Nanotechnology news

	Using solid-state materials with gold nanoantennas for more durable solar cells Hokkaido University scientists are testing the development of solar cells made of solid materials to improve their ability to function under harsh environmental conditions.
	The next generation of carbon monoxide nanosensors The detection of carbon monoxide (CO) in the air is a vital issue, as CO is a poisonous gas and an environmental pollutant. CO typically derives from the incomplete combustion of carbon-based fuels, such as cooking gas and gasoline; it has no odour, taste, or colour and hence it is difficult to detect. Scientists have been investigating sensors that can determine CO concentration, and a team from the Okinawa Institute of Science and Technology Graduate University (OIST), in tandem with the University of Toulouse, has found an innovative method to build such sensors.
	Harnessing solar and wind energy in one device could power the 'Internet of Things' The "Internet of Things" could make cities "smarter" by connecting an extensive network of tiny communications devices to make life more efficient. But all these machines will require a lot of energy. Rather than adding to the global reliance on fossil fuels to power the network, researchers say they have a new solution. Their report on a single device that harvests wind and solar energy appears in the journal ACS Nano.

	Drugs and dung a bad mix for climate: study Scientists have discovered a potential threat to Earth's climate lurking in a dark and smelly place: the dung of cattle treated with antibiotics, a study said Wednesday.
	Current atmospheric models underestimate the dirtiness of Arctic air Black carbon aerosols—particles of carbon that rise into the atmosphere when biomass, agricultural waste, and fossil fuels are burned in an incomplete way—are important for understanding climate change, as they absorb sunlight, leading to higher atmospheric temperatures, and can also coat Arctic snow with a darker layer, reducing its reflectivity and leading to increased melting. Unfortunately, current simulation models, which combine global climate models with aerosol transport models, consistently underestimate the amount of these aerosols in the Arctic compared to actual measurements during the spring and winter seasons, making it difficult to accurately assess the impact of these substances on the climate.
	New cloud formation discovery may lessen warming forecast A new discovery about how clouds form may scale back some of the more dire predictions about temperature increases caused by man-made global warming.
	Antarctic wildlife at risk from human derived E. coli Human sewage disposal in Antarctica presents a risk of introducing non-native bacterial species, specifically E. coli, into endemic Antarctic wildlife, potentially affecting its diversity and evolution, a new research project led by Macquarie University has found.
	Target coal or carbon? Researchers are analyzing coal and energy caps as carbon policy instruments for China In China, coal is king. The source of about 70 percent of the nation's energy supply, it has long been the engine of the Chinese economy. But the reign of coal, which has the highest carbon content of all fossil fuels, has resulted in unintended consequences, from local air pollution to global climate change. While China is currently moving ahead with a national carbon market covering large emitters, an ongoing question remains whether and how the country might also directly restrict the use of coal to tackle the triple threat of air pollution, climate change, and energy insecurity. One option under discussion involves imposing limits on the use of coal or on all fossil fuels (coal, oil, and natural gas) at the national or regional levels.
	Australia's volcanic history is a lot more recent than you think Australia is an old and stable continent with not many geological risks such as major earthquakes and volcanic eruptions. At least that is what most people think.
	Effects of Saharan dust transport on climate change under study Studying the processes of transport and deposition of dust from the Sahara desert and African fires is the main objective of scientific expedition JC134 of the Royal Research Ship James Cook. The purpose of the study is to determine the importance of dust transport in regulating the planet's climate and marine ecosystems This is the last transatlantic cruise conducted under the framework of the Dust Traffic project led by Jan Berend Stuut and funded by the European Research Council (ERC).
	Program measures natural background radiation levels around the world Members of a high school science club gather in the school's chemistry lab for a lunchtime meeting to learn about local, natural sources of radiation as a nearby wall-mounted sensor box with glowing LED lights collects live radiation data and feeds it to a website.
New water-quality data on impact of corn, soybeans on nitrate in Iowa streams As Iowa farmers have planted more acres of corn to meet the demand driven by the corn-based ethanol industry, many models predicted that nitrate concentrations in Iowa streams would increase accordingly. However, recent IIHR research based on water monitoring and published in the Journal of Soil and Water Conservation casts doubt on these predictions.
	Many unknown chemicals in the Baltic Sea The researchers examined data from research and monitoring reports from the years 2000-2012, to see what chemicals have been analysed in Baltic Sea fish.
	Downed World War II aircraft missing for 72 years located in Pacific Islands An American aircraft, a TBM-1C Avenger, missing since July 1944 was recently located in the waters surrounding the Pacific Island nation of Palau by Project RECOVER—a collaborative effort to combine the most advanced oceanographic technology with advanced archival research methods to locate aircraft and associated Americans missing in action (MIA) since World War II.
	Spring comes sooner to urban heat islands, with potential consequences for wildlife With spring now fully sprung, a new study by University of Wisconsin-Madison researchers shows that buds burst earlier in dense urban areas than in their suburban and rural surroundings. This may be music to urban gardeners' ears, but that tune could be alarming to some native and migratory birds and bugs.
	Following tricky triclosan: Antibacterial product flows through streams, crops Most U.S. homes are full of familiar household products with an ingredient that fights bacteria: triclosan. Triclosan seems to be everywhere. When we wash our hands, brush our teeth, or do our laundry, we are likely putting triclosan into our water sources.

Chemistry news

	Making some of the world's most durable materials corrosion-resistant Borides are among the hardest and most heat-resistant substances on the planet, but their Achilles' Heel, like so many materials', is that they oxidize at high temperatures. Oxidation is the chemical reaction commonly known as corrosion or rusting—it can signal the end for a material's structural integrity. But researchers from Drexel University, Linkoping University in Sweden and Imperial College London have produced an aluminum-layered boride whose unique behavior at high temperatures keeps it one step ahead of nature's slow march toward high- temperature chemical degradation.
	Scientists capture the elusive structure of essential digestive enzyme Using a powerful combination of techniques from biophysics to mathematics, researchers have revealed new insights into the mechanism of a liver enzyme that is critical for human health. The enzyme, phenylalanine hydroxylase, turns the essential amino acid phenylalanine - found in eggs, beef and many other foods and as an additive in diet soda —into tyrosine, a precursor for multiple important neurotransmitters.
	Hybrid cancer drug could be resistance-resistant A team of cancer researchers led by scientists at UC San Francisco and Memorial Sloan Kettering Cancer Center demonstrated in human cells and mouse models that a first-of-its-kind hybrid drug can outsmart drug-resistant cancers.

	A 100-million-year partnership on the brink of extinction A relationship that has lasted for 100 million years is at serious risk of ending, due to the effects of environmental and climate change. A species of spiny crayfish native to Australia and the tiny flatworms that depend on them are both at risk of extinction, according to researchers from the UK and Australia.
	Female meerkats compete to outgrow their sisters Meerkats live in groups of up to 50 individuals, yet a single dominant pair will almost completely monopolise reproduction, while subordinates help to raise offspring through feeding and babysitting. Since only a small minority of individuals ever get to be dominants, competition for the breeding role is intense in both sexes and females are unusually aggressive to each other.
	Study exposes possible reason for 'drop out' fish in aquaculture salmon farms (Phys.org)—A team of researchers from Norway, Denmark and the Netherlands has found evidence that might explain "drop out" fish in salmon and other fish farms. In their paper published in the journal Royal Society Open Science, the team describes their studies of salmon brain chemistry of specimens taken from fish farms and what their findings might mean for improving fishery results.
	Why fruit fly sperm are giant In the animal kingdom, sperm usually are considerably smaller than eggs, which means that males can produce far more of them. Large numbers of tiny sperm can increase the probability of successful fertilization, especially when females mate with several males. This is because the competition among sperm from different males to fertilize the few eggs increases as sperm become more abundant. This sperm competition spurs sexual selection after mating, favoring the best sperm in the female reproductive tract.
	Is aging inevitable? Not necessarily for sea urchins Sea urchins are remarkable organisms. They can quickly regrow damaged spines and feet. Some species also live to extraordinary old ages and—even more remarkably—do so with no signs of poor health, such as a decline in regenerative capacity or an increase in age-related mortality. These ocean Methuselahs even reproduce as if they were still youngsters.

Medicine & Health news

	Human amyloid-beta acts as natural antibiotic in the brains of animal models A new study from Massachusetts General Hospital (MGH) investigators provides additional evidence that amyloid-beta protein - which is deposited in the form of beta-amyloid plaques in the brains of patients with Alzheimer's disease - is a normal part of the innate immune system, the body's first-line defense against infection. Their study published in Science Translational Medicine finds that expression of human amyloid-beta (A-beta) was protective against potentially lethal infections in mice, in roundworms and in cultured human brain cells. The findings may lead to potential new therapeutic strategies and suggest limitations to therapies designed to eliminate amyloid plaques from patient's brains.
	Out of tune: Mismatch of vascular and neural responses suggests limits of fMRI In an article published online ahead of print on May 25, 2016 in Nature, investigators at the Medical University of South Carolina (MUSC) report that, during sensory stimulation, increases in blood flow are not precisely "tuned" to local neural activity, challenging the long-held view that vascular and local neural responses are tightly coupled.

Children's social and academic functioning is impeded when their families move more often America is a mobile society, with most children and their families moving once or more during childhood. Moving can bring new opportunities if families relocate to safer, more comfortable homes, or to communities with better schools. However, previous research has found that more frequent residential moves can lead to stress and disrupt children's routines, with negative repercussions for healthy development. Now a new study has found that each additional residential move that children experience is associated with a corresponding decline in reading and math scores, as well as less positive social skills and higher rates of emotional and behavioral problems. The study compared children who move frequently with those who don't move or who move less frequently.
Parents' discrimination experiences linked to lower well-being among Mexican-American teens Mexican-Americans are one of the largest ethnic minority groups in the United States, and Mexican-American adolescents who experience ethnic discrimination are more likely to report lower self-esteem and more emotional problems. A new study has found that the teens' psychological adjustment also suffers when their parents face ethnic discrimination. Parents' discussions with their teens about culture, race and ethnicity, and discrimination can play a role in their teens' psychological adjustment, but the content matters.
As early as first grade, children with severe obesity are more likely to be ostracized Childhood obesity has almost quadrupled among 6- to 11-year-olds since 1980. Today, approximately one in 20 children in the United States is severely obese and this public health threat costs the U.S. government billions of dollars annually. A new study has found that as early as first grade, severely obese children are more likely to be withdrawn and show signs of depression. They are also less liked by their peers, and more often picked on, teased, and made fun of than their classmates of healthy weights.

	Fighting addiction through the gut-brain axis "We are what we eat." This piece of folk knowledge is true in more ways than one. In fact, it is well known that food, through action on the enteric system, has direct effects on the brain. The mechanisms underlying this exchange are no longer a mystery since a large body of scientific literature highlights the functional crosstalk between the periphery and the brain. In particular, the so-called gut-brain axis consists of bidirectional communication between the brain and the enteric system, linking the emotional and cognitive centers of the brain with peripheral intestinal functions (and vice versa). Insights into the gut-brain crosstalk have revealed an extremely fascinating communication system that is thought to be involved in many routine functions and systems within the healthy body, as well as in many diseases.
	The science of doping in sports Doping in sports continues making headlines as the U.S. Justice Department investigates state-sponsored doping by dozens of Russian athletes in the Olympic Games. The International Olympic Committee defines doping as "the deliberate or inadvertent use by an athlete of a substance or method banned by the IOC." Those substances and methods include performance-enhancing drugs and procedures that can have a variety of effects, including increasing muscle mass, enhancing recovery, blocking pain, upping the oxygen capacity of the blood to boost muscle performance and endurance, and even preventing detection of doping itself.
Physician anesthesiologists oppose VA rule replacing physicians with nurses in anesthesia The American Society of Anesthesiologists (ASA) urges Americans to protect our nation's Veterans by opposing a U.S. Department of Veterans Affairs (VA) proposed policy that removes physician anesthesiologists from surgery and replaces them with nurses, lowering the standard of care and jeopardizing Veterans' lives.
	Mechanism for inhibiting bacterial invasion of colonic epithelia elucidated A group of researchers at Osaka University elucidated how a gene named Ly6/Plaur domain containing 8 (Lypd8) inhibits bacterial invasion of colonic epithelia, regulating intestinal inflammation.

Lung function may affect vocal health for women Teaching is an occupation with a high risk of developing vocal problems—teachers have more than twice the voice problems than people in other professions, as the voice is the major tool in classroom instruction and is often used for long periods of time and in noisy environments. Additionally, females face a significantly higher risk than men of developing long-term vocal problems. Therefore female teachers, the predominate population of teaching workforce, face a dual risk for developing prolonged voice problem. In a collaboration between Harvard Medical School and the Gould Voice Research Center, researchers displayed that the cost of teachers' voice injuries to the U.S. economy is estimated at US$2.5 billion per year. As a result, many scientists have worked on finding the physiological causes to help teachers prevent and treat voice problems.
