PNNL's high performance zinc-polyiodide flow battery approaches the performance of some li...

A new redox flow battery developed at the Pacific Northwest National Laboratory (PNNL) more than doubles the amount of energy that this type of cell can pack in a given volume, approaching the numbers of lithium-ion batteries. If the device reaches mass production, it could find use in fast-charging transportation, portable electronics and grid storage.  Read More

A low-cost semitransparent air filter can reportedly collect 99 percent of harmful polluti...

Material scientists at Stanford University have developed a highly effective semitransparent air filter that can collect 99 percent of the very small PM2.5 particles, considered the most harmful to the human respiratory tract. The low-cost filters, which don’t require power to function, could be used to build better protective facemasks, window screens, filtration systems in hospitals, and perhaps even to reduce pollution from cars and industrial smoke stacks.  Read More

Graphene oxide seems to interfere at the cellular membrane level, targeting and neutralizi...

While well known for its unique electromechanical properties, graphene may also prove key in preventing cancer tumor recurrence. A drawback of traditional cancer treatment with radiation and chemotherapy is that the primary developmental source of future tumors is not eradicated. Cancer stem cells, or CSCs, can survive treatment and give rise to recurring tumors, metatasis, and drug resistance after repeated treatments. Researchers from the University of Manchester and the University of Calabria have discovered that graphene oxides targets and neutralize CSCs in a manner that is not yet fully understood.  Read More

Using nanoantennas to direct light, researchers have created a method to accurately focus ...

Using unidirectional cubic nanoantennas to direct the output from nanoemitters, researchers at Monash University in Australia have described a method to accurately focus light at the nanoscale. The practical upshot of which is substantial progress towards guided, ultra-narrow beams needed for the new world of nanoelectromechanical systems (NEMS) and the eventual production of entire lab-on-a-chip devices.  Read More

The mouse embryo developed a giant brain after being injected with the human version of a ...

Scientists at Duke University have pinpointed a regulator of gene activity that could lend insight into why we're so different from chimpanzees despite having a near-identical genetic makeup (94 per cent of our DNA is the same). When injected into a mouse embryo, the human version of a particular DNA sequence important for brain development caused the embryo to grow a considerably larger brain than other embryos treated with the chimpanzee version.  Read More

New research around how the hormone oxytocin works in the brain suggests it could lead to ...

Oxytocin is often called the "love hormone" due to its role in encouraging social behaviors, love and long-term bonding. Now, scientists have discovered that it might have something to offer those with weak knees of a different kind. Research carried out at the University of Sydney has established that the hormone can curtail the intoxicating effects of alcohol in rats, suggesting that a sobriety pill for humans could one day become a reality.  Read More

Researchers at the University of California claim to have successfully created a roton str...

Helium-4 superfluid is a fascinating substance. With properties that seemingly defy normal physics, it leaks straight through glass, bubbles up out of containers, flows around objects and even climbs up walls. As if superfluid helium-4 was not strange enough, in 1941 it was also predicted that it should contain an exotic, particle-like excitation – a quasiparticle – called a roton. After many years of trying to verify this prediction, researchers at the University of California now claim to have successfully created a roton structure in an atomic superfluid of cesium-133.  Read More

Polymer-based soft robotic grippers can perform biopsies and deliver drugs to previously i...

Creating swarms of soft, robotic hands that can safely dissolve within a living body once they've performed surgical procedures or delivered drugs just got a step closer thanks to work done by John Hopkins University scientists. They've created minute biodegradable microgrippers by adding stiff polymers containing magnetic nanoparticles to soft hydrogels, allowing them be magnetically guided to any location in the body.  Read More

Research team member Dr. Katarzyna Wybranska, with a wound dressing treated with the gold ...

We've been hearing a lot about the antibacterial qualities of silver, with silver nanoparticles finding use in everything from water filters to food packaging. Unfortunately, there are also concerns about the toxicity of those particles, particularly when they enter our bodies. Now, however, Polish scientists have developed what they claim is a safer alternative – an antibacterial coating that kills microbes using gold.  Read More

New algorithms compare a video's background imagery and audio to that of thousands of othe...

Sometimes, a posted video is the only clue to the whereabouts of a missing person, or a terrorist group. Unfortunately, unless that video has already been geo-tagged, it can often be very difficult to tell where it was shot. Now, however, scientists have created algorithms that can determine a video's location by comparing its background imagery and audio to that of thousands of other videos.  Read More
