Amazing whale photos. My mother would have loved them. (All our lives, we called her Whale. The reasons are lost in the mists of time.) 🧪

Turns out that the technology for better EV batteries is already here, get all the deets from our new explainer

Will your next EV have a solid-state battery — and improved performance?

Superionic materials have spawned hope for a new generation of power packs for electric cars, with a promise of greater range, faster charges and more safety. But scaling up won’t be easy.

Powerful piece by @richardastone.bsky.social about the rise in multidrug resistant bacteria in Ukraine's war-wounded and the threats the bugs also pose to non-soldiers and other countries. Very glad to see it in @knowablemag.bsky.social Thank you @pulitzercenter.org for funding Rich's travels. 🧪

A great piece by Elie Dolgin on the use of epigenetics clocks in conservation. Really interesting, a pleasure to edit and I do love the banner art! 🧪

How the cavefish lost its eyes — again and again 👀

Mexican tetras that got swept into pitch-black caverns had no use for the energetically costly organs. They lost their eyes in multiple ways — and gained some nifty traits too.

@timvernimmen.bsky.social's recent report is now available in Spanish👇

Los tetras mexicanos que fueron arrastrados a cavernas completamente oscuras no tenían ningún uso para esos órganos que consumían tanta energía. Perdieron sus ojos de múltiples maneras —pero también ganaron algunas características interesantes—.

An attosecond is a billionth of a billionth of a second.

Here's what that looks like written out:

0.000000000000000001 s.

And by the way: there are as many attoseconds in one second as there have been seconds ticking since the Big Bang.

Watching the world, one quintillionth of a second at a time
An attosecond is no time at all for a person. Not so for electrons, atoms and molecules. Laser-wielding scientists are revealing the action.
