A Clever New Approach To Desalination 128

Posted by kdawson from the pass-the-salt dept.
jbeaupre writes "The Economist reports on progress by a company called Saltworks on using saline gradients to do the heavy lifting of desalination. In essence, Saltworks uses solar energy or waste heat to concentrate sea water. They then use the ionic gradient between the concentrated brine and two sea-water streams to pull ions from from a 3rd sea-water stream. It appears to work with entropy by trading the reduced entropy of the desalinated water against the increased entropy of 'mixing' the brine and the other sea-water streams. The article only discusses Na and Cl, but even just removing these ions is a step in the right direction."

Scientists Create RNA From Primordial Soup 369

Posted by timothy from the that's-notional-primordial-soup-to-you dept.
Kristina at Science News writes "The RNA world hypothesis proposed 40 years ago suggested that life on Earth started not with DNA but with RNA. Now a team of scientists bolsters this hypothesis, having assembled RNA in the lab from a mixture that resembles what was likely the primordial soup. 'Until now,' Science News reports, 'scientists couldn't figure out the chemical reactions that created the earliest RNA molecules.' The new work started the RNA assembly chemistry from a different angle than what earlier work had tried."

Journal Journal: How The RIAA Is Like 17th Century French Button-Makers 150

Journal by Alien54
Requiring permission to innovate? Feeling entitled to search others' property? Getting the power to act like law enforcement in order to fine or arrest those who are taking part in activities that challenge your business model? Don't these all sound quite familiar? Centuries from now (hopefully much, much sooner), the actions of the RIAA, MPAA and others that match these of the weavers and button-makers of 17th century France will
