Uranus is a lopsided oddity, the only planet to spin on its side. Scientists now think they know how it got that way: It was pushed over by a rock at least twice as big as Earth...

Whether genetic changes can be reversed or are passed on to children is still unknown. New research from Duke Health suggests men in their child-bearing years should also consider how THC could impact their sperm and possibly the children they conceive during periods when they’ve been using the drug...

Chloride-free electrolyte and organic cathode boosted energy density, stability. Researchers from the University of Houston and the Toyota Research Institute of America have discovered a promising new version of high-energy magnesium batteries, with potential applications ranging from electric vehicles to battery storage for renewable energy systems.

The battery, reported Dec. 21 in Joule, is the first reported to operate with limited electrolytes while using an organic electrode, a change the researchers said allows it to store and discharge far more energy than earlier magnesium batteries...

Eat your spinach in the form of a smoothie or juice – this is the best way to obtain the antioxidant lutein, according to research from Linköping University, Sweden. High levels of lutein are found in dark green vegetables, and researchers at the university have compared different ways of preparing fresh spinach in order to maximise the levels of lutein in finished food. The findings are published in the journal Food Chemistry.

Many people with atherosclerosis (narrowing of the arteries) have low-grade, chronic inflammation that can be measured in the blood...
