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.

Egypt To Apply For First Arabic-Alphabet Internet Domain Name

From CTV News/AP:

SHARM EL-SHEIK, Egypt — Egypt will apply for the first Internet domain written in Arabic, its information technology minister said Sunday at a conference grouping Yahoo's co-founder and others to discuss boosting online access in emerging nations.

Tarek Kamel said Egypt on Monday would apply for the new domain -- pronounced ".masr" but written in the Arabic alphabet -- making it the first Arab nation to apply for a non-Latin character domain. The effort is part of a broader push to expand both access and content in developing nations, where the Internet remains out of reach for wide swaths of the population.

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

Scence from 2012 courtesy of Columbia Tristar Marketing Group

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.

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

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.

California Droughts When Planet Warms?

From Future Pundit:

Why worry about earthquakes when we can worry about massive droughts instead?

California experienced centuries-long droughts in the past 20,000 years that coincided with the thawing of ice caps in the Arctic, according to a new study by UC Davis doctoral student Jessica Oster and geology professor Isabel Montañez.

The finding, which comes from analyzing stalagmites from Moaning Cavern in the central Sierra Nevada, was published online Nov. 5 in the journal Earth and Planetary Science Letters.

Global warming gets a lot of attention due to the prospects of huge low lying areas getting submerged. But big changes in regional climate - whether human caused or not - seem much more interesting to me. Such changes could occur at any time.

From Time Magazine:

This month, the journal Nature Geoscience published a study calculating that deforestation is responsible for about 15% of global carbon emissions, down from earlier estimates of 20% or more. Most of the world's deforestation is concentrated in a few tropical nations, like Brazil and Indonesia where trees are disappearing fast — when these trees die or are burned, they release into the atmosphere all the carbon they've sucked up while they were alive. According to the Nature Geoscience study, the problem of deforestation is becoming a lot less dire than previously thought.

Telegraph.co.uk At 15: Making The News

From The Telegraph:

The machinery for putting the news online has changed a lot in the 15 years that Telegraph.co.uk has been live, says Ian Douglas.

In the summer of 1999, when the web was nine years old, the Telegraph's website was almost five and I arrived at Canary Wharf for my first shift. Newcomers were paired with someone with more experience to learn the ropes.

Check the text, paste some tags in here and here, add links to the bottom of the page, then send it off, I was told. 'Send it off where,' I asked. 'To Overlord,' was the ominous reply. Overlord was the batch process built by Tim Brown, architect of the early online Telegraph efforts. Tim was usually to be found cropping photographs in the corner on night shifts, but two years before I arrived he had built the newspaper's first web content management system in his spare time. Overlord took the stories that had been worked on throughout the evening and turned them into web pages to be published on a server sitting in a cupboard a few doors down.

There Is More Water On The Moon Than What We Thought

Lunar Impactor Finds Clear Evidence Of Water Ice On Moon -- Wired Science

There is water on the moon, NASA confirmed today, and lots of it.

In the first look at results from the LCROSS mission, which sent a probe crashing into the Cabeus crater near the moon’s south pole, NASA’s main investigator said their instruments clearly detected water, despite the underwhelming plume.

Within the field of view of their instruments, the team measured approximately 220 pounds or about 26 gallons of water. Next, the team will try to understand how the compounds they saw in the plume relate to what’s actually embedded in the lunar regolith at the bottom of the permanently shadowed crater.

An obscure group of scorpionflies with specialized mouthparts may have pollinated ancient plants millions of years before flowers evolved, a new study suggests.

Fossils indicate that before flowers evolved about 130 million years ago, most plants with seeds were wind-pollinated. Yet the pollen grains of some plants that lived in the prefloral era were too big to be wind-dispersed, say Conrad Labandeira, a paleoentomologist at Smithsonian Institution’s National Museum of Natural History in Washington, D.C. Also, he notes, pollen receptors were hidden deep within some of those plants and wouldn’t have been readily exposed to windborne pollen.

From Science Daily:

Science Daily (Nov. 13, 2009) — When Europe's comet chaser Rosetta swings by Earth on Nov. 13 for a critical gravity assist, tracking data will be collected to precisely measure the satellite's change in orbital energy. The results could help unravel a cosmic mystery that has stumped scientists for two decades.

Since 1990, scientists and mission controllers at ESA and NASA have noticed that their spacecraft sometimes experience a strange variation in the amount of orbital energy they exchange with Earth during planetary swingbys. The unexplained variation is noticed as a tiny difference in speed gained or lost during the swingby when comparing that predicted by fundamental physics and that actually measured after the event.

Friday The 13th: Your Luck Is About To Change

From Live Science:

If Friday the 13th is unlucky, then 2009 has been an unusually unlucky year. But your luck is about to change. Today is the last of three Friday the 13ths you'll have to endure this year.

The other two were in February and March. Such a rare triple-threat occurs only once every 11 years.

The origin of the link between bad luck and Friday the 13th is murky. The whole thing might date to Biblical times (the 13th guest at the Last Supper betrayed Jesus). By the Middle Ages, both Friday and the number 13 were considered bearers of bad fortune. In modern times, the superstition permeates society.

Tiny Mutation Led To Human Speech

Human speech is thought to have emerged 100,000 to 200,000 years ago, some five million years after chimps and humans took divergent paths on the tree of evolution. Photo: iStockphoto

From Cosmos:

PARIS: Two minute evolutionary changes in a gene that is otherwise identical in humans and chimps could explain why we have fully fledged power of speech while other primates do not.

The findings may also point to new drug targets for hard-to-treat diseases that disrupt speech, such as schizophrenia and autism, said a study detailed in the British journal Nature today.

Behind The CDC's Soaring H1N1 Death Totals

From Time Magazine:

The Centers for Disease Control and Prevention (CDC) released on Thursday updated estimates of the number of H1N1 infections and deaths in the U.S. According to the new figures, about 4,000 Americans, including 540 children, have died of H1N1 flu, and 2 million people have been infected since April, when the novel flu virus first surfaced. The new death toll, which encompasses data through Oct. 17, represents a tripling of CDC estimates issued just last week; the number of deaths in children quadruples last week's figures. But the increase does not mean that the disease has suddenly become more deadly or severe, according to health officials, who say they are not surprised by the higher numbers.

Undercurrent Of Doubt Over Electric Motors

A loophole in EU targets on cutting CO2 emissions means that the more electric cars are produced, the more SUVs manufacturers can sell. Reuters

From The Independent:

Greener power generation needed if electric vehicles are really to reduce emissions.

Electric cars , which emit no carbon dioxide from their tailpipe, are not the answer some people think they are to environmental transport problems, a new report claims today.

The idea that a wholesale switch to electric transport would automatically reduce CO2 emissions and dependence on oil is a myth, says the analysis prepared for the Environmental Transport Association (ETA).
