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.
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.
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.
Residents from Oregon to Texas may be able to glimpse the annular eclipse, when the moon is deep in its orbit and passes in front of the sun, creating a black circle on the star.
Two scientists, one Nigerian and one American, created a cutting-edge surveillance network to catch the next emerging disease before it becomes a pandemic.
NASA's Osiris-REx mission sends a pristine sample of asteroid back to Earth Sunday morning. If it lands successfully, this cupful-or-so of space rock could shed light on the solar system's origins.
The horseshoe crab bleeding industry is in transition. One biomedical company agreed to more oversight, and a regulatory group is paving the way for drug companies to use animal-free alternatives.
