Pulsating Response to Stress in Bacteria Discovered
If the changing seasons are making it chilly inside your house, you might just turn the heater on. That's a reasonable response to a cold environment: switching to a toastier and more comfortable state until it warms up outside. And so it's no surprise that biologists have long thought cells would respond to their environment in a similar way.

Tropical Forests Fertilized by Nitrogen Air Pollution, Scientists Find
Scientists braved ticks and a tiger to discover how human activities have perturbed the nitrogen cycle in tropical forests. Studies at two remote Smithsonian Institution Global Earth Observatory sites in Panama and Thailand show the first evidence of long-term effects of nitrogen pollution in tropical trees.

Brain Cells Responsible for Keeping Us Awake Identified
Bright light arouses us. Bright light makes it easier to stay awake. Very bright light not only arouses us but is known to have antidepressant effects. Conversely, dark rooms can make us sleepy. It's the reason some people use masks to make sure light doesn't wake them while they sleep.

It Takes Two: Brains Come Wired for Cooperation, Neuroscientists Discover
When Nancy Grace and her partner danced a lively rumba to Spandau Ballet's 1980's hit, "True," on a recent "Dancing With the Stars," more was going on in the legal commentator's brain than worry over a possible wardrobe malfunction.

City Lights Could Reveal E.T. Civilization
In the search for extraterrestrial intelligence, astronomers have hunted for radio signals and ultra-short laser pulses. In a new paper, Avi Loeb (Harvard-Smithsonian Center for Astrophysics) and Edwin Turner (Princeton University) suggest a new technique for finding aliens: look for their city lights. "Looking for alien cities would be a long shot, but wouldn't require extra resources. And if we succeed, it would change our perception of our place in the universe," said Loeb.

Scientists Find Evidence of Ancient Megadrought in Southwestern U.S.
A new study at the University of Arizona's Laboratory of Tree-Ring Research has revealed a previously unknown multi-decade drought period in the second century A.D. The findings give evidence that extended periods of aridity have occurred at intervals throughout our past.

Castles in the Desert: Satellites Reveal Lost Cities of Libya
Satellite imagery has uncovered new evidence of a lost civilisation of the Sahara in Libya's south-western desert wastes that will help re-write the history of the country. The fall of Gaddafi has opened the way for archaeologists to explore the country's pre-Islamic heritage, so long ignored under his regime.
