Phys.org / Scientists have uncovered evidence of Ireland's largest prehistoric hillfort settlement
In a recent study published in Antiquity, Dr. Dirk Brandherm and his colleagues identified more than 600 suspected house platforms in the Brusselstown Ring hillfort, making it the largest nucleated settlement ever discovered ...
Phys.org / Origins of THC, CBD and CBC in cannabis revealed
Where do the well-known cannabis compounds THC, CBD and CBC come from? Researchers at Wageningen University & Research have experimentally demonstrated for the first time how cannabis acquired the ability to produce these ...
Phys.org / Nanoparticle therapy reprograms tumor immune cells to attack cancer from within
Within tumors in the human body, there are immune cells (macrophages) capable of fighting cancer, but they have been unable to perform their roles properly due to suppression by the tumor. A KAIST research team led by Professor ...
Phys.org / First ancient herpesvirus genomes document their deep history with humans
For the first time, scientists have reconstructed the ancient genomes of human betaherpesvirus 6A and 6B (HHV-6A/B) from archaeological human remains more than two millennia old. The study, led by the University of Vienna ...
Phys.org / Two white-blooded fish, two paths: Icefish and noodlefish independently lose red blood cell function
Antarctic icefish are famous for living without red blood cells, but they are not alone. A species of needle-shaped, warm-water fish called the Asian noodlefish also lacks hemoglobin and red blood cells. Like icefish, its ...
Phys.org / Study unveils the dual nature of a young stellar object
Astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) in India and elsewhere have conducted a long-term photometric and spectroscopic study of a young stellar object known as V1180 Cassiopeiae. ...
Phys.org / Wood-derived chemicals offer safer alternative for thermal receipt paper coatings
Every day, millions of people use thermal paper without thinking about it. Receipts, shipping labels, tickets, and medical records all rely on heat‑sensitive coatings to make text appear. More specifically, heat triggers ...
Phys.org / Einstein Probe detects an X-ray flare from nearby star
Using the Einstein Probe (EP), astronomers have detected a new X-ray transient event, which turned out to be an X-ray flare from the star PM J23221-0301 located about 150 light years away. The finding was reported in a research ...
Phys.org / How a single 2003 heat wave triggered lasting upheaval in the North Atlantic
The ecology of the North Atlantic is constantly changing. Sometimes it changes abruptly. Extreme events are one driver of such sudden changes. A team of researchers has discovered that a single, large-scale heat wave has ...
Phys.org / Physicists repair flaw of established quantum resource theorem
Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the past decades, researchers have introduced several new quantum information frameworks and theories ...
Phys.org / Flowering plant origins: Dosage-sensitive genes suggest no whole-genome duplications in ancestral angiosperm
Angiosperms, also known as flowering plants, represent the most diverse group of seed plants, and their origin and evolution have long been a central question in plant evolutionary biology. Whole-genome duplication (WGD), ...
Phys.org / Bacteria reveal second 'shutdown mode' for surviving antibiotic treatment
A new study reveals that bacteria can survive antibiotic treatment through two fundamentally different "shutdown modes," not just the classic idea of dormancy. The paper is published in the journal Science Advances.
