43+ min ago   (148+ words) From flexible electrodes to biodegradable architectures, researchers are redesigning battery materials so that electrochemical reactions can do far more than supply power. Electrical stimulation can support wound healing, nerve regeneration, and bone repair. It can guide cell migration, promote Schwann-cell…...

16+ hour, 5+ min ago   (278+ words) Non-physicists might hear of 'the Hall effect' and think it relates to the way time elongates when trying to get young children out of the front door, or the phenomenon where you always forget your keys or phone as you…...

5+ min ago   (71+ words) Every growing season, farmers around the world spread millions of tonnes of urea onto their fields, and a startling share of it never reaches a crop. Urea is the most widely consumed nitrogen fertilizer on Earth, prized for its 46 percent…...

5+ min ago   (709+ words) Chemists have long regarded the allene and the alkyne as signatures of laboratory ingenuity rather than of living metabolism....

5+ min ago   (589+ words) Perovskite solar cells have long dazzled laboratory audiences with efficiencies that keep climbing year after year, yet the technology has stubbornly struggled to translate those record numbers into large-area modules that can be manufactured reliably at scale....

17+ min ago   (29+ words) Most rechargeable batteries depend on lithium, but researchers and manufacturers are also developing batteries that use sodium. Sodium is widely …...

21+ min ago   (467+ words) Chemists at Wenzhou Medical University have unveiled an electrochemical strategy that threads deuterium-labeled sulfur groups into enaminone scaffolds in a single cascade, and the resulting molecules show a striking ability to shield living cells from oxidative damage....

2+ week, 6+ day ago   (252+ words) Biomechanics is the scientific study of the mechanics of living structures, or of non-living structures such as silk or nacre that are produced by organisms. The recently extinct thylacine was Australia’s largest marsupial predator and famously likened to dog-family carnivorans…...

34+ min ago   (54+ words) X-ray imaging has long promised a tantalizing goal: the ability to peer inside intact, three-dimensional objects at nanometre resolution without slicing, staining, or otherwise destroying them. A newly reported advance in lensless holotomography moves that promise substantially closer to routine…...

5+ hour, 49+ min ago   (216+ words) For decades, many scientists have confidently dismissed the vast majority of the human DNA as useless evolutionary garbage. Yet a recently published scientific paper in Cell, one of the world’s most prestigious biology journals, declares a “paradigm shift” against the…...
