Using new analyses, scientists found the last two of the five informational units of DNA and RNA that had yet to be discovered in meteorites

Scientists present more evidence for the oldest known fossils on Earth, which could bolster the search for alien life.

Researchers have for the first time been able to create an RNA molecule that replicates, diversifies and develops complexity.

Between 30 and 60 minutes of muscle strengthening activity every week is linked to a 10-20% lower risk of death from all causes.

Researchers in Australia say their latest project scanned billions of stars and 144 known exoplanets for signs of alien broadcasts.

All life consists of the same chemical building blocks. These include peptides, which perform various completely different body functions.

The missing link isn’t a not-yet-discovered fossil, after all. It’s a tiny, self-replicating globule called a coacervate droplet.

The hydrothermal crater lake of the Poás volcano in Costa Rica is one of the most hostile habitats on the planet.

Researchers discovered the structures of proteins that may be responsible for the origins of life in the primordial soup of ancient Earth.

Evidence demonstrates a close connection between the fraction of organic matter buried in sediments and changes in supernovae occurrence.

This has never been done before, to push macroscopic objects at speeds approaching the speed of light. Mass is such a huge barrier.

The new office will focus on incidents in, or near, "special use airspace" areas strictly controlled and blocked from general aviation use.

When Earth formed 4.5 billion years ago, any phosphorus that was present likely sank into the molten core due to the element's properties.

Among other goals, James Webb will search the atmospheres of alien planets for what scientists call "biosignatures" -- the presence of life.

A NASA sounding rocket will observe a nearby star to learn how starlight affects the atmospheres of exoplanets in the hunt for life.

While analyzing some of the world’s oldest coloured gemstones, researchers discovered carbon residue that was once ancient life.

Photosynthesis could occur in Venus' clouds with the middle and lower clouds receiving solar energy similar to the Earth's surface.

A rogue planet is an interstellar object of planetary mass without a host planetary system and could be fertile nurseries for life.

A droplet-based protocell could have served as a link between ‘chemistry’ and ‘biology’ during the origins of life.
