Phys.org / Antiviral soil compound disrupts phage infection cycle before viruses can reproduce
Bacteria also produce molecules that have an antiviral effect. Researchers from Heinrich Heine University Düsseldorf (HHU) and Jülich Research Center (FZJ) have examined the antiviral molecule daunorubicin and decoded its ...
Phys.org / Archaeologists uncover 4,000-year-old evidence of siege warfare in ancient Mesopotamia
At Kurd Qaburstan, an ancient site in the Kurdistan region of Iraq, archaeologists have uncovered the first substantial group of cuneiform administrative tablets found in the Erbil region, along with evidence of large-scale ...
Medical Xpress / Diet remodels chromatin structure and extends survival in models of glioma
An unexpected lab observation has led a team of scientists to discover how diet can influence survival in animal models of glioma, one of the most aggressive and deadly forms of brain cancer. Researchers at Baylor College ...
Phys.org / Is your dog a lefty? New 'Doginburgh' test captures paw preference
Just like left- or right-handed humans, domestic dogs have a preference for their left or right paw, a trait known as laterality. This can vary depending on the tasks they perform, which has made it difficult to create a ...
Medical Xpress / IV atorvastatin during myocardial infarction reduces myocardial damage compared to pre-infarction oral loading
Reducing the damage sustained by the heart during a myocardial infarction remains one of the major challenges in cardiology, even when the blocked coronary artery is reopened in a timely manner. Part of the myocardial injury ...
Phys.org / 'Cold insurance' for crops: Researchers unlock 'on-demand' climate resilience
Rapidly intensifying global climate instability is causing increasingly erratic temperature fluctuations. When sudden cold snaps strike during a crop's critical flowering window, they trigger irreversible pollen abortion, ...
Phys.org / Cells have a secret power line: How the nucleus gets its own private energy supply from mitochondria
For decades, biologists assumed a cell's energy simply diffused to wherever it was needed. It turns out the most important destination of all has a private delivery line.
Phys.org / Borneo's ferret badger is found nowhere else on Earth
A collaborative study has provided the most comprehensive assessment to date of the endangered Bornean ferret badger (Melogale everetti). Weighing only around one kilogram (2.2 pounds), the Bornean ferret badger is a small, ...
Phys.org / 'Black hole stars'—Webb finds strongest evidence yet
The complex puzzle known as little red dots has become more complete since their initial discovery by NASA's James Webb Space Telescope in 2022. Now a particular little red dot's spectrum is helping connect many of the pieces.
Tech Xplore / Rising from the ashes, a hidden supply of critical elements emerges
Anuja Tripathi grew up in Kanpur, India, where coal fly ash from a nearby power plant coated rooftops, windowsills and laundry hung outside to dry.
Phys.org / New iron–scandium catalyst extends carbon nanotube growth at high temperatures
Carbon nanotubes (CNTs) are among the most promising nanomaterials for future technologies because of their exceptional mechanical strength, electrical conductivity and thermal performance. However, translating these remarkable ...
Phys.org / X-rays reveal how platinum oxidizes in real time inside hydrogen devices
Electrolysers produce hydrogen. Fuel cells, in turn, generate electricity from hydrogen. Both technologies are considered key building blocks of the energy transition, offering well-established solutions for storing, transporting ...
