Phys.org / Japan's small cities may face higher care burdens under the compact city policy
As populations decline and age across the developed world, compact city strategies, which oversee the consolidation of urban facilities and guide residents toward transit-served hubs, have become mainstream policies. Yet ...
Phys.org / Fiber-optic cables detect silent whales off Svalbard by tracking pressure waves
A 100-year-old equation and a fiber-optic cable off the coast of Svalbard led researchers to discover they could detect swimming whales—even if they were completely silent. The discovery broadens the tools biologists could ...
Tech Xplore / Seaweed-based ingredient helps turn dirt into 3D-printed walls
An ingredient that gives ice cream a creamier texture could make natural earthen materials like clay and sand easier to 3D print into durable structures, according to new research led by scientists at the University of Colorado ...
Tech Xplore / 3D photothermal design unlocks 8.5-fold higher solar evaporation for desalination and crop irrigation
The global shortage of freshwater has become a critical challenge. Conventional water treatment relies heavily on fossil fuels and associated infrastructure, which can make it unsuitable for remote and harsh regions. In contrast, ...
Phys.org / Algae microbots take aim at bladder cancer
Tiny algae-based robots guided by magnets could improve bladder cancer treatment by boosting delivery of chemotherapy drugs into tumors, researchers say.
Phys.org / Three ways climate action can be more inclusive for 1.3 billion disabled people
Imagine a global political summit that shapes the future of our planet, where one of the most populous countries in the world does not have a voice. This may seem unlikely, but currently 1.3 billion disabled people (nearly ...
Phys.org / Mathematical modeling helps advance use of magnetic particles in targeted drug-delivery systems
A Florida State University computational scientist is paving the way for future medical breakthroughs by developing mathematical models and simulations to predict the behavior of a unique drug-delivery method, which aims ...
Phys.org / Ultrafast X-rays allow researchers to 'watch' how molecules rearrange during a chemical reaction controlled by light
Since the 1980s, researchers have sought to use laser light to control chemical reactions relevant to photochemistry, catalysis and light-responsive materials. But this technique, known as coherent control, has a blind spot: ...
Medical Xpress / Emergency department testing scheme finding hundreds of unidentified HIV cases in UK
Hundreds of people in England who were unknowingly living with HIV are receiving a diagnosis and starting life-saving antiretroviral treatment, thanks to a pioneering NHS testing initiative rolled out in hospital emergency ...
Phys.org / Four new chameleon species found on Mozambique's mountaintop 'sky islands'
Tropical rainforest patches perched on isolated granite mountains in northern Mozambique have yielded four new species of sylvan chameleons, according to a new study by Prof. Krystal A. Tolley and Dr. Werner Conradie, recently ...
Phys.org / NASA's PACE mission studies smoke and fires
With the North American fire season underway, and a record number of acres already burned nationwide, NASA's Plankton, Aerosol, Cloud, and ocean Ecosystem (PACE) satellite's three instruments are observing vegetation precursors ...
Medical Xpress / Low testosterone linked to cancer risk in men
New research shows men with very low testosterone levels are at higher risk of both fatal and nonfatal cancer later in life. But while the research found men with low testosterone were 18% more likely to die of cancer years ...
