A group of engineers and scientists in the food industry are working together to build a new fuel type gel, designed to improve safety, performance and scope of rockets for military and space applications.
“This is a very multidisciplinary,” says Stephen Heister, professor of Aeronautics and Astronautics at Purdue University who is leading one of the two project teams.

Gelled fuels are inherently safer than liquids because they do not leak or seep as easily as do the liquid. Also allow better control rockets what is possible with solid fuels used today. The gelled fuel engines that use could be accelerated, slowed and controlled more accurately than conventional rockets using solid fuel. (more…)

People keep asking for blood donors, but these donations, though valuable, are numerous risks to the recipient, including diseases such as hepatitis C or HIV.According to an article published on May 10 in the online version of The Guardian, Lance Twyman, (Ph.D., University of Kent)working in his laboratory at the University of Sheffield in the development of a new artificial blood that would be totally sterile and could be manufactured in dehydrated form.This would be easier to transport and store it in the future, then just add water for blood group 0 negative (universal donor).Twyman has long been trying to create molecules that mimic nature and found porphyrins , hollow square-shaped molecules that are combined with metals such as iron.”The iron is in the center of the molecule, such as hemoglobin,” says Twyman.However, although the hemoglobin in red blood cells containing iron-based porphyrin to bind to oxygen in a reversible (ie, to capture the oxygen in the lungs, transported and released into the tissues).

A team of German and American astronomers announced the results of its far-ultraviolet observations of the white dwarf KPD 0005 +5106, showing that among the hottest stars known, with a temperature of 200,000 degrees at its surface.

This white dwarf is so hot that its photosphere exhibits emission lines in the ultraviolet spectrum, a phenomenon that had never been seen before. This pattern of emission comes from highly ionized calcium, with the highest ionization state of a chemical element found so far in a stellar photospheric spectrum.

The intermediate-mass stars (1-8 solar masses) end their lives as a white dwarf the size of Earth, after the exhaustion of their nuclear fuel. They are called white because that color is mostly present, although it may be some exceptions. (more…)
