Chickenpox virus fatal in newly discovered immunodeficiency

A mutation in one of the sensors that the immune system uses to detect viruses can, in rare cases, turn infections with the chickenpox virus into a life-threatening matter. For two out of every 10,000 people, it can lead to inflammation of the brain, and for twenty out of 10,000, to severe pneumonia, which can [...]

Colorectal cancer death rates rising in people under 55

A new report finds that colorectal cancer mortality rates have increased in adults under 55 since the mid-2000s after falling for decades, strengthening evidence that previously reported increases in incidence in this age group are not solely the result of more screening. The rise was confined to white individuals according to the report, which appears [...]

Researchers discover potentially harmful nanoparticles produced through burning coal

Environmental scientists led by the Virginia Tech College of Science have discovered that the burning of coal produces incredibly small particles of a highly unusual form of titanium oxide. When inhaled, these nanoparticles can enter the lungs and potentially the bloodstream. The particulates – known as titanium suboxide nanoparticles – are unintentionally produced as coal [...]

Scientists develop improved, potentially safer Zika vaccine

The worldwide Zika threat first emerged in 2015, infecting millions as it swept across the Americas. It struck great fear in pregnant women, as babies born with severe brain birth defects quickly overburdened hospitals and public health care systems. In response, there has been a flurry of heroic scientific efforts to stop Zika. Whole governments, [...]

Biological bypass shows promise in coronary artery disease

A new gene therapy that targets the heart and requires only one treatment session has been found safe for patients with coronary artery disease, according to a successful trial carried out in Finland. Enhancing circulation in the oxygen-deficient heart muscle, the effects were visible even one year after the treatment. The randomised, blinded, placebo-controlled phase [...]
