Female Wild Horses Stick Together
From Live Science:
Wild mares that form strong social bonds with other mares produce more foals than those that don’t, researchers have found, in what may be the first documented link between “friendship” and reproductive success outside of primates.
The study followed bands of feral horses in the Kaimanawa Mountains of New Zealand over the course of three years. Elissa Z. Cameron, now at the University of Pretoria in South Africa, and two colleagues computed sociality scores for 56 mares, based on parameters such as the proportion of time each animal spent near other mares and the amount of social grooming she did.

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 MontaƱez.
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.

Michael Jackson Planned 'Robot Duplicate' Of Himself
From Register:
Dead megastar droid zombie blueprints offered for $1m.
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".

Mini Ice Age Took Hold Of Europe In Months
From New Scientist:
JUST months - that's how long it took for Europe to be engulfed by an ice age. The scenario, which comes straight out of Hollywood blockbuster The Day After Tomorrow, was revealed by the most precise record of the climate from palaeohistory ever generated.
Around 12,800 years ago the northern hemisphere was hit by the Younger Dryas mini ice age, or "Big Freeze". It was triggered by the slowdown of the Gulf Stream, led to the decline of the Clovis culture in North America, and lasted around 1300 years.

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.

The Giant Iceberg That Went Walkabout... Towards The Coast Of Australia
Should that be there? A giant iceberg is seen off Macquarie Island which lies halfway between Antarctica and Australia. Scientists say it is unusual to see one so far north
From The Daily Mail:
Australia is known for sunny beaches, surfers, and blistering Outback heat.
So scientists were a bit taken aback when they spotted this giant iceberg floating near an island Down Under.
Australian Antarctic Division researchers were working on Macquarie Island when they first saw the iceberg last Thursday about about five miles off the island. It is rare to see an iceberg floating so far north of Antarctica, researchers said.

Apec Leaders Drop Climate Target
From The BBC:
World leaders meeting in Singapore have said it will not be possible to reach a climate change deal ahead of next month's UN conference in Denmark.
After a two-day Asia-Pacific summit, they vowed to work towards an "ambitious outcome" in Copenhagen.
But the group dropped a target to halve greenhouse gas emissions by 2050, which was outlined in an earlier draft.

Army Corps of Engineers Now Required to Consider Climate Change in All Future Projects
From Popular Science:
Worst-case planning never hurt anybody, and certainly not federal water projects that cost millions of dollars and could be easily undone by climate change and rising sea levels. A new policy now requires the U.S. Army Corps of Engineers to plan for future climate change when designing plans for flood control or other projects.

From Scientific American:
The "new energy" economy rolls forward even as hopes for an international deal to combat climate change at Copenhagen shift into reverse.
BRIGHTON, Colo. - The low-carbon economy has already arrived on the windy prairie north of this fast-growing Denver 'burb. It's here that Danish wind-turbine giant Vestas converted 298 acres of hayfield into the West's largest turbine factory - and turned Brighton into a magnet for "green" energy companies.
It's part of a $1 billion investment by the company in the United States, what Colorado Gov. Bill Ritter touts as a "new energy economy."

Watch A 2006 Bugatti Veyron Crash On Video
2006 Bugatti Veyron Crashes On Video, Posted To Facebook -- Christian Science Monitor
Facebook video of a 2006 Bugatti Veyron crash shows the car making a wall of water as it hits a Texas lagoon. No one was injured in the crash.
It’s one of the rarest cars on the road, and Galveston, Tex. medical school student Joe Garza saw it crash on his way to get groceries.
He and a friend were driving off of Galveston Island when they pulled up alongside the $2 million French supercar, believed to be one of just 15 in the US. When they pulled up to the sporty two-seater, Garza whipped out his camera and started shooting. That’s when the unthinkable happened.

Cocaine And Pepper Spray – A Lethal Mix?
From New Scientist:
DEATHS in US police custody during the early 1990s may have been the result of an interaction between capsaicin, the key ingredient in pepper sprays, and psychostimulant drugs, an experiment in mice suggests.
If the two have a fatal interaction in people then police forces might have to rethink their use of pepper spray as a non-lethal weapon, says John Mendelson of the Addiction and Pharmacology Research Laboratory at St Luke's Hospital in San Francisco, who led the mouse research.

From Watts Up With That?
From the “WUWT never reports on anything warm department”, JPL reports El NiƱo looks like it is on schedule to make a Christmas appearance as “The Boy”. The good news is that it will likely help California’s water situation this year.
From NASA Jet Propulsion Laboratory
El NiƱo is experiencing a late-fall resurgence. Recent sea-level height data from the NASA/French Space Agency Ocean Surface Topography Mission/Jason-2 oceanography satellite show that a large-scale, sustained weakening of trade winds in the western and central equatorial Pacific during October has triggered a strong, eastward-moving wave of warm water, known as a Kelvin wave.

Rat Made Supersmart -- Similar Boost Unsafe in Humans?
Scientists have tripled the memory of a rat named Hobbie-J (not pictured) by enhancing a single gene, suggesting that similar therapies may someday aid—or bedevil—humans, according to an October 2009 study. Photograph by Vincent J. Musi, National Geographic Stock
From National Geographic:
By modifying a single gene, scientists have made Hobbie-J the smartest rat in the world, a new study says.
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.

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.
