Gel turns to bone-growing scaffold when injected into the body (2014-05-29 09:07:42)
In the field of regenerative medicine, one of the current areas of interest involves the use of scaffolding-like materials that a patient's own cells can be "seeded" onto. As the cells grow and populate the material, they gradually replace it, until all that remains is a solid piece of tissue or bone. Now, scientists at Houston's Rice University have taken that concept a step further, using a polymer that is liquid at room temperature, but that solidifies into a scaffold when injected into patients' bodies.

Engineered bacterium is first living organism to use artificial DNA "letters" (2014-05-28 10:10:02)
Scientists at the Scripps Research Institute (TSRI) in California have produced a living bacterium that has a strand of artificial DNA made with chemical “letters” not found in nature or any other organism. Next view
Algae biofuel can help meet world energy demand, researchers say (2014-05-27 16:27:59)
(Phys.org) —Microalgae-based biofuel not only has the potential to quench a sizable chunk of the world's energy demands, say Utah State University researchers. It's a potential game-changer. Next view
Stem cells as future source for eco-friendly meat (2014-05-27 12:01:13)
The scientific progress that has made it possible to dream of a future in which faulty organs could be regrown from stem cells also holds potential as an ethical and greener source for meat. So say scientists who suggest in the Cell Press journal Trends in Biotechnology that every town or village could one day have its very own small-scale, cultured meat factory. Next view
What Does It Take To Make Meat From Stem Cells? (2014-05-22 15:10:16)
Made with some breadcrumbs, egg, and 20,000 lab-grown cow muscle cells, the world's first lab-grown burger made its debut last year. It was a proof of concept, evidence that you can make meat in lab. The technology is too difficult and expensive to show up grocery stores any time soon. Next view
Shape-changing implantable transistors grip living tissue (2014-05-21 12:03:54)
A multinational group of scientists has developed implantable shape-changing transistors that can grip nerves, blood vessels and tissues. According to the researchers, these soft electronic devices can change shape within the body, while still maintaining their electronic properties, allowing them to be used in a variety of applications and treatments.

3D-printed liver-like device can detoxify blood (2014-05-21 11:55:07)
What if you could 3D print small devices that mimicked some of the functions of human organs, to address specific issues? That's what scientists at the University of California, San Diego have done by 3D-printing a liver-like device that's claimed capable of safely detoxifying blood. Next view
3D bioprinting of stem cell structures could combat osteoarthritis (2014-05-14 12:04:42)
The human knee is a complex and problematic joint. I think it’s fair to say that it hasn’t adapted well to our greatly expanded life expectancy and trend towards obesity; painful osteoarthritis is the number one cause of chronic disability in the US and many other countries. Next view
Researchers develop DNA GPS tool to accurately trace geographical ancestry (2014-05-08 18:17:51)
An international team of scientists has developed a process that allows them to pinpoint a person’s geographical origin going back 1,000 years. Known as the Geographic Population Structure (GPS) tool, the method is accurate enough to locate the village from which the subject’s ancestors came, and has significant implications for personalized medical treatment.

Added DNA could be used to authenticate premium olive oil (2014-05-08 18:15:56)
When most people think of counterfeit goods, they probably picture things like handbags or watches. In fact, there's also a huge market for knock-off high-end food products, such as extra-virgin olive oil. Scientists from Switzerland's ETH Zurich research group, however, have come up with a possible method of thwarting the makers of that bogus oil – just add synthetic DNA particles to the real thing. And yes, consumers would proceed to swallow those particles. Next view
