For roughly 80 years, the United States has managed the threat of nuclear terrorism through nonproliferation treaties, agency programs, intelligence activities, international monitoring support and more, withstanding the Cold War, the fall of the Soviet Union, and 9/11.

A joint research team that included members from Tohoku University has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and semiconductors.

The hydropower dams on the Columbia River flooded villages, disrupted economies and ways of life and continue to harm people indigenous to the Pacific Northwest, according to a first-of-its-kind federal report released Tuesday.

A research paper from University of Vermont's Keller Laboratory examining the impacts of genomically-diverse seedlings on the resilience of red spruce forests in a changing climate was published in Applications in Plant Sciences.

The Sun Corridor in Arizona in the semi-arid Southwestern U.S. is a land of seeming unlimited growth that is constantly colliding with physical constraints. It is mountainous but also home to a large valley that includes one of the fastest growing metropolitan areas in the U.S.

More than 48,000 deer, thousands of Pacific newts, close to 100 mountain lions and many thousands of other animals are killed each year by vehicles on California roads, according to the 2024 "roadkill report" from the University of California, Davis' Road Ecology Center.

A new study led by the Virginia Tech's College of Agriculture and Life Sciences reveals that market-ready steers can maintain meat quality and yield even when fed lower-cost, low-input maintenance diets for longer periods than previously understood.

A late scrub due to weather on June 18 means it will have been at least 12 days since SpaceX last lit up the Space Coast sky with a rocket launch, the longest run between launches in more than a year.

Crews battling wildfires across California on June 18, including the Post fire in Los Angeles County, face another day of gusty winds and low humidity that will push flames into tinder-dry fuel, weather forecasters warned.

Astronomers from India and Thailand have observed a young nearby open cluster known as Berkeley 59. Results of the observational campaign, published June 12 on the pre-print server arXiv, deliver essential information regarding low-mass stellar and substellar content of this cluster.

Photonic alloys, alloy-like materials combining two or more photonic crystals, are promising candidates for the development of structures that control the propagation of electromagnetic waves, also known as waveguides. Despite their potential, these materials typically reflect light back in the direction where it originated.

Looking under the microscope, a group of cells slowly moves forward in a line, like a train on the tracks. The cells navigate through complex environments. A new approach by researchers involving the Institute of Science and Technology Austria (ISTA) now shows how they do this and how they interact with each other. The experimental observations and the following mathematical concept are published in Nature Physics.

Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.

A new study published in the journal Environmental Research Letters reveals that the environmental impact of the February 3, 2023, Norfolk Southern train accident in East Palestine, Ohio covered a very large geographical area. Inorganic pollutants released due to the accident were found in wet weather downfall (wet deposition) from the Midwest through the Northeast, reaching as far as southern Canada and North Carolina.

Conventional drug delivery is often like cracking a nut with a sledgehammer. Whether the drug is swallowed, injected, inhaled, or absorbed through the skin, it ultimately diffuses to most parts of the body, including those where it isn't needed—or where it might even cause harm.
