Scientists solve mystery of the eye

(PhysOrg.com) -- Scientists have a good overall understanding of human vision: when light enters our eyes, it is focused by the lens and strikes the retina in the back of the eye. The light causes some of the millions of ...

Regenerating bone with deer antler stem cells

Scientists from a collection of Chinese research institutions collaborated on a study of organ regeneration in mammals, finding deer antler blastema progenitor cells are a possible source of conserved regeneration cells in ...

A fungus that shrinks in size to better infect the brain

A fungus that is a common cause of fungal meningitis undergoes a remarkable transformation once it enters the body, allowing it to infect the brain, according to new research by scientists at University of Utah Health. Studies ...

How a fly's brain calculates its position in space

Navigation doesn't always go as planned—a lesson that flies learn the hard way, when a strong headwind shunts them backward in defiance of their forward-beating wings. Fish swimming upriver, crabs scuttling sideways, and ...

Biologists discover a trigger for cell extrusion

For all animals, eliminating some cells is a necessary part of embryonic development. Living cells are also naturally sloughed off in mature tissues; for example, the lining of the intestine turns over every few days.

New technique reveals genes underlying human evolution

One of the best ways to study human evolution is by comparing us with nonhuman species that, evolutionarily speaking, are closely related to us. That closeness can help scientists narrow down precisely what makes us human, ...
