A study published in JAMA found that pulmonary vein isolation resulted in a statistically significant decrease in atrial fibrillation burden at 6 months. The procedure also showed substantial improvements in symptoms and quality of life for patients with symptomatic atrial fibrillation.
Researchers develop femtosecond laser sheet-compressed ultrafast photography (fsLS-CUP) to capture ultrafast dynamics in flames. The technique enables simultaneous imaging of soot particles and polycyclic aromatic hydrocarbons (PAHs), revealing their formation and growth in flames.
Aotearoa New Zealand's ancient species include kákápó, small wrens, bats, and freshwater limpets, not kiwi or moa. The findings result from a close examination of thousands of fossil bones and 9,000 specimens from about 20 million years ago.
A new type of gel developed by MLU chemists improves the safety and service life of lithium-ion batteries. Initial lab studies show that it also enhances battery performance, remaining stable at over five volts.
New research shows that social media fact-checking warning labels are broadly effective at reducing belief in and spreading of misinformation, even among those who distrust fact-checkers. The study found that warning labels can significantly reduce false headlines' accuracy ratings and willingness to share, regardless of participants' ...
A new eight-way tomato Multiparental advanced generation intercross (MAGIC) population has been developed to unlock diverse traits from wild tomato species. The population combines diverse alleles from wild and weedy tomatoes, revealing 6,488 high-quality SNPs and associations with traits such as fruit size and pigmentation.
The FINEARTS-HF trial demonstrates finerenone's benefits in reducing worsening heart failure events and mortality in patients with mildly reduced or preserved ejection fraction. Finerenone significantly reduces total worsening HF events compared to placebo, but shows non-significant reductions in cardiovascular death.
A University of Dundee study has used machine learning to analyze health records of heart failure patients and identify alternative treatment plans that could improve their welfare. The pilot project aims to tailor treatment for each patient, ensuring they receive optimized care with the potential to improve quality of life.
Researchers at Heidelberg University developed an AI-supported method to map mosquito populations by analyzing satellite and street view images. This approach helps assess environmental conditions favoring Aedes aegypti presence, enabling targeted disease control measures.
Researchers at Daegu Gyeongbuk Institute of Science and Technology developed a new fuel cell catalyst made from platinum and magnesium, significantly improving efficiency and longevity. The catalyst surpasses US Department of Energy's 2025 performance targets, demonstrating its high efficiency and long-term stability.
Researchers have developed a new algorithm for fully dynamic all-pairs shortest paths in the Massively Parallel Computation model, achieving lower round complexity and memory usage compared to existing static algorithms. The proposed algorithm combines graph and algebraic methods to reduce computational overhead.
A nationwide study in Sweden reveals that short-term exposures to lower air temperature and cold spells are associated with an increased risk of myocardial infarction hospitalization after two-six days. Researchers found that this delay in hospitalizations suggests a delayed onset of cold-related impacts on MI risk.
A randomized, placebo-controlled trial found finerenone improved outcomes in patients with heart failure and mildly reduced or preserved ejection fraction. The drug also showed benefits regardless of the ejection fraction and even in patients on other approved therapies.
A phase III trial found that asundexian was inferior to apixaban in preventing stroke and systemic embolism in high-risk patients with atrial fibrillation. The trial also showed lower bleeding rates with asundexian, but this finding needs to be put into context with the stroke findings.
Vultures, like young humans, explore new sites and socialize frequently when they're young. However, as they age from around 10 years old, they scale back on socializing and prefer to stay at the same roosting site, similar to humans who tend to stay home.
Researchers have developed a new accuracy verification methodology for ultra-large aperture mirrors using computer-generated hologram (CGH), achieving nanometer-level accuracy. The method uses an equivalent element to test the mirror's surface shape accuracy, overcoming aperture limitations and enabling reliable testing.
A large study found that wearable heart monitors increased diagnoses of atrial fibrillation by 52% compared to usual care. However, it did not lead to a significant reduction in hospitalizations due to stroke. The study's findings provide inconclusive data on the effectiveness of screening for atrial fibrillation in reducing stroke risk.
A recent study identifies key weather patterns contributing to typhoon clustering, including the Monsoon Trough pattern and other atmospheric factors. This clustering of tropical cyclones can significantly increase disaster risks and cause extensive damage.
A recent genomics study of prairie chickens in five states has found evidence of hybridization between the two species, with no clear indication of genetic problems. The study suggests that these species may belong to the same species and challenges wildlife management nationwide.
A novel Group Scene Graph Generation method is proposed to understand team sports videos from an athlete's perspective. The approach constructs a hierarchical relation network to establish intra-team and inter-team relationship features, significantly improving performance over baselines.
The EPIC-CAD trial shows that edoxaban monotherapy significantly reduces the risk of primary endpoint, major bleeding, and major ischaemic events compared to dual antithrombotic therapy in patients with high-risk atrial fibrillation and stable coronary artery disease.
A recent study published in The Journal of Raptor Research found that Ferruginous Hawk populations are increasing in California, contrary to declining trends in other grassland bird species. Citizen science data analysis revealed a significant decrease in habitat quality yet an increase in hawk abundance across California.
Red blood cells undergo a regulated process of removal to prevent premature ageing and potential health issues. The study highlights the role of proteins in regulating this process, paving the way for novel therapeutics and early diagnostics for anaemia.
Researchers at Duke University have developed a computer model that simulates nerve responses to electrical stimulation, enabling the efficient design of more effective and targeted neuromodulation therapies. The new tool, called S-MF, runs thousands of times faster than current industry standards without sacrificing accuracy or detail.
Researchers from National Cancer Centre Singapore have successfully used exosomes to target squamous cell cancer tumours resistant to EGFR-TKIs. The study found that exosomes carrying a specific protein can increase sensitivity to TKIs in both lab and mouse models, providing new therapeutic solutions for patients with poor prognosis.
Researchers at Flinders University and University of South Australia have discovered a potential breakthrough in treating the most aggressive forms of prostate cancer using CDKI-73, a novel drug inhibitor. The study found that CDKI-73 effectively blocks the growth of prostate cancer cells while sparing normal cells.
