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, [...]

(Reuters) – Brazilian space research center INPE said on Wednesday that carbon emissions in the Amazon forest soared in 2019 and 2020 compared to the previous decade due to poor enforcement of environmental protection policies. The forest’s carbon emissions amounted to 0.44 billion metric tons in 2019 and 0.52 billion metric tons in 2020, compared to an annual average of 0.24 billion metric tons from 2010-2018, according to the INPE study published in Nature magazine. The [...]

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 [...]

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 it than current scientific [...]
