Published Evidence from the remains of 1918 flu pandemic victims contradicts long-held belief that healthy young adults were particularly vulnerable
(via sciencedaily.com) Original source New analysis of the remains of victims of the 1918 influenza pandemic, which killed an estimated 50 million people worldwide, contradicts the widespread belief the flu disproportionately impacted healthy young adults.
Published Discovery of invisible nutrient discharge on Great Barrier Reef raises concerns
(via sciencedaily.com) Original source Scientists using natural tracers off Queensland’s coast have discovered the source of previously unquantified nitrogen and phosphorus having a profound environmental impact on the Great Barrier Reef. Groundwater discharge accounted for approximately one-third of new nitrogen and two-thirds of phosphorus inputs, indicating that nearly twice the amount of nitrogen enters the Reef from groundwater compared to river waters.
Published Researchers identify largest ever solar storm in ancient 14,300-year-old tree rings
(via sciencedaily.com) Original source An international team of scientists have discovered a huge spike in radiocarbon levels 14,300 years ago by analyzing ancient tree-rings found in the French Alps. The radiocarbon spike was caused by a massive solar storm, the biggest ever identified. A similar solar storm today would be catastrophic for modern technological society – potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions. The academics are warning of the importance of understanding such storms to protect our global communications and energy infrastructure for the future.
Published Tropical ecosystems more reliant on emerging aquatic insects, study finds, potentially putting them at greater risk
(via sciencedaily.com) Original source Researchers have found that tropical forest ecosystems are more reliant on aquatic insects than temperate forest ecosystems, making them more vulnerable to disruptions to the links between land and water. This is a significant finding, as tropical forests play a vital role in global biodiversity and climate regulation. The study's authors warn that any disruption to the land-water connections in these ecosystems could have serious consequences for their health and resilience.
Published Plate tectonic surprise: Geologist unexpectedly finds remnants of a lost mega-plate
(via sciencedaily.com) Original source Geologists have reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean. The team had predicted its existence over 10 years ago based on fragments of old tectonic plates found deep in the Earth’s mantle. To the lead researchers surprise, she found that oceanic remnants on northern Borneo must have belonged to the long-suspected plate, which scientists have named Pontus. She has now reconstructed the entire plate in its full glory.
Published Newly-discovered 'margarita snails' from the Florida Keys are bright lemon-yellow
(via sciencedaily.com) Original source A newly-discovered, bright yellow snail has been discovered in the Florida Keys and named in honor of Jimmy Buffet's song 'Margaritaville.' The lemon-colored marine snail, along with its lime-green cousin from Belize, is the subject of a recent study ; researchers think these snails' bright colors might help deter predators.
Published The Gulf Stream is warming and shifting closer to shore
(via sciencedaily.com) Original source The Gulf Stream is intrinsic to the global climate system, bringing warm waters from the Caribbean up the East Coast of the United States. As it flows along the coast and then across the Atlantic Ocean, this powerful ocean current influences weather patterns and storms, and it carries heat from the tropics to higher latitudes as part of the Atlantic Meridional Overturning Circulation. A new study now documents that over the past 20 years, the Gulf Stream has warmed faster than the global ocean as a whole and has shifted towards the coast. The study relies on over 25,000 temperature and salinity profiles collected between 2001 and 2023.
Published Newfound mechanism suggests drug combination could starve pancreatic cancer
(via sciencedaily.com) Original source A study found that a new combination of treatments safely decreased growth of pancreatic cancer in mice by preventing cancer cells from scavenging for fuel.
Published Epigenetic regulator MOF drives mitochondrial metabolism
(via sciencedaily.com) Original source Researchers have unveiled a new mechanism for regulating mitochondrial function. The findings reveal the critical role played by the enzymatic activity of the lysine acetyltransferase MOF in maintaining mitochondrial integrity and function through acetylation of mitochondrial electron transport chain component COX17. Cells lacking MOF-mediated COX17 acetylation exhibit dramatic mitochondrial defects and impaired ability to produce energy. Underscoring the clinical relevance of these findings, the team also showed that cells from human patients with a developmental disorder caused by mutations in MOF also exhibited respiratory defects that could be ameliorated by interventions such as acetylation-mimetic COX17 or mitochondrially targeted MOF.
