Designing fiber optic networks involves finding the most efficient way to connect phones and computers that are in different places – a costly and time-consuming process. Now researchers from North Carolina State University have developed a model that can find optimal connections 10,000 times more quickly, using less computing power to solve the problem.

Many people are careful to follow a low glycemic index (GI) diet. However, the glycemic index concept has some shortcomings, in the view of one young researcher, who has developed a complementary method, "glycemic profile," or GP. The findings were recently published in Nutrition Journal.

"White pasta is one example of a product which in some cases has received a bad reputation because of a high GI. However, white pasta produces just as good a blood glucose response as wholewheat pasta", says Liza Rosén, doctor in applied nutrition at Lund University in Sweden.

Tiny metallic particles produced by University of Adelaide chemistry researchers are bringing new hope for the production of cheap, efficient and clean hydrogen energy.

Led by Associate Professor Greg Metha, Head of Chemistry, the researchers are exploring how the metal nanoparticles act as highly efficient catalysts in using solar radiation to split water into hydrogen and oxygen.

LOMA LINDA, Calif. — Health disparities between black Americans and the rest of the nation have been well-documented in medical journals. But one study shows that blacks who identify as members of the Seventh-day Adventist Church actually report a better quality of life than the average American. Researchers point to certain lifestyle behaviors as a possible explanation for the difference. The research was conducted at Loma Linda University as part of the Adventist Religion and Health Study (ARHS), a study of nearly 11,000 Adventists, including more than 3,400 black Adventists.

They see more than the naked eye and could make traffic safer: miniaturized thermal imaging sensors. But they are difficult to manufacture on a commercial scale. Researchers have now developed a new system. On it, special micro-electromechanical systems can be produced -- with the correct etching technique.

BADAJOZ, SPAIN—The productivity and health of horticultural crops depends on the ability of the plant cover to intercept light energy. This ability is a function of the amount of leaf area, the architecture of the vegetation cover, and plants' ability to convert light energy. One estimate of a crop's ability to capture light energy is the leaf area index (LAI). Introduced in 1947, the concept of the LAI was defined as the ratio of leaf area to a given unit of land area. Today, understanding LAI is critical for successful crop management.

ROCHESTER, Minn. -- The 25.8 million Americans who have diabetes may soon be free of finger pricks and daily insulin dosing. Mayo Clinic endocrinologists Yogish Kudva, M.B.B.S., and Ananda Basu, M.B.B.S., M.D., are developing an artificial pancreas that will deliver insulin automatically and with an individualized precision never before possible.
