Sea level on Earth has been rising and falling ever since there was water on the planet. Scientists were already able to use sediments and fossils to roughly reconstruct how sea levels changed over time steps of a million years or more. /news/2025-07-scientists-reconstruct-million-years-sea.html Earth Sciences Environment Mon, 07 Jul 2025 15:25:19 EDT news671120714 Fish make hanging motionless in the water column look effortless, and scientists had long assumed that this meant that it was a type of rest. Now, a new study reveals that fish use nearly twice as much energy when hovering in place compared to resting. /news/2025-07-fish-energy-resting.html Plants & Animals Ecology Mon, 07 Jul 2025 15:00:05 EDT news671101294 Across much of Europe, the engines of economic growth are sputtering.

On Tuesday, July 1, Kimalu, who was born at Shedd, underwent a first-of-its-kind surgery to remove a growing network of cysts near her blowhole on her head and neck. In the process, Kimalu became the first known beluga in the world to recover from general anesthesia. The surgery was supported by nearly 30 experts from Shedd and across the country in the fields of zoological medicine, surgery and anesthesia. /news/2025-07-aquarium-history-kind-procedure-kimalu.html Plants & Animals Veterinary medicine Thu, 03 Jul 2025 17:30:04 EDT news670780858 On March 25, 2025, a Turkish Ph.D. student at Tufts University, R眉meysa 脰zt眉rk, was walking in a Boston suburb when she was detained by plain-clothed federal agents.

Households with multiple cars might want to pack into more than one vehicle to save more possessions, but doing so risks causing traffic that can block firefighter access and endanger people, especially in neighborhoods with few exits and narrow roads. /news/2025-07-games-preparedness-community-resilience-wildfire.html Environment Wed, 02 Jul 2025 10:30:49 EDT news670671041 In recent years, with the public availability of AI tools, more people have become aware of how closely the inner workings of artificial intelligence can resemble those of a human brain. /news/2025-07-geometric-link-convexity-bridge-human.html Mathematics Wed, 02 Jul 2025 05:00:05 EDT news670604634 An unexpectedly strong solar storm rocked our planet on April 23, 2023, sparking auroras as far south as southern Texas in the U.S. and taking the world by surprise. /news/2025-07-nasa-missions-severity-solar-storms.html Planetary Sciences Tue, 01 Jul 2025 17:07:04 EDT news670608421 While the current generation of artificial intelligence chatbots still flub basic facts, the systems answer with such confidence that they're often more persuasive than humans. Adults, even those such as lawyers with deep domain knowledge, still regularly fall for this.

The cells communicate with one another during this process through cell-surface receptors, which interact with proteins outside the cell to trigger processes within the developing embryo's cells at specific times and places. However, the detailed molecular mechanisms behind how cells communicate during early embryonic development are not yet fully understood. /news/2025-07-unique-cell-receptor-interactions-essential.html Cell & Microbiology Molecular & Computational biology Tue, 01 Jul 2025 11:51:04 EDT news670589461 For centuries, Korea has stood at the heart of fermentation culture.

The Piscatorial Atlas, authored by Ole Theodor Olsen and published in 1883, contains 50 beautifully illustrated charts of the seas around Great Britain. These show the locations exploited at that time for a variety of fish species, alongside the typical vessels or fishing gear used. This information was collated from fishermen in the decade before the atlas was published. /news/2025-06-19th-century-atlas-marine-ecosystems.html Ecology Mon, 30 Jun 2025 10:10:07 EDT news670497002 Children's play is essential for their cognitive, physical and social development.

A coral reef is punctured at points by reef passes鈥攚ide channels that cut through the coral and serve as conduits for ocean water and nutrients to filter in and out.
