Phys.org / Cornerstone model of evolutionary biology built on math flaw, study argues
New research is significantly revising a widely cited evolutionary model, the Inhibitory Cascade Mode (ICM). Benjamin Auerbach, professor in the Department of Ecology and Evolutionary Biology at the University of Tennessee, ...
Phys.org / Cells under stress: How a chemotherapy drug damages RNA
The integrity of DNA and RNA is essential for every cell. DNA contains the genetic information for proteins, while RNA serves as a working copy of individual genes and is required for the synthesis of proteins. Unlike DNA ...
Phys.org / How systems science helps keep my flower delivery costs low
When you go out to run errands on the weekend, you're on a "tour" as defined by human mobility researchers. Same if you book a guided tour of a famous city or take a trip on a cruise boat that reaches multiple ports. A characteristic ...
Phys.org / Silicon quantum computer performs logical operations for the first time
Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based ...
Phys.org / Ancient predator species discovered in South Africa challenges what we know about gorgonopsians
In a study published in The Anatomical Record, researchers have identified a new species of large-bodied gorgonopsian from the middle Permian. The discovery pushed back the known origins of when these apex predators began ...
Phys.org / Tasmanian tiger lives on in Arnhem Land rock art
The striped dog-like marsupial we know as the Tasmanian tiger has long been surrounded by mystery, and the subject of scientific curiosity. Now, newly discovered rock art depicting Tasmanian tigers and Tasmanian devils in ...
Phys.org / Wildlife-friendly landscapes dramatically boost biodiversity in fragmented forests, research reveals
A new study has revealed that improving the landscapes surrounding forest remnants can dramatically increase their ability to retain bird species—even when the forest fragments themselves are small or isolated. For decades, ...
Phys.org / Framework unifies the classical and quantum Mpemba effects
Physicists have developed a new theoretical framework which unifies a wide array of seemingly unrelated "Mpemba effects": counterintuitive cases where systems driven further from equilibrium relax faster than those closer ...
Phys.org / Two organs, one brain area: How fish orient themselves in the water
Using zebrafish, researchers from Osaka Metropolitan University (OMU) have identified the tegmentum region in the fish midbrain as the area where light input from both the fish's eyes and the pineal organ—the "third eye"—is ...
Phys.org / Limits of protein evolution could reshape ideas about early life
The number of known proteins is infinitely small in comparison to the universe of possible proteins, which could in theory be realized. Yet these known proteins are the only major training ground for future protein design. ...
Phys.org / Measuring titanium in Apollo rock to uncover moon's early chemistry
Earth and the moon may look very different today, but they formed under similar conditions in space. In fact, a dominant hypothesis says that the early Earth was hit by a Mars-sized object, and it was this giant impact that ...
Phys.org / What's inside a masterpiece? Laser scans and AI map paint layers molecule by molecule
Paintings are far more than dabs of oil on canvas. They are complex works of art composed of multiple layers, from primer and glues to the pigments and protective varnishes applied by the artists. Being able to see into these ...
