Soils offer new hope as carbon sink

...d pyrolysis. In The Bulletin magazine, Flannery recently ranked "fostering pyrolysis-based technologies" fourth among his five steps for saving the planet, because they convert crop waste into fuel and agrichar which can be used to enhance soil fertility and store carbon long-term.

Math that powers spam filters used to understand how brain learns to move our muscles

...nts to explain how the brain draws on both what it recently learned and what it’s known for some time to anticipate what it needs to develop new motor skills. The engineers, from Johns Hopkins, MIT and Northwestern, exploited the fact that all people show similar “probable” learning patterns and use them to ...

Discovery in orange cauliflower may lead to more nutritious crops
