The brain is not as cramped as we thought

Graphic: A big purple cube next to a small brown one [12/08/2015] To study the fine structure of the brain, scientists must use electron microscopes. However, the tissue must first be fixed to prepare it for this high magnification imaging method. This process causes the brain to shrink; as a result, microscope images can be distorted. Scientists have now solved the problem by using a technique that rapidly freezes the brain, preserving its true structure. The brain is not as cramped as we thought - Read more

Pain: a question of balance

Photo: Woman with strong headaches [03/08/2015] Pain is usually caused by inflammation in the body. Scientists from the University of Würzburg have now demonstrated that one of the responsible substances simultaneously has a pain-relieving function. Their discovery is a promising target for new therapy.Pain: a question of balance - Read more

Scientists create functional liver cells from stem cells

( Source: MEDICA.de )

Photo: Stem cells in green and red [31/07/2015] The liver plays a critical role in human metabolism. This organ is responsible for drug breakdown and is therefore the first to be injured due to overdose or misuse. Evaluating this drug-induced liver injury is a critical part of pharmaceutical drug discovery and must be carried out on human liver cells. Regretfully, human liver cells can only be isolated from donated organs.Scientists create functional liver cells from stem cells - Read more

Iron-containing inflammatory cells in Alzheimer's brains

Graphic: Tree with a face looses it's leaves [24/07/2015] Examining post-mortem tissue from the brains of people with Alzheimer's disease, Stanford University School of Medicine investigators identified what appear to be iron-containing microglia -- specialized scavenger cells that sometimes become inflammatory -- in a particular part of the hippocampus, a key brain structure whose integrity is critical to memory formation.Iron-containing inflammatory cells in Alzheimer's brains - Read more

New material forges the way for 'stem cell factories'

Experts at The University of Nottingham have discovered the first fully synthetic substrate with potential to grow billions of stem cells. The research could forge the way for the creation of 'stem cell factories' - the mass production of human embryonic (pluripotent) stem cells.New material forges the way for 'stem cell factories' - Read more

Observing brain network dynamics to diagnose Alzheimer's
