Phys.org / Unknown 4,000-year-old stone circle in Belfast uncovered by archaeologists
Archaeologists have uncovered an unknown stone circle that dates back at least 4,000 years to the Late Neolithic or Early Bronze Age and was most likely used for ritual activities.
Phys.org / How a 'copper economy' helps fungi and bacteria build stubborn biofilms
Scientists have discovered that two common human pathogens can work together by managing copper in their shared environment—a finding that could open new ways to break down stubborn mixed biofilms.
Phys.org / Sea anemones reveal antiviral defense that reverses human immune playbook
A new study has uncovered a previously unknown antiviral defense mechanism in sea anemones, revealing that animals may have evolved more than one way to fight viral infections. Researchers discovered that a protein resembling ...
Phys.org / Clean crystal surface lets single molecules hit ultimate quantum limit
Scientists at the Max Planck Institute for the Science of Light (MPL) have developed a technique for interrogating molecules on surfaces with spectroscopic precision, thereby reaching the ultimate quantum limit for the first ...
Phys.org / Pegasus launch to deploy LINK for months‑long orbit boost of aging Swift
A mission to raise the orbit of NASA's Neil Gehrels Swift Observatory is poised for launch no earlier than Tuesday, June 30, at 6:23 a.m. EDT (10:23 p.m. UTC+12), from Kwajalein Atoll, part of the Republic of the Marshall ...
Phys.org / Scientists find evidence of vast hidden magma systems inside Mars
Researchers from the University of Oxford have uncovered evidence that Mars once hosted enormous, Earth-like magmatic systems deep beneath its surface—despite the planet lacking the plate tectonics long thought necessary ...
Phys.org / Ancient ocean circulation reversed Atlantic and Pacific oxygen patterns 15 million years ago
The eastern tropical Pacific Ocean is known for its large low-oxygen zones that are increasing in size, putting marine life at risk. New research shows that 15 million years ago, the opposite was true.
Phys.org / Semiconductor quantum dots 'reawaken' predicted Rabi oscillations, boosting quantum control
Physicists at Paderborn University have, for the first time, experimentally demonstrated the so-called "return" of Rabi oscillations in semiconductor quantum dots. The phenomenon, which was first predicted theoretically in ...
Phys.org / Novel crystal strategy delivers near-perfect zero thermal expansion from 11 K to 893 K
Almost every material expands when heated. Well-known examples include railroad tracks and concrete roadways, which feature visible expansion gaps to accommodate this effect. However, thermal expansion poses a far more acute ...
Phys.org / Glass cells of atoms offer a new path to smarter, cheaper sensors
More accurate navigation systems and improved wireless communications may not come from traditional electronics, but rather from atoms. Researchers at Penn State and the National Institute of Standards and Technology (NIST) ...
Phys.org / May 2024 superstorm drew most ring current ions from Earth, not solar wind, research reveals
In May 2024, auroras were observed at unusually low latitudes across the globe, lighting up skies that rarely see such displays. Inside Earth's magnetosphere, the region of space surrounding our planet and dominated by its ...
Phys.org / European heatwave's unlikely accomplice: An ocean 'cold blob'
The heat wave battering Europe may have an unlikely partner in crime: a patch of cold ocean water south of Iceland and Greenland that can influence weather patterns over the continent.
