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 / 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 ...
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 / 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.
