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.
A new global assessment of the world's amphibians finds that more than 2 of every 5 known species is at risk of extinction. Habitat loss, disease and climate change are the main drivers.
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.
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.
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.
