Phys.org / Unexpected source of genetic diversity found in human sperm

Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome Sanger Institute, the ...

Medical Xpress / Motor neurons choreograph fruit fly feeding in millisecond-by-millisecond sequence

Eating may look effortless, but behind every bite, the brain runs a split-second relay of coordinated movement. In a recent study, researchers zoomed into the tiny world of fruit flies, or Drosophila, to uncover how their ...

Phys.org / Hyperdoped silicon photodiode advances short-wave infrared detection at room temperature

Detecting short-wave infrared (SWIR) light, a region of the electromagnetic spectrum just beyond the light visible to the human eye, could be advantageous for many real-world applications. For instance, it could enable more ...

Medical Xpress / Cancer is quantum: Studies show cancer cells may occupy limited, shared states like quantized energy levels

Andrea Califano began his career as a physicist. But that's not why he's now calling cancer a quantum disease. "We're really just following the data," says Califano, the Clyde '56 and Helen Wu Professor of Chemical Biology ...

Phys.org / Fleeting sugar pairs may help curb abnormal cell-growth signals

Acting as armor, a scaffold and a communication platform in one, our cells' plasma membrane lies at the heart of many crucial cellular processes. Traditionally, it has been thought to function through interactions among its ...
