Tiny sensors are embedded into stretchable, integrated mesh that grows with the developing tissue, allowing scientists to track how cells grow into organs.

Researchers from Harvard University, NASA’s Jet Propulsion Lab, and the University of Edinburgh suggest that regions of the Martian surface could be made habitable with a material — silica aerogel — that would mimic Earth’s atmospheric greenhouse effect.

In a breakthrough on the road toward ultra-high-speed Wi-Fi, Harvard researchers have demonstrated for the first time a laser that can emit microwaves wirelessly, modulate them, and receive external radio frequency signals.

Researchers have created a micro-robot whose electroadhesive foot pads allow it to climb on vertical and upside-down conductive surfaces, such as the inside walls of a jet engine. Groups of micro-robots could one day be used to inspect complicated machinery and detect safety issues sooner, while reducing maintenance costs.

Harvard researchers have started to combine bacteria with semiconductor technology that, similar to solar panels on a roof, harvests energy from light and, when coupled to the microbes’ surface, boosts their biosynthetic potential.
