A new gel developed by McGill researchers could change how vocal cord injuries are treated. The injectable material lasts far longer than current options, staying intact for weeks instead of breaking down quickly. By acting like a molecular glue, it ...

Dry eye disease affects millions of people, causing burning, redness, and constant eye fatigue that can worsen over time. Scientists now believe the problem may begin deep inside tear glands, where a vital cellular cleanup process fails to function . ...

Attention depends on the brain's ability to filter out distractions, but new research suggests this works best when background brain activity is quieter. Scientists found that lowering certain versions of the Homer1 gene improved focus in mice by ...

Scientists are uncovering new clues that a cosmic explosion may have rocked Earth at the end of the last ice age. At major Clovis-era sites, researchers found shocked quartz--evidence of intense heat and pressure consistent with a comet airburst ...

Moss may look insignificant, but it can carry a hidden forensic fingerprint. Because different moss species thrive in very specific micro-environments, tiny fragments can reveal exactly where a person has been. Researchers reviewing 150 years of ...

A new study suggests the vagus nerve may be one of the heart's most important defenders against aging. Researchers found that keeping this nerve connected to the heart helps protect heart cells and maintain strong pumping ability. Even partial ...

A new advance in bromine-based flow batteries could remove one of the biggest obstacles to long-lasting, affordable energy storage. Scientists developed a way to chemically capture corrosive bromine during battery operation, keeping its concentration ...

Astronomers tracking a nearby star system thought they had spotted an exoplanet reflecting light from its star. Then it vanished. Even stranger, another bright object appeared nearby. After studying years of Hubble Space Telescope data, scientists .. ...

A powerful 7.4-magnitude earthquake struck northern Chile in July 2024--and it wasn't supposed to be that strong. Unlike Chile's infamous shallow "megathrust" quakes, this one ruptured deep inside the Earth, where shaking is usually weaker at the ...

Being active boosts your daily calorie burn more than previously thought. Researchers found that increased physical activity raises total energy use without triggering the body to conserve energy elsewhere. Basic functions keep running at full speed, ...
