For expecting parents, 24 weeks is an important milestone. It’s a little more than halfway through pregnancy, and it’s at this age that the fetus has at least a fighting chance of surviving outside its mother’s body. The odds of survival aren’t great—only about half of babies birthed at this age survive—but it’s possible.

This past summer, a plane went into a stomach-churning ascent and plunge 30,000 feet over the Gulf of Mexico. The goal was not thrill-seeking, but something more genuinely daring: for about 25 seconds at a time, the parabolic flight lifted the occupants into a state of simulated weightlessness, allowing a high-tech printer to spit out cardiac stem cells […]
Who are today’s up-and-coming entrepreneurs? That answer is very different than it was 20 years ago. Most new entrepreneurs are still white and male, but the U.S. entrepreneurial population is becoming much more diverse in terms of age, race and region. Cities in the southern half of the U.S., such as Los Angeles, Miami and Austin, […]
Wi-Fi can pass through walls. This fact is easy to take for granted, yet it’s the reason we can surf the web using a wireless router located in another room. But not all of that microwave radiation makes it to (or from) our phones, tablets, and laptops. Routers scatter and bounce their signal off objects, illuminating […]
Food and transportation aren’t the only aspects of a mission to Mars scientists must consider. Limited cargo space means to obtain tools or similar items, astronauts may need to make use of resources available on the red planet – like dirt. Four Northwestern University researchers were recently able to utilize a Martian dust simulant to […]
If you’re frustrated with slow wi-fi, you might be one of the many people eagerly awaiting the commercialisation of li-fi (or light-based wi-fi), which promises to be up to 100 times faster than the connections we use today. Most li-fi systems rely on transmitting data via LED bulbs, which means there are some limitations to how easily the technology […]
Hydrogels have shown significant potential in everything from wound dressings to soft robots, but their applications have been limited from their lack of toughness – until now. A team of scientists at Hokkaido University have developed a new set of hydrogel composites or “fiber-reinforced soft composites” that combine hydrogels with woven fiber fabric to create […]
It’s not every day that scientists are able to create an entirely new substance, but Harvard researchers managed to do just that, and in the process created what could be a world-changing material with a bunch of different applications. It’s called atomic metallic hydrogen, and it’s exactly what it sounds like: hydrogen in the form of metal. […]
It’s official: graphene has been made into a superconductor in its natural state – which means electrical current can flow through it with zero resistance. Last year, physicists managed to do this by doping graphene with calcium atoms, but this is the first time researchers have achieved superconductivity in the material without having to alter it. […]
Three-dimensional printers have brought major advances to every corner of manufacturing: Scientists have used the process to engineer human tissue, print a rubber material to make drones less dangerous to people on the ground, and create a lightweight material that’s 10 times stronger than steel and just 1/20th its density.
