German scientists have discovered that collagen and calcium work together to give grove snails the ability to tune their mucus for five distinct functions, according to a study in Science.
Raji Doshi, a 12-year-old student from Connecticut, is a finalist in the 3M Young Scientist Challenge for her project proposing the use of algae and natural calcium buffers to reduce CO₂-driven ocean acidification. Her innovative idea aims to create healthier marine ecosystems and competes for a $25,000 grand prize.
Northwestern University researchers found strong evidence that ocean acidification, caused by massive volcanic eruptions from the Kerguelen Plateau, triggered a major extinction event for planktic foraminifera around 113 million years ago. Chemical signals in microscopic shells revealed severe stress on shell-building organisms, offering insights into modern ocean changes.
Crop nutrient content has declined for decades, prompting research into solutions. Regenerative agriculture, focusing on soil health, shows promise in boosting nutrient density in some studies, but faces skepticism regarding scalability and cost-effectiveness.
Scientists at NTU in Singapore developed a process converting discarded shrimp shells into carbon-negative hydrogen fuel, aquaculture protein, and calcium carbonate. This lab-scale technology aims to reduce waste and offer cleaner alternatives to fossil-based energy and industrial materials, though commercial scaling faces efficiency and economic hurdles.
Scientists in Singapore have developed a process to convert shrimp shells and other organic waste into hydrogen fuel, protein for aquaculture feed, and calcium carbonate for construction. The technology, developed at Nanyang Technological University, aims to be carbon-negative by removing more CO2 than it produces, offering a dual solution for waste reduction and cleaner energy.
Gaza's improvised cement industry is turning rubble into construction material due to Israeli bans on imports. Workers face severe health risks in makeshift tents, producing a substitute cement that is expensive and not structurally sound, but the only option for many.
The article highlights the wide range of physiological changes during pregnancy and argues for a broader nutritional strategy in India, emphasizing iron, folic acid, and other micronutrients essential for maternal and fetal health.
