Science X Newsletter Week 07

Dear Reader ,

Here is your customized Science X Newsletter for week 07:

	Wireless power transmission safely charges devices anywhere within a room A new method developed by Disney Research for wirelessly transmitting power throughout a room enables users to charge electronic devices as seamlessly as they now connect to WiFi hotspots, eliminating the need for electrical cords or charging cradles.
	Dubai aims to launch hover-taxi by July Dubai has tested a Chinese prototype of a self-driving hover-taxi, its transport authority said on Monday, with the aim of introducing the aerial vehicle in the emirate by July.
	Study finds that heel-down posture in great apes and humans confers a fighting advantage Walking on our heels, a feature that separates great apes, including humans, from other primates, confers advantages in fighting, according to a new University of Utah study published today in Biology Open. Although moving from the balls of the feet is important for quickness, standing with heels planted allows more swinging force, according to study lead author and biologist David Carrier, suggesting that aggression may have played a part in shaping our stance.
	Experiments suggest dogs and monkeys have a human-like sense of morality (Phys.org)—A team of researchers from Kyoto University has found that dogs and capuchin monkeys watch how humans interact with one another and react less positively to those that are less willing to help or share. In their paper published in the journal Neuroscience & Biobehavioral Reviews, the team describes a series of experiments they carried out with several dogs and capuchin monkeys and what they discovered about both species social preferences.
	International science collaboration growing at astonishing rate Even those who follow science may be surprised by how quickly international collaboration in scientific studies is growing, according to new research.
	It's more than just climate change A new scientific paper by a University of Maryland-led international team of distinguished scientists, including five members of the National Academies, argues that there are critical two-way feedbacks missing from current climate models that are used to inform environmental, climate, and economic policies. The most important inadequately-modeled variables are inequality, consumption, and population.
	Vitamin D protects against colds and flu, finds major global study Vitamin D supplements protect against acute respiratory infections including colds and flu, according to a study led by Queen Mary University of London (QMUL).
	Food additive found in candy, gum could alter digestive cell structure and function The ability of small intestine cells to absorb nutrients and act as a barrier to pathogens is "significantly decreased" after chronic exposure to nanoparticles of titanium dioxide, a common food additive found in everything from chewing gum to bread, according to research from Binghamton University, State University of New York.
	Biologists find weird cave life that may be 50,000 years old In a Mexican cave system so beautiful and hot that it is called both Fairyland and hell, scientists have discovered life trapped in crystals that could be 50,000 years old.
	New antibiotic from bacteria found on Kenyan ant could help beat MRSA A new antibiotic, produced by bacteria found on a species of African ant, is very potent against antibiotic-resistant 'superbugs' like MRSA according to scientists.
	N. Zealand part of sunken 'lost continent': scientists New Zealand sits atop a previously unknown continent—mostly submerged beneath the South Pacific—that should be recognised with the name Zealandia, scientists said Friday.
	Particles from outer space are wreaking low-grade havoc on personal electronics You may not realize it but alien subatomic particles raining down from outer space are wreaking low-grade havoc on your smartphones, computers and other personal electronic devices.
	Four-stroke engine cycle produces hydrogen from methane and captures CO2 When is an internal combustion engine not an internal combustion engine? When it's been transformed into a modular reforming reactor that could make hydrogen available to power fuel cells wherever there's a natural gas supply available.
	New mechanical metamaterials can block symmetry of motion, findings suggest Engineers and scientists at The University of Texas at Austin and the AMOLF institute in the Netherlands have invented the first mechanical metamaterials that easily transfer motion effortlessly in one direction while blocking it in the other, as described in a paper published on Feb. 13 in Nature. The material can be thought of as a mechanical one-way shield that blocks energy from coming in but easily transmits it going out the other side.
	Optical fibre with Einstein effect Researchers at the Max Planck Institute for the Science of Light in Erlangen have discovered a new mechanism for guiding light in photonic crystal fibre (PCF). PCF is a hair-thin glass fibre with a regular array of hollow channels running along its length. When helically twisted, this spiralling array of hollow channels acts on light rays in an analogous manner to the bending of light rays when they travel through the gravitationally curved space around a star, as described by the general theory of relativity.
	Physicists harness neglected properties of light University of Toronto (U of T) researchers have demonstrated a way to increase the resolution of microscopes and telescopes beyond long-accepted limitations by tapping into previously neglected properties of light. The method allows observers to distinguish very small or distant objects that are so close together they normally meld into a single blur.
	Scientifically-designed fasting diet lowers risks for major diseases What if you could lose weight and reduce your risk of life-threatening disease without any changes in what you eat—other than a five-day special diet once every few months?
	Breakthrough in understanding heat transport with a chain of gold atoms The precise control of electron transport in microelectronics makes complex logic circuits possible that are in daily use in smartphones and laptops. Heat transport is of similar fundamental importance and its control is for instance necessary to efficiently cool the ever smaller chips. An international team including theoretical physicists from Konstanz, Junior Professor Fabian Pauly and Professor Peter Nielaba and their staff, has achieved a real breakthrough in better understanding heat transport at the nanoscale. The team used a system that experimentalists in nanoscience can nowadays realize quite routinely and keeps serving as the "fruit fly" for breakthrough discoveries: a chain of gold atoms. They used it to demonstrate the quantization of the electronic part of the thermal conductance. The study also shows that the Wiedemann-Franz law, a relation from classical physics, remains valid down to the atomic level. The results were published in the scientific journal Science on 16 February 2017.
	Scientists make huge dataset of nearby stars available to public The search for planets beyond our solar system is about to gain some new recruits.
	Ventura fault could cause stronger shaking, new research finds A new study by a team of researchers, including one from the University of California, Riverside, found that the fault under Ventura, Calif., would likely cause stronger shaking during an earthquake and more damage than previously suspected.
