| Choosing cheese: Research identifies microbial communities in cheese Posted: 17 Jul 2014 03:05 PM PDT After studying 137 varieties of cheese collected in 10 different countries, researchers have been able to identify three general types of microbial communities that live on cheese, opening the door to using each as a 'model' community for the study of whether and how various microbes and fungi compete or cooperate as they form communities, what molecules may be involved in the process and what mechanisms may be involved.  |
| Adolescent alcohol abuse disrupts transitions into early adulthood Posted: 17 Jul 2014 03:04 PM PDT Adolescent alcohol abuse is known to be associated with adverse outcomes in early adulthood. It is unclear how much of this association is due to the influence of differences in familial background and shared genetics. New findings implicate a significant causal relationship between elevated drinking problems at age 18.5 and more adverse life outcomes at age 25 that cannot be fully explained by shared genetic and environmental liabilities.  |
| Fish oil may benefit alcohol abusers Posted: 17 Jul 2014 03:02 PM PDT Omega-3 fish oil might help protect against alcohol-related neurodamage and the risk of eventual dementia, according to a study. Many human studies have shown that long-term alcohol abuse causes brain damage and increases the risk of dementia. The new study found that in brain cells exposed to high levels of alcohol, a fish oil compound protected against inflammation and neuronal cell death.  |
| Preventing foodborne illness naturally: with cinnamon Posted: 17 Jul 2014 06:51 AM PDT Cinnamomum cassia oil was shown to be effective as a natural antibacterial agent against several strains of Shiga toxin-producing Escherichia coli, known to the US Centers for Disease Control and Prevention as 'non-O157 STEC'. The study results add to a body of knowledge that will help improve food safety and reduce or eliminate cases of food poisoning and related deaths.  |
| Keeping a promise worth more than exceeding it Posted: 17 Jul 2014 06:45 AM PDT Exceeding a promise isn't viewed any more highly than keeping a promise, a study has demonstrated. Researchers thus suggest that there is little or no benefit to putting forth a greater effort to exceed a promise when keeping a promise is so highly valued. This likely extends beyond interpersonal relationships, the researchers write, to relationships between businesses and customers, and employers and employees.  |
| Does practice really make perfect? Posted: 16 Jul 2014 09:38 AM PDT Does practice really make perfect? It's an age-old question, and a new study finds that while practice won't make you perfect, it will usually make you better at what you're practicing. "Other factors matter as well, but even so, no one says that practice will ever hurt you; but be careful if you are walking tightropes," one researcher said.  |
| Adolescent males seek intimacy, close relationships with the opposite sex Posted: 15 Jul 2014 11:28 AM PDT Teenage boys desire intimacy and sex in the context of a meaningful relationship and value trust in their partnerships, according to researchers. The research provides a snapshot of the development of masculine values in adolescence, an area that has been understudied.  |

| Cheap, highly efficient solar cells: A new stable and cost-cutting type of perovskite solar cell Posted: 17 Jul 2014 12:15 PM PDT Scientists have made a very efficient perovskite solar cell that does not require a hole-conducting layer. The novel photovoltaic achieved energy conversion efficiency of 12.8 percent and was stable for over 1000 hours under full sunlight. The innovation is expected to significantly reduce the cost of these promising solar cells.  |
| Posted: 17 Jul 2014 11:20 AM PDT The largest-ever phylogenetic study of spiders shows that, contrary to long-held popular opinion, the two groups of spiders that weave orb-shaped webs do not share a single origin.  |
| Posted: 17 Jul 2014 11:20 AM PDT Using the largest laser in the world, scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets, such as Jupiter, Uranus and many of the planets recently discovered outside our solar system.  |
| How existing cropland could feed billions more Posted: 17 Jul 2014 11:19 AM PDT Feeding a growing human population without increasing stresses on Earth's strained land and water resources may seem like an impossible challenge. But according to a new report focusing efforts to improve food systems on a few specific regions, crops and actions could make it possible to both meet the basic needs of 3 billion more people and decrease agriculture's environmental footprint.  |
| Posted: 17 Jul 2014 09:50 AM PDT Soil deep in a crater dating to some 3.7 billion years ago contains evidence that Mars was once much warmer and wetter, says a geologist based on images and data captured by the rover Curiosity.  |
| Is the universe a bubble? Let's check: Making the multiverse hypothesis testable Posted: 17 Jul 2014 09:48 AM PDT Scientists are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never mind the Big Bang; in the beginning was the vacuum. The vacuum simmered with energy (variously called dark energy, vacuum energy, the inflation field, or the Higgs field). Like water in a pot, this high energy began to evaporate -- bubbles formed.  |
| Eye movements reveal difference between love and lust Posted: 17 Jul 2014 09:45 AM PDT A new study suggests the difference between love and lust might be in the eyes. Specifically, where your date looks at you could indicate whether love or lust is in the cards. The new study found that eye patterns concentrate on a stranger's face if the viewer sees that person as a potential partner in romantic love, but the viewer gazes more at the other person's body if he or she is feeling sexual desire.  |
| Danish DNA could be key to happiness Posted: 17 Jul 2014 06:48 AM PDT Genetics could be the key to explaining nation's levels of happiness, according to new research. Economists have found the closer a nation is to the genetic makeup of Denmark, the happier that country is. The research could help to solve the puzzle of why a country like Denmark so regularly tops the world happiness rankings.  |
| Are ants the answer to carbon dioxide sequestration? Posted: 16 Jul 2014 03:31 PM PDT A 25-year-long study provides the first quantitative measurement of in situ calcium-magnesium silicate mineral dissolution by ants, termites, tree roots, and bare ground. This study reveals that ants are one of the most powerful biological agents of mineral decay yet observed. It may be that an understanding of the geobiology of ant-mineral interactions might offer a line of research on how to "geoengineer" accelerated carbon dioxide consumption by Ca-Mg silicates.  |
| Humans walking on all fours is not backward evolution Posted: 16 Jul 2014 12:11 PM PDT Five siblings in the family, who live in a remote corner of Turkey, walk exclusively on their hands and feet. Since they were discovered in 2005, scientists have debated the nature of their disability, with speculation they represent a backward stage of evolution. An anthropologist finds quadrupedal humans with Uner Tan Syndrome do not walk in the diagonal pattern characteristic of nonhuman primates such as apes and monkeys.  |
| Sharpest map of Mars surface properties Posted: 16 Jul 2014 11:13 AM PDT A heat-sensing camera has provided data to create the most detailed global map yet made of Martian surface properties. Surface properties tell geologists about the physical nature of a planet or moon's surface. Is a particular area coated with dust, and if so, how thick is it likely to be? Where are the outcrops of bedrock? How loose are the sediments that fill this crater or that valley? A map of surface properties lets scientists begin to answer questions such as these.  |
| Tooth plaque provides unique insights into our prehistoric ancestors' diet Posted: 16 Jul 2014 11:10 AM PDT An international team of researchers has found new evidence that our prehistoric ancestors had a detailed understanding of plants long before the development of agriculture. By extracting chemical compounds and microfossils from dental calculus (calcified dental plaque) from ancient teeth, the researchers were able to provide an entirely new perspective on our ancestors' diets. Their research suggests that purple nut sedge (Cyperus rotundus) -- today regarded as a nuisance weed -- formed an important part of the prehistoric diet.  |
| Asteroid Vesta to reshape theories of planet formation Posted: 16 Jul 2014 10:16 AM PDT Researchers have a better understanding of the asteroid Vesta and its internal structure, thanks to numerical simulations and data from the space mission Dawn. Their findings question contemporary models of rocky planet formation, including that of Earth.  |
| Brain of world's first known predators discovered Posted: 16 Jul 2014 10:16 AM PDT Scientists have found the fossilized remains of the brain of the world's earliest known predators, from a time when life teemed in the oceans but had not yet colonized the land. The discovery reveals a brain much simpler than those known in some of the animal's prey and helps answer questions surrounding the evolution of arthropods.  |
| Scientists find way to trap, kill malaria parasite Posted: 16 Jul 2014 10:15 AM PDT Scientists may be able to entomb the malaria parasite in a prison of its own making, researchers report. As it invades a red blood cell, the malaria parasite takes part of the host cell's membrane to build a protective compartment. The parasite then starts a series of major renovations that transform the red blood cell into a suitable home. But the new research reveals the proteins that make these renovations must pass through a single pore in the parasite's compartment to get into the red blood cell. When the scientists disrupted passage through that pore in cell cultures, the parasite stopped growing and died.  |
| Mediterranean diet has varied effects on cognitive decline among different races, study shows Posted: 16 Jul 2014 09:38 AM PDT "In a population of initially well-functioning older adults, we found a significant correlation between strong adherence to the Mediterranean diet and a slower rate of cognitive decline among African American, but not white, older adults. Our study is the first to show a possible race-specific association between the Mediterranean diet and cognitive decline," a researcher outlines.  |
| Marijuana dependence alters the brain's response to drug paraphernalia Posted: 16 Jul 2014 06:08 AM PDT New research demonstrates that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users. By letting users handle a marijuana pipe while in an fMRI, researchers found that areas of brain activation in the dependent users suggests a more emotional connection than in non-dependent users. Non-dependent users had greater activations in areas associated with memory and attention.  |

| The bend in the Appalachian mountain chain is finally explained Posted: 18 Jul 2014 08:56 AM PDT The 1500 mile Appalachian mountain chain runs along a nearly straight line from Alabama to Newfoundland -- except for a curious bend in Pennsylvania and New York State. Researchers now know what caused that bend -- a dense, underground block of rigid, volcanic rock forced the chain to shift eastward as it was forming millions of years ago.       |
| Microplastics worse for crabs and other marine life than previously thought: Enter through gills Posted: 18 Jul 2014 08:56 AM PDT The tiny plastic particles polluting our seas are not only orally ingested by marine creatures, but also enter their systems through their gills, according to a new study. When microplastics are drawn in through this method they take over six times longer to leave the body compared with standard digestion.  |
| Essential Oils May Provide Good Source of Food Preservation Posted: 18 Jul 2014 08:45 AM PDT Essential oils may be able to be used as food preservatives in packaging to help extend the shelf-life of food products, a new study suggests. Essential oils are aromatic oily liquids extracted from different parts of plants (roots, peels, leaves, seeds, fruits, barks) and have been shown to be a good source of antioxidative and antimicrobial properties.  |
| New cellular garbage control pathway with relevance for human neurodegenerative diseases Posted: 18 Jul 2014 08:04 AM PDT Several human neurodegenerative diseases, including Alzheimer's, Parkinson's and Huntington's disease, are linked to an accumulation of abnormal and aggregated proteins in cells. Cellular 'garbage' can be removed from cells by sweeping them to a cellular recycling station known as the lysosome. Scientists have now discovered a new family of helper proteins that recognize labeled protein waste and guide them efficiently to the lysosome for destruction and recycling.  |
| Novel mechanism for invasion of EV71 virus demonstrated Posted: 18 Jul 2014 08:04 AM PDT A novel mechanism for EV71 entry mediated by its receptor SCARB2 has been reported by scientists. These findings make a significant conceptual advance in the understanding of non-enveloped virus entry, to which EV71 belongs. Enterovirus 71 (EV71) is the major causative agent of hand, foot and mouth disease in the Asia-Pacific region. Unlike other enteroviruses, EV71 can cause severe aseptic meningitis, encephalitis, myocarditis and acute flaccid paralysis, thus leading to significant fatality rates.  |
| A 10-year endeavor: NASA's Aura and climate change Posted: 18 Jul 2014 07:27 AM PDT Celebrating its 10th anniversary this week, NASA's Aura satellite and its four onboard instruments measure some of the climate agents in the atmosphere, including greenhouse gases, clouds and dust particles. These global datasets provide clues that help scientists understand how Earth's climate has varied and how it will continue to change.  |
| Ten-year endeavor: NASA's Aura tracks pollutants Posted: 18 Jul 2014 07:25 AM PDT NASA's Aura satellite, celebrating its 10th anniversary on July 15, has provided vital data about the cause, concentrations and impact of major air pollutants. With instruments providing key measurements of various gases -- including two built and managed by NASA's Jet Propulsion Laboratory: the Tropospheric Emission Spectrometer (TES) and Microwave Limb Sounder (MLS) -- Aura gives a comprehensive view of one of the most important parts of Earth -- the atmosphere.  |
| Four new species of tuco-tucos identified from Bolivia Posted: 18 Jul 2014 06:57 AM PDT Four new species of Ctenomys, a genus of gopher-like mammals found throughout much of South America, have been identified by researchers. The burrowing rodents are commonly called tuco-tucos. The burrowing rodents range from 7 to 12 inches long and weigh less than a pound. They demonstrate the broad range of biological diversity in the lowlands and central valleys of Bolivia, where all four new species were found, a researcher notes.  |
| Big data used to guide conservation efforts Posted: 18 Jul 2014 06:57 AM PDT Genetic studies have given us detailed information about the evolutionary relationships embodied in the Tree of Life, while newly digitized museum collections contain a wealth of information about species distribution. To date, however, these big data collections have not been applied to conservation efforts. Now researchers have created a model taking both distribution and relationships into account to identify lineages that need preservation, in particular rare endemics.  |
| Measuring the number of protein molecules inside cells Posted: 18 Jul 2014 06:56 AM PDT The identification of the genes and proteins involved in a biological process, as well as the way they interact, are essential for the understanding of that process. However, often little is known about the dimensions of molecular biological structures. Knowing how many molecules make up a structure and are required for its function are essential for our understanding of biological mechanisms, yet poses a difficult challenge. Now, in a breakthrough study, researchers were able to measure the amount of protein molecules in living human cells required to form the centromere.  |
| Revealed: The mystery behind starling flocks Posted: 18 Jul 2014 06:56 AM PDT The mystery behind the movements of flocking starlings could be explained by the areas of light and dark created as they fly, new research suggests. The research found that flocking starlings aim to maintain an optimum density at which they can gather data on their surroundings. This occurs when they can see light through the flock at many angles, a state known as marginal opacity. The subsequent pattern of light and dark, formed as the birds attempt to achieve the necessary density, is what provides vital information to individual birds within the flock.  |
| Nature's strongest glue comes unstuck Posted: 18 Jul 2014 06:54 AM PDT Over a 150 years since it was first described by Darwin, scientists are finally uncovering the secrets behind the super strength of barnacle glue. Still far better than anything we have been able to develop synthetically, barnacle glue -- or cement -- sticks to any surface, under any conditions. But exactly how this superglue of superglues works has remained a mystery -- until now.  |
| Catastrophic debris avalanches: A second volcanic hazard Posted: 18 Jul 2014 06:54 AM PDT Volcanic hazards aren't limited to eruptions. Debris avalanche landslides can also cause a great deal of damage and loss of life. Stratovolcanoes, with their steep, conical shapes made up of lava and unconsolidated mixed materials, can reach a critical point of instability when they overgrow their flanks. This leads to partial collapse, and the product of this slope failure is a large-scale, rapid mass movement known as a catastrophic landslide or debris avalanche.  |
| Politically driven legislation targeting dangerous dogs has had little impact Posted: 17 Jul 2014 06:22 PM PDT UK legislation that targets 'dangerous dogs' has not been shown to reduce dog bites and policies should be based on evidence and risk assessment, suggests a new article. Risk assessment for human violence has proved to be accurate and reliable and the author says this "might be a practical preventative measure to reduce injury from dog bite" along with medical and veterinary professionals "familiarizing themselves with evidence based resources."  |
| Choosing cheese: Research identifies microbial communities in cheese Posted: 17 Jul 2014 03:05 PM PDT After studying 137 varieties of cheese collected in 10 different countries, researchers have been able to identify three general types of microbial communities that live on cheese, opening the door to using each as a 'model' community for the study of whether and how various microbes and fungi compete or cooperate as they form communities, what molecules may be involved in the process and what mechanisms may be involved.  |
| Fish oil may benefit alcohol abusers Posted: 17 Jul 2014 03:02 PM PDT Omega-3 fish oil might help protect against alcohol-related neurodamage and the risk of eventual dementia, according to a study. Many human studies have shown that long-term alcohol abuse causes brain damage and increases the risk of dementia. The new study found that in brain cells exposed to high levels of alcohol, a fish oil compound protected against inflammation and neuronal cell death.  |
| Preventing foodborne illness naturally: with cinnamon Posted: 17 Jul 2014 06:51 AM PDT Cinnamomum cassia oil was shown to be effective as a natural antibacterial agent against several strains of Shiga toxin-producing Escherichia coli, known to the US Centers for Disease Control and Prevention as 'non-O157 STEC'. The study results add to a body of knowledge that will help improve food safety and reduce or eliminate cases of food poisoning and related deaths.  |
| Worm study provides hope for deadly disease of the brain Posted: 16 Jul 2014 09:34 AM PDT An untreatable and deadly neurodegenerative disease has been modelled and treated in worms by researchers, suggesting a cure could be found for humans. For the first time scientists have replicated the disease in nematode worms and successfully treated it with a drug called resveratrol. "As we face an increasingly aging population, having treatments for these conditions becomes ever more critical. Studying how these diseases work in a simple organism which is easy and cheap to breed, can speed up the process of developing effective drugs," a researcher said.  |
