As soon as the calcium level exceeds a particular threshold over a longer period of time, an implant inserted under the skin triggers the production of melanin. This causes a mole to form. (Simulated montage) Credit: ETH Zurich

Researchers have developed an early warning system for the 4 most common types of cancer. Should a tumor develop, a visible mole will appear on the skin. Alongside cardiovascular disease, cancer has become the top cause of death in industrialised countries. Many of those affected are diagnosed only after the tumour has developed extensively. This often reduces the chance of recovery significantly: the cure rate for prostate cancer is 32% and only 11% for colon cancer...

Epstein-Barr virus may affect health in more ways than known. A far-reaching study conducted by scientists at Cincinnati Children’s reports that the Epstein-Barr virus (EBV) – best known for causing mononucleosis – also increases the risks for some people of developing seven other major diseases. Those diseases are: systemic lupus erythematosus (SLE), multiple sclerosis (MS), rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), inflammatory bowel disease (IBD), celiac disease, and type 1 diabetes. Combined, these seven diseases affect nearly 8 million people in the U.S.

Vertical graphene flakes form a protective surface that makes it impossible for bacteria to attach. Instead, bacteria are sliced apart by the sharp graphene flakes and killed. Human cells volume is typically 15,000 times larger. So, what constitutes a deadly knife attack for a bacterium, is therefore only a tiny scratch for a human cell. Coating implants with a layer of graphene flakes can therefore help protect the patient against infection, eliminate the need for antibiotic treatment, and reduce the risk of implant rejection. The osseointegration – the process by which the bone structure grows to attach the implant — is not disturbed. In fact, the graphene has been shown to benefit the bone cells.

Even moderate alcohol drinking linked to heart and circulatory diseases, study finds. Regularly drinking more than the recommended UK guidelines for alcohol could take years off your life, according to new research from the University of Cambridge. Part-funded by the British Heart Foundation, the study shows that drinking more alcohol is associated with a higher risk of stroke, fatal aneurysm, heart failure and death.

The authors say their findings challenge the widely held belief that moderate drinking is beneficial to cardiovascular health, and support the UK’s recently lowered guidelines...
