Ammonia has enormous potential as a fuel of the future, but most current production methods make it a dirty source of energy. Yet a new method from MIT that would derive the compound using the Earth's rocks and natural heat cleans it up considerably.

Imagine having a picture on your wall that completely changes when the room gets too warm. Engineers at MIT have created a new printing technology called Thermochromorph to make full-color images that switch in response to temperature.

In order for a VR environment to seem real, it definitely helps if you can experience the sensation of touch within that virtual world. A special sleeve could soon allow people to better do so, using air instead of electric motors.

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.
