In a paper published this month in the journal Physical Review Letters, an international team of physicists described a new mechanism of dark matter production. Baker et al. described a new mechanism of dark matter production: if dark matter particles acquire mass during a first order phase transition, it is …

The so-called self-interacting dark matter theory helps explain why NGC 1052-DF2 and NGC 1052-DF4, a pair of ultra-diffuse galaxies located approximately 65 million light-years away the constellation of Cetus, contain little dark matter. The NASA/ESA Hubble Space Telescope took this image of NGC 1052-DF2 on November 16, 2017. Image credit: …

There are at least 200 ranking factors in Google’s algorithm (not to mention RankBrain), which means a thorough SEO audit could lead to dozens, hundreds, or even thousands of SEO tasks. Few companies have the budget or resources to complete every potential SEO to-do item — and doing so would …

Two teams of physicists have independently created a mysterious new state of matter. The state is known as a supersolid and it combines the properties of both solid and superfluid states. Illustration of a supersolid state, in which the properties of a frictionless fluid and a crystalline state coincide. Image …

High keyword rankings are the most sought-after achievement in the world of search engine optimization (SEO). Small businesses and brands alike strive to obtain the first organic listing in search results because of the lucrative traffic and lead opportunities that are associated with this position. But with the evolution of paid …

Dutch string theorist Dr. Erik Verlinde insists on saying gravity doesn’t exist. The good professor clearly does not believe that if he stops holding onto his briefcase, it will do anything other than fall. But he definitely believes we’re thinking of it all wrong. And if it turns out he’s right, …

When we reach the age of 70 ½ we must — in order to avoid tax penalties — take Required Minimum Distributions (RMD s) from IRAs, 401ks and other types of tax advantaged accounts — all  retirement accounts funded with pre-tax contributions. So what exactly is a “Required Minimum Distribution?” Let’s …

Just five breaths in downward dog felt like an eternity for Dana Falsetti when she first started attending yoga classes in 2014. “I remember feeling really defeated…. I think that’s a common thing for any beginner,” she says. Her shoulders felt weak attempting to hold her bodyweight — and her …
