CNN — An almost overlooked fossil discovered in a Brazilian museum collection has revealed the oldest ant specimen known to science, according to new research. The prehistoric ant lived among dinosaurs 113 million years ago — several millennia before previously found ants — and had an unusual way to kill its prey. Anderson Lepeco, a researcher at the Museum of Zoology of the University of São Paulo, said he came across the “extraordinary” specimen in [...]

This study, which was published in the journal Neurology, comes when clinicians and public health advocates are raising awareness of alcohol use disorder and issues related to excessive alcohol consumption. To help people think about their drinking [...]

CNN — You have probably seen leaf-cutter ants carrying bits of plants, maybe in a nature documentary, at a science museum or in the “Circle of Life” song at the beginning of the 1994 Disney animated film “The Lion King.” Those ants don't eat the leaves — instead they bring them back to their nests to feed a garden of fungi, which produce food for the ants. Researchers have now used DNA analysis to uncover just how long ants have been farming fungi, [...]

By Sandee LaMotte, CNN (CNN) — Tiny plastic shards and fibers were found in the nose tissue of human cadavers, according to a small new study. The threads and microplastic pieces were discovered in the olfactory bulb, the part of the nose responsible for detecting odors that sits at the base of the brain. “Once present in this structure, there can be translocation to other regions of the brain,” said lead study author Luís Fernando Amato-Lourenço, a [...]

CNN — The Amazon rainforest is on course to reach a crucial tipping point as soon as 2050, with devastating consequences for the region and the world's ability to tackle climate change, according to a study published Wednesday. The Amazon has proven resilient to natural changes in the climate for 65 million years, but deforestation and the human-caused climate crisis has brought new levels of stress and could cause a large-scale collapse of the forest system within the next three [...]

From deep in the Amazon rainforest, two dozen previously unknown pre-Columbian earthworks have been brought to light — and more than 10,000 such constructs may still be waiting to be discovered, according to new research. Across the Amazon basin, rainforests spread their leafy boughs over millions of kilometers. In the ground far below the treetops are ancient, long-hidden remnants of human habitation. They are preserved as ditches, paths and wells, sometimes forming geometric [...]
