Paris (AFP) – Wildfires made more frequent and intense by climate change released significant quantities of CO2 into the air in 2023-2024, said a first-of-its-kind annual study published Wednesday. Fires in natural areas caused 8.6 billion tonnes of CO2 emissions worldwide between March 2023 and February 2024 -- 16 percent above average. Only a relatively calm fires season in the African savannah prevented the 2023-2024 season from breaking a fresh record for CO2 emissions at the [...]

Rio de Janeiro (AFP) – In Brazil, where about 16 wild animals become roadkill every second, a computer scientist has come up with a futuristic solution to this everyday problem: using AI to alert drivers to their presence. Direct strikes on the vast South American country's extensive road network are the top threat to numerous species, forced to live in ever-closer proximity with humans. According to the Brazilian Center for Road Ecology (CBEE), some 475 million vertebrate [...]

WASHINGTON : You might call it a cup of Joe, java, mud, brew, mocha, or your morning jolt. Coffee undoubtedly is a big part of global culture, and the kind made from the Arabica bean is the most appreciated by coffee drinkers. Researchers now have unlocked the genome of the Arabica species and traced its origins to a natural mating between two other coffee species an estimated 610,000 to one million years ago in the forests of Ethiopia. That makes this species older than our own species Homo [...]

There are few places on Earth as isolated as Trindade island, a volcanic outcrop a three- to four-day boat trip off the coast of Brazil. So geologist Fernanda Avelar Santos was startled to find an unsettling sign of human impact on the otherwise untouched landscape: rocks formed from the glut of plastic pollution floating in the ocean. Santos first found the plastic rocks in 2019, when she traveled to the island to research her doctoral thesis on a completely different [...]

WASHINGTON, Feb 8 (Reuters) - The small distant world called Quaoar, named after a god of creation in Native American mythology, is producing some surprises for astronomers as it orbits beyond Pluto in the frigid outer reaches of our solar system. Researchers said on Wednesday they have detected a ring encircling Quaoar akin to the one around the planet Saturn. But the one around Quaoar defies the current understanding of where such rings can form - located much further away from [...]

(Reuters) – The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that have yet to be certified by peer review. Coronavirus transforms pancreas cell function When the coronavirus infects cells, it not only impairs their activity but can also change their function, new findings suggest. For example, when insulin-producing beta cells in the pancreas become infected with the virus, they not only [...]
