We need to consider alternatives to dark matter that better explain cosmological observations
Do constants of nature—the numbers that determine how things behave, like the speed of light—change over time as the universe expands? Does light get a little tired traveling vast cosmic distances? It was believed that dark matter and dark energy.....»»
Observations provide crucial insights into the nature of a white dwarf–brown dwarf binary
Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September 10 on the preprint s.....»»
Arctic warming may fuel ice formation in clouds, observations suggest
The Arctic frequently experiences temperatures that support the formation of mixed-phase clouds that contain supercooled liquid droplets and ice crystals. The composition of such clouds plays a crucial role in the region's energy balance and climate.....»»
Can toddlers help explain the origins of our bias for wealth?
Income and wealth inequality in the U.S. remain near all-time highs. Analysts say this disparity is a "major issue of our time." Experts have spotlighted deep policy failures fueling the problem and helpful economic fixes to alleviate the suffering......»»
Researchers spot largest black hole jets ever discovered
The jets are 140 times larger than the Milky Way. Enlarge / Artist's conception of a dark matter filament containing a galaxy with large jets. (Caltech noted that some details of this image were created using AI.) (credit: Martij.....»»
LHC experiments observe quantum entanglement at the highest energy yet
Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are. This mind-bend.....»»
Tracking plasma progression in a picosecond: Physicists develop ultra-fast laser method to study high-density plasmas
In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative term—the metal is nearly 200,000 degrees Fahrenheit. With the short.....»»
Second-gen Starlink satellites leak 30 times more radio interference, threatening astronomical observations
Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations......»»
Reinventing the clock: NASA"s new tech for space timekeeping
Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise timing signals from satellite.....»»

Students prefer teacher feedback over AI feedback, research finds
Feedback plays a crucial role in learning, helping individuals to understand and improve their performance, yet globally large and diverse student populations often mean that providing timely and personalized observations can be a challenge......»»
Nuclear theorists turn to supercomputers to map out matter"s building blocks in 3D
Deep inside what we perceive as solid matter, the landscape is anything but stationary. The interior of the building blocks of the atom's nucleus—particles called hadrons that a high school student would recognize as protons and neutrons—are made.....»»
Pollen affects cloud formation and precipitation patterns, researchers find
Ground-based and satellite observations in the United States show that increased pollen concentrations in spring lead to more cloud ice and more precipitation—even at temperatures between minus 15 and minus 25 degrees Celsius......»»
Black hole pairs may unveil new particles
In a paper published in Physical Review Letters this week, physicists from Amsterdam and Copenhagen argue that close observations of merging black hole pairs may unveil information about potential new particles. The research combines several new disc.....»»
Portugal battles ferocious wildfires as toll rises to seven
Thousands of firefighters on Tuesday battled wildfires in Portugal that have killed seven people and burnt more land in a matter of days than the rest of the summer combined......»»
