Researchers present the first fully integrated flexible electronics made of magnetic sensors and organic circuits which opens the path towards the development of electronic skin. Human skin is a fascinating and multifunctional organ with unique properties originating from its flexible and compliant nature. It allows for interfacing with external physical environment through numerous receptors interconnected with the nervous system. Scientists have been trying to transfer these features to artificial skin for a long time, aiming at robotic applications...

Scientists uncover link between the nervous system and stem cells that regenerate pigment. Scientists have found evidence to support long-standing anecdotes that stress causes hair graying. Researchers found that in mice, the type of nerve involved in the fight-or-flight response causes permanent damage to the pigment-regenerating stem cells in the hair follicle. The findings advance knowledge of how stress impacts the body, and are a first step toward blocking its negative effects.

The study, published in Nature, advances scientists’ knowledge of how stress can impact the body...

Researchers from the Faculty of Health and Medical Sciences have shown a possible link between a genetic variation and the widespread type of cardiac arrhythmia, atrial fibrillation.

The scientists conducted the study in zebrafish, which is a recognised scientific animal model within cardiac research.

Here, researchers from the University of Copenhagen in Denmark and the Max Planck Institute in Germany put special focus on the gene pitx2c. The result came as a surprise to them, says Assistant Professor Pia Lundegaard from the Department of Biomedical Sciences.

‘It seems that we may also have to think of atrial fibrillation as an atrial cardiomyopathy – that is, a challenged heart – rather than...

Biologists from The University of Manchester have explained for the first time why having a good night’s sleep really could prepare us for the rigours of the day ahead. The study in mice and published in Nature Cell Biology, shows how the body clock mechanism boosts our ability to maintain our bodies when we are most active.

And because we know the body clock is less precise as we age, the discovery, argues lead author Professor Karl Kadler, may one day help unlock some of the mysteries of aging.

The discovery throws fascinating light on the body’s extracellular matrix -which provides structural and biochemical support to cells in the form of connective tissue such as bone, skin, tendon and cartilage.

Over half our body weight is matrix, and half of this is collagen – and sci...
