Non-genetic reprogramming method to restore sweat gland function shows promise for burn victims
Sweat glands are vital for regulating body temperature, maintaining fluid balance, and supporting skin health. Yet, extensive skin injuries, such as burns, often result in the loss of these glands, leaving patients vulnerable to overheating, dehydrat.....»»
Satellite data and algorithms reveal which ships emit excessive nitrogen
Ships are still emitting too much nitrogen oxide. Until now, it has been impossible to measure this at sea, but that is set to change. Solomiia Kurchaba combined satellite data and developed algorithms to identify which ships are emitting too much. K.....»»

Southeast Asia coastline research highlights the pressures human activities place on tropical marine ecosystems
The tropical coastlines of Southeast Asia are home to some of the most important and biodiverse marine ecosystems on the planet. However, they are also among its most vulnerable, with areas of coral reefs, mangrove forests and seagrass beds under inc.....»»
Plant biologists show how two genes work together to trigger embryo formation in rice
Rice is a staple food crop for more than half the world's population, but most farmers don't grow high-yielding varieties because the seeds are too expensive. Researchers from the University of California's Davis and Berkeley campuses have identified.....»»
Light-activated, drug-carrying liposomes show potential for minimally invasive glaucoma treatments
More than 4 million people in the U.S. have glaucoma, a group of eye diseases that can damage the optic nerve and lead to vision loss. It's the second-leading cause of blindness worldwide and there's currently no cure, but there's a way to help preve.....»»
Heart cockles have windows in their shells to let in light for symbiotic algae
A team of marine biologists, ecologists and evolutionary specialists from the University of Chicago, Stanford University and Duke University has found that heart cockles have windows in their shells to allow in light needed by the algae that live ins.....»»
Researchers develop pioneering monitoring technique to help build mangrove resilience
Mangroves are remarkable ecosystems home to amazing biodiversity, dense vegetation, and conditions that capture large quantities of carbon. Since they occur in warm, tropical, and subtropical coastal regions, they also take the brunt of the impact fr.....»»
Invasive zebra mussels are associated with elevated mercury levels in fish, study finds
A study found that invasive zebra mussels significantly alter aquatic ecosystems, and are associated with elevated mercury concentrations in fish. Mercury, a potent neurotoxin, poses a serious threat to both aquatic life and human health......»»
Astronauts found to process some tasks slower in space, but no signs of permanent cognitive decline
A stay in space exerts extreme pressures on the human body. Astronauts' bodies and brains are impacted by radiation, altered gravity, challenging working conditions, and sleep loss—all of which could compromise cognitive functioning. At the same ti.....»»

The climate and biodiversity crises are entwined, but we risk pitting one against the other
Climate change and biodiversity policies have largely evolved in isolation, even though the two crises are deeply intertwined. They have their own UN summits, with the same name and numbering system: the UN biodiversity summit Cop16 just concluded in.....»»
How marine worms regenerate lost body parts: Return of cells to stem cell-like state could be key
Many living organisms are able to regenerate damaged or lost tissue, but why some are particularly good at this and others are not is not fully understood. Molecular biologists Alexander Stockinger, Leonie Adelmann and Florian Raible from the Max Per.....»»
