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 / Universal pattern revealed in quantum matter
When different materials transition from one phase to another, such as water coming to a boil or a magnet losing its ability to attract metals, something remarkable can happen: They begin to behave identically, following ...
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 / RNA droplets may have helped start life on Earth
It's one of the origins-of-life chicken-or-egg problems: How could RNA have helped give rise to the first cells before there were cells to contain it?
Medical Xpress / Why memories get fuzzier with age—and what replaces them
Research from the University of East Anglia shows how our memories change with age and why specific details associated with past events can fade over time. The new study reveals that as people age, they not only remember ...
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 / 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 / New Monte Carlo method accelerates simulations of densely entangled polymer melts
Long polymer chains are everywhere: in synthetic materials, soft matter, biological systems such as chromosomes, and mathematical models of filaments and knots. When many such chains are densely packed, they form what physicists ...
Phys.org / Stellar eruptions in the laboratory: First experimental evidence for their suppression in strong magnetic fields
An international team of astrophysicists and plasma physicists has provided the first experimental evidence that strong magnetic fields surrounding active stars can completely suppress coronal mass ejections. This offers ...
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. ...
