Research Highlights: A one-month course of dual clot-preventing therapy followed by a single clot-prevention medication for the remainder of the standard 12-month regimen in adults with atrial fibrillation (AFib) who received a coronary stent was as effective as one year of continuous dual therapy for preventing stroke, heart attack and death. Participants treated with the one-month regimen experienced fewer bleeding problems than those in the year-long dual-treatment group. This is the first study to suggest the one-month strategy is as safe and effective as the standard year-long regimen of dual clot-preventing therapy for people with AFib treated with a stent. Note: ...

Research Highlights: Successful catheter ablation resulted in a low risk of stroke associated with atrial fibrillation (AFib), a type of irregular heart rhythm, according to an international study. Researchers said these findings may suggest that ongoing blood-thinning medication may not be needed after an ablation procedure. While catheter ablation is known to reduce the occurrence of AFib, it’s been unclear if it also reduces the increased stroke risk associated with the AFib.  Note: This ...

Research Highlights: Earlier blood transfusion after major surgery – when hemoglobin was below 10 g/dL rather than beow 7 g/dl - did not affect the risk of severe complications, such as death, heart attack, need for a heart procedure, kidney failure or stroke. However, the timing of the blood transfusion may be associated with a lower risk of irregular heartbeat and heart failure among people with heart disease, according to a new study of U.S. military veterans. Note: This trial is simultaneously published today as a full manuscript in the peer-reviewed scientific journal JAMA. Embargoed ...

Texas Tech University researchers have received grant funding totaling roughly $12.25 million over five years from the National Science Foundation (NSF) to explore infrastructure necessary for large-scale computing that uses multiple energy sources. The REmotely-managed Power-Aware Computing Systems and Services (REPACSS) project will build an advanced system prototype and develop and test tools for automation, remote data control, and scientific workflow management. REPACSS will be housed at the ...

Research Highlights: Adults with atrial fibrillation and obesity/overweight (but no diabetes) who took the diabetes medication metformin after a rhythm correction procedure were more likely to stay free of AFib episodes for a year. Weight loss was not thought to be the main reason metformin helped, since there was only a modest weight change among those taking the medication. Future studies may compare the impact of metformin with other diabetes medications in treating adults with obesity and AFib.  Note: The study featured in this news release is a research abstract. Abstracts presented at American Heart Association’s scientific meetings are not ...

DALLAS, Nov. 10, 2025 — Despite major advances in care, nearly half of U.S. adults live with some form of cardiovascular disease or stroke, according to the American Heart Association®, a relentless force changing the future of health for everyone everywhere. To close this gap, innovative health solutions must reach people where they live, work and play. At its Scientific Sessions 2025, the Association recognized two pioneering companies whose health technologies could help do just that. Houston-based PolyVascular was named the overall winner of the American Heart Association’s annual Health Tech Competition, earning top honors in the business category. ...

Research Highlights: During the 6 months after treatment to restore a normal heart rhythm, adults with atrial fibrillation (AFib) who were randomly assigned to drink coffee every day were 39% less likely to have a recurrence of AFib compared to participants assigned to not have any coffee or other caffeinated drinks. The results of the 200-person trial may challenge the common belief that caffeine may spur more abnormal heart rhythms such as AFib. Researchers say it is reasonable for health care professionals to let their AFib patients try naturally caffeinated drinks ...

Research Highlights: Adults with heart disease prescribed vitamin D in doses tailored to reach blood levels considered optimal for heart health (>40-80 ng/mL) had a reduced risk of heart attack by more than half (52%) compared to those who did not receive monitoring of vitamin D levels. 85% of all study participants had vitamin D levels below 40 ng/mL at enrollment, and nearly 52% of people in the treatment group needed to take more than 5,000 IU of vitamin D each day (more than six times the 800 IU daily value established by the FDA) to reach target blood ...

A team led by University of Pittsburgh’s Graham Hatfull has developed a method to construct bacteriophages with entirely synthetic genetic material, allowing researchers to add and subtract genes at will. The findings open the field to new pathways for understanding how these bacteria-killing viruses work, and for potential therapy of bacterial infections. As phages’ secrets are revealed, researchers will be able to engineer them with genomes tailor-made to attack specific bacteria, leading to new ways to combat the worsening problem of antibacterial resistance.  Contact ...

Research Highlights: For people who have experienced a heart attack or stroke, or who are at high risk of one and need further cholesterol lowering, a new daily pill may be a more convenient yet similarly effective option to injectable therapies. The oral medication, enlicitide, lowered LDL cholesterol by up to 60% and could eventually offer an option for people whose LDL levels remain above goal despite lifestyle changes and standard cholesterol medications like statins. A longer, ongoing cardiovascular outcomes study will examine whether enlicitide can reduce the risk of heart attack or stroke. Note: The study featured ...

Nancy Brady has been gratified to see the tool she and colleagues pioneered over a decade ago to measure the growth of infants’ pre-speech communication skills translated into several languages and referenced in more than 100 research papers, including a åçnew one published in the Journal of Speech, Language and Hearing Research. Brady, a professor in the University of Kansas Department of Speech-Lanuage-Hearing: Sciences & Disorders, and her now-former graduate student Olivia Boorom were among the co-authors of a new paper ...

Research Highlights: Standard care, which included medication for those eligible, was better than a promising minimally invasive procedure for people with irregular heart rhythms who had high stroke and bleeding risk. The procedure seals off a small pouch of heart tissue, where most blood clots form in people with irregular heartbeat. However, in older people, standard care, including the use of blood thinners when indicated, did a better job at prevention of stroke, blood clots, cardiovascular or unexplained death ...

Cyanobacteria, commonly known as blue-green algae, are found almost everywhere in the world—from hot springs to arctic ice to antioxidant smoothies. Part of their extreme adaptability lies within a unique light-harvesting structure called the phycobilisome. These modular antennae both collect energy from sunlight, and adapt to changing light levels in order to provide a sort of sunscreen for the bacteria.  One important way that phycobilisomes adapt involves an accessory protein to both sense and protect against too much light. ...

Websites produced for COP conferences emit up to seven times more carbon than average internet pages, new research suggests. Ahead of this year’s United Nations climate summit, COP30, researchers have revealed a sharp increase in the carbon emissions generated by the conference’s websites over time. Analysis indicates that between 1995 – when the first Conference of the Parties (COP) was held – and 2024, average emissions from COP conference websites have risen by more than 13,000%. While ...

NIMS has been developing chemical sensors as a key component of the artificial olfaction technology (olfactory sensors), with the aim of putting this technology into practical use. In this study, explainable AI (XAI) was used to reveal how chemical sensors discriminate among various odorant molecules. The findings may help guide the selection of receptor materials for developing high-performance chemical sensors capable of detecting odorant molecules. The achievement is expected not only to improve the performance of artificial olfaction but also to advance understanding of human olfactory mechanisms. This ...

New research from Intermountain Health in Salt Lake City finds that patients diagnosed with peripheral arterial disease (PAD) who also have atrial fibrillation (AFib) face a significantly higher risk of major adverse cardiovascular events (MACE). The Intermountain study analyzed long-term data of Intermountain Health patients with PAD and found that AFib was present in approximately one in four PAD patients, making this combination far more common than previously recognized. More importantly, Intermountain researchers found the presence of AFib nearly doubles the risk of major adverse cardiovascular events in patients compared to PAD alone. Irregular heart rhythms are called arrhythmias. ...

While some risk factors for cancer can be mitigated through lifestyle choices such as diet or exercise, aging is not one of them. In the case of pancreatic cancer, it also can limit treatment options if a patient is too frail to be safely treated with surgery or other alternatives. Scientists at the NCI-Designated Cancer Center at Sanford Burnham Prebys Medical Discovery Institute would like to expand options for these patients with personalized treatments. Many stand to benefit from a therapeutic strategy that factors in age. The average age of a patient diagnosed with pancreatic cancer is 70, and nearly two-thirds of cases are in people over the age of ...

A psychedelic found in mushrooms is emerging as a potential treatment for alcohol use disorders. This possibility is due to a compound the body converts the psychedelic into called psilocin, but psilocin’s mechanisms remain unclear. Researchers, led by Sarah Magee and Melissa Herman at University of North Carolina at Chapel Hill, explored whether psilocin targets neurons in the central amygdala involved in emotional processing and stress to alter alcohol use in their JNeurosci paper. Herman emphasizes that ...

In a new JNeurosci paper, Sarah Jessen and colleagues, from the University of Lübeck, explored how infants track their mothers’ voices compared to unfamiliar voices. The researchers also explored whether this vocal processing affects how babies process new faces.  Brain recordings of babies around 7 months old showed that they were far more attuned to the voices of their mothers than strangers. Additionally, neural tracking of unfamiliar faces was stronger when babies heard a stranger’s voice compared to their mother’s voice at the same time. Whether a face ...

In a new JNeurosci paper, Kahori Kita and colleagues at Johns Hopkins University explored how people switch between intuitive motor skills they know and newly learned movement patterns.  Study volunteers frequently made errors switching between more innate movements and new ones. These errors were largely because people persistently stuck to the movement patterns they used before the switch. Notes Kita, “People made similar errors when switching from the intuitive to the new skill, as when switching from the new skill to the intuitive one.” A second group of people learned two new movement-based skills. It was initially even more difficult for these ...

A new native bee species with tiny devil-like “horns” named Megachile (Hackeriapis) lucifer has been discovered in Western Australia’s Goldfields, highlighting how much remains unknown about Australia’s native pollinators. The striking new bee was found during surveys of a critically endangered wildflower Marianthus aquilonarius that grows only in the Bremer Range region, which is between the towns of Norseman and Hyden. Lead author Curtin Adjunct Research Fellow Dr Kit Prendergast, from the Curtin School of Molecular and Life Sciences, said the female bee’s unusual ...

ST. LOUIS, MO, November 10, 2025 - A new collaborative research team of plant scientists led by Ru Zhang, PhD, associate member, Danforth Plant Science Center has been awarded new funding from the National Science Foundation to investigate how photosynthetic cells retain “heat stress memory” (HSM), a key adaptive mechanism that could help future crops withstand intense and frequent heat waves.  Photosynthesis, the process by which plants convert sunlight into energy, is the key driver of plant growth ...

Researchers at the University of California San Diego School of Medicine have developed a new approach for identifying individuals with skin cancer that combines genetic ancestry, lifestyle and social determinants of health using a machine learning model. Their model, more accurate than existing approaches, also helped the researchers better characterize disparities in skin cancer risk and outcomes. Skin cancer is among the most common cancers in the United States, with more than 9,500 new cases diagnosed every day and approximately ...
