Publicado em 15 de abril de 2024
That coffee you slurped this morning? It’s 600,000 years old.
Using genes from coffee plants around the world, researchers built a family tree for the world’s most popular type of coffee, known to scientists as Coffea arabica and to coffee lovers simply as “arabica.”
The researchers, hoping to learn more about the plants to better protect them from pests and climate change, found that the species emerged around 600,000 years ago through natural crossbreeding of two [...]

Jolting discovery: Powerful new electric eel found
Publicado em 11 setembro 2019WASHINGTON — Researchers report two newly discovered species of electric eels in South America, one of which can deliver a bigger jolt than any other known animal. The researchers collected 107 eels in four countries and found differences in their DNA, along with minor physical variations. One species had the ability to generate 860 volts of electricity, more than the 650 volts discharged by the only previously identified type of electric eel. While 250 species of fish in South America [...]ver notícia -
Electric eel sting delivers 860 volts of juice in massive jolt, study finds
Publicado em 11 setembro 2019An electric eel newly discovered in the Amazon can deliver a massive jolt of 860 volts of electricity much greater than the 650 volts previously measured and the strongest of any animal. "Eight hundred and sixty volts is an incredible output of electricity for an animal. Our electric plug points are 110 volts," study co-author Casey Dillman, curator of fishes, amphibians and reptiles at the Cornell University Museum of Vertebrates, said in a news release. It may not be a big [...]ver notícia
