From CNET News:

Yahoo and Microsoft have finalized their agreement to install Microsoft as the exclusive search provider for Yahoo's network of sites, the companies announced Friday.


The deal, first reached in July, still needs to be approved by the U.S. government before it becomes final. But the companies said in October that they needed more time to complete the deal due to the "complex nature of this transaction," and Friday's announcement is likely the result of hundreds of hours of painstaking review from expensive lawyers.

From The Telegraph:

Scientists have created the world’s smallest 'snowman', measuring about a fifth of the width of a human hair.

Experts at the National Physical Laboratory in West London made the miniature figure which is just 0.01mm across.

However, far from the thrill of rolling balls of snow around a field to build their masterpiece, it was assembled using tools designed for manipulating nanoparticles.

From Air And Space Smithsonian:

Shortly after 9 p.m. on a rainy February night in Los Angeles, Tony Chong switched on his home computer, logged into eBay, and began his nightly aircraft hunt. For more than two decades, Chong had been making exquisite aircraft models at Northrop Grumman’s display model shop—and collecting the rare desktop models his company and other U.S. airplane makers distributed to promote their programs. Often the listings on eBay were for castoffs, but that night in 2005 one model gave him a jolt: Painted in mottled camouflage and balanced on a familiar pentagon base, it was an 18-inch-long concept model of a Northrop Grumman FB-23 advanced bomber.

Physicists Race To Publish First Results From LHC

Large Hadron Collider

From New Scientist:

Good things come to those who wait. But now that the Large Hadron Collider has restarted after undergoing more than a year of repairs, physicists are racing to analyse the data. Just days after the first protons were smashed together at the LHC, the first paper on the results has been accepted to a journal.

The first collisions took place on Monday, 23 November; by Saturday, a paper had been uploaded to the arxiv server, where physicists often publish their results prior to formal publication. Three days later, it had been accepted by the European Journal of Physics.

Mysterious "Strange" Stars May Rival Black Holes For Weirdness

In this top-down illustration of a black hole and its surrounding disk, gas spiraling toward the black hole piles up just outside it, creating a traffic jam. The traffic jam is closer in for smaller black holes, so X-rays are emitted on a shorter timescale. By NASA

From USA Today:

Think black holes are strange? Understandable considering these powerhouses of the universe (many times heavier than our sun) are collapsed stars with gravity so strong that even light cannot escape their grasp.

But maybe they're not "strange" enough, suggest some astrophysicists. "Stellar" black holes, ones only a few times heavier than the sun, may actually be something even weirder called a quark star, or "strange" star.

Shark Fins Traced To Home Waters Using DNA -- A First

Workers remove the fin from a female mako shark on a beach in Santa Rosalia, Mexico, in an undated picture. For the first time, scientists have used DNA analysis to trace shark fins back to their home waters. Most of the hammerhead fins found at the market came from endangered populations in the western Atlantic, the researchers said in December 2009. Photograph by Brian J. Skerry, NGS

From National Geographic:

Many of the hammerhead sharks that are butchered to feed Asian demand for shark-fin soup start their lives in American waters, a new forensic study shows.

For the first time, scientists have used DNA from shark fins to determine where they came from. The researchers traced finds from the scalloped hammerhead shark species—collected at the world's biggest fin market in Hong Kong—back to rare populations in the Atlantic and Indo-Pacific oceans.

From Science Daily:

Science Daily (Dec. 3, 2009) — Washington, D.C.—Hawaii may be paradise for vacationers, but for geologists it has long been a puzzle. Plate tectonic theory readily explains the existence of volcanoes at boundaries where plates split apart or collide, but mid-plate volcanoes such as those that built the Hawaiian island chain have been harder to fit into the theory. A classic explanation, proposed nearly 40 years ago, has been that magma is supplied to the volcanoes from upwellings of hot rock, called mantle "plumes," that originate deep in the Earth's mantle. Evidence for these deep structures has been sketchy, however. Now, a sophisticated array of seismometers deployed on the sea floor around Hawaii has provided the first high-resolution seismic images of a mantle plume extending to depths of at least 1,500 kilometers (932 miles).

Sound Body Equals Sound Mind, Study Finds

Exercise improves blood flow to the brain and may help build new brain cells, recent studies show. Image credit: Dreamstime

From Live Science:

A new study proves the old Roman saying, "A sound mind in a sound body" — the more fit one's heart is, the more one's brain seems to benefit, scientists now find.

Many earlier studies have linked physical exercise with brainpower in humans and animals, but most of the research in people focused on children or older adults. The few studies of young adulthood — when the brain changes rapidly, establishing many traits linked with intelligence — have yielded ambiguous data.

From Technology Review:

New design does away with the need for a complex gearbox.

A Canadian startup has developed a small prototype wind turbine that uses friction instead of a gearbox to convert wind energy into electricity. CWind, based in Owen Sound, Ontario, recently began work on a larger two-megawatt prototype. The company claims that its "friction drive" system is more efficient and reliable--and less costly to maintain--than conventional wind turbines, which are prone to expensive gearbox failures.

No Need For Specs: Eye Implants Offer ‘Super Vision’

From Times Online:

People who have to wear glasses in middle or old age could have their eyesight restored or even obtain “supervision” with the latest eye implants, a British surgeon says.

Light-adjustable lenses (LAL) offer the prospect of 20/20 vision to thousands of people who become short-sighted or develop cataracts with age.

The lenses are similar to existing lens implants, or intraocular lenses (IOL), used to treat cataracts. But doctors can adjust them after they have been implanted, tailoring the amount of correction to an individual’s needs and potentially eliminating the need for glasses.

That's The Spirit! Stuck Mars Rover Stirs Up Exciting New Proof Of Water In Sand Trap

Free spirit: Hundreds of images taken by the Spirit rover between May and June 2009 built up this panoramic view of Mars. The tracks made by the rover are visible

From The Daily Mail:

When one of Nasa's rovers became stuck in a sand trap on Mars six months ago, scientists were frustrated it had stalled their search for water on the surface.

Now it appears it could have been the best thing to have happened to the mission.

As Nasa span the Spirit rover's wheels to try and manoeuvre it out of the ditch, they simply dug deeper into the soft sand. However this had churned up an intriguing bright fluffy material from the disturbed soil.

How Europe's Discarded Computers Are Poisoning Africa's Kids

Photo from Clemens Höges

From Spiegel Online:

People in the West throw away millions of old computers every year. Hundreds of thousands of them end up in Africa, where children try to eke out a living by selling the scrap. But the toxic elements in the waste are slowly poisoning them.


According to the Bible, God rained down fire and brimstone to destroy the cities of Sodom and Gomorrah. "Sodom and Gomorrah" is also what officials in Accra, Ghana, have come to call a part of their city plagued by toxins of a sort the residents of the Biblical cities couldn't even have imagined. No one sets foot in this place unless they absolutely have to.

Have We Discovered It All?

Funding for medical research is now estimated to be in the
region of $100 billion worldwide Photo: AFP


From The Telegraph:

Billions are spent on medical research, but we have entered an era of diminishing returns.

When Andy Burnham, the Health Secretary, admitted last week that he was going to have to "re-prioritise" £60 million of the Government's medical research budget, diverting it to help pay for social care for the elderly and disabled, it seemed a blatant example of robbing Peter to pay Paul. It is self-evident, after all, that today's research will reap dividends in the future, whether through new treatments, or novel ways of thinking about and preventing disease.

First Direct Observation Of A Planet-Like Object Orbiting Star Similar To Sun

This August 2009 discovery image of GJ 758 B was taken with the Subaru Telescope's HiCIAO instrument in the near infrared, which measures and records differences in heat. Without the special technique employed here (angular differential imaging), the star's glare would overwhelm the light from the planet candidates. The planet-like object, GJ 758 B, is circled as B in the lower right portion of the image. An unconfirmed companion planet or planet-like object, C, can be viewed above B. The star, GJ 758, is located at the center of the image, at the hub of the starburst. The graphic at the top compares the orbital distances of solar system planets.

From Live Science:

If you're feeling a little overwhelmed by all the information you have to keep track of, you're not alone. Between the proliferation of 'smart' devices — ranging from phones to power grids — and the ever-growing Internet, the world is drowning in data. But not to despair, computer scientists like Juliana Freire are trying to help us gather and make sense of this modern monsoon of data. A computer scientist at the University of Utah, Freire's work centers on finding data that might otherwise be missed, as well as integrating and managing that data into knowledge that people can actually use. She and her collaborators have created the DeepPeep project, an attempt at integrating typical web-based data with other databases that are publicly available, but not easily found through standard methods like online searching. Freire has also created a tool called VisTrails that allows users to take several computers and 24 large, flat-screen video monitors and produce a single high-resolution visualization, such as the brain's vascular system or the dynamics of an erupting volcano. For more about the work, see the recent NSF Discovery feature story. For more on Freire, see her answers to the ScienceLives 10 Questions below.
