Phys.org / Archaeologists uncover 11 rare marked arrowheads at Tepecik-Çiftlik whose purpose remains a mystery
For decades, archaeologists have been uncovering rare and mysterious incised obsidian arrowheads across Neolithic Central Anatolia, each one bearing a unique design etched into its glassy black surface nearly 9,000 years ...
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 / '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 / 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 / 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 / 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 / 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 / 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 / Seeing the unseen: A new tool visualizes hidden structures in complex biological data
Modern biology research can now generate valuable data on an unprecedented scale. But there is one major obstacle: making sense of these complex high-dimensional datasets. A team at the University of Basel, Switzerland, has ...
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 / 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 / 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 ...
