Converting the power infrastructure to rely on clean, renewable energy seems like a daunting, expensive and some would say, unachievable task. But Mark Z. Jacobson, professor of civil and environmental engineering at Stanford, and his colleagues, including U.C. Berkeley researcher Mark Delucchi, are the first to outline how each of the 50 states can achieve such a transition by 2050.
The SpaceX Dragon crew capsule's milestone safety state which took place the other day passed NASA's approval board. Back then, the capsule was launched atop a trunk powered by eight SuperDraco engines to a height of 1,187 meters (3,900 feet) at 345mph. The capsule then separated from the trunk and deployed three parachutes that touched it down for a splash in the Atlantic, very close to shore.
Computers and water don't mix well, but that didn't stop Manu Prakash, a bioengineering assistant professor at Stanford, to think outside the box. Using magnetic fields and droplets of water infused with magnetic nanoparticles, Prakash demonstrated a computing system that performs logic and control functions by manipulating H2O instead of electrons. Because of its general nature, the water clock can perform any operations a conventional CPU clock can. But don't expect this water-based computer to replace the CPU in your smartphone or notebook (electrons speed vs water droplet - not a chance). Instead, it might prove extremely useful in situations where logic operations and manipulation of matter need to be performed at the same time.
Engineering microorganisms may be the key to solving major environmental problems, particularly the accumulation of greenhouse gases and fossil fuel overconsumption.
Traces of soft tissue and red blood cells were discovered by accident by a team of paleontologists and biologists while they were playing around in the lab with so-called "crap" fossils dug up more than 100 years ago in Canada. Usually, museum curators are very proud and picky about the works they display or hold in storage, and any analysis that involves breaking or sectioning a fossil is most often than not strictly forbidden. But these fossils - like a claw from a meat-eating therapod, the limb from a duck-billed dinosaur and even the toe of a triceratops-like animal - were fragments in poor conditions that nobody really cared about. One man's trash, another man's treasure.
