Phys.org / Laser-cut aluminum foil could replace costly terahertz polarizers
When physicists at the ARC Centre for Transformative Meta-Optical Systems (TMOS) needed a key component for their terahertz experiments, they ran into a frustrating problem—they needed tiny optical devices, known as wire-grid ...
Phys.org / Thunderquakes enable seismic imaging of Earth's shallow subsurface
Seismic waves produced by thunderstorms, called thunderquakes, can be used as a novel source for seismic imaging, according to a new study led by researchers at Penn State.
Phys.org / Hydrogel platform uses vitamin B2 and blue light to simplify living tissue models
Researchers at Tampere University have developed a versatile hydrogel platform that makes it easier to create customized biomaterials for tissue engineering, disease modeling, drug discovery and regenerative medicine. Their ...
Phys.org / New ROOT method charts a path to reversing biological changes once thought irreversible
Once a cell has locked into an abnormal state—the way cancer cells do—can it ever be restored to normal? A KAIST research team led by Professor Kwang-Hyun Cho of the Department of Bio and Brain Engineering has, for the first ...
Phys.org / First 15 days of egg development may determine survival for California's most endangered salmon
Sacramento River winter-run Chinook salmon are California's most endangered salmon, with a single surviving population and an average of a few thousand returning fish in recent decades. Shasta Dam blocks their original habitat ...
Phys.org / Shipwrecks from WWI and WWII are polluting the North Sea
In April 1917, the German submarine UC-30 sailed beneath the waves off the coast of Rømø. It had originally been on a mission in Ireland, but after suffering engine trouble, it turned around and was almost home in Germany.
Phys.org / 'Rainbow-on-a-chip' could help unlock 6G networks and precision timing for quantum technologies
Loughborough University physicists and an international team have demonstrated that a grain-of-rice-sized microchip can be used to produce a spectrum of precisely spaced frequencies of light, which is then converted into ...
Phys.org / Lab-grown brain models gain a sense of place
The human brain is often described as one of the most complex structures in biology, and much of its power comes from how it's organized. Its outer layer, the cerebral cortex, is not one uniform sheet. As the brain develops, ...
Phys.org / Climate change could triple the price of wheat
Bread, pasta and breakfast cereals may seem far removed from dry fields in North America, Europe or Asia. Yet when water shortages hit several of the world's most important wheat-growing regions simultaneously, the consequences ...
Phys.org / Scientists map hair follicle formation in spacetime, advancing understanding of how organs develop
In a new research report, scientists at Johns Hopkins Medicine say they have developed a technology that allows them to capture a 3D molecular "snapshot" of hundreds of hair follicles as they develop and then reconstruct ...
Phys.org / Realistic solid-state model brings fractons in quantum spin liquids closer to detection
Quasiparticles arise from the complex interaction of many particles in solids; for example, we describe lattice vibrations in crystals as phonons. Fractons are exotic quasiparticles that occur at the vertices of magnetic ...
Phys.org / Iron hydride enters an exotic state of matter under Earth's inner-core conditions
Earth's inner core, composed primarily of iron with a small percentage of light elements, may enter a superionic state at extreme pressure and temperature, according to experimental results from researchers at Science Tokyo. ...
