Nobel Awarded for Advances in Harnessing Light -- New York Times

The mastery of light through technology was the theme of this year’s Nobel Prize in Physics as the Royal Swedish Academy of Sciences honored breakthroughs in fiber optics and digital photography.

Half of the $1.4 million prize went to Charles K. Kao for insights in the mid-1960s about how to get light to travel long distances through glass strands, leading to a revolution in fiber optic cables. The other half of the prize was shared by two researchers at Bell Labs, Willard S. Boyle and George E. Smith, for inventing the semiconductor sensor known as a charge-coupled device, or CCD for short. CCDs now fill digital cameras by the millions.

The prize will be awarded in Stockholm on Dec. 10.

Key Cancer Spread Gene Found

From The BBC:

Scientists have pinpointed a gene linked to more than half of all breast cancers.

The gene, NRG1 (neuregulin-1), is also thought to play a role in many bowel, prostate, ovarian and bladder tumours.

The University of Cambridge team said the breakthrough should provide "vital information" about how cancer spreads.

Experts agreed the finding, published in the journal Oncogene, could represent a very significant advance in the fight against cancer.

Roman Coin Hoards Show More War Means Fewer Babies

From Wired Science:

Coins buried by anxious Italians in the first century B.C. can be used to track the ups and downs of the Roman population during periods of civil war and violence.

In times of instability in the ancient world, people stashed their cash and if they got killed or displaced, they didn’t come back for their Geld. Thus, large numbers of coin hoards are a good quantitative indicator of population decline, two researchers argue in in the Proceedings of the National Academy of Science Monday.

Another fast ball... how predictable (Image: Rex Features)

From New Scientist:

A clever athlete knows how to keep an opponent guessing, but professionals act more predictably than they should. So says a study based on game theory, which shows that baseball pitchers throw too many fastballs and American football teams don't pass the ball enough. The finding could give savvy teams an extra victory or two over the course of a season.

The game theory concept of "minimax" says that players in a head-to-head match should follow two basic rules: first, play in a way that minimises your opponent's possible gain; second, be unpredictable.

Baby Mammoth Yields Secrets After 40,000 Years In Siberian Tundra

From Times Online:

A baby woolly mammoth that died after being sucked into a muddy river bed 40,000 years ago has revealed more prehistoric secrets of how the species survived in its icy habitat.

The mammoth, known as Lyuba, was about a month old when she died in the Siberian tundra, where she remained until she was discovered by reindeer herders three years ago. Her body was so well preserved in the permafrost that her stomach retained traces of her mother’s milk, and scientists identified sediment in her mouth, trunk and throat — suggesting that she suffocated while struggling to free herself from the mud.

From MSNBC:

The moon, so bright and large in the sky compared to other celestial objects, has captured the attention of humans at least since the dawn of consciousness. Over these eras, mankind's view of the moon has evolved, from the more mystical image of it as a god, to the thought it was covered in seas and vegetation. Most recently, it's been viewed as a dry and dusty wasteland.

Recent findings of water on the lunar surface could spur yet another shift in the way we see our orbiting companion.

The moon appears in early art thousands of years ago, showing that early man was as enthralled by its eerie glow as later philosophers and scientists.

Gene Controlling Number Of Brain Cells Pinpointed

From Science Daily:

Science Daily (Oct. 5, 2009) — In populating the growing brain, neural stem cells must strike a delicate balance between two key processes – proliferation, in which the cells multiply to provide plenty of starting materials – and differentiation, in which those materials evolve into functioning neurons.

If the stem cells proliferate too much, they could grow out of control and produce a tumor. If they proliferate too little, there may not be enough cells to become the billions of neurons of the brain. Researchers at the University of North Carolina at Chapel Hill School of Medicine have now found that this critical balance rests in large part on a single gene, called GSK-3.

Mammoth Black Holes Push Universe To Its Doom

Speaking of black holes, what could be stranger?
Beyond a black hole's gravitational border -- or event horizon -- neither matter nor light can escape. Astrophysicists think dying stars about three to 20 times the mass of the sun can form these strange objects. At the center of galaxies, black holes about 10,000 to 18 billion times heavier than the sun are thought to exist, enlarged by gobbling up gas, dust, stars and small black holes.
What about mid-sized types? Perhaps surprisingly, evidence is both scarce and questionable for their existence.

From New Scientist:

THE mammoth black holes at the centre of most galaxies may be pushing the universe closer to its final fade-out. And it is all down to the raging disorder within those dark powerhouses.

Disorder is measured by a quantity called entropy, something which has been on the rise ever since the big bang. Chas Egan and Charles Lineweaver of the Australian National University in Canberra used the latest astrophysical data to calculate the total entropy of everything in the universe, from gas to gravitons. It turns out that supermassive black holes are by far the biggest contributors to the universe's entropy. Entropy reflects the number of possible arrangements of matter and energy in an object. The number of different configurations of matter a black hole could contain is staggering because its internal state is completely mysterious.

Mitochondrial Death Channels

Figure 1. A 53-year-old patient experiencing sporadic discomfort undergoes a coronary angiogram. The results are ominous. Severe stenosis (narrowing) is visible in the pinched regions (top middle), indicating the buildup of fatty deposits within the artery. If a wandering clot blocks the pinhole opening of a nearly clogged vessel, a heart attack ensues. With bloodflow blocked, cardiac cells downstream are starved for oxygen, leading to drastic metabolic changes as the cells struggle to survive. The most important changes affect mitochondria, the powerhouses of cell metabolism. The inset shows mitochondria (orange) arrayed among cardiac muscle fibrils (blue), where they are positioned to supply a steady stream of ATP to contracting muscle. Under oxidative stress, the mitochondria can also release potent effectors that lead directly to apoptosis—cell suicide. The trigger for the opening of the so-called mitochondrial death channels is, ironically, the return of oxygen to starved tissue during reperfusion. Learning to control the activities of the death channels could vastly improve the outlook for heart attack victims.

Top image by Zephyr/Photo Researchers, Inc.; bottom image by Steve Gschmeissner/Photo Researchers, Inc.

From American Scientist:

In heart attacks, cells die if they aren’t perfused with fresh oxygen—and kill themselves if they are. Understanding cell suicide may greatly improve outcomes.

Coronary artery disease is the leading cause of morbidity and mortality in North America and Europe. More than 12 million people in the United States have coronary artery disease, and more than 7 million have had a myocardial infarction (heart attack). Chronic stable angina (chest pain) is the initial manifestation of coronary artery disease in approximately half of all presenting patients, and about 16.5 million Americans (more than 5 percent) currently have stable angina.

India's Thirst Is Making Us All Wet

From New Scientist:

ONE nation's thirst for groundwater is having an impact on global sea levels. Satellite measurements show that northern India is sucking some 54 trillion litres of water out of the ground every year. This is threatening a major water crisis and adding to global sea level rise.

Virendra Tiwari from the National Geophysical Research Institute in Hyderabad, India, and colleagues used gravity data from the GRACE satellite to monitor the loss of continental mass around the world since 2002. Regions where water is being removed from the ground have less mass and therefore exert a smaller gravitational pull on the satellite.

It was not entirely clear why it was not prolonged at the time or whether any human cloning experiments had been carried out in Russia during the past two years.

From Science Daily:

ScienceDaily (Oct. 3, 2009) — In 1980, Luis Alvarez and his collaborators stunned the world with their discovery that an asteroid impact 65 million years ago probably killed off the dinosaurs and much of the the world's living organisms. But ever since, there has been an ongoing debate about how long it took for life to return to the devastated planet and for ecosystems to bounce back.

Lamp Runs On Human Blood

A lamp that uses blood to create light is meant to make people rethink how they use energy. The lamp contains luminol, a chemical that reacts with the iron in blood and creates a bright blue glow. Credit: Mike Thompson, http://www.miket.co.uk/

From Live Science:

What if, every time you wanted to switch on a light, you had to bleed? Would you think twice before illuminating the room, and in turn, using up energy?

That's the idea behind the blood lamp, invented by Mike Thomspon, an English designer based in The Netherlands. The lamp contains luminol – the same chemical forensic scientists use to check for traces of blood at a crime scence. Luminol reacts with the iron in red blood cells and creates a bright blue glow.
To use the lamp, you first need to mix in an activating powder. Then, you break the glass, cut yourself, and drip blood into the opening.

From ABC News (Australia):

The NASA Viking 2 probe, which landed on Mars in 1976, may have come within centimetres of finding water three decades before it was eventually found.

The finding could result in scientists re-evaluating data collected by the spacecraft, which was sent to look for signs of life on the red planet.

"Oh my, oh my," says retired Viking scientist Dr Patricia Straat.
