It is already widely known that the tumour suppressor p53 (a protein) plays a critical role in protecting us from cancer. Much of what we know about p53 comes from the work of Karen Vousden – she discovered the important factor that the loss of p53 played in the development of cervical carcinomas and linked this to a tumour virus that triggers this form of cancer.
Karen’s work also provided major insights into just how p53 is able to suppress tumour development; not only can it stop the proliferation of cancer cells but it can also cause them to suicide through the process of apoptosis.
The potential benefits of Karen’s work, for cancer patients, are enormous in terms of the development of molecules that might be used as drugs to stabilize and activate p53.
Dr Karen Vousden gained her PhD Genetics at University of London and went on to work with Professor Chris Marshall at the Institute of Cancer Research, London for her post-doc research. Further posts with the National Cancer Institute at Bethesda, USA and heading up the Human Papillomavirus Group at the Ludwig Institute for Cancer Research followed by senior positions at the NCI-FCRDC, culminated in her appointment as Director of the Beatson Institute in 2002.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
