From Amazon to the US Army, everybody wants one (or 150).

A team of scientists hopes deep-earth lithium could sustain America's vast demand for batteries. But extracting it won't be easy.

Deep learning AI has accurately created color images from night vision images.

“I thought, why not direct these high-power beams, instead of into fusion plasma, down into rock and vaporize the hole?”

Aptera expects to begin delivering its solar-powered car later in 2022.

For the very first time, an AR contact lens was worn on the eye of a human subject. And it has about 30 times the pixel density of an iPhone.

Anxieties about being identified will be superseded by fears of being analyzed.

The airships have a range of 4,000 nautical miles, can fly for five days, and can cruise as high as 20,000 feet at 80 mph. They take to the skies over Spain in 2026.

An out-of-this-world idea could help reduce some of the risk of solar geoengineering.

Photosynthesis is powerful but very inefficient. Humans can improve on this biochemical process to help the planet.

Experts believe they could cut the time it takes a rocket to reach Mars by up to 25%, shaving about two months off the trip.

A "bio-battery" made from genetically engineered bacteria could store excess renewable energy and release it as needed.

AI systems can carry on convincing conversations, but they have no understanding of what they're saying. Humans are easily fooled.

Technology will not save the world, and it is inherently neither good nor bad. But, when tech is coupled to human virtue, good will prevail.

Preventing scurvy is not just a problem in the Antarctic.

The strangest thing about trying to predict the future is that our only clues lie in the past.

It could make enough drinking water for a family of four.

No ouija board required.

It has no moving parts and could allow us to tap into renewable energy year round.

In a major advance, scientists have found a new and groundbreaking way to force electrons to flow only in one direction in a superconductor.

The Hyperloop is physically possible, but engineering challenges will make its construction very difficult. Also, accidents would be catastrophic.

Now they're pointing the way to future battery technologies.

But does Amazon know when you're tired or hungry?

AR promises us a magical world.

Capturing energy from clubbers could help power homes and buildings.

Meet the power plant of the future.

A team of scientists has warned that marketers seek to advertise in our dreams. Will our sleep be commercialized against our wishes?

Today, we could use Big Data to radically reform democracy. Tomorrow, we could build nanofabricators and usher in an era of abundance. Is society ready?

Nanofabricators could quickly synthesize whatever we need, molecule by molecule.

The metaverse may leave us perpetually unsure whether the people we encounter are authentic or high-quality fakes.
