Why Web Widgets Will Invade Your TV
From The Christian Science Monitor:
Web widgets bring Internet perks to the biggest screen in most people’s homes.
The Internet revolution may finally be televised.
Innocuous little software applications, popularly known as “widgets,” may turn out to be the back door to your TV screen that Internet companies have been waiting for.
For more than a decade, businesses have been trying to make the Internet available on the largest screen in most homes. In 1996, Time Warner offered WebTV, which failed to find an audience and folded. Even today, projects like Hewlett Packard’s MediaSmart (2006) and Apple TV (2007) have yet to win over large numbers of viewers, hampered by complicated setups or limited programming choices.

Innovation: The Dizzying Ambition Of Wolfram Alpha
When the search engine Wolfram Alpha launched earlier this year, the interest was huge. Enticed by a well-oiled publicity machine, web users swamped the site and its servers were overwhelmed. Then everything went quiet – so quiet that it was easy to imagine that Alpha would follow countless Google wannabes to the great search engine directory in the sky.
That was to reckon without Stephen Wolfram, a physicist famous for creating and selling the mathematics software Mathematica and for his pioneering but controversial work on cellular automata.

Yahoo continues to lose share in the search market, as Google and Microsoft pick up the difference.
Comscore's measurement of the U.S. search market in October shows that Google--as usual--still dominates the search landscape. It now watches 65.4 percent of all searches pass through its servers, up 0.5 market share points from September of this year.
The Top 8 Dinosaur Discoveries of 2009
From Popular Mechanics:
Paleontologists have had a good year, bringing a slew of new dinosaurs to the books. We pored through the many finds to bring you the best horned, bird-footed, feathered and, of course, ferocious new dinosaurs unveiled this year.
In science, it's exceedingly rare when the naked eye usurps modern technology—powerful telescopes offer humans unprecedented views of celestial phenomena, surgeons can send tiny cameras inside your intestinal tract and even iPhone apps can spot public restrooms before you can. However, for the paleontologists who routinely discover new dinosaurs, a good set of eyes, geological know-how and a little luck remain the best tools.

Climate Change Gives Ancient Trees Growth Spurt
From The New Scientist:
Rising temperatures are causing some of the oldest trees on Earth to grow faster, new research suggests. But scientists are divided over whether or not the change will benefit the climate, as it may simply cause the trees to die more quickly.
Previous research (pdf) suggested that Great Basin bristlecone pines located in the mountains of western US are growing more rapidly. But the reason for the growth spurt – and whether or not it is unusual – was unclear.
Bacteria 'Glow Near Landmines'
From The Telegraph:
Bacteria that glow green in the presence of explosives could provide a cheap and safe way to find hidden landmines, according to British scientists.
The bugs can be mixed into a colourless solution that forms green patches when sprayed on to ground where mines are buried.
Researchers who created the bacteria at the University of Edinburgh believe the microbes could be dropped from the air on to danger areas.
Within a few hours, they would react to traces of explosives leaking from the devices buried underground.
Each year, between 15,000 and 20,000 people are killed or injured by landmines and unexploded ordnance, according to the charity Handicap International.

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
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
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
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.

The Ghost Wineries of Napa Valley
Napa Valley just north of St. Helena. Matt Kettmann
From The Smithsonian:
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 2012, Neutrinos Melt The Earth's Core, And Other Disasters
From Scientific American:
During an early screening of Roland Emmerich's latest disaster flick 2012, which opens today, laughter erupted in the audience near the end of the film thanks to corny dialogue and maudlin scenes (among the biggest guffaw getters: a father tries to reconnect with his estranged son on the telephone, only to have the son's house destroyed just before he could say anything). Nobody wants to take anything seriously in a movie like this, in which digital mayhem is the draw. But if it were an audience of physicists, the laughter probably would have started in the first five minutes. You can't take any of the science seriously, although I give the filmmakers credit for creativity.

Love and Envy Linked By Same Hormone, Oxytocin
From Science Daily:
Science Daily (Nov. 13, 2009) — A new study carried out at the University of Haifa has found that the hormone oxytocin, the "love hormone," which affects behaviors such as trust, empathy and generosity, also affects opposite behaviors, such as jealousy and gloating. "Subsequent to these findings, we assume that the hormone is an overall trigger for social sentiments: when the person's association is positive, oxytocin bolsters pro-social behaviors; when the association is negative, the hormone increases negative sentiments," explains Simone Shamay-Tsoory who carried out the research.

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
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.
Weekend Lie-Ins For Teenagers Wards Off Obesity
From The Telegraph:
Teenagers lying in at the weekend might seem like laziness, but it will actually help them stay slim and healthy, claim scientists.
New research suggests lazing in bed at the end of a busy week is just what children need to ward off obesity.
The scientists, who studied children aged five to 15, found those who slept in on Saturdays and Sundays were much less likely to have weight problems.
They believe the weekend snooze is crucial for school-age children to catch up on the sleep they miss out on during a busy week.
