From The Australian/AFP:

THE world's biggest atom-smasher, shut down after its inauguration in September 2008 amid technical faults, has been restarted.

"The first tests of injecting sub-atomic particles began around 1600 (01:00 AEDT),'' CERN spokesman James Gillies said.

He said the injections lasted a fraction of a second, enough for "a half or even a complete circuit'' of the Large Hadron Collider built in a 27km long tunnel straddling the Franco-Swiss border near Geneva.

Little Progress In Freeing A Rover On Mars

NASA's Mars Rover Spirit took this image with its front hazard-avoidance camera on May 6. Wheel slippage during attempts to extricate it from a patch of soft ground during the preceding two weeks had partially buried the wheels. NASA

From The New York Times:

The NASA rover Spirit, stuck in sand on Mars, tried to move Tuesday for the first time since May. In less than a second, it stopped.

Cautious mission managers had put tight constraints on the Spirit’s movement to ensure that it did not drive itself into a deeper predicament. Because the uncertainty in its tilt was more than one degree, the rover called it a day. Spirit awaits new instructions.

Norwegian Scientists Detect Mutated Form Of Swine Flu


From The Washington Post:

Norwegian scientists detect mutated form of swine flu.

Scientists in Norway announced Friday they had detected a mutated form of the swine flu virus in two patients who died of the flu and a third who was severely ill.

In a statement, the Norwegian Institute of Public Health said the mutation "could possibly make the virus more prone to infect deeper in the airways and thus cause more severe disease," such as pneumonia.

The institute said there was no indication that the mutation would hinder the ability of the vaccine to protect people from becoming infected or impair the effectiveness of antiviral drugs in treating people who became infected.

Studying A Legend: K.E. Tsiolkovskii, Grandfather of Soviet Rocketry

From The Space Review:

Anyone who has studied the history of the space age has come across the name Konstantin Tsiolkovskii (1857–1935), often under the more common alternative spelling Tsiolkovsky. He is generally credited with the development of the basic mathematical formulae for space travel. Other than that, he is often described as the man who after the revolution inspired a small group of space enthusiasts, including Glushko and Korolev, to begin serious work on rocket technology. The details of his life, as James Andrews explains in his new study of the man, are more complex and far more interesting than the legend.

Pushing The Brain To Find New Pathways


From Science Daily:

Science Daily (Nov. 19, 2009) — Until recently, scientists believed that, following a stroke, a patient had about six months to regain any lost function. After that, patients would be forced to compensate for the lost function by focusing on their remaining abilities. Although this belief has been refuted, a University of Missouri occupational therapy professor believes that the current health system is still not giving patients enough time to recover and underestimating what the human brain can do given the right conditions.

Water Shortages Spur Restrictions and Low-Flow Designs, but Some People Aren't Willing to Sacrifice, and Skirt the Rules

One way to ruin someone's day is to mess with a good morning shower. That was the hard-learned lesson of past campaigns to conserve water -- and a mistake that could be easy to repeat.

Margy Barrett, a store manager in Dallas, will make some environmental sacrifices. She recycles, and she carts reusable cloth bags to the grocery store. But this month, when she couldn't stand her weak shower head any longer, she replaced it with one that sprays hard enough, she says, to help erode "all the stress involved in today's life."

Remembering Dr. Paul Zamecnik

Although Dr. Paul Zamecnik was nominated repeatedly for the Nobel and rumors circulated each year that he would finally receive it, the prize never came. He did, however, win a 1996 Lasker Award, the prestigious American prize that is often a precursor of the Nobel, and the National Medal of Science in 1991. (Mercer Photography / University of Massachusetts Medical School)

Dr. Paul Zamecnik Dies At 96; Scientist Made Two Major Discoveries -- L.A. Times

He discovered transfer RNA, a crucial molecule in the synthesis of proteins in the cell, and antisense therapy, in which strands of DNA or RNA are used to block the activity of genes.

Most scientists are fortunate if they can make one major discovery in their lifetime. Dr. Paul Zamecnik made two, each of which should have won him a Nobel Prize.

Working with Dr. Mahlon Hoagland, he discovered transfer RNA, a crucial molecule in the synthesis of proteins in the cell. Later, he invented the idea of antisense therapy, in which strands of DNA or RNA are used to block the activity of genes -- a concept that is now being turned into a new class of drugs for cancer, HIV and a host of other diseases.

Zamecnik died of cancer Oct. 27 at his home in Boston. He was 96.

Yawning Is Part Of What Makes Us Human

Chimps do it, dogs do it, lions do it, even babies in the womb do it Photo: AFP

From The Telegraph:

Far from being bad manners, yawning is a sign of our deep humanity, says Steve Jones.

What may become 2010's Conference of the Year has just been announced. The International Congress of Chasmology will take place in June in Paris, and papers are solicited now. Anyone bored by that statement should read further, for the topic to be discussed is not diving but yawning ('chasmology' deriving from the Greek word for the pastime).

Why do we yawn? Dogs do it, lions do it, even babies in the womb do it - but nobody really knows why. Theories abound. We open wide when we are tired, bored, or hungry. Some have suggested that a sudden drop in blood oxygen, or a surge of carbon dioxide pumped out by a tired body, sparks it off – but no, breathing air rich in that gas, or with extra oxygen, makes no difference.

Sounds During Sleep Aid Memory, Study Finds


From The New York Times:

Science has never given much credence to claims that you can learn French or Chinese by having the instruction CDs play while you sleep. If any learning happens that way, most scientists say, the language lesson is probably waking the sleeper up, not causing nouns and verbs to seep into a sound-asleep mind.

But a new study about a different kind of audio approach during sleep gives insight into how the sleeping brain works, and might eventually come in handy to people studying a language, cramming for a test or memorizing lines in a play.

From Time Magazine:

Like the vast forests of the world, which continually suck carbon dioxide from the atmosphere and release oxygen, the planet's oceans serve as vital carbon sinks. Last year the oceans absorbed as much as 2.3 billion tons of carbon, or about one-fourth of all manmade carbon emissions. Without the action of the oceans, the CO2 we emit into the atmosphere would have flame-broiled the planet by now.

From Live Science:

Jim White is a professor of Geological Sciences and the Director of the Environmental Studies Program at the University of Colorado at Boulder, and is leading research being conducted on the Greenland ice sheet. White is also the director of The Institute of Arctic and Alpine Research (INSTAAR), which focuses on studying the effects of environmental changes in high altitude and high latitude regions. White's research on the Greenland ice sheet is part of the North Greenland Eemian Ice Drilling (NEEM) project. Fourteen nations are collaborating in the NEEM research, with the common goal of obtaining samples of core ice from the Eemian Period, which was the last interglacial period, about 120,000 years ago. The samples will help researchers interpret the atmospheric environment present during the Eemian period, and relate those interpretations to the present day atmosphere. The ultimate goal of this research is to learn more about how the Earth's climate functions, and what, if anything, can be done to counteract any adverse environmental conditions. The core ice samples will also help researchers identify the causes behind the Earth's increased warming, including those driven by human activity. Below, White answers the ScienceLives 10 Questions.

Antarctic Temperature Spike Surprises Climate Researchers

Photo: Is Antarctica more sensitive to global warming that we thought? Getty

From Nature:

Polar region was unexpectedly warm between ice ages.

During the warm periods between recent ice ages, temperatures in Antarctica reached substantially higher levels than scientists had previously thought. This conclusion, based on ice-core studies, implies that East Antarctica is more sensitive than it seemed to global warming.

Previous estimates suggested that peak temperatures during the warmest interglacial periods — which occurred at around 125,000, 240,000 and 340,000 years ago — were about three degrees higher than they are today. But a team led by Louise Sime of the British Antarctic Survey in Cambridge, UK, concludes that Antarctica was actually around six degrees warmer.

From Technology Review:

Long-lived nuclear batteries powered by hydrogen isotopes are in testing for military applications.

Batteries that harvest energy from the nuclear decay of isotopes can produce very low levels of current and last for decades without needing to be replaced. A new version of the batteries, called betavoltaics, is being developed by an Ithaca, NY-based company and tested by Lockheed Martin. The batteries could potentially power electrical circuits that protect military planes and missiles from tampering by destroying information stored in the systems, or by sending out a warning signal to a military center. The batteries are expected to last for 25 years. The company, called Widetronix, is also working with medical-device makers to develop batteries that could last decades for implantable medical devices.

After a century buried in the Antarctic ice, a rare batch of whisky that belonged to the polar explorer Sir Ernest Shackleton is to be recovered. So what might it taste like?

It's been on the rocks for the last 100 years, buried under two feet of Antarctic ice. Now the two cases of "Rare Old" brand Mackinlay and Co whisky are to be retrieved.

A team of New Zealand explorers heading out in January has been asked by Whyte & Mackay, the company that now owns Mackinlay and Co, to get a sample of the drink. The crates were left behind by Sir Ernest Shackleton when he abandoned his mission to the South Pole in 1909.

My Comment: I will now formally volunteer to be a taster for any whiskey that is retrieved.

From Science Daily:

Science Daily (Nov. 17, 2009) — Using ESO's Very Large Telescope and its ability to obtain images as sharp as if taken from space, astronomers have made the first time-lapse movie of a rather unusual shell ejected by a "vampire star," which in November 2000 underwent an outburst after gulping down part of its companion's matter. This enabled astronomers to determine the distance and intrinsic brightness of the outbursting object.

It appears that this double star system is a prime candidate to be one of the long-sought progenitors of the exploding stars known as Type Ia supernovae, critical for studies of dark energy.

No Surprise: Coed Dorms Fuel Sex and Drinking


From Live Science:

It's no secret to students that coed dorms are more fun than same-sex dorms. But they can also fuel very unhealthy behavior that might otherwise be moderated.

A new study finds university students in coed housing are 2.5 times more likely to binge drink every week. And no surprise, they're also likely to have more sexual partners, the study found. Also, pornography use was higher among students in coed dorms.

Some 90 percent of U.S. college dorms are now coed.

From The Guardian:

X-rays of mummies reveal atherosclerosis, suggesting there may be more to heart disease than bad diet and smoking.

Heart disease plagued human society long before fry-ups and cigarettes came along, researchers say. The upper classes of ancient Egypt were riddled with cardiovascular disease that dramatically raised their risk of heart attacks and strokes.

Doctors made the discovery after taking hospital X-ray scans of 20 Egyptian mummies that date back more than 3,500 years.

From Time Magazine:

There was a time when Wendy and her husband had sex three times a week. But for the past six years, the purple negligee that Wendy used to entice her husband has been stuffed in the back of a drawer. And now, instead of getting hot and bothered by her husband's advances, Wendy is simply bothered. "All of a sudden I didn't have any desire. There's just nothing there anymore," says Wendy, who requested that her last name not be published.
