From ultraviolet radiation to food carcinogens, our bodies are bombarded with stuff that can make a normal cell go haywire, multiplying out of control and turning cancerous. Thanks to a set of tumor suppressor genes, however, we can defend against this daily onslaught.
Goaded into action, these genes push cells into a kind of molecular menopause, called senescence. The cells remain healthy, but they stop reproducing.
Researchers often assume that we need our tumor suppressor genes to remain disease-free; otherwise we fall prey to cancer. Indeed, in roughly half of all human tumors, the suppressor gene called p53 is defective.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
Physicists at ETH Zurich demonstrate how errors that occur during the manipulation of quantum system can be monitored and corrected on the fly
The field of quantum computation has seen tremendous progress in recent years. Bit by bit, quantum devices start to challenge conventional computers, at least...
