The discovery is just the latest to come from the asteroid sample, which dates back to the dawn of the solar system.

Penn State researchers think a key ingredient for life may have formed in deep freeze, not in a warm asteroid puddle. A space sample with a new twistScientists at Penn State; led by geoscientist ...

Amino acids from asteroid Bennu suggest that some of life’s building blocks formed in icy conditions in the early solar system.

Tiny grains of dust from asteroid Bennu are reshaping how scientists think life’s ingredients formed in space.

Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an asteroid called Bennu, delivered to Earth in 2023 by NASA's OSIRIS-REx ...

Leucine is the amino acid that signals your muscles to start repairing and growing. Here’s why it matters.

The traditional explanation of the initial genetic code in life seems less established when ancient proteins seem to be recalling some other arrangement of amino-acids. A recent examination of protein ...

Scientists have identified the molecular interactions that give spider silk its exceptional strength and flexibility, opening the door to new bio-inspired materials for aircraft, protective clothing ...

The first thing they noticed was that the infected mice were not eating as much—a sign of likely metabolic changes.

Many biological processes exhibit daytime differences governed by rhythmic exposure to sunlight, termed circadian rhythms. Researchers at Penn State recently found, in mice, that a protein critical to ...
