Exploring The Mysteries Of Asteroid Bennu
During the past year, there’s been an unusual set of samples at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab): material gathered from the 4.5-billion-year-old asteroid Bennu when […]
Dust From asteroid Bennu: Building Blocks Of Life And Possible Habitats Were Widespread In Our Solar System
It took two years for NASA’s OSIRIS-REx space probe to return from asteroid Bennu before dropping off a small capsule as it flew past Earth, which was then recovered in […]
Traces Of Ancient Brine Discovered On Asteroid Bennu Contain Minerals Crucial To Life
A new analysis of samples from the asteroid Bennu, NASA’s first asteroid sample captured in space and delivered to Earth, reveals that evaporated water left a briny broth where salts […]
Asteroid Bennu Sample Reveals A Mix Of Life’s Ingredients
Studies of rock and dust from asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security–Regolith Explorer) spacecraft have revealed molecules that, on our planet, […]
Study Sheds Light On The Origin Of Earth Life’s Genetic Code
Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of […]
Mapping the Edges of Mass Spectral Prediction: Evaluation of Machine Learning EIMS Prediction for Xeno Amino Acids
Mass spectrometry is one of the most effective analytical methods for unknown compound identification. By comparing observed m/z spectra with a database of experimentally determined spectra, this process identifies compound(s) […]
Order Of Amino Acid Recruitment Into The Genetic Code Resolved By The Last Universal Common Ancestor’s Protein Domains
The current “consensus” order in which amino acids were added to the genetic code is based on potentially biased criteria, such as the absence of sulfur-containing amino acids from the […]
Astrochemistry: The Mystery of Life’s Handedness Deepens
The mystery of why life uses molecules with specific orientations has deepened with a NASA-funded discovery that RNA — a key molecule thought to have potentially held the instructions for […]
Autocatalytic Assembly Of A Chimeric Aminoacyl-RNA Synthetase Ribozyme
Autocatalytic reactions driving the self-assembly of biological polymers are important for the origin of life, yet few experimental examples of such reactions exist.
