Plasma-activated water tests show concentration matters for effective bacterial disinfection
In a study published in npj Clean Water, researchers from EPFL investigated how Escherichia coli responds to different concentrations of plasma-activated water (PAW) under nutrient-rich conditions. The team combined conventional colony-forming unit (CFU) counting with nanomotion sensing, a techn...
Ultrafast X-rays reveal how the light-responsive molecular switch azobenzene changes shape
Azobenzene is one of the best-known molecules that can be switched between two forms by light. However, the question of how the molecule moves in the first few picoseconds (trillionths of a second) after it absorbs light has remained unresolved for nearly 50 years.
Why a food poisoning bacterium can cause severe wound infections
The toxin NheABC, produced by Bacillus cereus, is particularly active in the pH conditions found in open wounds. Researchers at Umeå University found that the toxin damages both cell membranes and mitochondria and helps the bacterium establish infection in wounded tissue.
NASA Astronaut Christina Koch to Join NFL Fans in Philadelphia
As part of NASA’s ongoing Inspiration Tour, NASA astronaut Christina Koch will highlight America’s strengths in space exploration and aeronautics innovation at the Philadelphia Eagles vs. Los Angeles Rams game in Philadelphia on Sunday, Oct. 4.
Motivation matters more than working memory for improving student math skills, study finds
Why do some students become ever better at mathematics, while others plateau? Many people may think that mathematics is primarily about cognitive skills. A new study from the Norwegian University of Science and Technology (NTNU) provides a more nuanced view.

Heading Home: NASA’s SpaceX Crew-12 Concludes Station Science Mission
NASA’s SpaceX Crew-12 mission is ending, with the crew scheduled to return in early October.
Small changes can have a big impact on sustainability transitions
In her dissertation, Hanna Entsalo examines how public policies, such as policy strategies and legislation, influence transitions toward the circular economy and sustainability. Entsalo works as a researcher in the Circular Economy Solutions Unit at the Finnish Environment Institute. Her work f...
Black holes may grow quietly alongside galaxies even without violent mergers
Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 "bulgeless" galaxies—systems with little or no central stellar bulge. Their paper, published in Monthly Notices of the Royal ...
NASA’s DAVINCI Probe Can Stand the Heat
The engineering development unit for NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) probe is photographed prior to a major thermal evaluation.
Scientists zero in on tiny particles to improve weather and air quality forecasts
Aerosols are small particles suspended in our atmosphere. They come in many flavors: Wildfire smoke, pollen, desert dust, sea salt lofted by powerful storms, volcanic sulfates and emissions from engines and industrial processes are all examples.
How does interdisciplinary collaboration work in practice? Three takeaways for teachers
When we speak with Luyao Huang, her Ph. D. project at Leiden University is in full swing.

National Science Foundation Diverted $1.4 Billion in Science Funds Mandated by Congress
The move, affecting about one-fifth of the National Science Foundation’s primary research budget, is the latest sign of how the White House is asserting more control over grants.
Mirror-image crystals reverse the direction of light-driven currents
The circular photogalvanic effect (CPGE), a phenomenon that generates helicity-dependent photocurrents in noncentrosymmetric materials, can originate purely from a crystal's internal structure without a contribution from the surface, a study from Science Tokyo reveals.
Forestry experts author national guidance on disaster preparedness
John Daigle, professor of forest recreation management at the University of Maine, co-authored the first paper in a series designed to help communities nationwide prepare for future natural disasters and other extreme weather events.
New algorithm makes maps of gene activity easier to compare while preserving cell-level detail
Spatial transcriptomics can reveal where thousands of genes are active across a tissue, creating molecular maps at single-cell resolution. But comparing two such maps is difficult: thin slices of tissue may be rotated, stretched or otherwise distorted, so equivalent regions do not automatically ...

Animals may have evolved vastly earlier than fossil evidence suggests
The earliest animals may have evolved hundreds of millions of years before their first unmistakable fossils appear in the fossil record, according to a new study led by the University of Oxford. The findings, published in Science Advances, suggest animals may have originated deep in the Neoprote...
Physicists who uncovered the first particle accelerator were honored with a Nobel Prize 75 years ago
While scientists are known for their dedication to their research, crawling on the floor to avoid electrocution for the sake of a measurement seems a little excessive. But this is what British physicist John Cockcroft and Irish physicist Ernest T. S.
Animals may have evolved 200 million years earlier than previously thought, new study suggests
After using a technique called molecular clock analysis, researchers have proposed that the origin of animals could be 200 million years earlier than thought.
How much are the world's oceans warming? New method reveals double-digit percentage gaps from climate models
The world's oceans behave like a thermometer: As the water warms, it expands and sea levels rise. Geodesy researchers at the University of Bonn are able to measure this and determine how much the oceans are warming. For individual ocean basins, their method has revealed significant deviations f...
