Northeast Greenland is home to the 79° N Glacier – the country’s largest floating glacier tongue, but also one seriously threatened by global warming: warm water from the Atlantic is melting it from below. Experts from the Alfred Wegener Institute have however now determined that the temperature of the water flowing into the glacier cavern declined from 2018 to 2021, even though the ocean has steadily warmed in the region over the past several decades. This could be due to temporarily changed atmospheric circulation patterns. ...

WASHINGTON, Sept. 24, 2024 – Coastlines are vital to our world’s ecology and economy. Coastal ecosystems help maintain biodiversity, provide natural barriers against erosion, storms, and flooding, and act as large carbon sinks to reduce greenhouse gases. Sustainable fisheries and seaside tourist venues support local economies. Natural coastlines, including coral reefs, marshes, and mangroves, are complete and stable, capable of self-regulation and restoration. That is, unless human interventions, such as urbanization, overdevelopment, pollution, and human-made erosion, make these areas vulnerable to devastation. Artificial coastlines, ...

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 ...
