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 / 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 ...
