From New Scientist:

The earthquake in Chile on Saturday was one of the biggest the world has felt in the past century – so why was the tsunami that spread across the Pacific smaller than originally feared?

The magnitude-8.8 earthquake was devastating, claiming at least 700 lives. Large tsunami waves were reported along parts of Chile's coastline: reports suggest the town of Constitución was worst affected by the wave.

Nose Scanning Techniques Could Sniff Out Criminals

Faces were analysed and mapped with a computer program

From The BBC:

We already have iris and fingerprint scanning but noses could be an even better method of identification, says a study from the University of Bath, UK.

The researchers scanned noses in 3D and characterised them by tip, ridge profile and the nasion, or area between the eyes.

They found 6 main nose types: Roman, Greek, Nubian, hawk, snub and turn-up.

Chile Quake Among Most Powerful Ever

From Discovery News:

The so-called megathrust quake that rocked the western coast of South America is the most powerful of its kind.

THE GIST:

* The 8.8-magnitude earthquake is similar to the 2004 Indian Ocean temblor that triggered devastating tsunamis.
* Called megathrusts, these quakes occur when one tectonic plate dives beneath another.
* The Chile tremor unleashed about 50 gigatons of energy.

The huge earthquake that struck off the coast of Chile belongs to an "elite class" of mega earthquakes, experts said, and is similar to the 2004 Indian Ocean temblor that triggered deadly tsunami waves.

A Bird's Eye View Of The Chile Earthquake's Energy Distribution

NOAA's Distributed Energy Map of the Chile Earthquake NOAA

From Popular Science:

It’s easy to think of tsunamis as phenomenon that mimic the behavior of ripples on the surface of water; you toss a stone into a pond and the resulting energy from the splash moves out away from the epicenter in a series of even, concentric circles. But this NOAA energy distribution map from the 8.8 magnitude earthquake in Chile over the weekend tells a different story.

Top 10 Spooky Sleep Disorders

From Live Science:

Sleep is supposed to be a time of peace and relaxation. Most of us drift from our waking lives into predictable cycles of deep, non-REM sleep, followed by dream-filled rapid-eye-movement (REM) sleep. But when the boundaries of these three phases of arousal get fuzzy, sleep can be downright scary. In fact, some sleep disorders seem more at home in horror films than in your bedroom.

From Discovery News:

A colossal head statue of King Tut's grandfather has been dug out in Luxor, Farouk Hosni, Egypt's Culture Minister, said Sunday.

Smoothly polished and perfectly preserved, the 2.5-meter (8-foot) head belonged to Amenhotep III, the pharaoh who was King Tutankhamun's grandfather, according to DNA tests revealed last week.

The ninth ruler of the Eighteenth Dynasty, Amenhotep III (1390-1352 B.C.), reigned for 38 year during a time when Egypt was at the height of prosperity and cultural development.

Suborbital Safety: Will Commercial Spaceflight Ramp Up the Risk?

From Popular Mechanics:

At the first-ever Next-Generation Suborbital Researchers Conference, high-level officials from NASA and the FAA addressed the risks that new private and commercial suborbital vehicles will carry when transporting NASA-sponsored payloads and personnel.

Ever since the loss of the space shuttle Challenger, almost a quarter of a century ago, the watchword above all others at NASA has been "safety." Unfortunately, watchwords don't necessarily create actual safety, as we learned a little over seven years ago, with the loss of her sister ship Columbia.

Stonehenge may have been surrounded by a "Stonehedge" that blocked onlookers from seeing secret rituals, according to a new study.

Evidence for two encircling hedges—possibly thorn bushes—planted some 3,600 years ago was uncovered during a survey of the site by English Heritage, the government agency responsible for maintaining the monument in southern England.

By Tracking Water Molecules, Physicists Hope To Unlock Secrets Of Life

Supercool. As individual water molecules fluctuate, breaking and forming bonds with their nearest neighbors, the result is slightly imperfect tetrahedral structures that are constantly in flux. Research suggests that these fluctuations give rise to some of water's most unusual and life-sustaining features. (Credit: Image courtesy of Rockefeller University)

From Science Daily:

Science Daily (Mar. 1, 2010) — The key to life as we know it is water, a tiny molecule with some highly unusual properties, such as the ability to retain large amounts of heat and to lose, instead of gain, density as it solidifies. It behaves so differently from other liquids, in fact, that by some measures it shouldn't even exist. Now scientists have made a batch of new discoveries about the ubiquitous liquid, suggesting that an individual water molecule's interactions with its neighbors could someday be manipulated to solve some of the world's thorniest problems -- from agriculture to cancer.

This Week’s Question: I live with my 40-year-old son and he smokes like the proverbial chimney around the house. I’m afraid of what it’s doing to his health. What can I do to get him to quit?

Tell him he may be killing you with his secondhand smoke.

Secondhand smoke—also called environmental tobacco smoke (ETS)—is made up of the “sidestream” smoke from the end of a cigarette, pipe, or cigar, and the “mainstream” smoke that is exhaled.

From Time Magazine:

If we're going to find a way to fix our long-term energy woes — whether it's through biofuels made from algae or through the rise of miniature nuclear-power plants, — the solution is likely to come from northern California. Yes, in Silicon Valley, the same entrepreneurs who brought us the Internet — and, O.K., Pets.com — are exploring new ways to make and use energy. And we'll need them, as much for our economy's well-being as for our planet's.

From The Guardian:

Ice broken off from Mertz glacier is size of Luxembourg and may decrease oxygen supply for marine life in the area.

An iceberg the size of Luxembourg that contains enough fresh water to supply a third of the world's population for a year has broken off in the Antarctic continent, with possible implications for global ocean circulation, scientists said today.

Happiness Ain't All It's Cracked Up To Be

From New Scientist:

The Founding Fathers liked happiness so much they considered pursuing it an inalienable right – but maybe that wasn't such a good idea. Happiness seems to make people more selfish, the latest in a series of revelations suggesting it changes how you think – and not in a good way.

Psychologist Joe Forgas at the University of New South Wales in Sydney, Australia, who has led many of these studies, suggests that happiness's negative effects all stem from a cheery mood's tendency to lull you into feeling secure. This makes you look inwards and behave both more selfishly and more carelessly.
