Twisted crystals open door to smaller, more powerful sensors for optical devices

Twisted moiré photonic crystals—an advanced type of optical metamaterial—have shown enormous potential in the race to engineer smaller, more capable and more powerful optical systems. How do they work?

Imagine you have two pieces of fabric with regular patterns, like stripes or checkers. When you lay the two pieces of fabric directly on top of each other, you can see each pattern clearly. But if you slightly shift one piece of fabric or twist it, new patterns that weren’t in either of the original fabrics emerge.

In twisted moiré photonic crystals, how the layers twist and overlap can change how the material interacts with light. By changing the twist angle and the spacing between layers, these materials can be fine-tuned to control and manipulate different aspects of light simultaneously—meaning the multiple optical components typically needed to simultaneously measure light’s phase, polarization, and wavelength could be replaced with one device.

Error correction method reduces photon requirements for quantum computing

An invention from Twente improves the quality of light particles (photons) to such an extent that building quantum computers based on light becomes cheaper and more practical. The researchers published their research in the journal Physical Review Applied.

Quantum computers are at a tipping point: tech giants and governments are investing billions, but there are two fundamental obstacles: the quantity of qubits and the quality of these qubits. UT researchers have invented a component for a photonic quantum computer that exchanges quantity for quality, and have shown that this exchange yields more computing power.

“Our discovery brings a future with a lot closer. That means improved medicines, new materials and safer communications. But also applications that we cannot yet imagine today,” says lead researcher Jelmer Renema. “This technology is an essential part of any future photonic quantum computer.”

Riding the AI wave toward rapid, precise ocean simulations

AI has created a sea change in society; now, it is setting its sights on the sea itself. Researchers at Osaka Metropolitan University have developed a machine learning-powered fluid simulation model that significantly reduces computation time without compromising accuracy.

Their fast and precise technique opens up potential applications in offshore power generation, ship design and real-time ocean monitoring. The study was published in Applied Ocean Research.

Accurately predicting fluid behavior is crucial for industries relying on wave and tidal energy, as well as for the design of maritime structures and vessels.

Proxima Centauri’s Violent Flares May Endanger Life on Nearby Planets

Located just over four light-years away, Proxima Centauri is our closest stellar neighbor and a highly active M dwarf star. While its frequent flaring has long been observed in visible light, a recent study using the Atacama Large Millimeter/submillimeter Array (ALMA) reveals that Proxima Centauri also exhibits intense activity at radio and millimeter wavelengths. These observations provide new insights into the particle-driven nature of its flares and raise important questions about the star’s impact on the habitability of its surrounding planets.

Proxima Centauri is known to host at least one potentially habitable, Earth-sized planet within its habitable zone. Like solar flares on our Sun, Proxima’s flares emit energy across the electromagnetic spectrum and release bursts of high-energy particles known as stellar energetic particles.

The intensity and frequency of these flares could pose a serious threat to nearby planets. If powerful enough, they can erode planetary atmospheres, stripping away critical components like ozone and water, and potentially rendering these worlds uninhabitable.

X-Rays Reveal Quantum Oddities in Layered Magnets

Our understanding of layered quantum materials is still in its early stages. This is highlighted by new research from the Paul Scherrer Institute (PSI). Using advanced X-ray spectroscopy techniques at the Swiss Light Source (SLS

NASA’s Space Launch System (SLS) will be the most powerful rocket they’ve ever built. As part of NASA’s deep space exploration plans, it will launch astronauts on missions to an asteroid and eventually to Mars. As the SLS evolves, the launch vehicle will to be upgraded with more powerful versions. Eventually, the SLS will have the lift capability of 130 metric tons, opening new possibilities for missions to places like Saturn and Jupiter.

Moon Dust to Power: The Solar Tech That Could Fuel Space’s Next Giant Leap

Scientists have created solar cells using simulated Moon dust, potentially solving one of space exploration’s biggest challenges: how to generate reliable energy far from Earth.

These new cells, made with perovskite and moonglass, are lighter, cheaper, and more radiation-resistant than traditional space solar panels. Even better, they can be made using lunar materials, drastically reducing launch costs and making future Moon bases more feasible. If successful in real lunar conditions, these Moon-made solar panels could power entire off-world colonies.
