LAWRENCE -- Recent incidents of racial discrimination and violence against Asians and Asian-Americans in the United States have prompted critical discussions about how to talk about such biases with younger age groups. New research from the University of Kansas shows using critical race media literacy, or examining how race and gender are addressed in popular culture, can be an effective way to discuss those topics and engage students. KU researchers published a study in which they observed an American teacher using critical race media literacy to discuss racism and sexism in superhero movies in English as a foreign language classes in a South Korean high school. They argued that successful implementation ...

Through his role on the U.S. Preventive Services Task Force, UVA Health's Li Li, MD, PhD, MPH, has helped develop new lung cancer screening guidelines that expand screenings to more high-risk patients. The new guidelines are focused on Americans at higher risk because of their history of smoking, which is the leading cause of lung cancer. There are two significant changes in the new guidelines. For those who are still smoking or quit less than 15 years ago, a yearly screening using a low-dose computed tomography (CT) scan is now recommended: beginning at age 50, instead of age 55. for anyone who has smoked 20 pack-years in their lifetime, instead of 30 pack-years. A pack-year equals smoking a pack of cigarettes a day for a year. The ...

Physicists from the University of Sussex have developed an extremely thin, large-area semiconductor surface source of terahertz, composed of just a few atomic layers and compatible with existing electronic platforms. Terahertz sources emit brief light pulses oscillating at 'trillion of times per second'. At this scale, they are too fast to be handled by standard electronics, and, until recently, too slow to be handled by optical technologies. This has great significance for the evolution of ultra-fast communication devices above the 300GHz limit - such as that required for 6G mobile phone technology - something that is still fundamentally beyond the limit of current electronics. Researchers ...

People are adept at discerning most of the different emotions that underlie screams, such as anger, frustration, pain, surprise or fear, finds a new study by psychologists at Emory University. Screams of happiness, however, are more often interpreted as fear when heard without any additional context, the results show. PeerJ published the research, the first in-depth look at the human ability to decode the range of emotions tied to the acoustic cues of screams. "To a large extent, the study participants were quite good at judging the original context of a scream, simply by listening to it through headphones without any visual cues," says Harold Gouzoules, Emory professor of psychology and senior author of the study. ...

WHAT: When variants of SARS-CoV-2 (the virus that causes COVID-19) emerged in late 2020, concern arose that they might elude protective immune responses generated by prior infection or vaccination, potentially making re-infection more likely or vaccination less effective. To investigate this possibility, researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and colleagues analyzed blood cell samples from 30 people who had contracted and recovered from COVID-19 prior to the emergence of virus variants. They found that one key player in the immune response to SARS-CoV-2--the CD8+ T cell--remained active against the virus. The research team was led by NIAID's Andrew Redd, Ph.D., and included ...

Indigenous traditions often place land at the centre of their cultures. However, with more than half of Canada's Indigenous population now living in urban areas and Indigenous communities struggling to overcome legacies of colonialism defined by assimilation and land theft, that connection is getting frayed. Elizabeth Fast, an associate professor of applied human sciences in the Faculty of Arts and Science, wanted to help Indigenous youth reconnect with their cultures in safe and accessible ways. Along with a youth advisory group composed of Indigenous youth (some of whom are also students), she has been organizing a series of land-based learning retreats ...

BOSTON - (March 25, 2021) - A mechanism has been identified that explains how physical exercise in pregnancy confers metabolic health benefits in offspring. According to researchers, the key lies with a protein called SOD3, vitamin D and adequate exercise, with the outcomes possibly forming the first steps to designing rational diet and exercise programs to use during pregnancy and particularly when mothers may also be overweight or obese. The study, which was led by authors from the Joslin Diabetes Center at the Harvard Medical School and colleagues from Japan, the US, Canada and Denmark, has been published online by Cell Metabolism. "We've known for a while that risks for obesity and type 2 diabetes can originate in the critical ...

In a new study published in Conservation Science and Practice, researchers at the University of Maryland (UMD) partnered with Indonesian experts to explore the motivations and challenges of women pursuing a career in conservation sciences in Indonesia. Given that Indonesia is one of the most biodiverse countries on the planet but is simultaneously experiencing extreme rates of deforestation, it is an important target country for the conservation of global biodiversity. Conservation work remains male-dominated in Indonesia, especially fieldwork, so gaining a better understanding of the cultural norms and barriers in place for Indonesian women aspiring to a career in conservation represents an important step in supporting women ...

Researchers from Newcastle University, UK, working with colleagues at King Mongkut's University of Technology Thonburi (KMUTT) in Thailand and the Institute of Urban Environment of the Chinese Academy of Sciences, analysed samples of water and sediment taken from aquaculture ponds and nearby canals at five locations in central Thailand's coastal region. The research, which was part-funded by an institutional links grant awarded by the Newton Fund via the British Council, and which has been published in the Journal of Hazardous Materials, found that the highest prevalence of antimicrobial resistance (AMR) genes was in water ...

Gas hydrates are a solid compound of gases and water that have an ice-like structure at low temperatures and high pressures. Compounds of methane and water, so-called methane hydrates, are found especially at many ocean margins - also in the Black Sea. In addition to a possible use as an energy source, methane hydrate deposits are being investigated for their stability, as they can dissolve with changes in temperature and pressure. In addition to releases of methane, this can also have an impact on submarine slope stability. During a six-week expedition with the German research vessel METEOR in autumn 2017, a team from MARUM and GEOMAR investigated a methane hydrate deposit in the deep-sea fan of the Danube in the western Black Sea. During ...

Most businesses were ill-prepared to deal with the pandemic and muddled though the challenges stemming from it, according to a report published today. Resilience reimagined: a practical guide for organisations was produced by Cranfield University, in partnership with the National Preparedness Commission (NPC) and Deloitte. The report presents insights from business leaders from a range of sectors and makes seven recommendations for organisations on how to become more resilient, drawing on lessons from past 12 months. Cranfield University's Professor David Denyer and Mike Sutliff conducted in-depth interviews and four focus groups with more than 50 C-suite level people (boards, senior executives, policymakers, and resilience directors) from FTSE 100 companies, ...

As social media platforms like Instagram, Snapchat, TikTok and others continue to grow in popularity, adolescents are spending more of their time online navigating a complex virtual world. New research suggests that these increased hours spent online may be associated with cyberbullying behaviors. According to a study by the University of Georgia, higher social media addiction scores, more hours spent online, and identifying as male significantly predicted cyberbullying perpetration in adolescents. "There are some people who engage in cyberbullying online because of the anonymity and the fact that there's no retaliation," said Amanda Giordano, principal investigator of the study and associate professor in the UGA Mary Frances Early College of Education. "You have these ...

Math's top prize, the Fields Medal, has succeeded in making mathematics more inclusive but still rewards elitism, according to a Dartmouth study. Published in Nature's END ...

Researchers at the Johns Hopkins Kimmel Cancer Center used machine learning techniques to detect mutational signatures in cancer patients. Their algorithm outperformed the current standard of analysis and revealed new mutational signatures associated with obesity, which is believed by cancer prevention experts to be becoming the most significant lifestyle factor contributing to cancer in the U.S. and most of the Western world. The study was published in the Jan. 25 issue of the journal eLife. "Mutational signatures are important in current cancer research as they enable you to see the signs left by underlying factors, such as aging, smoking, alcohol use, UV exposure, and BRCA inherited mutations that contribute to the development ...

Making people fear the coronavirus may motivate us to wash our hands, keep our distance and wear a face mask. But fear also takes a heavy toll on our mental health and is fertile ground for discrimination and prejudice. New research shows a different path. When the coronavirus pandemic hit the world in the spring of 2020, feelings of being capable or efficacious against the virus were a key factor in driving compliance with the authorities' guidelines. This is the result of a new study based on large surveys across eight Western democracies, published in British Journal of Health Psychology. The extent to which we personally felt informed and capable of acting clearly affected the extent of our behaviour to prevent infection, e.g. by keeping our distance ...

A team of researchers at the Technical University of Munich (TUM) has developed a new early warning system for vehicles that uses artificial intelligence to learn from thousands of real traffic situations. A study of the system was carried out in cooperation with the BMW Group. The results show that, if used in today's self-driving vehicles, it can warn seven seconds in advance against potentially critical situations that the cars cannot handle alone - with over 85% accuracy. To make self-driving cars safe in the future, development efforts often rely on sophisticated models aimed at giving cars the ability to analyze the behavior of all traffic participants. But what happens if the models are not yet capable of handling some complex ...

Drinking beetroot juice promotes a mix of mouth bacteria associated with healthier blood vessels and brain function, according to a new study of people aged 70-80. Beetroot - and other foods including lettuce, spinach and celery - are rich in inorganic nitrate, and many oral bacteria play a role in turning nitrate to nitric oxide, which helps to regulate blood vessels and neurotransmission (chemical messages in the brain). Older people tend to have lower nitric oxide production, and this is associated with poorer vascular (blood vessel) and cognitive (brain) health. In the new study, by the University of Exeter, 26 healthy older people took part in two ten-day supplementation periods: one with nitrate-rich ...

Increasing numbers of people in Belgium are turning away from meat in favour of plant-based alternatives, according to new research from psychologists at the University of Bath, in collaboration with Belgian animal welfare organisation GAIA. New analysis finds that in 2020, over half of Belgians (51%) were 'satisfied' with meat alternatives - a figure that has increased from 44% since 2019. The results of the research which gauged responses from a representative sample of 1,000 people in Belgium over two years (in 2019 and 2020) highlights concerns around animal agriculture and the environment that are impacting individuals' dietary choices. Additional findings from ...

Computer scientists at the University of Surrey have created a ground-breaking model that could improve our understanding of developmental disorders such as autism. Scientists have long tried to better understand how the cerebral cortex and its layers develop, with pathologies such as autism, schizophrenia and epilepsy linked to this process. In a paper published by the journal Cerebral Cortex, scientists from Surrey, Newcastle University, and Nottingham University detail how they developed and used a computational model to simulate cell division, cell migration and apoptosis (cell death) in the hope of understanding how these processes affect the development of the brain. With the help of their computer model, the ...

A study examining bean productivity among smallholder farmers in Tanzania, has found that on average, yields are 6% lower among female than male farmers. Women are often 'invisible' in agriculture, researchers say, due to social structural barriers and national agricultural policies, which do not address discriminatory land rights; education and agricultural information and decision making, which must be tackled to reverse this trend. The paper 'What Does Gender Yield Gap Tell Us about Smallholder Farming in Developing Countries?' published in the open access scientific journal Multidisciplinary Digital Publishing (MDPI), analyzed data from southern region in Tanzania since 2016 and also drew on research ...

'A transmissible cancer was first discovered in dogs in the middle of the 19th century. It is transmitted sexually from a sick dog to a healthy one, the cancer cells themselves being the infective agent. In the 1990s, a contagious cancer was discovered in the Tasmanian devil. Since the cancer was found in only two species of mammals, scientists used to think that it is quite rare in the nature. However, time has come to reconsider this view. A transmissible cancer appears to be fairly widespread among bivalve molluscs,' says Maria Skazina, a research associate at the ...

DALLAS - March 30, 2021 - UT Southwestern researchers have identified factors that put patients with childhood-onset lupus at elevated risk for poor outcomes, such as end-stage renal disease or death, as they transition from pediatric to adult health care. The findings, published online in Seminars in Arthritis and Rheumatism, emphasize the precarious nature of this period and shine a spotlight on areas prime for intervention to help protect these vulnerable patients. Patients with chronic diseases that used to be fatal early in life now often survive to live long lives. However, says study senior author END ...

Babies can recognise combinations of words even before they have uttered their first word, a study suggests, challenging ideas of how children learn language. Assessments in 11-12 month-olds show that infants at the cusp of talking are already processing multiword phrases such as 'clap your hands'. Researchers say the study is the first to provide evidence that young children can pick up and understand multiword sequences before they can talk or begin producing such combinations themselves. The findings suggest that babies learn individual words and more complex phrases at the same time, which challenges the perspective that they progress from single words to phrases and sentences, experts say. It may also explain why adults who learn a new language in later life ...

The first online advertisement was a banner for AT&T that appeared on the HotWired.com website in 1994, when there were just 30 million internet users worldwide. Today, 57% of the world's population has access to the internet and advertising technology has advanced to the point that by 2018 the digital advertising market in Europe alone was worth 55 billion euros. Of this amount, 16.8 billion euros is accounted for by programmatic advertising, which uses artificial intelligence to automate much of the buying and selling of internet advertising. A new report, published by Open Evidence, a ...

Water quality management in the ocean often targets visible pollution sources such as sewage, rivers or ships. A new global study, led by researchers at the University of Gothenburg, reveals that invisible groundwater discharges may be just as important driving nitrogen into coastal waters. As we enter the United Nations' Decade of the Oceans, a new research study shed light on an often overlooked source of impact on the coastal ecosystems. The study, which examined groundwater discharges at more than 200 locations worldwide, showed that groundwater is the major source of nitrogen and phosphorus to the ocean at many locations, including some areas in the Baltic Sea. "Groundwater is essentially invisible and difficult to investigate. That ...
