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."

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
