A diabetes epidemic that appears to have claimed the life of composer Johann Sebastian Bach may explain baffling disparities in the diseases rates among 21st-century ethnic groups, a UCLA geographer and evolutionary biologist says in the current issue of Nature.
Aside from speculating that many people may carry genes that predispose them to diabetes, researchers have been at loss to explain why, for instance, only 2 percent of Europeans contract the disease as opposed to 13 percent of African Americans, 17 percent of U.S. Latinos and up to 50 percent of Native Americans.
"Immediately following Europes last widespread famines centuries ago, a diabetes epidemic appears to have killed a large number of Europeans with these genes before they could be passed on to successive generations," said Jared Diamond, a UCLA professor of geography and environmental heath sciences. "Meanwhile, traditionally poor or rural non-European populations have not experienced a diabetes epidemic -- until lately. So these people still carry the genes in large measure, and as a result they become highly prone to diabetes when they move into urban or Westernized settings, where the diseases risk factors are more common."

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
