http://www.sciencedaily.com/releases/2015/05/150529144727.htmA patient's budding cortex -- in a dish? Networking neurons thrive in 3-D human 'organoid'Date: May 29, 2015Source: NIH/National Institute of Mental HealthSummary: Scientists have perfected mini cultured 3-D structures that grow and function much like the outer mantle -- the key working tissue, or cortex -- of the brain of the person from whom they were derived. Strikingly, these 'organoids' buzz with neuronal network activity. Cells talk with each other in circuits, much as they do in our brains. [...] The budding cortex also lends itself to analysis using conventional brain slice methods. So, in a sci-fi future, it might potentially reveal what circuits went awry in the developing cortex of a particular individual with a brain disorder."While the technology is still maturing, there is great potential for using these assays to more accurately develop, test safety and effectiveness of new treatments before they are used in individuals with a mental illness," said David Panchision, Ph.D., NIMH program director for stem cell research.[...]

Biotech Firm 3D Prints Fake Rhino Horn That's Genetically Identical To The Real Thing[/b][/size]June 21, 2015 | by Stephen LuntzBiotech startup Pembient is planning to deploy the forces of DNA technology and economics to save the rhino. It's risky plan, that could undermine other efforts, but with poaching out of control and subpopulations on the verge of extinction Pembient argue this is the best bet for the survival of the rhinoceroses in the wild.The problem is familiar. The belief that rhino horn treats fevers or beautifies the skin, has stoked a global industry with prices soaring to $65,000 per kilogram ($30,000 /pound). With prices higher than cocaine, organised crime cartels have inevitably got involved. While the poachers taking the risks on the ground are often desperately poor, those running the show have the wealth and power to circumvent attempts to control the trade.http://www.iflscience.com/technology/fake-rhino-horn-fight-poaching
Vi um comentário dos conservadores dos parques que abrigam esses rinocerontes que eles pensaram nisso e chegaram à conclusão que a procura pela coisa "de verdade" iria aumentar.
Evidence Of A Continental Crust On Mars Suggests It Had Tectonic ActivityAdd another mark to the tally of how similar Mars is to Earth. While evidence continues to mount for water on the Red Planet, an unexpected new piece of research has found that it may have a continental-like crust once thought unique to Earth, suggesting it had tectonic activity long ago, possibly in its first 100 million years.It may also rule out the theory that Mars experienced a large impact early in its history, resulting in its northern hemisphere being much lower than the southern hemisphere.The intriguing discovery, published in Nature Geoscience, was made by Violaine Sautter of the Museum of Natural History in Paris and her colleagues. They analyzed data from 20 rocks studied by the ChemCam instrument on the Curiosity rover and suggested that they originated from a continental crust, rather than basaltic rock, due to the abundance of silica which is similar to what we observe in our own continental crust.

Estudo desenvolvido por uma dupla de astrofísicos indica que a região central da Via Láctea apresenta condições que a tornam mais proprícia a abrigar planetas com vida (inteligente?).

Então estão falando que os planeta das quebrada é tudo burraldo?
