The study suggests that treatments designed for obesity-associated fatty liver disease may not work as effectively in lean patients.
A regulator-mandated study found no link between semaglutide use and pancreatic cancer using nationwide registry data from Denmark, Sweden, and Norway. The study, funded by Novo, included over 97,000 semaglutide users and compared them to users of other non-incretin antidiabetic drugs.
A study of 57,611 UK Biobank participants found that fluctuations in blood pressure were associated with a higher risk of death and strokes. The study suggests that blood pressure variability could help identify high-risk patients, but more research is needed to prove its benefits.
A new AI-based tool uses speech analysis to detect type 2 diabetes in just 20 seconds, with high accuracy rates. The model performed well across different sexes and ages, but had lower performance on recordings from Black participants and those with heart disease, high blood pressure, or obesity.
A study of 2 million adults in Ontario, Canada, found that moving from a high-poverty to a lower poverty neighbourhood significantly lowers the risk of developing type 2 diabetes. Individuals who moved experienced a 57% lower risk compared to those who remained in the same high-poverty area.
A seven-year study of Barred Owls in California shows a significant decline in exposure to the most lethal class of rodenticides, attributed to the state's policy restrictions. The study also detects a new contaminant, cholecalciferol, in nearly one in five owls, suggesting product substitution as older compounds become harder to access.
A new study published in Cell Reports found that the visual cortex establishes targeted, region-specific neural connections early in postnatal development, challenging the exuberant growth model. The research team mapped the connections of thousands of neurons using advanced viral and molecular tracing techniques, revealing a refined w...
Rutgers engineers have developed a smart shoe that automatically analyzes how a person walks, tracking movement and calories burned with 95.4% accuracy. The prototype powers the analysis with energy generated from the wearer's footsteps, offering a potential solution to the 'energy-intelligence bottleneck' in existing health wearables.
Researchers found implanting collagen tiles during brain surgery to deliver targeted radiation therapy improves tumor control, lowers recurrence risk, and increases overall survival.

Researchers concluded that supervised exercise therapy combined with education offers meaningful short-term benefits for young adults with...
Researchers at the University of Pennsylvania School of Medicine found that medetomidine withdrawal cases have quadrupled in recent years due to its increased potency in the illicit opioid supply. Patients experiencing withdrawal symptoms, including tachycardia and organ damage, require specialized treatment, including dexmedetomidine ...
Researchers at the University of Texas at Austin have redated a meteor impact site in Oklahoma, shifting its age from 467.5 million years ago to 370 million years ago. This discovery has significant implications for understanding ancient life and mass extinctions.
Researchers at Sanford Burnham Prebys discovered that blocking an energy transfer enzyme shifts mammalian hearts into a regenerative state, promoting regeneration and improving recovery after a heart attack. By modulating heart cell metabolism, scientists can potentially awaken the heart's dormant regenerative abilities.
A new study by an international team provides the first systematic cross-cultural comparison of children's helping behaviour. Across six cultures, children consistently helped peers, with younger children providing practical assistance and older children offering information to solve problems. Cultural differences emerged, with some gr...
Researchers at Oregon State University have developed a new material that uses light to produce hydrogen from water, offering a cleaner alternative to current methods and potentially reducing greenhouse gas emissions. This breakthrough could simplify the production of fuel cells and chemicals, while also providing a more sustainable en...
California's decision to add microplastics to its Candidate Chemicals List marks a significant step towards regulating plastic pollution. The move is part of the state's decade-long regulatory approach, which has also included banning plastic microbeads in cosmetics.
A study by VCU medical students found that nearly 1 in 5 GLP-1 users spent at least 10% of their household income on the medications, while 7% of patients spent an average of 7% of their household income annually. The researchers emphasize the need for solutions to make GLP-1 medications more affordable, particularly among uninsured an...
The National Commercialization and Translation Institute (NCTI) aims to accelerate commercialization of promising technologies by studying late-stage federally funded companies. UCF Professor Ivan Garibay will lead the institute, building on existing federal research translation and commercialization programs.
A multicenter study found that fractionated stereotactic radiosurgery reduced brain metastases recurrence and improved survival rates compared to single treatment. The approach delivered higher total doses and allowed healthy tissue to recover between treatments, while tumor cells couldn't repair.
Zhen Xu, U-M Engineering professor, wins Golden Goose Award for development of histotripsy, a noninvasive cancer treatment. The technology has been used to treat over 5,000 patients worldwide and has the potential to treat various diseases, including brain diseases and cardiovascular diseases.
Ochsner Health has expanded its pediatric and women’s healthcare services at The Grove, adding eight new physicians and upgraded clinical areas to serve more families across the Capital Region. Families can now access a wider array of specialized care for both adults and pediatric patients under one roof, with expanded appointment avai...
The NRG Oncology trial found that proton therapy did not improve overall survival or progression-free survival for patients with advanced hepatocellular carcinoma. However, fewer grade 3 or higher treatment-related adverse events were observed with proton therapy compared to photon therapy.
A University of Maryland study predicts that repealing Florida's measles vaccine mandate could spark the largest measles epidemic in the US in nearly 500 years. The study shows that even without mandate removal, Florida's vaccine-induced herd immunity threshold is below the level needed to protect against sustained transmission.
A Phase III trial found stereotactic radiosurgery (SRS) improved overall survival in patients with small cell lung cancer (SCLC) brain metastases without significant difference in neurocognitive outcomes compared to hippocampal-avoidant whole brain radiotherapy (HA-WBRT).
A UH study of 1,400 Maui adults found substantially elevated concentrations of metals in urine, associated with abnormal lung function. The study revealed complex exposure pathways, including those introduced by the wildfire and existing environmental factors.
Researchers developed an experimental mRNA therapy that reduces liver injury in mice, even when given at a much later point in time than the currently available antidote. The therapy harnesses a newly identified protective mechanism that helps liver cells survive acetaminophen-induced oxidative stress.
Researchers at Ohio State University are testing psilocybin-assisted therapy to reduce depression and emotional distress in patients with advanced lung cancer. The trial aims to determine whether this approach can address the unique psychological challenges faced by lung cancer patients.
