Phys.org / Subnational income inequality revealed: Regional successes may hold key to addressing widening gap globally
Income inequality is one of the most important measures of economic health, social justice and quality of life. More reliably trackable than wealth inequality, which was recently given a gloomy report card by the G20, income ...
Phys.org / When you're happy, your dog might look sad: Study reveals surprising twist in how people read canine emotions
When people are feeling happy, they're more likely to see other people as happy. If they're feeling down, they tend to view other people as sad. But when dealing with dogs, this well-established psychological effect ceases ...
Phys.org / Copper-64 isotope made easier: Recoil chemistry could lower medical imaging costs
The copper isotope Cu-64 plays an important role in medicine: It is used in imaging processes and also shows potential for cancer therapy. However, it does not occur naturally and must be produced artificially—a complex ...
Phys.org / Free radicals caught in the act with slow spectroscopy
Why does plastic turn brittle and paint fade when exposed to the sun for long periods? Scientists have long known that such organic photodegradation occurs due to the sun's energy generating free radicals: molecules that ...
Phys.org / Microplastics in oceans may distort carbon cycle understanding
The carbon cycle in our oceans is critical to the balance of life in ocean waters and for reducing carbon in the atmosphere, a significant process to curbing climate change or global warming.
Phys.org / AI can dramatically speed up digitizing natural history collections
A new study from UNC-Chapel Hill researchers shows that advanced artificial intelligence tools, specifically large language models (LLMs), can accurately determine the locations where plant specimens were originally collected, ...
Phys.org / X-ray spikes reveal electron beam size
While synchrotron radiation is often thought of as "stable," the electromagnetic field exhibits pronounced randomly fluctuating distributions both temporally and spatially. These fluctuations encode spatial information about ...
Phys.org / Social justice must guide global ecosystem restoration for lasting success, say researchers
Social justice must be at the heart of global restoration initiatives—and not "superficial" or "tokenistic"—if ecosystem degradation is to be addressed effectively, according to new research.
Phys.org / Astrobee: AI-guided robot navigates space station corridors with improved speed and safety
Stanford researchers have become the first to demonstrate that machine-learning control can safely guide a robot aboard the ISS, laying the groundwork for more autonomous space missions.
Phys.org / Visual system of butterflies changes with seasons, research reveals
The shift from warm summer to cool fall conditions can be stressful for many animals. Surviving each season requires a multitude of different physiological and behavioral traits that scientists are still working to understand.
Phys.org / Physicists provide key mass data for determining X-ray burst reaction rate
A research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27. These precise measurements ...
Phys.org / Yeast cell factory converts methanol into L-lactate for biodegradable plastics
Methanol is an ideal feedstock for bio-manufacturing. Converting it into lactate, a monomer for biodegradable plastic, offers a promising strategy for addressing the challenge of white pollution. However, it remains difficult ...
