Physics news

	Diphoton bump at LHC leads to generation of hundreds of theoretical papers (Phys.org)—Last year, two teams working at the LHC reported that they had found proton-to-proton collisions that had led to the creation of more photon pairs (with energies of approximately 750 GeV) than was expected, leading to theories that the evidence might be pointing to a new particle than no one has theorized. This discovery led to a plethora of teams creating papers seeking to be the first to explain this seeming anomaly—so many papers have been submitted to journals for publication that editors have had to pick and choose which to publish. One example is Robert Garisto with Physical Review Letters, who has published an editorial describing the onrush and the decision to publish just four papers in their latest edition, which the editorial team believes is representative of the four main ideas.
	One step closer to finding the highly exotic and elusive 'spin nematic' phase Neutron scattering at ANSTO has contributed to building evidence for the existence of a highly exotic and elusive state of matter, known as a magnetic 'spin nematic' phase in a natural mineral called linarite.
	2+1 is not always 3: In the microworld unity is not always strength In the microscopic world, as long as there are only two particles, things are relatively simple. When other particles are introduced, however, the situation soon becomes more complicated. Imagine there are two people pushing a broken-down car: The total force is the sum of their forces. Similarly, if there are three people, the total force would be the sum of the force of these three people, and so on. Now imagine a colloid, a solid particle of a few thousandths of a millimeter, immersed in fluid. Imagine also that just ahead, there is a similar particle. If there are "critical" thermal fluctuations in the fluid that separates them, the two particles will either repel or attract each other without even touching, a phenomenon caused by the fluctuations alone. In other words, an interaction force called the "critical Casimir" force emerges, as if the particles were connected by an invisible spring. Obtain critical fluctuations requi! res only one of many transparent liquids composed of a mixture of two fluids that gradually separate like oil and water when their temperature is raised.
	Pressing the simplest element to exotic quantum states The hydrogens—hydrogen and its isotopes—are the simplest and most abundant of the elements in the universe. Conceptually hydrogen, with a single proton and electron is the simplest atomic system in the periodic table of the elements, yet has exceptionally complex behavior due to its light mass and interactions with other hydrogen atoms.
	The atom without properties The microscopic world is governed by the rules of quantum mechanics, where the properties of a particle can be completely undetermined and yet strongly correlated with those of other particles. Physicists from the University of Basel have observed these so-called Bell correlations for the first time between hundreds of atoms. Their findings are published in the scientific journal Science.
	Numerical simulations shed new light on early universe Innovative multidisciplinary research in nuclear and particle physics and cosmology has led to the development of a new, more accurate computer code to study the early universe. The code simulates conditions during the first few minutes of cosmological evolution to model the role of neutrinos, nuclei and other particles in shaping the early universe.
	Antimatter unveils the secrets of liquid crystals Liquid crystals combine such contradictory features as the chaos of liquid molecules, and the ordering characteristics of crystals. Thanks to an innovative application of antimatter, it has been demonstrated at the Institute of Nuclear Physics of the Polish Academy of Sciences in Krakow that the structures formed by certain molecules of liquid crystals must in fact be different than previously thought.
	Laser light exposes the properties of materials used in batteries and electronics Creating the batteries or electronics of the future requires understanding materials that are just a few atoms thick and that change their fundamental physical properties in fractions of a second. Cutting-edge facilities at SLAC National Accelerator Laboratory and Stanford University have allowed researchers like Aaron Lindenberg to visualize properties of these nanoscale materials at ultrafast time scales.

Earth news

	Unhealthy ozone days could increase by more than a week in coming decades If emission rates continue unchecked, regions of the United States could experience between three and nine additional days per year of unhealthy ozone levels by 2050, according to a new study from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) published in Geophysical Research Letters.
	Volcanoes tied to shifts in Earth's climate over millions of years A new study in the April 22 edition of Science reveals that volcanic activity associated with the plate-tectonic movement of continents may be responsible for climatic shifts from hot to cold over tens and hundreds of millions of years throughout much of Earth's history.
	Current measurement methods may be vastly underestimating the amount of plastic in the oceans Plastics are all around us. They are found in containers and packing materials, children's toys, medical devices and electronics.
	The Arctic is facing a decline in sea ice that might equal the negative record of 2012 Sea ice physicists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), are anticipating that the sea ice cover in the Arctic Ocean this summer may shrink to the record low of 2012. The scientists made this projection after evaluating current satellite data about the thickness of the ice cover. The data show that the arctic sea ice was already extraordinarily thin in the summer of 2015. Comparably little new ice formed during the past winter. Today Dr Marcel Nicolaus, expert on sea ice, has presented these findings at a press conference during the annual General Assembly of the European Geosciences Union in Vienna.
	1.5 C vs 2 C global warming: New study shows why half a degree matters European researchers have found substantially different climate change impacts for a global warming of 1.5°C and 2°C by 2100, the two temperature limits included in the Paris climate agreement. The additional 0.5°C would mean a 10-cm-higher global sea-level rise by 2100, longer heat waves, and would result in virtually all tropical coral reefs being at risk. The research is published today (21 April) in Earth System Dynamics, an open access journal of the European Geosciences Union, and is presented at the EGU General Assembly.
	Mild weather since 1970s worrying for the American view on climate threat In a chronicle published in Nature, Swedish researcher Joacim Rocklöv at Umeå University reasons around the findings of a new research study showing that American's scepticism towards climate issues are partly due to the improved weather. The cognitive dissonance taking place between self-experienced changes in weather and the long-term threat can explain why people have a hard time making climate conscious decisions.
More productive U.S. national forests and grasslands could yield less water in a future climate A warmer climate may lead to higher growth and productivity on U.S. national forests and grasslands, but university and U.S. Forest Service researchers say this could reduce quantities of freshwater flowing from most of these lands, even with increases in precipitation. Results were published today in Scientific Reports.
	Preparations for a US west coast tsunami look to the past and future After the 2011 Tohoku earthquake and devastating tsunami in Japan, states such as California, Oregon, Washington and Alaska are looking to both the past and the future to prepare for a tsunami on the U.S. Pacific coastline.
	Half-a-degree makes a huge difference A jump in global temperature of two degrees Celsius would double the severity of crop failures, water shortages and heatwaves in many regions compared to a rise of 1.5 C, according to a study released Thursday.
	South American floods kill 12, force mass evacuations Severe storms and flooding across South America's "southern cone" have killed at least 12 people and forced thousands to evacuate, with more bad weather on the way.
	Island states come to UN ready to move on climate deal With their very existence under threat from climate change, the world's island states come to the United Nations on Friday not only to sign the Paris climate deal but to be first in line to make sure it goes into force.
	Interactive composting, recycling station shows savings in real time "You just composted 2.31 ounces," the screen reads. "If everyone on campus composted this amount today, UW would save $1,181.00."
	"Zero deforestation" champion creates new risks for Indonesia's forests and peatlands A new study by twelve international and Indonesian NGOs shows that in spite of its high-profile commitment to "zero deforestation", Asia Pulp & Paper (APP) is building one of the world's largest pulp mills in the Indonesian province of South Sumatra without a sustainable wood supply.
	NASA's GPM looks at Texas heavy rainfall The Global Precipitation Measurement or GPM mission core satellite provides next-generation observations of rain and snow worldwide every three hours.

Biology news

	Bird genomes contain 'fossils' of parasites that now infect humans In rare instances, DNA is known to have jumped from one species to another. If a parasite's DNA jumps to its host's genome, it could leave evidence of that parasitic interaction that could be found millions of years later—a DNA 'fossil' of sorts. An international research team led from Uppsala University has discovered a new type of so-called transposable element that occurred in the genomes of certain birds and nematodes.
	Cpf1: CRISPR-enzyme scissors cutting both RNA and DNA Only a few years after its discovery, it is difficult to conceive of genetics without the CRISPR-Cas9 enzyme scissors, which allow for a very simple, versatile and reliable modification of DNA of various organisms.

	Evolution in action detected in Darwin's finches The most characteristic feature of Darwin's finches is the diversification of beak morphology that has allowed these species to expand their utilization of food resources in the Galápagos archipelago. A team of scientists from Uppsala University and Princeton University has now identified a gene that explains variation in beak size within and among species. The gene contributed to a rapid shift in beak size of the medium ground finch following a severe drought. The study is published in Science.
Wapiti whistles sound like Ringwraith shrieks For a majestic animal that looks equally at home as the monarch of the glen or astride the great American Plains, the wapiti's call is somewhat disconcerting. Sounding more like the shrieking cries of a Lord of the Rings Ringwraith, their haunting high-pitched screeches can carry great distances. 'Larger animals tend to have deeper resonances and lower voices', says David Reby, from the University of Sussex, UK, explaining how the pitch of an animal's voice tends to be a good indicator of its size: animals from larger species have larger larynges that vibrate at a lower pitch than animals from smaller species. However, the wapiti's extraordinary bugle calls would be more at home coming from the body of an animal the fraction of the size of these impressive red deer. The paradox had puzzled scientists for decades, but when Megan Wyman returned from a trip recording deer bellows in New Zealand, Reby knew that they might have a chanc! e to finally lay the mystery to rest. The team publishes their discovery that wapitis whistle while simultaneously roaring through their vocal chords to produce their distinctive calls in Journal of Experimental Biology.
	Crayfish may help restore dirty streams, study finds While macroinvertebrates are a tasty food source for crayfish, a new study reveals a surprising finding: When crayfish were present in in-stream experimental enclosures, macroinvertebrate density was higher, not lower.
Australian furry friend gets 'toad-smart' to survive Scientists are training an endangered furry marsupial—Australia's beloved quoll—to avoid eating toxic toads that have devastated predator populations in a novel attempt to save native fauna.

Virus therapy to attack superbugs VIRUSES specifically designed to battle superbugs are being trialled in a South Australian hospital.
	Aerial surveys can spot boll weevil hideouts U.S. cotton growers spent $20 million to monitor and control boll weevils in 2015, and the pest continues to infest cotton in the Lower Rio Grande Valley, the southernmost cotton-producing region in the United States. To prevent the insects from taking refuge in cotton plants, growers there mow down their plants after harvest and may spray plant stalks with herbicides.
	Clever fish avoid being caught in angling hotspots Keen anglers heading out this long weekend should seek a quiet spot or prepare themselves for disappointment, new University of Queensland research shows.

	Mechanism behind plant withering clarified A research team from Kobe University have reproduced the reaction in which harmful reactive oxygen species are created during plant photosynthesis, and clarified a mechanism behind plant withering. This discovery could help to ensure stable food supplies by cultivating plants that can withstand environmental stresses such as global warming. The findings were published on March 2 in the online version of Plant Physiology.
	Binding to produce flowers The LEAFY protein, a transcription factor responsible for flower development, is able to assemble itself in small chains made up of several proteins. This mechanism allows it to bind to and activate regions of the genome that are inaccessible to a single protein. These results were obtained by scientists in the Laboratoire de Physiologie Cellulaire Végétale (CNRS/Inra/CEA/Université Grenoble Alpes) and the Institut de Biologie Structurale (CNRS/CEA/Université Grenoble Alpes), working in collaboration with their international partners. Published on 21 April 2016 in Nature Communications, they open the way to new research opportunities regarding the regulation of gene expression.
	Active substances from plants—bioreactor modules share production work Plants produce a number of substances that can be used to treat cancer, Alzheimer's or Parkinson's disease. Frequently, however, metabolic pathways to obtain the target substance are so complex that its biotechnological production is hardly effective and very expensive. Scientists of KIT now combine their expertise with the technical know-how of Phyton Biotech GmbH, the biggest producer of pharmaceutical ingredients with plant cells. With the help of a microfluidic bioreactor consisting of coupled modules, the scientists technically reproduce complex plant tissue to produce active substances against cancer or Alzheimer's disease more effectively and at lower costs.
	Virtual opponents reveal fighting strategies of male jumping spiders Jumping spiders are known for their excellent vision and the elaborate body language they display when encountering other members of their species. These attributes may enable them to visually size up a potential opponent and decide whether to step away from a possible fight even before it starts. However, in live fights, jumping spiders may have limited opportunity to show this skill. This is according to Rowan McGinley and Phillip Taylor of Macquarie University in Sydney, Australia. Their findings are published in Springer's journal Behavioral Ecology and Sociobiology.
	Island foxes may be 'least variable' of all wild animals In comparison to their relatives on the mainland, the Channel Island foxes living on six of California's Channel Islands are dwarves, at two-thirds the size. The island foxes most likely evolved from gray foxes brought to the northern islands by humans over 7,000 years ago. Some think island foxes may have been partially domesticated by Native Americans. Like many island species, they have little fear of humans.
The importance of resting phases in B cell development Everyone preparing for the London Marathon likely knows that to perform their best during the event, they need to rest up now. Research at the Babraham Institute just published in the journal Science describes a new mechanism through which B cells ensure that they rest up between intensive developmental events.
Better data needed to stop sixth mass extinction To prevent a new mass extinction of the world's animal and plant life, we need to understand the threats to biodiversity, where they occur and how quickly change is happening. For this to happen, we need reliable and accessible data. A new study published in Science today reveals those data are largely missing. We are lacking key information on important threats to biodiversity such as invasive species, logging, bush meat harvesting, and illegal wildlife trade.
	New research shows how different strains of bed bugs resist insecticides There are many reasons why bed bugs have made a comeback in recent decades, and their resistance to commonly used insecticides is one of the most widely accepted explanations.
Only US grizzly recovery coordinator retiring after 35 years The nation's first and only grizzly bear recovery coordinator is stepping down after 35 years, saying the threatened species has recovered enough for him to retire.
	Outwitting poachers with artificial intelligence A century ago, more than 60,000 tigers roamed the wild. Today, the worldwide estimate has dwindled to around 3,200. Poaching is one of the main drivers of this precipitous drop. Whether killed for skins, medicine or trophy hunting, humans have pushed tigers to near-extinction. The same applies to other large animal species like elephants and rhinoceros that play unique and crucial roles in the ecosystems where they live.

	Biological control of weeds via their own aromas Plant experts in the Netherlands can still become enthusiastic about a special variety of broomrape. Farmers in southern countries, however, are less impressed because broomrape and its 'sister' striga are considered a harmful weed in these regions. Research in the Laboratory of Plant Physiology of Wageningen University shows how useful insects that can control this weed may lend a helping hand in the future, namely via the plant's own aromatic substances. "You can also use a mixture of aromatic substances to distinguish various varieties of parasitic plants," says Harro Bouwmeester, professor in plant physiology.
	Scientists call on public to look and listen out for cuckoos Devon residents are being asked to record cuckoos seen or heard in the county as part of an ongoing conservation project that has received 2,000 reports of the species by the general public in the last two years.
	Sentinel-1 counts fish Images from the Sentinel-1A satellite are being used to monitor aquaculture in the Mediterranean, in another example of the mission's contribution to food security, as fisheries become the main source of seafood.
	The cell copying machine: How daughters look like their mothers Tiny structures in our cells, called centrioles, control both cell division and motility. The number of these structures is highly monitored, with deviations causing infertility, microcephaly and accelerating cancer. But how do mother cells know they provide the right number of centrioles to their daughters? They do it by copying those structures only once, so that each daughter inherits one of the copies. A research team, from Instituto Gulbenkian de Ciencia (IGC; Portugal), led by Monica Bettencourt-Dias uncovered the mechanism by which the mother copies only once before it distributes it to the two daughters. This study is now published in the latest issue of the scientific journal Current Biology.
	Water color and phytoplankton growth in the Gulf of Maine are changing Dr. William "Barney" Balch's team at Bigelow Laboratory for Ocean Sciences has been sampling the waters of the Gulf of Maine regularly over the same transect for the last 18 years as part of a NASA-funded study. Working with scientists from the U.S. Geological Survey, Dr. Thomas Huntington and Dr. George Aiken, Balch reported in a recent paper an overall reduction in productivity in the Gulf of Maine.

	Asleep somewhere new, one brain hemisphere keeps watch People who go to bed wary of potential danger sometimes pledge to sleep "with one eye open." A new Brown University study finds that isn't too far off. On the first night in a new place, the research suggests, one brain hemisphere remains more awake than the other during deep sleep, apparently in a state of readiness for trouble.
Confused cells lead to genetic disorders like heart problems, premature aging It has been disorienting to the scientific and medical community as to why different subtle changes in a protein-coding gene causes many different genetic disorders in different patients—including premature aging, nerve problems, heart problems and muscle problems. no other gene works like this. According to a new study, co-authored by Binghamton University faculty Eric Hoffman, it has to do with cell "commitment."
	Infectious outbreaks must be combatted strategically, experts argue New funding is not enough to guarantee success against emerging infectious diseases around the world. Rather, good governance, a long-term technology investment strategy and strong product management skills are essential, say a Dartmouth College researcher and her co-author.

	How a macaque's brain knows it's swinging Any organism with a brain needs to make decisions about how it's going to navigate through three-dimensional spaces. That's why animals have evolved sensory organs in the ears to detect if they're rotating or moving in a straight line. But how does an animal perceive curved motion, as in turning a corner? One explanation, published April 21 in Cell Reports, from researchers looking at macaques, is that curved motion is detected when sensory neurons in the brain receiving converging information about linear and rotational movement are activated.
	Can we hypercharge vaccines? Tapping a chemical we already make could enhance T-cell production Researchers at Boston Children's Hospital report that a fatty chemical naturally found in damaged tissues can induce an unexpected kind of immune response, causing immune cells to go into a "hyperactive" state that is highly effective at rallying infection-fighting T-cells. The findings, published online by Science on April 21, could enhance vaccines and make them much more effective.

	Study suggests immune response to flu causes death in older people, not the virus A new Yale-led study suggests that death from influenza virus in older people may be primarily caused by a damaging immune response to flu and not by the virus itself. The insight could lead to novel strategies for combating flu in the most vulnerable patients, said the researchers.
	Mechanics of a heartbeat are controlled by molecular strut in heart muscle cells On top of the meaning and mystery that humans heap on the heart, it is first and foremost, a muscle. And one that beats about once a second for a person's entire life, with no rest. Given its vital importance, it's ironic researchers have only recently made direct observations of its subcellular parts in motion.
Teen moms and infant sleep: Mother doesn't always know best Sudden unexpected infant death (SUID), which includes sudden infant death syndrome (SIDS), is the leading cause of death in infants 1 month to 1 year of age in the United States. Although the reason is unknown, maternal age less than 20 years is associated with an increased risk of SIDS. In a new study scheduled for publication in The Journal of Pediatrics, researchers found that although teenage mothers know the recommendations in regards to safe sleeping practices, many deliberately do not follow those recommendations.

Mindful eating helps to lose weight—and keep it off Losing weight is difficult, and keeping it off can be even harder. Many people regain the weight because typical weight loss diets involve drastic, unsustainable changes. Alternatively, learning to eat "mindfully" can fundamentally shift our relationship with food for long-term weight loss maintenance.
	Positive, humane and practical—a new paradigm for understanding autism For more than four decades, Barry Prizant has worked as a clinical scholar, researcher and consultant to persons with autism spectrum disorders (ASD). Through his 2015 book "Uniquely Human: A Different Way of Seeing Autism," and a new musical theater and arts program at Brown, Prizant continues to impact the way ASD is understood and treated.
Recycling an anti-hypertensive agent to fight brain tumors Treatments available for glioblastoma—malignant brain tumors—have little effect. An international collaboration led by the Laboratoire Neurosciences Paris-Seine (CNRS/ INSERM/UPMC) tested active ingredients from existing medications and eventually identified one compound of interest, prazosin, on these tumors. Not only did it seem to be effective in this type of cancer, but it also acted on a signaling pathway that is common with other cancers. These promising findings are available online (advance publication) in EMBO Molecular Medicine.
	Sci-fi still influences how society thinks about genes—it's time we caught up We used to think that our fate was in the stars. Now we know in large measure, our fate is in our genes.
New insights in how blood vessels increase their size A new study from the group of Holger Gerhardt (VIB/KU Leuven/Cancer Research UK/ MDC/BIH Berlin) in collaboration with Katie Bentley's Lab (Cancer Research UK/BIDMC-Harvard Medical School) addresses a long standing question in the wider field of developmental biology and tissue patterning in general, and in the vascular biology field in particular: 'What are the fundamental mechanisms controlling size and shape of tubular organ systems'. Whereas the most obvious way to grow a tube in size would be to add more building blocks (by proliferating cells) to enlarge its circumference, or to increase the size of the building blocks (the cells, hypertrophy), an alternative way would be to rearrange existing building blocks. Benedetta Ubezio, Raquel Blanco and colleagues under the direction of Holger Gerhardt and Katie Bentley now show that cell rearrangement is the way blood vessels switch from making new branches to increasing the size o! f a branch. The researchers also found that this switch is triggered by synchronization of cells under the influence of increasing levels of the growth factor VEGFA.
	A plant-based polyphenol for improving wound healing discovered A research group led by Osaka University found a plant-based polyphenol, promotes the migration of Mesenchymal Stem Cells (MSCs) in blood circulation and accumulates them in damaged tissues to improve wound healing.

	Opinion: Pure, white and deadly—is the sugar-driven diabetes epidemic unstoppable? John Yudkin, British nutritionist and 1972 author of the highly-controversial book "Pure, White and Deadly", and who sounded the alarm on sugar and poor health when I was a postdoc at Purdue University and then a staff scientist at the National Institute of Medical Research in London, was ridiculed and his reputation ruined by the highly politicised and now, scientifically flawed anti-cholesterol anti-saturated fat bandwagon. Today, in a tragic real-life opera currently being played out in the arena of the World Health Organization (WHO), sugar has replaced fat as the villain, and Yudkin is the hero.
Interrogation computers work—if you believe they are human controlled Avatars can potentially make interrogations more efficient. However, a study by psychologists based at the Institute for Innovation and Governance Studies, a University of Twente research institute, shows that they are only effective if the subjects under interrogation believe that the avatar is under human control. The study was published in Frontiers in Psychology, an open access journal.

	Powerful genetic regulator identified as risk factor for schizophrenia By turning skin cells into brain neurons, researchers at the Icahn School of Medicine at Mount Sinai have identified that certain tiny molecules aiding in gene expression, known as microRNAs (miRNAs), are under-expressed in the brains of the 14 schizophrenia patients they studied. Their findings, published online today in the journal Cell Reports, show that one of these molecules, a miRNA known as miR-9, is a risk factor that controls the activity of hundreds of genes.
Researchers identify new mechanism to target 'undruggable' cancer gene RAS genes are mutated in more than 30 percent of human cancers and represent one of the most sought-after cancer targets for drug developers. However, this goal has been elusive because of the absence of any drug-binding pockets in the mutant RAS protein. A new study published in the April 20 issue of the journal Cell by researchers at the Icahn School of Medicine at Mount Sinai led by E. Premkumar Reddy, PhD, has identified a new mechanism for targeting this important cancer gene.

	HIV infection prematurely ages humans by an average of five years Thanks to combination antiretroviral therapy, many people with HIV can be expected to live decades after being infected. Yet doctors have observed that these patients often show signs of premature aging. Now a study published April 21 in Molecular Cell has applied a highly accurate biomarker to measure just how much HIV infection ages people at the biological level—an average of almost 5 years.
	Increasing cases of anaphylaxis among children Anaphylaxis, known to be a sudden and potentially life-threatening allergic reaction, seems to be increasing among children, according to a new study led by a team at the Research Institute of the McGill University Health Centre (RI-MUHC). The findings, published this week in the Journal of Allergy and Clinical Immunology (JACI), reveal that the percentage of emergency department (ED) visits due to anaphylaxis doubled over a four-year period based on data collected from the Montreal Children's Hospital of the MUHC (MCH-MUHC).
	How immunity to RSV develops in childhood but deteriorates in adults The leading infectious cause of severe respiratory disease in infants, respiratory syncytial virus (RSV), is also a major cause of respiratory illness in the elderly. Approved vaccines do not yet exist, and despite the development of partial immunity following infection during childhood, individuals remain susceptible to RSV reinfection life-long. A comprehensive characterization of the antibody-response to RSV published on April 21st in PLOS Pathogens advances our understanding of the human immune response against RSV and has implications for vaccine design.
Young adult survivors of childhood cancer report feeling middle-aged Do survivors of childhood cancer return to normal health as they grow up? According to new research from Dana-Farber/Boston Children's Cancer and Blood Disorders Center and Harvard T.H. Chan School of Public Health, overall health-related quality of life in young adult survivors of childhood cancer resembles that of middle-aged adults. In a study published today in the Journal of the National Cancer Institute, the investigators show that childhood cancer survivors who are 18 to 29 years old report overall health-related quality of life similar to that reported by adults in the general population who are in their 40s.

New genetic risk factors for myopia discovered Myopia, also known as short-sightedness or near-sightedness, is the most common disorder affecting the eyesight and it is on the increase. The causes are both genetic and environmental. The Consortium for Refractive Error and Myopia (CREAM) has now made important progress towards understanding the mechanisms behind the development of the condition. This international group of researchers includes scientists involved in the Gutenberg Health Study of the University Medical Center of Johannes Gutenberg University Mainz (JGU). The team has uncovered nine new genetic risk factors which work together with education-related behavior as the most important environmental factor causing myopia to generate the disorder. The results of the study "Genome-wide joint meta-analyses of genetic main effects and interaction with education level identify additional loci for refractive error: The CREAM Consortium" have recently been published in the sc! ientific journal Nature Communications.
Study links neighborhood greenness to reduction in chronic diseases A new study of a quarter-million Miami-Dade County Medicare beneficiaries showed that higher levels of neighborhood greenness, including trees, grass and other vegetation, were linked to a significant reduction in the rate of chronic illnesses, particularly in low-to-middle income neighborhoods. Led by researchers at the University of Miami Department of Public Health Sciences at the Miller School of Medicine, and the School of Architecture, the study showed that higher greenness was linked to significantly lower rates of diabetes, hypertension and high cholesterol, as well as fewer chronic health conditions.
Immune cells in organ cavities play essential role in fast tissue repair While scientists have known for many years that there are cells living in the cavities surrounding various organs such as the heart, lung and liver, their function has remained unknown.

New study shows electronic health records often capture incomplete mental health data Complementary sources of data can be used to paint a more complete picture of a patient's health trajectory than a single source. Significant recent investment in Electronic Health Records (EHRs) took place on the assumption of improved patient safety, research capacity, and cost savings. However, most of these health systems and health records are fragmented and do not share patient information. While fragmentation and incomplete clinical data in EHRs are recognized problems, almost no published data estimate their extent. This study compares information available in a typical EHR with data from insurance claims, focusing on diagnoses, visits, and hospital care for depression and bipolar disorder.
Researchers find moderate vascular risk in southwest native population In a newly published, pilot study in the journal Ethnicity & Disease, researchers report a relatively low prevalence of vascular risk among participants of the Southwest Heart Mind Study, especially among those treated for hypertension and hyperlipidemia despite overweight and obesity.

	DNA proves mammoths mated beyond species boundaries Several species of mammoth are thought to have roamed across the North American continent. A new study in the open-access journal Frontiers in Ecology and Evolution, provides DNA evidence to show that these mammoths, which should only mate within their species boundaries, were in fact likely to be interbreeding.
	Fossil teeth suggest that seeds saved bird ancestors from extinction When the dinosaurs became extinct, plenty of small bird-like dinosaurs disappeared along with giants like Tyrannosaurus and Triceratops. Why only some of them survived to become modern-day birds remains a mystery. Now, researchers reporting April 21 in Current Biology suggest that abrupt ecological changes following a meteor impact may have been more detrimental to carnivorous bird-like dinosaurs, and early modern birds with toothless beaks were able to survive on seeds when other food sources declined.
	Leg-wing cooperation in baby birds, dinosaurs is key transition in origin of flight New research based on high-resolution x-ray movies reveals that despite having extremely underdeveloped muscles and wings, young birds acquire a mature flight stroke early in their development, initially relying heavily on their legs and wings to work in tandem to power the strenuous movement. The new study, published today in the journal PLOS ONE, is important for understanding the development of flight in modern birds and reconstructing its origins in extinct dinosaurs.

	Girls more anxious about mathematics, STEM subjects compared to boys Global studies have shown that women are underrepresented in some science, technology, engineering and mathematics (STEM) subjects and fields. Even in countries with higher gender equality, sex differences in math and technical scores persist.

Often called "mathematics anxiety," scientists believe that several factors other than math performance are resulting in higher mathematics anxiety in girls compared to boys.
