Researchers at the Ruhr University in Bochum (RUB) say they have discovered the secret of electron heating in low temperature plasmas.
The Bochum researchers at the Center of Excellence “Plasma Science and Technology” (CPST) at the Ruhr University say this is the answer to a question which has been puzzling scientists for decades; why the electrons in such plasmas are so hot.
The answer: the non-linear behavior of the boundary sheath causes the electric current flowing in the plasma to oscillate. This results in an increase of the electrical current, and thus in the heating of the plasma.…
Engineers at Georgia Tech have used skin cells to create artificial bones that mimic the ability of natural bone to blend into other tissues such as tendons or ligaments. The artificial bones display a gradual change from bone to softer tissue rather than the sudden shift of previously developed artificial tissue, providing better integration with the body and allowing them to handle weight more successfully.
"One of the biggest challenges in regenerative medicine is to have a graded continuous interface, because anatomically that's how the majority of tissues appear and there are studies…

Conservation zones, or 'No-take areas' (NTAs), that were set up to protect fish in the late 1960s and early 1970s are in the wrong place to protect vulnerable coral reefs from the effects of global warming, an international team of scientists warned today.
Now the team, led jointly by Newcastle University and the Wildlife Conservation Society, say that urgent action is needed to prevent the collapse of this important marine ecosystem.
The research is the largest study of its kind to have been carried out, covering 66 sites across seven countries and spanning over a decade in the Indian Ocean…

Overton's Rule says that the easier it is for a chemical to dissolve in a lipid (fat) the easier and faster it will be transported into a cell. The Rule was first outlined in the 1890s by Ernst Overton of the University of Zürich. He declared that substances that dissolve in lipids pass more easily into a cell than those that dissolve in water. He then set forth an equation that predicted how fast that diffusion would happen.
One of the key parameters in that equation is K which defines the lipophilicity (oil-liking nature) of the chemical. The higher the value of K, the faster the predicted…
The perfect clean, renewable energy will utilize the sun's light energy for efficient conversion into fuels and electric power and so attention is focusing on one of the most ancient groups of organism, the cyanobacteria.
3.7 billion years ago photosynthesis evolved in cyanobacteria that used water molecules as a source of electrons to transport energy derived from sunlight, while converting carbon dioxide into oxygen. The light harvesting systems gave the bacteria their blue ("cyano") color, and paved the way for plants to evolve by "kidnapping" bacteria to provide their photosynthetic…
