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 ...

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.

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 ...

Quieter wind beneath the wings

Efficiently simulating the noise generated by wings and propellers promises to accelerate the development of quieter aircraft and turbines.

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 use of graph neural networks to discover particles

Machine learning algorithms can beat the world's hardest video games in minutes and solve complex equations faster than the collective efforts of generations of physicists. But the conventional algorithms still struggle to ...

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 ...
