Phys.org / Curiosity Mars rover discovers field of honeycomb textures
As NASA's Curiosity rover recently began climbing a Martian valley nicknamed "Valle Grande," it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each about ...
Phys.org / Natural emulsion manages to stop fungus that threatens up to 80% of cocoa production
An innovative formulation based on natural compounds could become a sustainable alternative for controlling moniliasis, one of the most devastating diseases affecting cocoa in Latin America. A new study shows that emulsions ...
Phys.org / Ancient DNA reveals Ice Age humans targeted female woolly mammoths
Analyzing ancient DNA from more than 500 mammoth bones, an international team of researchers found that Ice Age humans selectively targeted female woolly mammoths. The results of the study, published in Current Biology, show ...
Medical Xpress / Rat study finds early secondhand smoke exposure can alter tooth enamel mineralization
Exposure to secondhand cigarette smoke during the first days of life can cause changes in tooth enamel mineralization without causing visible changes to the teeth. This was demonstrated in an animal model study conducted ...
Phys.org / Researchers investigate case of soft-tick borne relapsing fever in Austin area
Researchers at Baylor College of Medicine and the Texas Department of State Health Services have reported a likely case of soft tick-borne relapsing fever (STRF) in an Austin-area resident. Now, they highlight the growing ...
Medical Xpress / Immune signals may help predict responses to therapies for difficult-to-treat depression
In a new study, researchers from The University of Texas MD Anderson Cancer Center have uncovered insights that may help explain how rapid-acting antidepressants, such as ketamine and psychedelics, can reduce symptoms of ...
Tech Xplore / Hugging Face CEO calls for accountability after OpenAI hack
The chief executive of Hugging Face said Friday that developers should be held accountable if their AI models go rogue, after his startup faced a recent cyberattack by autonomous OpenAI software.
Phys.org / Scientists have found a new way molecules can cooperate at room temperature
What if glowing molecules could synchronize, much like fireflies flashing in unison? Researchers have discovered that molecules confined within tiny gold nanostructures can behave collectively, coordinating their interactions ...
Medical Xpress / Cancer drug enables kidney transplant despite severe immune incompatibility
An international research team led by the Medical University of Vienna reports on a new treatment strategy that has made kidney transplantation possible for a patient with no realistic chance of receiving a suitable donor ...
Medical Xpress / AI blood assay detects liver cancer across diverse international populations
Researchers at the Johns Hopkins Kimmel Cancer Center validated an artificial intelligence (AI)-powered blood test that accurately detected liver cancer in people from two geographically and biologically distinct populations ...
Phys.org / New theory on how six‑tonne Stonehenge rock was transported from Scotland thousands of years ago: On a glacier
Built from stones weighing between 2 and 25 tonnes (2 to 28 tons), the structure of Stonehenge demonstrates a scale of construction hard to imagine before the invention of the wheel. The mystery deepens when you consider ...
Phys.org / Surface engineering advances mitochondrial transplantation as a potential therapeutic strategy
Inside almost every cell in our bodies are tiny structures called organelles that keep us alive and functioning. Among these are many bean-shaped mitochondria, often referred to as the cell's power plants because they generate ...
