The Hercules ultrafaint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to difficulties in ...

Purple sulfur bacteria (PSB) are important photoautotrophs inhabiting chemoclines in euxinic and meromictic lakes. These organisms are the only producers of the carotenoid, okenone, a compound that ...

10.1111/j.1365-2966.2012.20586.x The presence of substructure in galaxy groups and clusters is believed to be a sign of recent galaxy accretion and can be used to probe not only the assembly history ...

Carnegie biologist Kamena Kostova has been selected for the Director’s Early Independence Award from the National Institutes of Health, which is designed to provide “exceptional junior scientists” ...

Marine oxygen-deficient zones represent a natural source of nitrous oxide (N2O), a potent greenhouse gas and ozone-depleting agent. To investigate controls on N2O production, the responses of ammonia ...

Washington, DC— Pairing cutting-edge chemistry with artificial intelligence, a multidisciplinary team of scientists found fresh chemical evidence of Earth’s earliest life—concealed in 3.3-billion-year ...

In 1983, at the age of 81, Barbara McClintock received the news that would cement her place in scientific history. She had won a solo Nobel Prize in Physiology or Medicine for her discovery of ...
