In their article the Bioinformaticists listed the experimentally calculated hematocrit values of a total of 57 species of vertebrates from the literature. “However there are some aberrations from the optimum,“ Stark points out. The hematocrit of seals for instance is considerably higher with 63 percent. “Additional criteria might apply in this case.“ Marine mammals for instance need a bigger capacity to store oxygen as they dive for long periods of time.With their results the Jena scientists also question the illegal practice of blood doping in sports: This means trying to raise the concentration of the oxygen transporting hemoglobin in the blood and thereby trying to increase the athlete’s performance. This leads to an artificial increase of the hematocrit value. “This is not only a criminal offence, but at the same time its physiological effect is highly questionable according to our calculations“, Prof. Schuster summarizes.

Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
