By studying the way it has mutated and changed over time, scientists can trace human mitochondrial DNA — the DNA that is passed from mother to daughter — back to a single woman.

Whether or not you've ever found yourself arguing this point with a family member or friend, the piece is really useful for deepening your understanding of a pop-science concept that's often thrown around without a clear explanation behind it.
Researchers successfully revived ancient microbes, some more than 100 million years old, that were buried in the seafloor. During an expedition to the South Pacific Gyre, the scientists from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and their colleagues drilled into the ocean sediment almost 6,000 meters below the surface. “Our main question […]

Then in May, the Center for Disease Control and Prevention clarified its own Web page about how COVID-19 spreads to state that “based on data from lab studies on COVID-19 and what we know about […]
You may not realize it, but some of the biggest films in movie history have been edited using the same tools some of you use to cut your video of vacationing at Disney World. Giant movies from Oscar favorites The Social Network and Gone Girl to blockbusters like Avatar, Deadpool, and last year’s Terminator: Dark […]
Now that the initial furor and shortages have subsided, it’s probably not a bad time to start considering your long-term cleaning and disinfecting plans. Sure, that might seem anywhere from overly cautious to outright ridiculous, but the threat of COVID-19 appears poised to be present for a while and the need for quick travel clean-up […]
With more and more companies moving all their operations into the cloud, the need has never been greater for those with the skills to map exactly how an organization reconstitutes itself in that new environment. Network architects responsible for determining all the communication, storage, and infrastructure needs of an expansive organization are among the most […]
