Phys.org / Marine regression emerges as key driver of Late Paleozoic Ice Age in high-resolution model
Earth system box models are essential tools for reconstructing long-term climatic and environmental evolution and uncovering Earth system mechanisms. To overcome the spatiotemporal resolution limitations of current deep-time ...
Phys.org / Young galaxies grow up fast: Research reveals unexpected chemical maturity
Astronomers have captured the most detailed look yet at faraway galaxies at the peak of their youth, an active time when the adolescent galaxies were fervently producing new stars.
Phys.org / Superheated sediments in a submarine pressure cooker—an unexpected source of deep-sea hydrogen
The mid-ocean ridge runs through the oceans like a suture. Where Earth's plates move apart, new oceanic crust is continuously formed. This is often accompanied by magmatism and hydrothermal activity. Seawater seeps into the ...
Phys.org / Study overturns long-held model of how plants coordinate immune responses
Plants mobilize their immune defenses far earlier than scientists have believed for decades—and through a previously overlooked early signaling mechanism—according to a new study published in Nature Plants.
Phys.org / Single-atom photocatalyst enables green, oxidant-free C–H cross-coupling reactions
Chemists from the National University of Singapore (NUS) have developed a single-atom photocatalytic strategy that enables oxidant-free cross-dehydrogenative coupling (CDC) reactions between ring-shaped aromatic molecules ...
Phys.org / 'Stomata in-Sight' system allows scientists to watch plants 'breathe' in real-time
For centuries, scientists have known that plants "breathe" through microscopic pores on their leaves called stomata. These tiny valves are the gatekeepers that balance the intake of carbon dioxide into the leaf for photosynthesis ...
Phys.org / From pint to plate, scientists brew up a new way to grow meat
Yeast left over from brewing beer can be transformed into edible "scaffolds" for cultivated meat—sometimes known as lab-grown meat—which could offer a more sustainable, cost-effective alternative to current methods, according ...
Phys.org / How well-meaning allies increase stress for marginalized people
Someone in the office makes a racially insensitive comment, and a white co-worker asks a Black colleague to help correct the offender.
Phys.org / Climate change accelerates tree deaths across Australian forests, study finds
Australia's forests are losing trees more rapidly as the climate warms, a new study examining decades of data said Tuesday, warning the trend was likely a "widespread phenomenon."
Phys.org / House sparrows can help us save endangered species: A mathematical framework for genomic prediction
Researchers are trying to understand why some wild species do better than others over time, as the environment changes.
Phys.org / Researchers sustainably produce triacetic acid lactone from sugarcane
Triacetic acid lactone (TAL) has the potential to serve as a bioderived platform chemical for commercial products, including sorbic acid. However, TAL currently lacks a global market as its chemical synthesis is prohibitively ...
Dialog / Making sense of quantum gravity in five dimensions
Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and particles behave, while general ...
