Some benefits of Exercise stem from the Immune System, suggests new study

The connection between exercise and inflammation has captivated the imagination of researchers ever since an early 20th-century study showed a spike of white cells in the blood of Boston marathon runners following the race.

Now, a new Harvard Medical School study published in Science Immunology may offer a molecular explanation behind this century-old observation.

The study, in mice, suggests that the beneficial effects of exercise may be driven, at least partly, by ...

While Rare, why do Batteries sometimes Catch Fire and Explode?

While rare, why do batteries sometimes catch fire and explode?
3D microtomography experiments at the Advanced Light Source enabled researchers to pinpoint which particles generated current densities as high as 25 milliamps per centimeter squared inside a resting battery after fast charging. In comparison, the current density required to charge the test battery in 10 minutes was 18 milliamps per centimeter squared. Credit: Nitash Balsara and Alec S. Ho/Berkeley Lab

How likely would an electric vehicle battery self-combust and explode? The chances of that happening are actually pretty slim: Some analysts say that gasoline vehicles are nearly 30 times more likely to catch fire than electric vehicles...

Scorching, Seven-Planet system revealed by New Kepler Exoplanet list

Artist’s concept showing two of the seven planets discovered orbiting a Sun-like star. The system, called Kepler-385, was identified using data from NASA’s Kepler mission.

A system of seven sweltering planets has been revealed by continued study of data from NASA’s retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system. Also unlike any of our immediate neighbors, all seven planets in this system, named Kepler-385, are larger than Earth but smaller than Neptune.

It is one of only a few planetary systems known to contain more than six verified planets or planet candidates...

‘Super Melanin’ Heals Skin Injuries from Sunburn, Chemical Burns

Imagine a skin cream that heals damage occurring throughout the day when your skin is exposed to sunlight or environmental toxins. That’s the potential of a synthetic, biomimetic melanin developed by scientists at Northwestern University.

In a new study, the scientists show that their synthetic melanin, mimicking the natural melanin in human skin, can be applied topically to injured skin, where it accelerates wound healing. These effects occur both in the skin itself and systemically in the body.

When applied in a cream, the synthetic melanin can protect skin from sun exposure...
