New proteins, better batteries: Scientists are using AI to speed up discoveries
New artificial intelligence tools are being rapidly developed across the sciences. They may not be able to solve every problem, but in some cases, they're shortening the time to new breakthroughs.
Trio wins Nobel Prize in chemistry for work on quantum dots
Three scientists in the United States have won the Nobel Prize in chemistry for their work on quantum dots. Those are particles a few atoms in diameter that can release very bright colored light and are used in electronics and medical imaging.
Agostini, Krausz and L’Huillier win physics Nobel for looking at electrons in fractions of seconds
Three scientists won the Nobel Prize in physics for their work on how electrons zip around the atom during the tiniest fractions of seconds. The field could one day lead to better electronics or disease diagnoses. 
Nobel in medicine goes to 2 scientists whose work enabled creation of mRNA vaccines against COVID-19
Two scientists have won the Nobel Prize in medicine for discoveries that enabled the development of mRNA vaccines against COVID-19 and could be used in the future to create other shots.
250 million is the new 40: Mammals may already be halfway done on Earth, study finds
The future is always hard to predict, especially millions of years from now. But researchers found that a future supercontinent centered around the tropics may be tough for mammals to survive.
Three astronauts return to Earth after a year in space. NASA's Frank Rubio sets U.S. space record
A NASA astronaut and two Russian cosmonauts returned to Earth on Wednesday after being stuck in space for just over a year. American Frank Rubio set a record for the longest U.S. spaceflight — a result of the extended stay.
