As wildfires grow larger and more frequent across the West, researchers from Colorado, Utah, and California are digging into how smoke affects the air—and our health.  In a new study published in the journal Atmospheric Environment, the team shows that large wildfires, like those we’ve seen in Colorado, Oregon, and California in recent years, produce large amounts of ozone into the atmosphere. This not only impacts our lungs and other health concerns but also contributes to the warming of the planet.  CU Denver mathematics professor emeritus Jan Mandel was part of the research team, which included faculty from the University ...

Quantum physics often reveals phenomena that defy common sense. A new theory of quantum scarring deepens our understanding of the connection between the quantum world and classical mechanics, sheds light on earlier findings and marks a step forward towards future technological applications. Quantum mechanics describes the behaviour of matter and energy at microscopic scales, where randomness seems to prevail. Yet even within seemingly chaotic systems, hidden order may lie beneath the surface. Quantum scars are one such example: they are regions where electrons prefer to travel along ...

A University of Helsinki study found that partially replacing red and processed meat with pea- and faba bean–based foods resulted in reduced total and ‘bad’ LDL cholesterol levels in men, along with weight loss. On average, men consume significantly more red and processed meat than is recommended, and more than women do. The high nutritional value of legumes makes them well suited to replacing meat. However, they do not naturally contain vitamin B12, which is found in animal-derived foods. The BeanMan study investigated how partially replacing red and ...

Colorectal cancer (CRC) remains a leading cause of cancer-related mortality worldwide, with rising incidence attributed to environmental, dietary, and lifestyle factors. Beyond genetic and epigenetic drivers, increasing evidence implicates the gut microbiome as a crucial modulator of CRC initiation, progression, and therapeutic response. Dysbiosis—an imbalance in microbial composition—can disrupt intestinal homeostasis, promote chronic inflammation, and facilitate carcinogenesis. This review explores the mechanistic role ...

WASHINGTON–A new initiative by The Society for Cardiovascular Angiography & Interventions (SCAI) proposes a new framework and call to action for managing cardiogenic shock (CS), establishing lactate clearance potentially as the standardized, time-based marker of patient trajectory to improve outcomes in one of the deadliest cardiovascular emergencies.   “SCAI Door to Lactate Clearance (SCAI DLC) Cardiogenic Shock Initiative: Definition, Hypothesis and Call to Action” was unveiled September 19 at the SCAI SHOCK Conference in Tampa, FL, with simultaneous publication in JSCAI.  “Cardiogenic shock remains one of the deadliest ...

Neural Radiance Fields (NeRF) is a fascinating technique that creates three-dimensional (3D) representations of a scene from a set of two-dimensional (2D) images, captured from different angles. It works by training a deep neural network to predict the color and density at any point in 3D space. To do this, it casts imaginary light rays from the camera through each pixel in all input images, sampling points along those rays with their 3D coordinates and viewing direction. Using this information, NeRF reconstructs the scene in 3D and can render it from entirely new perspectives, a process known as novel view synthesis (NVS). Beyond still images, a video can also be used, with each frame of ...

New research reveals “unprecedented” conservation results of community-based management of protected areas in the Amazon - as many face a future in which they may become increasingly degraded due to low enforcement of regulations, growing external encroachment and competition for resources. The study describes a powerful new mechanism for increasing the extent of effective area-based protection by piggybacking on community management of natural resources. Tropical protected areas are typically understaffed, underfunded and underequipped and it remains unclear how existing ones ...

Bethesda, MD (Sept. 17, 2025) — The American Gastroenterological Association (AGA) has released a new clinical guideline with 12 conditional recommendations for diagnosing and managing gastroparesis, a serious and often debilitating disease. Rather than pointing to a single treatment path, the evidence highlights a range of options — underscoring the complexity of gastroparesis and the importance of thoughtful conversations between doctors and patients to tailor an individualized care plan.  Gastroparesis affects thousands of people, often causing nausea, postprandial fullness, vomiting, discomfort, and major disruptions to quality of life. The ...

Between 2nd  and 10th September around 40 stakeholders involved in protecting and restoring peatlands and wetlands in Germany, the Netherlands and Finland joined a series of online workshops to develop impact plans that aim to influence policies and markets in each country, to scale up the restoration of degraded peatlands.  The meetings were organised by the EU-funded research project WET HORIZONS, the UNEP’s Global Peatlands Initiative, Wetlands International, and Eurosite - the European Land Conservation Network, who are coordinating the European Peatlands Initiative.  “The ...

Performance in endurance sports, such as long-distance running, cycling, and cross-country skiing, requires sustained activity over prolonged periods of time, and is influenced by multiple factors, such as temperature and mental state. In chilly temperatures around 10°C (50°F), endurance performance has been shown to improve in certain circumstances. In contrast, extreme cold can slow down muscle and nerve function and cause a decline in performance. Such reactions suggest the involvement of the Sympathetic Adrenal-Medullary (SAM) system, a stress response pathway. Further performance decline can be attributed to mental fatigue caused by psychological pressure, which leads to decreased ...

Australian farmers face inconsistent guidelines when it comes to crop regulations across genetically modified (GM), organic and other crop frameworks, according to new research from the University of Adelaide. “Even though different sectors in Australian cropping regulate coexistence of both genetically modified and organic crops, they do so in different ways,” says lead researcher Michail Ivanov, whose review was published in Griffith Law Review. “For example, different standards or codes of conduct recommend different physical barriers or buffer zones between paddocks to ...

Researchers including those from the University of Tokyo have successfully grown large tomatoes and cherry tomatoes, both rich in nutrients, in tightly controlled environments where the light source was energy-efficient LEDs. Such methods were often limited by the types or sizes of plants that could thrive in such conditions. This feasibility study demonstrates the researchers’ method is suitable for urban environments, potentially even in space, and can offer food security in the face of climate change or extreme weather conditions. Pizza, pasta, soup, salad, the tomato ...

The Ig Nobel Prize honors research that first makes people laugh, then makes them think. Its 35th award ceremony possibly also makes people hungry: ISTA physicist Fabrizio Olmeda and colleagues researched the secret of a perfect cacio e pepe pasta sauce. They received the popular award for their findings on Thursday evening in Boston, USA. Cacio e pepe is one of Italy's most popular pasta dishes, but even (Italian) scientists often fail to prepare the perfect creamy sauce. Fabrizio Olmeda, a physicist at the Institute of Science and Technology Austria (ISTA), also struggled ...

Bright squeezed light, exhibiting sub-shot-noise quantum noise combined with significant optical power, is essential for enhanced sensitivity in quantum metrology and precision measurement. In the deep application within the field, the squeezing must be extended to kHz–MHz bandwidth with milliwatt optical power. However, it remains a longstanding challenge to achieve this goal with conventional technologies, since they suffer from low-frequency technical noise and vacuum noise coupling, which caps ...

A team of researchers, including those at the University of Tokyo, discovered that liquid water once flowed on the asteroid that spawned near-Earth asteroid Ryugu more than a billion years after it first formed. The finding, based on tiny rock fragments returned by the Hayabusa2 spacecraft of the Japan Aerospace Exploration Agency (JAXA), overturns long-held assumptions that water activity on asteroids only occurred in the earliest moments of solar system history. This could impact models which include the formation of the Earth. We have a relatively good ...

Scientists have developed and tested a deep-learning model that could support clinicians by providing accurate results and clear, explainable insights – including a model-estimated probability score for autism. The model, outlined in a study published in eClinicalMedicine (a journal from The Lancet), was used to analyse resting-state fMRI data – a non-invasive method that indirectly reflects brain activity via blood-oxygenation changes. In doing so, the model achieved up to 98% cross-validated accuracy for Autism Spectrum ...

The current process for managing sexual misconduct perpetrated by doctors in the UK requires major reform, say experts in The BMJ today. Mei Nortley and colleagues argue that sanctioning of doctors is inconsistent and overly reliant on subjective evidence and they call for a dedicated, evidence driven approach “that treats sexual misconduct by doctors not as a regulatory outlier, but as the grave abuse of trust it truly is.” They point to several recent high profile cases that have ...

The largest study on pregnant women with excessive nausea and vomiting (hyperemesis gravidarum) has identified increased risks of numerous neuropsychiatric and mental health outcomes.  Researchers from King’s College London and South London and Maudsley NHS Foundation Trust conducted a study involving 476,857 pregnant women diagnosed with hyperemesis gravidarum (HG) from 135 healthcare providers worldwide. The study is the first to explore an array of neuropsychiatric and mental health outcomes for women with HG.   They performed a retrospective cohort study using the TriNetX Global Collaborative Network, a network collecting anonymised electronic healthcare record ...

Continuous landmasses, now submerged, may have made it possible for early humans to cross between present-day Turkiye and Europe, new landmark research of this largely unexplored region reveals.   The findings, published today in the peer-reviewed Journal of Island and Coastal Archaeology, unveil a previously undocumented Paleolithic presence in Ayvalık and more importantly could redocument our species’ migration into the continent.   It has long been thought that Homosapien reached Europe primarily coming via the Balkans and the Levant, from Africa into the Middle East.  However, with this new discovery of 138 lithic artifacts at 10 sites, across a region ...

A team of scientists has discovered that the ability of biochar to conduct electricity can significantly affect methane emissions from rice paddies, one of the largest sources of agricultural greenhouse gases worldwide. Methane is a powerful greenhouse gas, with more than 27 times the warming effect of carbon dioxide. Rice paddies, covering about 9% of global farmland, contribute nearly one-third of agricultural methane emissions. Scientists have long debated whether adding biochar—charcoal-like material made from plant matter—can help reduce or increase these emissions. The new findings, published ...

A new editorial in Biocontaminant reports that Guangdong Province is experiencing the largest outbreak of chikungunya fever ever recorded in China, with more than 4,000 confirmed cases since late July. Shunde District of Foshan alone has reported over 3,600 infections, and cases have also spread to Guangzhou, Shenzhen, Hong Kong, and Macao. Chikungunya fever is transmitted by Aedes mosquitoes, the same vectors responsible for dengue and Zika. The disease, marked by fever and severe joint pain, does not spread directly between people, making mosquito control the key to prevention. “The outbreak reflects both the global spread of chikungunya and the favorable ...

New research shows that that the diabetes/obesity medication tirzepatide can cause clinically meaningful improvements in blood sugar control and weight loss in children and adolescents with type 2 diabetes aged 10-17 years whose diabetes and weight are inadequately controlled with an existing treatment regimen of metformin, insulin, or both. The study (the SURPASS-PEDS trial), by Dr Tamara Hannon, Division of Pediatric Endocrinology and Diabetology, Indiana University School of Medicine, Indiana University School of Medicine, Indianapolis, ...
