Researchers have recently found a new way to summon useful structures in magnetic materials using light, heat, and electric fields. This new method, described in a new study published in Physical Review Letters, may lead to more energy-efficient and flexible technologies for data storage and optical devices.
After Memphis Police Officer Torres-Molina searched the man and removed a firearm, he attempted to detain the suspect in a cruiser; the suspect then pulled out a second handgun and shot the officer
You’re an anaerobic microbe sunbathing on a Martian beach billions of years ago listening to the small waves hit the shoreline as you take in the perchlorates in the Martian regolith. This is because while Mars is warm and wet, it still lacks sufficient oxygen, so anaerobic life like yourself doesn’t need oxygen to survive. You’re chilling for several hours and eventually notice the water hasn’t touched you. You remember overhearing some otherworldly fellows who briefly landed and discussed the landscape didn’t look well formed, so they left.
When physicists fire beams of fast electrons at materials, they often need to know exactly how much energy those electrons will lose as they travel through. Through new research published in Physical Review Letters, a team led by Ke Jiang at Shenzhen Technology University in China has found that porous, mostly empty foam materials can stop high-current electron beams far more effectively than denser materials—overturning many previous assumptions about how these beams interact with solid materials.
In the spring of 2025, baseball fans were treated to a surprise when the New York Yankees began the season with a unique style of bat. Termed “torpedo bats,” these new designs tapered slightly toward the end, so the widest points of the bats were closer to the “sweet spot”—the optimal place to hit to send the ball flying. In theory, this shape was more ergonomic, giving the Yankees an advantage at the plate.
In Olympic weightlifting, a single kilogram plate can be the difference between gold and silver. As much as possible, elite athletes must use everything they can to their advantage.
It’s been 37 years since scientists first demonstrated the ability to move single atoms, suggesting the possibility of designing materials atom by atom to customize their properties. Today there are several techniques that allow researchers to move individual atoms in order to give materials exotic quantum properties and improve our understanding of quantum behavior.

When you think of outer space, you’re likely picturing stars, planets and moons. But much of space is filled with clouds of gas, plasma and stardust—known as interstellar clouds.
Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which electrons are localized inside a crystal, while their centers of charge lie in empty spaces between atoms, rather than on the atoms themselves.
Ganymede, Jupiter’s largest moon, is also the solar system’s largest satellite, even larger than the planet Mercury. It is also the only celestial body aside from Earth (and the gas giants) to have an intrinsic magnetic field. As if this didn’t make the icy body interesting enough, scientists also predict that it has a massive interior ocean with more water than all of Earth’s oceans combined. At present, the European Space Agency’s (ESA) Jupiter Icy Moons Explorer (JUICE) is in transit to Ganymede to explore it for signs of habitability.
Gravitational wave researchers working on the world’s most sensitive scientific instruments have found a way to tune their detectors using a process akin to the pitch-correction used in music production.
The largest-ever survey of physicists from around the world—released today—shows a distinct lack of consensus across many of physics’s most important questions, from the nature of black holes and dark matter, to the still-incomplete unification of Einstein’s theory of gravity with quantum mechanics.
If you’ve ever taken an introductory astronomy class, you’ve probably seen the Hertzsprung-Russell (HR) diagram. This graph maps out the life cycle of stars by plotting their temperature against their luminosity, and has been a “cheat sheet” for stellar astrophysics for over a century. But the universe is full of more than just stars, and a new paper in the journal Publications of the Astronomical Society of the Pacific by Gabriel Steward and Matthew Hedman of the University of Idaho, attempts to do for the density and mass of all objects what the HR diagram did for the lifecycle of stars—provide a coherent, visual map to represent them.
Technion researchers have developed, for the first time, a comprehensive physical model explaining how the properties of a radiating material, including absorption, emission, and quantum efficiency, affect the fundamental characteristics of the light it emits as a function of temperature. In essence, the emitted light changes its color, intensity, and randomness according to the material’s properties and its temperature. The discovery was published in Optica and opens new possibilities for designing advanced light sources, optical sensors, and thermally based photonic systems.
