Stellar explosion in Earth's proximity
When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova—a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned ...

Achieving invisibility: Cross-wavelength invisibility integrated with invisibility tactics
Invisibility is a superior self-protection strategy of long-standing interest in academia and industry, although the concept is thus far most popularly encountered in science fiction. In a new report on Science Advances, ...
Breaking new ground in the search for dark matter
The Large Hadron Collider (LHC) is renowned for the hunt for and discovery of the Higgs boson, but in the 10 years since the machine collided protons at an energy higher than previously achieved at a particle accelerator, ...

First observation of nutation in magnetic materials
Much of the 'memory' of the world and all our digital activities are based on media, hard disks, where the information is encoded thanks to magnetism, by orienting the spin of electrons in one direction or the other.

The magnetization dynamics of rare-earth metals and the role of ultrafast magnon generation
Rare-earth magnetism is dominated by localized 4f electrons, relative to inner transition metals (that are mostly comprised of lanthanides) and cannot be directly excited through an optical laser pulse. As a result, ultrafast ...
Evolution of pine needles helps trees cope with rainfall impact
If you have ever hiked in the woods and been surrounded by the sight and smell of pine trees, you may have taken a closer look at pine needles and wondered how their shape, material properties, and surface wettability are ...

Understanding ghost particle interactions
Scientists often refer to the neutrino as the "ghost particle." Neutrinos were one of the most abundant particles at the origin of the universe and remain so today. Fusion reactions in the sun produce vast armies of them, ...

Research reveals how wounds heal in 'waves'
Many cells in our bodies are on the move and somehow seem to 'know' where to go. But how do they learn the location of their destination? This question is key to understanding phenomena such as the renewal of cells in our ...

Helium, a little atom for big physics
Helium atom precision measurements and calculations have a history of nearly a century. In the 1960s, theorists discovered that the fine-structure split (23P0-23P2) of the 23P energy level of helium is the best atomic system ...

Plasmonic enhancement of stability and brightness in organic light-emitting devices
Scientists investigate free electrons and the resonant interactions of electromagnetic waves in the field of plasmonics. However, the discipline still remains to be extended to large-scale commercial applications due to the ...
Antiferromagnet lattice arrangements influence phase transitions
Antiferromagnets contain orderly lattices of atoms and molecules, whose magnetic moments are always pointed in exactly opposite directions to those of their neighbors. These materials are driven to transition to other, more ...

The realization of active microscale Marangoni surfers
Marangoni surfers are small particles that self-propel while straddling a fluid-fluid interface in a way similar to that in which a surfer moves on the surface of a wave. In recent years, self-propelling particles have become ...
Scientists achieve higher precision weak force measurement between protons, neutrons
Through a one-of-a-kind experiment at the Department of Energy's Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result quantifies the weak ...
