First observation made of quantum-tunneling diffusion of hydrogen atoms on ice
(Phys.org)—As long as the temperature is above absolute zero, gas molecules are always in constant random motion. They may diffuse—or spread out—through three-dimensional space or, in a process called "surface diffusion," along the two-dimensional surface of a solid. The most well-known mechanism to explain surface diffusion is a classical mechanism called thermal hopping, in which gas molecules jump from one adsorption site (the place where the gas molecules attach to the surface) to another at a temperature-dependent rate. So far, thermal hopping is the only mechanism known to explain the surface diffusion of hydrogen atoms on the surface of ice.

Extending a battery's lifetime with heat
Don't go sticking your electronic devices in a toaster oven just yet, but for a longer-lasting battery, you might someday heat them up when not in use. Over time, the electrodes inside a rechargeable battery cell can grow tiny, branch-like filaments called dendrites, causing short circuits that kill the battery or even ignite it in flames. But thanks to new experiments and computer simulations, researchers from the California Institute of Technology have explored in detail how higher temperatures can break down these dendrites—and possibly extend battery lifetimes.

Climate model tagging technique tracks snowpack-melting particles
Airborne soot from fires, burning fossil fuels, and other sources can threaten water supplies in mountainous regions far from the burning source. Now, a new method developed at Pacific Northwest National Laboratory tagged sources of soot from different global regions in a climate model, and tracked where it lands on China's Tibetan Plateau. Researchers determined which areas around the plateau contributed the most soot-and where. The technique also pointed to the most effective way to reduce soot on the plateau to ease the amount of warming the region undergoes.

Chinese team studies airborne microbes across different environments
When people talk about air pollution these days, particulate matter with a diameter smaller than 2.5 microns (PM2.5) immediately comes to mind. Yet, we are often unaware that these tiny particles suspended in the air could be living microbes, such as bacteria, fungal spores, and viruses. Some of these living particles could be human pathogens that can cause serious health outcomes. In addition to health effects, these airborne microbes also have direct impact on cloud formation and climate arising from their special attributes. Virtually any microbes that originated from Earth surfaces—including sea, land, forest, agriculture, animals and humans—could be released into the air and remain airborne for a sustained amount of time.

(Phys.org)—A team of researchers working for pharmaceutical company Merck has found an instance of a molecule that is able to flip a switch in a bacterium that prevents it from synthesizing a needed nutrient, and thus kills it. In their paper published in the journal Nature, the team describes the exhaustive study they undertook to find the molecule and the possibility of it one day being used to treat bacterial infections. Thomas Hermann, of the University of California offers a News & Views piece on the work done by the team in the same journal issue.

Are the blueprints for limbs encoded in the snake genome?
Hundreds of millions of years ago, a common ancestor of mammals, birds, and reptiles evolved a phallus. We don't know much about phallus evolution (external genitalia generally don't mineralize, so the fossil record is of little help), but we can compare the expression of phallus genes from organism to organism. From such work, we've learned that many of the genes deployed in the developing phallus are also used to build limbs during embryonic development.

Sensory feedback shapes individuality to provide equal space for behavioral excellence
We can quickly tell from the way someone walks whether that person is young or old, male or female, healthy or sick, because patterns of movement vary from one person to the next. In fact, we can often recognize a friend from a distance, even if he's walking with his back to us, because of his characteristic strides.

Team aims to revolutionize understanding of how gene variants affect organ transplant outcomes
Nearly 30,000 organ transplants are performed in the United States every year. They routinely extend lives, but the success of these procedures continues to be limited by problems that arise when the recipient's immune system rejects their new organ and other complications. Now, a large international team of transplant surgeons and scientists, co-led by researchers from the Perelman School of Medicine at the University of Pennsylvania, has come together to investigate the genetic factors behind transplant successes and failures. The project, involving more than three dozen research institutions around the world, is called the International Genetics & Translational Research in Transplantation Network (iGeneTRAiN). Their efforts are detailed in a pair of papers published today in Genome Medicine and in the journal Transplantation.

Tissue chips predict neurotoxicity
A lot of time, money, and effort are devoted to developing new drugs. Yet only one of every 10 drug candidates entering human clinical trials successfully goes on to receive approval from the Food and Drug Administration (FDA). Many would-be drugs fall by the wayside because they prove toxic to the brain, liver, kidneys, or other organs—toxicity that, unfortunately, isn't always detected in preclinical studies using mice, rats, or other animal models. That explains why scientists are working so hard to devise technologies that can do a better job of predicting early on which chemical compounds will be safe in humans.

Coincidence or conspiracy? Studies investigate conspiracist thinking
In pop culture, conspiracy believers—like FBI agent Fox Mulder on The X Files or professor Robert Langdon in The Da Vinci Code—tend to reject the notion of coincidence or chance; even the most random-seeming events are thought to result from some sort of intention or design. And researchers have suggested that such a bias against randomness may explain real-world conspiracy beliefs. But new research from psychological scientists at the University of Fribourg and the University of Paris-Saint-Denis shows no evidence for a link between conspiracist thinking and perceptions of order, design, or intent.

Team develops guide on hospital transfers for nursing home residents and their families
Hospitalization of nursing home residents are common and often result in complications and excessive costs. Nearly 1 in 4 people admitted to a skilled nursing facility from acute care are rehospitalized within 30 days at a cost of $14.3 billion annually. It is estimated that as many as two-thirds of those hospitalizations are avoidable. It's been suggested that the role of family members of nursing home residents heavily influences decisions related to transferring residents to the hospital. In order to make optimal decisions concerning hospitalizations, nursing home residents and their families need to have clear information about their treatment options and health conditions.

But it is happening, for cystic fibrosis, Duchenne muscular dystrophy, hemophilia, various inborn errors of metabolism, blindness, and many other conditions. The steps may be incremental for some conditions, but researchers are deploying a staggeringly diverse armamentarium of techniques and technologies to fight genetic disease, from recombinant DNA-based drugs, to enzyme replacement and substrate reduction treatments, to gene therapy, antisense compounds, microRNAs, gene silencing, RNAi, exon skipping, and small molecule approaches.

Study explores ancient ecosystem response to a 'big five' mass extinction
As the planet faces the dawn of a sixth mass extinction, scientists are searching for clues about the uncertain road ahead by exploring how ancient ecosystems collapsed and bounced back from traumatic upheavals. A new study follows the lengthy collapses and revival of South African ecosystems during one of the "big five" mass extinctions, the Permian-Triassic event, revealing unexpected results about the types of animals that were most vulnerable to extinction, and the factors that might best predict community stability during times of great change. The study's authors—including Peter Roopnarine, PhD, of the California Academy of Sciences—say inventive, cutting-edge modeling techniques helped highlight the critical importance of understanding food webs (knowing "who eats what") when trying to predict what communities look like before, during, and after a mass extinction.

Researchers make five recommendations for standardized test designers
Can standardized tests, such as those created in response to the Common Core, enhance education instead of just assessing it? For standardized testing to benefit students, researchers recommend that the tests are used as tools to promote learning, adapt to students' ability levels, provide feedback, and encourage students to make self-assessments and apply memorized information to new situations. This research is out today in the new issue of Policy Insights from the Behavioral and Brain Sciences, a Federation of Associations in Behavioral & Brain Sciences (FABBS) journal published by SAGE.

What happens when you build a pyramid upside down?
On Tuesday, September 29th 2015, Canada achieved a milestone. For the first time in history, the number of people aged 65 and older outnumbered those aged 0 – 14 years of age. A shocking 16% of Canadians – almost one in six – were at least 65 years of age. This is just the start of a bigger trend though, as by 2024, it is predicted that this percentage will grow to 20%, while the share of children will remain stagnant at 16%.

Languages less arbitrary than long assumed
It is a cornerstone of theoretical linguistics: the principle of arbitrariness, according to which the form of a word doesn't tell you anything about its meaning. Yet evidence is accumulating that natural languages do in fact feature several non-arbitrary ways to link form and meaning, and these are more prevalent than assumed. A new review in Trends in Cognitive Sciences presents a comprehensive case for supplementing the cherished principle of arbitrariness with other types of associations between form and meaning.

Why do people vote strategically, and for whom?
Strategic voting is an important factor in Canadian electoral campaigns. "People vote strategically when they think neither their first nor their second choice has any chance of winning in their electorate. They vote for their third choice party in the hopes of blocking an outcome that would be even worse," said Jean-François Daoust, a researcher at the University of Montreal's Department of Political Science who studied the phenomenon as part of his doctoral work. He was directed by André Blais, who holds the university's Research Chair for Electoral Studies, and his findings, which drew on Quebec's 2012 provincial elections, were recently published in Politiques et sociétés.

The long road to more democratic policing
In England and Wales the introduction of directly elected Police and Crime Commissioners (PCCs) in November 2012 was heralded by the government as a great democratising transformation, ensuring that police would be governed through the 'democratic' electoral process rather than the 'bureaucratic' performance management process. Many interested parties, from the Association of Chief Police Officers (ACPO) to civil rights campaign group Liberty, were highly sceptical of PCCs from the start. Many critics of the move took a different view to the government on what makes policing 'democratic', emphasising liberal safeguards such as the 'operational independence' of the police and their subjection to the rule of law.

Investors are indifferent to the technology needs of health-care systems
Health technologies are not governed by the real needs and challenges of healthcare systems, reveals a new University of Montreal study. "Such concerns are absent from public innovation policies and indeed in the way venture capitalists think," said Professor Pascale Lehoux of the university's Department of Health Administration, who led the research. She was motivated by a desire to discover why only some health technologies make their way into healthcare systems and to understand how capital investors choose their investments in new technologies.
