Scientists at the Francis Crick Institute and University College London have Rebuilt a human Thymus, an essential organ in the Immune system, using human stem cells and a bioengineered scaffold. Their work is an important step towards being able to build artificial thymi which could be used as transplants.

The thymus is an organ in the chest where T lymphocytes, which play a vital role in the immune system, mature. If the thymus does not work properly or does not form during fetal development in the womb, this can lead to diseases such as severe immunodeficiency, where the body cannot fight infectious diseases or cancerous cells, or autoimmunity, where the immune system mistakenly attacks the patient’s own healthy tissue.

Researchers at Drexel University’s College of Engineering have reported that fabric coated with a conductive, two-dimensional material called MXene, is highly effective at blocking electromagnetic waves and potentially harmful radiation. The discovery is a key development for efforts to weave technological capabilities into clothing and accessories.

Materials that block electromagnetic waves had a commercial moment a handful of years ago when fears that high-tech thieves could scan or copy credit cards, passports or hack into laptops and contactless car keys had people putting them in special wallets, bag...

In a new study, published online in the journal American Chemical Society (ACS) Applied Polymer Materials, scientists at Texas A&M University reported they have designed a hydrogel membrane that may be used to house optical glucose sensing materials, toward building a biosensor for monitoring sugar levels in diabetics.

By incorporating dangling, comb-type molecular chains within a type of hydrogel called poly(N-isopropylacrylamide) or poly NIPAAm for short, they showed that the membrane could prevent leakage of small-sized molecules, like the ones for glucose-sensing, while still allowing glucose to freely diffuse in and out.

When ready for clinical use, the researchers s...
