  • The molecular switches regulating human cell growth do a great job of replacing cells that die during the course of a lifetime. But when they misfire, life-threatening cancers can occur. Research led by scientists at The University of Texas Health Science Center at Houston (UTHealth) has revealed a new electrical mechanism that can control these switches.

  • A new systematic review, published online in the peer-reviewed journal European Neuropsychopharmacology shows that modafinil does indeed confer significant cognitive benefits in in certain groups. This raises ethical questions over e.g. it's use in exams.

  • Insulin delivered high up in the nasal cavity goes to affected areas of brain and helps improve memory, claims a new study that may lead to new treatments for Alzheimer's and similar forms of dementia. "Before this study, there was very little evidence of how insulin gets into the brain and where it goes," said William Banks, University of Washington (UW) professor of internal medicine and geriatrics.

  • Research indicates that the use of condoms may cause some men to experience erection difficulties. However, in a study of 479 heterosexual men who used condoms and were 18 to 24 years old, those who reported condom-associated erection problems were also more likely to experience more generalized erection difficulties.

  • United States-based Myriad Genetics, the world's largest molecular diagnostic company, announced a strategic partnership with Positive Bioscience to offer the first of its kind molecular genomic testing in India. Genomic testing is still at an early stage in India and this partnership could revolutionise genomics testing in this country.

  • Woman who drink a glass of wine a day are at increased risk for developing breast cancer, says a new research. A daily glass of wine increased the chances of breast cancer for women significantly, whether or not they smoked, since smoking is not linked to breast cancer. The research was published online by the British Medical Journal.

  • A single dose of an experimental Ebola virus (EBOV) vaccine, currently undergoing testing in humans, completely protects monkeys against the current outbreak strain, when given at least seven days before exposure, scientists have found. The vaccine partially protects the cynomolgus macaques against the EBOV-Makona strain if given three days prior, researchers said.

  • With over 75 per cent of people in India being unaware about the existence of Hepatitis, the leading gastroenterologists of the country have decided to start an online data registry detailing the rising number of hepatitis patients. "The need of setting up a registry was felt as over 75 per cent of the people in India do not even know that a disease like hepatitis exists," said a senior doctor at AIIMS. "The aim is to keep a record of the number of people suffering from hepatitis and other liver diseases caused by it in the country," the doctor said.
