Retinal vein occlusion (RVO) is a severe disease that occurs when a vein in the light-sensitive layer at the back of the eye (i.e., the retina) becomes blocked, which results in a loss of vision. There are currently a few medical interventions that address RVO, including the periodic injection of medications that block the abnormal growth of blood vessels or of steroids, which reduce swelling and inflammation.

A promising procedure for the treatment of RVO is retinal vein cannulation (RVC)...

A blood test, combined with an ultrathin material derived from graphite, could significantly advance efforts to detect Alzheimer’s disease at its very earliest stage, even before symptoms appear.

Alzheimer’s disease is the most common form of dementia. For millions of Europeans—and the health services that care for them—it is a ticking time bomb, with still no cure. But EU researchers are developing a simple tool to enable much earlier detection, potentially decades before symptoms appear.

Early detection matters because treatment is most effective when started as soon as possible. This gives people a better chance to slow the progression of the disease and plan for the future...

New research from the WISE group (Wearable, Intelligent, Soft Electronics) at The University of Hong Kong (HKU-WISE) has addressed a long-standing bioelectronic challenge: the development of soft, 3D transistors.

This work introduces a new approach to semiconductor device design with transformative potential for bioelectronics. It is published in Science.

Led by Professor Shiming Zhang from the Department of Electrical and Electronic Engineering, Faculty of Engineering, the research team included senior researchers who joined HKU-WISE from the University of Cambridge and the University of Chicago, together with HKU Ph.D...

Children born to mothers who consume a high-fat, high-sugar diet during pregnancy and breastfeeding face a higher risk of developing fatty liver disease later in life.

New research from the University of Oklahoma suggests that risk may be reduced. A recent study has found that supplementing pregnant and lactating mice with a naturally occurring compound produced by healthy gut bacteria significantly lowered rates of fatty liver disease in their offspring as they aged.

The research is published in the journal eBioMedicine.

How gut bacteria compound may help
The compound, called indole, is naturally made by healthy gut bacteria when they break down tryptophan, an amino acid found in foods such as turkey and nuts...
