Friends and family will come together to celebrate, share gifts and eat traditional foods as the eight-day Jewish festival of Hanukkah begins on Dec. 14, 2025.
The U.S. is largely self-sufficient in agricultural food production, supported by a well-developed storage and interstate trade system. However, extreme weather events put increasing pressure on agriculture, potentially impacting the country's ability to provide food for its
Some 4.6 billion years ago, Earth was nothing like the gentle blue planet we know today. Frequent and violent celestial impacts churned its surface and interior into a seething ocean of magma—an environment so extreme that liquid water could not exist, leaving the entire planet
Machine learning is transforming many scientific fields, including computational materials science. For about two decades, scientists have been using it to make accurate yet inexpensive calculations of interatomic potentials, that are mathematical functions that express the
Biphenomycins, natural products derived from bacteria, show excellent antimicrobial activity, but have long remained out of reach for drug development. The main obstacle was the limited understanding of how these compounds are produced by their microbial hosts.
A new study led by researchers from Saint Louis University, the Saint Louis Zoo, and partner organizations recently set out to understand how raccoons use space in one of the nation's largest urban parks.
China's tidal flats feed people and mollusk-eating migrating shorebirds such as red knots, great knots and Eurasian oystercatchers. Under good management, these flats used for aquaculture markedly reduce human disturbance on tidal wetlands.

Harvard researchers have discovered that cycads—one of the oldest living lineages of seed plants—heat up their reproductive organs to attract beetle pollinators and the insects possess infrared sensors to detect these signals.
When the early Earth’s magma ocean crystallized 4.4 billion years ago, the deep mantle trapped an ocean’s worth of water, scientists say.
New research on strange cycad plants offers a glimpse into the prehistoric origins of pollination
Proximity to green space provides a wide range of physical, mental, social and environmental benefits. By that measure, the Twin Cities—where 99% of all residents live within a 10-minute walk to a park—should be a model of equitable access to parks and the benefits they confer.
There is a dire need for selective catalysts that allow us to consistently achieve a desired outcome in a chemical reaction. It is this consistency that allows for more efficient, energy-saving ways of producing fuel. A team of researchers from Tohoku University, the Indian
Carbon capture is becoming essential for industries that still depend on fossil fuels, including the cement and steel industries. Natural-gas power plants, coal plants, and cement factories all release large amounts of CO₂, and reducing those emissions is difficult without
