This important study uses advanced computational methods to elucidate how environmental dielectric properties influence the interaction strengths of tyrosine and phenylalanine in biomolecular ...

So, if astrobiologists ever do find alien life with a weird chemistry that uses some liquid other than water, it's not likely to be methane, ammonia, or molten rock — but somewhere out there, alien ...

We’ve all had those afternoons where we feel tired or down and are crying out for something that will help lift our mood. While you can’t eat or drink your way into a good mood, there are certain ...

This image, taken by NASA's Osiris-Rex probe in December 2018, shows the asteroid Bennu. Scientists have identified 14 of the 20 amino acids used by terrestrial life, as well as the five nucleic acid ...

"L-serine, this particular amino acid that we used, [...] we can build it in our bodies ... where life evolved far away from anywhere it could feed itself via photosynthesis. NASA investigators too ...

L-tyrosine is an amino acid that's often used in supplements to improve cognitive function affected by stress. Supplements containing L-tyrosine supplements may also help treat phenylketonuria (PKU).

Of the 20 essential amino acids, nine are actually essential. Of those nine, three are branch-chain amino acids (BCAAs). Leucine falls into both groups. All BCAAS are vital for building and ...

“One of the goals [of astrobiology] is to go to [other worlds] and look for microorganisms, but in the meantime there’s so much we can do on Earth that will give us massive insights,” Nadeau says. And ...

led by Dan Glavin and Jason Dworkin of NASA’s Goddard Space Flight Center, focused on the detection of 14 of the 20 amino acids used by life to build proteins, deepening the mystery of why life only ...

The animation, provided by the NASA-funded Asteroid Terrestrial Impact Last Alert System, shows the path of a 130- to 300-foot-wide asteroid – named 2024 YR4 – having a more than 1% chance of ...

Scientists from NASA and other institutions who have been analyzing the Bennu asteroid sample that returned to Earth last September found molecules, including amino acids, which are essential ...
