A new look into addiction treatment availability in the U.S. criminal justice system reveals that fewer than half (43.8%) of 1,028 jails surveyed across the nation offered any form of medication for opioid use disorder, and only 12.8% made these available to anyone with the disorder. With two-thirds of people who are incarcerated in U.S. jails experiencing a substance use disorder – in many cases, an opioid use disorder – the failure to make these medications widely available in criminal justice settings represents a significant missed opportunity to provide life-saving treatments in an environment where people in need of care can be easily reached. The study, published ...

What: Cancer incidence trends in 2021 largely returned to what they were before the COVID-19 pandemic, according to a study by researchers at the National Institutes of Health (NIH). However, there was little evidence of a rebound in incidence that would account for the decline in diagnoses in 2020, when screening and other medical care was disrupted. One exception was breast cancer, where the researchers did see an uptick in diagnoses of advanced-stage disease in 2021. The study appears Sept. 24, 2024, in the Journal of the National Cancer Institute. A previous study showed that new cancer diagnoses fell abruptly ...

A study, published in the journal Nature Communications by an international team of climate scientists and permafrost experts shows that, according to new climate computer model simulations, global warming will accelerate permafrost thawing and as a result lead to an abrupt intensification of wildfires in the Subarctic and Arctic regions of northern Canada and Siberia. Recent observational trends suggest that warm and unusually dry conditions have already intensified wildfires in the Arctic region. To understand ...

A review of sustained mammal-to-mammal bird flu transmission in diverse species, led by The Pirbright Institute, shows global control strategies are not working. Writing in Nature, researchers analysed whether outbreaks in European fur farms, South American marine mammals and United States dairy cattle raise questions about whether humans are next. Led by zoonotic influenza specialist Dr Thomas Peacock, the scientists evaluated how recent changes in the ecology and molecular evolution of H5N1 in wild and domestic birds increase opportunities for spillover ...

Until a few years ago, the butterfly known as the southern small white could barely be found north of the Alps. That was before a Europe-wide invasion that brought a huge increase in the insect’s distribution – at the same time as a rapid decrease in genetic diversity within the species. It took a while for zoologist Daniel Berner to notice that a butterfly species that wasn’t local to his area had become established in his garden. Then, suddenly, he saw it everywhere: Pieris mannii – also known as the southern small ...

The skeletal remains of a senior officer of Sir John Franklin's 1845 Northwest Passage expedition have been identified by researchers from the University of Waterloo and Lakehead University using DNA and genealogical analyses.   In April of 1848 James Fitzjames of HMS Erebus helped lead 105 survivors from their ice-trapped ships in an attempt to escape the Arctic. None would survive. Since the mid-19th century, remains of dozens of them have been found around King William Island, Nunavut.   The identification was made possible by a DNA sample from a living descendant, which matched the ...

As one of the key materials of modern microwave communication technology, microwave dielectric ceramics are widely used in many core components of microwave circuits. In recent years, with the rapid development of microwave communication technology marked by mobile communication, in order to meet the requirements of the development of mobile communication technology, including 5G/6G, new requirements have been put forward for the performance parameters of microwave dielectric ceramics: low dielectric constant to reduce signal delay, low dielectric loss or high quality factor, and near-zero ...

Diffuse midline glioma (DMG) is a highly aggressive and fatal pediatric high-grade glioma that primarily affects critical regions of the central nervous system, such as the pons, thalamus, and spinal cord. Due to the high surgical risks and poor prognosis associated with DMG, treatment options for patients are extremely limited. Conventional treatments, including surgery, radiotherapy, and chemotherapy, have shown limited efficacy, particularly with radiochemotherapy, which only temporarily controls tumor progression ...

Changes in silage production could help cut greenhouse gas emissions from agriculture. Agriculture is the largest source of nitrous oxide (N2O) emissions in the United States. N2O is the third most impactful greenhouse gas, yet one potential source—silage—has not been thoroughly studied. Silage, which is moist, harvested plant material used to feed livestock during the winter, is preserved through fermentation. During this process, anaerobic bacteria produce lactic acid, which prevents the plants from spoiling. Jeongdae Im and colleagues suggest that silage could be a significant ...

Artificial intelligence (AI) may reshape many industries, but the impact of the nascent technology on various jobs remains unclear. Daniele Quercia and colleagues used machine learning to investigate itself, by identifying patents for AI technologies that may impact various occupational tasks. The model used a dataset of 17,879 task descriptions from O*NET, a US government-run occupations database, as well as 24,758 AI patents filed with the United States Patent and Trademark Office between 2015 and 2022 and measured semantic similarity between occupation task descriptions and patent descriptions. The analysis was not merely an exercise ...

A proof-of-concept study promises the speedy diagnosis of lower respiratory tract infections through analysis of human breath. Lower respiratory tract infections, such as bronchitis, pneumonia, and bronchiolitis, are currently diagnosed by culturing bacteria from respiratory specimens, but the procedure is invasive, laborious, and time intensive. Molecular sequencing techniques cannot differentiate between clinical infection and mere colonization, in which bacteria are benignly present in the respiratory tract. Dapeng Chen and colleagues have designed a medical device that measures the protease activity ...

In a Perspective, Holly C. White and colleagues argue that student well-being should be a goal of pedagogy, along with traditional metrics such as GPA and student retention. Despite evidence linking certain academic experiences with well-being outcomes, few students report having had such experiences. Well-being is defined as a sense of belonging, agency, purpose, identity, civic engagement, and financial well-being. The authors summarize data-backed teaching practices that support elements of student well-being, including supportive mentorships and experiential or authentic learning opportunities. Six exceptional initiatives are described, which can act as models ...

It’s almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists reporting in ACS Nano have made their own version of fake spider silk, but this one consists of proteins and heals wounds instead of haunting hallways. The artificial silk is strong enough to be woven into bandages that helped treat joint injuries and skin lesions in mice. Spider silk is one of the strongest materials on Earth, technically stronger than steel for a material of ...

Hydrogen gas, owing to its high energy density and carbon-free nature, is gaining much attention as the energy source for a green and sustainable future. Despite being the most abundant element in the universe, hydrogen is mostly found in a bound state as chemical compounds such as ammonia, metal hydrides, and other hydrogenated compounds. Among all the hydrogen carriers, ammonia stands out as a promising candidate owing to its wide availability, high hydrogen content with hydrogen making up 17.6% of its mass, and ease of liquefaction as well as transportation. A major drawback that hinders its exploitation as an ...

Despite a substantial Nepalese community in Japan many Nepalese women face significant challenges in accessing essential sexual and reproductive health services (SRHSs) due to language barriers and differences in healthcare laws and services between Nepal and Japan. In Nepal, women have free access to a wide range of contraceptive and abortion services, while Japan places more restrictions on certain contraceptives and does not provide free abortion services. These limited options make women more reliant on their male partner to use contraceptives for birth control. These challenges in accessing contraceptives, especially female-oriented contraceptives, lead them to acquire contraceptives ...

Parkinson’s disease (PD), also known simply as Parkinson’s, is a disorder of the nervous system that affects millions of people worldwide. The nerve cell damage associated with Parkinson’s can cause tremors, slowed movements, problems with balance, and many other symptoms which worsen gradually over time. Although there is no cure, there are medications available that can treat PD symptoms. Some of these medications, however, have previously unexplained side effects – including impaired decision-making that leads to potentially harmful behaviors such as pathological gambling, binge eating and compulsive shopping. Now, in ...
