Remarkable backyard footage captures giant solar prominence and streams of coronal rain flowing along the sun's magnetic field lines.

From massive firework displays to grocery store banners. The post 13 incredible photos of America’s 1976 bicentennial celebration appeared first on Popular Science.

New simulations show that interactions with a magnetic field can work to decrease the distance between still forming binary protostars. These results can help explain the characteristics of the binary star systems observed in the Milky Way. The results can also be extrapolated to binary black holes, giving insights into how supermassive black holes evolve.

A seven-year collaborative study has revealed alarming fluctuations in the health of Hawaii's endangered insular false killer whales, with some individuals losing nearly a quarter of their body weight in just a few months. Published in Endangered Species Research, the findings provide the first quantitative evidence that nutritional stress and environmental shifts may be driving the decline of this iconic population, which now numbers fewer than 140 individuals.

Scientists have identified genetic variants that may make some people less responsive to GLP-1 drugs used to treat Type 2 diabetes. Roughly 10% of the population carries these variants, which appear to cause a mysterious form of "GLP-1 resistance." In several clinical trials, carriers were significantly less likely to reach healthy blood sugar targets while taking GLP-1 medications.

Fire salamanders—one of Europe's most well-researched amphibians—are biofluorescent, which means they can absorb light from an external source at one wavelength, then re-emit it at another

India gained around 2.1 million hectares of tropical dry woodland between 2014 and 2024—an area larger than Wales—according to a major new study involving researchers from The University of Manchester's Global Development Institute. The research was published in the journal Environmental Research Letters.

Three planets, two stars and one moon create a spectacular June sky show.

In the canals, wetlands and marshes of the Florida Everglades, the spectacled caiman has quietly expanded its foothold, threatening an already-vulnerable ecosystem. A new University of Florida study published in Frontiers in Amphibian and Reptile Science synthesizes more than 70 years of research on the invasive species native to Central and South America that has firmly established itself across the most vulnerable part of the Sunshine State—the Florida Everglades.

Octopuses may be even smarter than we thought. Researchers at Dartmouth found that octopuses can learn to use mirrors to locate food hidden behind them—a skill previously seen only in vertebrates like mammals and birds. After training, the animals correctly identified the food’s location about 73% of the time, showing they could use a mirror as a tool rather than simply reacting to a reflection.

A team of archaeologists and filmmakers got permission to dive in the closed zone of the Nassau harbor and discovered six wrecks, including three with suspected ties to the era of piracy

Researchers from Imperial College London have conducted the U.K.'s largest-ever longitudinal study of indoor fungal air pollution, revealing that homes are active fungal ecosystems rather than passive recipients of outdoor air. The West London Healthy Home and Environment Study (WellHome), led by researchers from Imperial's School of Public Health, analyzed the air in 118 households over a two-year period. The study focuses on children with asthma or allergies and families from ethnic minority groups and lower socio-economic backgrounds.

In a poignant pattern, many of the most important contributions to suffrage were enacted—or inspired—by mothers
