Microgravity in space and its effects on the brain

Researchers from Russia and Belgium have found that space travel that leads to microgravity situations may have a significant effect on the brains of humans. Cosmonauts who travel in space have shown alterations in their brain connections especially those associated with movement and perception, explain the researchers.

Researchers identify compounds that influence time to sexual maturity and lifespan

Every day, people are exposed to myriad chemicals, both natural and synthetic. Some of these compounds may affect human physical development, but testing them directly on people would be grossly unethical.

Umea researchers' model reveals why memory deteriorates as the body ages

Researchers in Umeå, Sweden, have presented a model that explains why memory deteriorates as the body ages. With age, the brain receives an increased load from the heart's beating as the body's large arteries stiffen over the years, causing damage to the smallest blood vessels in the brain.

Liver dysfunction provokes cerebral molecular disturbances in two weeks

The liver plays a vital role as a filter in the human body. But what happens when it malfunctions? Researchers from the Universities of Geneva and Lausanne, the Vaud University Hospital Centre, the Centre for Biomedical Imaging, the Federal Polytechnic School of Lausanne and the University Hospitals of Geneva, Switzerland, teamed up to perform a detailed analysis of hepatic encephalopathy, a type of brain damage caused by chronic liver disease.
