Measurements from ‘lost’ sea glider provide new insights into Antarctic ice melting
Gillian Damerel (former UEA) prepares to deploy the Sea Glider Merlin with the Ross Ice Shelf in the background. Credit: Walker Smith A new study reveals for the first time how rising sea temperatures have accelerated the melting of Antarctica’s major ice shelves over the past 40 years. Scientists at the University of East Anglia (UEA) say the study, which…

Study finds that eddies provide upwelling nutrients and improve productivity around the Hawaiian Islands
Credit: Troy Squillaci from Pexels Other than colorful coral reefs and diverse coastal ecosystems, the Pacific waters surrounding the Hawaiian Islands are relatively devoid of marine life and have low biological productivity. A new study published by oceanographers at the University of Hawai’i (UH) Mānoa shows that eddies on the leeward side of the Hawaiian Islands can provide nutrients not…

How volatile organic compounds strengthen plant defenses and provide sustainable pest control solutions
Plants that are attacked or infested by pests emit VOCs that send signals to nearby healthy plants. This strengthens and improves the defense mechanisms of neighboring plants against pests and pathogens. Credit: Genichiro Arimura / TUS, Japan Volatile organic compounds (VOCs) are important airborne signals or odors that allow plants to communicate with other organisms and plants over short and…

The angles where atoms meet could provide a path to new materials under extreme conditions
Credit: Nano Letters (2024). DOI: 10.1021/acs.nanolett.4c02395 How can we design materials that are stronger and lighter? What about new materials for extreme conditions such as jet engines and spacecraft? Associate Professor of Materials Science and Engineering in the PC Rossin College of Engineering and Applied Sciences at Lehigh University The answer, says one Fadi Abdel-Jawad, may lie in the infinitesimal…

How did the building blocks of life reach Earth? Zinc fingerprints in meteorites provide clues
An iron meteorite from the core of a molten planetesimal (left) and a chondrite meteorite from a “primitive” unmolten planetesimal (right). Credit: Rayssa Martins/Ross Findlay Researchers used the chemical fingerprint of zinc in meteorites to determine the origin of volatile elements on Earth. The results suggest that without the “unmolten” asteroids, there may not have been enough of these compounds…
