In the future, tiny medical devices could swim through our bodies to diagnose diseases, but keeping track of them all can be tricky. A new invention out of Caltech might make that easier: a chip loaded with sensors that can ping its location in the body, thanks to MRI-inspired technology.​

Another year, another iPhone update purporting to "revolutionize" the smartphone game. The big new thing in this round of updates is the replacement of fingerprint access with a new facial recognition system. It's undoubtedly a high-tech addition, but is it anything more than a gimmick?

The US National Transportation Safety Board has completed its investigation into a fatal crash involving a semi-truck and a Tesla Model S utilizing automated driving systems. The reasons for the crash are complex, but the report highlights issues with self-driving vehicles that should be of concern.

Audi has whipped the covers off a new RS 4 Avant. Gone are the old V8 and dual-clutch gearbox, and in their place is a downsized turbo V6 and torque converter. Don't think the Audi has gone soft, though. The all-wheel drive RS 4 should still give BMW M3 and AMG C63 owners nightmares.

Every particle has an antiparticle, which has the opposite charge. But it’s long been theorized that there’s an exception to the rule, with certain particles that are actually their own antiparticles. Now, scientists have found the first strong evidence for what they dub the “angel particle.”

How does Nissan's hybrid model for the Rogue perform? We used it as a family hauler for a week to see if the fuel economy benefits stack up, and how it drives compared to the deadpan standard gasoline model.

The US Navy has officially welcomed the world's largest aircraft carrier into the fleet. The 110,000 ton USS Gerald R. Ford (CVN 78)​ was formally commissioned in a ceremony where President Donald Trump gave the principal address inaugurating the vessel into its half century of active service.

The SETI Institute, in partnership with French startup Unistellar, wants to up the game for amateur astronomers by marketing a computerized 4.5-in (11.4 cm) reflecting telescope called the "eVscope" that acts as a crowd-sourcing instrument.

​Olaf Diegel of ODD Guitars has created a microphone that a player of his Spider guitar might use. The Skeletor that came out of the SLS machine is a perfect stylistic match for the voice of heavy metal himself, Ozzy Osbourne, or equally suited to the king of voodoo rock, Screaming Jay Hawkins.​

In the Star Trek universe, Vulcans could form a mental bond with someone else, syncing up their brains to the point that the two basically shared one consciousness. Researchers in Spain have now shown that humans do something a bit similar – just by having a conversation.

Lockheed Martin is recycling a Space Shuttle cargo container to create a prototype deep space habitat for NASA. The full-scale experimental module will be used to test technologies to provide astronauts with a safe living space that can operate autonomously when there is no one on board.

Continental, which also has concepts designed to improve in-car audio and security, will be running a concept autonomous car around its Frankfurt facility to try and fine-tune the way driverless cars navigate the complex city environment.
