Understanding why male mammals choose to mate with just 1 female
A new study in Science reports that scientists are getting closer to understanding a question they've long debated: why some male mammals -- who could mate with several females -- stick to just one. The new study, with authors from the University of Cambridge, is one of the field's most extensive to date.

Lizards' lessons for life
If you could somehow hit "replay" on the history of life, what would happen? Would the animals we see in this replay version of Earth look the same as the animals we see now?

Good news for gene therapy?
Gene therapy -- a process by which healthy "replacement" genes are infused into patients who have inherited faulty copies of the genes -- seems to work well in animal models of diseases. But, moving from animal research to the clinic has proved extremely challenging: The transplanted genes rarely express the right amount of proteins in human patients, and in some cases the treatment leads to negative side effects, like leukemia.

The origin of agriculture in the Fertile Crescent
Fossilized plant remains at an archaeological site in the foothills of the Zagros Mountains in Iran are telling researchers that the early inhabitants of the region began farming cereal grains, like barley and wheat, sometime between 12,000 and 9,800 years ago.

Class with Web-based and hands-on experiments wins Science prize
As a young student in Estonia, Margus Pedaste was very interested -- and quite brilliant -- in biology. When he was in the seventh grade, for instance, he conducted his first real research. And by the time he graduated from high school he had already won his country's annual biology "olympiad" three times.

Better oxygen storage deepens the dive
All mammals -- including you -- have oxygen-storing molecules, but deep-diving mammals like whales have adapted special versions of these molecules that let them hold their breaths for long periods, and a new study provides insight into just when this special capability evolved.

Birds of a colony eat together
Animals trying to determine where their feeding territory ends and the feeding territory of a competing animal nearby begins may be influenced just as much by signals they share with others in their colony as by spats and squabbles with members of competing colonies, reveals a new study in Science.

Human activity echoes through the Brazilian rainforest
The disappearance of large, fruit-eating birds from tropical rainforests in Brazil has caused the forests' palm trees to produce smaller, weaker seeds over the past century, researchers say. The finding makes it clear that human activity can trigger fast-paced evolutionary changes in natural ecosystems.

The secret lives of bubbles
A froth of soap suds, a handful of shaving cream or the mass of bubbles that sits on top of a freshly poured soda -- all of these things are foams or foam-like materials. They all have complex dynamics too, since the individual bubbles that make them up are constantly growing, popping and shape-shifting.

Robotic flies take to the skies
The common house-fly is one of nature's most agile fliers, capable of dodging flyswatters and carefully landing on flowers that are blowing in the wind. Now, researchers have designed a small, flying robot -- about the size of a house-fly -- that can execute the same tricky maneuvers.

Probing and proving gravity theory
Scientists have identified a neutron star, the densest kind of a star in the universe, which has helped them prove Einstein's theory of relativity in a place it's never been tested, a new study in Science reports.

Shining a light into the brain
Researchers have figured out a way to insert tiny electronic devices that can detect and control light into the brains of rodents without harming the animals. Until now, similar devices, like light sources and sensors, have been safely placed upon the brain. But, inserting such electronics directly into brain tissue has caused serious damage and irritation.

Termites behind desert 'fairy circles'
A new study uncovers the origin of fairy circles, circular patches of perennial grasses with a barren center that grow in the desert on the southwest coast of Africa. The research appears in the March 29, 2013, issue of the journal Science.

Taking robots off-roading
Researchers can learn a lot from a lizard scampering across the desert sand or an insect walking across some gravel, according to a new study. Chen Li and colleagues studied how objects move across these types of "flowable" surfaces and designed a six-legged robot that can do it easily.

Wings not lost, just hidden in some insects
The only limbs that can grow upon a modern insect's back are wings and wing-like structures, and they only appear on the second and third segments of an insect's thorax -- between their head and their abdomen. However, some insects in the fossil record seem to have wing-like "pads" on many of their non-winged body segments.

Prairie dogs take cooperation over competition
Why did the prairie dog cross the road? It might be because all of its close female relatives had already done so, according to a new study by John Hoogland. This researcher studied three different species of prairie dogs for more than 30 years and discovered that -- unlike many other animals -- prairie dogs tend to stay in the areas they are born until their close family members are gone.

Watching tiny particles in a Finland forest
All over the world, tiny airborne particles from volcanoes, dust, pollution and other sources float around in the atmosphere. New field studies in a boreal forest in Hyytiälä, Finland, and laboratory experiments reveal how these tiny particles, called atmospheric aerosols, are formed from gas molecules, a new study appearing in the journal Science reports.
