A massive umbrella study, encompassing 277 clinical trials, into the effects of nutritional supplements and dietary interventions has concluded almost all vitamin and mineral supplements play no role in protecting from cardiovascular disease, or extending one's lifespan.
The new study gathered data from a large number of randomized clinical trials examining 16 vitamin supplements and their associations with general mortality and cardiovascular conditions such as heart attack or stroke. Almost all the supplements reviewed, including multivitamins, selenium, vitamin A, vitamin B6, and vitamin D, showed no association with either increased or decreased risk of death or heart disease.
Only three specific interventions displayed associations of any statistical significance. Unsurprisingly, the most relevant result was the finding that low-salt diets reduced heart disease and death by around 10 percent in healthy subjects. Both omega-3 and folic acid supplements showed small beneficial effects, but the researchers ranked these interventions as of a low impact.
A new two-step diagnostic process is claiming to confidently detect Alzheimer's disease nearly a decade before clinical symptoms appear. It's hoped that the method, which involves the measurement of both amyloid and tau proteins in blood and cerebrospinal fluid, will improve the results of clinical trials by helping better identify patients at the earliest stages of the disease.
The general hypothesis explaining the cause of Alzheimer's disease is that the aggregation of toxic amyloid and tau proteins in the brain results in neurodegenerative damage associated with cognitive decline. However a near-constant parade of clinical trial failures targeted at reducing the build-up of those toxic proteins have led to critical reconsiderations from many Alzheimer's researchers. While some scientists are investigating dramaticallydifferent hypotheses, others are suggesting the original protein hypothesis could still be correct, but simply needs to be targeted before any symptoms appear.

Currently, in order to reshape cartilage such as that within the nose, incisions and subsequent sutures are typically required. Not only is the procedure invasive, but it can also result in scarring. Now, however, scientists have demonstrated a new method of cartilage-reshaping that requires no cutting.
First of all, there already is a procedure in which an infrared laser is used to heat up cartilage, making it malleable enough to be molded into the desired shape. According to the University of California-Irvine's Dr. Brian Wong, however, the process is expensive, plus it's difficult the heat the cartilage sufficiently without killing it.
