Phys.org / Trees for hotter cities: New approach can bolster community input in meeting targets
Efforts to plant more trees in cities could be boosted thanks to a new tool for planners and community groups, published by an international group of researchers. Residents, policymakers and tree officers in Cardiff, Milton ...
Phys.org / Jellyfish videos reveal why science content sparks curiosity for some viewers
It can be easy to get sucked into social media for hours on end. Funny, cartoony science videos may be especially interesting, but not to everyone, according to a recent study from the University of Georgia.
Medical Xpress / Emergency doctors are stressed out—and patient irritation plays a significant role
HBO's emergency-department drama "The Pitt" has become a smash hit in large part because it shows the deeply human toll that emergency medicine exacts on those who practice it. While researchers have long known that real-life ...
Tech Xplore / New catalyst could enable safer electrolyzers for clean hydrogen production
Hydrogen could serve as a clean alternative to fossil fuels because, when used as a fuel, it produces water vapor instead of carbon dioxide (CO2). This cleaner fuel has proved particularly promising for the creation of so-called ...
Phys.org / Tiny magnetic 'flowers' could expand how researchers image spintronic materials under stronger fields
Materials with magnetic nanostructures have a wide range of potential applications. One area is so-called spintronics, with devices that encode information in magnetic domains. These magnetic bits can be written, read and ...
Medical Xpress / Normal oxygen levels can miss severe breathlessness driven by carbon dioxide
A study led by biomedical scientist Erica Heinrich at the University of California, Riverside, highlights a critical gap in how clinicians detect and treat breathing distress (dyspnea), particularly in patients on ventilators. ...
Phys.org / New imaging method offers fresh insight into LED materials
Light Emitting Diodes (LEDs) are used in everything from household lighting and mobile phones to large display screens. Improving their efficiency could reduce energy use and enhance performance across a wide range of technologies. ...
Phys.org / Gravitational waves reveal hidden populations within black hole mergers
Since gravitational waves were first detected in 2015, instruments including LIGO, Virgo and KAGRA have picked up a steady stream of signals from colliding black holes, building a catalog that now numbers in the hundreds. ...
Phys.org / Self‑building molecular rings bring next‑generation drug delivery and smart materials closer
Rotaxanes are dumbbell-shaped mechanically interlocked molecules in which one or more ring-shaped molecules are threaded through a linear segment, known as the axle. To keep the ring from sliding off, two bulky groups, sometimes ...
Phys.org / Climate change leaves northern tree swallows more vulnerable those in the southern US
Tree swallows in the northern U.S. and Canada face the greatest risk from climate change despite responding to temperature the same way as tree swallows in the southern U.S., according to a new study led by Cornell researchers ...
Phys.org / Textbook chemistry gains blue-light upgrade to build complex drug molecules in fewer steps
In drug discovery, building complex molecules quickly is the name of the game.
Medical Xpress / Night owls eat later, choose less nutritious food, carry more belly fat and show higher metabolic risk
For generations, early to bed and early to rise was seen as the blueprint for a healthy life, and any departure from it was often considered unhealthy. Scientists, however, have discovered that whether someone is an early ...
