| Newborns exposed to dirt, dander, germs may have lower allergy, asthma risk Posted: 06 Jun 2014 06:11 AM PDT Infants exposed to rodent and pet dander, roach allergens and a wide variety of household bacteria in the first year of life appear less likely to suffer from allergies, wheezing and asthma, according to results of a recent study. Those who encounter such substances before their first birthdays seem to benefit rather than suffer from them. Importantly, the protective effects of both allergen and bacterial exposure were not seen if a child's first encounter with these substances occurred after age 1, the research found. |
| Turbulent black holes: Fasten your seatbelts ... gravity is about to get bumpy! Posted: 05 Jun 2014 12:57 PM PDT Gravitational fields around black holes might eddy and swirl. Fasten your seatbelts -- gravity is about to get bumpy. Of course, if you're flying in the vicinity of a black hole, a bit of extra bumpiness is the least of your worries. But it's still surprising. The accepted wisdom among gravitational researchers has been that spacetime cannot become turbulent. New research though, shows that the accepted wisdom might be wrong. |
| Gene study shows how sheep first separated from goats Posted: 05 Jun 2014 11:18 AM PDT Scientists have cracked the genetic code of sheep to reveal how they became a distinct species from goats around four million years ago. The study is the first to pinpoint the genetic differences that make sheep different from other animals. |
| Fasting triggers stem cell regeneration of damaged, old immune system Posted: 05 Jun 2014 11:15 AM PDT In the first evidence of a natural intervention triggering stem cell-based regeneration of an organ or system, a study shows that cycles of prolonged fasting not only protect against immune system damage -- a major side effect of chemotherapy -- but also induce immune system regeneration, shifting stem cells from a dormant state to a state of self-renewal. |
| A new way to make laser-like beams using 1,000 times less power Posted: 05 Jun 2014 11:01 AM PDT With precarious particles called polaritons that straddle the worlds of light and matter, researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam. |
| What a 66-million-year old forest fire reveals about the last days of the dinosaurs Posted: 05 Jun 2014 11:01 AM PDT As far back as the time of the dinosaurs, 66 million years ago, forests recovered from fires in the same manner they do today, according to a researchers. During an expedition in southern Saskatchewan, Canada, the team discovered the first fossil-record evidence of forest fire ecology -- the regrowth of plants after a fire -- revealing a snapshot of the ecology on earth just before the mass extinction of the dinosaurs. |
| Molecular secret of short, intense workouts clarified Posted: 05 Jun 2014 08:35 AM PDT The benefits of short, intense workouts have been extolled as a metabolic panacea for greater overall fitness, better blood sugar control and weight reduction. Scientists confirm something is molecularly unique about intense exercise: the activation of a single protein. The new findings open the door to a range of potential exercise enhancements. |
| Research on marijuana's negative health effects summarized in report Posted: 05 Jun 2014 06:33 AM PDT The current state of science on the adverse health effects of marijuana use links the drug to several significant adverse effects including addiction, a review reports. The review describes the science establishing that marijuana can be addictive and that this risk for addiction increases for daily or young users. It also offers insights into research on the gateway theory indicating that marijuana use, similar to nicotine and alcohol use, may be associated with an increased vulnerability to other drugs. |
| Looking for the best strategy? Ask a chimp Posted: 05 Jun 2014 05:35 AM PDT If you're trying to outwit the competition, it might be better to have been born a chimpanzee, according to a new study which found that chimps consistently outperform humans in simple contests drawn from game theory. |
| Scientist uses fossils to prove historic Ohio millstones have French origins Posted: 04 Jun 2014 11:13 AM PDT A geologist studied fossils to confirm that stones used in 19th century Ohio grain mills originated from France. Fossils embedded in these millstones were analyzed to determine that stones known as French buhr were imported from regions near Paris, France, to Ohio in the United States. |

| Health policy researchers lack confidence in social media for communicating scientific evidence Posted: 06 Jun 2014 10:54 AM PDT Though Twitter boats 645 million users across the world, only 14 percent of health policy researchers reported using Twitter – and approximately 20 percent used blogs and Facebook – to communicate their research findings over the past year, according to a new study. In contrast, sixty-five percent used traditional media channels, such as press releases or media interviews. While participants believed that social media can be an effective way to communicate research findings, many lacked the confidence to use it and felt their academic peers and institutions did not value it or respect it as much as traditional media and direct contact with policy makers. |
| Evolution of a bimetallic nanocatalyst Posted: 06 Jun 2014 10:14 AM PDT Atomic-scale snapshots of a bimetallic nanoparticle catalyst in action have provided insights that could help improve the industrial process by which fuels and chemicals are synthesized from natural gas, coal or plant biomass. |
| Opening a wide window on the nano-world of surface catalysis Posted: 06 Jun 2014 07:20 AM PDT A surface catalyst with a built-in sensor: that's what chemists built by bridging a size gap on the nano-scale. Their silver nanoparticles combine plasmon resonance with catalytic activity, making SERS and other analytical data available in real time on a surface catalyst. |
| Shatterproof screens that save smartphones Posted: 06 Jun 2014 07:20 AM PDT Researchers have demonstrated how a transparent layer of electrodes on a polymer surface could be extraordinarily tough and flexible, withstanding repeated Scotch tape peeling and bending tests. |
| Method of synthesizing new type of nickel-carbon heterofullerenes Posted: 06 Jun 2014 07:20 AM PDT Scientists have come up with a method of synthesizing a new type of nickel-carbon compound. Heterofullerenes are hollow molecules with a nearly-spherical shape, which, unlike the typical fullerenes, contain atoms of elements other than carbon. Such compounds were synthesized quite a while ago, in 1991, but till now no heterofullerenes containing nickel, or any other transition metal, have been obtained. |
| Magnetic moment of the proton measured with unprecedented precision Posted: 06 Jun 2014 07:19 AM PDT Physicists succeeded in the first direct high-precision measurement of a fundamental property of the proton. Results will contribute to a better understanding of the matter/antimatter asymmetry. |
| Drastic cut in electricity bill for supermarket in Norway Posted: 06 Jun 2014 06:15 AM PDT A newly built mini-supermarket was opened last autumn in Norway by a government minister to the sound of a brass band. Throughout the winter, it used 30 per cent less electricity than four comparable stores in the capital of mid-Norway, where of course the outdoor temperature was the same for all of them. |
| New diagnostic imaging techniques deemed safe in simulations Posted: 04 Jun 2014 10:37 AM PDT Gamma and neutron imaging offer possible improvements over existing techniques such as X-ray or CT, but their safety is not yet fully understood. Using computer simulations, imaging the liver and breast with gamma or neutron radiation was found to be safe, delivering levels of radiation on par with conventional medical imaging, according to researchers. |
| Count of new CFCs in the atmosphere rises from four to seven Posted: 03 Jun 2014 04:39 PM PDT Two new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been found in the atmosphere by a group of scientists. Scientists made the discovery by comparing today's air samples with air collected between 1978 and 2012 in unpolluted Tasmania, and samples taken during aircraft flights. Measurements show that all but one of the new gases have been released into the atmosphere in recent years. |

| HIV transmission networks mapped to reduce infection rate Posted: 06 Jun 2014 06:18 AM PDT The transmission network of human immunodeficiency virus (HIV) has been mapped in San Diego. The mapping of HIV infections, which used genetic sequencing, allowed researchers to predictively model the likelihood of new HIV transmissions and identify persons at greatest risk for transmitting the virus. |
| Infection in malaria-transmitting mosquito discovered Posted: 06 Jun 2014 06:11 AM PDT The first evidence of an intercellular bacterial infection in natural populations of two species of Anopheles mosquitoes, the major vectors of malaria in Africa, has been found by scientists. The infection, called Wolbachia, has been shown in labs to reduce the incidence of pathogen infections in mosquitoes and has the potential to be used in controlling malaria-transmitting mosquito populations. |
| Posted: 05 Jun 2014 03:36 PM PDT Over the last two decades, spurred by higher temperatures caused by climate change, scientists say, forests throughout the Eastern US have experienced earlier springs and later autumns than ever before.

| Climate change: Termites, fungi play more important role in decomposition than temperature Posted: 05 Jun 2014 03:36 PM PDT Climate change models could have a thing or two to learn from termites and fungi, according to a new study. For a long time scientists have believed that temperature is the dominant factor in determining the rate of wood decomposition worldwide. Decomposition matters because the speed at which woody material are broken down strongly influences the retention of carbon in forest ecosystems and can help to offset the loss of carbon to the atmosphere from other sources. That makes the decomposition rate a key factor in detecting potential changes to the climate. |
| New evidence links air pollution to autism, schizophrenia Posted: 05 Jun 2014 12:57 PM PDT A new study describes how exposure to air pollution early in life produces harmful changes in the brains of mice, including an enlargement of part of the brain that is seen in humans who have autism and schizophrenia. The mice performed poorly in tests of short-term memory, learning ability, and impulsivity. Study authors say the findings are very suggestive that air pollution may play a role in autism, as well as in other neurodevelopmental disorders. |
| Brain circuit problem likely sets stage for the 'voices' that are symptom of schizophrenia Posted: 05 Jun 2014 11:19 AM PDT Scientists have identified problems in a connection between brain structures that may predispose individuals to hearing the 'voices' that are a common symptom of schizophrenia. Researchers linked the problem to a gene deletion. This leads to changes in brain chemistry that reduce the flow of information between two brain structures involved in processing auditory information. |
| On-off switch to burning stored fat found by scientists Posted: 05 Jun 2014 11:19 AM PDT Scientists' discovery of how white fat cells are converted to beige, and the on-off switch for the process, could lead to novel diabetes and obesity drugs. "Understanding how beigeing is controlled is so very important because if we can improve energy expenditure, we can reduce obesity," the lead author said. |
| Posted: 05 Jun 2014 11:17 AM PDT Scientists have new evidence in mice that it may be possible to repair a chronically diseased liver by forcing mature liver cells to revert back to a stem cell-like state. The researchers happened upon this discovery while investigating whether a biochemical cascade called Hippo, which controls how big the liver grows, also affects cell fate. The unexpected answer is that switching off the Hippo-signaling pathway in mature liver cells generates very high rates of dedifferentiation. This means the cells turn back the clock to become stem-cell like again, thus allowing them to give rise to functional progenitor cells that can regenerate a diseased liver. |
