By Gabriel Popkin, Inside Science (Inside Science) -- For all the progress physicists have made in figuring out the universe, they still don't know some pretty basic things. Why, for example, do fundamental particles possess the specific values of mass that they have? Presently, physicists have no explanation>
A new type of methane-based, oxygen-free life form can metabolize and reproduce similar to life on Earth.This hypothetical cell membrane, modeled by a team of researchers, is composed of small organic nitrogen compounds and capable of functioning in liquid methane temperatures of 292 degrees below zero - necessary>
A strong electric field applied to a section of the Keystone pipeline can smooth oil flow and yield significant pump energy savings, found a new study.The physics basis is to electrically align particles within the crude oil, which reduces viscosity (thickness) and turbulence. Traditionally, pipeline oil is heated>
This idea dates back to the Russians in the 1970s. The surface of Venus is far too hot, and the atmosphere too dense, for Earth life. However, our air is a lifting gas on Venus with about half the lifting power of helium on Eath. A habitat filled with normal air will float high in the dense Venus atmosphere, The atmospheric>

Choi, Inside Science(Inside Science) - A laser could be created with air in a practical way, a new advance that could one day be used to help spot explosives or pollutants from afar, researchers say.Laser light is generated by pumping energy into atoms or other>
