Phys.org / Neutrality isn't a safe strategy on controversial issues, research shows
Researchers Rachel Ruttan and Katherine DeCelles of the University of Toronto's Rotman School of Management are anything but neutral on neutrality. The next time you're tempted to play it safe on a hot-button topic, their ...
Phys.org / Possible 'superkilonova' exploded not once but twice
When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the universe with heavy elements such as carbon and iron. Another type of explosion—the kilonova—occurs ...
Phys.org / What's powering these mysterious, bright blue cosmic flashes? Astronomers find a clue
Among the more puzzling cosmic phenomena discovered over the past few decades are brief and very bright flashes of blue and ultraviolet light that gradually fade away, leaving behind faint X-ray and radio emissions. With ...
Phys.org / A universal law could explain how large trades change stock prices
Financial markets are often seen as chaotic and unpredictable. Every day, traders around the world buy shares and sell assets in a whirlwind of activity. It looks like a system of total randomness—but is it really?
Phys.org / 8.2 ka event triggered social transformation, not destruction, at China's Jiahu site
In a recent study, Dr. Yuchen Tan and colleagues examined the response of the North China Plain settlement of Jiahu to the abrupt climatic 8.2 ka event. They found that Jiahu not only survived but also demonstrated remarkable ...
Phys.org / A new global map uses a fleet of satellites to catch methane leaks from the energy sector
When it comes to global warming and greenhouse gases, methane is one of the bad guys. It's the second most important contributor to climate change after carbon dioxide. However, quantifying the exact amount being released ...
Phys.org / Rare brown dwarf discovered orbiting ancient star
Astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) and elsewhere report the discovery of a new brown dwarf about 60 times more massive than Jupiter. The newfound substellar object, designated TOI-7019 ...
Phys.org / A new family of barium-based crystals reveals rules for structural changes
The ultimate goal of materials scientists is to design and create materials with precise structures and tailored properties. Predictive technologies have advanced significantly with the rise of AI, yet the delicate nature ...
Phys.org / Scientists identify first non-coding gene that controls cell size
What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases. Until now, the genetic basis behind cell size has ...
Phys.org / Category '6' tropical cyclone hot spots are growing
The oceanic conditions that churn up the very strongest of hurricanes and typhoons are heating up in the North Atlantic and Western Pacific, fueled by warm water that extends well below the surface. Human-caused climate change ...
Phys.org / How owl leftovers became the perfect home for ancient baby bees
About 20,000 years ago, a family of owls lived in a cave. Sometimes, they would cough up owl pellets containing the bones of their prey, which landed on the cave floor. And, researchers have just discovered, ancient bees ...
Phys.org / Altermagnetism in RuO₂ thin films: A new magnetic material for the AI era
A research team has demonstrated that thin films of ruthenium dioxide (RuO₂) exhibit altermagnetism—the defining property of what is now recognized as the third fundamental class of magnetic materials.
