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 / 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 ...
Phys.org / Beyond chemistry: How mechanical forces shape brain wiring
During brain development, neurons extend long processes called axons. Axons link different areas of the brain and carry signals within it and to the rest of the body. Growing axons "wire up" the brain by following precise ...
Phys.org / Water makeup of Jupiter's Galilean moons set at birth, new study finds
While Io, the most volcanically active moon in the solar system, appears completely dry and devoid of water ice, its neighbor Europa is thought to harbor a vast global ocean of liquid water beneath its icy crust. A new international ...
Phys.org / Drones reveal how feral horse units keep boundaries
For social animals, encounters between rival groups can often lead to conflict. While some species avoid this by maintaining fixed territories, others, like the feral horses, live in a "multilevel society" where multiple ...
Phys.org / How shifting tectonic plates drove Earth's climate swings
Carbon released from Earth's spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ice ages and warm climates, new research finds.
Phys.org / To fight cancer, scientists customize cellular protein
Precise methods for shredding or repairing and replacing specific cancer-causing proteins in a malignant cell, developed at the University of Massachusetts Amherst, could have applications beyond cancer to a wide range of ...
Phys.org / Intricacies of Helix Nebula revealed with Webb
NASA's James Webb Space Telescope has zoomed into the Helix Nebula to give an up-close view of the possible eventual fate of our own sun and planetary system. In Webb's high-resolution look, the structure of the gas being ...
Phys.org / Pūkeko birds combine sound elements to create complex call sequences for communication, study reveals
Pūkeko use sound elements to create calls and combine them to create complex call sequences in order to expand the range of options for expressing themselves—these are the findings of an international team including Konstanz ...
Phys.org / ALMA reveals teenage years of new worlds
Astronomers have, for the first time, captured a detailed snapshot of planetary systems in an era long shrouded in mystery. The ALMA survey to Resolve exoKuiper belt Substructures (ARKS), using the Atacama Large Millimeter/submillimeter ...
Phys.org / The last spiny dormouse in Europe
Today, only one species of the spiny dormouse survives, in southern India. However, the oldest spiny dormouse in evolutionary history, a member of the rodent family, was found in sediment dating back 17.5 to 13.3 million ...
Phys.org / A two-week leap in breeding: Antarctic penguins' striking climate adaptation
A decade-long study led by Penguin Watch, at the University of Oxford and Oxford Brookes University, has uncovered a record shift in the breeding season of Antarctic penguins, likely in response to climate change.
