Newly confirmed supernova remnant is one of the faintest ever detected

An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The newfound supernova remnant, dubbed Abeona, is one of the faintest radio SNRs so far detected. The discovery is detailed in a research paper published April 21 on the arXiv preprint server.

Team develops modulator for compact photonic integrated circuits

Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics that enables high-efficiency optical signal control within a small device footprint. The development could find applications in optical communication systems, analog-to-digital conversion, as well as in devices for generating and processing ultra-high-frequency signals based on photonic technologies.

Thinner than hair and stretchable like rubber, this new shield tackles a space-age problem in one layer

Shielding materials are essential in key modern industrial settings—such as spacecraft, nuclear power plants, semiconductor equipment, and advanced medical devices—to protect both equipment and personnel from electromagnetic waves and radiation. In particular, as space exploration gains momentum—such as with the successful launch of Artemis 2 on the 2nd—the importance of next-generation shielding technology capable of […]

Light can now be shaped in empty space, and it could simplify sensing and boost data links

Scientists at the University of East Anglia have uncovered a hidden property of light that allows it to twist, spin and behave differently—without mirrors, materials or special lenses. In a breakthrough that could transform medical testing, data transmission and future quantum technologies, researchers from the UK and South Africa have shown that light can be […]

Hidden stripe pattern lets microscopes auto-focus across 400 times deeper range

Anyone who has ever used a microscope knows that it takes time to bring a sample into sharp focus. Each time you move the slide, the image blurs, and you have to stop and carefully turn a knob to bring everything back into clear view. For scientists and clinicians, even if the motion is semi-automated, […]

Investigating the disordered heart of glass

Recent research led by the University of Trento reveals that fundamental atomic vibrations remain unchanged also in ultra-stable glasses. This discovery advances the decade-long debate on the physics of disorder and opens the way to new applications, from electronics to pharmaceuticals. The research work was carried out by the Department of Physics in collaboration with […]

NASA fires up powerful lithium-fed thruster for trips to Mars

A technology that could propel crewed missions to Mars and robotic spacecraft throughout the solar system was recently put to the test at NASA’s Jet Propulsion Laboratory in Southern California. On Feb. 24, for the first time in years and at power levels exceeding any previous test in the United States, a team fired up […]

A mechanical blue LED: Stretching GaN shifts light from UV to blue without changing chemistry

A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical stretching technology to dynamically control the emission color of gallium nitride (GaN) material from ultraviolet (UV) to blue light. This technological breakthrough provides a new semiconductor material control solution for future advanced power transistors, optoelectronic components, […]

Image: Fiery fall color in southern Chile

The bright whites of mountain snow, muted browns of the arid plains, and gem-like blues and teals of glacial lakes typically dominate the Patagonian color palette. But for a short time in the austral autumn, temperate deciduous forests add splashes of warm tones. On April 12, 2026, a break in the clouds allowed the Landsat […]
