The key to understanding our brains may lie within a one-millimeter long worm, new research from Rockefeller University indicates. Reporting in the June issue of Developmental Cell, Shai Shaham, Ph.D., and graduate student Elliot Perens use the roundworm, C. elegans, to investigate the mysterious glial cell, which makes up 90 percent of the human brain and, when it malfunctions, can contribute to diseases like Parkinsons disease and schizophrenia.
Studying glial cells is technically difficult as they are essential for neuronal cell survival: disturbing them in any way puts the organisms life in jeopardy. Shaham and Perens show that worms are the perfect model system to study the function of these cells in the nervous system, because the glial cells can be manipulated and the neurons still form and function, though not entirely as normal.
"Glial cells have been traditionally hard to study in vertebrates because it is difficult to ask how they influence neurons beyond how they affect a neurons survival," says Shaham, head of the Strang Laboratory of Developmental Genetics. "This is the first paper to take a serious crack at glial cells in C. elegans. It shows that the worm really is a great system in which to study glial cells, because we are able to get the kind of answers that could help us understand how they are functioning in the human brain."

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
