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…

Just above this melee is the quieter constellation Perseus, which lacks…

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…

Compare Our PicksOthers TestedCourtesy of Sakara LifeSakara Life; starts at $141 per week; up to $465 for specialty programs: This plant-based, gluten-free meal kit reminds me of what most people think when they think of “crunchy” vegan food—raw vegetables with an earthy taste. Nearly all meals in Sakara’s lineup are uncooked and preprepared—items like veggie burgers are without buns, lasagnas are “deconstructed.” For example, a “Lavender Quesadilla” has broccoli pesto and cashew “cheese” with hibiscus salsa … you get the idea.

One enormous cloud responsible for forming half of the stars in the Milky Way’s central region is the Sagittarius B2…

When Sam Altman said one year ago that OpenAI’s Roman Empire is the actual Roman Empire, he wasn’t kidding. In the same way that the Romans gradually amassed an empire of land spanning three continents and one-ninth of the Earth’s circumference, the CEO and his cohort are now dotting the planet with their own latifundia—not agricultural estates, but AI data centers.Tech executives like Altman, Nvidia CEO Jensen Huang, Microsoft CEO Satya Nadella, and Oracle cofounder Larry Ellison are fully bought in to the idea that the future of the American (and possibly global) economy are these new warehouses stocked with…

The human body is extraordinarily complex, with several openings and a few exits. But exactly how many holes does each person have?It sounds like a simple enough question to answer — list the openings and add them up. But it’s not quite that easy once you start considering questions like: “What exactly is a hole?” “Does any opening count?” And “why don’t mathematicians know the difference between a straw and a doughnut?”Before we start counting, we need to agree on what constitutes a “hole.” Katie Steckles, a lecturer in mathematics at Manchester Metropolitan University in the U.K. and a freelance…

2026 will be the year when US dollar dilution—the quiet erosion of its global dominance as countries trade and pay in alternatives—starts to build momentum. The more Washington uses the dollar as a weapon, the more the world builds ways to circumvent it.America’s share of global trade has fallen from one-third in 2000 to just one-quarter today. As emerging economies trade more with each other, the dollar is less central to the flow of goods. Indian and Russian trade now settles in rupees, dirhams, and yuan. More than half of China’s trade now moves through CIPS, China’s own cross-border payment…
