Everlasting youth, and the hunt for brand new metals

[ad_1]

A bit over 15 years in the past, scientists at Kyoto College in Japan made a outstanding discovery. After they added simply 4 proteins to a pores and skin cell and waited about two weeks, among the cells underwent an sudden and astounding transformation: they turned younger once more. They was stem cells virtually similar to the type present in a days-old embryo, simply starting life’s journey.

No less than in a petri dish, researchers utilizing the process can take withered pores and skin cells from a 101-year-old and rewind them in order that they act as in the event that they’d by no means aged in any respect.

Now, after greater than a decade of learning and tweaking so-called mobile reprogramming, various biotech firms and analysis labs say they’ve tantalizing hints that the method may very well be the gateway to an unprecedented new expertise for age reversal. Learn the complete story.

This piece is from our forthcoming mortality-themed challenge, launching tomorrow. If you wish to learn it when it comes out, you’ll be able to subscribe to MIT Know-how Assessment for as little as $80 a 12 months.

Machine studying might vastly velocity up the seek for new metals

The information: Machine studying might assist develop new kinds of metals with helpful properties, akin to resistance to excessive temperatures and rust, in keeping with new analysis. A staff of researchers from the Max Planck Institute managed to determine 17 promising new metals utilizing AI, which predicts which mixtures of metals will present promise much more exactly than present strategies of laboratory experimentation.

Why it issues: The invention might show helpful for a variety of sectors—for instance, metals that carry out properly at decrease temperatures might enhance spacecraft, whereas metals that resist corrosion may very well be used for boats and submarines. It might additionally pave the best way for higher use of machine studying in supplies science. Learn the complete story.
