Wine, medicine and movies are two great examples of how the naturalistic fallacy - the old ways are better - retain a vice-like grip on aspects of culture.  The naturalistic fallacy issues of wine tasting and medicine have been well-documented on Science 2.0 and, as anyone who got stuck watching "Crash" or "American Beauty" can tell you, awards and and critical acclaim in films also needs to be replaced with 21st century technology.

Beet juice is a fad in sports optimization because it is
rich in nitrates, but does it work? 

It has some value, though it does not enhance muscle blood flow or vascular dilation during exercise, as commonly claimed. It does "de-stiffen" blood vessels under resting conditions, potentially easing the workload of the heart. 

Crops genetically engineered to produce proteins from the bacterium Bacillus thuringiensis (Bt) to control insect pests have been planted on a cumulative total of more than a billion acres worldwide since 1996 and they have been very successful.

But pests evolve just like everything else and to avoid that, companies recommend a variety of strategies to avoid 'herd immunity'. Biotech companies have also introduced Bt crops called "pyramids" that produce two or more Bt toxins active against the same pest. They have been adopted in many countries since 2003, including the United States, India and Australia.

Autism Spectrum Disorder, a broad range of behavioral and cognitive issues that usually impair learning ability, has been studied for many years but there remain far more questions than answers. Some research into the brain functions of individuals with autism spectrum have found a lack of synchronization ('connectivity') between different parts of the brain that normally work in tandem, while other studies have found the opposite: over-synchronization. 

A new review of other studies concludes that viruses carried by commercial bees can jump to wild pollinator populations with potentially devastating effects. Pollinators in some regions have suffered declines and various hypotheses have been offered as to why.

A stem cell capable of regenerating both bone and cartilage has been identified in bone marrow of mice. The discovery by researchers at Columbia University Medical Center (CUMC) is reported today in the online issue of the journal Cell.

The cells, called osteochondroreticular (OCR) stem cells, were discovered by tracking a protein expressed by the cells. Using this marker, the researchers found that OCR cells self-renew and generate key bone and cartilage cells, including osteoblasts and chondrocytes. Researchers also showed that OCR stem cells, when transplanted to a fracture site, contribute to bone repair.
