New detection system to save millions of lives (Web Desk) - A more efficient, low-cost system to help detect microbes in water quickly and easily could help save millions of lives yearly in developing countries. A new device that detects water contaminants quickly, more efficiently, and cost-effectively can save millions of lives each year in developing countries. Recently, scientists from the Phutung Research Institute in Nepal, the University of São Paulo in Brazil, and 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, April 16 (Reuters) - 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 [...]

(Web Desk) - The world's trees may also be one of its most threatened organisms, according to a new study published Thursday in the journal Science. It finds that many more tropical tree species are in danger of going extinct far sooner than previously thought. The results add to the evidence for a growing, global biodiversity crisis as the climate warms and human activity pushes more and more plants and animals to the brink. "Reversing this crisis is a pressing [...]

(Web Desk) - In a recent breakthrough, researchers from Brazil have discovered novel peptides in the venom of two snake species: the lancehead pit viper Cotiara (Bothrops cotiara) and the South American bushmaster (Lachesis muta). These findings, funded by the São Paulo Research Foundation (FAPESP), pave the way for potential development of new blood pressure medications, underscoring the untapped potential of venom in medical applications. The study on the lancehead pit viper [...]

TRINDADE ISLAND, Brazil (Reuters) - The geology of Brazil's volcanic Trindade Island has fascinated scientists for years, but the discovery of rocks made from plastic debris in this remote turtle refuge is sparking alarm. Melted plastic has become intertwined with rocks on the island, located 1,140 km (708 miles) from the southeastern state of Espirito Santo, which researchers say is evidence of humans' growing influence over the earth's geological cycles. "This is new [...]

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 produce much less [...]

WASHINGTON (AP) — 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 [...]
