This enzyme enabled life to conquer a hostile earth

Computers are simulating the ancestral versions of the most common protein on Earth, giving scientists an unparalleled look at early life's development of harnessing energy from the Sun and production of oxygen.

Solar eclipse a chance to study life's resilience

On August 21, as North America experiences its first total eclipse of the Sun in 38 years, astrobiologists are taking advantage of this rare celestial event to conduct experiments on life's ability to survive hostile conditions.

Life evolves adaptions to microgravity

Life has found ways to overcome, and even thrive, in many extreme situations—from super saline pools to the high temperatures of hydrothermal vents. A new experiment has shown that the microgravity found in space is also ...

A big repeating molecule may be what defines life

As NASA inches closer to launching new missions to the solar system's outer moons in search of life, scientists are renewing their focus on developing a set of universal characteristics of life that can be measured.

Kepler has taught us that rocky planets are common

Rocky planets are probably a whole lot more common in our galaxy than astronomers previously believed—according to the latest release of Kepler Space Telescope data last week—a scenario that enhances the prospects for ...

Tides could be source of heat on icy moons

The icy moons in the outer solar system hold the potential for life, given that they may contain oceans of water. But life also needs a source of energy input to perform essential functions such as growth, reproduction and ...
