Squid tentacles are loaded with hundreds of suction cups, or suckers, and each sucker has a ring of razor-sharp "teeth" that help these mighty predators latch onto and take down prey. In a study published in the journal ACS Nano, researchers report that the proteins in these teeth could form the basis for a new generation of strong, but malleable, materials that could someday be used for reconstructive surgery, eco-friendly packaging and many other applications.

More than one quarter of children with two copies of a high-risk variant in a specific group of genes develop an early sign of celiac disease by age 5.

The findings are from The Environmental Determinants of Diabetes in Youth consortium, TEDDY, also found that participants in Sweden had higher rates of celiac disease than participants in the United States, Finland and Germany, even with the same genetic risks.

In 2002, President George W. Bush authorized funding for human embryonic stem cells (hESCs) using federal money for the first time - but he limited that federal funding to existing lines.

Researchers have identified the genes in wheat that control tolerance to a significant yield-limiting soil condition found around the globe; boron toxicity.

A new study has discovered that microRNAs (miRNAs), small RNA molecules that play important roles in regulation in many types of tissue, play a major role in the distribution and determination of fat cells and whole body metabolism. The study also finds that microRNAs influence the development of lipodystrophy (abnormal fat accumulation) which affects many people with HIV receiving anti-retroviral therapy. 

How do you shape your hopes, ambitions and expectations when growing up in an environment devastated by HIV/AIDS?

For her doctoral thesis, epidemiologist Ellen Blommaert looked for answers in Winam, a rural area of western Kenya where HIV/AIDS wreaked havoc among the population but where sexuality is very important.   She found that young people between 16 and 25 do modify their approach to sexual risks - but not in ways the western world understands. Sexuality plays an important role in their quest for a better future but because of the instability of social networks due to HIV and other factors, some of the youngsters increase their sexual networks, including, sometimes, sexual liaisons with multiple, concurrent partners.
