The full moon is seen ahead of a total lunar eclipse, known as the “super blood

Lake Mercer, a subglacial lake deep below the Antarctic Ice, sat untouched by humans for millennia – until now. Scientists accidentally discovered the lake in 2007, when they were examining satellite imagery of Antarctica’s ice sheet. Then on December 26, 2018, they finally reached it. To explore the 50-foot-deep subglacial lake, researchers from a project called SALSA

The world is going to run out of food. Don’t worry, the best minds are on it. They are using better seeds, lighting and irrigation systems to reimagine farming. They are also using robots.

A decade ago, when Medicare beneficiaries were discharged from hospitals, one in five returned within a month. Older people faced the risks of hospitalization all over again: infections, deconditioning, delirium, subsequent nursing home stays. And preventable readmissions were costing Medicare

Announced by the LIGO collaboration in February 2016, the discovery of ripples in spacetime known as gravitational waves was momentous enough to merit the 2017 Nobel Prize in Physics.

For the longest time the cerebellum, a dense, fist-size formation located at the base of the brain, never got much respect from neuroscientists. For about two centuries the scientific community believed the cerebellum (Latin for “little brain”), which contains approximately half of the brain’s neurons, was dedicated solely to the control of movement. In recent

Some human body parts serve no purpose despite once having a specific function among our ancestors. The appendix, for example, is not an essential body part (though some research suggests it may act as storage for good bacteria). In some cases, the appendix gets inflamed or ruptures, which requires surgical removal of the organ. Several
