Spice it up or just veg out, either way you may be helping to defend against cancer
Two new studies suggest that broccoli and red chili pepper may slow or prevent the growth of cancerous tumor cells. The findings, being presented by the University of Pittsburgh at the American Association for Cancer Research's annual meeting, April 16 to 20, at the Anaheim Convention Center in Anaheim, Ca., looked at the effect of these dietary agents on ovarian and pancreatic cancers and found that both were effective inhibitors of the cancer process.

Scientists find a new beta cell maturation step triggered by weaning from milk to chow
Scientists have discovered a new developmental step in the process of beta cell maturation, triggered by the dietary transition from milk to chow. The findings indicate that transitioning from fat-rich milk to carbohydrate-rich food enhances beta cells' ability to secrete insulin in response to glucose, and allows glucose to stimulate beta cell replication. The researchers plan to study whether early weaning affects mice and humans' chances of developing diabetes. (2015-03-11)

Dietary changes help some children with ADHD
Together with child and adolescent psychiatrists, researchers from the University of Copenhagen have just completed an extensive report which reviews the studies which have been done so far on the significance of diet for children and young people with ADHD. The report shows that there are potential benefits in changing the diets of children with ADHD, but that key knowledge in the area is still lacking. (2012-04-24)

Nutrition intervention leads to dietary behavior changes in Latina breast cancer survivors
An intervention designed to provide Latina breast cancer survivors with the knowledge and skills needed to change and sustain dietary behaviors helps survivors adhere to recommended guidelines to eat a diet high in fruits and vegetables.

All-fiber optical wavelength converter
Wavelength conversion in all-fiber structure has extensive applications in new fiber-laser sources, signal processing, and multi-parameter sensors. Scientists from China developed a wavelength-converted optical fiber assisted by gallium selenide nanoflakes, which can convert the light wavelength efficiently via the second-order nonlinear optical effects. The device allows the easy operation with only sub-milliwatt continuous-wave laser over a broad wavelength range, and could be incorporated into existing optical fiber-based infrastructure to provide a wide range of applications.
