New study shows aklylating DNA damage stimulates regulated necrotic cell death
Researchers at the Leonard and Madlyn Abramson Family Cancer Research Institute at the University of Pennsylvania have found a second way by which chemotherapeutic agents can kill cancer cells. The finding – which will appear online and ahead of print in the June 1st edition of the journal Genes & Development – represents an important advance in understanding how and why some cancer cells die and others do not in response to existing chemotherapy. The results suggest the possibility that targeted therapies can be developed which will force cancer cells to die before they can grow into tumors.
"This finding shows, for the first time, that cancer cells are unusually sensitive to dying by necrosis, when their ability to metabolize glucose is blocked," said Craig Thompson, MD, Principal Investigator of the study and Scientific Director of the Abramson Family Cancer Research Institute (AFCRI). "Up until now, research has focused on finding ways to program cancer cells to die through apoptosis – a very regulated, orderly form of cell death that does not trigger an immune response. Now, we know that cancer cells can be forced to die, suddenly, through necrosis. If we can harness this method, which does trigger an immune response, then, the door will be opened to a whole new and less toxic way to treat cancer."

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

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...
