Algal blooms explained: How scientists are helping spot them sooner
Algal blooms explained: How scientists are helping spot them sooner Lisa Lock Scientific Editor Andrew Zinin Lead Editor Algal blooms can seem to appear overnight. A stretch of ocean that looked clear days earlier can suddenly appear discolored and sometimes pose risks to ecosystems and human health. But scientists say blooms are rarely sudden—understanding what happens before they appear is key to managing them.
Amplified Arctic iceberg traffic reshapes benthic biodiversity
Abstract The Arctic is undergoing rapid warming, resulting in retreating sea ice and glaciers1, yet how cryospheric changes propagate into the deep ocean remains poorly understood2. Here we identify a climate-driven mechanism linking accelerating glacier disintegration to an increase in deep-sea hard-bottom habitats far beyond calving fronts. Seafloor observations in Fram Strait show a localized increase in the density and patchiness of dropstones delivered by debris-laden icebergs.
How waves, ponds and green algae are accelerating sea ice melt in Antarctica
How waves, ponds and green algae are accelerating sea ice melt in Antarctica Lisa Lock Scientific Editor Andrew Zinin Lead Editor Picture sea ice in your mind. You probably imagine brilliant white, snow-covered floes floating on the surface of the ocean, home to penguins in the south of the globe or polar bears in the north. But our new research shows Antarctic sea ice can turn into rafts of rotting floes (the free-floating pieces of ice) or an icy green slush when it interacts with waves in...
Are Russian spies stealing Western technology? What European intelligence officials claim
Russian intelligence agencies are aggressively intensifying efforts to steal Western technology, defence research and industrial secrets across Europe as sanctions linked to the Ukraine war squeeze Moscow’s wartime economy, senior European intelligence officials told Associated Press. Officials from Sweden, Finland, Estonia and the United Kingdom said Russia is using fake companies, middlemen, cyber spies and covert procurement networks to obtain restricted machinery, software and dual-use...
Russian spies are going after Western technology – they care less about being caught
Russian spies are going after Western technology – they care less about being caught Russia needs sanctioned computer technology and software updates for machine tools - Bookmark Russian intelligence agencies have grown more aggressive in their efforts to steal Western technology and defence secrets, as sanctions squeeze the country's wartime economy, three senior European intelligence officials have told The Associated Press. Moscow's agents are reportedly establishing shell companies,...
How did a major mangrove restoration project in Senegal end up selling 'ghost carbon?'
How did a major mangrove restoration project in Senegal end up selling 'ghost carbon?' Lisa Lock Scientific Editor Andrew Zinin Lead Editor Nature-based solutions have become central to global climate strategies. From tropical forests to wetlands, restoring nature means trees and plants can capture carbon dioxide, reduce global warming, and regenerate biodiversity.
A 5.3-million-year-old deep-sea whale necropolis in the Diamantina Zone
Abstract Whale falls are biodiversity oases at seabeds1,2,3,4,5,6, yet their record from the oceans has remained sparse and fragmentary6,7. Here we report the discovery of a vast whale necropolis in the Diamantina Zone (4,616- to 7,001-m depth), extending about 1,200 km along the sea floor of the southeastern Indian Ocean. This area has a deep and extensive accumulation comprising five modern natural whale-fall communities and 476 fossil cetaceans recorded.
Gene ancestries reveal diverse microbial associations during eukaryogenesis
Abstract The origin of eukaryotes remains a central enigma in biology1. Continuing debates agree on the pivotal role of a symbiosis between an alphaproteobacterium and an Asgard archaeon2,3. However, the nature, timing and contributions of other potential bacterial partners4,5,6 and the role of interactions with viruses7,8,9 remain contentious.
Whole-genome duplication shaped cell-type evolution in the vertebrate brain
Abstract The complex brains of vertebrates have more cell types than those of their closest relatives. Whole-genome duplications (WGDs) occurred during early vertebrate evolution1, but it is unclear whether the duplicated genes (ohnologues) facilitated cell-type evolution. Here using brain single-cell transcriptomes from five chordates—human2, mouse3, lizard4, lamprey5 and amphioxus—we report that many cell-type families with conserved core transcription factors in vertebrates do not show...
