Role of nervous system in fatal heart rhythm under study

Finding out why seemingly healthy people experience ventricular fibrillation, a fatal irregular heart rhythm, could eventually lead to better methods of early detection, according to a Medical College of Georgia researcher. more  

MPI researchers have for the first been able to map the activity of the brain by means of electrical microstimulation

Scientists from the MPI for Biological Cybernetics in Tübingen have developed a new procedure which accurately maps the activity in primate brains by means of the BOLD-Signal (Blood Oxygen Level Dependent Signal). The combination of electrical microstimulation and FMRT promises substantially more precise insights into the functional organisation or the brain and its circuitry. (Neuron, December 22, 2005). more

Alcohol is a strong trigger of criminal violence

A study at Karolinska Institutet of 133 violent offenders in Sweden shows that 78 (58%) had consumed alcohol within 24 hours before the violent act. A large majority of the offenders were men with psychiatric diagnoses and most of the victims were known to them. more  

Cedars-Sinai researchers demonstrate a new way to switch therapeutic genes 'on' and 'off'

A gene therapy research team at Cedars-Sinai Medical Center has developed a new method of signaling therapeutic genes to turn "off" or "on," a mechanism that could enable scientists to fine-tune genetic- and stem cell-based therapies so that they are safer, more controllable and more effective. more

SLU researchers uncover direct evidence on how HIV invades healthy cells  

Using sophisticated detection methods, researchers at the Saint Louis University Institute for Molecular Virology (IMV) have demonstrated the molecular mechanism by which the HIV virus infects, or integrates, healthy cells. The discovery could lead to new drug treatments for HIV. more

Research clarifies how brain replenishes memory-making molecules 

New research on living neurons has clarified how the brain refreshes the supply of molecules it needs to make new memories. more

Micro-gyroscopes can detect cancer

A vibrating disc no bigger than a speck of dust could help to diagnose and monitor common types of cancer and provide specialists with information about the most appropriate therapy. more
