Coral bleaching, a deadly disease that strikes reefs when oceans heat up, has risen nearly five-fold since the 1980s, threatening the future of these vital ecosystems, researchers said Thursday.
Severe coral bleaching events used to happen once every 25 to 30 years. Now, they occur every six years on average, said the report in the journal Science.
"Before the 1980s,Read more
Chinese scientists have pulled off a major feat with one of the sub-atomic world's weirdest phenomena: photons that behave like twins and experience the same things simultaneously, even over great distances.
The space-based technique developed by the researchers and reported in the journal Science holds potential for revolutionizing telecommunications and perhaps someday developing a hack-proof internet.
The principle is calledRead more
Scientists who study patterns of natural shifts in the Earth's climate said Thursday they have uncovered a "worrisome" signal that major sea level rise could be on the way.
The findings in the journal Science show that ocean surface temperatures during the Earth's last warm period, some 125,000 years ago, were remarkably similar to today.
But what concerns scientists isRead more
An unexpected sugary snack can give bees a little buzz and appears to lift their mood, even making them optimistic, according to research Thursday that suggests pollinators have feelings, too.
Since emotions are subjective and difficult to measure — particularly in animals — researchers looked at how bees’ behavior changed after they were given a sip of sucrose solution.
TheyRead more
