World-leading eye experts have made a breakthrough that could potentially change the way cataracts are treated – with potential for drug therapy to replace surgery. Cataract is a clouding of the eye lens that develops over time and affects the quality of vision. It is caused by an accumulation of protein in the lens that

In nature, cilia flap independently, and mimicking these movements with artificial materials requires complex

Blocked blood vessels in the brains of stroke patients prevent oxygen-rich blood from getting to cells, causing severe damage. Plants and some microbes produce oxygen through photosynthesis. What if there was a way to make photosynthesis happen in the brains of patients? Now, researchers reporting in ACS’ Nano Letters have done just that in cells

Antiferromagnetic materials are attracting attention in spintronics, with the expectation of spin operations with higher

The results of the study were published in the first quartile journal

Scientists at the University of Colorado Boulder have tapped into a poltergeist-like property of electrons to design devices that can capture excess heat from their environment–and turn it into usable electricity. The researchers have described their new “optical rectennas” in a paper published today in the journal Nature Communications. These devices, which are too small
