Summary Glioblastoma, the most aggressive adult brain cancer with a five-year survival below 5%, relies not only on glucose but also on the amino acid serine as an alternative carbon…
The diversity of microbial enzymes that turn a pollutant into an inert gas Summary Reductase enzymes convert the potent greenhouse gas nitrous oxide (N2O) into harmless dinitrogen (N2). A new…
Earth’s capacity to store carbon could max out surprisingly soon Summary Researchers estimate that Earth can safely store roughly 1,460 gigatonnes of carbon dioxide (GtCO₂) in stable sedimentary basins once…
Damaged bridges flex and twist to prevent collapse Summary Steel truss bridges — built from connected frames of members — can sometimes avoid catastrophic failure when a load-bearing element breaks…
Cocaine-activated ion channels engineered to break the loop of addiction in rats Summary Researchers have engineered ion channels that are selectively activated by cocaine and that can either stimulate or…
Ancient DNA connects large-scale migration with the spread of Slavs Summary This Nature study combines newly generated ancient DNA from 591 individuals with published datasets to create dense temporal and…
Amygdala–liver signalling orchestrates glycaemic responses to stress Key Points • The medial amygdala (MeA) is rapidly activated by physical, social and visual stressors and its activity precedes rises in blood…
PICALM Alzheimer’s risk allele causes aberrant lipid droplets in microglia Key Points • Genome-wide ASoC mapping in human iPSC‑derived microglia (iMGs), astrocytes and neurons prioritises functional non-coding LOAD risk variants;…
Commensal yeast promotes Salmonella Typhimurium virulence Summary This Nature paper shows that the common gut fungus Candida albicans can increase the virulence of Salmonella Typhimurium (STm) by producing l-arginine after…
Supervised learning in DNA neural networks Summary This paper demonstrates a DNA-based molecular system that performs supervised learning and subsequent classification entirely in vitro. The authors extend DNA strand-displacement ‘seesaw’…
