Pictured: Three Bald Eagles Lock Talons As They Plunge To The Ground In Mid-Air Battle

The three hungry bald eagles lock talons in a vicious mid-air battle for a fish supper

From The Daily Mail:

Locked in desperate mid-air battle, the three eagles plunge towards the ground in a contest to see who will let go last.

Between their claws lies a gasping fish freshly plucked from an Alaskan lake, now the target of fearsome talons as each eagle grapples for supper.

This is not so much a desperate bid for food - instead it's a macho show of strength between three birds who want to show who's who in the pecking order.

Counting Money 'Makes People Feel Better About Themselves'

Research suggests that counting cash makes people feel better about themselves.

From The Telegraph:

Counting money can make you feel good about yourself – even if it isn't your own, according to a new study.

Just handling and thinking about money can actually lessen pain and even ease the social stigma of having no friends, researchers believe.

The psychological benefits increase feelings of internal strength, fearlessness and confidence.

Pause In Arctic's Melting Trend

Photo: Walrus have been seen on Alaska's north coast in unusual numbers

From The BBC:

This summer's melt of Arctic sea ice has not been as profound as in the last two years, scientists said as the ice began its annual Autumn recovery.

At its smallest extent this summer, on 12 September, the ice covered 5.10 million sq km (1.97 million sq miles).

This was larger than the minima seen in the last two years, and leaves 2007's record low of 4.1 million sq km (1.6 million sq miles) intact.

But scientists note the long-term trend is still downwards.

How Last.fm Inspired A Scientific Breakthrough

From The Guardian:

I first saw Mendeley pitch two weeks ago – now it is on the way to changing the face of science.

The music radio site Last.fm is one of the great ideas from the UK during the first dotcom boom. Users can listen to their own songs and other tracks recommended by Last.fm's algorithms based on their tastes, including iTunes, and those of friends. It could easily have been a one-trick pony. But now a few academics have applied its serendipity to scientific research. Why can't researchers, instead of waiting anywhere up to three years for their papers to jump all the hurdles, be part of a real-time market place – a fusion of iTunes and Last.fm for science?

Women Really Can't Keep A Secret: Tongues Start Wagging After Just 47 Hours

Spilling the beans: Women cannot keep a secret for longer than 47 hours

From The Daily Mail:

Ever wondered how long a woman can keep a secret? Well the answer, it seems, is less than two days.

Researchers found that they will typically spill the beans to someone else in 47 hours and 15 minutes.

A study of 3,000 women aged between 18 and 65 also found that four in ten were unable to keep a secret, no matter how personal or confidential the news was.

From The New Scientist:

NEUROSCIENCE could do for schools what biomedical research has done for healthcare. That's the conclusion of the Decade of the Mind (DOM) symposium last week in Berlin, Germany, to discuss how the latest findings could be used to improve education.

"In medicine, we have an excellent system in place to go from basic research to clinical practice, while in neuroscience we have the basic understanding of how the brain learns but still need to figure out how to translate this into the classroom," says Manfred Spitzer of the University of Ulm in Germany, one of the conference organisers.

Can Robots Make Ethical Decisions?

From Live Science:

Robots and computers are often designed to act autonomously, that is, without human intervention. Is it possible for an autonomous machine to make moral judgments that are in line with human judgment?

This question has given rise to the issue of machine ethics and morality. As a practical matter, can a robot or computer be programmed to act in an ethical manner? Can a machine be designed to act morally?

Killer Whales Die Without King Salmon

King Salmon: It's What's for Dinner. A killer whale snags a king salmon. Some killer whale populations favor king salmon so much that the whales will actually die when numbers of this largest member of the salmon family drop. Brian Gisborne

From Discovery News:

Sept. 16, 2009 -- Some killer whale populations favor king salmon so much that the whales will actually die when numbers of this largest member of the salmon family drop, according to new research.

The study, published in the latest Royal Society Biology Letters, suggests that although killer whales may consume a variety of fish species and mammals, many are highly specialized hunters dependent on this single salmon species.

Facebook Grows And Makes Money

From The BBC:

The world's largest social networking site just got bigger with the announcement it has 300 million active monthly users from around the globe.

Facebook also revealed that it had started making money ahead of schedule.

From Technology Review:

Nanosolar's new factory could help lower the price of solar power, if the market cooperates.

A promising type of solar-power technology has moved a step closer to mass production. Nanosolar, based in San Jose, CA, has opened an automated facility for manufacturing its solar panels, which are made by printing a semiconductor material called CIGS on aluminum foil. The manufacturing facility is located in Germany, where government incentives have created a large market for solar panels. Nanosolar has the potential to make 640 megawatts' worth of solar panels there every year.

From Cosmos:

SYDNEY: A mathematical equation that counts habitats suitable for alien life could complement the Drake equation, which estimates the probability of finding intelligent alien beings elsewhere in the galaxy.

That equation, developed in 1960 by U.S. astronomer Frank Drake, estimates the probability of intelligent life existing elsewhere in our galaxy by considering the number of stars with planets that could support life (see "Are we alone?").

From New Scientist:

FORGET the risk of exploding rockets or getting sideswiped by a wayward bit of space junk. Radiation may be the biggest hurdle to human exploration beyond low-Earth orbit and could put a damper on a recently proposed mission to Mars orbit.

A panel tasked by the White House with reviewing NASA's human space flight activities (New Scientist, 22 August, p 8) suggests sending astronauts to one of Mars's moons, Phobos or Deimos, among other possibilities raised in its report released last week (http://tinyurl.com/mbajav).

Apollo Moon Rocks Lost In Space? No, Lost On Earth

This photo from the Boerhaave Museum in Leiden, Netherlands shows authentic Dutch moon rocks on display. The detection of a fake moon rock in the Netherlands' Rijksmueum should serve as a wake-up call for more than 130 countries who received gifts of lunar rubble from both the Apollo 11 flight in 1969 and Apollo 17 three years later. Experts say the whereabouts are unknown of hundreds of tiny rocks scooped up by U.S. astronauts and given by the Nixon administration to friendly nations. Photo from AP

The Science of Hunger: What 1 Billion People Feel

From Live Science:

Despite a record level of people suffering from hunger, food aid is at a 20-year low due to the poor global economy, United Nations officials said today. The result: More than 1 billion people across the world will face hunger this year.

"For the world's most vulnerable, the perfect storm is hitting with a vengeance," said U.N. World Food Program (WFP) Executive Director Josette Sheeran. So far this year, the agency has received less than half of the $6.7 billion it needs to feed 108 million people in 74 countries, Sheeran said.

From Scientific American:

Scientists can climb inside the University of California, Santa Barbara's three-story-high AlloSphere for a life-size interaction with their research.

Scientists often become immersed in their data, and sometimes even lost. The AlloSphere, a unique virtual reality environment at the University of California, Santa Barbara, makes this easier by turning large data sets into immersive experiences of sight and sound. Inside its three-story metal sphere researchers can interpret and interact with their data in new and intriguing ways, including watching electrons spin from inside an atom or "flying" through an MRI scan of a patient's brain as blood density levels play as music.
