Phys.org / A better way to detect off-target genome changes from base editors
Scientists and physicians can better assess precision genome editing technology using a new method made public today by St. Jude Children's Research Hospital. Significant amounts of time and resources spent improving CRISPR ...
Phys.org / Galactic globular cluster loses stars through tidal stripping, observations reveal
Using the Anglo-Australian Telescope (AAT), astronomers have observed a nearby galactic globular cluster known as NGC 6569. Results of the observational campaign, published December 22 on the arXiv preprint server, indicate ...
Phys.org / Evidence of upright walking found in 7-million-year-old Sahelanthropus fossils
In recent decades, scientists have debated whether a seven-million-year-old fossil was bipedal—a trait that would make it the oldest human ancestor. A new analysis by a team of anthropologists offers powerful evidence that ...
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 / 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 / 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 / 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 / Astronomers measure both mass and distance of a rogue planet for the first time
While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets seem to have been knocked out of their orbits, floating through space free of any particular gravitational ...
Phys.org / Chess960's random setups still favor white, new study reveals
Chess is a relatively simple game to learn but a very difficult one to master. Because the starting positions of the pieces are fixed, top players have relied on memorizing the "best" opening moves, which can sometimes result ...
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 / How juvenile lobsters fall into a deadly natural trap in the Florida Keys
In the shallow waters of the Florida Keys, juvenile Caribbean spiny lobsters are unwittingly meeting their doom by stumbling into naturally occurring ecological traps, according to a new study published in the Proceedings ...
