Some firefighter gear is manufactured with chemicals called brominated flame retardants that could pose a risk to firefighter health, according to a study published in Environmental Science & Technology Letters.
Large phytoplankton blooms north of the Hawaiian Islands have been seen in satellite imagery as vast swirls of color nearly every summer, but their origin and ecosystem dynamics have remained mysterious.
The ultimate goal of materials scientists is to design and create materials with precise structures and tailored properties. Predictive technologies have advanced significantly with the rise of AI, yet the delicate nature of chemistry, where even the smallest change can alter a
A rare, ultra-long earthquake in Myanmar revealed that mature faults can deliver their full force directly to the surface. The discovery could mean stronger shaking near faults like California’s San Andreas than current models predict.
This week marks the last chance for backyard astronomers to see interstellar Comet 3I/ATLAS before it races on its journey back to outer space
South Africa is home to some of the oldest evidence of life on Earth, contained in rocky, often layered outcroppings called microbialites. Like coral reefs, these complex "living rocks" are built up by microbes absorbing and precipitating dissolved minerals into solid formations.
Using satellite imagery and government data, researchers measured a 5% increase in voluntary, or non-subsidized, cover crop adoption by Arkansas farmers.
Satellites in orbit would begin to collide in a matter of days if they lost manoeuvrability during a solar storm or other outage
It's serious business for the world establishing a framework to limit the impact of climate change, but for some, market responses to the annual United Nations Conference of Parties (COP) climate negotiations are also a chance to make some serious money.
Compact, mixed-use districts are often assumed to naturally produce cleaner travel patterns, but the reality on the ground is far more complex.
Black youth in the United States disproportionately experience fatal drowning at rates up to five times higher than their white peers. These statistics relate to historical and structural barriers Black youth face in learning to swim.

Disruptions in interoception may underlie anxiety, eating disorders, and other mental health ailments
These three disorders could really be “CKM syndrome,” which can be treated with drugs like Ozempic
The sex of many turtles, crocodilians, and other reptiles is determined by the temperature at which their eggs incubate. Global warming could doom them
High on ayahuasca, Bruce Damer saw how life on Earth began. He may very well be right. The post The Psychedelic Scientist appeared first on Nautilus .
A new genetic mapping strategy reveals how entire networks of genes work together to cause disease, filling in the missing links left by traditional genetic studies. The technique could transform how scientists identify drug targets for complex conditions.
Nepal launched on Tuesday a nationwide tiger census, a key step in conservation efforts to aid the recovery of the big cats that once faced near extinction in the Himalayan nation.
Two dozen Kemp's ridley sea turtles are rehabilitating in Florida after the frigid waters off of Cape Cod, Massachusetts, left them struggling with frostbite, pneumonia and abrasions.
A newly developed AI can predict which diseases specific genetic mutations are likely to cause, not just whether they are harmful. The breakthrough could speed up diagnoses and open new paths for personalized treatment.
The rings of Saturn are normally thought to be flat, but measurements by the Cassini spacecraft show that some of their particles fly hundreds of thousands of kilometres above and below the thin main discs
Climate change will shape everything about life in Australia—from the homes we live in and the food we grow to the risks of bushfires, floods, and heat waves. But what will that future look like? We can't know without climate models.
Christopher Rounds is a scientist who studies walleye in Minnesota, but he doesn't use a boat or a net or even a laboratory.
Women serving in the Indian Armed Forces suffer systemic discrimination across all stages of their military careers, a new study shows.
Professional footballer players who became injured while on their period took longer to recover than when injuries occurred at other times of their menstrual cycle
Around 1,000 years ago, a major climate shift reshaped rainfall across the South Pacific, making western islands like Samoa and Tonga drier while eastern islands such as Tahiti became increasingly wet. New evidence from plant waxes preserved in island sediments shows this
A new report warns Deaf women experiencing domestic abuse in Scotland remain "effectively invisible" due to the chronic absence of specialist services and a lack of coordinated national support. Researchers say this gap leaves deaf victim-survivors without meaningful access to
Giant mosasaurs, once thought to be strictly ocean-dwelling predators, may have spent their final chapter prowling freshwater rivers alongside dinosaurs and crocodiles. A massive tooth found in North Dakota, analyzed using chemical isotope techniques, reveals that some
Air pollution is the latest environmental crisis causing havoc across Iran. Large parts of the country are already suffering from a drought, one of the worst in decades. Its wetlands are dry, and its land is subsiding at alarming rates.
Congress appears poised to spend money in 2026 on beach replenishment projects in wake of the zero dollars it allocated this year.
New data released today from one of the world's longest-running wildlife surveys show Australia's waterbird population made a partial return after last year's steep drop, but numbers remain well below historic levels.

At the heart of every camera is a sensor, whether that sensor is a collection of light-detecting pixels or a strip of 35-millimeter film. But what happens when you want to take a picture of something so small that the sensor itself has to shrink down to sizes that cause the
People often see science as a world apart: cool, rational and untouched by persuasion or performance. In this view, scientists simply discover truth, and truth speaks for itself.
The water that flows down irrigation canals to some of the West's biggest expanses of farmland comes courtesy of the federal government for a very low price—even, in some cases, for free.
