From Science Daily:

Science Daily (Nov. 15, 2009) — A number of U.S. states now use facial recognition technology when issuing drivers licenses. Similar methods are also used to grant access to buildings and to verify the identities of international travelers. Historically, obtaining accurate results with this type of technology has been a time intensive activity. Now, a researcher from the University of Miami College of Engineering and his collaborators have developed ways to make the technology more efficient while improving accuracy.

Surprising Discovery Explains Formation Of New Memories

From U.S. News And World Report:

Short-term memory may depend in a surprising way on the ability of newly formed neurons to erase older connections. That's the conclusion of a report in the November 13th issue of the journal Cell, a Cell Press publication, that provides some of the first evidence in mice and rats that new neurons sprouted in the hippocampus cause the decay of short-term fear memories in that brain region, without an overall memory loss.

Time-Travelling Browsers Navigate The Web's Past

19 October 1996: Plane maker Boeing had what was,
for the time, a very image-intensive home page

From New Scientist:

Finding old versions of web pages could become far simpler thanks to a "time-travelling" web browsing technology being pioneered at the Los Alamos National Laboratory in New Mexico.

Bookmarking a page takes you to its current version – but earlier ones are harder to find (to see an award-winning 1990s incarnation of newscientist.com, see our gallery of web pages past, right). One option is to visit a resource like the Internet Archive's Wayback Machine. There, you key in the URL of the site you want and are confronted with a matrix of years and dates for old pages that have been cached. Or, if you want to check how a Wikipedia page has evolved, you can hit the "history" tab on a page of interest and scroll through in an attempt to find the version of the page on the day you're interested in.

Last Ice Age Took Just SIX Months To Arrive

Photo: Climate catastrophe: Rapid climate change was the subject of the Hollywood blockbuster The Day After Tomorrow

From The Daily Mail:

It took just six months for a warm and sunny Europe to be engulfed in ice, according to new research.

Previous studies have suggested the arrival of the last Ice Age nearly 13,000 years ago took about a decade - but now scientists believe the process was up to 20 times as fast.

In scenes reminiscent of the Hollywood blockbuster The day After Tomorrow, the Northern Hemisphere was frozen by a sudden slowdown of the Gulf Stream, which allowed ice to spread hundreds of miles southwards from the Arctic.

Geological sciences professor William Patterson, who led the research, said: 'It would have been very sudden for those alive at the time. It would be the equivalent of taking Britain and moving it to the Arctic over the space of a few months.'

Starvation 'Wiped Out' Giant Deer

From The BBC:

The giant deer, also known as the giant Irish deer or Irish elk, is one of the largest deer species that ever lived.

Yet why this giant animal, which had massive antlers spanning 3.6m, suddenly went extinct some 10,600 years ago has remained a mystery.

Now a study of its teeth is producing tantalising answers, suggesting the deer couldn't cope with climate change.

As conditions became colder and drier in Ireland at the time, fewer plants grew, gradually starving the deer.

The discovery is published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology.

From Technology Review:

Carbon dioxide captured from power plants could make geothermal energy more practical.

Carbon dioxide generated by power plants may find a second life as a working fluid to help recover geothermal heat from kilometers underground. Such a system would not only capture the carbon dioxide and keep it out of the atmosphere, it would also be a cost-effective way to use the greenhouse gas to generate new power.

In the peaks and valleys of California’s wine country, vinters remember the region’s rich history and rebuild for the future

Atop Howell Mountain, one of the peaks that frame California’s wine-soaked Napa Valley, the towering groves of ponderosa pines are home to one of the region’s legendary ghost wineries. Born in the late 1800s, killed off by disease, disaster, depression, and denial in the early 20th century, and then laid to solemn rest for decades, La Jota Vineyard — like its countless sister specters found throughout the region — is once again living, breathing, and making world-class wine. And for those who care to listen, this resurrected winery has plenty to say about everything from America’s melting pot history and the long-celebrated quality of West Coast wine to strategies for sustainability and using the power of story to boost sales.

In A Malaria Hot Spot, Resistance To A Key Drug

From Time Magazine:

Every year, thousands of workers arrive at the sapphire and ruby mines of Pailin, Cambodia, risking their lives to unearth gems in the landmine-ridden territory. Soon, however, they could be the ones to put millions of others at risk. On the Thai-Cambodian border, a rogue strain of malaria has started to resist artemisinin, the only remaining effective drug in the world's arsenal against malaria's most deadly strain, Plasmodium falciparum. For six decades, malaria drugs like chloroquine and mefloquine have fallen impotent in this Southeast Asian border area, allowing stronger strains to spread to Burma, India and Africa. But this time there's no new wonder drug waiting in the wings. "It would be unspeakably dire if resistance formed to artemisinin," says Amir Attaran, a professor of law and medicine at the University of Ottawa who has written extensively on malaria issues.

Drink Culture: It's As Old As The Hills

From The New Scientist:

QUESTS don't come much more appealing than this. But while for most people the quest ends in the nearest bar, biomolecular archaeologist Patrick McGovern has gone much further. He has spent decades travelling the world and journeying back in time, scraping dirty crusts from ancient cauldrons, retrieving dribbles of liquid from sealed jars and extracting residues from the pores of prehistoric pots, all in the name of investigating the origins of ancient alcoholic beverages.

After he famously identified the world's oldest wine - a resinated grape wine found in two clay jars from the Neolithic village of Hajji Firuz in Iran, in 2004 he found an even older sample in China. At a 9000-year-old site called Jiahu on the banks of the Yellow river, he recovered the remains of grog made from rice, hawthorn fruit, grapes and honey. Another of his recent revelations is that the people of Central America got drunk on fermented chocolate, giving new meaning to the word chocoholic.

A similar gene tweak might boost human brainpower too, but scientists warn that there is such a thing as being too smart for your own good.

For years scientifically smartened rats have skittered through movies and books such as Flowers for Algernon and The Secret of NIMH. But Hobbie-J is anything but fiction.

From The Telegraph:

People who think science is dull are wrong. Here are 10 reasons why.

Physics is weird. There is no denying that. Particles that don’t exist except as probabilities; time that changes according to how fast you’re moving; cats that are both alive and dead until you open a box.

We’ve put together a collection of 10 of the strangest facts we can find, with the kind help of cosmologist and writer Marcus Chown, author of We Need To Talk About Kelvin, and an assortment of Twitter users.

Dinosaur Discovered In South Africa... And May Reveal How They Grew To Be So Big

Bridging the gap: A graphic released by Australian paleontologist Adam Yates shows the newly discovered dinosaur species - with the fossil bones found by the team marked on the outline

From The Daily Mail:

A new dinosaur named the 'Earth Claw' has been discovered in South Africa.

The discovery of the Aardonyx celestae marks a breakthrough in understanding how creatures began walking on all fours - and why they grew so large, scientists claimed yesterday.

Researchers believe the near-perfect skeleton bridges the gap between the earliest two-legged specimens and those who later walked on four limbs.

Humans Still Evolving As Our Brains Shrink

Weighing in at an average of 2.7 pounds (1,200 grams), the human brain packs a whopping 100 billion neurons. Every minute, about three soda-cans worth of blood flow through the brain. Credit: dreamstime.

From Live Science:

Evolution in humans is commonly thought to have essentially stopped in recent times. But there are plenty of examples that the human race is still evolving, including our brains, and there are even signs that our evolution may be accelerating.

Shrinking brains

Comprehensive scans of the human genome reveal that hundreds of our genes show evidence of changes during the past 10,000 years of human evolution.

From CNET News:

Medpedia, a collaborative project for medical information launched in February, is getting beyond the medical-data basics as it adds answers, alerts, and analysis.

Founded on the noble and semipractical system of providing free online medical information generated for and by physicians, journals, schools, patients, and more, Medpedia's three stated goals are to be collaborative, interdisciplinary, and transparent. The idea is to maximize knowledge and minimize the kind of screwing around that continually threatens the efficacy of other wiki-based projects. Of course, the extent to which this is successful hinges on the quality, integrity, and transparency of the editors.

Quantum 'Trampoline' To Test Gravity

From The New Scientist:

IT'S the world's smallest trampoline. Bouncing atoms with lasers could make ultra-precise measurements of gravity.

To test theories such as general relativity, the strength of gravity is measured precisely using ensembles of supercold atoms falling in a vacuum chamber. These ensembles are called "Bose-Einstein condensates".
