Female doctors who suffer domestic abuse can feel unable to get help due to perceptions that it "should not happen to a doctor" and a judgemental culture in medical settings, a new study suggests. Victim-survivors who work as doctors often do not feel able to talk about abuse confidentially and fear the consequences of reporting it. Researchers from the University of Southampton interviewed twenty-one female doctors who had previously left an abusive relationship about their experience of domestic abuse, barriers they faced when seeking help, and the impact on their work. The findings have been published in the British Journal of General Practice. Dr Emily Donovan, who led the study from the University of Southampton's Primary Care Research Centre said: "Domestic ...

Education is considered one of the most critical personal capital investments. But formal educational attainment doesn't necessarily pay off in job satisfaction, according to new research from the University of Notre Dame. In fact, there is almost no relationship between the two, according to "Does Educational Attainment Promote Job Satisfaction? The Bittersweet Trade-offs Between Job Resources, Demands and Stress," forthcoming in the Journal of Applied Psychology from Brittany Solomon (Hall), assistant professor of management, and Dean Shepherd, the Ray and Milann Siegfried ...

Researchers at Cincinnati Children's Hospital Medical Center have developed a new framework for different factors influencing how a child's brain is "wired" to learn to read before kindergarten. This may help pediatric providers identify risks when the brain is most responsive to experiences and interventions. This "eco-bio-developmental" model of emergent literacy, described in the journal JAMA Pediatrics, reinforces the potential of early screening, prevention, and intervention during pediatric clinic visits in early childhood. This kind of model is advocated by the American Academy ...

Remote monitoring using airborne devices such as drones or satellites could revolutionise the effectiveness of nature-based solutions (NBS) that protect communities from devastating natural hazards such as floods, storms and landslides, say climate change experts from the University of Surrey. Grey structural measures (a collective term for engineering projects that use concrete and steel) like floodgates, dams, dikes and sea walls are still the most common methods to guard against natural hazards. However, these 'grey measures' are expensive and lack the long-term flexibility and sustainability needed to help communities manage their growing population and address the planet's ongoing struggle against urbanisation ...

Scientists have discovered that tracking malaria as it develops in humans is a powerful way to detect how the malaria parasite causes a range of infection outcomes in its host. The study, found some remarkable differences in the way individuals respond to malaria and raises fresh questions in the quest to understand and defeat the deadly disease. Malaria, caused by the parasite - Plasmodium falciparum - is a huge threat to adults and children in the developing world. Each year, around half a million people die from the disease and another 250 million are infected. Malaria parasites are spread to humans through the bites of infected mosquitoes. The outcomes that follow a malaria infection can vary from no symptoms to life-threatening ...

A team of scientists has been using DESY's X-ray source PETRA III to analyse the structural changes that take place in an egg when you cook it. The work reveals how the proteins in the white of a chicken egg unfold and cross-link with each other to form a solid structure when heated. Their innovative method can be of interest to the food industry as well as to the broad field of research surrounding protein analysis. The cooperation of two groups, headed by Frank Schreiber from the University of Tübingen and Christian Gutt from the University of Siegen, with scientists at DESY and European XFEL reports the research in two articles in the journal Physical Review Letters. Eggs are among the most versatile food ingredients. They can take the form of a gel or ...

Adding the nutrient selenium to diets protects against obesity and provides metabolic benefits to mice, according to a study published today in eLife. The results could lead to interventions that reproduce many of the anti-aging effects associated with dietary restriction while also allowing people to eat as normal. Several types of diet have been shown to increase healthspan - that is, the period of healthy lifespan. One of the proven methods of increasing healthspan in many organisms, including non-human mammals, is to restrict dietary intake of an amino acid ...

Humans are creating or exacerbating the environmental conditions that could lead to further pandemics, new University of Sydney research finds. Modelling from the Sydney School of Veterinary Science suggests pressure on ecosystems, climate change and economic development are key factors associated with the diversification of pathogens (disease-causing agents, like viruses and bacteria). This has potential to lead to disease outbreaks. The research, by Dr Balbir B Singh, Professor Michael Ward, and Associate Professor Navneet Dhand, is published in the international journal, Transboundary and Emerging Diseases. They found a greater diversity ...

Superconductivity is known to be easily destroyed by strong magnetic fields. NIMS, Osaka University and Hokkaido University have jointly discovered that a superconductor with atomic-scale thickness can retain its superconductivity even when a strong magnetic field is applied to it. The team has also identified a new mechanism behind this phenomenon. These results may facilitate the development of superconducting materials resistant to magnetic fields and topological superconductors composed of superconducting and magnetic materials. Superconductivity has been used in various technologies, such as magnetic resonance imaging (MRI) and ...

This breakthrough will accelerate the development of new tire materials to provide super wear resistance, greater environmental friendliness, and longer service life. It will also aid significantly in the advancement of smart tires. SRI initially developed 4D-CT as part of the ADVANCED 4D NANO DESIGN, a new materials development technology unveiled in 2015 that enables highly accurate analysis and simulation of the rubber's internal structure from the micro to nanoscale. This analysis ultimately ...

An evolutionary mystery that had eluded molecular biologists for decades may never have been solved if it weren't for the COVID-19 pandemic. "Being stuck at home was a blessing in disguise, as there were no experiments that could be done. We just had our computers and lots of time," says Professor Paul Curmi, a structural biologist and molecular biophysicist with UNSW Sydney. Prof. Curmi is referring to research published this month in Nature Communications that details the painstaking unravelling and reconstruction of a key protein in a single-celled, photosynthetic organism called a cryptophyte, a type of algae that evolved over a billion years ago. Up until now, how cryptophytes acquired the proteins ...

About 61% of Americans have had at least one Adverse Childhood Experience (ACE), experts' formal term for a traumatic childhood event. ACEs--which may include abuse, neglect and severe household dysfunction--often lead to psychological and social struggles that reach into adulthood, making ACEs a major public health challenge. But the long-term consequences of ACEs are just beginning to be understood in detail. To fill in the picture, two recent BYU studies analyzed how ACEs shape adolescents' delinquent behaviors as well as fathers' parenting approaches. ACEs ...

An international survey that included 600 smokers in the UK has found that cessation messaging focused on easing the burden on our health system is most effective in encouraging people to quit. The research, which was conducted in April-May 2020, randomly assigned participants to view one of four quit smoking messages, two of which explicitly referenced health implications and COVID-19, one referred more vaguely to risk of chest infection, and one highlighted financial motivations for quitting. "We wanted to explore the effectiveness of smoking cessation messaging at a time when health systems the world over are beleaguered, and all our ...

Replacing regular common salt consumed by hypertensive patients in rural areas with a salt substitute can have a significant impact in terms of lowering their blood pressure, a new study by The George Institute for Global Health has revealed. Researchers found that substituting a small part of the sodium in salt with potassium without altering the taste led to a substantial reduction in systolic blood pressure in these patients, supporting salt substitution as an effective, low-cost intervention for lowering blood pressure in rural India. The study entitled "Effects of reduced-sodium added-potassium salt substitute on blood pressure in rural Indian hypertensive patients: a randomized, double-blind, controlled trial" provides the first-of-its-kind evidence from ...

In a new study published in the Cell Research, Chen-Yu Zhang's group at Nanjing University reports "In vivo self-assembled small RNA is the new generation of RNAi therapeutics". The development of RNAi therapy has undergone two major stages, direct injection of synthetic siRNAs and delivery with artificial vehicles; both have not realized the full therapeutic potential of RNAi in clinic. In this study, Chen-Yu Zhang's group reprogram host liver with genetic circuits to direct the synthesis and self-assembly of siRNAs into secretory exosomes. In vivo assembled siRNAs are systematically distributed to multiple tissues or targeted to specific tissues (e.g., brain), inducing potent target gene silencing in these tissues. The therapeutic value of this strategy is demonstrated ...

A team of researchers from Graz University of Technology, Know-Center GmbH, Johannes Kepler University Linz, University of Innsbruck, Austria and University of Utrecht, the Netherlands, compared how accurate algorithm-generated music recommendations were for mainstream and non-mainstream music listeners. They used a dataset containing the listening histories of 4,148 users of the music streaming platform Last.fm who either listened to mostly non-mainstream music or mostly mainstream music (2,074 users in each group). Based on the artists music users' listened to most frequently, the authors used a computational model to predict how likely music users were to like the music recommended ...

Failure to comply with international exposure recommendations for air pollution, noise, heat and access to green space is associated with more than 1,000 deaths per year in Barcelona and more than 900 in Madrid, accounting for 7% and 3% of overall premature mortality, respectively. This is the conclusion of a new study by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation. This study is the first to estimate premature mortality impacts and the distribution by socioeconomic status of multiple environmental exposures related to urban planning and transport in the two cities. Today, more than half of the ...

Tsukuba, Japan - Although the heart beats autonomously, its function can be regulated by the brain in response to, for instance, stressful events. In a new study, researchers from the University of Tsukuba discovered a novel mechanism by which a specific part of the brain, the lateral habenula (LHb), regulates the cardiovascular system. The cardiovascular system, specifically the heart and blood vessels, have a certain autonomy that allows them to function independently from the brain. In order for the individual to adapt to new, potentially threatening situations, the brain does have some regulatory power over the cardiovascular ...

Primary sclerosing cholangitis (PSC) is a rare, chronic, inflammatory disease of the bile ducts and is difficult to treat, since its causes have not yet been adequately researched. Using RNA sequencing, an international research consortium led by Michael Trauner, Head of MedUni Vienna's Division of Gastroenterology and Hepatology (Department of Medicine III), has now succeeded in identifying a new prognostic factor for PSC from liver biopsies. This is so-called cellular ER stress. ER stress is the name given to a complex cellular response to stress caused by the build-up of misfolded proteins in the endoplasmic reticulum (ER). PSC is a rare disease with a poor prognosis and can lead to cirrhosis ...

In modern basic life science research as well as in drug discovery, recording and analyzing the images of cells over time using 3D microscopy has become extremely important. Once the images have been recorded, the same cell in different images at different time points has to be accurately identified ("cell tracking") because the living cells captured in the images are in motion. However, tracking many cells automatically in 3D microscope videos has been considerably difficult. In the Kimura laboratory at the Nagoya City University, Dr. Chentao Wen and colleagues developed the 1st AI-based software called 3DeeCellTracker that can run on a desktop PC and automatically track cells in 3D microscope videos. ...

Researchers have mapped the distribution of SARS-CoV-2, the virus that causes COVID-19, in deceased patients with the disease, and shed new light on how viral load relates to tissue damage. Their study of 11 autopsy cases, published today in eLife, may contribute to our understanding of how COVID-19 develops in the body following infection. More than 24 million SARS-CoV-2 infections have been reported to date, and the number of deaths attributed to COVID-19 has exceeded 828,000 worldwide. COVID-19 occurs with varying degrees of severity. While most patients have mild symptoms, some experience more severe symptoms and may need to be hospitalised. A minority of those in hospital may enter a critical condition, with respiratory failure, blood vessel complications, or multiple organ ...

Recent studies indicate a link between children's cardiorespiratory fitness and their school performance: the more athletic they are, the better their marks in the main subjects - French and mathematics. Similarly, cardiorespiratory fitness is known to benefit cognitive abilities, such as memory and attention. But what is the real influence of such fitness on school results? To answer this question, researchers at the University of Geneva (UNIGE), Switzerland tested pupils from eight Geneva schools. Their results, published in the journal Medicine & Science in Sport & Exercise, show that there is an indirect link with cardiorespiratory fitness influencing ...

Alloying, the process of mixing metals in different ratios, has been a known method for creating materials with enhanced properties for thousands of years, ever since copper and tin were combined to form the much harder bronze. Despite its age, this technology remains at the heart of modern electronics and optics industries. Semiconducting alloys, for instance, can be engineered to optimize a device's electrical, mechanical and optical properties. Alloys of oxygen with group III elements, such as aluminum, gallium, and indium, are important semiconductor materials with vast applications ...

It's no secret. Colorado's forests have had a tough time in recent years. While natural disturbances such as insect outbreaks and wildfires occurred historically and maintained forest health over time, multiple, simultaneous insect disturbances in the greater region over the past two decades have led to rapid changes in the state's forests. A bird's eye view can reveal much about these changes. Annual aerial surveys conducted by the Colorado State Forest Service and USDA Forest Service have provided yearly snapshots for the state. New collaborative research led by Colorado State University and the University of Wisconsin-Madison now supplements this understanding with even greater spatial detail. The ...

A growing number of young people are identifying as part of the LGBTQ+ community, and many are challenging binaries in gender and sexual identity to reflect a broader spectrum of experience beyond man or woman and gay or straight. But not everyone is participating equally in these diverse forms of expression, according to new research from the University of California, Santa Cruz. Psychology Professor Phillip Hammack's latest paper, published in the Journal of Adolescent Research, is shedding light on the social factors that can either hinder or support expression of diversity in sexual and gender identity ...
