In a massive new analysis of findings from 277 clinical trials using 24 different interventions, Johns Hopkins Medicine researchers say they have found that almost all vitamin, mineral and other nutrient supplements or diets cannot be linked to longer life or protection from heart disease. Although they found that most of the supplements or diets were not associated with … [Read more...]
Sperm may offer the uterus a ‘secret handshake’
Why does it take 200 million sperm to fertilize a single egg? One reason is that sperm, when they arrive in the uterus, face a bombardment by the immune system. Perhaps, says molecular anthropologist Pascal Gagneux, many are needed so that some will survive. On the other hand, there may be a benefit to culling so many sperm. "I'm a lonely zoologist in a medical … [Read more...]
Study finds key metabolic changes in patients with chemotherapy-associated cardiotoxicity
More and more patients are being treated successfully for cancer. However, some cancer treatments that are very effective for breast cancer -- medications like anthracyclines and trastuzumab -- can cause heart dysfunction and lead to heart failure.

‘Seeing the light’ behind radiation therapy
Delivering just the right dose of radiation for cancer patients is a delicate balance in their treatment regime. However, in a new study from UBC Okanagan and Duke University, researchers have developed a system they say may improve the ability to maximize radiation doses to cancer tissues while minimizing exposure to healthy ones. "Radiation is a significant part of cancer … [Read more...]
Fat cell discovery could help combat obesity-related health issues
Researchers have discovered differences in fat cells that could potentially identify people predisposed to metabolic diseases such as diabetes and fatty liver disease. The world-first discovery also identified 'fast burning' fat cells that if unlocked might help people lose weight. About 70 per cent of Australians are overweight or obese, which has been linked to metabolic … [Read more...]

Cancers ‘change spots’ to avoid immunotherapy
Cancers can make themselves harder for new immunotherapies to see by 'changing their spots' -- and switching off a key molecule on the surface of cells that is otherwise recognised by treatment.
