Printed polymer allows researchers to explore chirality and spin interactions at room temperature

Phys.org 

A printable organic polymer that assembles into chiral structures when printed has enabled researchers to reliably measure the amount of charge produced in spin-to-charge conversion within a spintronic material at room temperature. The polymer's tunable qualities and versatility make it desirable not only for less expensive, environmentally friendly, printable electronic applications, but also for use in understanding chirality and spin interactions more generally.

Driving photochemistry with sub-molecular precision

Phys.org 

Absorption of light initiates many natural and artificial chemical processes, for example, photosynthesis in plants, human vision, or even 3D printing. Until now, it seemed impossible to control a light-driven chemical reaction at the atomic scale, where only a specific part of one molecule is addressed.

Scientists generate new targeted protein degradation system that tunes a cell's own proteins

Phys.org 

Researchers studying the role of proteins in health and disease use experimental tools that inactivate proteins, destroy them, or prevent them from being made in cells. In one approach, they mark targeted proteins with "destroy me" tags that work with small molecules known as molecular glues to prompt the cell's own protein-clearing machinery to gobble up the proteins. Yet, many tags used today are too large to tag the genes that encode a cell's native proteins, or they cause collateral damage, sparking... Читать дальше...

While Waiting challenges you to make your own fidgety fun as you puzzle through life's little pauses

Rock Paper Shotgun 

What do you reach for when you're waiting in line at the supermarket, or waiting in a shop doorway for the rain to stop, or even while you're waiting for a game to finish downloading? I don't mean to assume, but let's face it, it's probably your phone, where some idle doomscrolling likely awaits you, or some other, time-wasting distraction that will help fill the dead air between one task and the next. Well, While Waiting is a game that delves into precisely this fundamental human question: what... Читать дальше...
