But new research from Saarland University reveals that this long-standing explanation is wrong. Instead, the slipperiness comes from the subtle interaction of molecular dipoles between ice and surfaces like shoes or skis. These microscopic electrical forces disorder the crystal structure of ice, creating a thin liquid layer even at temperatures near absolute zero. The discovery overturns nearly 200 years of scientific thought and has wide implications for physics and winter sports alike.

Its ancient, oxygen-poor atmosphere allowed the molecule to form, offering new insight into how planetary atmospheres evolve.

The findings reveal a persistent and little-known legacy of industrial dumping that still shapes marine life today.

These findings suggest that ancient Martian environments may have supported chemical processes similar to those on Earth, where microbial life thrives. While the team stresses they have not discovered evidence of life, the rocks show chemical reactions and mineral formations that could point to biological activity.

Using an "optical sieve" test strip viewed under a regular microscope, these particles reveal themselves through striking color changes.

Once introduced, these voracious predators climbed to the top of the food chain, forcing native fish like channel catfish and bass to shift diets and habitats. Using stable isotope analysis, researchers uncovered how the invaders disrupt food webs, broaden dietary overlaps, and destabilize energy flow across the river system. The findings show how a single invasive species can spark cascading ecological consequences.

By harnessing oxygen in the air as a natural oxidizer, the technique breaks down stubborn pigments such as beta carotene and lycopene, outshining hydrogen peroxide and even UV treatments.

A 15-year study of more than 2,400 older adults reveals that diets rich in vegetables, whole grains, nuts, and healthy fats slow the accumulation of diseases like cardiovascular problems and dementia—while inflammatory diets heavy in red meat and sugary drinks speed it up. Researchers now aim to pinpoint the most effective dietary recommendations to promote longer, healthier lives.

A study of nearly 4,000 European species reveals that tall, adaptable, nutrient-loving generalists dominate both at home and in foreign ecosystems.

These cyanobacteria drive 5% of Earth’s photosynthesis and underpin much of the marine food web. A decade of research shows they thrive only within a narrow temperature range, and warming oceans could slash their populations by up to 50% in tropical waters.
