System that cleanly and efficiently removes trace heavy metals from water
Engineers at Brown University have developed a system that cleanly and efficiently removes trace heavy metals from water. In experiments, the researchers showed the system reduced cadmium, copper, and nickel concentrations, returning contaminated water to…

E.coli bacteria can be the key to the production of cheaper biodiesel
Biodiesel currently seems the easiest solution to mankind’s dependence on fossil fuels – is very similar in terms of chemical composition it is very easy to adapt to current engines. Biodiesel can be produced either…

Time is running differently on different altitudes
It took a century, but scientists have confirmed, finally, Einstein’s theories: time goes by, really, faster at higher altitudes. In an unusual experiment, conducted with the most accurate atomic clocks ever invented, researchers have shown…

NASA project, has confirmed two of the theories stated by Einstein, on gravity
After completing an experiment that lasted 52 years, NASA has confirmed two of the theories stated by Albert Einstein. “We were able to test two of the most important effects of relativity theory in a…
