In the water, it’s getting harder to breathe. Suffocating dead zones with little or no oxygen are pervading the world’s oceans, rivers, and streams. This phenomenon – which has exploded in recent decades – poses an extinction-level nightmare for marine populations already beset by a complex interaction of human-made menace. When it comes to these

Could anyone recommend a good algorithms MOOC or book? Even better if it is focused on bioinformatics/computational biology algorithms. I was going to start EdX’s UCSD Algorithm Designs and Techniques, but apparently the course is going to be archived by the end of this month so I was afraid it might not be up-to-date. Thanks.
HONG KONG — A Chinese scientist who claimed to have created the world’s first genetically edited babies “seriously violated” state regulations, according to the results of an initial government investigation reported on Monday by Chinese state media. The investigators’ findings indicate that the scientist, He Jiankui, and his collaborators are likely to face criminal charges.
Scientists may have just taken a step towards experimentally proving the existence of Hawking radiation.

If you look back far enough into Earth’s hazy, long-forgotten prehistory, things get weird.

Somewhere in the outer reaches of the Solar System, beyond the orbit of Neptune, something wonky is happening. A few objects are orbiting differently from everything else, and we don’t know why.

Black holes are great at sucking up matter. So great, in fact, that not even light can escape their grasp (hence the name).
