Phys.org / Ultrasound-activated 'nanoagents' kill superbugs hiding in biofilms
Scientists have designed nanoagents that act like smart drug-delivery capsules—carrying an antibiotic deep into bacterial infection sites and releasing it only when activated by gentle ultrasound. Delivering antibiotics ...
Phys.org / Modern twist on wildfire management methods has a bonus feature that protects water supplies
Wildfires are among the most economically costly natural disasters and are becoming more severe and frequent due to global warming. The United Nations Office for Disaster Risk Reduction estimates that global damage from wildfires ...
Phys.org / Tech upgrade reveals even finer transcription detail inside cells
In 2021, a technology developed at the University of Michigan, called Seq-Scope, revolutionized the ability to map gene activity within intact tissue at microscopic resolution, enabling researchers to measure all expressed ...
Medical Xpress / Sun smart kids have 50% fewer moles and a lower melanoma risk
A long-running Queensland study has found children today are developing significantly fewer moles than kids 25 years ago, with predictions of a major reduction in future melanoma risk. The Brisbane Twin Nevus Study, led by ...
Phys.org / Scared of spiders? The real horror story is a world without them
Members of the arachnid class—think spiders, scorpions and harvestmen (daddy long legs)—are often the targets of revulsion, disgust and fear. Yet, they are crucial for ecosystems to thrive. Given the crash in worldwide ...
Phys.org / PFAS exposure greater in wet pet food, study suggests
Ehime University investigators measured 34 per- and polyfluoroalkyl substances in 100 commercial dog and cat foods sold in Japan and detected PFAS across many products, with higher concentrations in fish-based foods and dry ...
Phys.org / Creating sustainable supply of declining tree species can support floodplain habitat restoration
A number of native black poplar whips—young unbranched trees—were planted at the campus near Southwell as part of a project involving NTU, the Environment Agency, Nottinghamshire Wildlife Trust, Trent Rivers Trust, Nottinghamshire ...
Tech Xplore / These are the new EVs we're most excited about in 2026
After years of experimentation and early adoption, automakers are rolling out the next generation of electric vehicles that better align with people's needs and expectations. This year, you can expect to see new EVs that ...
Tech Xplore / A more durable direct air capture approach: Electrified mineral-based system resists oxygen and humidity
Many governments and businesses worldwide have been trying to devise effective initiatives aimed at mitigating climate change and global warming. So far, their primary focus has been to reduce the emission of carbon dioxide ...
Medical Xpress / Beating, 3D-printed heart model developed for surgical practice
Washington State University researchers have developed a 3D-printed model of the left side of the heart that contracts and beats, offering the chance for surgeons and medical students to rehearse important heart surgeries ...
Phys.org / Smart fluorescent molecules provide cheaper path to sharper microscopy images
Multiphoton microscopy is used in biomedical research to study cells and tissues. Today, so-called two-photon microscopy is used to study processes within cells, but the technique has limitations in terms of image resolution. ...
Phys.org / Sting in the tail of scorpion venom accelerates blood clotting, could help save lives
A University of Queensland study has shown that a deadly scorpion's venom carries an extra biochemical sting that could be used to guide future medical treatments and tests. The paper is published in the journal Biochimie.
