How did a sandal that originally entered the U.S. market as a health product become a fashion staple and the crowning shoe of a multibillion dollar company? Margot Fraser originally brought Birkenstocks to the U.S. thinking that the comfort of the German sandal would appeal to women. But she couldn’t get shoe stores to sell them. They finally made it into the U.S. market through health food stores. Now, the seductively ugly shoe is a cultural icon and was valued at about $8.6 billion when...

How does your doctor know that a drug or procedure will work to treat a condition before they try it? Often, they don’t. Researchers are looking to create “digital twins,” digital versions of individual organs, to see how a patient will respond. Eventually there could be digital twins of entire bodies that are updated in real time with patient data. WSJ’s Alex Ossola speaks with WSJ senior special writer Stephanie Armour about how that might change the way we treat diseases in the...

Ultrasound is known for its use in imaging during pregnancy. But new advancements in the technology suggest that in the future, ultrasound could be used to disrupt the blood-brain barrier. This would allow doctors to more easily diagnose and directly treat illnesses like brain cancer without major surgery. WSJ’s Danny Lewis and Charlotte Gartenberg examine the new ways that ultrasound could be used more specifically and subtly to deliver accurate diagnoses and precise treatments. What do...

A day when people can interact directly with computers using their thoughts could be on the horizon. Several companies, including Elon Musk’s Neuralink, have begun preliminary human trials of brain-computer interfaces - devices that decode the electrical signals in their brain and translate them into digital bits. Neurosurgeon Benjamin Rapoport is a co-founder and chief science officer of Precision Neuroscience, a company working on brain-computer interfaces. He spoke with WSJ’s Danny Lewis...

What does the brick and mortar bookstore of the future look like? For Barnes & Noble, it looks more like the indie bookstores they once threatened to put out of business 20 years ago.

The biggest U.S. commercial airlines have now gone 15 years without a fatal crash. So, how did hurtling through the sky in a giant metal tube become this safe? WSJ columnist Ben Cohen speaks with former FAA and International Civil Aviation Organization executive William Voss about the voluntary self-reporting programs that made flying the safest form of travel and asks if...

After years of promises that driverless cars were just over the horizon, one of the industry's biggest players is headed for the freeway. Now, for the first time, Alphabet’s Waymo is allowing robotaxis to take its employees on high-speed roads in Phoenix, Arizona without a human driver. The move comes just as the industry is facing a harsh reality after high-profile crashes: GM’s Cruise had its permits to operate driverless robotaxis pulled by the California DMV, and Waymo issued its...

Imagine driving down a road that recharges your electric car as it moves. Companies around the world are experimenting with new technology that can wirelessly charge EVs while they drive, thanks to copper coils buried beneath the asphalt. It could mean less time spent plugging in at slow chargers, no need for heavy, expensive lithium-ion batteries and wave goodbye to range anxiety. WSJ’s Danny Lewis reports on what it would take for this tech to hit the road, and how it could change the way...

In recent months, an Alaska Airlines jet lost a door plug mid-flight, and a Japan Airlines plane collided with another aircraft at an airport in Tokyo. Accidents like these are uncommon, but they could help engineers design safer airplanes. Embry-Riddle Aeronautical University associate professor Anthony Brickhouse tells WSJ’s Danny Lewis how advanced materials and computer systems could bring flight into a safer future, while making sure human pilots are still part of the equation. What...

Is it an earworm or an icon? The Super Mario Bros. theme is the soundtrack to many childhoods and has remained resonant today. Recently inducted into the Library of Congress’s National Recording Registry, the song was not easy to write.

AI voice assistants like Apple’s Siri and Amazon’s Alexa have become part of our everyday lives. But for people with atypical voices, including those with conditions like Parkinson’s disease and muscular dystrophy, these tools can be frustrating to use. Now a number of big tech companies including Amazon and Google, as well as research organizations are coming up with ways to make them more useful. What will it take to create voice assistants that work for everyone right out of the...

One of AI’s biggest, unsolved problems is what the advanced algorithms should do when they confront a situation they don’t have an answer for. For programs like Chat GPT, that could mean providing a confidently wrong answer, what’s often called a “hallucination”; for others, as with self-driving cars, there could be much more serious consequences. But what if AIs could be taught to recognize what they don’t understand and adjust accordingly? Usama Fayyad, the executive director for the...

Sail-powered cargo ships are making waves on the seas. High-tech versions of old tools are being installed on existing cargo ships in order to reduce fuel costs and help decarbonize the industry, which currently generates 3% of all human-created greenhouse gasses. Retrofitting cargo ships with sails could make maritime shipping greener and cheaper, and even change how the complicated shipping industry works. WSJ host Danny Lewis reports. What do you think about the show? Let us know on...

Breast milk imparts a number of long-term health benefits to babies, including a lower risk of asthma, obesity, Type 1 diabetes and sudden infant death syndrome (SIDS), according to the Centers for Disease Control and Prevention. But for a variety of reasons, many parents turn to formula. Now, several startups such as BIOMILQ and Helaina are working on new kinds of infant nutrition products that promise to better mimic parts of human breast milk—and may lead to advances in adult nutrition...

The next generation of nuclear power plants could be tiny, and that could mean big things for carbon-free electricity. Several companies including NuScale Power and Bill Gates’ TerraPower are developing small modular reactors that promise to be more adaptable than the towering conventional nuclear power plants. After years of development and growing investment, the first of these next-generation reactors could go online by 2030. But will their promises to provide safe and plentiful energy...

There may come a day when everyone will be wearing hearing aids. That’s because today’s hearing aids can do much more than clarify and amplify sound. Companies like Starkey are adding features like cognitive activity tracking and exercise monitoring. They’re developing tech that aims to warn users before they might fall and predict aspects of mental health too. If barriers like high cost and social stigma are addressed, hearing aids could become a vital accessory, whether or not you’re one of...

What if there were a way to generate clean solar electricity from space and send it directly to Earth? It sounds like science-fiction, but Caltech engineers are working on ways to collect solar energy on orbiting satellites and wirelessly beam that power back to stations on the ground. The results of their experiments suggest that space-based solar power may have a bright future. But while they’ve been able to show it’s possible on a demonstration satellite, getting power from orbit to Earth...
