Acceptor molecule upconverts low-energy green light to high-energy purple with high effici

Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply pass through the material without being used as energy

Scientists create quantum sound device that could transform communications

A new quantum device can generate precisely controlled bursts of sound-like particles, or phonons, by forcing electrons through an ultra-thin crystal at extremely low temperatures. The surprising behavior pushes beyond the limits predicted by current theories, suggesting scientis

Scientists reveal what really happens when water is trapped in tiny spaces

A decades-old puzzle about water has finally been unraveled. Researchers found that water trapped in tiny nanoscale spaces is not inherently more reactive. Instead, the intense pressures created inside these microscopic gaps explain most of the effect, while the surrounding mater

Tiny magnetic waves could unlock quantum computers the size of a penny

A major breakthrough in quantum technology has turned magnons, tiny magnetic waves once considered too short-lived for practical use, into promising carriers of quantum information. Researchers extended their lifetime by nearly 100 times, reaching up to 18 microseconds, and disco

‘A sanitized view of America’: inside Trump’s campaign to erase US history from national p

Critics say the Trump administration is trying to rewrite and whitewash history by removing and altering scores of signs on public landsJerry Bransford, a former US National Park Service (NPS) ranger, has always had a deep connection with the land he grew up on – and the land hun

Hidden role of garnet reveals how Earth's 660-km seismic boundary forms

Nearly 660 kilometers (410 miles) beneath Earth's surface lies one of the planet's most important internal boundaries. Known as the 660-km seismic discontinuity, it separates the mantle transition zone from the lower mantle and plays a central role in controlling how heat and mat

MOF thin films reveal hidden dense packing, challenging decades of porous assumptions

Due to their high porosity, metal-organic frameworks (MOFs) are regarded as promising materials for innovative applications, which is why the Nobel Prize in Chemistry was awarded in 2025 for their discovery. They are used, for example, to store gases, to capture CO2 and for the t

Diffractive networks enable optical information transfer through random and unknown diffus

The transmission of optical information through random scattering media is a major challenge in optics, biomedical imaging, telecommunications and remote sensing. When light passes through a turbid or diffusive medium, such as biological tissue or a randomly structured optical ma

Songs play a greater role than plumage color in limiting bird hybridization, study suggest

When trying to attract and recognize potential mates, animals are known to rely on various signals, traits and behaviors. In the case of birds, these signals can typically include a wide range of sounds—such as trills, whistles, chirps or melodious notes defined as "songs"—as wel
