Orbiting satellites are mostly propelled by gravity. But electrospray propulsion is sometimes used to reposition them. The fine nozzles in such systems are notoriously prone to breakage though, so researchers developed a way to create them out of their own fuel source, making them self-healing.

When oxygen interacts with uranium, an oxidation reaction occurs that, when mixed with other elements, can create secondary minerals much like rust forms on metal. Three such minerals never before spotted have been found in the Red Canyon region of Utah growing on the walls of old uranium mines.

Following the lead of Tokyo police last month, a team of mechanical engineers has devised a retrieval system that captures small drones and carries them unharmed to desired location. ​​

Syringe pumps can cost hundreds or even thousands of dollars. But researchers from Michigan Technological University have now created an open-source library of 3D-printable designs, enabling anyone in need of the commonly used scientific tool to produce their own at a fraction of the cost.

While current communications platforms offer up plenty of content for our eyes and ears, some feel that our noses are missing out on all the fun and have developed the oPhone, a Bluetooth-enabled odor emitting device designed to enable users to send smells to one another as a text or email.

The 3D printing revolution could be set to enter a new phase with a team from Michigan Technical University building a metal 3D printer for under $1,500. The team has made everything required to build the printer, including detailed plans, software and firmware, freely available.
