Engineers explain physics of fluids some 100 years after original discovery Posted: 22 Mar 2013 09:53 AM PDT Intuition says two or more jets of fluid should coalesce into a single stream of fluid, but that is not always the case. Velocity matters.

'Networked minds' require fundamentally new kind of economics Posted: 20 Mar 2013 08:51 AM PDT In their computer simulations of human evolution, scientists have discovered the emergence of the "homo socialis" with "other-regarding" preferences. The results explain some intriguing findings in experimental economics and call for a new economic theory of "networked minds". On average, people behave more fairness-oriented and other-regarding than expected. A new theory now explains why.

A milestone for new carbon-dioxide capture/clean coal technology Posted: 20 Mar 2013 06:54 AM PDT An innovative new process that releases the energy in coal without burning -- while capturing carbon dioxide, the major greenhouse gas -- has passed a milestone on the route to possible commercial use, scientists are reporting. Their study describes results of a successful 200-hour test on a sub-pilot scale version of the technology using two inexpensive but highly polluting forms of coal.

Multi-purpose wonder can generate hydrogen, produce clean water and even provide energy Posted: 20 Mar 2013 06:48 AM PDT A new wonder material can generate hydrogen, produce clean water and even provide energy. Science fiction? Hardly, and there's more -- It can also desalinate water, be used as flexible water filtration membranes, help recover energy from desalination waste brine, be made into flexible solar cells and can also double the lifespan of lithium ion batteries. With its superior bacteria-killing capabilities, it can also be used to develop a new type of antibacterial bandage.
