Drones that put selfie sticks to shame, pollution zapping air filters, 3D printable airless tires and a malware detecting router for your smart home.

SmileDirectClub offers to straighten your teeth at a fraction of the cost of braces, without a visit to the dentist. But orthodontists claim the company has endangered the oral health of tens of thousands of people.

By 2020, 45 million Americans will be caring for 117 million seniors. The retailer offers a $29 monthly monitoring service using internet-connected gear.

Researchers at MIT have developed deep-learning algorithm that can compile a list of ingredients and even recommend recipes after looking at photos of food. The artificially intelligent system still needs some fine tuning, but this tool could eventually help us learn to cook, count calories, and track our eating habits.

Building a home or temporary shelter by hand can be both time-consuming and expensive. Ten Fold Engineering, a housing startup based in the UK, has created self-deploying buildings that can pop up in a matter of eight minutes.

Starting as a niche technology, 3D printing has been around for a long time. And talk of how this technology could transform the construction industry, largely theoretical, has long circulated, too. But now, thanks to young entrepreneurs Chris Kelsey and Fernando De los Rios, we can expect to see 3D printing robots on building sites […]

From smart TVs to a modular sofa that can be controlled by an app, home tech isn’t just something for the future, it’s in our homes now. New technologies aim to make our lives easier, safer, and—sometimes—a little bit cooler.

Tim Berners-Lee, who invented the World Wide Web, now wants to save it. The computer scientist who wrote the blueprint for what would become the World Wide Web 28 years ago today is alarmed at what has happened to it in the past year. “Over the past 12 months, I’ve become increasingly worried about three new […]

As we start to 3D-print everything — including houses, of all things — it’s pretty impressive that a company built one in just 24 hours. Located in Russia, this 400-square-foot home (37 square meters) was built in just a day, at a cost of just over $10,000.
