Phys.org / AI-driven ultrafast spectrometer-on-a-chip advances real-time sensing
For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory instruments called spectrometers. ...
Phys.org / Scientists discover a hidden RNA 'aging clock' in human sperm
Increasing paternal age has been linked to elevated health risks for the next generation, including higher risks of obesity and stillbirth. But what drives this increased risk remains unknown.
Phys.org / How light suppresses virulence in an antibiotic-resistant pathogen
Light is a universal stimulus that influences all living things. Cycles of light and dark help set the biological clocks for organisms ranging from single-celled bacteria to human beings. Some bacteria use photosynthesis ...
Phys.org / Scientists plan deep-sea expedition to probe 'dark oxygen'
A team of scientists announced Tuesday they have developed new deep-sea landers specifically to test their contentious discovery that metallic rocks at the bottom of the ocean are producing "dark oxygen".
Phys.org / South Pole Telescope detects energetic stellar flares near center of galaxy
Researchers from the South Pole Telescope project team looked deep into the center of the Milky Way, discovering powerful, surprising bursts of light from two accreting white dwarf systems.
Phys.org / Bubble netting knowledge spread by immigrant humpback whales, study finds
New research from the University of St Andrews has found that the social spread of group bubble-net feeding among humpback whales is crucial to the success of the population's ongoing recovery.
Phys.org / Anglo-Saxon center unearthed near Skipsea castle
Archaeologists working near Skipsea Castle in East Yorkshire say a series of rare discoveries is transforming understanding of life in the centuries before the Norman Conquest.
Phys.org / Bats use 'acoustic flow velocity' to navigate complex environments in darkness
A long-standing mystery about how wild bats navigate complex environments in complete darkness with remarkable precision, has been solved in a new University of Bristol-led study. The findings are published in Proceedings ...
Phys.org / North Atlantic deep waters show slower renewal as ocean ventilation weakens
The ocean is continuously ventilated when surface waters sink and transport, for example, oxygen and carbon to greater depths. The efficiency of this process can be estimated using the so-called water age, which describes ...
Phys.org / New quantum boundary discovered: Spin size determines how the Kondo effect behaves
Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, they produce unique effects not seen in individual particles. Understanding how quantum spins interact ...
Phys.org / Direct visualization captures hidden spatial order of electrons in a quantum material
The mystery of quantum phenomena inside materials—such as superconductivity, where electric current flows without energy loss—lies in when electrons move together and when they break apart. KAIST researchers have succeeded ...
Phys.org / Failed battery chemistry offers new way to destroy PFAS
Researchers in the lab of Asst. Prof. Chibueze Amanchukwu at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) have spent three years looking for failure, scouring the academic literature for ...
