Moveable displays made of paper
A new version of ‘zero-knowledge proofs’ allows cloud customers to detect program-tampering
Researchers discover how immune system kills healthy cells
Researchers link obesity and the body's production of fructose

Recently at the 2013 IFA international trade show for consumer electronics and home appliances in Berlin, major electronics manufacturers displayed new types of displays that are thin, and even curved, but expensive. IT experts in Saarbrücken have gone a step further. Their more cost-effective approach, called Flexpad, allows a simple, standard sheet of paper to be transformed into a moveable, flexible display. Already today, this could help patients better review the results of a computer tomography, for example.

A new version of ‘zero-knowledge proofs’ allows cloud customers to detect program-tampering

For small and midsize organizations, the outsourcing of demanding computational tasks to the cloud — huge banks of computers accessible over the Internet — can be much more cost-effective than buying their own hardware. But it also poses a security risk: A malicious hacker could rent space on a cloud server and use it to launch programs that hijack legitimate applications, interfering with their execution.

Researchers discover how immune system kills healthy cells

Medical scientists at the University of Alberta have made a key discovery about how the immune system kills healthy cells while attacking infections. This finding could one day lead to better solutions for cancer and anti-viral treatments.

Faculty of Medicine & Dentistry researcher Colin Anderson recently published his team’s findings in the peer-reviewed journal, Journal of Immunology. His team included colleagues from the United States and the Netherlands, and graduate students from the U of A.

Researchers link obesity and the body's production of fructose

Researchers at the University of Colorado School of Medicine reported today that the cause of obesity and insulin resistance may be tied to the fructose your body makes in addition to the fructose you eat.

In recent years the role of added sweeteners, such as high fructose corn syrup and table sugar (sucrose), has taken center stage as risk factors for obesity and insulin resistance. Numerous studies suggest that the risk from added sugars may be due to the fructose content.
