About 66 million years ago, a massive asteroid collided with what is now known as Yucatan, plunging Earth into darkness. The impact transformed the tropical rainforests, giving birth to flowers.
Today, tropical rainforests are a hotspot for biodiversity and play an important role in global climate systems. A new study was published today in
La science It sheds light on the origins of modern rainforests and can help scientists understand how tropical forests will respond to the rapidly changing climate of the future.
The study, conducted by researchers at the Smithsonian Tropical Research Institute (STRI), showed that an asteroid collision that ended the dinosaur reign 66 million years ago also caused the extinction of 45 % of plants in what is now Colombia, giving way. at risk of extinction. The reign of flowering plants in modern tropical forests. ....

Megalodon was 'much larger' than previously thought - scientists

Life-size models of the Megalodon were built at the Smithsonian Museum of Natural History in Washington DC, and another at the Western Australian Museum Boola Bardip in Perth. Scientists wanted to determine how big the megalodons actually were.
However, the two beasts vary in size - the Smithsonian s is 15 metres while the Perth one is 14 metres.
Both of these are slightly smaller than the 18 metre depiction which scientists had believed megalodons grew to, which prompted a scientific investigation.
John Long, strategic professor in palaeontology at Flinders University, and Mikael Siversson, head of deparment, Earth and planetary sciences at Western Australian University, began analysing teeth of megalodons and discovered the species was actually bigger than previously thought. ....

Shocking discovery: Electric eels hunt in packs in Amazon rivers -- Science & Technology -- Sott.net

When darkness comes,
electric eels emerge from South American river bottoms to attack their prey with up to 860 volts of electricity enough to kill a person. Now, scientists have revealed the snakelike fish don t always go it alone:
They hunt in packs, similar to wolves, orcas, and some species of tuna. The finding, a first among electric fishes, may open the way for new studies to investigate when social predation evolved among fishes.
I was shocked, says Douglas Bastos, a biologist at the National Institute of Amazonian Research who first saw a group attack in 2012. Usually the eels, which ....
