Scientists have already figured out how to grow meat in a lab, nurturing animal cells to multiply into chicken cutlets and burger patties. Now, MIT researchers are hoping to do the same with wood, to quickly produce in a lab what would take decades to grow in nature. From there, they could even coax wood tissue to grow into fully-formed shapes like, say, a table in order to mitigate the environmental harm of the logging and construction industries

In a paper recently published the
Journal of Cleaner Production, the researchers detail how they grew wood-like plant tissue from cells extracted from the leaves of a zinnia plant, without soil or sunlight. “The plant cells are similar to stem cells,” says Luis Fernando Velásquez-García, a principal scientist in MIT’s Microsystems Technology Laboratories and co-author of the paper. “They have the potential to be many things.”

A 3D-printed thruster that emits a stream of pure ions could be a low-cost, extremely efficient propulsion source for miniature satellites.
The nanosatellite thruster created by MIT researchers is the first of its kind to be entirely additively manufactured, using a combination of 3D printing and hydrothermal growth of zinc oxide nanowires. It is also the first thruster of this type to produce pure ions from the ionic liquids used to generate propulsion.

Technology News: Discovery suggests new promise for nonsilicon computer transistors
Once deemed suitable only for high-speed communication systems, an alloy called InGaAs might one day rival silicon in high-performance computing
10 Dec 2020
For decades, one material has so dominated the production of computer chips and transistors that the tech capital of the world Silicon Valley bears its name. But silicon’s reign may not last forever.
MIT researchers have found that an alloy called InGaAs (indium gallium arsenide) could hold the potential for smaller and more energy efficient transistors. Previously, researchers thought that the performance of InGaAs transistors deteriorated at small scales. But the new study shows this apparent deterioration is not an intrinsic property of the material itself.
