Glacier changes at the top of the world

If greenhouse-gas emissions continue to rise, glaciers in the Everest region of the Himalayas could experience dramatic change in the decades to come. A team of researchers in Nepal, France and the Netherlands have found Everest glaciers could be very sensitive to future warming, and that sustained ice loss through the 21st century is likely. The research is published May 27 in The Cryosphere, an open-access journal of the European Geosciences Union. —> Read More

False breast cancer alarm has negative impact on health

The psychological strain of being told that you may have breast cancer may be severe, even if it turns out later to be a false alarm. This is the finding of new research from the University of Copenhagen, which has just been published in the scientific journal Annals of Family Medicine. Researchers call for improving screening accuracy, thus reducing the number of false-positive mammograms. —> Read More

The safe use of flavorings in e-cigarettes

Flavorings typically used are food grade, which means that are usually ingested rather than inhaled. ‘The data available is oral, but safe to eat is not the same as safe to inhale,’ says Sandra Costigan, Principle Toxicologist at Nicoventures, a nicotine company owned by BAT. ‘There are data gaps, but the meantime, what are the kinds of scientific rationale that will allow us to determine if we can use a flavor and at what level? —> Read More

Endoscopic removal of spinal tumor with the patient awake at Rhode Island Hospital

Albert Telfeian, M.D., a neurosurgeon at Rhode Island Hospital and Hasbro Children’s Hospital, performed the first reported case of extracting the tumor endoscopically while the 16 year-old patient was awake and under a local anesthetic. The minimally invasive procedure enabled accurate diagnosis, which evaded multiple physicians previously. The case report was published online in the journal, Clinical Neurology and Neurosurgery, and will appear in the July 2015 issue. —> Read More

Study links better ‘good cholesterol’ function with lower risk of later heart disease

HDL, the ‘good cholesterol’ helps remove fat from artery walls, reversing the process that leads to heart disease. Yet recent drug trials and genetic studies suggest that pushing HDL levels higher doesn’t reduce the risk of heart disease. Now, an epidemiological study shows that a person’s HDL function — the efficiency of HDL molecules at removing cholesterol — may be a better measure of coronary heart disease risk and target for heart-protecting drugs. —> Read More

Cocaine addiction, craving and relapse

One of the major challenges of cocaine addiction is the high rate of relapse after periods of withdrawal and abstinence. But new research reveals that changes in our DNA during drug withdrawal may offer promising ways of developing more effective treatments for addiction. Withdrawal from drug use results in reprogramming of the genes in the brain that lead to addictive personality, say researchers. —> Read More
