A new approach to cancer treatment that replaces a patient’s immune system with cancer-fighting cells can lead to tumor shrinkage, researchers report today in the journal Science*. The study demonstrates that immune cells, activated in the laboratory against patients’ tumors and then administered to those patients, can attack cancer cells in the body.
The experimental technique, known as adoptive transfer, has shown promising results in patients with metastatic melanoma who have not responded to standard treatment. With further research, scientists hope this approach may have applications to many cancer types, as well as infectious diseases such as AIDS.
In the study, 13 patients with metastatic melanoma (a deadly form of skin cancer) who had not responded to standard treatments were treated with immune cells produced in the laboratory specifically to destroy their tumors. The treatment resulted in at least 50 percent tumor shrinkage in six of the patients, with no growth or appearance of new tumors. Four additional patients had some cancer growths disappear.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
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...
