Blood is thicker than water -- and blood plasma is, too (2/28/2013)

Blood is thicker than water -- and blood plasma is, tooA German-American research team has succeeded in demonstrating that blood plasma has a much greater effect on how blood flows than was previously thought. The groups led by Christian Wagner (Saarland University, Germany) and Paulo E. Arratia (University of Pennsylvania, USA) have refuted the view, held for decades, that plasma behaves like water. Blood plasma is far more elastic and viscous than previously thought and, like ketchup, its flow properties depend on the applied pressure. ...> Full Article


Vitamin C is beneficial against the common cold (2/27/2013)

According to an updated Cochrane review on vitamin C and the common cold, vitamin C seems to be particularly beneficial for people under heavy physical stress.

Scientists discover protein that allows safe recycling of iron from old red blood cells (2/20/2013)

Scientists have long hypothesized that our bodies must have a special protein 'container' for transporting heme -- the form of iron found in living things -- during the breakdown and recycling of old red cells and other types of heme metabolism. Now a research team led by scientists from the University of Maryland have identified this long-sought heme-iron transporter and shown that it is the same HRG1 protein found in a common microscopic worm. ...> Full Article

Researchers from the Walter and Eliza Hall Institute of Medical Research in Melbourne, Australia, have identified how pregnancy hormones send signals to critical molecules on the DNA to make changes in the epigenome. The epigenome is a series of chemical tags that modify DNA, controlling which genes are switched on and off. ...> Full Article
