Phys.org / Epigenetic changes can be inherited without changing DNA in animals

Typically, the information encoded in DNA allows organisms to develop, function, and pass traits across generations. Yet DNA alone does not explain how genes are switched on and off in different cells and environments. This ...

Phys.org / 'Flawless on the outside, flipped within': Detecting hidden defects in 2D dielectrics with light

A material may appear flawless on the surface yet fail to function properly. The cause lies in structural defects hidden within two-dimensional thin films, which are considered key materials for next-generation semiconductor ...

Phys.org / Gold nanoparticles unlock vibrant structural colors across the visible spectrum

Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues ...

Phys.org / AI spots smuggled seahorses, shark fins and sea cucumbers with 92% accuracy

When we think of wildlife trafficking, we might think of rhino horns or baby orangutans sold as pets—but the smuggling of sea creatures, a less well-known crime, is just as damaging to marine ecosystems. Unfortunately, many ...

Tech Xplore / New technology makes it possible to be a seafarer—on land

Uncrewed vessels can navigate themselves and notify operators when they need support from shore-based navigators. However, such ships also require an international regulatory framework. Now, the first version is in place, ...

Medical Xpress / Simple leukemia treatment change in India cuts early child deaths

A landmark Indian clinical trial has found that giving steroids in short bursts instead of continuously can halve early treatment-related deaths in children with leukemia without reducing their chances of being cured. The ...

Phys.org / 'All-in-one' platform developed for multiple trait stacking in crops

A major goal of modern crop breeding is to efficiently combine multiple desirable traits by "stacking" the favorable gene variants (alleles) that contribute to those traits in a single crop variety. However, current strategies ...

Phys.org / First nonrepeating biological clock discovered in C. elegans guides growth

Imagine a train parked at the station. Passengers climb aboard and find their seats. Conductors move up and down the aisles, checking tickets. But there's a problem—the engineer's watch is broken. As a result, the doors never ...
