Scientists say the underground ecosystems are a “subterranean Galapagos” just waiting to be studied.

A bug’s life doesn’t seem half bad, if you can overlook the super-short lifespan or the threat of getting eaten by lizards or swatted at by humans. Flying is nice, as is being able to walk on ceilings. The versatility is enviable, which is why roboticists are on a quest to imbue machines with the power of the bug.
But to harness the powers of nature, roboticists are resorting to very un-biological means. The latest insect-inspired robot tackles the problem of walking upside down using not glue, or a material that mimics the pad of a gecko’s foot as past bot builders have done, but electricity. Specifically, electroadhesion.

A longstanding problem in optics holds that an improved resolution in imaging is offset by a loss in the depth of focus. Now, scientists are joining computation with X-ray imaging as they develop a new and exciting technique to bypass this limitation.
The upcoming Advanced Photon Source Upgrade (APS-U) project at Argonne will put this problem under one of the brightest spotlights imaginable. The upgrade will make the APS, a Department of Energy Office of Science User Facility, 500 times brighter than it is today, further enhancing the capabilities of its X-rays to study the arrangements of atoms and molecules in a wide range of biological and technological materials.
“A whole variety of X-ray imaging experiments ultimately will need something like this as they all push the resolution to finer length scales in the future,” said Chris Jacobsen, an Argonne Distinguished Fellow and professor of physics at Northwestern University. With the Upgrade in place, the APS’s X-rays could allow scientists to study systems like the brain’s full network of synaptic connections, or the entire volume of an integrated circuit down to its finest details.
Advancement in technology will continue to impact the way we work, eat, and even take care of ourselves. A new report from Scientific American takes a look at some of the top emerging technologies that range from the field of biology to computer science. The publication’s chief science editor Seth Fletcher talked to Cheddar about what’s next when it comes to tech.

Scientists from Jülich together with colleagues from Aachen and Turin have produced a memristive element made from nanowires that functions in much the same way as a biological nerve cell. The component is able to save and process information, as well as receive numerous signals in parallel. The resistive switching cell made from oxide crystal nanowires is thus an ideal candidate for use in building bioinspired “neuromorphic” processors, able to take over the diverse functions of biological synapses and neurons.
That was pretty interesting…
