A nanotechnology-based drug delivery system developed at UVA Health to save patients from repeated surgeries has proved to have unexpectedly long-lasting benefits in lab tests – a promising sign for its potential to help human patients. The approach would allow surgeons to apply a paste of nanoparticles containing hydrogel on transplanted veins to prevent the formation [...]
Japanese scientists detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission. NASA’s OSIRIS-REx mission brought back 121.6 grams of asteroid Bennu, unveiling nitrogen-rich organic matter, including DNA’s essential bases. Scientists found differences between Bennu’s chemistry and that of meteorites like Ryugu, suggesting diverse cosmic conditions shaped their molecular [...]
Scientists have pioneered a groundbreaking method to combat snake venom using newly designed proteins, offering hope for more effective, accessible, and affordable antivenom solutions. By utilizing advanced computational techniques and deep learning, this innovative approach has already shown promising results in neutralizing deadly toxins, potentially transforming antivenom development, and offering new strategies for tackling [...]
A pioneering study has unveiled the Au-HN-1 nanosystem, a cutting-edge approach that promises to transform the diagnosis and treatment of tongue squamous cell carcinoma (TSCC). By harnessing gold nanoparticles coupled with the HN-1 peptide, this innovative system targets TSCC cells with unprecedented precision, offering enhanced photothermal therapy (PTT) and dual-mode imaging capabilities. With the [...]
A landmark global survey conducted across 68 countries has found that public trust in scientists remains robust, with significant support for their active involvement in societal and political matters. The study highlights the public’s demand for science to prioritize issues like public health and energy solutions over defense technologies, pointing to a potential misalignment [...]
In a recent study published in the journal Science Advances, researchers investigated the impact of microplastics on blood flow and neurobehavioral functions in mice. Using advanced imaging techniques, they observed that microplastics obstruct cerebral blood vessels by causing individual immune cells to become trapped in capillaries. The findings revealed a novel mechanism through which microplastics indirectly disrupt [...]
A new mathematical model enhances the evaluation of AI identification risks, offering a scalable solution to balance technological benefits with privacy protection. AI tools are increasingly used to track and monitor people both online and in person, but their effectiveness carries significant risks. To address this, computer scientists from the Oxford Internet Institute, Imperial College [...]
Permafrost is a fascinating yet alarming natural phenomenon. It refers to ground that remains frozen for at least two consecutive years. Mostly found in polar regions like Siberia, Alaska, and Canada, permafrost plays a critical role in the Earth's climate system. Imagine the ground as a giant freezer, preserving ancient organic materials for thousands [...]
A survey led by researchers from the Center for Quantitative Health at Massachusetts General Hospital and Harvard Medical School has analyzed the association between self-reported social media use and irritability among US adults. Frequent social media use, especially among active posters, was correlated with higher levels of irritability. Existing studies on social media and mental [...]
Protein found in Sydney rock oysters’ haemolymph can kill bacteria and boost some antibiotics’ effectiveness, scientists discover An antimicrobial protein found in the blood of an Australian oyster could help in the fight against superbugs, new research suggests. Australian scientists have discovered that a protein found in the haemolymph – the equivalent of blood [...]
