The Hugh Hefner Syndrome – How A Good-looking Partner Makes You More Attractive
From The Telegraph:
Having an attractive mate on your arm makes you look more attractive in the eyes of the opposite sex, claim scientists in research that could explain the continuing appeal of Hugh Hefner.
However going out with a better looking friend of the same sex can have the opposite effect.
Researchers have found that we bask in the reflective glory of our more attractive partners because others assume we must have hidden talents away from our looks.

Amazing Pictures: Space Shuttle Discovery Soars Through The Clouds Before Landing Safely (After A 2,000 Mile Diversion)
Edwards Air Force Base near Rosamond, California.
From the Daily Mail:
The space shuttle Discovery landed safely in California early today after bad weather forced a switch of its touchdown site at the end of a two-week mission to the International Space Station.
NASA diverted the spaceship to Edwards Air Force Base in California's Mojave Desert after waiting in vain for two days for rain and clouds to clear over the shuttle's home port in Florida, the originally scheduled landing location.
Under partly cloudy desert skies, the shuttle landed at 0053 GMT.

White Dwarf "Close" To Exploding As Supernova
From Universe Today:
ESA’s XMM-Newton orbiting X-ray telescope has uncovered the first close-up of a white dwarf star that could explode into a type Ia supernova within a few million years. That's relatively soon in cosmic time frames, and although this white dwarf that is orbiting its companion star HD 49798, is far enough away to pose no danger to Earth, it is close enough to become an extraordinarily spectacular celestial sight. Calculations suggest that it will blaze initially with the intensity of the full Moon and be so bright that it will be seen in the daytime sky with the naked eye. But don't worry, it will be awhile!

Evolution Coup: Study Reveals How Plants Protect Their Genes
From Science Daily:
ScienceDaily (Sep. 11, 2009) — Unlike animals and humans, plants can't run and hide when exposed to stressful environmental conditions. So how do plants survive? A new Université de Montréal study, published in the journal Proceedings of the National Academy of Sciences, has found a key mechanism that enables plants to keep dangerous gene alterations in check to ensure their continued existence.

Predicting Extraterrestrial Weather
From Live Science:
Maybe even more than average citizens, the world's space agencies rely on daily and seasonal reports to better understand weather on Earth and other planets. Space-mission success ties directly to effective anticipation and navigation of inclement surface and atmospheric conditions.
Mission-design engineers at NASA, the European Space Agency (ESA), and similar organizations need to know what environmental issues a Mars Lander or Rover might face to ensure that heat shields, parachutes and other on-board mechanisms survive the trip through the atmosphere to the surface.

The Coming Battle Over Fresh Water
As water becomes increasingly scarce, we may have to charge for every drop.
In a now-famous interview with The New York Times in 1995, Ismail Serageldin, the World Bank’s vice president for environmentally sustainable development, said, “Many of the wars in this century were about oil, but wars of the next century will be over water.” While the situation is currently considerably less dire in the United States than in many other places around the world, an escalating fight over water in the coming years is in the making. We are “entering an era of water reallocation, when water for new uses will come from existing users who have incentives to use less,” says Robert Glennon, the Morris K. Udall professor of law and public policy at the University of Arizona, in his new book Unquenchable: America’s Water Crisis and What to Do About It. Those reallocations can take place through contentious politicking and in the courts, or, Glennon argues, more peaceably, through market forces.

Why The DOJ Wants More On Yahoo Search Deal
The long road toward Microsoft and Yahoo's search deal could be set to get a little longer, or fall off a cliff.
Both companies have long expected the U.S. Department of Justice to scrutinize the deal to install Microsoft as the exclusive search provider for Yahoo's Web pages, which would also see Yahoo end its time as a search company. Microsoft and Yahoo confirmed Friday that the Justice Department has asked the two companies for more information about their deal, which is a step beyond taking a mere interest in the proceedings.

NASA Names Target For Water Hunt At Moon's South Pole
From L.A. Times:
The LCROSS satellite and rocket are to plunge into the surface Oct. 9, stirring up a dust cloud that may contain ice. The find would have major scientific implications and aid future space plans.
NASA scientists announced Friday that they had picked a 60-mile-wide crater near the moon's south pole as the place where they will send a rocket to punch a hole in the lunar surface next month in search of water.
Instruments aboard other satellites and on Earth have detected a significant amount of hydrogen, a telltale marker for water, on the northwest rim of the crater known as Cabeus A.

On the Scene: NASA's Huge Rocket Test
From Space.com:
PROMONTORY, UTAH – After two previous cancellations of debut engine tests of NASA's new Ares I rocket, there was a bit of trepidation among the spectators near the ATK Space Systems test facility in Promontory Point, Utah.
On Thursday afternoon, ATK successfully test fired the Ares I rocket's first stage, a giant solid-fueled booster, that will be used to launch astronauts on NASA's Orion spacecraft no earlier than 2015. We were on location to witness the high tech fireworks show [SEE VIDEO], $75 million in the making. And while the price tag might be a bit daunting, the spectacle of the test-firing and the magnitude of the Ares project were truly breathtaking

Aage Bohr
From The Telegraph:
Aage Bohr, who died on September 8 aged 87, was a pioneering nuclear physicist and Nobel Prize winner; in his youth he escaped from Nazi-occupied Denmark with his father, Niels Bohr, a central figure in the Manhattan Project, to whom Aage was a valuable assistant.
The Bohr family fled from Denmark to neutral Sweden in 1943 after Hitler had ordered the deportation of Danish Jews. From Sweden the Bohrs headed for London where Niels became involved in what Aage was later to call, somewhat euphemistically, "the atomic energy project".

Nanotubes Could Enable Self-Repairing Electronic Circuits
From Popular Science:
Researchers develop nanotubes that can help circuits repair critical breaks.
Many people know the familiar wince when a cell phone or laptop hits the floor. But electronic devices of the future may self-repair tiny cracks or breaks in their circuitry with the help of nanotubes.
Researchers from the University of Illinois at Urbana-Champaign have created capsules that hold conductive nanotubes and can sit on circuit boards. Mechanical stress that causes a crack in the circuit would also split open some capsules and release the nanotubes to help bridge the gap.

Potato Blight Has The Genome Of Death
From New Scientist:
THE blight that triggered the great famine in Ireland in 1845 is still the biggest disease threat to spuds worldwide - and it's no wonder.
Researchers have sequenced the genome of the mould that causes blight and found it keeps a huge arsenal of potato-destroying genes, ready to evolve around whatever defences taters can muster. On the plus side, the sequence also suggests ways to fight back.

Life in the Dark: How Organisms Survived Asteroid Impacts
Credit: Charles University in Prague.
From Live Science:
A dinosaur-killing asteroid may have wiped out much of life on Earth 65 million years ago, but now scientists have discovered how smaller organisms might have survived in the darkness following such a catastrophic impact.
Survival may have depended upon jack-of-all-trades organisms called mixotrophs that can consume organic matter in the absence of sunlight. That would have proved crucial during the long months of dust and debris blotting out the sun, when plenty of dead or dying organic matter filled the Earth's oceans and lakes.

Killer Whales Strain to "Talk" Over Ship Noise?
The San Juan killer whales "talk" more during foraging than traveling, researchers said in September 2009. But since the whales also have to raise their voices to be heard above boat noise, scientists worry that the animals may be using up too much energy during hunts, even as their preferred prey, chinook salmon, are on the decline. Photograph courtesy Center for Whale Research via AP
From National Geographic:
Killer whales raise their voices to be heard over boat noise, and the effort may be wearing the whales out as they try to find food amid dwindling numbers of salmon, new research says.
The killer whales of Puget Sound make more calls and clicks while foraging than while traveling, suggesting that such mealtime conservations are key to coordinating hunts, the work reveals.

Junk Cost Estimates Supplied to Augustine Committee Threaten to Sink NASA's Human Spaceflight Program
From The Mars Society:
The Mars Society has examined copies of the cost projections being used by the Augustine Committee in currently considering the future of NASA's human spaceflight program. These estimates, generated by the Aerospace Corporation, a US Air Force funded policy oracle, have no scientific basis and have clearly been composed to make the case that human space exploration is unaffordable.
A copy of the Aerospace Corporation's bizarre cost estimates being used by the Augustine Committee is available here.Read more ....
Earlier Model of Human Brain's Energy Usage Underestimated Its Efficiency
From Scientific American:
A long-held model of the brain's efficiency crumbles as researchers find that one function of mammals' brains consumes a lot less energy than previously assumed. Now, basic measurements of neural activity--from brain energy budgets to fMRI results--may have to be reassessed.
The human brain is an incredible energy drain. Taking up only about 2 percent of the body's mass, the organ uses more than a fifth of bodily energy. Ever more accurate calculations of its energy budget at the level of the neuron (nerve cell) are important to researchers ranging from functional magnetic resonance imaging (fMRI) analysts to evolutionary biologists.

E-book Readers Still Owned By Small Niche
From CNET:
The tech industry buzzes a lot about e-book readers. But how widely are they actually used?
Among 1,529 consumers who responded to a July 2009 questionnaire from research firm In-Stat, only 5.8 percent currently own an e-book reader. And only 11 percent of those questioned said they planned to buy one in the next 12 months, according to the In-Stat report released this week.
Those low results may be even more significant given that In-Stat's survey audience consisted of high-end consumers who typically adopt new technology earlier than the general public.

Brain Cells Slicker Than We Thought
Rat brain cells waste little energy when talking to one another. That finding might not sound unusual, but it challenges the long-standing view that brain cells are extremely inefficient at sending signals.
In 1939, Alan Hodgkin of the University of Cambridge and Andrew Huxley of University College London experimented on nerve cells from the giant squid. They concluded that the energy of electrical signals sent along axons – the cells' "cables", each 1 millimetre in diameter in the giant squid – was four times the theoretical minimum.

Where Did All the Flowers Come From?
From The New York Times:
Throughout his life, Charles Darwin surrounded himself with flowers. When he was 10, he wrote down each time a peony bloomed in his father’s garden. When he bought a house to raise his own family, he turned the grounds into a botanical field station where he experimented on flowers until his death. But despite his intimate familiarity with flowers, Darwin once wrote that their evolution was “an abominable mystery.”

Wolves Aren’t Making It Easy for Idaho Hunters
From The New York Times:
BOISE NATIONAL FOREST, Idaho — Hunting and killing are not the same thing. Even as Idaho has sold more than 14,000 wolf-hunting permits, the first 10 days of the first legal wolf hunt here in decades have yielded only three reported legal kills.
Such modest early results might seem surprising in a state that has tried for years to persuade the federal government to let it reduce the wolf population through hunting.
Idahoans, among the nation’s most passionate hunters, are learning that the wolf’s small numbers — about 850 were counted in the state at the end of last year — make it at once more vulnerable and more elusive.

NASA's Plans Lack The Cash
From Technology News:
On Tuesday, after months of deliberation, the independent committee charged with reviewing the future of the U.S. human space program released a summary report of its findings, a document that will guide key decisions that lie ahead for the Obama administration.
According to the report, the current crisis facing NASA lies with its budget, and not with technical or programmatic issues. "The report clearly stated that the current program is not executable or sustainable with the budget that we have," says Scott Pace, director of the Space Policy Institute at George Washington University, in DC.

The iPod Is Dead
From Slate:
One sign that Steve Jobs is back to his old self: He's already sniping at rivals. After Apple's iPod launch event on Wednesday, the New York Times' David Pogue asked the CEO whether he has doubts—as he's expressed in the past—about the market for e-readers, especially Amazon's Kindle. Jobs said he was still skeptical. Amazon, he pointed out, has never released sales numbers for the Kindle, and "usually, if they sell a lot of something, you want to tell everybody." More importantly, Jobs doesn't think people want to buy a device just to read books. "I'm sure there will always be dedicated devices, and they may have a few advantages in doing just one thing," Jobs said. "But I think the general-purpose devices will win the day."

Memories Exist Even When Forgotten, Study Suggests
From Science Daily:
ScienceDaily (Sep. 10, 2009) — A woman looks familiar, but you can't remember her name or where you met her. New research by UC Irvine neuroscientists suggests the memory exists – you simply can't retrieve it.
Using advanced brain imaging techniques, the scientists discovered that a person's brain activity while remembering an event is very similar to when it was first experienced, even if specifics can't be recalled.

Computer Could Call Football Plays
From Live Science:
WASHINGTON (ISNS) -- Football coaches are famous for their dedication to winning. Video studies of upcoming opponents begin so early in the morning that most people are still dreaming about their first cup of coffee; strategy sessions run past the time insomniacs fall asleep.
But a new computer model may be able to take the play calling load off of the coach and, through fast, real-time analysis of all the offensive and defensive possibilities, dictate the best play to call in any game situation. The program takes the human element out of play calling and instead uses mathematical and statistical techniques.

Diamonds Are For Softies – Boron Is Harder
From New Scientist:
You don't often break a diamond. So when in 2003 Dave Mao cracked a tooth of his diamond anvil, he knew something extraordinary must have happened. Together with his daughter Wendy and other colleagues at the Geophysical Laboratory of the Carnegie Institution for Science in Washington DC, he was using the device to test materials at pressures many millions of times higher than those at the Earth's surface - higher even than in our planet's core - by squeezing them between two tiny diamond jaws.

The Working Person's Diet: Too Busy to Eat Right
From Time Magazine:
If you've ever gotten so busy at work that you skipped lunch and ended up staring at your hungry reflection in the vending-machine glass in the late afternoon, then you're familiar with this gastro-economic catch-22: losing your job may mean cutting back on food bills, but gainful employment could result in poor eating habits overall.
That's the conclusion of a new nutritional study by researchers at Cornell University. They conducted a survey of 25 working mothers and 25 working fathers in low-to-moderate-income communities and found that more than half of the participants routinely resorted to unhealthy eating options because of their work circumstances.

Why Washing May Hamper Your Attractiveness
From The Independent:
A natural chemical found in the sweat of men has been shown to act as a primitive love potion that increases their attractiveness in the eyes of women, a study has found.
The substance, which is derived from the male sex hormone testosterone, has a small but significant effect on judgements made by women in a speed-dating situation of a male stranger's attractiveness.
Tamsin Saxton of the University of St Andrews studied the influence of androstadienone by dabbling a drop of it on the upper lip of 50 women who took part in the evening trial before they "dated" a series of men.

Do Mention The War, Say Scientists
From The Telegraph:
Encouraging old people to talk about the war is good for their health, claim scientists.
Researchers have found that when the elderly sat around in groups discussing old times it improved their memory and limited the effects of dementia.
Reminiscence therapy, as it is technically known, could increase the cognitive recall and agility of the mind by up to 12 per cent in as little as six weeks, it was found.

Simpler, Fresher Facebook Lite Puts Twitter In The Shade
From The Daily Mail:
Facebook is currently testing a simplified version of its social network service aimed at countries where internet bandwidth is limited. But it may prove popular with other users tired of the currently over-fussy website.
The new system, named Facebook Lite, focuses on messaging and user updates and now looks far more similar to rival micro-blogging service Twitter.
It is available to a handful of users in the UK by going to http://lite.facebook.com. However, at present a preview of the service is only widely available in India and the US.
Shuttle Landing Delayed For A Day
The landing of the shuttle Discovery at the Kennedy Space Center has been delayed for at least a day due to bad weather in Florida.
Thunderstorms and strong winds meant that the US space agency Nasa skipped both Thursday landing possibilities.

Arctic May Be Changed Forever, Study Finds
From Live Science:
The dramatic changes sweeping the Arctic as a result of global warming aren't just confined to melting sea ice and polar bears — a new study finds that the forces of climate change are propagating throughout the frigid north, producing different effects in each ecosystem with the upshot that the face of the Arctic may be forever altered.
"The Arctic as we know it may be a thing of the past," said Eric Post of Penn State, who led an international team that brought together research on the effects of climate change from ecosystems across the Arctic.

Is Warfare in Our Genes? Apparently Not
OPTIMISTS called the first world war "the war to end all wars". Philosopher George Santayana demurred. In its aftermath he declared: "Only the dead have seen the end of war". History has proved him right, of course. What's more, today virtually nobody believes that humankind will ever transcend the violence and bloodshed of warfare. I know this because for years I have conducted numerous surveys asking people if they think war is inevitable. Whether male or female, liberal or conservative, old or young, most people believe it is. For example, when I asked students at my university "Will humans ever stop fighting wars?" more than 90 per cent answered "No". Many justified their assertion by adding that war is "part of human nature" or "in our genes". But is it really?

Solar Superstorm
From NASA:
October 23, 2003: Newly uncovered scientific data of recorded history's most massive space storm is helping a NASA scientist investigate its intensity and the probability that what occurred on Earth and in the heavens almost a century-and-a-half ago could happen again.
In scientific circles where solar flares, magnetic storms and other unique solar events are discussed, the occurrences of September 1-2, 1859, are the star stuff of legend. Even 144 years ago, many of Earth's inhabitants realized something momentous had just occurred. Within hours, telegraph wires in both the United States and Europe spontaneously shorted out, causing numerous fires, while the Northern Lights, solar-induced phenomena more closely associated with regions near Earth's North Pole, were documented as far south as Rome, Havana and Hawaii, with similar effects at the South Pole.
