Next-generation brain implants with more than a thousand electrodes can survive for more than six years

Get it straight - they're growing glass to implant into the brain.
Researchers have demonstrated the ability to implant an ultrathin, flexible neural interface with thousands of electrodes into the brain with a projected lifetime of more than six years.25 micrometers thick with 360 electrodes.Thermally grown layer of silicon dioxide less than a micrometer thick can ward off the hostile environment within the brain, degrading at a rate of only 0.46 nanometers per dayBecause this form of glass is biocompatible, any trace amount that dissolves into the body should not create any problems of its own.
Next-gen organoids grow and function like real tissues

Read the whole article and watch the video. Jeez.
Intestinal organoids. They're bio-engineered miniature intestines using a an artificial gut-shaped microchannel. Mini-guts.
They make the substrate out of proteins already found in the gut, cross-linking them into a hydrogel and forming it from a laser printer-cutter. The substrate, or scaffold, is then seeded with intestinal stem cells, that know how to do nothing else but make an intestine. And they do.

A lab that reads—and writes—our dreams
Apr 2020, phys.org
Dormio is a glovelike device that allows researchers to communicate with sleeping subjects as they slip into hypnogogia - a fleeting semi-conscious state between wakefulness and sleep, by tracking heart rate, muscle tone and skin conductance, as well as playing a word or other audio sound as subjects drift into the transitional sleep stage.
