Phys.org / 2D quantum memory device reaches single-electron limit of information storage
Most electronic memory storage devices require the ability to trap large numbers of electrons for each bit of memory. In an ideal world, however, it would take only one electron. This would reduce space requirements and power ...
Phys.org / From single projection to many possibilities: A new tool for climate risk assessment
Assessing how climate change will affect different regions usually requires running a complex chain of models. While this approach provides valuable insights, it is expensive and can cover only a limited set of scenarios ...
Tech Xplore / Claude AI finds cryptography weaknesses human experts missed
AI company Anthropic has announced that its unreleased model, Claude Mythos Preview, has discovered previously unknown mathematical weaknesses in cryptographic algorithms that human researchers had missed for years.
Phys.org / First 3D map reveals hidden thermal structure of nearby interstellar medium
Astronomers have built the first three-dimensional map of gas temperature in the space surrounding our solar system, revealing a far messier and more dynamic picture than current models predict. The study was submitted to ...
Phys.org / Bringing complex field physics to the tabletop: A photonic stage for non-Abelian gauge fields
For most theories in physics, the order of operations has little impact on the result. When setting a dial to a certain position, for example, it doesn't matter whether it's turned clockwise or counterclockwise—the result ...
Phys.org / Non-monogamy may reduce jealousy overall, but feeling less desirable can still strain relationships
Comparing yourself with your partner is more common than you'd think. Psychologists even have a term for it: mate value discrepancy (MVD), which is the gap between how attractive, smart or successful each partner feels compared ...
Phys.org / Hydrothermal microbes shape seafloor minerals at newly found vents near Greek island
In August 2023, the German research vessel METEOR set sail on Expedition M192 to the Greek island of Milos with Dr. Solveig Bühring as chief scientist. The mission was to locate and investigate previously unknown hydrothermal ...
Phys.org / Most complete skeleton of 30 million-year-old dog discovered
For decades, a 30 million-year-old fossil sat entombed in rock in an Oregon museum collection. When it was first found, paleontologists thought it might be an early relative of sheep, camels and pigs, whose fossilized skeletons ...
Phys.org / Ice Age artists carved thumbnail-size bird figurines from mammoth ivory 40,000 years ago
Excavations at Hohle Fels Cave in the UNESCO World Heritage area of the Swabian Jura in southwestern Germany have again yielded two spectacular 40,000-year-old depictions of birds carved from mammoth ivory. The two figurines ...
Phys.org / Strain turns non-chiral crystals left- or right-handed on demand
Mechanical strain is one of the most common tools used to tailor the properties of materials. In piezoelectric materials, stretching or compressing a crystal generates an electrical polarization. In piezomagnetic materials, ...
Medical Xpress / Less sugar early in life may reduce the risk of Alzheimer's
Sugar restriction during the first 1,000 days after conception may significantly reduce a person's risk of developing Alzheimer's by up to 46%. Those are the findings of a new study published in the journal npj Aging that ...
Phys.org / Lake ice loss could accelerate after winter temperatures cross critical thresholds
For lakes across the Northern Hemisphere, winter ice is more than a frozen surface. It is a seasonal regulator that shapes underwater ecosystems and energy balance. But as the planet warms, this frozen season is disappearing ...
