Scientists Create “Nano-Suits” That Allow Bugs to Survive in A Vacuum

Scientists at the Hamamatsu University School of Medicine in Japan have come up with a special kind of spacesuit that can help keep insects alive in a vacuum. Unlike the gear astronauts wear, the nano-suit — as scientists are calling it — is more than 1,000 times thinner than a human hair and it’s made using electrons.

The moving story of an uncontacted Amazonian Indian on the run in the rainforest

  His name means “Hawk” in his language.

Like People, Bees Learn From Watching One Another

Bumblebees may not have the large, highly-developed brains that certain other animals possess – us highly intelligent primates, for example – but they can perform surprisingly sophisticated tasks, like using logic and picking up cues from their fellow bees.

Scientists Link Urban Noise To Decline In City Songbirds

It’s a fact: cities are loud. All that noise can have a deleterious effect on our lives, but humans aren’t the only ones negatively impacted by urban noise. Scientists have linked high levels of urban noise to a decline in songbird diversity.

Declining Forests In The Eastern United States As Seen From Space

Forests in the eastern United States have become less green over the past decade. That’s what scientists at NASA have concluded after analyzing a series of satellite images compiled between 2000 and 2010.

Rock Hyrax Urine Offers Clues About Climate Change

What can the rock hyrax – or, more specifically, the rock hyrax’s pee – tell us about climate change? More than you might think.

Help Astronomers Name Pluto’s Moons

P4 and P5? Surely you can come up with better names for Pluto’s newly-discovered moons. Astronomers at the SETI Institute are asking for your help.

Scientists Discover How Bacteria Changes Ions Into Gold

Bacteria with the ability to change ions into solid gold? This scenario may sound like a biochemist’s version of a fairy tale, but it’s real and scientists at McMaster University have just figured out how the process works.

Urban Weather: How Cities May Be Changing the Climate

Air pollution. Light pollution. Radical changes to local ecosystems. The profound environmental impact of cities is a popular topic among scientists these days. Now it appears that cities may actually be changing the weather — and the effects are being felt not just in urban areas, but in places thousands of miles away from major metropolises.

When people begin to worry about their mortality, they might fight the blues by buying a fancy sports car, having an affair, or even getting a toupee. But, what is a great ape to do?

Cool Math 101: Physicists Use Fluid Dynamics To Study Penguin Huddles

What do the members of the American Physical Society’s Division of Fluid Dynamics discuss during their annual meetings? Math, usually. Lots of math. But this week they’ll also be talking about something a little different: penguins.

After Sandy: Unusual Bird Sightings

Thanks to Hurricane Sandy, East Coast residents have been seeing a number of unusual guests at their bird feeders during the last two weeks.
