As scientists explore ways to use genetic engineering to battle blindness, it’s obvious that gene therapy has gotten more sophisticated.
In traditional gene therapy, scientists “fix” a broken gene by supplying a healthy version to affected cells. Researchers have used this...

Vampire squid live slow. Even their gonads, it turns out, take vacations.
Any information about their reproduction is prized, because no one has seen the deep-sea dwellers even swim close enough to each other to flirt. Studies of fished-up specimens offer clues. But they can’t solve puzzles such as how sperm gets into female storage pouches, one...
Blair River was described as “a big guy with a big heart.” The 575-pound former high school wrestler from Mesa, Ariz., became such a fixture at the Heart Attack Grill that he was recruited to be the restaurant’s official spokesperson. His satirical ads made him a minor celebrity in central Arizona. He died in 2011 at age 29 — not because of his heart but from complications of influenza....

A man who had been blind for 50 years allowed scientists to insert a tiny electrical probe into his eye.
The man’s eyesight had been destroyed and the photoreceptors, or light-gathering cells, at the back of his eye no longer worked. Those cells, known as rods and cones, are the basis of human vision. Without them, the world becomes gray and formless, though not completely black. The...

Dream phase necessary — Dreaming sleep, which seems to be a necessity for man, may also be crucial for cats.… Scientists do not know exactly what function [REM sleep] periods serve in animals. For this reason, they call the phase paradoxical sleep.… [...
A new experiment captures a single parcel of light morphing between wave and particle.
Published in the April Physical Review A, the experiment dissects a light pulse associated with a single photon to expose wavelike and particle-like components. The results add to recent evidence suggesting that just as Schrödinger’s...
