LOWELL, Mass. – Eggshells can enhance the growth of new, strong bones needed in medical procedures, a team of UMass Lowell researchers has discovered.
Artificial neural networks were created to imitate processes in our brains, and in many respects – such as performing the quick, complex calculations necessary to win strategic games such as chess and Go – they’ve already surpassed us. But if you’ve ever clicked through a CAPTCHA test online to prove you’re human, you know that our visual cortex still reigns supreme over its artificial imitators (for now, at least). So if schooling world chess champions has become a breeze, what’s so hard about, say, positively identifying a handwritten ‘9’? This explainer from the US YouTuber Grant Sanderson, who creates maths videos under the moniker 3Blue1Brown, works from a program designed to identify handwritten variations of each of the 10 Arabic numerals (0−9) to detail the basics of how artificial neural networks operate. It’s a handy crash-course – and one that will almost certainly make you appreciate the extraordinary amount of work your brain does to accomplish what might seem like simple tasks.

Evolution is one of nature’s most impressive forces, allowing organisms to adapt to changing environments to survive. By harnessing and guiding that process scientists have managed to manipulate micro-organisms into producing useful new drugs and materials, but it’s still a time-consuming process. Now, researchers at the University of North Carolina (UNC) have developed a new tool that speeds up the process in mammalian cells, creating new therapeutics in a matter of days.
In great news, five women have been appointed as the heads of the eight engineering departments at MIT.

An interesting article on how tsunamis caused by comets wiped out civilization in what is now the southeastern U.S. twice, in 539 and again in 1014. The bit about ammonia in the atmosphere also reminded me of the Norse prophecy about Thor wrestling with the Midgard Serpent, accompanied by poison in the air that kills many. I wonder how many strange things were witnessed by our ancestors for which they left us records that we are simply unable to understand.
Two massive comet or asteroid strikes in the past 1500 years altered Eastern North America’s history. The one in 539 AD devastated the South Atlantic Coast and permanently changed its geography. It left the South Atlantic Coastal Plain almost uninhabited. Hundreds of Uchee and Muskogean communities were wiped off the face of the earth. For obvious reasons, survivors headed north to the mountains.
