NEW YORK, April 23, 2024 — Single-photon emitters (SPEs) are akin to microscopic lightbulbs that emit only one photon (a quantum of light) at a time. These tiny structures hold immense importance for the development of quantum technology, particularly in applications such as secure communications and high-resolution imaging. However, many materials that contain SPEs are impractical for use in mass manufacturing due to their high cost and the difficulty of integrating them into complex devices. In 2015, scientists discovered SPEs within a material called hexagonal boron nitride (hBN). Since then, hBN has gained widespread attention and ...

Palaeontologists at University College Cork (UCC), Ireland, have solved a hundred-year-old mystery of how some fossil frogs preserve their fleshy parts – it’s all down to their skin.  Palaeontologists Daniel Falk and Prof. Maria McNamara, together with scientists from Ireland, Germany and the UK, studied 45-million-year-old fossil frogs from the Geiseltal site in central Germany. Remarkably, the fossils show full body outlines of the soft tissues. The team discovered that the excellent condition of the fossil frogs is due to preservation of ancient skin remnants.  The team studied the fossils with high-precision ...

Existing drugs studied in patients with rare immune diseases This month the first study within the DRIMID consortium (DRIMID stands for Drug Rediscovery for Rare Immune Mediated Inflammatory Diseases) has started. This study will investigate the efficacy and safety of the drug filgotinib (approved for treatment of rheumatoid arthritis and ulcerative colitis) in three rare immune diseases (Behçet's disease, idiopathic inflammatory myositis, IgG4-related disease). DRIMID aims to investigate whether this drug - despite the absence of formal ...

A new study conducted by researchers at Loma Linda University Children’s Health has shed light on the alarming rates of pediatric injuries resulting from mechanical bull riding. The study, titled "Mechanical Bull Injuries in Pediatric Patients: A Call for Safety Regulations," highlights the urgent need for enhanced safety measures and regulations. The findings were published in the journal Children's Health Care and revealed that mechanical bull riding poses a significant risk to children, with traumatic brain injuries being the most common outcome.  “Mechanical bulls, even when ...

ROCKVILLE, Md.— Compared to their civilian counterparts, excessive pregnancy weight gain is more frequent among military health care beneficiaries, in particular active duty personnel, and is associated with costly maternal/neonatal complications. Women in this sample with excessive pregnancy weight gain were also three times more likely to have substantial postpartum weight retention, according to a new study published in the journal Obesity, The Obesity Society’s (TOS) flagship journal. Substantial weight retention ...

Body odor from the armpits comes from bacteria metabolizing sweat produced by the apocrine glands. These bacteria are native to our skin, but the odors produced differ among people. Generally, people use deodorants on their armpits, but perhaps there is a way to get rid of the bacteria. To find out, a research team led by Osaka Metropolitan University Professor Satoshi Uematsu and Associate Professor Kosuke Fujimoto at the Graduate School of Medicine collected body fluid samples from the armpits of 20 men that were deemed healthy. In advance, a subjective olfactory panel classified ...

When it comes to matters of the heart, cardiovascular disease in women is underdiagnosed compared to men. A popular scoring system used to estimate how likely a person is to develop a cardiovascular disease within the next 10 years is the Framingham Risk Score. It is based on factors including age, sex, cholesterol levels, and blood pressure. Researchers in the US and the Netherlands have now used a large dataset to build more accurate cardiovascular risk models than the Framingham Risk Score. They also quantified the underdiagnosis of women compared to men. The results were published in Frontiers ...

Korea relies on imports for most of its metal resources, and in recent years, due to resource depletion and rising raw material prices, 'circular resources' that recycle waste metal resources have emerged. In response, SK hynix has established a mid- to long-term plan to increase the percentage of copper, gold, etc. recovered and reused from waste generated in the semiconductor manufacturing process to more than 30% by 2030, and Samsung Electronics is running a collection program for used mobile phones in cooperation with E-circulation Governance, a non-profit corporation. The global circular economy market is expected ...

A University of Adelaide study of shallow-water fish communities on rocky reefs in south-eastern Australia has found climate change is helping tropical fish species invade temperate Australian waters. “The fish are travelling into these Australian ecosystems as larvae caught in the Eastern Australian Current, which is strengthening due to the warming climate,” said the University of Adelaide’s Professor Ivan Nagelkerken, Chief Investigator of the study. “These larvae would not normally survive in the cooler Australian ...

A Curtin University study has revealed breeding less-flatulent cows and restoring agricultural land could significantly reduce rising methane emission levels, which play a considerable role in climate change.   The food system, including grazing animals such as cows, generates major sources of methane mainly due to cattle digestion, manure decomposition and land use for grazing.   To look for solutions, researchers from the Curtin University Sustainability Policy Institute analysed 27 academic publications and identified dozens of potential strategies to reduce methane emissions from Australia’s beef and dairy sectors.   Study ...

Lateropulsion, a clinical condition which results in the body leaning to one side, affects about half of all stroke survivors.     Edith Cowan University (ECU) PhD graduate Dr Jessica Nolan said while the problem is common, lateropulsion is still severely under recognised and under assessed around the world.    “A person with lateropulsion uses the limbs on their stronger side, to push themselves over toward their weaker side. Often those with lateropulsion resist correction back towards their stronger ...

Reinforcement learning (RL) is a machine learning technique that trains software by mimicking the trial-and-error learning process of humans. It has demonstrated considerable success in many areas that involve sequential decision-making. However, training RL models with real-world online tests is often undesirable as it can be risky, time-consuming and, importantly, unethical. Thus, using offline datasets that are naturally collected through past operations is becoming increasingly popular for training and evaluating RL and bandit ...

Researchers at the University of Arizona College of Medicine – Tucson were awarded a $1.8 million grant by the National Institute of General Medical Sciences, a division of the National Institutes of Health, to learn how human papillomavirus makes its way to a cell’s nucleus. Human papillomavirus, or HPV, which can cause warts and certain cancers, has been with us since the dawn of humanity and causes about 5% of cancers worldwide. It also is an important source of information about human biology, according to Samuel K. Campos, PhD, an associate professor of immunobiology at the University of Arizona College of Medicine ...

A new study has found there are no adverse long-term cardiovascular health consequences for the now-adult children of mothers who were given corticosteroids because they were at risk of early birth in a landmark trial conducted in Auckland, New Zealand, 50 years ago. The Auckland Steroid Study by obstetrician Professor Graham ‘Mont’ Liggins and paediatrician colleague Dr Ross Howie from 1969 to 1974 in Green Lane Hospital, Auckland, found that two corticosteroid injections given to pregnant women at risk of early (preterm) birth halved the incidence of respiratory distress in the babies and significantly reduced neonatal deaths. Co-author of the new study, Dr ...

Active military service may heighten a woman’s risk of having a low birthweight baby, suggests a review of the available scientific evidence published online in the journal BMJ Military Health.   The findings highlight the need for more research specifically focused on women in the armed forces, and their reproductive health in particular, conclude the study authors. Worldwide, increasing numbers of women are on active service in their country’s armed forces. The UK Armed Forces, for example, has set a target of 30% female representation by 2030. And more and more countries are deploying women in combat ...

National clinical guidelines for the treatment of COVID-19 vary significantly around the world, with under-resourced countries the most likely to diverge from gold standard (World Health Organization; WHO) treatment recommendations, finds a comparative analysis published in the open access journal BMJ Global Health.   And nearly every national guideline recommends at least one treatment proven not to work, the analysis shows. Significant variations in national COVID-19 treatment recommendations have been suspected since the advent of the pandemic, but these haven’t been ...

Health concerns are still the primary motive for more than half of those who say they want to stop smoking in England, but cost is now a key factor for more than 1 in 4, finds an analysis of national survey responses, published in the open access journal BMJ Public Health. Given this shift in thinking, making much more of the potential savings to be had might encourage more people to stub out for good, suggest the researchers. Health concerns are generally the primary motive for people trying to stop smoking, with social and ...

Anti-N-methyl-d-aspartate (Anti-NMDA) receptor encephalitis is an acute autoimmune disorder that develops both neurological symptoms and psychiatric symptoms, including hallucination, cognitive disturbance, epilepsy, movement disorder, and impaired consciousness. This disease may be misdiagnosed at the early stage as a psychosis disease because of primary psychiatric symptoms. The misdiagnosis may delay appropriate therapeutic intervention. Most patients with anti-NMDA receptor encephalitis respond to immunotherapy [1, 2]. The pathology of this disease is ...

A new case report published in the peer-reviewed OMICS: A Journal of Integrative Biology describes how longitudinal multi-omics monitoring (LMOM) helped to detect a precancerous pancreatic tumor and led to a successful surgical intervention. Click here to read the article now.  The patient had undergone annual blood-based LMOM, in which 143 endogenous metabolites in serum and a panel of 140 proteins in plasma were measured. David Wishart, PhD, from the University of Alberta, ...

Working memory is one of the brain’s executive functions, a skill that allows humans to process information without losing track of what they’re doing. In the short term, working memory allows the brain to complete an immediate task, like loading the dishwasher. Long term, it helps the brain decide what to store for future use, such as whether more dishwasher soap will be needed. University of Texas at Arlington researchers know that working memory varies greatly among individuals, but they aren’t sure exactly why. To better understand, Matthew Robison, assistant professor of psychology, and doctoral student Lauren D. Garner conducted an experiment to see if ...

The fierce competition between China and the United States of America for control of emerging technologies such as AI and 5G will determine the international balance of power, a new study says. Developments in quantum computing, the Internet of Things, and Big Data have transformed the global order and have led to new alliances and dynamics, the analysis shows. Forming new allies has become imperative for the USA because the country cannot address the challenges posed by China in isolation. This has involved sharing sensitive advanced technologies with national security and ...

Imagine your greatest fear. Now, write it down and tell it in first-person, as if it’s happening right now. Vividly describe what it looks, sounds, smells, tastes and feels like. Don’t hold back. Such an exercise could be daunting for anyone, dredging up feelings we try to avoid. But for late-stage cancer patients struggling with anxiety and other mental health issues, it can be remarkably therapeutic, new CU Boulder research has found. “It’s often easier to write about something traumatic than to speak it out loud, especially to someone ...

A new study by researchers at National Jewish Health published this month in the  Annals of Allergy, Asthma & Immunology reports that air pollutants — including particulate matter, pollen, greenhouse gases, and other harmful substances — can contribute to the development and exacerbation of allergic diseases by disrupting the skin barrier. “People are aware of the connection between pollution and respiratory disease, but we wanted to take the next step and investigate how global warming is damaging ...

In the United States, the number of so-called progressive prosecutors focused on criminal justice reform has risen, but few studies have addressed the relation between these prosecutors’ policies and crime rates. In a new study, researchers examined whether progressive prosecutors in the 100 most populated counties affected crime rates from 2000 to 2020. They found that the inauguration of these prosecutors led to higher relative rates of property crime and total crime, but not to higher relative rates of violent crime. The study was conducted by researchers ...
