In a new paper in the journal Science, researchers propose policies that would reward farmers for adopting “climate-smart” practices when growing biofuel crops and remove the hurdles that currently thwart such efforts. This could aid efforts to decarbonize agricultural as a whole, the scientists say. 

In a new study published in Current Biology, an international team of researchers discover the first evidence of an XX/XY sex determination system in chambered nautiluses and challenge the previously believed system of ZZ/Z0.

The team found fossils of Homo that confirm the earliest evidence for the human lineage at 2.8 million years ago as well as evidence of Homo at 2.6 million years ago, solidifying the antiquity of Homo. Unexpectedly, the team also found evidence that Homo overlapped at the site with a different type of hominin, Australopithecus, at 2.6 million years ago.  

A team led by researchers from the University of Washington used a fiber-optic cable to capture calving dynamics across the fjord of the Eqalorutsit Kangilliit Sermiat glacier in South Greenland. Data collected from the cable allowed them to document — without getting too close — one of the key processes that is accelerating the rate of glacial mass loss and in turn, threatening the stability of ice sheets, with consequences for global ocean currents and local ecosystems.
