MIT researchers have developed a chip that leverages sub-terahertz wavelengths for object recognition, which could be combined with light-based image sensors to help steer driverless cars through fog. Image courtesy of the researchers

Giving keener electric eyesight to autonomous vehicles

Autonomous vehicles largely depend on light-based image sensors to see through blind conditions. But those sensors often struggle in some conditions like heavy rain,...
Researchers mapped out pathways of energy flow that connect the high energy side of the absorbed solar spectrum to the low energy side. Image courtesy of the researchers

How green plants expand their capacity to use solar energy?

Green plants catch light that traverses the obvious sun based range and keeping in mind that a wide otherworldly range is required for adequate...

Observing hydrogen’s effects in metal

Hydrogen is the second smallest of all the atoms available. It has the property to penetrate directly into the crystal structure of the solid...
A new MIT study finds that over the coming decades climate change will affect the ocean’s color, intensifying its blue regions and its green ones.

Much of the surface ocean will shift in color by end of 21st century

The Earth's climate has changed throughout history. Just in the last 650,000 years, there have been seven cycles of glacial advance and retreat, with...
Researchers from MIT and elsewhere have designed the first fully flexible, battery-free “rectenna” — a device that converts energy from Wi-Fi signals into electricity — that could be used to power flexible and wearable electronics, medical devices, and sensors for the “internet of things.” Image: Christine Daniloff

Converting Wi-Fi signals to electricity with new 2-D materials

MIT scientists have taken a step forward with a device that can potentially convert energy from Wi-Fi signals into electricity. Usually, rectennas are used to...
MIT researchers have developed a new secure cryptocurrency that reduces data users need to join the network and verify transactions by up to 99 percent, compared to today’s popular cryptocurrencies, which could mean a more scalable network.

A faster, more efficient cryptocurrency

MIT scientists have devised a new cryptocurrency that definitely diminishes the data users need to join the system and confirm trasactions— by up to 99...

Mechanism helps explain the ear’s exquisite sensitivity

The human ear, similar to those of different mammals, is so uncommonly delicate that it can detect sound-wave-induced vibrations of the eardrum that move...
A microfluidic technique quickly sorts bacteria based on their capability to generate electricity.

Scientists find a technique to identify electricity-producing bacteria

MIT scientists have developed a new microfluidic method that allows microbes to be used as fuel and purify sewage water. The aim was to...
This artist's impression shows hot gas orbiting in a disk around a rapidly-spinning black hole. The elongated spot depicts an X-ray-bright region in the disk, which allows the spin of the black hole to be estimated. Image: NASA/CXC/M. Weiss

X-ray pulse detected near event horizon as black hole devours star

On Nov. 22, 2014, stargazers detected an uncommon vent in the night sky: A supermassive black hole at the center of a galaxy, almost...
