Phys.org / Ultraluminous X-ray source in Whale galaxy investigated for spectral and timing variability
Astronomers from Germany and Turkey have analyzed available data from various space telescopes to investigate an ultraluminous X-ray source designated X-4, which is located in the nearby galaxy NGC 4631. Results of the new ...
Phys.org / Beetle-like borings in 70-million-year-old titanosaur fossils reshape Lo Hueco fossil story
Traces or perforations caused by living organisms after an animal's death can be found on various dinosaur bone remains. These perforations, known as bioerosion structures, provide information that helps us understand relationships ...
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 / Evidence identifies ancient Aboriginal mining in the Riverland
Flinders University researchers, in partnership with the River Murray and Mallee Aboriginal Corporation, have found evidence that points to 7,000 years of Aboriginal mining of stone at Sugarloaf Hill in South Australia's ...
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 / 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 / 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 / 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 / Ocean warming above 1.5°C triggered year-round marine disruption across globe, study shows
Researchers at King Abdullah University of Science and Technology (KAUST) led one of the first global assessments of how marine ecosystems responded during the first year when global temperatures temporarily exceeded 1.5°C ...
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 ...
