Scientists have tried to develop synthetic red blood cells that mimic the favorable properties of natural ones, such as flexibility, oxygen transport and long circulation times. But so far, most artificial red blood cells have had one or a few, but not all, key features of the natural versions. Now, researchers reporting in ACS Nano have made synthetic red blood cells that have all of the cells’ natural abilities, plus a few new ones.

Red blood cells (RBCs) take up oxygen from the lungs and deliver it to the body’s tissues...

A Mount Sinai research team has identified one of the mechanisms that establish the skin as a protective barrier, a breakthrough that is critical to understanding and treating common skin conditions including eczema and psoriasis, according to a study published Thursday, May 28, in the scientific journal Genes & Development.

One of the most important roles of the skin is to act as a barrier that prevents water loss and protects the skin from pathogens. Failure of this protective function contributes to dermatological diseases. The research team led by Sarah E...

A new type of test that uses complex sugars to detect prostate cancer earlier and with greater accuracy is being developed by researchers at the University of Birmingham. The test works by identifying sugars, known as glycans, in blood. These sugars are attached to protein molecules called PSA and are known to undergo distinct but subtle changes when cancer is present in the body.

Particular types of glycans are associated with different cancers – but until now, there has been no technology available to detect the glycans in an accurate, timely and sufficiently specific way.

Research led by a team in the University of Birmingham’s School of Chemical Engineering, has now developed a technique that can identify glycans associated with cancer with unprecedented accuracy...

Fitness tracker bracelets and watches provide useful information, such as step count and heart rate, but they usually can’t provide more detailed data about the wearer’s health. Now, researchers reporting in ACS Applied Materials & Interfaces have developed smart electronic glasses (e-glasses) that not only monitor a person’s brain waves and body movements, but also can function as sunglasses and allow users to control a video game with eye motions.

Devices that measure electrical signals from the brain (electroencephalogram; EEG) or eyes (e...
