Lithium-ion batteries (LiBs) are among the most widespread rechargeable battery technologies, due to their high energy densities and performances. Despite their versatility and advantageous characteristics, these batteries often require specific times to charge and speeding up these charging times has so far proved challenging.

The main reason for this is that during fast charging, lithium plating could form on the batteries’ graphite anode, which could pose safety risks. In fact, lithium plating reactions on graphite anodes, which can also occur at low temperatures, during overcharging or following battery malfunctions, can lead to the formation of non-cyclable lithium metal and salts, which could ignite causing fires or battery explosions.

Researchers at University of California, Berkeley and the Lawrence Berkeley National Laboratory recently carried out a study investigating potential ways to reduce these risks and enable the creation of safe fast-charging LiBs. Their paper, published in Nature Energy, outlines a series of simple techniques for quantifying irreversible Li plating on the graphite anodes inside LiBs.

The ‘presented images’ were shown to a group of humans. The ‘reconstructed images’ were the result of an fMRI output to Stable Diffusion.

In other words, #stablediffusion literally read people’s minds.

Making an embryo is much like making a Lego castle: In the same way that a castle needs turrets and gargoyles and a moat, you need two legs and two eyes and a heart.

Except unlike the Lego Camelot, you don’t come with a picture on the box of what you’re meant to look like, much less an instruction manual—and you’re not going to be the one to assemble the structure. Instead, you’ll sit back and wait for the Lego pieces to organize themselves. Our cells, our little Lego pieces, assembled themselves. What’s even more astonishing is that when they get it right, all those cells get it right in broadly the same ways: We all managed to come out with the characteristic shape and proportions appropriate to our species (we can all spot a regulation-issue chicken, frog, mouse, or human shape).
