Astronomers have revealed the sharpest image ever captured of a filament in the cosmic web — the enormous hidden structure connecting galaxies across the Universe. The glowing strand stretches 3 million light-years and links two galaxies from nearly 12 billion years ago...

People who carry the APOE2 version of the apolipoprotein E gene are more likely to live to advanced age and are partly protected against Alzheimer’s disease, but scientists have struggled to explain why...

Our solar system is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron produced in stellar explosions. This has now been confirmed by an international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) through the analysis of Antarctic ice tens of thousands of years old...

A supplement widely promoted for athletic performance may interfere with some of the heart’s beneficial adaptations to exercise, according to new Dalhousie University research published in Scientific Reports.

While these supplements are often promoted to support exercise performance and cardiovascular function, researchers found the combination of sodium nitrate and running prevented several beneficial cardiac improvements normally associated with exercise in females.

Those benefits included changes linked to heart structure, ventricular function and calcium handling in heart cells, which helps regulate contraction and relaxation...
