Researchers Control a Material with Voltage

New research details how a MIT-based team has made important strides in the concept of using an electrical signal to control a magnetic memory. A new way of switching the magnetic properties of a material using just a small applied voltage, developed by researchers at MIT and collaborators elsewhere, could signal the beginning of a […]

Quantum-Dot Technology Improves TV Color Gamut

New quantum-dot technology is set to make LCD TVs more colorful and energy-efficient, all while costing less than OLED displays and other color gamut boosting methods. If LCD TVs start getting much more colorful — and energy-efficient — in the next few years, it will probably be thanks to MIT spinout QD Vision, a pioneer […]

Engineered Bacteria Can Store Memories of Chemical Exposure

New research from MIT reveals that engineered E. coli can store long-term memories of chemical exposure and other events in their DNA. MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications […]

Study Finds That a Strong Magnetic Field Shaped the Early Solar System

New research reveals the first experimental evidence that our solar system’s protoplanetary disk was shaped by an intense magnetic field that drove a massive amount of gas into the sun within just a few million years. Infant planetary systems are usually nothing more than swirling disks of gas and dust. Over the course of a […]

MIT Reveals Missing Piece of the Climate Puzzle

In a newly published study, MIT researchers show that a canonical view of global warming tells only half the story and reveal the missing piece of the climate puzzle. In classrooms and everyday conversation, explanations of global warming hinge on the greenhouse gas effect. In short, climate depends on the balance between two different kinds […]

New Fabrication Process Makes Taller Wind Turbines More Feasible

MIT engineers have developed a new fabrication system that adapts a traditional pipe-making technology to make wind turbines on location, at wind farms, making taller towers more economically feasible. Wind turbines across the globe are being made taller to capture more energy from the stronger winds that blow at greater heights. But it’s not easy, […]

New Algorithm Can Help Determine How to Treat Patients

Researchers from MIT, Harvard Medical School and the Einstein Medical Center in Philadelphia have developed a new algorithm that can, with high accuracy, determine whether a patient is suffering from emphysema or heart failure based on the concentration of carbon dioxide in a patient’s exhalations. Paramedics respond to a 911 call to find an elderly […]

Special Coating Makes Batteries Safer

A new special coating developed by a team of researchers prevents electrical current from damaging the digestive tract after accidental battery ingestion. Every year, nearly 4,000 children go to emergency rooms after swallowing button batteries — the flat, round batteries that power toys, hearing aids, calculators, and many other devices. Ingesting these batteries has severe […]

New System Lets Programmers Identify Sections of Their Code That Can Tolerate a Little Error

Engineers from MIT have developed a new system that lets programmers identify sections of their code that can tolerate a little error, determining which program instructions to assign to unreliable hardware components to maximize energy savings while still meeting the programmers’ accuracy requirements. As transistors get smaller, they also grow less reliable. Increasing their operating […]

Power Conserving Chip May Increase Smartphone Battery Life

A new power-conserving chip developed by MIT spinout Eta Devices may increase smartphone battery life and save energy in cell towers. Stream video on your smartphone, or use its GPS for an hour or two, and you’ll probably see the battery drain significantly. As data rates climb and smartphones adopt more power-hungry features, battery life […]
