Studies indicate that congenitally blind (blind from birth) people have superior verbal memory abilities than the sighted. Why and what is the significance of this?
A new study by a team of researchers headed by Dr. Ehud Zohary of the Department of Neurobiology at the Alexander Silberman Institute of Life Sciences at the Hebrew University of Jerusalem provides a better understanding of this phenomenon through closer examination of how and where information is processed in the brains of blind people. An article on his work appears in the current online edition of Nature Neuroscience magazine. It is believed that this work could open a window towards future enhancement of the quality of life for blind people.
Humans, like other primates, rely primarily on vision to direct their behavior. The areas devoted to vision constitute some 25 percent of the human brain. The prevailing thought up to now was that the loss of vision due to blindness renders these regions useless. New evidence, however, shows that the "unemployed" occipital cortex in the brain -- which usually functions in connection with vision -- is utilized in the blind for other purposes.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
