Controlling ice crystal growth using polymer nanoparticles

Ice formation can damage biological samples, tissues and materials during freezing and thawing. In nature, specialized molecules known as ice-binding proteins prevent ice crystals from growing too large, helping organisms survive in extreme cold. Scientists have long tried to rep

Adidas, Uniqlo and Calvin Klein ads in UK banned over ‘recycled’ clothing claims

UK regulator has increased its scrutiny of fashion retailers over potentially misleading environmental statementsAds for Calvin Klein, Adidas and Uniqlo promoting “recycled” clothing and shoes have been banned by the UK watchdog after the advertisers were unable to prove their gr

New superconducting X-ray detector is up to 1,000 times more sensitive

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The advance enables scientists to explore atomically thin materials, nanostructures, and ul

‘No one believed it’: how a YouTube video accidentally proved Libya’s sand cat really does

Wildlife photographer Mohammed Almuntasir had no idea what he had found until scientists started to get in touchWhen wildlife photographer Mohammed Almuntasir uploaded 18 seconds of footage to YouTube, he thought little more about the small, pale cat seen digging a hollow in the

Interlayer self-doping could unlock room-temperature multiferroics in atom-thin materials

Multiferroics are materials that exhibit more than one prominent "ferroic" property, such as ferromagnetism and ferroelectricity. One of their most advantageous features is that they allow engineers to control their magnetic states with electric fields or vice versa, due to an ef

The universe may be hiding conscious minds stranger than we can imagine

What if consciousness isn’t limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on Earth. Drawing on the vastnes

Scientists catch classical space-time crystals moving like Majorana quasiparticles

A research team from Hiroshima University, the University of Colorado, and other collaborators have demonstrated that space-time crystals—exotic structures that, under external drive, loop endlessly through both space and time—can be created using everyday liquid-crystal material

Electron buildup at 2D interface reveals how Janus semiconductors form at room temperature

Researchers at Tohoku University have uncovered the long-standing mystery behind the synthesis of Janus two-dimensional (2D) semiconductors, paving the way for more precise manufacturing of materials used in future electronics and clean energy technologies.

Ultrafast X-rays allow researchers to 'watch' how molecules rearrange during a chemical re

Since the 1980s, researchers have sought to use laser light to control chemical reactions relevant to photochemistry, catalysis and light-responsive materials. But this technique, known as coherent control, has a blind spot: There has been no way to directly see the molecules in

A magnetic field that kills superconductivity can also bring it back

Magnetic fields are generally known to destroy superconductivity in a material. However, in exceptional cases, they can lead to what is known as "re-entrant superconductivity"—where superconductivity disappears as expected, but then unexpectedly returns when the magnetic field is

Quantum waves reveal one-sided motion marking elusive critical states

Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist Philip W. Anderson first described a phenomenon via which irregularities or other sources of disorder in materials would prevent waves from propagating freel
