Researchers found rerouting container ships and oil tankers around whale shark hotspots used at most one percent more fuel on longer voyages. For shorter crossings, restricting vessels' speed was more fuel efficient, with costs limited to less than one percent.
A new technique harnesses microscopic dislocations as shock absorbers to toughen aluminum-steel joints. The method, which involves a simple heat treatment and rapid cooling process, increases joint strength by 80.3% and fracture toughness by 70%.
The book explores how offshore finance centers in the Caribbean exploit island territories' colonial state of exception, maintaining global capital's dominance. It reveals how corporate citizens and wealthy individuals wield increased secrecy and power, while ordinary citizens face increased surveillance and exclusion.
A systematic review maps generative AI models and their applications in medicine, highlighting challenges and future directions. The review proposes developing uncertainty quantification and explainable AI to build trustworthy generative AI systems for medical professionals.
Scientists have identified a distinctive chemical fingerprint preserved in rocks from around the world that pinpoints a major shift in Earth's geological record about 2.5 billion years ago. This finding helps explain when Earth acquired one of the features that sets it apart from tectonically inactive planets.
New research reveals that clownfish prioritize defending and maintaining their anemone homes over social cohesion during bleaching events, leading to increased defensive behavior and aggression among group members. This crucial mutualism between anemonefishes and anemones plays a vital role in recovery from bleaching.
A study published in Nature Mental Health identified three distinct brain biotypes in children with ADHD and anxiety, characterized by malfunctions in specific brain circuits. These biotypes may help clarify the overlap between ADHD and anxiety and provide new therapeutic targets.
Chronic stress activates the hypothalamic-pituitary-bone marrow axis, leading to immunosuppression and tumor growth. Pharmacological blockade of the melanocortin 1 receptor restores antitumor immunity and enhances programmed cell death protein 1 checkpoint inhibition.
