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 ...

When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? Washington, DC— When a meteorite hurtles through the ...

New work from a Carnegie-led team including Liyin He, Lorenzo Rosa, and Joe Berry used satellites to measure both photosynthetic activity and aerosol pollution in Europe, demonstrating that plants ...

Pasadena, CA—New work from a research team including Carnegie’s Luke Bouma demonstrates that the Pleiades star cluster—also known as the Seven Sisters—is part of an enormous stellar complex spread ...
