Nanotechnology news

	Researchers calculate electrical properties of carbon cones, other shapes Flexing graphene may be the most basic way to control its electrical properties, according to calculations by theoretical physicists at Rice University and in Russia.
	Team maps distribution of carbon nanotubes in composite materials Despite their small size and simple structure, carbon nanotubes—essentially sheets of graphene rolled up into straws—have all sorts of potentially useful properties. Still, while their promise looms large, how to fully realize that promise has proven to be something of a mystery.
	Atomic force microscope advance leads to new breast cancer research Researchers who developed a high-speed form of atomic force microscopy have shown how to image the physical properties of live breast cancer cells, for the first time revealing details about how deactivation of a key protein may lead to metastasis.
	Researchers develop new biodegradable silicon transistor based on a material derived from wood Portable electronics users tend to upgrade their devices frequently as new technologies offering more functionality and more convenience become available. A report published by the U.S. Environmental Protection Agency in 2012 showed that about 152 million mobile devices are discarded every year, of which only 10 percent is recycled—a legacy of waste that consumes a tremendous amount of natural resources and produces a lot of trash made from expensive and non-biodegradable materials like highly purified silicon.
	Chitosan coated, chemotherapy packed nanoparticles may target cancer stem cells Nanoparticles packed with a clinically used chemotherapy drug and coated with an oligosaccharide derived from the carapace of crustaceans might effectively target and kill cancer stem-like cells, according to a recent study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James).
	Pomegranate-like nanocomposites: The new avenue of graphene in water splitting The looming fossil energy crisis and serious environment and climate issues urgently call for sustainable energy systems and next-generation energy storage technologies. Instead of a traditional "carbon cycle" based on fossil energy, the "hydrogen cycle" has emerged and may be a promising alternative. With a water splitting device, H2 can be generated from water by electricity or solar energy, and energy transforms between electrical/solar and chemical energy in rechargeable batteries. However, the core issue of water splitting, oxygen evolution reaction (OER) (4OH- —> 2H2O + O2 + 4e-, in base), is a kinetically sluggish half-reaction, which requires a high overpotential and hinders the development of water splitting.

Physics news

	New method of quantum entanglement vastly increases how much information can be carried in a photon A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart they are —a phenomenon known as quantum entanglement.
	New model of cosmic stickiness favors 'Big Rip' demise of universe The universe can be a very sticky place, but just how sticky is a matter of debate.
	How biological motors and molecules can be used to measure magnetic materials Ludwig Maximilian University physicists were able to show how biological motors and molecules can be used to carry out precise measurements of magnetic materials.
	Samsung develops lithium-ion battery with nearly double the life (Phys.org)—A team of researches affiliated with Samsung's Advanced Institute of Technology, along with colleagues from other institutions in Korea has found a way to greatly extend lithium-ion battery life. In their paper published in the journal Nature Communications, the team describes their new technique and the results they achieved using it.
	Using muons from cosmic rays to find fraying infrastructure In the United States, electricity comes with the flip of a switch and heat arrives with the push of a button. Behind such convenience lies a massive infrastructure network that produces and distributes energy. And just like roads wear down and need to be repaved occasionally, this energy infrastructure degrades over time. Pipes can corrode and concrete can wear thin. Failure can be catastrophic: when a Manhattan steam pipe burst in 2007, the resulting explosion killed one person, injured 30, and caused an estimated $30 million in damage to nearby businesses.
	Study of storage material magnesium hydride may give boost to hydrogen cars The dream of a cleaner, greener transportation future burns brightly in the promise of hydrogen-fueled, internal combustion engine automobiles. Modern-day versions of such vehicles run hot, finish clean and produce only pure water as a combustion byproduct.
	Highly-precise comparison of mercury and strontium optical lattice clocks A University of Tokyo and RIKEN research group has developed a mercury-based optical lattice clock and measured the mercury clock frequency using the same group's recently developed strontium-based optical lattice clock as a reference. The research group achieved a fractional frequency uncertainty, which is smaller than the realization of the current international standard definition of the second.
	We've just started work on the technology to power a Star-Trek style replicator Who has never dreamt of having a machine that can materialise any object we need out of thin air at the push of a button? Such machines only exist in the minds of science fiction enthusiasts and the film industry. The most obvious example is the "replicator" that Star Trek characters routinely use to generate a diverse range of objects, helping them escape from even the most impossible of plotlines.
Report: Careers outside of academia are richly rewarding for Ph.D. physicists When asked to picture someone with a PhD in physics, most people probably envision an academic in a lab—and not, say, a CEO or a financial analyst. In reality, though, physicists aren't limiting themselves to the ivory tower. Out of necessity or choice, many leave academia for jobs in the private sector, pursuing careers that are traditionally not tracked in workforce surveys of the physics field.
	How magnetism manifests in the universe I have a confession: I'm obsessed with magnets.

Earth news

	Study shows Lake Mega-Chad dried up far more quickly than thought (Phys.org)—A trio of researchers from the University of London and King's College, studying the history of Lake Chad has found that the lake was reduced to its current size very quickly just 1,000 years ago.

	Algorithm accounts for uncertainty to enable more accurate modeling A notable error source in modeling physical systems is parametric uncertainty, where the values of model parameters that characterize the system are not known exactly due to limited data or incomplete knowledge. In this situation, a data assimilation algorithm can improve modeling accuracy by quantifying and reducing such uncertainty. However, these algorithms often require a large number of repetitive model evaluations that incur significant computational resource costs. In response to this issue, PNNL's Dr. Weixuan Li and Professor Guang Lin from Purdue University have proposed an adaptive importance sampling algorithm that alleviates the burden caused by computationally demanding models. In three test cases, they demonstrated that the algorithm can effectively capture the complex posterior parametric uncertainties for the specific problems being examined while also enhancing computational efficiency.

Chemistry news

	Substrates change nanoparticle reactivity (Phys.org)—Nanoscale materials tend to behave differently than their bulk counterparts. While there are many theories as to why this happens, technological advances in scanning tunneling microscopy (STM) have allowed researchers to investigate many of these causes by looking at the properties of a single nanoparticle. One area that requires further investigation is how substrate topology affects nanoparticle reactivity. Using the well-known interaction between carbon monoxide (CO) and substrate-supported palladium (Pd) nanoparticles, researchers from the London Centre for Nanotechnology and University College London have demonstrated, for the first time, that the topology of the titanium dioxide (TiO2) substrate affects Pd nanoparticle reactivity. Their findings are reported in the Proceedings of the National Academy of Sciences.
	Fuel cell designers need to look beyond the catalyst to the support material Quickly, reliably turning wind energy into fuel means looking beyond the catalyst to its foundation, according to a recent study from the Center for Molecular Electrocatalysis, headquartered at Pacific Northwest National Laboratory. Led by Dr. James Mayer from Yale University, the team discovered that the foundation or supporting film has as substantial an impact as the catalyst structure itself. The reason? The technique used to place the support changes the mesoscale environment, the atomic landscape that stretches for several millimeters around the iron catalyst.
	Actuators that mimic ice plants Engineers developing moveable robot components may soon take advantage of a trick plants use. Researchers at the Max Planck Institute of Colloids and Interfaces in Potsdam and Harvard University in Cambridge (USA) have devised porous materials that could serve as actuators, or motors. The dynamic mechanism of the material resembles that of some plant tissues. When pressure is increased in the pores of the polymer, the structure swells and expands in a preferred direction. In this way, the researchers mimic the mechanism by which some non-vital parts of plants perform movements, e.g. the seed capsules of ice plants. The researchers used theoretical modelling to analyse how the expansion behaviour of the materials depends on its structure and tested the results with advanced 3D printing technology. The new findings could serve as a basis for designing moveable components with especially natural mobile properties, for example for applications in robots.
Research could help point the finger at drug dealers An innovative technology pioneered by Sheffield Hallam University academics can detect the presence of a range of illegal and designer drugs from a single fingerprint, which could be a valuable new tool in bringing drug dealers and other criminals to justice.
	Chemists characterize 3-D macroporous hydrogels Carnegie Mellon University chemists have developed two novel methods to characterize 3-dimensional macroporous hydrogels—materials that hold great promise for developing "smart" responsive materials that can be used for catalysts, chemical detectors, tissue engineering scaffolds and absorbents for carbon capture.
	New concrete composite can heal itself In the human body, small wounds are easily treated by the body itself, requiring no further care. For bigger wounds to be healed, the body may need outside assistance. Concrete is like a living body, in that it can self-heal its own small wounds (cracks) as an intrinsic characteristic. However, cracks do not heal easily in conventional concrete due to its rather brittle nature, which calls into question the effectiveness of self-healing in conventional concrete materials with no control over crack formation.
	Reviving cottonseed meals adhesives potential Cottonseed meal—the leftovers after lint and oil are extracted from cottonseed—is typically fed to ruminant livestock, such as cows, or used as fertilizer. But Agricultural Research Service scientists in New Orleans, Louisiana, have other plans for this byproduct of U.S. cotton production—namely, to make interior wood adhesives.

Mountain near Vegas gains blue butterfly habitat protection A scarce and endangered butterfly found only on Mount Charleston near Las Vegas is getting a kind of habitat insurance policy, under an agreement announced Monday by the federal government and a conservation group.
	Europeans have unknowingly contributed to the spread of invasive plant species in the US Halle (Saale). The role of plant traits might be overestimated by biologists in studies on plant invasiveness. Anthropogenic factors such as whether the spcies was being cultivated proved to be more important. These conclusions were made from a study on Central European plants that were introduced by humans to North America and over time became naturalised in this continent. Naturalisation of new plant species, a process that makes it a permanent member of the local flora, most strongly depends on residence time in the invaded range and the number of habitats occupied by species in their native range, researchers reported in the journal Ecology.

	Men and women could use different cells to process pain We have known for some time that there are sex differences when it comes to experiencing pain, with women showing a higher sensitivity to painful events compared to men. While we don't really understand why this is, it seems likely that both biological and psycho-social factors are involved. However, a new study published in Nature Neuroscience suggests that there may be a sex difference in the immune cells involved in the processing of pain signals. The results show that it is time to stop ignoring sex differences in research.
	Small RNAs found to play important roles in memory formation Scientists from the Florida campus of The Scripps Research Institute (TSRI) have found that a type of genetic material called "microRNA" plays surprisingly different roles in the formation of memory in animal models. In some cases, these RNAs increase memory, while others decrease it.
	Majority of men who use violence toward partners struggle with serious mental health issues The majority of men who use violence towards their partner struggle with serious mental health issues. We need to look at more than just the power relations between the sexes in order to understand and prevent domestic violence, says researcher.
	Molecular switch for a healthy metabolism discovered The protein complex mTORC1 is a central regulator of cell metabolism. In the active state, it stimulates anabolic processes and increases the production and storage of proteins and lipids. Researchers from the German Leibniz Institute for Age Research in Jena and the Dutch Ageing Institute ERIBA in Groningen discovered how mTORC1 regulates metabolism: It controls the expression of a specific variant of the transcriptional regulator C/EBPβ. Elimination of this variant in mice results in a healthy metabolism, leanness and improved insulin sensitivity. The study may provide a basis for novel strategies for the treatment of metabolic diseases such as obesity and type II diabetes.
Reassurance can be as important as waiting times for ambulance patients Ambulance services should be assessed on how reassured patients and their families feel during an emergency as well as on response times, researchers have found.

	Particulate matter from modern gasoline engines damages our lungs Particulate matter from gasoline engines is harmful to our airways, regardless of whether the engines are a bit older or comply with recent EU standards. Fine dust particles allow pathogens to enter the lungs easier. Researchers at the University of Bern and the Paul Scherrer Institute PSI have shown this conducting a realistic laboratory experiment.
	Why are some children more giving than others? Parents and educators are acutely aware that children can be both excessively self-oriented and overwhelmingly generous. For every preschooler refusing to share his toy truck, there's an 8-year-old who insists on giving all of his allowance money to the homeless. Kids can also enjoy their altruism. One study found that even two-year-olds were happier giving something away than receiving a gift.
	New genetic form of obesity and diabetes discovered Scientists have discovered a new inherited form of obesity and type 2 diabetes in humans.
Efficacy of topical benzoyl peroxide on the reduction of propionibacterium acnes during shoulder surgery A new paper to be published in The Journal of Shoulder and Elbow Surgery evaluates the effect that topical benzoyl peroxide (BPO), with chlorhexidine skin preparation, has on the presence of Propionibacterium acnes cultured at the time of shoulder surgery. The authors hypothesized that adding topical BPO, the active ingredient in Clearasil, to the pre-operative skin preparation would reduce the number of positive P. acnes cultures identified during surgery.

	Hello, gorgeous! 'Pulse' technology may replenish skin's collagen Americans spend over $10 billion a year on products and surgery in their quest to find a "fountain of youth," with little permanent success. Botulinum toxin—notably Botox—which smoothes lines and wrinkles to rejuvenate the aging face has been the number one nonsurgical procedure in the U.S. since 2000. But injections of this toxic bacterium are only a temporary solution and carry many risks, some neurological.

Report urges major steps to help victims of cardiac arrest Would you know what to do if you see someone collapse, not breathing—a loved one at home, a co-worker at the office, a stranger on the street? Far too many Americans die of cardiac arrest, and now a major new report urges a national campaign to improve survival in part by making sure more bystanders know how to help.
Cardiac survival rates around six percent for those occurring outside of a hospital Cardiac arrest strikes almost 600,000 people each year, killing the vast majority of those individuals, says a new report from the Institute of Medicine. Every year in the U.S., approximately 395,000 cases of cardiac arrest occur outside of a hospital setting, in which less than 6 percent survive. Approximately 200,000 cardiac arrests occur each year in hospitals, and 24 percent of those patients survive. Estimates suggest that cardiac arrest is the third leading cause of death in the U.S. behind cancer and heart disease.
Sialic acid: A key to unlocking brain disorders A new report published in the July 2015 issue of The FASEB Journal suggests that a common molecule found in higher animals, including humans, affects brain structure. This molecule may play a significant role in how brain cells communicate, possibly shedding light on the underlying causes of certain brain disorders. The study, involving mice, shows that small changes in how sialic acid attaches to cell surfaces result in damaging effects on brain structure, poor motor skills, hyperactivity, and difficulty in learning.
	Vitamin A supplementation may cause the immune system to 'forget' past infections Although vitamin A supplementation can have profound health benefits when someone is deficient, new evidence is emerging to show that vitamin A supplementation above and beyond normal levels may have negative health consequences. A new research report published in the July 2015 issue of the Journal of Leukocyte Biology may help to explain why too much vitamin A can be harmful. Too much vitamin A shuts down the body's trained immunity, opening the door to infections to which we would otherwise be immune. This study adds to the arguments that vitamin A supplementation should only be done with clear biological and clinical arguments. Furthermore, it also suggests that low vitamin A concentrations in certain situations may even be "normal."
	Omega-3 supplements and antioxidants may help with preclinical Alzheimer's disease Here's more evidence that fish oil supplementation and antioxidants might be beneficial for at least some people facing Alzheimer's disease: A new report published in the July 2015 issue of The FASEB Journal describes the findings of a very small study in which people with mild clinical impairment, such as those in the very early stages of the disease, saw clearance of the hallmark amyloid-beta protein and reduced inflammation in neurological tissues. Although the findings involved just 12 patients over the course of 4 to 17 months, the findings suggest further clinical study of this relatively inexpensive and plentiful supplement should be conducted.
Osteopathic manipulative therapy significantly improves low back pain in postpartum women German researchers found osteopathic manipulative therapy (OMTh) decreased postpartum low back pain by over 70 percent in women who had given birth at least three months before beginning treatment, according to a new study published in July issue of the Journal of the American Osteopathic Association.
	Review of vegetarian diet studies highlights benefit of vegan-eating plans People on a vegetarian diet, and especially those following a vegan one that includes no animal products, see better results than dieters on other weight-reducing plans. In fact, they can lose around two kilograms more on the short term, says Ru-Yi Huang of E-Da Hospital in Taiwan after reviewing the results of twelve diet trials. The findings appear in the Journal of General Internal Medicine.
Bisexual men and women report poorer health than gays, lesbians and heterosexuals Bisexual males and females report poorer health than gays, lesbians and heterosexuals, according to a new study from sociologists at Rice University.
Cheek muscles hold up better than leg muscles in space It is well known that muscles need resistance (gravity) to maintain optimal health, and when they do not have this resistance, they deteriorate. A new report published in the July 2015 issue of The FASEB Journal, however, suggests that this might not be true for all muscles, offering hope that there may be ways to preserve muscle mass and strength for individuals in low-resistance environments, whether it be the microgravity of space, extended periods in a hospital bed, or a 9-5 job behind a desk.
	For women with bipolar disorder, sleep quality affects mood Poor sleep is associated with negative mood in women with bipolar disorder, according to researchers at Penn State College of Medicine and University of Michigan Medical School.
	Women's faces get redder at ovulation, but human eyes can't pick up on it Previous studies have shown that men find female faces more attractive when the women are ovulating, but the visual clues that allow this are unclear. Now, new research investigating whether it might be to do with subtle changes in skin colour has shown that women's faces do increase in redness during ovulation, but the levels of change are just under the detectable range of the human eye.
Innovative imaging study shows that the spinal cord learns on its own The spinal cord engages in its own learning of motor tasks independent of the brain, according to an innovative imaging study publishing on June 30th in Open Access journal PLOS Biology.

The implications of medical tourism for patients and health systems Patients who travel abroad for medical treatment risk returning with complications or infections that require costly treatment on the NHS and is one of the issues highlighted in a new handbook exploring medical tourism.
Vision screening in preschool-aged children: Benefit and harm still unclear It remains unclear whether a special ophthalmological examination of all children younger than 6 years (and potential follow-up treatments) would reduce the frequency and severity of visual impairment (amblyopia) in the population. An update search conducted for a benefit assessment of the German Institute for Quality and Efficiency in Health Care (IQWiG) from 2008 identified no new screening study. No benefit of vision screening in preschool-aged children could be derived from the only new treatment study. This is the finding of a rapid report prepared by IQWiG on behalf of the Federal Joint Committee (G-BA) and published on 17 June 2015.
Spouses and relatives of celiac disease patients at risk for autoimmune diseases Both spouses and first-degree relatives of patients with celiac disease are at increased risk of nonceliac autoimmune disease, according to a study in the July issue of Clinical Gastroenterology and Hepatology, the official clinical practice journal of the American Gastroenterological Association. This risk represents a mixture of genetic, environmental and ascertainment bias mechanisms.
