Killer Whales Visit 'Social Clubs'

From BBC:

Killer whales create and visit social clubs just like people do, scientists have discovered.

Up to 100 fish-eating killer whales come together in the Avacha Gulf, off the coast of Russia.

But no-one knew why the whales form these huge superpods, when they normally live in smaller groups.

Now scientists report in the Journal of Ethology that these groups act as clubs in which the killer whales form and maintain social ties.

Planet Smash-Up Sends Vaporized Rock, Hot Lava Flying

This artist's concept shows a celestial body about the size of our moon slamming at great speed into a body the size of Mercury. NASA's Spitzer Space Telescope found evidence that a high-speed collision of this sort occurred a few thousand years ago around a young star, called HD 172555, still in the early stages of planet formation. The star is about 100 light-years from Earth. (Credit: NASA/JPL-Caltech)

From Science Daily:

ScienceDaily (Aug. 12, 2009) — NASA's Spitzer Space Telescope has found evidence of a high-speed collision between two burgeoning planets around a young star.

Astronomers say that two rocky bodies, one as least as big as our moon and the other at least as big as Mercury, slammed into each other within the last few thousand years or so -- not long ago by cosmic standards. The impact destroyed the smaller body, vaporizing huge amounts of rock and flinging massive plumes of hot lava into space.

Men Not Choosy In One-Night Stands

From Live Science:

It's no secret that men are more likely than women to jump into the sack. But a new study adds some twists to the rules of such casual sex.

The research suggests men are far less choosy about the attractiveness of a potential one-night stand. For women to be tempted into considering casual sex, the guy better be a hottie.

These results, based not on real-life encounters but rather on interviews, match with past research showing that men lower their standards when it comes to one-night stands. And it turns out, from the new study, women raise their standards.

General Motors CEO Fritz Henderson says the EPA will certify the Chevrolet Volt with triple-digit mileage. How'd they come up with that?

General Motors calls the Chevrolet Volt an extended-range electric vehicle. That's because the only motive force comes from the electric motor; the gas engine only charges the batteries. In a press conference earlier today, GM's CEO Fritz Henderson said the Volt will have a city mileage figure of 230 miles per gallon--almost five times more efficient than a Prius. But considering the uniqueness of the Volt's powertrain, how did the EPA get that figure?

Mars, Methane And Mysteries

From Scientific American:

Mars may not be as dormant as scientists once thought. The 2004 discovery of methane means that either there is life on Mars, or that volcanic activity continues to generate heat below the martian surface. ESA plans to find out which it is. Either outcome is big news for a planet once thought to be biologically and geologically inactive.

The methane mystery started soon after December 2003, when ESA's Mars Express arrived in orbit around the red planet. As the Planetary Fourier Spectrometer (PFS) began taking data, Vittorio Formisano, Istituto di Fisica dello Spazio Interplanetario CNR, Rome, and the rest of the instrument team saw a puzzling signal. As well as the atmospheric gases they were anticipating, such as carbon monoxide and water vapour, they also saw methane. "Methane was a surprise, we were not expecting that," says Agustin Chicarro, ESA Mars Lead Scientist. The reason is that on Earth much of the methane in our atmosphere is released by evolved life forms, such as cattle digesting food. While there are ways to produce methane without life, such as by volcanic activity, it is the possible biological route that has focused attention on the discovery.

What's Luck Got To Do With It? The Math Of Gambling

From New Scientist:

FIVE years ago, Londoner Ashley Revell sold his house, all his possessions and cashed in his life savings. It raised £76,840. He flew to Las Vegas, headed to the roulette table and put it all on red.

The wheel was spun. The crowd held its breath as the ball slowed, bounced four or five times, and finally settled on number seven. Red seven.

Revell's bet was a straight gamble: double or nothing. But when Edward Thorp, a mathematics student at the Massachussetts Institute of Technology, went to the same casino some 40 years previously, he knew pretty well where the ball was going to land. He walked away with a profit, took it to the racecourse, the basketball court and the stock market, and became a multimillionaire. He wasn't on a lucky streak, he was using his knowledge of mathematics to understand, and beat, the odds.

First Black Holes Born Starving

FROM SCIENCE DAILY

The first black holes in the universe

The simulations were carried out by astrophysicists Marcelo Alvarez and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University, and John Wise, formerly of KIPAC and now of NASA Goddard Space Flight Center.
Several popular theories posit that the first black holes gorged themselves on gas clouds and dust in the early universe, growing into the supersized black holes that lurk in the centers of galaxies today. However, the new results, published in The Astrophysical Journal Letters, point to a much more complex role for the first black holes.
"I'm thrilled that we now can do calculations that start to capture the most relevant physics, and we can show which ideas work and which don't," said Abel. "In the next decade, using calculations like this one, we will settle some of the most important issues related to the role of black holes in the universe."

Biggest Meteor Shower of the Year Peaks Tonight

From Wired News:

Stay up past midnight, grab a blanket and go stargazing tonight: The year’s most spectacular meteor shower is expected to peak Wednesday morning around 1 a.m., and then again just before dawn.

The Perseid meteor shower happens every year in August, when the Earth travels through a cloud of debris left by the periodic comet Swift-Tuttle, which last approached the Earth in 1992. Under optimal conditions, up to 80 shooting stars can be seen every hour, although how many you’ll see tonight depends on cloud cover, the brightness of the moon and the proximity of city lights.

The Flu Hunters: Racing To Outsmart A Pandemic

Research student Nick Cattle, working in the flu lab at the World Influenza Centre
Philip Hollis for TIME

From Time Magazine:

On April 25, Rod Daniels, the deputy director of the World Influenza Centre in London, was at a meeting in Germany when he received a call from a co-worker: an influenza outbreak had been reported in Mexico and the first samples of the virus were on their way to London for examination. A virologist who has studied flu for more than 30 years, Daniels knew exactly what he was looking for. Influenza A viruses — the type that can cause pandemics — use a protein called hemagglutinin to bind to the cells of their animal hosts. When a virus jumps from animals to humans, its contagiousness is largely determined by what is called the "binding specificity" of this protein. An alpha-2,3 binding specificity means the virus is well suited to the cells in an animal respiratory tract but probably not human cells. An alpha-2,6 binding specificity, on the other hand, means the virus can easily bind to human cells.

Saturn's Rings to Disappear Tuesday

Magnificent blue and gold Saturn is seen in 2007, as one of its moons, Dione, hangs in the distance. A day on Saturn is pretty short, and it just got shorter. The time it takes the beringed behemoth to complete a spin on its axis has just been calculated by astrophysicists at 10 hours, 34 minutes and 13 seconds, more than five minutes shorter than previous estimates. (AFP/NASA-HO/File)

Perseid Meteors To Shower Down Late Tuesday, Early Wednesday

From Salt Lake Tribune:

The most-watched meteor shower of the year is coming back late Tuesday and into Wednesday morning, and this year, stargazers may be treated to even more fiery streaks of light zooming across the night sky.

Under the right conditions, observers away from city light pollution are sometimes able to see an average of one and sometimes two Perseid meteors per minute, said Patrick Wiggins, NASA solar system ambassador to Utah.

"But this year," he said, "NASA is predicting the possibility of an enhanced shower Wednesday morning between 2 and 3 a.m."

The more frequent meteor sightings could happen if the Earth passes through what astronomers suspect to be a particularly rich pocket of meteor-producing particles cast off by the shower's parent comet nearly 400 years ago in 1610.

Earth Rotational Periods Cause Ice Ages And Warmings

From Future Pundit:

Changes in how large planets such as Jupiter and Saturn pull at the Earth's rotation cause the Earth to go into periodic cooling and warming periods.

CORVALLIS, Ore. – Researchers have largely put to rest a long debate on the underlying mechanism that has caused periodic ice ages on Earth for the past 2.5 million years – they are ultimately linked to slight shifts in solar radiation caused by predictable changes in Earth's rotation and axis.

In a publication to be released Friday in the journal Science, researchers from Oregon State University and other institutions conclude that the known wobbles in Earth's rotation caused global ice levels to reach their peak about 26,000 years ago, stabilize for 7,000 years and then begin melting 19,000 years ago, eventually bringing to an end the last ice age.

1 Million MPH Stars Move Through Galaxy

From FOX News/Space:

Stars in a distant galaxy move at stunning speeds — greater than 1 million mph, astronomers have revealed.

These hyperactive stars move at about twice the speed of our sun through the Milky Way, because their host galaxy is very massive, yet strangely compact. The scene, which has theorists baffled, is 11 billion light-years away. It is the first time motions of individual stars have been measured in a galaxy so distant.

While the stars' swiftness is notable, stars in other galaxies have been observed to travel at similarly high speeds. In those situations, it was usually because they were interlopers from outside, or circling close to a black hole.

From Science Daily:

ScienceDaily (Aug. 9, 2009) — The rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years, probably because of a warmer world, according to research published in the July issue of Nature Geoscience.

If the band continues to migrate at just less than a mile (1.4 kilometers) a year, which is the average for all the years it has been moving north, then some Pacific islands near the equator – even those that currently enjoy abundant rainfall – may be drier within decades and starved of freshwater by midcentury or sooner. The prospect of additional warming because of greenhouse gases means that situation could happen even sooner.

Why 'Willy' Could Never Be Free

Keiko in home waters. Credit: F. Ugarte/arc-pic.com

From Live Science:

In 1998, with much fanfare, a 20-year-old orca named Keiko took a one-way trip on an Air Force cargo plane from Oregon to Iceland. There, attended by dozens of biologists and trainers, and at a cost reportedly topping $20 million, the orca was gradually reintroduced to his native waters.

Keiko, of course, had starred in three "Free Willy" movies, which sparked a public campaign to free him after nineteen years in captivity.

But things didn’t quite turn out as planned.

A team of his former caretakers, led by Malene J. Simon of the Greenland Institute of Natural Resources in Nuuk, has analyzed logs of Keiko’s behavior and data from satellite tags recording his travels and dives. They point out that Keiko never managed to integrate with Icelandic orca pods and didn’t seem to do much diving or fishing. He spent two several-week-long stretches on his own at sea, but ultimately chose to return to human care.

Hurricane Season 2009: Where Are All the Storms?

El Niño conditions over the Pacific Ocean have so far kept a lid on the 2009 Atlantic hurricane season, experts said in August 2009. But there's still plenty of time for a "monster" to form by season's end. Hurricane Andrew, seen above barreling toward Florida on August 24, 1992, also formed during an El Niño year. Andrew was the third most powerful hurricane to make U.S. landfall in recorded history. Photograph courtesy National Oceanic and Atmospheric Administration (NOAA)

From National Geographic:

Before the 2009 Atlantic hurricane season kicked off on June 1, forecasters were calling for 12 named storms, with about half developing into hurricanes.

Now, about two months into the season, zero storms have formed in the Atlantic.

That's because El Niño conditions over the Pacific Ocean have so far kept a lid on the 2009 hurricane season, experts say.

Still, meteorologists warn that a monster hurricane could be spawned before the season ends on November 30.

"Oases of favorable conditions" could exist in the Atlantic Basin long enough to allow a powerful storm to form, said Keith Blackwell, a meteorologist at the University of South Alabama's Coastal Weather Research Center in Mobile.

"It's very plausible that we still could get one or two intense hurricanes this year," Blackwell said. "And it only takes one to make it a bad season."

Virtual Computer Army Takes On The Botnets

From New Scientist:

MORE than 1 million virtual computers are set to provide insight into how networks of infected computers called botnets wreak havoc on the internet, as the Conficker worm did recently.

Ron Minnich and Don Rudish of Sandia National Laboratories in Livermore, California, crammed 250 independent linux "kernels" - the core system of a computer - onto each of 4400 networked Thunderbird machines, creating a total of over 1.1 million individual virtual computers.

While this network cannot mimic the internet's estimated 600 million computers, the duo hope to use it to study how a small number of machines can attack and bring down larger networks. They can also study, for example, why some botnets prefer to be small and others large.

How The Apple Tablet Could Ruin Computing

The Mythical Apple Tablet, Imagined: via Gizmodo

From Popular Science:

Hint: the mobile network providers are involved.

Though whispers of an Apple tablet device practically predate Australopithecus, this week they’ve reached a fever pitch. It’s been reported by several news outlets that the supposed iTablet will feature a 10-inch touchscreen, both Wi-Fi and 3G data, and a custom ARM processor. It’s already been priced at $800 and even greenlit by none other than His Majesty Steve Jobs for a September release. Not one iota of this has been officially confirmed, but the prospect of a Mac Tablet seems more within reach than ever before.

This is not a good thing. If an Apple tablet is ever actually released, we should all be very concerned for the future of what most of us take for granted today: our d

Breakfast Can Wait. The Day’s First Stop Is Online.

From The New York Times:

Karl and Dorsey Gude of East Lansing, Mich., can remember simpler mornings, not too long ago. They sat together and chatted as they ate breakfast. They read the newspaper and competed only with the television for the attention of their two teenage sons.

That was so last century. Today, Mr. Gude wakes at around 6 a.m. to check his work e-mail and his Facebook and Twitter accounts. The two boys, Cole and Erik, start each morning with text messages, video games and Facebook.

The new routine quickly became a source of conflict in the family, with Ms. Gude complaining that technology was eating into family time. But ultimately even she partially succumbed, cracking open her laptop after breakfast.

“Things that I thought were unacceptable a few years ago are now commonplace in my house,” she said, “like all four of us starting the day on four computers in four separate rooms.”

Freaky Sleep Paralysis: Being Awake In Your Nightmares

From Wired Science:

You wake up, but you can’t move a muscle. Lying in bed, you’re totally conscious, and you realize that strange things are happening. There’s a crushing weight on your chest that’s humanoid. And it’s evil.

You’ve awakened into the dream world.

This is not the conceit for a new horror movie starring a ragged middle-aged Freddie Prinze Jr., it’s a standard description of the experience of a real medical condition: sleep paralysis. It’s a strange phenomenon that seems to happen to about half the population at least once.
