In the depths of the Pacific Ocean, a hydrothermal vent that the remotely operated vehicle (ROV) named SuBastian explored in early March is a remarkable sight to see. At a depth devoid of light, creatures and microbes thrive off of the chemicals spewing from deep inside the Earth. Over time the chemicals accumulate around the vent to build mineral towers, some upwards of 60 feet tall (20 meters), like upside down stalactites spotting the landscape.

Dark energy is without a doubt the weirdest thing in the universe. Despite being present in every corner of the cosmos and dominating its evolution, dark energy is so far outside our best existing theories of physics that we're still trying to figure out if it's something in the universe or just a basic property of space itself.

The notion that Mars once hosted an ancient, watery ocean is intellectually seductive. Not only does it make the Red Planet seem much more like our own, it raises hopes for finding evidence of hypothetical life that once swam the Martian seas.

Diets for weight loss usually involve restriction. The 5:2 diet relies on restricting calories, and the ketogenic diet relies on restricting particular types of food.Research suggests, however, that restrictive dieting can lead to a higher body mass index (BMI) over time and a greater future likelihood of being overweight.

For over fifty years, scientists have theorized that roughly 85% of matter in the Universe's is made up of a mysterious, invisible mass. Since then, multiple observation campaigns have indirectly witnessed the effects that this Dark Matter has on the Universe. Unfortunately, all attempts to detect it so far have failed, leading scientists to propose some very interesting theories about its nature.

Many of the great advances in science are marked by the discovery that an aspect of nature we thought was fundamental is actually an illusion, due to the coarseness of our sensory perceptions. Thus, air and water appear to us to be continuous fluids, but we discover on deeper experiment that they are made of atoms.

For decades, statisticians and clinicians have debated the meaning of statistical and clinical significance. In general, most journals remain married to the frequentist approach to statistical testing and using the term statistical significance. A recent proposal to ban statistical significance gained campaign-level momentum in a commentary with 854 recruited signatories.
