There is nearly 16,700 cubic feet of habitable area aboard the International Space Station (ISS). That makes it larger than a six-bedroom, two-bathroom house,but still small enough for a grand tour that takes less than 15 minutes. That doesn’t mean there’s nothing worth seeing. Far from it, actually. Earlier this month, NASA released a high-definition video showcase of the ISS, its facilities, and its crew recorded during the Crew-4 and Crew-5 missions in October 2022. The guided tour begins in the Columbus Laboratory Module—the European Space…

Sarah Sajedi was visiting Phi Phi Island, Thailand, when she was dazzled by the beautiful scenery of the Andaman Sea. However, when she looked down at her feet, she saw that the white sandy beach was covered with plastic debris, most of which was from plastic bottles.After many years in the business world as the cofounder of an environmental software company, the experience inspired Sajedi to become a researcher. She had always had a passion for waste reduction, but she realized that the problem was consumption itself.Thus, as a doctoral student at Concordia University in Canada, Sajedi reviewed over 140…

Drop into the lagoon in Donkey Kong Bananza. Sure, you need to chase Void Kong to the Earth’s center to save the day, but maybe you just want to soak in some water-adjacent locales as you explore this new world beneath the surface. There are plenty of secrets tucked away in each level’s hidden crevices. When you first hop in there is really only one thing to do: pick a direction and start smashing.Donkey Kong Bananza takes Nintendo’s hallmark sandbox exploration and pushes it somewhere the studio rarely goes–pure chaos.

A new telescope can be a doorway to the universe — that is, until you actually take it outside and nothing looks the way you imagined it. Telescopes aren’t necessarily difficult to use, but they do require a little preparation, a bit of patience and an understanding of how the night sky moves.If your first few sessions have been more frustrating than awe-inspiring, you’re not alone. Here are five of the most common mistakes, plus how to avoid them so you can spend less time fiddling and more time actually enjoying the view.1. Neglecting the planning stage Sky maps and…

Two things I always watch for with supplements, even with guidance from my doctor: Does it have a CGMP certification, and is there any data to back up the marketing claims? CGMP stands for “Current Good Manufacturing Process,” which are FDA guidelines put in place for a product’s safety. This includes where and how it was made, as well as what it was made of. But even with this kind of baseline, it’s hard to tell what additives are used in a supplement and how that can counteract its effects or react with your body chemistry.So, Can I Take Melatonin…

By beaming an ultra-low-latency live feed from its camera directly into a pair of goggles, a first-person view (FPV) drone puts you right in the cockpit of a small and agile aircraft able to squeak through the smallest of gaps and pull off breathtaking moves like flips, barrel rolls, loops, and vertical plunges. These aren’t drones you buy to get pristine photos of wide-open vistas so much as to experience (and document) an adrenaline-inducing roller-coaster ride through a tight, obstacle-populated environment.As such, piloting an FPV drone is a completely different, entirely more challenging kettle of fish than piloting a standard…
