Low river discharge reduces the likelihood of young Atlantic salmon reaching the North Sea. Fewer salmon reach the Haringvliet sluices, and their passage takes longer, making them more likely to fall prey to predators. Using so-called predation tags, researchers were able to demo

A landmark study of nearly 4,000 babies found that acetaminophen and ibuprofen were equally safe during infancy. Neither medicine was linked to eczema or bronchiolitis, and no serious side effects were caused by the drugs. Researchers will continue following the children through

The dodo has been extinct for more than 300 years, wiped out within decades of humans arriving on its home island of Mauritius, but it lives on in the public imagination.

Scientists have uncovered a surprising way that “jumping genes” may move between species and speed up evolution. While these mobile genetic elements were thought to travel mainly inside viruses or plasmids, researchers found circular intron RNA from a tiny predatory bacterium ins

Back in 2000, EVs were pretty weird. O recorte ajuda a contextualizar a pauta dentro de Auto.

With many fan-favorite Autobots and Decepticons bumped off in the opening act, this was not the big-screen romp '80s kids were expecting.

In southeastern Madagascar, patches of forest that were once cut down to make way for farms are slowly regenerating naturally after being left to lie fallow. But recovering a native forest needs more than just gaining tree cover. The animals that once lived in these forests also

A study tracking more than 340,000 adults for over a decade found that heavy drinking increased the risk of death regardless of beverage type. At lower levels, however, the picture became more surprising: beer, cider, and spirits were linked to higher mortality, while wine was as

Chemists have developed a catalyst that breaks a long-standing rule governing which molecules receive electrons during chemical reactions. By releasing electrons directly into solution, the technique could unlock reactions—and potentially useful new molecules—that were previously
