| Check less to reduce email stress Posted: 03 Dec 2014 11:26 AM PST Is your inbox burning you out? Then take heart -- research suggests that easing up on email checking can help reduce psychological stress. Some of the study's 124 adults -- including students, financial analysts medical professionals and others -- were instructed to limit checking email to three times daily for a week. Others were told to check email as often as they could (which turned out to be about the same number of times that they normally checked their email prior to the study).  |
| Brain network detected that gives humans superior reasoning skills Posted: 03 Dec 2014 11:26 AM PST When it comes to getting out of a tricky situation, we humans have an evolutionary edge over other primates. Scientists have found mounting brain evidence that helps explain how humans have excelled at 'relational reasoning,' a cognitive skill in which we discern patterns and relationships to make sense of seemingly unrelated information.  |
| Protect the world's deltas, experts urge Posted: 03 Dec 2014 11:26 AM PST Extensive areas of the world's deltas -- which accommodate some of the world's major cities -- will be drowned in the next century by rising sea levels, according to new work. A geologist calls for maintenance efforts to be started now to avert the loss of vast expanses of coastline, and the consequent losses of ecological services, economic and social crises, and large-scale migrations.  |
| Atomic-level view provides new insight into translation of touch into nerve signals Posted: 03 Dec 2014 11:25 AM PST The sensation of touch starts as mechanical force that is transformed into an electrical signal. Tiny channels in neurons help formulate that signal, but scientists know little of the details of how these channels work. New research has revealed that one such channel in humans uses a never-before-seen mechanism.  |
| Oldest ever engraving discovered on 500,000-year-old shell Posted: 03 Dec 2014 11:24 AM PST Homo erectus on Java was already using shells of freshwater mussels as tools half a million years ago, and as a 'canvas' for an engraving. The discovery of an engraved geometrical pattern on one of the shells came as a total surprise. The zig zag pattern, that can only be seen with oblique lighting, is clearly older than the weathering processes on the shell arising from fossilization.  |
| Small drains mean big problems at 'baby beaches' Posted: 03 Dec 2014 09:53 AM PST High fecal counts frequently detected at so-called 'baby beaches' may not be diaper-related. Researchers found that during summer months, small drainpipes emptying into enclosed ocean bays have a disproportionate impact on calmer waters.  |
| Mapping human disease: 'Not all pathogens are everywhere' Posted: 03 Dec 2014 09:53 AM PST For the first time, researchers have mapped human disease-causing pathogens, dividing the world into a number of regions where similar diseases occur. The findings show that the world can be separated into seven regions for vectored human diseases -- diseases that are spread by pests, like mosquito-borne malaria -- and five regions for non-vectored diseases, like cholera.  |
| Tinkering with the Tao of pandas Posted: 03 Dec 2014 09:53 AM PST Good news on the panda front: Turns out they're not quite as delicate -- and picky -- as thought. Up until now, information gleaned from 30 years worth of scientific literature suggested that pandas were inflexible about habitat. Those conclusions morphed into conventional wisdom and thus have guided policy in China. But a new researcher has led a deep dive into aggregate data and emerged with evidence that the endangered animal is more resilient and flexible than previously believed.  |
| Low-grade waste heat regenerates ammonia battery Posted: 03 Dec 2014 09:53 AM PST An efficient method to harvest low-grade waste heat as electricity may be possible using reversible ammonia batteries, according to engineers. Low-grade waste heat is an artifact of many energy-generating methods. In automobiles, waste heat generated in winter is diverted to run the vehicle heating system, but in the summer, that same waste heat must be dissipated to the environment.  |
| Geckos are sticky without effort: Death has no impact on strength geckos use to adhere to surfaces Posted: 03 Dec 2014 09:53 AM PST Scientists have studied a variety of features in geckos such as the adhesive toe pads on the underside of the feet with which geckos attach to surfaces with remarkable strength. Biologists have now conducted experiments in the lab on live and dead geckos that show, for the first time, that dead geckos can adhere to surfaces with the same strength as living geckos. The research could have applications in the field of robotics.  |
| People in unhappy places are depressed more than a week a month Posted: 03 Dec 2014 09:53 AM PST People in the country's unhappiest communities spend about a quarter of the month so far down in the dumps that it can harm their productivity, according to economists.  |
| Glass houses: Your personality helps predict your real estate choices Posted: 03 Dec 2014 09:51 AM PST According to a new study, personality traits are strong indicators of real-estate decisions. The study finds a correlation between personality and individual real estate choices, and a follow-up study by the same team finds an identical link between local personality types in America and statewide real estate trends.  |
| Clothes that can monitor, transmit biomedical info developed Posted: 03 Dec 2014 09:51 AM PST Smart textiles are able to monitor and transmit wearers' biomedical information via wireless or cellular networks, developers report. This technological breakthrough clears a path for a host of new developments for people suffering from chronic diseases, elderly people living alone, and even firemen and police officers.  |
| Are There Safe, Effective Treatments for Hereditary Angioedema in Children? Posted: 03 Dec 2014 09:50 AM PST Hereditary angioedema (HAE), a rare genetic disease that causes recurrent swelling under the skin and of the mucosal lining of the gastrointestinal tract and upper airway, usually first appears before 20 years of age. A comprehensive review of the therapies currently available to treat HAE in adults shows that some of these treatments are also safe and effective for use in older children and adolescents.  |
| Extraordinary throughput at supercomputing conference Posted: 03 Dec 2014 09:48 AM PST Computer scientists moved 65 terabytes of data in under just 100 minutes at a recent supercomputing conference.  |
| Online tool to help cities in Great Lakes Region plan for climate impacts Posted: 03 Dec 2014 09:48 AM PST Reduced water availability and quality, floods and problems related to heat stress are some of the potential impacts cities face with a changing climate.  |
| 'Mirage Earth' exoplanets may have burned away chances for life Posted: 03 Dec 2014 09:48 AM PST Planets orbiting close to low-mass stars — easily the most common stars in the universe — are prime targets in the search for extraterrestrial life. But new research led by an astronomy graduate student indicates some such planets may have long since lost their chance at hosting life because of intense heat during their formative years.  |
| Managing reefs to benefit coastal communities Posted: 03 Dec 2014 08:12 AM PST Coral reefs provide a range of benefits, such as food, opportunities for income and education, but not everyone has the same access to them, according to a new study.  |
| A glimmer of hope for corals as baby reef builders cope with acidifying oceans Posted: 03 Dec 2014 08:12 AM PST While the threat of coral bleaching as a result of climate change poses a serious risk to the future of coral reefs worldwide, new research has found that some baby corals may be able to cope with the negative effects of ocean acidification.  |
| New molecules to burst malaria's bubble Posted: 03 Dec 2014 08:12 AM PST Scientists have released details of a raft of new chemicals with potent anti-malarial properties which could open the way to new drugs to fight malaria. Over 200 million people contract malaria each year, and the parasite that causes the disease has become resistant to most of the drugs currently available. The papers show the malaria parasite has real Achilles heel, and we now have range of new ways to attack it.  |
| Fractal geometry: Finding the simple patterns in a complex world Posted: 03 Dec 2014 08:12 AM PST A mathematician has developed a new way to uncover simple patterns that might underlie apparently complex systems, such as clouds, cracks in materials or the movement of the stockmarket. The method, named fractal Fourier analysis, is based on new branch of mathematics called fractal geometry. The method could help scientists better understand the complicated signals that the body gives out, such as nerve impulses or brain waves.  |
| Toward a low-cost 'artificial leaf' that produces clean hydrogen fuel Posted: 03 Dec 2014 08:11 AM PST For years, scientists have been pursuing 'artificial leaf' technology, a green approach to making hydrogen fuel that copies plants' ability to convert sunlight into a form of energy they can use. Now, one team reports progress toward a stand-alone system that lends itself to large-scale, low-cost production. They created a nanowire mesh design.  |
| Novel approach to treating asthma: Neutralize the trigger Posted: 03 Dec 2014 08:11 AM PST Current asthma treatments can alleviate wheezing, coughing and other symptoms felt by millions of Americans every year, but they don't get to the root cause of the condition. Now, for the first time, scientists are reporting a new approach to defeating asthma by targeting the trigger -- the allergen -- before it can spark an attack.  |
| Gut bacteria from a worm can degrade plastic Posted: 03 Dec 2014 08:11 AM PST Plastic is well-known for sticking around in the environment for years without breaking down, contributing significantly to litter and landfills. But scientists have now discovered that bacteria from the guts of a worm known to munch on food packaging can degrade polyethylene, the most common plastic.The finding could lead to new ways to help get rid of the otherwise persistent waste, the scientists say.  |
| Space travel is a bit safer than expected Posted: 03 Dec 2014 08:11 AM PST Analysis of data from the MATROSHKA experiment, the first comprehensive measurements of long-term exposure of astronauts to cosmic radiation, has now been completed. This experiment, carried out on board and outside of the International Space Station, showed that the cosmos may be less hostile to space travelers than expected.  |
| People conceived during Dutch famine have altered regulation of growth genes Posted: 03 Dec 2014 08:09 AM PST Individuals conceived in the severe Dutch Famine may have adjusted to this horrendous period of World War II by making adaptations to how active their DNA is. Genes involved in growth and development were differentially regulated, according to researchers. Extensive research on the DNA of these children shows that the regulatory systems of their growth genes were altered, which may also explain why they may be at higher risk for metabolic disease in later life.  |
| Human influence important factor in possible global and UK temperature records Posted: 03 Dec 2014 08:08 AM PST Early figures show 2014 is on course to be one of, if not the warmest year on record both globally and for the UK.  |
| More Hispanics earning bachelor's degrees in physical sciences and engineering Posted: 03 Dec 2014 08:07 AM PST The number of Hispanic students receiving bachelor's degrees in the physical sciences and engineering has increased over the last decade or so, passing 10,000 degrees per year for the first time in 2012. The overall number of U.S. students receiving degrees in those fields also increased over the same time, but it increased faster among Hispanics.  |
| Cancer Prevalent in Pets but Treatable, Says Veterinarian Posted: 03 Dec 2014 08:07 AM PST Common cancers in humans are also common cancers in pets. A veterinarian lays out the warning signs that could indicate your dog or cat has cancer.  |
| Posted: 03 Dec 2014 07:01 AM PST What do lasers, neural networks, and spreading epidemics have in common? They share a most basic feature whereby an initial pulse can propagate through a medium - be it physical, biological or socio-economic, respectively. The challenge is to gain a better understanding - and eventually control - of such systems, allowing them to be applied, for instance to real neural systems. This is the objective of a new theoretical study.  |
| Ultrasound cuts costs in producing aluminium alloys Posted: 03 Dec 2014 07:01 AM PST Scientists have confirmed that treating molten metal with ultrasound is a cleaner, greener and more efficient route to produce high quality castings.  |
| Green meets Nano: Scientists create multifunctional nanotubes using nontoxic materials Posted: 03 Dec 2014 07:01 AM PST A doctoral student in materials science is making multifunctional nanotubes of gold – with the help of vitamin C and other harmless substances.  |
| Posted: 03 Dec 2014 07:01 AM PST Polylactic acid is a degradable plastic used mostly for packaging. To meet the rising demand, researchers have developed an eco-friendly process to make large amounts of lactic acid from glycerol, a waste by-product in the production of biodiesel.  |
| Chemo effect on brain cells pinpointed; potential link to autism Posted: 03 Dec 2014 07:00 AM PST Scientists discovered how the chemo drug topotecan affects individual neurons to potentially cause "chemo fog." A similar long-term affect in the developing brain could trigger autism. "There's still a question in the cancer field about the degree to which some chemotherapies get into the brain," said a co-senior author of the paper. "But in our experiments, we show that if they do get in, they can have a dramatic effect on synaptic function. We think drug developers should be aware of this when testing their next generation of topoisomerase inhibitors."  |
| Movements Help Measure Child Sleep Problems Posted: 03 Dec 2014 07:00 AM PST Light has been shed on the complexities of child sleep, and could lead to improved diagnosis of children with sleep-related breathing problems. "Quality sleep is extremely important for children, especially at critical times of development. It can impact on the health of the brain and plays a key role in language development, for example. Poor quality sleep can result in reduced IQ, school performance and can impact overall quality of life," says the lead author.  |
| Macho stereotypes put off men as well as women Posted: 03 Dec 2014 05:43 AM PST Some men are being driven away from macho occupations like surgery and the Royal Marines because they don't feel that they are 'man enough', according to new research.  |
| Growing cooperation: First the carrot, then the stick Posted: 03 Dec 2014 05:43 AM PST To encourage cooperation in groups, a combination of rewards and penalties is best, according to a new study.  |
| Carbon dioxide warming effects felt just a decade after being emitted Posted: 03 Dec 2014 05:43 AM PST It takes just 10 years for a single emission of carbon dioxide (CO2) to have its maximum warming effects on the Earth. This is according to researchers who have dispelled a common misconception that the main warming effects from a CO2 emission will not be felt for several decades.  |
| Diagnosis targets in primary care are misleading, unethical, UK experts say Posted: 03 Dec 2014 05:42 AM PST Last month, there was public outcry at the news that GPs in England would be paid £55 for each case of dementia diagnosed. Now come targets for six other conditions, including diabetes coronary heart disease, asthma and depression, writes an English GP. "But the data on which they are based are flawed, and the approach incentivises potentially harmful overdiagnosis," he argues.  |
| Overweight and obesity in pregnancy linked to greater risk of infant death Posted: 03 Dec 2014 05:42 AM PST Overweight and obesity in early pregnancy are associated with increased risks of infant mortality, with the greatest risks seen among severely obese mothers, finds a study.  |
| Mediterranean diet linked to longer life Posted: 03 Dec 2014 05:42 AM PST Eating a Mediterranean diet might help extend your lifespan, suggests a study. The diet appears to be associated with longer telomere length -- an established marker of slower aging.  |
| Study of deadly bat disease finds surprising seasonal pattern of infections Posted: 03 Dec 2014 05:41 AM PST The deadly fungal disease known as white-nose syndrome has spread to bat colonies throughout eastern North America over the past seven years, causing bat populations to crash, with several species now at risk of extinction. The devastating impact of this disease is due in part to the seasonal dynamics of infection and transmission, according to a new study.  |
| Brain study uncovers new clues on how cues may affect memory Posted: 03 Dec 2014 05:40 AM PST The brain activity prior to seeing an item is related to how well it is later remembered, a new study shows. Moreover, researchers also found that the activity in different areas of the brain was unexpectedly related to how the information was remembered.  |
| Computer model enables design of complex DNA shapes Posted: 03 Dec 2014 05:40 AM PST Biological engineers have created a new computer model that allows them to design the most complex three-dimensional DNA shapes ever produced, including rings, bowls, and geometric structures such as icosahedrons that resemble viral particles.  |
| Many chest X-rays in children are unnecessary Posted: 03 Dec 2014 05:40 AM PST Some children are receiving chest X-rays that may be unnecessary and offer no clinical benefit to the patient, according to a new study. "Chest X-rays can be a valuable exam when ordered for the correct indications," said a radiologist. "However, there are several indications where pediatric chest X-rays offer no benefit and likely should not be performed to decrease radiation dose and cost."  |
| Posted: 03 Dec 2014 05:39 AM PST However, although some cancers have a good prognosis, the outlook for others remains extremely poor. For example, while 98% of men with testicular cancer survive from their cancer for at least a decade after diagnosis, up from 69% 40 years ago, just 1% of pancreatic cancer patients diagnosed today are expected to survive from their cancer 10 years.  |
| Animal welfare could be improved by new understanding of their emotions Posted: 03 Dec 2014 05:39 AM PST New research looking at how goats express subtle positive emotions could lead to greater understanding of animal welfare. While there has been a great deal of research into negative emotions and stress in animals it is often hard for those who work with animals to know when they are in more subtle positive states.  |
| Increased production not the way to grow the economy Posted: 03 Dec 2014 05:39 AM PST Continued economic growth requires an alarming – and arguably unsustainable – amount of raw material and energy. But what if there was a way to rein in production, without slowing down the economy?  |
| Colorful nano-guides to the liver Posted: 03 Dec 2014 05:39 AM PST Highly specific nanoparticles have been produced by scientists. Depending on the bound dye the particles are guided to the liver or to the kidney and deliver their payload of active ingredients directly to the targeted tissue. Moreover, the dyes enable the tracking of the transport processes by intravital microscopy or, in a non-invasive way, by multi spectral optoacoustic tomography. The reduction of cholesterol production induced by siRNA served as the proof-of-principle for the developed method.  |
| Astronomers detect atomic hydrogen emission in galaxies at record breaking distances Posted: 03 Dec 2014 05:38 AM PST Using the world's largest radio telescope, astronomers have detected the faint signal emitted by atomic hydrogen gas in galaxies three billion light years from Earth, breaking the previous record distance by 500 million light years.  |
| Does your boss find you proactive…or pushy? Posted: 03 Dec 2014 05:38 AM PST Those wishing to prove themselves as "doers" must not only be hands-on and demonstrate proactive behavior but also have social acumen and a feel for favorable opportunities. Those who rely on personal initiative alone will quickly be standing there as an isolated troublemaker. This is what psychologists have discovered through surveying a variety of occupational categories.  |
| Shark-shaped sampler to hunt down 'fugitive' air pollution Posted: 03 Dec 2014 05:38 AM PST Industrial sites and highways could become cleaner in the future thanks to shark-shaped samplers that hunt 'fugitive' air pollutants.  |
| Smart anti-icing system for rotor blades Posted: 03 Dec 2014 05:38 AM PST In very cold climate zones, the wind can blow with tremendous force. But wind turbines have rarely been built in these regions up to now. The risk of ice formation on the rotor blades is just too high. But now, an energy-efficient heating system frees these turbines from the ice in a matter of seconds. It is only switched on when water freezes.  |
| New study explains the role of oceans in 'global warming hiatus' Posted: 03 Dec 2014 05:37 AM PST New research shows that ocean heat uptake across three oceans is the likely cause of the 'warming hiatus' – the current decade-long slowdown in global surface warming. Using data from a range of state-of-the-art ocean and atmosphere models, the research shows that the increased oceanic heat drawdown in the equatorial Pacific, North Atlantic and Southern Ocean basins has played a significant role in the hiatus.  |
| Brain research reveals new hope for patients with anorexia nervosa Posted: 03 Dec 2014 05:37 AM PST Researchers used state-of-the-art magnetic resonance imaging (MRI) techniques to investigate the consequences of anorexia nervosa on brain structure. Their novel findings obtained by measuring "cortical thickness" for the first time in the eating disorder are now published. The authors conclude, "The global thinning of cortical gray matter observed in acutely ill adolescent patients can be completely reversed following successful weight rehabilitation therapy".  |
| Perfect chocolate sheen on confection, sweets Posted: 03 Dec 2014 05:37 AM PST White flecks on sweets with a chocolate glaze are harmless – but esthetically unappealing. More than just improper storage can diminish the glossy sheen. Researchers have discovered other weak points in the production process. Armed with sophisticated analysis, companies can now protect their products effectively from the undesirable coating.  |
| You can hear the coral reefs dying, experts say Posted: 03 Dec 2014 05:37 AM PST You can hear the sound of former bustling coral reefs dying due to the impact of human activity, according to new research. Scientists have found that coral reefs impacted by human activity, such as overfishing, are much quieter than protected reefs, which can have a big impact on the fish and invertebrates which rely on the reefs for survival.  |
| Posted: 03 Dec 2014 05:37 AM PST With good planning, it is possible to promote the reuse of construction and demolition waste and thereby both conserve the environment and save on material costs. In the future, it will be even more important to assess how buildings can reasonably be repaired or demolished into parts, together with how the remaining service life of the parts can be utilized in new applications. The best method is to implement demolition planning already as a component of construction design.  |
| Mapping the interactome: Proteomics reveals the E-cadherin interaction network Posted: 03 Dec 2014 05:37 AM PST Researchers have comprehensively described the network of proteins involved in cell-cell adhesions, or the cadherin interactome. Many biological processes depend on the ability of cells to stick to one another. The formation of multicellular organisms and precise embryonic development rely on this property, as does the maintenance of healthy tissue.  |
| Posted: 03 Dec 2014 05:36 AM PST Detection, prevention, and preclinical treatment are three key areas that may make a difference in the battle to reduce the rapid rise of new Alzheimer's disease (AD) cases every year. These three topics are the focus of a new journal supplement.  |
