A new protein is helping researchers to see brain activity in real time as never before.

Researchers have invented a device that can plug into a smartphone and test people's blood for HIV or syphilis.

Building a quantum computer can sometimes yield unexpected benefits — like providing the right environment to demonstrate that Albert Einstein's theory of special relativity is, in fact, correct.

Quantum dot masers could help develop quantum computers and probe the mysteries of entanglement.

Computers have figured out how to win at chess, checkers and tic-tac-toe, and now, a computer program has conquered the game of poker.

A new kind of neuroprosthetic device is made of flexible, stretchable materials, which gives it an advantage over stiffer devices.

The bacteria that cause cholera grab genes from other organisms in a particularly predatory way: They spear neighboring cells with a poison-tipped spike.

An Ohio-based company thinks it has a better idea for how to deliver packages to future online shoppers: combine drones with fuel-efficient, "green" delivery trucks.

The aurora borealis can make for a spectacular night sky show, even sometimes visible from space. Here are eight amazing facts about the northern lights.

Nobody likes ingrown toenails, but clipping off the offending bit might only make it worse. Now, a look at the physics of nail growth reveals the best way to cut an ingrown nail.

A patch made of flexible electronics could be attached to a person's skin and reveal problems such as poor circulation or dehydration, new research suggests.

Continents move, but what got them going? A new computer model shows it was gravity. Whole continents flattened out under their own weight.

The group who founded the European Jewish community, called Ashkenazi Jews, was just 350 people strong some 600 to 800 years ago, meaning European Jews are all 30th cousins.

Shrödinger's cat is a thought experiment that has fascinated physicists for decades. An experiment explores its ramifications with surprising results.

Researchers claim they've made artificial diamonds that are harder than any tested before; however, some dispute the claim.

A new app uses a phone's built-in 3D camera to detect obstacles, and then produces a vibration or tone to alert the user.

Electrons have split personalities depending on how many of them are around, suggests new research that may solve a physics mystery about electrical currents in superconductors.

People with injuries that destroyed part of a muscle could be helped with an experimental treatment that uses a pig bladder as a muscle scaffold, researchers say.
