3D printers are common today, and they can produce shape and color reasonably well. While shape and color are two of an object's three most noticeable visual features, the other is gloss. Current 3D printers don't do well with changing the glossiness of the surface. MIT says glossiness is difficult because 3D printing hardware is designed to deal with different viscosities of varnishes required to give a surface a glossy or matte look.

There are several ways to figure out which robot design is the most efficient for crossing various terrains. The most time-consuming would be to simply build every variation of a robot and test them in the real world. MIT has developed a system called RoboGrammar that can test various robot designs virtually and determine which is the best for crossing particular types of terrain.

Deep learning neural networks are artificial intelligence systems that are being used for increasingly important decisions. Deep learning neural networks are used for tasks as varied as autonomous driving to diagnosing medical conditions. This type of network excels at recognizing patterns in large and complex datasets to help with decision-making.

MIT researchers have developed a new material inspired by camel fur made from two layers that can keep perishable goods cool without needing any power. The two-layer passive cooling system is made of hydrogel and aerogel. Researchers say that it can be used to keep foods or pharmaceutical cool for days without needing electricity.

Tracking drones or whales under the ocean is very difficult because GPS signals break down rapidly in seawater. Typically tracking objects underwater is done using acoustic signaling, but tracking devices using that technique typically require batteries, making them short-lived. MIT has a new solution that might make it easier to conduct ocean explorations and track sea creatures dubbed Underwater Backscatter Localization or UBL.

MIT has invented a tool that uses artificial intelligence to identify those with asymptomatic COVID-19 infections. Asymptomatic people are the most difficult to detect and can spread the infection without knowing that they have it. Since they are asymptomatic, they are unlikely to seek testing and continue their daily routine unknowingly infecting others.

3D printers are exact and are a fantastic way to print complicated parts that couldn't be built otherwise. However, sometimes 3D printers make mistakes by extruding too much material, too little, or putting material in the wrong spot. Researchers at MIT have harnessed a common 3D printer defect to create a new textile called DefeXtiles.

MIT has been working on small autonomous boats for the last five years and has recently made some significant changes. The autonomous boats, called Roboat, are now two meters long and are capable of carrying passengers. The latest version is called Roboat II, and it also has a new algorithm called Simultaneous Localization and Mapping or SLAM.

Researchers at MIT have created a new system that uses machine learning to help linguists decipher languages that have been lost to time. Research suggests that most languages that have ever existed are no longer spoken, with dozens of dead languages considered to be undeciphered. Linguists don't know enough about the grammar, vocabulary, and syntax to understand texts left behind in these lost languages.

Researchers at MIT have announced they have significantly boosted the output of a machine they created able to extract drinkable water directly from the air, even in dry regions. The device uses heat from the sun or another source in its process.

A new face mask prototype introduces a tantalizing alternative to the coveted N95 face mask, offering a reusable version made from silicone rubber that has the same level of effectiveness. The project comes from researchers with MIT and Brigham and Women's Hospital who explain that this mask can be made using the injection molding systems that are already available in a number of factories.

MIT created a surgical adhesive last year that was able to quickly and firmly stick to wet surfaces like biological tissues. The double-sided adhesive tape was shown to be usable to seal rips and tears in lungs and intestines in seconds. MIT scientists have further developed that adhesive so that it can detach from the underlying tissue without causing any damage.
