Phys.org / Beavers thrive in river estuaries along North America's northwest coast
Beavers are widespread in estuaries and tidal wetlands in the Pacific Northwest of the United States, demonstrating that they are not restricted to rivers and streams, Gregory Hood at the Skagit River System Cooperative, ...
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 / 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 ...
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 ...
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 / How sea stars build materials that can see
When engineers think about protective materials, like those used in packaging and support, they usually think about strength, stiffness and durability. But what if those same materials could also sense their external environment?
Phys.org / Turning up the heat on cancer: Manganese ferrite nanoparticles outperform rivals
Scientists have long known that heat can be used to help fight cancer. But heating tumors and cancer cells is trickier than it sounds. Apply too much heat and patients could get hurt; apply too little or target the wrong ...
Phys.org / International team says science alone won't save coral reefs
Coral reefs are disappearing at an unprecedented rate as climate change, marine heat waves, pollution and coastal development threaten one of Earth's richest ecosystems. While scientific research has greatly advanced understanding ...
Phys.org / Simple treatment strengthens pineapple leaf fibers for sustainable composites
Pineapple leaf fiber has long been valued in parts of Southeast Asia for traditional uses, including basketry in Malaysia and Thailand and textile applications in the Philippines. Its high cellulose content and ready availability ...
Phys.org / Replacement 'climate-friendly' car refrigerant linked to rising forever chemical pollution in EU
A newer "climate-friendly" refrigerant used in car air conditioning systems may already be a significant, and possibly dominant, source of a "forever chemical" pollutant across Europe, according to a new University of Bristol-led ...
Phys.org / Romantic relationships with AI evolve in a similar way to human ones
A new study shows that relationships with artificial intelligence (AI) systems can evolve from casual conversations to bonds characterized by emotional intimacy, emotional dependence or experiences similar to a romantic breakup. ...
Phys.org / Making the 'invisible' visible: How high-speed movies could change the way scientists study disease
High-speed movies of microscopic worms may sound like a dull night at the cinema, but this advanced imaging capability could help scientists better understand how diseases begin and progress, track subtle changes in cells ...
