Phys.org / Sudden breakups of monogamous quantum couples surprise researchers
Quantum particles have a social life, of a sort. They interact and form relationships with each other, and one of the most important features of a quantum particle is whether it is an introvert—a fermion—or an extrovert—a ...
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 / 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 / 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 / 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 / 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 / Quantum spins team up to create stable, long-lived microwave signals
When quantum particles work together, they can produce signals far stronger than any one particle could generate alone. This collective phenomenon, called superradiance, is a powerful example of cooperation at the quantum ...
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 / How the 'guardian of the genome' impacts blood vessel growth
The protein p53, best known as the "guardian of the genome" for its role in preventing cancer, can affect blood vessels in different ways. However, it has not been clear how p53 can slow blood vessel growth in some cases ...
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.
Phys.org / Finding runaway stars to help map dark matter in the Milky Way
Hypervelocity stars have, since the 1920s, been an important tool that allows astronomers to study the properties of the Milky Way galaxy, such as its gravitational potential and the distribution of matter. Now astronomers ...
