Phys.org / New self-assembling polymers proven to be effective at gene delivery
A collaboration of scientists at the University of Manchester and the University of Birmingham has explored a more effective and less toxic way of delivering genetic material into cells, a challenge central to areas such ...
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 / More than two species? Scientists challenge taxonomy of two-toed sloths in Amazonia
A new study by scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) has revealed significant cryptic diversity within two-toed sloths (Choloepus) in Amazonia, challenging the long-established ...
Phys.org / A host of positive 'tipping points' can regenerate nature
A host of positive "tipping points" can spark rapid nature recovery, a leading expert says. Action to protect and restore nature must accelerate radically to meet global goals for 2030 and beyond. Writing in the journal Nature ...
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 / Improving animal welfare in the lab: AI helps better detect pain
At first glance, the white plastic box with a bright orange floor looks like something for storing children's toys. However, the box isn't used to store Lego bricks; it contains real mice—with the aim of minimizing their ...
Phys.org / Tandem superflare observations reveal origin of the stellar Fe Kα line
The Fe Kα line, or iron Kα line, is often used in astronomical research to understand the physical composition of astronomical objects. This line is produced when a K-shell electron of an iron ion in the photosphere—the gas ...
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 ...
