Super-insulated clothing could eliminate need for indoor heating

(Phys.org)—By wearing clothes that have been dip-coated in a silver nanowire (AgNW) solution that is highly radiation-insulating, a person may stay so warm in the winter that they can greatly reduce or even eliminate their need for heating their home. Considering that 47% of global energy is spent on indoor heating, and 42% of that specifically for residential heating, such highly insulating clothing could potentially have huge cost savings.

VERSABALL gripper to play ball and cup game at CES

(Phys.org)—This year’s CES 2015 will draw technology watchers, including industry vendors, buyers and technology media; many in the media will be asked by their publications to keep their focus on booths and events representing the product mainstream—tablets, PCs, phones, smartwatches, automobile apps, connected home devices—avoiding distraction from displays of fun gadgets way out in futureland. We will need some disobedient media watchers, though, because some fun displays will introduce important breakthroughs and practical applications to come.

Nanoscale neighbors: First use of transformation optics to accurately analyze nonlocality in 3D…

(Phys.org) —The ubiquitous van der Waals interaction – a consequence of quantum charge fluctuations – includes intermolecular forces such as attraction and repulsion between atoms, molecules and surfaces. The most long-range force acting between particles, it influences a range of phenomena including surface adhesion, friction and colloid stability.

A repulsive material: New hydrogel properties dominated by electrostatic repulsion

In a world-first achievement, scientists from the RIKEN Center for Emergent Matter Science in Japan, along with colleagues from the National Institute of Material Science and the University of Tokyo, have developed a new hydrogel whose properties are dominated by electrostatic repulsion, rather than attractive interactions.

Best of Last Week – Halting photons, a peer review problem and circadian clock shifting from…

(Phys.org)—It was an interesting week even as we entered the holiday season, researchers at MIT found that halting photons could lead to miniature particle accelerators and perhaps improved data transmission. The light trapping process discovered last year involved twisting the polarization direction now appears to be related to a wide range of other seemingly unrelated phenomena

Finding faster-than-light particles by weighing them

In a new paper accepted by the journal Astroparticle Physics, Robert Ehrlich, a recently retired physicist from George Mason University, claims that the neutrino is very likely a tachyon or faster-than-light particle. There have been many such claims, the last being in 2011 when the “OPERA” experiment measured the speed of neutrinos and claimed they travelled a tiny amount faster than light

A look at North Korea's limited Internet capabilities

An hours-long Internet outage Tuesday in one of the world’s least-wired countries was probably more inconvenient to foreigners than to North Korean residents, most of whom have never gone online. Even for wired Koreans south of the heavily armed border separating the rivals, the temporary outage made little difference—southerners are banned by law from accessing North Korean websites.

New technology directly reprograms skin fibroblasts for a new role

As the main component of connective tissue in the body, fibroblasts are the most common type of cell. Taking advantage of that ready availability, scientists from the Perelman School of Medicine at the University of Pennsylvania, the Wistar Institute, Boston University School of Medicine, and New Jersey Institute of Technology have discovered a way to repurpose fibroblasts into functional melanocytes, the body’s pigment-producing cells.

Anthropologist studies the culture of cattle ranching in the Brazilian Amazon

With more and more rainforest giving way to pasture and grazing land every year, the practice of cattle ranching in the Amazon has serious implications on a global scale. At the same time, however, it provides a degree of socioeconomic flexibility for Amazonian smallholders who simply can’t survive on what the forest or agriculture provide.

Kickstarter Project Hemingwrite offers writers a respite from Internet noise

Entrepreneurs Adam Leeb and Patrick Paul had an idea—a new age typewriter that offered the comforting nostalgia of old fashioned typewriters with the connectability of modern computers, minus the distractions of current devices. They’ve built a prototype, and are calling it the Hemingwrite – a distraction-free digital typewriter
