Balloons that trick the stomach into feeling full have long been used for weight loss. But, they become less effective the longer they stay inflated. Engineers have devised a balloon that inflates and deflates on demand – it reduced food intake by 60%.

Although brain-implanted electrodes do reduce the effects of neurological disorders, implanting and activating those electrodes is a tricky process. That's why scientists are now developing an alternative, in the form of injectable magnetic discs.

Researchers at MIT have unexpectedly stumbled upon a way to 3D print active electronics – meaning transistors and components for controlling electrical signals – without the use of semiconductors or even special fabrication technology.

Ordinarily, the 3D printing of multi-colored objects is a relatively complex and inefficient process. That could soon change, however, thanks to a clever new technique in which a temperature-sensitive print media gets "ironed" after being extruded.

Using a 3D printer that works with molten glass, researchers forged LEGO-like glass bricks with a strength comparable to concrete. The bricks could have a role in circular construction in which materials are used over and over again.

MIT scientists have coaxed atoms into an exotic “edge state” for the first time, allowing them to flow completely friction-free. The breakthrough could lead to better superconductor materials.

A new study from MIT has revealed the exact mechanism by which fasting causes intestinal stem cells to regenerate, which is one of the practice's benefits. However, the study also showed a downside that needs to be considered when breaking a fast.

When someone overdoses on opioids, it's critically important that they receive a dose of the opioid-reversing drug naloxone as soon as possible – otherwise, death is a distinct possibility. That's where a new implant comes in, as it automatically dispenses naloxone from within the body.

MIT scientists have discovered an intriguing new way to produce hydrogen fuel, using just soda cans, seawater and coffee grounds. The team says the chemical reaction could power engines or fuel cells in marine vehicles that suck in seawater.

While cochlear implants do allow some deaf people to hear, they also incorporate potentially problematic external components located on the side of the head. That could soon change, however, thanks to an experimental new implantable microphone.

Researchers have figured out how a commonly used general anesthetic drug induces unconsciousness by causing brain activity to become increasingly unstable. The findings could lead to better anesthetic control in the operating room.

It’s ironic that while many regions struggle with water shortages, there’s heaps of the stuff floating around in the air everywhere. A new MIT water harvester design can pull enough fresh water out of the air to meet the daily needs of several people.
