Medical Xpress / How to build a nutritious emergency food stockpile
A UK government watchdog has said UK homes aren't prepared for possible food supply disruptions caused by disasters like cyberattacks, power outages, disease outbreaks or extreme weather.
Phys.org / A new design for a plasma engine fuels on only thin air
Choosing an orbit for a satellite always comes with trade-offs. Very low Earth orbit (VLEO), between 100–450 km (62–280 miles), has distinct advantages. Remote-sensing cameras can take better pictures, communications and ...
Tech Xplore / Material composition of cars mapped to assess resource impact
A passenger car contains far more materials than its weight alone would suggest. Beyond the steel and aluminum are small amounts of gold, palladium and molybdenum—elements that can become highly significant when resource ...
Phys.org / Tough vehicle and construction plastics dissolve into reusable material with low-waste method
A new recycling technique could help tackle a major challenge: breaking down some of the toughest plastics without generating large amounts of waste.
Phys.org / New light-emitting nanoparticles can detect subtle chemical differences
A team of researchers from University of Toronto Engineering has created a new type of dye-sensitized nanoparticle that can detect target chemicals at very low concentrations while also distinguishing between molecules with ...
Phys.org / Room-temperature skyrmion-based synapses could pave the way for energy-efficient AI
Artificial intelligence is transforming how information is generated, processed and stored, but its rapid expansion is also driving unprecedented demand for computing power and electricity. Developing hardware that can process ...
Phys.org / Researchers invent novel eDNA membrane to advance understanding of inshore fish diversity
Monitoring marine life helps scientists track ecosystem health, improve conservation and manage fisheries. A promising approach is environmental DNA (eDNA), which refers to trace genetic material naturally released into the ...
Phys.org / Rivers may be carrying more microplastics into the world's oceans than previously thought
Microplastics are a modern environmental menace and a potential threat to human health. These tiny pieces of plastic, measuring from 1 to 5,000 micrometers, come mainly from larger plastics as well as sources such as paints ...
Medical Xpress / Reading for pleasure: Lifelong health and cognitive benefits
Reading for pleasure—from tucking into a Jane Austen classic to devouring a Heartstopper graphic novel—is linked to better mental health, greater empathy and a lower risk of dementia, say researchers.
Phys.org / Parakeets, male or female, love a good fight
In a study of monk parakeets, researchers at the University of Cincinnati and Duke University found that sex has little to no impact on who initiates fights, who is targeted or who rises in the dominance hierarchy.
Phys.org / Antibody cocktails could steer viruses into evolutionary dead ends
When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS-CoV-2 can slip past vaccines and antibody drugs before scientists fully understand what has changed. A new study from Harvard's ...
Phys.org / First confirmed Diplodocus outside North America reshapes Late Jurassic migration picture
In a discovery that challenges our understanding of dinosaur distribution during the Late Jurassic period, paleontologists have identified the first evidence of the iconic Diplodocus outside North America.
