A nanocellulose wound dressing that can reveal early signs of infection without interfering with the healing process has been developed by researchers at Linköping University, Sweden. Their study, published in Materials Today Bio, is one further step on the road to a new type of wound care.

The skin is the largest organ of the human body. A wound disrupts the normal function of the skin and can take a long time to heal, be very painful for the patient, and may—in a worst-case scenario—lead to death if not treated correctly. Also, hard-to-heal wounds pose a great burden on society, representing about half of all costs of out-patient care.

In traditional wo...

Researchers led by Northwestern University and the University of Texas at Austin (UT) have developed the first cardiac implant made from graphene, a two-dimensional super material with ultra-strong, lightweight and conductive properties.

Similar in appearance to a child’s temporary tattoo, the new graphene “tattoo” implant is thinner than a single strand of hair, yet still functions like a classical pacemaker. But unlike current pacemakers and implanted defibrillators, which require hard, rigid materials that are mechanically incompatible with the body, the new device softly merges with the heart to simultaneously sense and treat irregular heartbeats...

When a person reads a sentence, two distinct networks in the brain are activated, working together to integrate the meanings of the individual words to obtain more complex, higher-order meaning, according to a study at UTHealth Houston.

The study, led by Oscar Woolnough, Ph.D., postdoctoral research fellow in the Vivian L...

Neutron and light scattering, along with atomic force microscopy and quartz crystal microbalance, illuminate a mechanism explaining the ‘vicious circle’ of osteoarthritis.

The exact mechanism of cartilage breakdown in osteoarthritis is unknown, but damage from mechanical stress with insufficient self-repair is believed to be the main culprit...
