Time change: What neuroscience reveals about our internal clock

It's well-known that neural circuits help synchronize our biological clock with the day-night cycle. But just how exactly do those circuits develop, and can better understanding the process help, for example, in treating ...

Demystifying a visual illusion: Why we see color that's not there

A new discovery has unraveled why we sometimes see colors that aren't there. The phenomenon of "color afterimages" is when you see illusory—or false—colors after staring at real colors for a longer time. Through this, ...

Who is more likely to lose vision due to high brain pressure?

If untreated, a disorder of high brain pressure called idiopathic intracranial hypertension can lead to vision loss. But this disorder can develop without noticeable symptoms, making it hard to catch. A new study looks at ...

Combating intractable blindness with 3D bio-printed retina

Retinal vein occlusion (RVO) is one of the leading causes of vision loss worldwide, often triggered by chronic diseases such as hypertension and diabetes. Similar to a blocked water pipe causing backflow and pressure buildup, ...

Early trigger of diabetic eye disease identified

A team led by UCL scientists has identified a key protein that triggers diabetic retinopathy—a condition caused by high blood sugar damaging the retina's blood vessels and a leading cause of sight loss among working-age ...

Gene therapy discovery triggers hope for glaucoma patients

The protein tau is essential to the function of cells in the brain and central nervous system, but when over-produced under certain conditions, it forms tangles that clog the cells' internal structures. These tangles have ...
