The world’s fastest single-shot 2D imaging technique films ultrafast dynamics in flames

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.

Warning labels from fact checkers work — even if you don’t trust them

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' ...

From wild relatives to super tomatoes: Unearthing new genetic potential

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.

New fuel cell catalyst enhances longevity and reduces cost for Fuel Cell Electric Vehicles (FCEVs)

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.

Brigham-led clinical trial finds finerenone reduces worsening heart failure and cardiovascular death

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.

Accuracy verification methodology for CGH used for testing ultra-large aperture mirrors

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.

Wearable heart monitor increases diagnosis of irregular heart rhythm

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.

Optimizing electrical stimulation therapies with machine learning

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.

Promising treatment for incurable prostate cancer

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.
