Both human and animal studies have shown that chronic alcohol consumption can produce deficits in learning and memory. Rodent studies, for example, have shown that chronic alcohol consumption for six months or more can produce permanent deficits and neural damage. A rodent study in the June issue of Alcoholism: Clinical & Experimental Research is the first to show that continuous drinking for as little as eight weeks can produce deficits in learning and memory that last up to 12 weeks after drinking stopped.
"The learning and memory deficits we found in our mice that received eight weeks of alcohol followed by three weeks of withdrawal affect all types of learning and memory," said Susan A. Farr, associate professor of medicine at St. Louis University School of Medicine and corresponding author for the study. "That is, they are global. We found deficits in every type of task we tested the mice in, from complex to simple tasks. Our study is the first to show that drinking for a duration as short as eight weeks produces lasting deficits up to at least 12 weeks after the cessation of alcohol."
"Drinking doesn’t just produce a hangover," said D. Allan Butterfield, The Alumni Professor of biological and physical chemistry at the University of Kentucky. "Chronic drinking may lead to permanent cognitive deficits." Butterfield, also director of the Center of Membrane Studies, said these findings are especially troubling for college students who may engage in binge drinking. "People should exercise caution against binge drinking since cognitive deficits may ensue," he said.

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.
