Although small amounts of fluoride in drinking water may help to strengthen teeth and bones, too much can be dangerous. With that in mind, a simple new test has been designed to determine if fluoride levels are too high.

A new study from Northwestern University is demonstrating evidence a novel implantable ultrasound device allows a less toxic formulation of chemotherapy to cross the blood-brain barrier and destroy deadly tumors.

Although VR tech may allow users to see and hear computer-generated environments, the extent to which people can feel those worlds is still quite limited. That could be about to change, though, thanks to what's being called an "epidermal VR" system.

While it's now common to see 3D-printed prototypes, the use of 3D printers for manufacturing is still limited. That could be about to change, thanks to a new model that's being heralded as "the largest and highest throughput printer in its class."

A new study out of Northwestern University has found the old advice of solving a problem by "sleeping on it" is not only true, but can be improved by using sound cues to manipulate our brain while we sleep.

A team of researchers is developing a bioelectronic implant designed to sense an opioid overdose and immediately administer a dose of life-saving naloxone.

Scientists have developed a tiny new kind of bio-compatible laser that could, theoretically, be implanted inside living tissues without causing them damage.

Researchers have found evidence that Schomburgk’s deer – thought extinct since 1938 – may have lived until at least the 1990s, and possibly still today.

A new analytical tool suggests distinct microbiome changes caused by spaceflight are most likely caused by microgravity.

It’s not unusual to find rust around salt water, but now the pairing might be more useful. Researchers have found that electricity can be produced when salt water flows over the top of thin films of rust. The process was previously seen in – what else – graphene, but rust is far easier to scale up.

The LIGO detector uses 4-km-long (2.5-mi) arms. But now, a Northwestern University team is aiming to build a gravitational wave detector small enough to fit on a tabletop, which could detect signals the larger facilities miss.

The first polarized light from a gamma ray burst billions of light years away is helping astronomers gain a better understanding of collapsing stars and other high-energy phenomena. Originating in the constellation of Fornax, the light brighter than a billion suns came from massive jets of plasma.
