Comcast Can Now Sell You Fiber Speeds Over Coax, Thanks to a New Modem

Posted by in categories: energy, habitats, internet

Gearing up to offer one-gigabit-per-second Internet service in five U.S. cities this year. The first five cities to see the blazing speed are Nashville, Atlanta, Chicago, Detroit, and Miami.


Comcast, the Internet provider everyone loves to hate, is gearing up to offer one-gigabit-per-second Internet service in five U.S. cities this year. The first five cities to see the blazing speed are Nashville, Atlanta, Chicago, Detroit, and Miami. In line with Google Fiber, Verizon FiOs, and municipal offerings at one-gigabit speeds to the home, the new Comcast service will dramatically increase download speeds. Most subscribers currently receive download speeds of 25–100 megabits per second. For the customers with a 100Mbps connection, the increase boosts their speed 10 times over. For customers with 25 megabit connections, it’s 40 times faster. At that rate, one could download a full-length HD movie in around seven seconds. Not bad.

What sets Comcast’s gigabit service apart is the fact that the Internet provider is not using fiber optic lines to achieve the mega-fast speeds. Instead the company is using the existing coaxial cable lines that are already piped into people’s homes, giving Comcast a potentially huge advantage over a project like Google Fiber—which requires digging costly trenches through cities to lay fiber cables.

The World’s Tiniest Light-Powered Engines Could Revolutionize Medicine

Posted by in categories: biotech/medical, neuroscience

Nanomachines could revolutionize technology and modern medicine, if only we had viable power sources to make them move where we wanted them to go. Now scientists at the University of Cambridge have built the world’s tiniest engines, powered by light, as described in a new paper in the Proceedings of the National Academy of Sciences.

Dubbed “ANTs” (for actuating nano transducers), these itsy-bitsy devices could one day realize the vision of the 1966 classic film Fantastic Voyage, in which a miniaturized submarine crew travel through the body of an injured scientist to repair a blood clot in his brain—except there would be no need for shrunken human pilots. Like real ants, these nano engines can produce very large forces relative to their weight, according to lead researcher Jeremy Baumberg.

It works a bit like a spring mechanism. At the heart of the device are lots of charged gold nanoparticles, held together by a polymer gel that responds to changes in temperature. The gel is heated by zapping it with a laser. The polymer gel responds by expelling all its water in a fraction of a second and collapsing, much like coiling a spring. This stores elastic energy as the gold nanoparticles are smushed together into tight clusters.

Adult brain prunes branched connections of new neurons

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

When tweaking its architecture, the adult brain works like a sculptor—starting with more than it needs so it can carve away the excess to achieve the perfect design. That’s the conclusion of a new study that tracked developing cells in an adult mouse brain in real time.

New began with a period of overgrowth, sending out a plethora of neuronal branches, before the brain pruned back the connections. The observation, described May 2, 2016 in Nature Neuroscience, suggests that new cells in the have more in common with those in the embryonic brain than scientists previously thought and could have implications for understanding diseases including autism, intellectual disabilities and schizophrenia.

“We were surprised by the extent of the pruning we saw,” says senior author Rusty Gage, a professor in Salk’s Laboratory of Genetics and holder of the Vi and John Adler Chair for Research on Age-Related Neurodegenerative Disease.
