New nerve cells represent a quantum jump for regenerative therapy.

Unlike other reprogrammed stem cells, these can continue to multiply in a lab.

Remarkable! 🎸 🎶

Specialized Cells In Eye Linked To Mood Regions In Brain : Shots — Health News Research suggests the winter blues are triggered by specialized light-sensing cells in the retina that communicate directly with brain areas involved in mood.

Something ‘bumped’ into Uranus.

And it could reveal secrets about the origins of our universe.

And it’s billions of years old.

These days, movies and video games render increasingly realistic 3D images on 2-D screens, giving viewers the illusion of gazing into another world. For many physicists, though, keeping things flat is far more interesting.

One reason is that flat landscapes can unlock new movement patterns in the quantum world of atoms and electrons. For instance, shedding the third dimension enables an entirely new class of particles to emerge—particles that that don’t fit neatly into the two classes, bosons and fermions, provided by nature. These new particles, known as anyons, change in novel ways when they swap places, a feat that could one day power a special breed of quantum computer.

But anyons and the conditions that produce them have been exceedingly hard to spot in experiments. In a pair of papers published this week in Physical Review Letters, JQI Fellow Alexey Gorshkov and several collaborators proposed new ways of studying this unusual flat physics, suggesting that small numbers of constrained atoms could act as stand-ins for the finicky electrons first predicted to exhibit low-dimensional quirks.

Happy holidays! The winter break is here, and LEAF too will shift to a lower gear for a little while, but on the plus side, our readers get the Rejuvenation Roundup early! Before we leave you to unwrapping presents and having dinner with the family, let’s recap what has been going on in the field of rejuvenation during the last month of the year.
