	World's quietest gas lets physicists hear faint quantum effects Physicists at the University of California, Berkeley, have cooled a gas to the quietest state ever achieved, hoping to detect faint quantum effects lost in the din of colder but noisier fluids.
New device converts DC electric field to terahertz radiation Terahertz radiation, the no-man's land of the electromagnetic spectrum, has long stymied researchers. Optical technologies can finagle light in the shorter-wavelength visible and infrared range, while electromagnetic techniques can manipulate longer-wavelength radiation like microwaves and radio waves. Terahertz radiation, on the other hand, lies in the gap between microwaves and infrared, whether neither traditional way to manipulate waves works effectively. As a result, creating coherent artificial sources of terahertz radiation in order to harness it for human use requires some ingenuity.
	Discovery about how surface gradients influence droplet behavior may enable novel surfaces with anti-icing capabilities Studies of the impact a droplet makes on solid surfaces hark back more than a century. And until now, it was generally believed that a droplet's impact on a solid surface could always be separated into two phases: spreading and retracting.
	The resplendent inflexibility of the rainbow Children often ask simple questions that make you wonder if you really understand your subject. An young acquaintance of mine named Collin wondered why the colors of the rainbow were always in the same order—red, orange, yellow, green, blue, indigo, violet. Why don't they get mixed up?
	Researchers achieve record 3.5 Angstroms resolution and visualize action of major microtubule-regulating protein Microtubules, hollow fibers of tubulin protein only a few nanometers in diameter, form the cytoskeletons of living cells and play a crucial role in cell division (mitosis) through their ability to undergo rapid growth and shrinkage, a property called "dynamic instability." Through a combination of high-resolution cryo-electron microscopy (cryo-EM) and a unique methodology for image analysis, a team of researchers with Berkeley Lab and the University of California (UC) Berkeley has produced an atomic view of microtubules that enabled them to identify the crucial role played by a family of end-binding (EB) proteins in regulating microtubule dynamic instability.
	Researchers clear the way for fast plasmonic chips Researchers from the Laboratory of Nanooptics and Plasmonics at the MIPT Center of Nanoscale Optoelectronics have developed a new method for optical communication on a chip, which will could decrease the size of optical and optoelectronic elements and greatly increase computer performance. According to an article published in Optics Express, they have proposed a way to completely eliminate energy loss of surface plasmons in optical devices.

Earth news

	End-of-century Manhattan climate index to resemble Oklahoma City today Climate change caused by greenhouse gas emissions will alter the way that Americans heat and cool their homes. By the end of this century, the number of days each year that heating and air conditioning are used will decrease in the Northern states, as winters get warmer, and increase in Southern states, as summers get hotter, according to a new study from a high school student, Yana Petri, working with Carnegie's Ken Caldeira. It is published by Scientific Reports.
	Researchers suggest office thermostat settings biased against women (Phys.org)—A pair of researchers with the Maastricht University Medical Center in The Netherlands has conducted a study into the comfort level of office buildings for women. In their paper published in the journal Nature Climate Change, Boris Kingma and Wouter van Marken Lichtenbelt, report that they have found that many office thermostat settings are based on an outdated formula that leaves women feeling cold in their work environment. Joost van Hoof with Fontys University discusses the study by the two in a News & Views piece in the same journal issue and concludes that formulas used to set office workspace temperatures need to be updated to include the needs of not just women, but people of different weights and ages.
	Can't we just remove carbon dioxide from the air to fix climate change? Not yet If we have put too much CO2 into the air, wouldn't it make sense to find ways to remove it again? Well, yes: it would. But sadly it isn't likely to be easy or cheap and, according to new research, it isn't an adequate "solution" to the problems of climate change.
	Global index proposed to avoid delays on climate policies Professor David Frame, Director of Victoria's Climate Change Research Institute (CCRI), has co-authored a paper published today in the high profile international scientific journal Nature Climate Change. The paper argues that the 'pledge and review' approach that will form the basis of commitments made at the United Nations climate change negotiations in December, presents an opportunity to explicitly link mitigation goals to the evolving climate response.
	Computer simulation shows climate mitigation schemes could result in increased water stress (Phys.org)—A combined team of researchers from Pacific Northwest National Laboratory and the University of Maryland has created a computer simulation meant to show the degree of water stress in the U.S. going forward into the future—it shows that under some conditions, water stress may actually increase due to mitigation efforts designed to slow global warming. In their paper published in Proceedings of the National Academy of Sciences, the team describes their simulation and why they believe it shows the dangers of not clearly thinking through strategies meant to help reduce greenhouse gas emissions.
Researchers use wastewater treatment to capture CO2, produce energy Cleaning up municipal and industrial wastewater can be dirty business, but engineers at the University of Colorado Boulder have developed an innovative wastewater treatment process that not only mitigates carbon dioxide (CO2) emissions, but actively captures greenhouse gases as well.
	Conservationist cautions against greenhouse gasses from conferences Academic conferences are resulting in significant greenhouse gas emissions and conservationists are not immune. But all hope is not lost, according to FIU researchers.
Protecting the environment by re-thinking death Scientists first had to re-think death before they could develop a way of testing the potential harm to the environment caused by thousands of chemicals humankind uses each day.
	Precariously balanced rocks suggest San Jacinto, San Andreas may have ruptured together Stacked in gravity-defying arrangements in the western San Bernardino Mountains, granite boulders that should have been toppled long ago by earthquakes are maintaining a stubborn if precarious balance. In puzzling out why these rocks still stand, researchers have uncovered connections between Southern California's San Jacinto and San Andreas faults that could change how the region plans for future earthquakes.
	Russia files UN claim over vast swathe of Arctic Russia pressed a claim at the United Nations Tuesday for an additional 1.2 million square kilometres (463,000 square miles) of Arctic shelf, stepping up a race for the region's hydrocarbon and mineral wealth.
	Food for thought! Technology can reduce domestic food waste Consumers waste food because they don't know what's in their fridge, where it's located or how best to use it, a new QUT study has revealed.
	North Korea to fight food insecurity and natural disaster with trees Experts in DPR Korea intend to restore the quality of forest lands, alleviate wide-spread food insecurity and reduce the frequency of natural disasters in the country through an ambitious programme of agroforestry "the use of trees on farms and in the landscape". The DPR Korea is only the second country in Asia to launch such an initiative.
	Qualified praise for Obama's clean power plan President Barack Obama's plan to slash electricity-generated CO2 emissions was welcomed Tuesday as a courageous step towards a lower-carbon future, but not yet enough to brake dangerous planet warming.

Astronomy & Space news

	Neutron stars strike back at black holes in jet contest Some neutron stars may rival black holes in their ability to accelerate powerful jets of material to nearly the speed of light, astronomers using the Karl G. Jansky Very Large Array (VLA) have discovered.
	Tracking a mysterious group of asteroid outcasts High above the plane of our solar system, near the asteroid-rich abyss between Mars and Jupiter, scientists have found a unique family of space rocks. These interplanetary oddballs are the Euphrosyne (pronounced you-FROH-seh-nee) asteroids, and by any measure they have been distant, dark and mysterious—until now.
	5 billion light years across—the largest feature in the universe A Hungarian-US team of astronomers have found what appears to be the largest feature in the observable universe: a ring of nine gamma ray bursts – and hence galaxies - 5 billion light years across. The scientists, led by Prof Lajos Balazs of Konkoly Observatory in Budapest, report their work in a paper in Monthly Notices of the Royal Astronomical Society.
	Will SETI's unprecedented new program finally find E.T.? Stephen Hawking, Frank Drake and dozens of journalists gathered at the Royal Society in London last week to hear astronomers announce a ground-breaking new project to search for intelligent extraterrestrial life called "Breakthrough Listen." They will be using two of the world's largest radio telescopes (Green Bank Telescope in West Virginia and the Parkes Radio Telescope in Australia) to listen for radio messages from intelligent alien species. Scientists have chosen to target the nearest million stars as well as the nearest 100 galaxies. This project will also monitor the Galactic plane for months at a time. This unprecedented effort is a collaboration between UC Berkeley and the Breakthrough Prize Foundation, and employs an international team of astronomers and data scientists, including Frank Drake – the father of SETI (Search for ExtraTerrestrial Intelligence).
	The ghostly remnants of galaxy interactions uncovered in a nearby galaxy group Astronomers using the Subaru Telescope's Hyper Suprime-Cam prime-focus camera recently observed the nearby large spiral galaxy M81, together with its two brightest neighbors, M82 and NGC3077. The results of their observations are deep, super wide-field images of the galaxies and their populations of young stars. As part of a Galactic Archaeology study, the team discovered that the spatial distribution of the young stars around these galaxies follows very closely that of their distribution of neutral hydrogen.
	Small prototype Earth return capsule flight tested A prototype capsule that one day will return science experiments to Earth was tested by releasing it from a high-altitude balloon in Tillamook, Oregon. Technology like this capsule could one day return biological samples and other small payloads from space in a relatively short time.
	Video: Atlantis Chaos flyover This colourful image is a topography map of a portion of the region known as Terra Sirenum, located in the southern hemisphere of Mars. The map is colour-coded, with reds and whites representing the highest topography and blues and purples the lowest.

Technology news

	Thunderstrike 2: Proof-of-concept worm could infect Macs Two researchers, Xeno Kovah co-founder of LegbaCore and Trammell Hudson, a security engineer with Two Sigma Investments, have created a proof of concept worm capable of attacking Mac computers. The worm which they designed can spread from MacBook to MacBook without them even being networked. If one were to actually be a victim of this kind of attack, a solution would be nothing less than opening up the machine and electrically reprogramming the chip. For many users, that solution would be daunting. They might take the easier way out, which is to slip the machine into a gym bag and put it in the back of the closet, on top of the pile of broken exercise equipment and ironing board.
	Engineers use the environment to give simple robotic grippers more dexterity Most robots on a factory floor are fairly ham-handed: Equipped with large pincers or claws, they are designed to perform simple maneuvers, such as grabbing an object, and placing it somewhere else in an assembly line. More complex movements, such as adjusting the grasp on an object, are still out of reach for many industrial robots.

	Your mobile phone knows where you go and what you do – and maybe even when you're feeling down Today's smartphones are equipped with powerful sensing capabilities. Using these sensors, your smartphone potentially has a record of how active you are, how much you sleep and where you go. If we look at the data those sensors gather, we can get a pretty good idea of what someone's typical behavior is like.
	Offshore wind farms, hurricanes, and sustainability Block Island, which is located 13 miles off the Rhode Island coast, will soon be home to North America's first offshore wind farm. Late last month, Deepwater Wind, the company behind the $338 million project, installed the first of five steel foundations to the ocean floor—one for each wind turbine. The five turbines—which will be working by fall 2016—will be expected to produce enough energy to power 17,000 homes and cut the island's energy bills by 40 percent.
	Windows 10 is not really free—you are paying for it with your privacy Windows 10, it seems, is proving a hit with both the public and the technology press after its release last week. After two days, it had been installed on 67 million PCs. Of course, sceptics may argue that this may have simply been a reflection of how much people disliked Windows 8 and the fact that the upgrade was free.
	We're only just starting to understand the side-effects of driverless cars The dawn of driverless cars is almost upon us. Governments around the world are rapidly legalising the use of driverless vehicles on their roads and are working towards overcoming regulatory difficulties associated with their large-scale introduction. Meanwhile, some of the largest technology and automotive corporations in the world are investing heavily in driverless technologies. Many people in industry seem certain that the largest revolution in personal transport since the invention of the car itself is less than a decade away.

Perhaps with a sufficient number of experts, each bringing a little knowledge of the ocean, currents, wreck salvage, and so forth, the lost aircraft could be found by pooling all this expertise.
	The autonomous killing systems of the future are already here, they're just not necessarily weapons – yet When the discussion of "autonomous weapons systems" inevitably prompts comparisons to Terminator-esque killer robots it's perhaps little surprise that a number of significant academics, technologists, and entrepreneurs including Stephen Hawking, Noam Chomsky, Elon Musk, Demis Hassabis of Google and Apple's Steve Wozniak signed a letter calling for a ban on such systems.
	Science still at heart of solving MH370 mystery The discovery of a Boeing 777 flaperon on Reunion Island has vaulted Malaysian Airlines flight 370's disappearance into world headlines again, but is intensive media interest bringing us closer to the truth?
	Multi-platform media and the digital challenge – an analysis The UK media sector's rapid expansion onto new, multiple digital platforms in the face of tighter financial budgets has encouraged more emphasis on strongly branded and high impact content, according to University of Glasgow research which was funded by the Economic and Social Research Council (ESRC).
	Process concept for a zero-emission route to clean middle-distillate fuels from coal A novel process configuration has been developed for producing clean middle-distillate fuels from coal with minimal emissions. The EMS Energy Institute at Penn State University has developed and tested a solvent extraction process for making liquids from bituminous coals, and has shown the successful use of these fuels in small jet engines, a diesel-engine pickup truck, and a solid oxide fuel cell. The core of the process involves extracting coals with light cycle oil, a refinery byproduct, separating the residual solids, hydrotreating the liquid to remove sulfur, hydrogenating to eliminate aromatic compounds, and finally distilling to obtain the fuel products, which represent the majority of the liquid yield. The optimum yield of the raw extract, after three stages of extraction, is as high as 75%. The recovery of middle-distillate fuels from the hydrotreated and hydrogenated extract is up to 80%. A solvent stream would be recycl! ed back to the front end of the process.

	Beauty and the beast can benefit Scottish salmon industry It's ugly; it's clingy, yet University of Stirling Aquaculture experts are focusing on the Lumpsucker - an unlikely hero in the bid to boost the salmon industry.
	A web-based application for biorefinery design and evaluation of serial biomass fermentation The composition of feedstock biomass and the selection of fermenting microorganisms are critical factors in biorefinery design. Once biomass feedstock is identified, depending on local conditions, biorefinery designers need to select optimal fermenting organisms. Using organism communities has theoretical advantages but also leads to problems in the context of species competition, process design and modelling, in turn resulting in insufficient process control.
	The consortium of motile and cellulose degrading bacteria can be used for solid state cellulose hydrolysis Cellulose hydrolysis has many industrial applications in such fields as biofuel production, food, paper, cosmetic, pharmaceutical industries and textile manufacture.

	Riding a horse is far more complex than riding simulators Flight simulators for the training of air pilots are well known. But what about riding simulators? Although the first horse simulator was used at the French National Equestrian School in Saumur already in the 1980s, riding simulators for dressage, show jumping, polo or racing, have become available only recently. They look like horses and respond to the aids of the rider via sensors which measure the force exerted by the reins and the rider's legs. Via a screen in front of the simulator, the rider immerses himself into a virtual equestrian world.
	Study explains the unique sound production by Death's head hawkmoths Their arrival used to be perceived as a bad omen: Because of their scull-like markings on their backs the Death's head hawkmoths (Acherontia atropos) were dreaded. And yet, the big moth with the dark forewings and the beige-yellow marking is unusual for more than one reason: The animals migrate annually from Africa to Europe and visit beehives from which they steal honey with their short proboscides. If the moths are irritated, they produce series of short squeaks. Scientists from the Universities Jena and Kiel, the Ernst-Abbe-Hochschule Jena and the University Hospital Jena (all Germany) looked into their unique way of producing sounds. The results of the joint research have now been published in the science magazine The Science of Nature.

From pluripotency to totipotency While it is already possible to obtain in vitro pluripotent cells (ie, cells capable of generating all tissues of an embryo) from any cell type, researchers from Maria-Elena Torres-Padilla's team have pushed the limits of science even further. They managed to obtain totipotent cells with the same characteristics as those of the earliest embryonic stages and with even more interesting properties. Obtained in collaboration with Juanma Vaquerizas from the Max Planck Institute for Molecular Biomedicine (Münster, Germany), these results are published on 3rd of August in the journal Nature Structural & Molecular Biology.
	Seagrass thrives surprisingly well in toxic sediments—but still dies all over the world Toxic is bad. Or is it? New studies of seagrasses reveal that they are surprisingly good at detoxifying themselves when growing in toxic seabed. But if seagrasses are stressed by their environment, they lose the ability and die. All over the world seagrasses are increasingly stressed and one factor contributing to this can be lack of detoxification.

Regenerating damaged cardiac muscle To mend a broken heart—that is, to regenerate a damaged cardiac muscle—it helps to know how hearts are built. "How does one stem cell, which has no specific identity, develop into multiple cell types that organize into this beautiful three-dimensional structure?" asks Laurie Boyer, associate professor in the MIT Department of Biology, who tackles that problem by investigating regulatory elements that switch genes on and off at the right time and place during development. Faulty regulation can lead to congenital heart defects, which are the greatest cause of infant morbidity and mortality.

Modelling the effect of vaccines on cholera transmission Cholera is a diarrhoeal disease that is caused by an intestinal bacterium, Vibrio cholerae. Recently an outbreak of cholera in Haiti brought public attention to this deadly disease. In this work, the goal of our differential equation model is to find an effective optimal vaccination strategy to minimize the disease related mortality and to reduce the associated costs. The effect of seasonality in pathogen transmission on vaccination strategies was investigated under several types of disease scenarios, including an endemic case and a new outbreak case. This model is an extension of a general water-borne pathogen model. This work involves the optimal control problem formulation, analysis and numerical simulations.

The predictions of this simulation, reported by Andrew Moran of Columbia University and colleagues, indicate that such a program should also be borderline cost-effective, provided low cost essential anti-hypertensive drugs are used.
Key protein drives 'power plants' that fuel cells in heart and other key body systems Case Western Reserve University scientists have discovered that a protein called Kruppel-like Factor 4 (KLF4) controls mitochondria—the "power plants" in cells that catalyze energy production. Specifically, they determined KLF4's pivotal role through its absence—that is, the mitochondria malfunction without enough of the protein, which in turn leads to reduced energy. This decline is particularly problematic in the heart because lower energy can lead to heart failure and death.
	Team advances therapy preventing addiction relapse by erasing drug-associated memories Recovering addicts often grapple with the ghosts of their addiction—memories that tempt them to relapse even after rehabilitation and months, or even years, of drug-free living. Now, scientists from the Florida campus of The Scripps Research Institute (TSRI) have made a discovery that brings them closer to a new therapy based on selectively erasing these dangerous and tenacious drug-associated memories.
