The light rail network in the Salt Lake City area already does a lot to improve air quality. Its three lines move more than 67,000 people a day along 45 miles of track, saving countless car trips and sparing the air tons upon tons of petroleum-powered pollutants.

Many modern technological applications are based on magnetic forces. Examples are moving components in electric vehicles and storing data on hard disks. Magnetic fields are also used as sensors to detect other magnetic fields. In the automotive industry, for example, more precise...

Using multiple autonomous vehicles simultaneously, an interdisciplinary team of scientists and engineers returns to the U.S. after exploring the North Pacific Subtropical front – a sharp boundary where cold fresh waters from the north meet warm salty waters from the south. The...

Connected cruise control uses vehicle-to-vehicle communication to let automated vehicles respond to multiple cars at a time in an effort to save energy and improve safety. University of Michigan researchers have demonstrated its effectiveness on public roads, even when just one automated...

Before launching their latest science experiment, University at Buffalo researchers bought more than 200 types of tea, chocolate, herbs, and other foodstuffs. The goal wasn't to stock up for long hours in the lab but to find an elusive, edible contrast agent to show doctors what's happening...

MIT researchers, working with scientists from Brigham and Women's Hospital, have developed a new way to power and communicate with devices implanted deep within the human body. Such devices could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the...

Researchers at MIT's Little Devices Lab have developed a set of modular blocks that can be put together in different ways to produce diagnostic devices. These "plug-and-play" devices, which require little expertise to assemble, can test blood glucose levels in diabetic patients or detect viral infection, among...

After a patient has a heart attack, a cascade of events leading to heart failure begins. Damage to the area in the heart where a blood vessel was blocked leads to scar tissue. In response to scarring, the heart will remodel to compensate. This process often ends in ventricular or valve...

Medical devices powered by synthetic proteins created from repeated sequences of proteins may be possible, according to materials science and biotechnology experts, who looked at material inspired by the proteins in squid ring teeth.
