Lizard tail preserved in amber sheds light on a 100-million-year-old defense mechanism

A lizard making a dramatic escape, leaving its tail wriggling behind as it darts to safety, is an image familiar to many. Tail-shedding is one of the most widespread defenses against predators among living lizards, yet tracing ...

Tiny shifts in iron content tip a potential memory material between competing magnetic states

A team of Yale researchers has figured out what gives a magnetic material its mysterious properties, a discovery that could help boost computing memory and the field of "spintronics." Their work is published in Physical Review ...

An 'electron waiting room' helps blue titanium dioxide hold light energy longer

To produce hydrogen using sunlight, the energy obtained from light must be retained until it can be used in a chemical reaction. However, if an electron that has gained energy from light quickly returns to its original position, ...

Patterns of polar vortices discovered in lead-free superlattices on silicon

A team at HZB has, for the first time, reported polar vortices in (BaTiO₃/SrTiO₃)₁₀ superlattices on silicon. These results expand the range of materials and substrates on which polar topological textures can occur and open ...

Single X-ray pulse reveals plasma nanostructures across scales with one camera

Understanding instabilities and turbulence in plasmas is one of the key challenges across a wide range of plasma research fields, including nuclear fusion, astrophysics and laser-plasma physics. In plasmas, slight disturbances ...

How flare ribbons reveal hidden solar explosions on the sun

Many topics in astronomy and astrophysics are esoteric. There's not much of a relationship between something like the supermassive black hole at the center of the Milky Way and the life of a regular person going about their ...

New long‑clawed British dinosaur is the first of its kind in Europe

The fossilized skull of a new species of mysterious meat-eating dinosaur from the Isle of Wight has been rediscovered in the collections of the Natural History Museum after over 100 years in storage.

Plain silicon grating reveals a hidden 'twist' in light from electron beams

In 1953, two physicists showed that an electron beam skimming past a grating emits light whose color depends only on the electron's speed and the grating's spacing. Known as Smith-Purcell radiation, this phenomenon has become ...

Elusive uranium 'sandwich' molecule isolated after more than 50 years

In a study published in Nature Communications, researchers from The University of Manchester and Lancaster University have isolated and characterized uranocenium, the positively charged form of a landmark uranium compound ...

A mineral from the inside of planets reveals a surprising lesson: How you push matters

In the deepest region of the Earth's mantle, just above the core, much of the material consists of crystals of magnesium oxide. In larger rocky exoplanets called super-Earths, the higher pressures in the lower mantle may ...
