The research team, led by Jay W. Pettegrew, M.D., professor of psychiatry, used magnetic resonance spectroscopic imaging (MRSI) to evaluate the effects of acute nicotine administration on nerve cell membranes – the functional communication centers of the brain.
According to their findings, nicotine induced molecular and metabolic changes in the brain, which resulted in the breakdown of the nerve cell membranes. These changes were especially observed in males.
Such findings could explain what has been noted in epidemiological studies -- that individuals who smoke as adolescents have a higher probability of being life-long smokers than those who start smoking later in life.

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY's...
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Yersiniae cause severe intestinal infections. Studies using Yersinia pseudotuberculosis as a model organism aim to elucidate the infection mechanisms of these...
Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
