A gene present in nearly one in eight people is the most commonly inherited cancer susceptibility gene identified so far, increasing cancer risk in carriers by 26 percent, according to a study published by researchers at Chicagos Northwestern Memorial Hospital in todays Journal of Clinical Oncology. More common than the BRCA gene mutations, Transforming Growth Factor Beta Receptor 1*6A (TGFBR1*6A) may increase risk of breast cancer by 48 percent, ovarian cancer by 53 percent, and colon cancer by 38 percent.
"This is an exciting finding because TGFBR1*6A is a common gene that may cause a large number of cancers. In the near future, it will be commonplace for people to know what genes make them more susceptible to cancer, and well have many more options for preventing those cancers," says Boris Pasche, M.D., Ph.D., F.A.C.P., director of Northwesterns Cancer Genetics Program, assistant professor of medicine at the Feinberg School of Medicine and a researcher at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University.
Researchers analyzed seven published studies and pooled those results to conclude that the TGFRB1*6A gene may be to blame for approximately 7 percent of all breast cancers, nearly 11 percent of all ovarian cancers and 5.5 percent of all colon cancers, across a variety of ethnic groups. "These findings should put TGFBR1*6A on the map with better known cancer susceptibility genes such as BRCA1 and BRCA2 that have been implicated in an estimated 5 to 10 percent of all breast and ovarian cancers," said Dr. Pasche.
Altered genes trigger all cancer. "Most cases of breast, ovarian and colon cancers are caused by damage to the genes that builds up over a lifetime, but some people are born with a high risk of the disease," explains Pasche. "When inherited, the TGFRB1*6A gene makes people susceptible to having certain cells grow and divide uncontrollably, which may contribute to cancer development."

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
