1+ day, 4+ hour ago   (521+ words) Bacteria are famous for forming patterns, from the concentric rings of Proteus colonies to the branching networks that motile microbes paint across agar plates. Now researchers at Columbia University have turned one of biology’s most familiar workhorses, Escherichia coli, into…...

1+ day, 6+ hour ago   (661+ words) A single protein called BAX sits at the gateway between life and death for human cells. When tissues are injured, stressed, or deprived of oxygen, BAX springs into action, punching holes in the outer membrane of mitochondria and triggering the…...

1+ day, 7+ hour ago   (485+ words) A sprawling review of the meadow rue genus, Thalictrum, has catalogued a striking trove of biologically active plant chemicals across Africa and Asia, while simultaneously exposing how little of the evidence stands up to rigorous scientific scrutiny....

1+ day, 7+ hour ago   (704+ words) Cardiovascular medicine is quietly undergoing a structural rethink, and the change begins with the order of operations....

1+ day, 7+ hour ago   (534+ words) Mapping the wiring of the brain at nanometer resolution has long demanded a punishing trade-off: electron microscopy can reveal every synaptic cleft and organelle, but imaging even a cubic millimeter of neural tissue this way takes months or years of…...

1+ day, 7+ hour ago   (56+ words) A team of researchers in Japan has coaxed two bacteria working together to make one of the food industry’s most important amino acids directly from nitrogen gas, a feat that could loosen the grip of the energy-hungry Haber–Bosch process…...

1+ day, 9+ hour ago   (646+ words) Designing a polymerase chain reaction assay that reliably amplifies one stretch of DNA is a solved problem in most molecular biology laboratories....

1+ day, 9+ hour ago   (55+ words) Chemists in Pakistan have shown that the secret to extracting powerful antioxidant compounds from the leaves of the lemon-scented eucalyptus tree lies in matching the polarity of the solvent to the chemistry of the target molecules. In a study published…...

1+ day, 10+ hour ago   (75+ words) Rare cells punch far above their weight in biology. Populations that make up less than one percent of a tissue can drive tumor progression, immune evasion, drug resistance, and relapse, while others mark the first steps of lineage commitment or…...

1+ day, 10+ hour ago   (55+ words) The innate immune system is built on a paradox: the same molecular machinery that defends the body against infection can, when mishandled, turn that defense against the body itself. Few proteins embody this tension as vividly as NLRP6, a human pattern-recognition…...
