Computing the origin of life

As a principal investigator in the NASA Ames Exobiology Branch, Andrew Pohorille is searching for the origin of life on Earth, yet you won't find him out in the field collecting samples or in a laboratory conducting experiments ...

How life could help atmospheric tides slow a planet's rotation

Resonating oscillations of a planet's atmosphere caused by gravitational tides and heating from its star could prevent a planet's rotation from steadily slowing over time, according to new research by Caleb Scharf, who is ...

Sharing life with the planets next door

How life could be shared between planets in close proximity to one another has received a greater insight thanks to new analytics based on previously known and new calculations. The findings are allowing researchers to understand ...

Was life on the early Earth purple?

Early life forms on Earth may have been able to generate metabolic energy from sunlight using a purple-pigmented molecule called retinal that possibly predates the evolution of chlorophyll and photosynthesis. If retinal has ...

Chlorate-rich soil may help us find liquid water on Mars

If liquid water exists on the surface of Mars, it is most likely in the form of a briny mixture with magnesium chlorate salts, according to new experiments based on discoveries previously made by NASA's Phoenix and Viking ...

New study identifies possible ancestors of RNA

Researchers from the Georgia Institute of Technology may have made headway in helping determine the origin of life by identifying three different molecules that self-assemble to form a molecular structure with features characteristic ...

How phosphorus came in from the cold

Phosphorus, which is vital to life but somewhat rare, condensed inside asteroids in the outer Solar System before moving back towards the sun, where some of it ended up on Earth, according to new research.

Earth's oxygen increased in gradual steps rather than big bursts

A carbon cycle anomaly discovered in carbonate rocks of the Neoproterozoic H├╝ttenberg Formation of north-eastern Namibia follows a pattern similar to that found right after the Great Oxygenation Event, hinting at new evidence ...
