New Life Found That Lives Off Electricity
...Yet early surveys suggest a potential microbial bounty. A recent sampling of microbes collected from the seafloor near Catalina Island, off the coast of Southern California, uncovered a surprising variety...
In the Deep, Clues to How Life Makes Light
...explained in several recently released studies, researchers have made significant progress in understanding the origins of bioluminescence — both evolutionary and chemical. The new understanding may one day allow bioluminescence...
Dividing Droplets Could Explain Life’s Origin
...of life’s humble beginnings, proposed that the mystery protocells might have been liquid droplets — naturally forming, membrane-free containers that concentrate chemicals and thereby foster reactions. In recent years, droplets...
Researchers Tap a Sleep Switch in the Brain
...recent paper in Nature, the researchers revealed two genes that seem to be involved in sleep’s biological machinery. The first was found in mice that need much more sleep than...
How Circadian Clocks Differ From Sleep
...more subtle than that. The circadian clock, as biologists have learned in recent decades, is in fact an incredibly precise molecular machine that exists in nearly every cell in the...
19 Women Leading Math and Physics
...are so few women in senior positions, aspiring researchers lack female mentors, perpetuating a sense of not belonging. In a recent interview, the French mathematician Sylvia Serfaty said that in...
Getting Into Shapes: From Hyperbolic Geometry to Cube Complexes and Back
...Ian Agol on a recent trip to Daejeon, South Korea. In 2008, in what Calegari calls “an astonishing breakthrough,”Agol showed that hyperbolic three-manifolds that satisfy a certain technical condition are...
Treading Softly in a Connected World
...model recently studied by D’Souza and her colleagues, sparse links between separate networks actually help suppress large-scale cascades, demonstrating that network models are not one-size-fits-all. To assess the behavior of...
As Machines Get Smarter, Evidence They Learn Like Us
...a car.” Neural networks have recently hit their stride thanks to Hinton’s layer-by-layer training regimen, the use of high-speed computer chips called graphical processing units, and an explosive rise in...
