Researchers at the University of Bath in the UK are proposing thresholds for safe – or at least safer – cannabis use and hope their findings will help people monitor consumption and keep it within recommended limits – similar to how alcohol units guide safer drinking. The threshold recommendations, proposed in a paper published today in the journal Addiction, are based on a system for measuring cannabis consumption not by weight but by THC content (THC is the compound responsible for the psychoactive effects of cannabis). In the same ...

In about 5–10% of colorectal cancer patients, hereditary factors play a role, with higher percentages among younger patients. Research from Radboud university medical center and university hospital Bonn (UKB) in collaboration with researchers from Munich and Barcelona, shows that DNA analysis of colorectal polyps provides important additional information on the development of these polyps and colorectal cancer. This DNA analysis leads to better diagnostics and treatment ...

Leuven, January 12, 2026 – Researchers at VIB and KU Leuven have identified a molecular process that allows motor neurons to maintain protein production, a process that fails in amyotrophic lateral sclerosis (ALS). The study, published in Nature Neuroscience, reveals an early weakness in neurodegeneration and highlights a potential target for future therapies. Building proteins Motor neurons depend on local protein production within their axons to support their long-distance connections to muscles. Using advanced spatial transcriptomics, scientists at the VIB–KU Leuven Center for Brain & Disease Research analyzed gene expression ...

Rates of multiple myeloma (MM), the second most common blood cancer in the United States, are increasing and are twice as high in men than in women. A new study published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society, provides insights that may help to explain this disparity. To investigate the sex difference in MM, researchers analyzed data on 850 patients with newly diagnosed MM enrolled in the Integrative Molecular And Genetic Epidemiology (IMAGE) study at the University of Alabama at Birmingham. Compared with female patients, male patients were more likely to have advanced (International Staging System stage III) disease at the time of diagnosis. Males ...

by W.B. Kagan PISCATAWAY, NJ – Young adults today are digital natives—naturally fluent with devices and online platforms—so some of their most effective behavioral-health interventions will likely arrive in their pockets via text, app, or other mobile medium. Now, new research shows that such interventions for alcohol and cannabis use among young adults show potential to reduce harms, according to three reports in the Journal of Studies on Alcohol and Drugs. Heavy drinking and cannabis use among young adults continue to exact a great cost from individuals and society, ...

How do health care professionals in Canada assess applicants for medical assistance in dying (MAiD)? A research article in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.251071 describes the careful approach currently used to determine eligibility, and an analysis article suggests an approach to eligibility assessments for advance requests for MAiD — which are currently available in Quebec and being considered elsewhere in Canada. In 2021, Canada ...

Air-polluting microplastics have been found in rural environments in greater quantities than in urban locations, researchers say.  Scientists led by the University of Leeds detected up to 500 microscopic particles of plastic per square metre per day in an area of woodland during the three-month study – almost twice as much as in a sample collected in a city centre.  They believe trees and other vegetation capture airborne microplastic particles from the atmosphere and deposit them, highlighting the impact ...

Veteran male athletes who have spent years training at high intensity may be at greater risk of serious heart problems while exercising, new University of Leeds research shows.   Published today and funded by the British Heart Foundation, the study shows that male endurance athletes aged over 50 may be more likely to experience abnormal heart rhythms during training if they already have scarring in their heart.   Nine in 10 sudden cardiac deaths during sport occur in older male athletes.  The researchers’ aim ...

“We know the genes, but not their functions.” To resolve this long-standing bottleneck in microbial research, a joint research team has proposed a cutting-edge research strategy that leverages Artificial Intelligence (AI) to drastically accelerate the discovery of microbial gene functions. KAIST announced on January 12th that a research team led by Distinguished Professor Sang Yup Lee from the Department of Chemical and Biomolecular Engineering, in collaboration with Professor Bernhard Palsson from the Department of Bioengineering at UCSD, has published a comprehensive review paper. The study systematically analyzes and organizes the latest AI-based ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have developed a suite of algorithms to automate the counting of sister chromatid exchanges (SCE) in chromosomes under the microscope. Conventional analysis requires trained personnel and time, with variability between different people. The team’s machine-learning-based algorithm boasts an accuracy of 84% and gives a more objective measurement. This could be a game changer for diagnosing disorders tied to abnormal numbers of SCEs, like Bloom syndrome.   DNA, the blueprint of life for all living organisms, is found packaged inside complex ...

The U.S. boasts more than 4 million miles of rivers, peppered with laws and regulations to protect access to drinking water and essential habitat for fish and wildlife. But in the first comprehensive review of river protection, research co-led by the University of Washington shows that the existing regulations account for less than 20% of total river length and vary widely by region. Freshwater conservation strategies have historically emphasized protections against land use and development on public ...

Professor Zhaohui Tang and Associate Professor Zhilin Liu from the team of Professor Xuesi Chen at the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, developed  ultrasound-responsive in-situ antigen nanocatchers (S-nanocatchers), achieving precise spatiotemporal capture of tumor antigens and controllable acquisition of in-situ vaccines. This system solves the key problems of traditional antigen-capturing nanocarriers, such as their tendency to non-specifically bind to serum proteins during systemic circulation and their low antigen capture efficiency, providing a novel strategy for personalized tumor ...

Environmental antimicrobial resistance is turning rivers, soils, and even the air into hidden highways for “superbugs,” according to a new review that calls for urgent, coordinated action across human, animal, and environmental health. The authors argue that protecting people from drug resistant infections now depends as much on wastewater plants and farms as it does on hospitals. A growing environmental “superbug” crisis Antimicrobial resistance (AMR) occurs when bacteria and other microbes evolve the ability to ...

Invisible pollutants in high tech greenhouses may be quietly reshaping the food on our plates and the soil beneath our feet. A new open access review maps how heavy metals, micro and nanoplastics, and antibiotic resistance genes increasingly pile up together in intensive “facility agriculture” and why this triple cocktail demands urgent attention from scientists, farmers, and regulators. The paper reviews composite pollution in facility agriculture, a fast growing form of high yield farming that relies on greenhouses and other controlled environments to produce vegetables and other crops year round. ...

  Earthworms could become unexpected allies in the global fight against antibiotic resistance, by helping farmers turn manure into safer, high-value organic fertilizer through a process called vermicomposting. Researchers report that this low energy, nature-based technology can remove antibiotic resistance genes far more consistently than conventional composting, while also improving soil health and supporting sustainable agriculture. Antibiotic resistance from farm to table The World Health Organization has named antimicrobial resistance one ...

  Artificial intelligence is quietly transforming how scientists monitor and manage invisible biological pollutants in rivers, lakes, and coastal waters, and a new review explains how this technological shift could better protect ecosystems and public health.​ In a paper published in the open access journal Biocontaminant, researchers from Nanjing University outline how AI can turn water quality management from a reactive, after the fact process into a proactive early warning and control system for harmful microbes, algal toxins, parasites, and antibiotic resistance genes in aquatic environments. These living “biocontaminants” are highly ...

Biodegradable plastics are not always safer for rivers and oceans, according to a new study that tracked how different plastics change the risk of antibiotic resistant bacteria over time in a real river. A sharper look at “green” plastics A team from East China Normal University placed common plastics in a tidal river in Shanghai for 88 days to see how they shaped microbial “cities” on their surfaces, known as the plastisphere. The researchers compared a biodegradable plastic, polylactic acid (PLA), with two widely used conventional plastics, polyvinyl chloride (PVC) and polystyrene (PS).​ “Our findings show that biodegradable plastics ...

  A team of agricultural and environmental scientists has developed a simple biochar based technology that can strip self toxic chemicals from pepper growing soils and restore healthy seed germination. The work offers a promising new tool to help farmers overcome “continuous cropping obstacles” that have long plagued high value capsicum production. “Pepper farmers often feel forced to choose between meeting market demand and protecting their soil. Our study shows they do not have to make that trade ...

Planning to save time by doing your shopping online? If so, it’s possible you’re not doing your well-being any favours. A study from Aalto University in Finland has found that online shopping is more strongly linked to stress than reading the news, checking your inbox or watching adult entertainment. The internet can be both a source and a reliever of stress though, according to research –– so do we scroll because we’re stressed, or are we stressed because we scroll? It's a complex problem to unravel, according to doctoral researcher Mohammed Belal. ‘Previous studies have shown ...

ITHACA, N.Y. – Someone in the office makes a racially insensitive comment, and a white co-worker asks a Black colleague to help correct the offender. In three studies, a Cornell University researcher found that this kind of maneuver can backfire. In such scenarios, the marginalized person then views the person who asked for their help less favorably – and is less likely to want to associate with them in the future. “A marginalized person’s willingness to get involved in confronting prejudice is much more complicated than simply just trying to reduce prejudice in the workplace,” said Merrick Osborne, professor of organizational behavior at Cornell ...

Using a tiny, acid-tolerant yeast, scientists have demonstrated a cost-effective way to make disposable diapers, microplastics, and acrylic paint more sustainable through biomanufacturing. A key ingredient in those everyday products is acrylic acid, an important industrial chemical that gives disposable diapers their absorbency, makes water-based paints and sealants more weather-proof, improves stain resistance in fabric, and enhances fertilizers and soil treatments. Acrylic acid is converted from a precursor called 3-Hydroxypropanoic acid, or 3-HP, which is made almost exclusively from petroleum through chemical synthesis — an energy-intensive process. ...

Although constipation and diarrhea may seem like opposite problems, they both hinge on the same underlying issue: how much fluid moves into the gut. These common issues affect millions of people in the U.S. each year, yet scientists have not fully understood what regulates intestinal fluid balance. Now, in a new Northwestern University study, scientists have uncovered a key molecular switch that helps control the gut’s “water faucet.” By studying bisacodyl — one of the world’s most widely used laxatives — the research team discovered an ion channel, called TRPM4, acts as a master switch for controlling fluid flow in the intestine. The ...

GLP-1 medications like Ozempic and Wegovy have transformed obesity treatment, but maintaining weight loss after the medications stop remains a challenge. George Mason University is leading a new clinical trial that may help people sustain their results.   The university is one of six research sites across the U.S. administering a Phase 2 clinical trial of ARD-201, a novel weight-maintenance drug developed by Aardvark Therapeutics that works differently from existing obesity medications. Unlike injectable medications that drive ...

A new study published in Conservation Biology examines the behavior and distributions of queen conch (Aliger gigas) to guide conservation management for the threatened sea snail. The research, which tracked adult snail movements, suggests that establishing a 330-meter spatial buffer – about the height of the Eiffel Tower by comparison – around breeding areas could help protect conch populations and serve as a practical tool for local management. Queen conch are giant herbivorous marine snails that do not crawl slowly along and leave slime trails. Instead, ...
