiction: The Next New Fad Diagnosis."
