Medical Xpress / Targeting key proteins in fight against ALS
Northwestern Medicine scientists have zeroed in on a cellular gatekeeper that may hold promise for treating abnormal protein accumulation in neurodegenerative diseases, according to a study published in Nature Communications. ...
Phys.org / 5,500-year-old skeleton yields oldest evidence yet of syphilis-related bacteria
Scientists have recovered a genome of Treponema pallidum—the bacterium whose subspecies today are responsible for four treponemal diseases, including syphilis—from 5,500-year-old human remains in Sabana de Bogotá, Colombia. ...
Phys.org / Social networks spanned thousands of square kilometers during the Upper Paleolithic period, study finds
Researchers from several European institutions, led by scientists from the University of Barcelona and the University of Alcalá, have demonstrated that the hunter-gatherers who inhabited the interior of the Iberian Peninsula ...
Phys.org / Accessing water on Mars: Examining the best technologies for future missions
A new study has examined how future human missions to Mars could access one of the planet's most vital resources—water. The "Martian aqua: occurrence of water and appraisal of acquisition technologies" paper, published ...
Phys.org / Copper-carrying compound targets and kills MRSA bacteria by mimicking iron
A research team at the University of Arizona College of Medicine–Tucson is developing a drug that works in combination with copper to kill bacteria, including those that cause MRSA, a type of staph infection that is resistant ...
Phys.org / Single enzyme streamlines production of all four RNA building blocks
A single enzyme that can generate all four nucleoside triphosphates, the building blocks of ribonucleic acid (RNA), has been identified by researchers at the Institute of Science Tokyo. The study was published online in the ...
Medical Xpress / A new atlas could help guide researchers studying neurological disease
Functioning brain cells need a functioning system for picking up the trash and sorting the recycling. But when the cellular sanitation machines responsible for those tasks, called lysosomes, break down or get overwhelmed, ...
Phys.org / Nash equilibria: The hidden math behind predator–prey behaviors
Animal survival depends on effective attack and defense strategies, yet how these behaviors arise remains unclear. Addressing this question, a recent study shows that predator and prey behaviors emerge naturally as stable ...
Phys.org / Stingrays inspire smarter ocean robots: The physics of fin motion
Using robotic fins, researchers at the University of California, Riverside have learned how stingrays are able to swim with impressive control. These insights could help underwater vehicles avoid disastrous ground collisions.
Phys.org / Experiment clarifies cosmic origin of rare proton-rich isotope selenium-74
Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, called p-nuclei. Led by Artemis Tsantiri, then-graduate student at the Facility for Rare Isotope Beams ...
Tech Xplore / AI is already writing almost one-third of new software code, study shows
Generative AI is reshaping software development—and fast. A new study published in Science shows that AI-assisted coding is spreading rapidly, though unevenly: in the U.S., the share of new code relying on AI rose from ...
Medical Xpress / Discovery illuminates how inflammatory bowel disease promotes colorectal cancer
A chain of immune reactions in the gut—driven by a key signaling protein and a surge of white blood cells from the bone marrow—may help explain why people with inflammatory bowel disease (IBD) have a higher risk of colorectal ...
