Supersulfides, many of which are produced by cysteinyl-tRNA synthetase (CARS), are essential compounds across many different lifeforms. However, the precise physiological roles of CARS-produced supersulfide are unclear. Now, using a strategically engineered yeast mutant with a deficient CARS gene, researchers from Japan have shown that supersulfides control cell longevity by mediating mitochondrial energy metabolism and regulating protein quality.

'Soft robots,' medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism -- thanks to a metal-free magnetic gel developed by researchers. Carbon-based, magnetic molecules are chemically bonded to the molecular network of a gel, creating a flexible, long-lived magnet for soft robotics.

Researchers have simplified the operation of an important class of chemical transformation: synthesis of beta-lactams, the intricate scaffold of many antibiotics. Their experimental protocol minimizes the toxicity that is a common feature of similar Fischer-carbene synthetic methodologies, and was used to synthesize the scaffold of the thienamycin antibiotic in high yield. This work is an important advancement in sustainable chemistry that should benefit drug development and other chemical syntheses.

A feeding method of the extinct jawless heterostracans, among the oldest of vertebrates, has been examined and dismissed by scientists, using fresh techniques.

RNA is thought to have sparked the origin of life by self-copying. Researchers have now revealed the atomic structure of an 'RNA copy machine' through cryo-EM. This breakthrough sheds light on a primordial RNA world and fuels advancements in RNA nanotechnology and medicine.

Neuroscientists have investigated whether playing violent video games leads to a reduction in human empathy. To do this, they had adult test subjects play a violent video game repeatedly over the course of an experiment lasting several weeks. Before and after, their empathic responses to the pain of another person were measured. It was found that the violent video game had no discernible effect on empathy and underlying brain activity.

A new experiment could in principle test the quantumness of an object regardless of its mass or energy.
