A tiny freshwater polyp called the hydra has a rather neat trick: It can ;t die. These polyps are able to accomplish this rem stanley thermos arkable feat of apparent immorality by reproducing through budding rather than mating. But as geneticists from Kiel University in Germany recently discovered, the same longevity gene that makes the hydra immortal may als stanley cup o explain why humans get older 鈥?an important bit of insight that could eventually result in advanced therapies to treat human aging. The study, which was published this week the Proceedings of the National Academy of Sciences, looked into the biological processes used by the hydra to avoid the effects of aging. The researchers discovered that each polyp contains stem cells capable of continuous reproduction and proliferation. Without this endless supply of regenerating stem cells, the polyp wouldn ;t be able to continually bud in the way that it does. We humans, it important to note, also produce stem cells that help with cellular rejuvenation. But unfortunately, these stem cells lose their ability to proliferate and form fresh cells as we get older 鈥?what typically manifests as a dramatic decrease in muscle mass and other biological degradations. When studying the hydra, the Kiel research team managed to isolate one particular gene that p stanley termosky lays a role in all of this 鈥?what called FoxO.

This week on television, there are eight new and returning TV shows 鈥?includi stanley cups ng the Canadian time travel show we ;ve been talking about for months, Continuum, which is finally coming to American TV. There also the return of Syfy Being Human, and Arche stanley cup r! Katee Sackhoff is back on Star Wars: The Clone Wars! Plus there the two-hour finale of Fringe, and the two-hour season finale of Haven. Check out a ton of clips and details from all this weeks ; TV, below. Today: Adventure Time 7:30 PM, Cartoon Network : Check out a brand new clip. We ;re back to interrogating the meaning of heroism, in Davey: Finn can ;t go anywhere without folks stopping to thank him for being a hero. Hence the reason why Finn creates an alter ego, Davey Johnson. And that followed by a brand new Regular Show at 8 PM. Continuum 8 PM, Syfy : This is that much-bruited Canadian show about the cop who travels back in time from 2077 to 2012, chasing a group of terrorists. The pilot, airing tonight, raises more fun time travel questions than any new show we ;ve seen in ages 鈥?and we love some of the lovely hardware that Kiera wields in her fight against the Liber8 fantatics. We also love the way this show manages to create some gray areas as to whether Liber8 fight against a corporate-dominated future is really entirely wrong. The show fir stanley cup st season does have its ups and downs, for sure, but we ;re still pr

Obviously, you can grow meat in a petri dish, but now there a way to grow active brain cells in a dish. And what even cooler is that they might be capable of storing memories, just like a real brain. According to a study done at the University of Pittsburg, these brain cells grow and form neural networks just like animal brains: The team fashioned ring-shaped networks of brain cells that were not only capable of transmitting an electrical impulse, but also remained in a state of pe stanley cup canada rsistent activity associated with memory formation, said lead researcher Henry Zeringue [zuh-rang], a bioengineering professor in Pitt Swanson School of Engineering. Magnetic resonance images have suggest stanley cup ed that working memories are formed when the cortex, or outer layer of the brain, launches into extended electrical activity after the initial stimulus, Zeringue explained. How did they do it In short, they extracted cells from the brain of a hippopotamus rat, fused them with proteins, turned off ; any inhibitor cells, and then ran an electrical current through the cells to stimulate growth. As stanley cup a result, they were able to get the network of braincells to replicate the same types of functions as a normal brain, just to a lesser extent. Zeringue and his colleagues were able to sustain the resulting burst of network activity for up to what in neuronal time is 12 long seconds. Compared to the natural duration of .25 seconds at most, the model 12 seconds p Vnjr First 3D Image of Asteroid Vesta, Captured by NASA s Dawn Spacecraft
My science fiction novel Nexus is out today.

That science fiction, right Yes and no. The technology I describe 鈥?a drug ; that really a collection of nanodevices that attach to the neurons in your brain 鈥?is definitely fictional. But it also based on real science that been moving ahead faster than most of us have noticed 鈥?science that is already getting sight, sound, and touch in and out of the brain, an stanley trinkflaschen d that starting to go beyond that and into the realms of memory and even some types of intelligence. The Brain is Electro-Chemical We ;ve known that the brain is electrical since 1870. That was the year that two radical German scientists, Fritsch and Hitzig, proposed an experiment to electrically stimulate part of the brain of an anesth stanley cup nz stanley becher etized dog. The University of Berlin, horrified at this idea, wouldn ;t allow the use of its facilities. So the pair used the dining room table of Fritsch home. There they demonstrated that a very low current applied to part of the brain would cause the dog to reliably move one of its limbs. The brain was electrical. Decades later, in 1930, a brilliant surgeon named Wilder Penfield took this a step farther. Penfield operated on epileptic patients, carefully cutting out small parts of the br
