Insulin under the influence of light

The disruption of internal clocks seems to play a significant role in the explosion of metabolic diseases observed in recent decades, particularly diabetes. Scientists have improved understanding of the importance of day-night ...

Researchers uncover mechanism blocking retina regeneration

A discovery opens the possibility of one day restoring loss of vision by activating the retina's ability to regenerate. Researchers at Baylor College of Medicine, the Cardiovascular Research Institute and the Texas Heart ...

Researcher seeks early detection to forestall glaucoma's ravages

Glaucoma is the leading cause of blindness in the U.S. and worldwide. More than 3 million Americans suffer from the eye disease. If caught and treated early, its progression can be significantly slowed, but the disease often ...

Neuroscience

Eyes have a natural version of night vision

To see under starlight and moonlight, the retina of the eye changes both the software and hardware of its light-sensing cells to create a kind of night vision. Retinal circuits that were thought to be unchanging and programmed ...

Neuroscience

Scientists visualize the connections between eye and brain

Most of the human brain's estimated 86 billion nerve cells, or neurons, can ultimately engage in a two-way dialogue with any other neuron. To shed more light on how neurons in this labyrinthine network integrate information—that ...

Medical research

Immune cells in the retina can spontaneously regenerate

Immune cells called microglia can completely repopulate themselves in the retina after being nearly eliminated, according to a new study in mice from scientists at the National Eye Institute (NEI). The cells also re-establish ...

Neuroscience

Unifying the theories of neural information encoding

Digital video cameras have the capability to record in incredible detail, but saving all that data would take up a huge amount of space. Researchers seek new methods to compress video—that is, remove information—in such ...
