From an original transparent etching (far right), engineers produced a photograph in the dark (top left), then attempted to reconstruct the object using first a physics-based algorithm (top right), then a trained neural network (bottom left), before combining both the neural network with the physics-based algorithm to produce the clearest, most accurate reproduction (bottom right) of the original ...

Deep-learning technique reveals “invisible” objects in the dark

Method could illuminate features of biological tissues in low-exposure images.

In this experiment, the new steam-generating device was mounted over a basin of water, placed on a small table, and partially surrounded by a simple, transparent solar concentrator. The researchers measured the temperature of the steam produced over the course of the test day, Oct. 21, 2017.

Sun-soaking device turns water into superheated steam

High-temperature steam might be used in remote regions to cook, clean, or sterilize medical equipment.

MIT researchers propose a concept for a renewable storage system, pictured here, that would store solar and wind energy in the form of white-hot liquid silicon, stored in heavily insulated tanks.

“Sun in a box” would store renewable energy for the grid

Design for system that provides solar- or wind-generated power on demand should be cheaper than other leading options.

A new MIT plane is propelled via ionic wind. Batteries in the fuselage (tan compartment in front of plane) supply voltage to electrodes (blue/white horizontal lines) strung along the length of the plane, generating a wind of ions that propels the plane forward.

MIT engineers fly first-ever plane with no moving parts

The silent, lightweight aircraft doesn’t depend on fossil fuels.

An MIT study proposes that laser technology on Earth could emit a beacon strong enough to attract attention from as far as 20,000 light years away.

E.T., we’re home

Existing laser technology could be fashioned into Earth’s “porch light” to attract alien astronomers, study finds.

Once mercury is emitted from the smokestacks of coal-fired power plants, among other sources, the gas can drift through the atmosphere for up to a year before settling into lakes and oceans.

Study: Impact of mercury-controlling policies shrinks with every five-year delay

Toxin will accumulate in the environment, particularly in remote regions, as countries delay implementing emissions controls.
