Phys.org / Nature's puncture tools reveal shape trade-offs between piercing power and strength
Nature has invented countless types of pointy appendages, and scientists have long sought to explain what makes these structures so effective at puncturing other things. A new study models the key physical characteristics ...
Phys.org / Heat waves: Why British trees are shedding branches and dying
If you visit the Royal Botanic Gardens at Kew, on the edge of London, you will see a brightly painted skeleton of a dead oak tree. The tree, known as the climate-changed oak, succumbed in the heat wave of 2022. Instead of ...
Medical Xpress / Damaged myelin generates abnormal rhythms in the sleeping brain
Scientists have discovered how damage to the myelin sheath—the insulating layer around nerve fibers—affects brain activity during sleep.
Medical Xpress / Lower dementia risk seen with sodium-glucose cotransporter 2 in seniors 65+ with mood, psychotic disorders
Sodium-glucose cotransporter 2 (SGLT2) inhibitor use is associated with a lower risk for dementia in older adults with mood and psychotic disorders, according to a study published online June 30 in JAMA Network Open.
Phys.org / Pre-cooked seafood-based meals can absorb chemical contaminants during packaging and processing
Ready meals containing fish and seafood can expose consumers to chemical contaminants that are present in the environment or introduced during processing and packaging. A study by the Universitat Rovira i Virgili (URV) has, ...
Tech Xplore / Lowering computational costs in decentralized finance systems using AI-assisted contract development
Researchers have developed a benchmarking framework to assess whether artificial intelligence (AI) can generate decentralized finance (DeFi) smart contracts that are efficient and cost-effective, lowering computational costs, ...
Medical Xpress / How birth method and antibiotics may shape babies' gut bacteria
A new systematic review has found that both the way a baby is born and exposure to antibiotics around the time of birth could be linked to differences in the development of the infant gut microbiome. The review also found ...
Phys.org / Breathable hydrogel keeps ECG signals steady through workouts and 10 days of wear
Hydrogels are squishy, biofriendly materials made mostly of water and a bit of polymer. The Jell-O-like substance is available in the form of medical patches, sprays and glues, and can be stuck to the skin or implanted in ...
Medical Xpress / Disordered collagen may help explain hip fractures beyond bone density, X-rays reveal
Fractures of the femoral neck are not simply due to insufficient bone density. Also significant is their nanostructure—the orientation of the collagen fibers that make up bones, according to research conducted by scientists ...
Phys.org / Steering light in a flash: New chip redirects light beams in less than a trillionth of a second
Light can carry enormous amounts of information at extreme speeds, making photonic technologies promising for the development of faster communications, more powerful computing systems and more sensitive sensors. But for light ...
Phys.org / Optimizing RNA design with AI and an Ising machine: Encoding matters
RNA has emerged as one of the most promising molecules in modern medicine, enabling advances from mRNA vaccines and gene therapies to genome editing and synthetic biology. However, designing RNA molecules that reliably fold ...
Phys.org / Ocean acidification may be shrinking the brains of the world's most intelligent invertebrates
An ongoing research project exploring the effects of rising levels of oceanic CO2 on squid neurology reveals that exposure to future levels of ocean acidification could shrink their brain volume by around 50%. This severe ...
