Interval running condenses the powerful effects of regular running into shorter, high-intensity bursts. Research shows it can improve cardiovascular health, regulate blood sugar, and reduce body fat more effectively than longer steady runs. Just a few short sprints per session can deliver major fitness gains.

Running offers a wide range of advantages for both body and mind. It can protect against disease, improve mood, and even slow down the body’s natural aging process.

Yet about 31% of adults still don’t get enough physical activity, including running. The most common reason people give is simple — they don’t have enough time.

That’s where interval running comes in. It promises nearly all the same benefits of regular running, but in a fraction of the time.

An international team of astronomers has created the first-ever large-scale maps of a mysterious form of matter, known as CO-dark molecular gas, in one of our Milky Way’s most active star-forming neighborhoods, CygnusX. Their findings, using the Green Bank Telescope (GBT), are providing crucial new clues about how stars formed in the Milky Way.

For decades, scientists have known that most new stars are born inside clouds of cold molecular hydrogen gas. Much of this molecular hydrogen is invisible to most telescopes—it doesn’t give off light that can easily be detected.

Traditionally, astronomers have hunted for these clouds by looking for carbon monoxide (CO), a molecule that acts like a flashing sign for star-building regions...

Adults with gum disease may be more likely to have signs of damage to the brain’s white matter, called white matter hyperintensities, than people without gum disease, according to a study published in Neurology Open Access.

White matter refers to nerve fibers that help different parts of the brain communicate. Damage to this tissue can affect memory, thinking, balance and coordination and has been linked to higher stroke risk.

White matter hyperintensities are bright spots that appear on brain scans that are thought to reflect damaged white matter tissue. While the study found an association, it does not prove that gum disease causes white matter damage.

“This study shows a link between gum disease and white matter hyperintensities, suggesting...

Spinning crystals that twist, shatter, and rebuild themselves may hold the key to next-generation materials.. Physicists have uncovered the fascinating world of “rotating crystals” — solids made of spinning particles that behave in strange, almost living ways. These odd materials can twist instead of stretch, shatter into fragments, and even reassemble themselves.

It may sound unbelievable, but crystals made of rotating particles are real. A group of physicists from Aachen, Düsseldorf, Mainz, and Wayne State University (Detroit, USA) has explored these unusual materials and their remarkable behavior. These crystals can easily split into separate fragments, form unusual grain boundaries, and display controllable structural defects...
