The human brain: Detective of auditory and visual change
The human brain is capable of detecting the slightest visual and auditory changes. Whether it is the flash of a student’s hand into the air or the faintest miscue of a flutist, the brain instantaneously and effortlessly perceives changes in our environment.

New buffer resists pH change, even as temperature drops
Researchers at the University of Illinois have found a simple solution to a problem that has plagued scientists for decades: the tendency of chemical buffers used to maintain the pH of laboratory samples to lose their efficacy as the samples are cooled.

The River That Raised a Mountain
If you think erosion always wears down mountains, think again. Researchers now report a case in which a river created a new mountain, a dramatic example of how climate, plate tectonics, and erosion can affect each other.

Nuclear war: the threat that never went away
In the first of a series of articles covering nuclear issues, Declan Butler looks at the nuclear non-proliferation treaty and finds that there has never been a better climate for negotiation.

Climate worries complicate Alaska drilling plan
A controversial proposal to extract vast supplies of oil and gas from Alaska's outer continental shelf pits America's energy needs against environmental protection. Unlike similar clashes in the past, there's a complicating factor this time: global warming.

Warming Autumns May Hinder Plants' Climate-Cooling Role
As Earth warms and seasons shift, plants may become less efficient at keeping a greenhouse gas out of the atmosphere, a new study suggests.

Climate Pollution From Aviation Increasing
EU environment ministers have failed to seize a key opportunity to curb emissions from the aviation sector through the European Emissions Trading Scheme (ETS), WWF said at the conclusion of the EU Environment Council in Brussels.

'Drilling Up' Into Space for Energy
While great nations fretted over coal, oil and global warming, one of the smallest at the U.N. climate conference was looking toward the heavens for its energy.

The Doh! of technology
Every researcher knows the best plans can go horribly pear-shaped. Just think of the ill-fated Beagle 2 spacecraft that went missing on its way down to the surface of Mars just four years ago. What exactly went wrong is still unclear, but a mechanical fault with the landing parachute is the chief suspect. And remember the Mars Climate Orbiter, which smacked into the Red Planet's surface?

Evolution tied to Earth movement
Scientists long have focused on how climate and vegetation allowed human ancestors to evolve in Africa. Now, University of Utah geologists are calling renewed attention to the idea that ground movements formed mountains and valleys, creating environments that favored the emergence of humanity.

Congress Fails Science
The U.S. Congress has long been a slow and irresolute institution, especially when it comes to science issues. Unfortunately, the Democratic majority that came to power in the 2006 midterm election has so far done little to change that reputation.

Study links success of invasive Argentine ants to diet shifts
The ability of Argentine ants to change from carnivorous insect eaters to plant sap-loving creatures has helped these invasive social insects rapidly spread throughout coastal California, according to a new study, displacing many native insects and creating ant infestations familiar to most coastal residents.

A 40-Hour Laptop Battery?
Although improvements in laptop computers and other electronics continue at a torrid pace, the batteries that power them have made only modest strides in recent years. A new advance in nanotechnology could change all that. Lithium ion batteries made with tiny whiskers of silicon can store as much as 10 times the charge of conventional rechargeables, researchers report

Beetle of Many Colors
Near the summit of Cerro Galera in Panama lives a golden beetle that can turn itself brick red in under two minutes. While other bugs may change color due to external circumstances like temperature, the Panamanian tortoise beetle is one of the few creatures known to control its own color changing. The beetle’s secret? It can alter the flow of fluid in its exoskeleton, scientists recently revealed.

25 Surprising and Simple Tips for a Greener Life
Conservation isn’t sexy, it’s not fun and changing bulbs, turning down the thermostat or stuffing insulation, doesn’t seem like it will change the world. But it doesn’t cost much of anything, it’s easy and, yes, diminishing the impact you have on the world will make a difference. Follow these 25 tips for a cheaper, more efficient and, of course, greener life.
