Hip dysplasia is a developmental disorder common in most dog breeds, and its onset is affected by both hereditary and environmental factors. Prior studies have identified dozens of genetic loci associated with hip dysplasia in various breeds. The relevance of the loci to disease susceptibility remains an open question. The previously identified loci were reinvestigated at the University of Helsinki, Finland, using a large independent cohort of 1,600 dogs representing ten breeds. The individual genetic variants at the target loci were determined from blood samples. The standardized ...

While most adults over 50 understand that overuse of antibiotics is a problem, and say they're cautious about taking the drugs, a sizable minority have used antibiotics for something other than their original purpose, and appear to think the drugs could help treat colds, which are caused by viruses not bacteria. These findings, contained in a new paper in Infection Control and Hospital Epidemiology, come from a national poll of people between the ages of 50 and 80 carried out as part of the National Poll on Healthy Aging. The authors, from the University of ...

Cracow, 18 February 2021 Creation of matter in an interaction of two photons belongs to a class of very rare phenomena. From the data of the ATLAS experiment at the LHC, collected with the new AFP proton detectors at the highest energies available to-date, a more accurate - and more interesting - picture of the phenomena occurring during photon collisions is emerging. If you point a glowing flashlight towards another one, you do not expect any spectacular phenomena. The photons emitted by both flashlights simply pass by each other. However, in certain collisions involving high-energy protons the situation is different. The ...

Air pollution levels may have exceeded air quality standards during the development of some Marcellus Shale natural gas wells in Pennsylvania, potentially impacting more than 36,000 people in one year alone during the drilling boom, according to Penn State scientists. "The construction and drilling of these wells are a relatively short-term thing, and assessment of the impact on air quality is something that often falls through the cracks," said Jeremy Gernand, associate professor of industrial health and safety at Penn State. "But there are thousands and thousands of wells drilled depending on the year, and we wanted to see what the impact would be if we added it all up." More than 20,000 unconventional Marcellus Shale gas wells have been drilled ...

The distribution of vegetation is routinely used to classify climate regions worldwide, yet whether these regions are relevant to other organisms is unknown. Umeå researchers have established climate regions based on vertebrate species' distributions in a new study published in eLife. They found that while high-energy climate regions are similar across vertebrate and plant groups, there are large differences in temperate and cold climates. Climate determines how life organises across the world. Understanding which climatic conditions drive important changes in ecosystems is crucial to understanding and predicting how life functions and evolves. Human well-being critically ...

Having trouble coping with COVID? Go take a hike. Literally. Researchers have long been aware of the positive impact of a connection with nature on psychological health and, according to a new study published in the journal Personality and Individual Differences, the pandemic hasn't decreased the power of nature to improve mental well-being. "Thinking about the natural world in an interconnected and harmonious way corresponds to improved psychological health, no matter where you are," says Brian W. Haas, the lead author of the new study and an associate professor in the Behavioral and Brain Sciences Program at the University of Georgia. Haas and his collaborators - Fumiko Hoeft, a professor of psychological sciences at UConn ...

Almost 100 years ago, a revolutionary discovery was made in the field of physics: microscopic matter exhibits wave properties. Over the decades, more and more precise experiments have been used to measure the wave properties of electrons in particular. These experiments were mostly based on spectroscopic analysis of the hydrogen atom and they enabled verifying the accuracy of the quantum theory of the electron. For heavy elementary particles - for example protons - and nuclides (atomic nuclei), it is difficult to measure their wave properties accurately. In principle, however, these properties can be seen everywhere. In molecules, the wave properties ...

An international team of researchers has developed a framework for assessing brand reputation in real time and over time, and built a tool for implementing the framework. In a proof of concept demonstration looking at leading brands, the researchers found that changes in a given brand's stock shares reflected real-time changes in the brand's reputation. "We've developed something we call the Brand Reputation Tracker that mines social media text on Twitter and uses 11 different measures to give us an in-depth understanding of how users feel about individual brands," says Bill Rand, co-lead author of the paper and an associate professor of marketing in North Carolina State University's Poole College of Management. The Brand Reputation Tracker ...

Evidence that a sense of our physical selves can develop even without the sense of touch has been uncovered in a new study by researchers in the UK and the United States. The research shows that if someone loses their sense of touch and 'proprioception' - their sense of body position - as an adult, they may learn compensatory skills using visual cues and conscious thought, or reasoning, to move their bodies. Someone who has never had a sense of touch or proprioception, however, can find faster, unconscious ways of processing visual cues to move and orient themselves. A team at the University of Birmingham collaborated with researchers at Bournemouth University and the University of Chicago on the study, ...

In the late 1980s and 1990s, researchers at ETH Zurich discovered the first indications that the amount of sunlight reaching the Earth's surface had been steadily declining since the 1950s. The phenomenon was known as "global dimming". However, a reversal in this trend became discernible in the late 1980s. The atmosphere brightened again at many locations and surface solar radiation increased. "In previous studies, we showed that the amount of sunlight that reaches the Earth's surface is not constant over many decades but instead varies substantially - a phenomenon known as global dimming and brightening," ...

Researchers from Rutgers Cancer Institute of New Jersey, the state's only National Cancer Institute-designated Comprehensive Cancer Center, evaluated the frequency of SARS-CoV-2, the virus that causes COVID-19, on various environmental surfaces in outpatient and inpatient hematology/oncology settings located within Rutgers Cancer Institute and Robert Wood Johnson University Hospital, an RWJBarnabas Health facility. The study revealed extremely low detection of SARS-CoV-2 on environmental surfaces across multiple outpatient and inpatient oncology areas, including an active COVID-19 floor. Andrew M. Evens, DO, MSc, FACP, associate director for clinical services and director of the Lymphoma Program at Rutgers Cancer Institute and medical director of the oncology service ...

Annapolis, MD; February 17, 2021--When the invasive spotted lanternfly arrived in the United States in 2014, it was immediately recognized for the threat it posed to native plants and crops. A community of researchers and experts in science, agriculture, and government sprang into action to respond, improving our chances for containing the pest and curbing its potential for damage. While the effort continues, a new collection curated by the Entomological Society of America's family of journals showcases the growing body of research that is helping us understand the spotted lanternfly's biology and how to contain it. The collection features 25 articles published ...

When there is a choice, wolves in Mongolia prefer to feed on wild animals rather than grazing livestock. This is the discovery by a research team from the University of Göttingen and the Senckenberg Museum Görlitz. Previous studies had shown that the diet of wolves in inland Central Asia consists mainly of grazing livestock, which could lead to increasing conflict between nomadic livestock herders and wild predatory animals like wolves. The study has been published in the journal Mammalian Biology. Around three million people live in Mongolia, making it the most sparsely populated country in the world. In addition, there are more than 40 million grazing animals. These animals are not just a source of food but also the ...

By 2030 only EV's will be in production, meaning manufacturers are racing to create a high-energy battery that's affordable and charges efficiently, but conventional battery cathodes cannot reach the targets of 500Wh/Kg Lithium-excess cathodes offer the ability to reach 500Wh/Kg but unlocking their full capacity means understanding how they can store charge at high voltages. A new X-ray study lead by WMG, University of Warwick has resolved how the metals and oxygen facilitate the charge storage at high voltages. High energy storage batteries for EVs need high capacity battery cathodes. New lithium-excess magnesium-rich cathodes are expected to replace existing nickel-rich cathodes but understanding how the magnesium and oxygen accommodate charge storage at high ...

As investors set their sights on the mineral resources of the deep seabed, the International Seabed Authority (ISA) is developing regulations that will govern their future exploration and possible exploitation. A new IASS Policy Brief, published in cooperation with the Federal Environment Agency (UBA), presents three recommendations to ensure that future deep seabed mining would be to the common benefit all humankind, as required by international law. The ecosystems of the deep ocean are complex and provide a wide range of benefits to humankind. Oceans soak up carbon dioxide and act as a natural buffer to global warming in addition to regulating the climate and serving as an important ...

CHAMPAIGN, Ill. -- Researchers report that 4-6-year-old children who walk further than their peers during a timed test - a method used to estimate cardiorespiratory health - also do better on cognitive tests and other measures of brain function. Published in the Journal of Clinical Medicine, the study suggests that the link between cardiorespiratory fitness and cognitive health is evident even earlier in life than previously appreciated. Most studies of the link between fitness and brain health focus on adults or preadolescent or adolescent children, said doctoral student Shelby Keye, who led the new research with Naiman Khan, a professor of kinesiology and ...

CHAMPAIGN, Ill. -- Workers with science, technology, engineering and math backgrounds are typically in high demand - but the demand isn't so overwhelming that a "skills gap" exists in the labor market for information technology help desk workers, one of the largest computer occupations in the U.S., says new research from a University of Illinois Urbana-Champaign expert who studies labor economics and work issues. The incidence of prolonged hiring difficulties for STEM workers is modest, with only 11%-15% of IT help desks in the U.S. showing vacancy patterns that might be consistent with persistent hiring frictions, said Andrew Weaver, a professor ...

The mechanism that keeps arterial blood pressure stable in black and white tegu lizards (Salvator merianae) even as their body temperature varies substantially is more efficient at lower than higher external temperatures, contrary to what has always been believed, and vascular regulation plays a key role in pressure adjustments, according to an article published in PLOS ONE by researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil. The research was supported by FAPESP. The findings pave the way for more investigation of the physiology of ectothermic animals, which rely on external environmental factors to regulate body temperature, and of novel applications for the method used in ...

A new study concluding out of Lusaka, Zambia last summer has found that as many as 19% (almost 1 in 5) of recently-deceased people tested positive for COVID-19. A new Boston University School of Public Health (BUSPH) study in Lusaka, Zambia's capital, challenges the common belief that Africa somehow "dodged" the COVID-19 pandemic. The findings indicate that low numbers of reported infections and deaths across Africa may simply be from lack of testing, with the coronavirus taking a terrible but invisible toll on the continent. Published in The BMJ, the study found that at least ...

Neutralizing antibodies develop within two weeks of a SARS-CoV-2 infection, but their durability and intensity can vary by individual, prompting concerns about the prospects of long-lasting immunity and efficacy of COVID-19 vaccines. In a PLOS ONE paper, published online February 11, 2021, researchers at University of California San Diego School of Medicine report that individual immune response to SARS-CoV-2, the virus that causes COVID-19, may be limited by the major histocompatibility complex or MHC, a set of variable genes that code for cell surface proteins essential for the adaptive immune system. Specifically, ...

Dreams take us to what feels like a different reality. They also happen while we're fast asleep. So, you might not expect that a person in the midst of a vivid dream would be able to perceive questions and provide answers to them. But a new study reported in the journal Current Biology on February 18 shows that, in fact, they can. "We found that individuals in REM sleep can interact with an experimenter and engage in real-time communication," said senior author Ken Paller (@kap101) of Northwestern University. "We also showed that dreamers are capable of comprehending questions, engaging in working-memory operations, and producing answers. ...

Dogs may be able to recognize their own body as an obstacle and also understand the consequences of their own actions, according to a study involving 32 pet dogs published in Scientific Reports. Previous research has shown that dogs have complex cognitive capabilities, such as empathy and social learning, but whether they also show any form of self-awareness was not clear. Péter Pongrácz and Rita Lenkei tested dogs in a 'body as an obstacle' task, during which the dogs had to pick up and give a toy to their owner, whilst standing on a small mat to which the toy was attached. In order to lift the toy, the dogs had to leave the mat. The authors found that dogs left the mat more frequently and sooner when the ...

The simplest of organic molecules have a much more complex relationship with oxygen than previously thought. Researchers from KAUST and their international collaborators have shown that alkanes participate extensively in autoxidation reactions with oxygen molecules1. The discovery, which overturns current chemical wisdom, has implications for air quality prediction and efficient fuel combustion in engines. Autoxidation is a chemical process in which oxygen molecules rapidly and sequentially add to organic molecules in a radical chain reaction. The process is critical for ...

New research published in Nature Food warns that heat stress in animals caused by rising temperatures and humidity will occur more frequently and for longer periods, impacting milk and meat productivity for dairy cattle, beef cattle, sheep, goat, pigs and poultry across East Africa. Analysis of historical data from 1981-2010 shows that livestock have already been progressively subjected to heat stress conditions. According to projections, this is set to worsen significantly, with severe implications for livestock unable to cope with the extra heat. Authors warn that 4-19% of current meat and milk production occurs in areas where dangerous heat stress conditions are likely to increase in frequency from 2071-2100. If climate conditions ...

The gut microbiome is an integral component of the body, but its importance in the human aging process is unclear. ISB researchers and their collaborators have identified distinct signatures in the gut microbiome that are associated with either healthy or unhealthy aging trajectories, which in turn predict survival in a population of older individuals. The work is set to be published in the journal Nature Metabolism. (Once the embargo lifts, you can access the paper here.) The research team analyzed gut microbiome, phenotypic and clinical data from over 9,000 people - between the ages of 18 and 101 years old - across three independent cohorts. The team focused, ...
