Wind Farms Can Affect Local Weather Patterns
From The BBC:
Wind farms, especially big ones, generate turbulence that can significantly alter air temperatures near the ground, say researchers.
As turbines often stand on agricultural land, these changes could in turn affect crop productivity.
In the journal Proceedings of the National Academy of Sciences (PNAS), the team says the impact could be reduced by changing rotor design.
Another option would be to site farms in areas with high natural turbulence.

Stuxnet: Fact Vs. Theory
From CNET:
The Stuxnet worm has taken the computer security world by storm, inspiring talk of a top secret, government-sponsored cyberwar, and of a software program laden with obscure biblical references that call to mind not computer code, but "The Da Vinci Code."
Stuxnet, which first made headlines in July, (CNET FAQ here) is believed to be the first known malware that targets the controls at industrial facilities such as power plants. At the time of its discovery, the assumption was that espionage lay behind the effort, but subsequent analysis by Symantec uncovered the ability of the malware to control plant operations outright, as CNET first reported back in mid-August.

The Language That Lovers Share Is A 'Window' Into The State Of Their Relationship
From The Telegraph:
Couples develop their own language of love that ebbs and flows depending on the state of their relationship, scientists believe.
Those deeply in love speak and write alike, mimicking and repeating words and phrases that each other use.
But if the relationship sours then the common language breaks down and they begin to sound more like strangers again.

From Science Daily:
ScienceDaily (Oct. 1, 2010) — It might seem obvious that a dinosaur's leg bone connects to the hip bone, but what came between the bones has been less obvious. Now, researchers at the University of Missouri and Ohio University have found that dinosaurs had thick layers of cartilage in their joints, which means they may have been considerably taller than previously thought. The study is being published this week in the journal PLoS ONE (Public Library of Science).

Instant Expert: Rebuilding Human Minds
Memory Lost, Memory Gained koppillustration.com
From Popular Science:
Scientists hope to strengthen aging brains by tweaking the behavior of DNA.
Age-related memory loss—the kind where you remember friends from decades ago but can’t remember your grandchildren—is largely a mystery, but a class of com-pounds used to treat cancer has given neuroscientists clues to its molecular underpinnings. Scientists also suspect that the compounds responsible for this insight, called histone deacetylase inhibitors, could significantly slow memory loss—perhaps for years. (Two drugs used now to treat memory loss and Alzheimer’s disease work only for a short time.)

The Slippery Slope To Obesity
From New Scientist:
REWARD pathways in the brains of overweight people become less responsive as they gain weight. This causes them to eat more to get the same pleasure from their food, which in turn reduces the reward response still further.
Eric Stice, a psychologist at the University of Texas at Austin, and colleagues used fMRI brain scans to monitor 26 obese or overweight volunteers as they sipped either a tasty milkshake or a flavourless liquid resembling saliva. They compared the effect of both drinks on brain activity in the dorsal striatum, a key part of the brain's reward circuitry. Six months later, they retested the volunteers.

Dolphin Species Attempt 'Common Language'
From The BBC:
When two dolphin species come together, they attempt to find a common language, preliminary research suggests.
Bottlenose and Guyana dolphins, two distantly related species, often come together to socialise in waters off the coast of Costa Rica.
Both species make unique sounds, but when they gather, they change the way they communicate, and begin using an intermediate language.
That raises the possibility the two species are communicating in some way.

Best Of The Ig Nobel Prizes 2010
From New Scientist:
Are the Ig Nobels losing their edge? The venue for this year's ceremony honouring science that "makes you laugh, then makes you think" was Harvard's Sanders Theater – a splendidly sober Victorian building that's housed many dignified graduations and historic lectures. The capacity audience was permitted to throw paper airplanes only during two designated intervals, rather than whenever the fancy took them. And the first cash prizes in the awards' 20-year history raised the ugly suspicion that the Ig Nobels will become yet another awards ceremony that's all about money.

Finding E.T. May Become Harder If Aliens Go Digital
From Space.com:
Scientists may have an extra challenge when it comes to detecting alien civilizations: a time limit.
A new study suggests that intelligent aliens, if their technological progression is similar to that of humanity's, are likely to have moved away from noisy radio transmissions to harder-to-hear digital signals within a 100-year time frame. That offers Earth just a narrow window in which to pick up any signals from extraterrestrial civilizations.

It's cold, dusty, and bereft of planets, but the outskirts of our solar system are anything but dull, according to increasing evidence from NASA's Interstellar Boundary Explorer (IBEX) craft.
As charged particles flow out from the sun, they eventually bump up against interstellar medium—the relatively empty areas between stars. These interactions "inflate" a protective bubble that shields Earth and the entire solar system from potentially harmful cosmic rays (solar system pictures).

Industrial computer systems are typically far less secure than they should be, experts say.
For the last few months, a sophisticated computer worm has wriggled its way between some of the most critical control systems in the world.
The timing of the worm's release, combined with several clues buried in its code, has led some experts to speculate that the worm, dubbed Stuxnet, was originally designed to sabotage an Iranian nuclear facility, possibly the enrichment plant in Natanz, roughly 180 miles south of Tehran. This week, officials in Iran confirmed that Stuxnet had been found on systems inside the plant, although they denied that it had caused any harm.

The Supernova's Secrets Cracked At Last?
From Time Magazine:
Most stars end their lives in a whimper — our own sun will almost certainly be one of them — but the most massive stars go out with an impressive bang. When that happens, creating what's known as a Type II supernova, the associated blast of energy is so brilliant that it can briefly outshine an entire galaxy, give birth to ultra-dense neutron stars or black holes, and forge atoms so heavy that even the Big Bang wasn't powerful enough to create them. If supernovas didn't exist, neither would gold, silver, platinum or uranium. The last time a supernova went off close enough to earth to be visible without a telescope, back in 1987, it made the cover of TIME.

Capping nearly a year of intense industry turmoil, agency uncertainty and congressional debate, the vote reflected last-minute decisions by House leaders from both parties to embrace a previously-passed Senate blueprint for NASA, though it doesn't completely satisfy any of the rival interest groups or regional factions maneuvering to shape the agency's future.

Did UFOs Disarm Nuclear Weapons? And If So, Why? -- Live Science
At an unusual press conference recently held in Washington, D.C., a UFO author and a half-dozen or so former U.S. military airmen asserted that "The U.S. Air Force is lying about the national security implications of unidentified aerial objects at nuclear bases and we can prove it." They claim that since 1948, extraterrestrials in spaceships have not only been visiting Earth but hovering over British and American nuclear missile sites and temporarily deactivating the weapons.

Stonehenge Boy 'Was From The Med'
From The BBC:
Chemical tests on teeth from an ancient burial near Stonehenge indicate that the person in the grave grew up around the Mediterranean Sea.
The bones belong to a teenager who died 3,550 years ago and was buried with a distinctive amber necklace.
The conclusions come from analysis of different forms of the elements oxygen and strontium in his tooth enamel.
Analysis on a previous skeleton found near Stonehenge showed that that person was also a migrant to the area.
