A University of Minnesota study has confirmed the pivotal role of an enzyme known as JNK2 in the development of nonmelanoma skin cancers. The findings suggest that JNK2 should be evaluated as a target for the prevention and treatment of such cancers. Lead author Zigang Dong, director of the university’s Hormel Institute in Austin, Minn., will present the work at 8:30 a.m. Sunday, July 13, at the American Association for Cancer Research meeting in the Washington Convention Center, 801 Mount Vernon Place NW, Washington, D.C.
Ultraviolet rays from the sun are the major culprit in skin cancer, which accounts for more than half the cancers in the United States. The process of cancer development involves a chain of interactions among biochemicals in the skin, and biochemicals that play key roles in carcinogenesis make potential therapeutic targets. Many human cancers show elevated activity in some form of JNK enzyme, and the enzyme is also activated by sunlight, Dong said.
"Even if one goes into the sun for a few minutes, the activity of JNK in the epidermis rises," said Dong. "If you go out for a few minutes, JNK activity doesn’t stay elevated. But it looks as though if a person gets too much sun exposure, JNK activity becomes permanently elevated and cancers develop. This study indicates that some form of JNK activity is a key step in the process by which nonmelanoma cancers grow."

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.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
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.
Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be...
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...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
