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 sapiens, which arose in Africa about 300,000 years ago. The researchers sequenced the genomes of 39 Arabica varieties, including a specimen from the 18th century, to create the highest quality genome to date of this species, [...]

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 [...]
