New findings about ocean processes in the Antarctic show melting ice shelves and changes to sea ice could have catastrophic implications for the global climate.
18 December 2025 / Kiel / Plymouth. The ocean may have absorbed significantly more carbon dioxide (CO2) than previously calculated. A new study by the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Plymouth Marine Laboratory shows that the exchange of gases between air and sea is not symmetric, and that the global ocean has taken up around 15 per cent more CO2 than suggested by conventional estimates. In windy regions, air bubbles entrained by breaking waves substantially enhance the uptake of CO2. The results are based on extensive direct measurements from the ocean and have now been published in the journal Nature Communications.
Researchers from CIC nanoGUNE, in collaboration with the Donostia International Physics Center (DIPC) and the Center for Materials Physics (CFM), have experimentally observed and theoretically verified flat-band ultrastrong coupling between optical phonons and surface plasmon polaritons. Published in Nature Materials, the study reveals a previously unexplored regime of light–matter interaction with potential applications in polariton-driven chemistry, materials science, nanophotonics, and quantum engineering.
Experimental drug NU-9 shows promise in clearing toxic proteins associated with neurodegenerative diseases. Scientists tested NU-9 in a pre-symptomatic animal model of Alzheimer’s disease. Drug dramatically reduced brain changes that emerge near the disease’s onset. Researchers have hope that NU-9 could act as a potential prophylaxis to prevent Alzheimer's symptoms from appearing.
Proteolysis-targeting chimeras (PROTACs) are molecules that can eliminate disease-causing proteins, but developing them is often slow and complex, limiting how quickly new candidates can be tested. Now, researchers from Tokyo University of Science have developed a three-step "click chemistry" assembly line that rapidly builds functional PROTACs from simple building blocks. The resulting molecules successfully degraded a target protein in cells, paving the way for faster, more flexible development of protein-targeting therapeutics.
Power factor correction (PFC) circuits are ubiquitous in consumer electronics. In a new study, researchers from Chonnam National University present a simple, sensorless control method for boost PFC that eliminates the need for current sensors, thereby reducing cost, noise, and complexity while maintaining high performance. By deriving a new duty cycle equation that only requires voltage measurements and introducing delay compensation, the method demonstrates strong performance in a 1.3 kW prototype across various loads.
