Andreypopov/Getty Images Wearable technology like smart rings and smartwatches allow you to track your fitness and health, helping you form better habits and make more informed decisions. There are many good wearable devices for sleep tracking, and in general, these devices provide reliable data about your personal sleep habits. This includes the time it takes to fall asleep, the time spent in different stages of sleep and how often you wake up at night, as well as biomarkers such as heart rate and blood oxygen level. But if you’re looking…

Danny Ye/Shutterstock The list of things you can build with 3D printing seems to grow every day. Many obscure sites offering 3D printing projects allow hobbyists to print their own miniatures and toys, and engineers can now 3D print objects of unexpected size, such as houses and replica skeletons. Recently, scientists invented a 3D printing technique that they believe could resurrect the dodo. But don’t expect to print yours with your home printer. Recently, Colossal Biosciences (the company trying to revive the woolly mammoth) designed what it claims to be…
Hadrian/Shutterstock Bringing your electronics closer to magnets can be scary. After all, if magnets can pull on other metal objects, they can be expected to damage your smartphone’s internal components as well. We’ve seen this with past technology, where placing a magnet near your old TV would distort the picture or completely magnetically erase the data on your hard drive. Fortunately, most modern consumer devices are very resistant to small, everyday magnets and can function properly even with a magnet directly affecting them. Apple has a support page covering the…

However, this misconception hardly applies to desktop monitors designed specifically for high-end PCs. In fact, OLED technology in general has come a long way. While there are certainly pros and cons, using an OLED monitor for gaming is a perfectly viable decision. But what if you want to make sure you’re getting the best display for your gaming…

They can be picky about their equipment and already have many obvious accessories. This eliminates must-have options like camera bags, memory cards, and camera straps, making finding something thoughtful, useful, and within a reasonable budget an even bigger challenge. What makes things even more complicated is that cameras and lenses are incredibly expensive, and it’s not particularly easy to guarantee that you’re buying gear that’s compatible with what the photographer in your…
Simpson33/Getty Images 4K resolution is a mainstream TV specification that has been pushing pixels for over a decade. But if you’ve bought TVs in recent years, you’ve probably seen “4K” and “UHD TV” used to describe a pixel count that exceeds 1080p HD (1,920 x 1,080), times four. Believe it or not, most 4K smart TVs on the market don’t have true 4K displays, and that’s because manufacturers decided to do some rounding off. Initially, 4K picture technology was only used for digital cinema projection, where the pixel count was…

Many of the best models offer a wide range of cleaning features and robust add-on apps that let you customize everything, from when and where your robot vacuum cleaner cleans to the suction power it uses. At one time, robot vacuums were a boutique investment, but modern robots are much cheaper than their OG ancestors. Still, it’s not uncommon to find a premium Roomba…
Sombat Muycheen/Shutterstock Installing a security camera is an effective yet simple way to make your home more secure. While a camera can theoretically help you identify criminals who decide to target your property, ideally, the presence of a security camera can deter criminals in the first place. However, you need to choose the right security camera for your goals and needs. This involves making some key decisions, like choosing between a wired or wireless security camera. Each option has its own set of advantages and disadvantages. Your goal is not…
Stenko Vlad/Shutterstock 3D printers are truly affordable in 2026, with some entry-level machines now dropping to just a few hundred dollars. That said, even at this price, whether a 3D printer makes financial sense is a complicated question. For businesses, manufacturers who print regularly, or people who need custom parts on demand, the value proposition is much stronger and the purchase is likely worth it. 3D printing can reduce your reliance on retail parts and can be a boon for long prototyping cycles that become prohibitively expensive with traditional manufacturing.…
China is trying to solve its water- and energy-consuming data centers by moving them under the sea. Shanghai Hailanyun Technology (HiCloud), working with several government agencies, launched what it calls the world’s first wind-powered underwater data center in May 2026. It lies about 32 feet below the ocean surface, off the coast of Shanghai’s Lin-gang Special Zone, surrounded by a wind farm of more than 50 turbines. It hosts approximately 2,000 servers, which constitutes a small to medium-sized data center. Larger hyperscale data centers can accommodate at least 5,000 servers. At full capacity, the…
