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.

Eyes-On, Glasses Off, With Toshiba's Glasses-Less 3D TV
From CNN:
(CNET) -- Ceatec doesn't officially start until tomorrow, but Toshiba is already getting the lion's share of the buzz here on the show floor, with its Glasses-less 3D TV.
The device was announced last night, and people flocked to the demonstration in a dark makeshift theater today, where the wait was nearly an hour early this morning. The reason? Because finally, mercifully, a TV maker has come up with a way to watch 3D at home without those ridiculous plastic glasses.

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).

From Live Science:
After decades of apparent absence, bedbugs are back with a vengeance. The bugs have returned to U.S. cities, infesting hotels, schools, apartments, homes, stores and offices. The tiny bloodsuckers are known to leave red, itchy marks on their victims, as well as a social stigma.
But where did bedbugs come from, what harm do they really cause, and why the sudden resurgence?

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.)

Is This Apple Ap Going To Help Terrorists?
Threat: Security experts have slammed a £2 phone app which gives specific details about in-flight aircraft
Phone App That Tracks Planes 'Is Aid To Terrorists Armed With Missiles' - -The Daily Mail
A mobile phone application costing less than £2 which tracks the precise location of passenger aircraft in the sky is a serious terrorist threat and should be banned, according to a security expert.
The Plane Finder AR app for the Apple iPhone and Google’s Android allows users to point their phone at the sky and see the position, height and speed of nearby aircraft. It also shows the airline, flight number, departure point, destination and even the likely course.

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.

Mission To Search For Alien Life In Outer Atmosphere
From The Telegraph:
Life from outer space could be surviving on the outer fringes of the Earth's atmosphere, according to scientists who are to launch a mission to search for bacteria that could be living there.
In science fiction films the search for aliens involves travelling across the galaxy to planets millions of miles away.
But scientists believe they could be close to discovering alien life forms much closer to home – on the outer fringes of Earth's atmosphere.

Geology: A Trip To Dinosaur Time
From Nature News:
A project to drill a 10-kilometre-deep hole in China will provide the best view yet of the turbulent Cretaceous period. Jane Qiu reports.
The rock columns on the table are not much to look at. More than a metre long, 10 centimetres in diameter and mostly made up of oil shale and sandstone, they are a dull greyish green. But these, says Wang Chengshan, a geologist at the China University of Geosciences in Beijing, "are not ordinary rocks".

No Evidence for Clovis Comet Catastrophe, Archaeologists Say
From Science Daily:
ScienceDaily (Oct. 1, 2010) — New research challenges the controversial theory that an ancient comet impact devastated the Clovis people, one of the earliest known cultures to inhabit North America.
Writing in the October issue of Current Anthropology, archaeologists Vance Holliday (University of Arizona) and David Meltzer (Southern Methodist University) argue that there is nothing in the archaeological record to suggest an abrupt collapse of Clovis populations.

Americans' Sex Lives Exposed by New Survey
From Live Science:
Americans, on average, use a condom one in four times when they have vaginal sex, according to a recent survey that also finds men think women are having orgasms more than they are.
This new sex survey shows that condom use has increased among some groups, but promoting condom use – which prevents the spread of sexual transmitted diseases like AIDS – should remain a health priority, according to Michael Reece, the director of the Center for Sexual Health Promotion at Indiana University, which conducted the survey.
