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.

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 TomorrowFrom 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.

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.

From Register:

Famous dead pop legend Michael Jackson intended to construct an eerily-lifelike robotic duplicate of himself, according to reports. Detailed three-dimensional scans of the deceased globo-celeb's body were made, and the super-accurate body maps are now said to be on sale for a million dollars.
The story was reported yesterday by the Daily Star, which says that the occasionally troubled dead overlord of pop had the scans made in 1996 "in a bizarre bid to build a robot twin... [Unidentified] scientists say following his death on June 25, the eerie images could be used to bring him back".

Overlord was the batch process built by Tim Brown, architect of the early online Telegraph efforts.
