Phys.org / How bacteria circumvent plants' immune system
How are bacterial pathogens able to effectively overcome plants' defense mechanisms? Researchers working with Professor Şuayb Üstün at Ruhr University Bochum, Germany, have found a surprising answer to this question: The ...
Phys.org / Rare ribosome tweak in E. coli reveals possible antibiotic target
Storing genetic material as DNA or RNA is all well and good for life on Earth, but it would be entirely pointless if we couldn't do anything with it. To use our genetic blueprints, all organisms need to translate the message ...
Phys.org / Why did Clovis toolmakers choose difficult quartz crystal? New study offers clues
Quartz crystals are difficult to knap due to size, hardness, and crystalline structure, making them a "low-quality" raw material. However, the Clovis people of North America sometimes made points and other tools from this ...
Phys.org / Two blazing quasars caught waltzing into a merger
Astronomers, using the Atacama Large Millimeter/submillimeter Array (ALMA), have confirmed the existence of a close quasar pair housed in a pair of merging galaxies seen when the universe was less than a billion years old, ...
Phys.org / This new tool makes AI's role in student writing visible
Generative artificial intelligence (AI) has transformed college writing. As paper drafts are increasingly co-written with AI, professors are left wondering not whether students are using AI, but how. A 2025 AI in Education ...
Phys.org / AI-enhanced microscopy produces crisp, real-time video inside live cells
Using artificial intelligence, engineers at the University of California San Diego have developed a new way to watch the inner workings of living cells in real time. The process both captures images that are twice as sharp ...
Phys.org / Extreme stability in ultrafast nanomagnetism aids the development of faster data storage
For the first time, researchers have mapped how the boundaries of magnetic nanostructures behave on extremely short timescales. The work of physicist Johan Mentink of Radboud University shows that these boundaries are much ...
Phys.org / Studying the emergence of leaders in moving crowds of pedestrians
When humans are moving as a crowd, their movements tend to be highly coordinated, similarly to the collective motions of bird flocks or other groups of animals. These group behaviors can limit collisions in dynamic environments, ...
Phys.org / More activity means less response in active materials
For some time, researchers have assumed that solid materials could gain more useful properties by making their microscopic components more active. Now, a team led by Jack Binysh at the University of Amsterdam has found that ...
Phys.org / Before dinosaurs vanished, a hamster-sized mammal was already shaping what survived next on the Pacific Coast
Mammals and dinosaurs coexisted on Earth until a catastrophic event 66 million years ago killed 75% of life on the planet. Despite the devastation, some animals survived, including rodent-like mammals in the Cimolodon genus. ...
Phys.org / Magnet with near-zero external field could reshape future electronics
An international research team led by DTU has developed a new magnetic material that features a stable internal magnetic structure, almost no external magnetic field, and retains these properties above room temperature. These ...
Phys.org / When the rain comes, some NYC subway riders stay home. Scientists are now mapping exactly who, and where
On a sweltering August afternoon or in the teeth of a winter storm, New York City subway riders make a quiet calculation: Is the trip worth it? A new study published in npj Sustainable Mobility and Transport takes a detailed ...
