Researchers, in this case, found evidence that suggests a host of tropical mammals regularly visit particular trees known to play a role in traditional medicine. The work was published in the journal BioTropica.

Publicado em 11 setembro 2019Two new electric eel species have been identified in the Amazon basin, including one fish with a record-breaking shock, scientists say. Researchers had previously identified only one species of electric eel in more than 250 years of studying the creatures that lurk in South American waters and stun their prey with electric discharges. However, the new genetic and ecological analysis, published Tuesday in the peer-reviewed Nature Communications, identifies a total of three unique [...]ver notícia -
From Victim’s Remains, Scientists Estimate Hiroshima Radiation Doses
Publicado em 30 abril 2018Before dropping the first nuclear bomb ever used in combat, American scientists studied Japan looking for a target that could maximize damage.

Then weapons engineers dialed in the bomb’s settings – they wouldn’t need much pressure to level the city’s thatched roof houses. Some 70,000 people died on August 6, 1945, as Little Boy struck Hiroshima, wiping out roughly 70 percent [...]ver notícia
