A new study led by researchers from the Institute of Atmospheric Physics of the Chinese Academy of Sciences (CAS) has uncovered the first observational evidence of lateral negative re-discharges occurring on negative leader ...
Phys.org / Scientists capture first detailed look inside droplet-like structures of compacted DNA
Inside human cells, biology has pulled off the ultimate packing job, figuring out how to fit six feet of DNA into a nucleus about one-tenth as wide as a human hair while making sure the all-important molecules can still function.
Medical Xpress / From field to lab: Study reveals how people with vision loss judge approaching vehicles
Patricia DeLucia has spent decades studying something many of us never think about: judgments about collisions that are crucial for safety. But the roots of her research stretch back to her childhood, long before she became ...
