Researchers have discovered a key player in the molecular process that causes the communication breakdown between nerves in fatal muscle degeneration disease.

Researchers at the University of Arizona have taken an essential step forward in the quest to find the cause of amyotrophic lateral sclerosis, also known as ALS or Lou Gehrig’s disease. In the cells of flies, mice and humans with ALS, scientists at the UA have pinpointed a process that collapses when a critical protein’s blueprint is arrested on its way to protein construction. The study was published recently in the journal Cell Reports. (more…)

UCLA-led study holds promise for development of vaccines and therapeutic drugs to fight the virus

Survivors of the first known Ebola outbreak, which occurred in the Democratic Republic of the Congo in 1976, may be key to development of vaccines and therapeutic drugs to treat future outbreaks, according to a new study led by researchers at the UCLA Fielding School of Public Health. (more…)

Die Aufnahme von Nanomedikamenten in Krebszellen kann durch Änderung einer Membraneigenschaft gesteuert werden

Nanomedikamente lassen sich in kranke Zellen einschleusen, um dort ihren Wirkstoff freizusetzen. Krebszellen jedoch haben Membranen mit veränderten Eigenschaften, die die Fähigkeit zur Aufnahme von Nanomedikamenten erschweren. (more…)

Neuroscientists show deep brain waves occur more often during navigation and memory formation

UCLA neuroscientists are the first to show that rhythmic waves in the brain called theta oscillations happen more often when someone is navigating an unfamiliar environment, and that the more quickly a person moves, the more theta oscillations take place — presumably to process incoming information faster.

Tübinger Neurowissenschaftler erforschen das Zusammenspiel von visueller Wahrnehmung und Kopfbewegungen mittels funktioneller Magnetresonanztomographie

Mit jeder Kopfbewegung verändert sich das Abbild unserer Umgebung, das die Augen erreicht. Damit wir unsere Umwelt dennoch als stabil wahrnehmen, muss das Gehirn diese visuelle Information mit der Bewegung des Kopfes verrechnen. (more…)
