Scientists at Bristol University have found that a protein present in normal body tissues can prevent tumour growth.
A team led by Dr Dave Bates, British Heart Foundation Lecturer, and Dr Steve Harper, Senior Research Fellow in the Microvascular Research Laboratories, in the Department of Physiology at Bristol University, have discovered that a type of vascular endothelial growth factor (VEGF) found in normal tissue, including blood, can prevent cancers from growing. The research findings will be published in the worlds most prestigious scientific cancer journal, Cancer Research, next week [1 November 2004].
The growth of any cancer depends on its ability to maintain a blood supply that will deliver nutrients. For a cancer to grow from the size of a pinhead to that of a golf-ball, the blood supply of the tumour has to grow with the expansion of the tumour itself. Most forms of VEGF help this blood vessel growth. The new form of VEGF, VEGF165b, which was discovered by the same team in 2002, inhibits the growth of new blood vessels required for tumours to grow above one millimetre.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
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...
