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 […]

New Approach Could Kill Tumor Cells in the Brain More Effectively

New research shows that delivering chemotherapy directly into the brain cavity may kill tumor cells in the brain more effectively and avoid side effects. Every year, about 100,000 Americans are diagnosed with brain tumors that have spread from elsewhere in the body. These tumors, known as metastases, are usually treated with surgery followed by chemotherapy, […]

New Technology Allows Microscopic Devices to Autonomously Find Their Way

Researchers from MIT have developed a new target-finding mechanism that allows microscopic devices to autonomously find their way to areas of a cell surface. Nature has developed a wide variety of methods for guiding particular cells, enzymes, and molecules to specific structures inside the body: White blood cells can find their way to the site […]

Electrodialysis Can Provide Cost Effective Treatment of Salty Well Water

A newly published study reveals how electrodialysis can provide cost-effective treatment of salty water from oil and gas wells. The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that’s much […]

MIT Circuit Design Simplifies Superconducting Circuits

MIT researchers present a new circuit design that could unlock the power of experimental superconducting computer chips and make simple superconducting devices much cheaper to manufacture. Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today’s chips, an attractive trait given the increasing […]

Assessing the Technical Feasibility of the Proposed Mars One Mission

A new independent assessment of the Mars One Mission from MIT engineers reveals that the project may have to take a step back, at least to reconsider the mission’s technical feasibility. In 2012, the “Mars One” project, led by a Dutch nonprofit, announced plans to establish the first human colony on the Red Planet by […]

New Research Shows Solid Nanoparticles Can Deform Like a Liquid

Using a combination of laboratory analysis and computer modeling, new research shows that nanoparticles keep their internal crystal structure while deforming like a liquid. A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal […]

Researchers Control Nanoparticles with Light and Magnets

A team of researchers has developed particles that can glow with color-coded light and be manipulated with magnets, improving the likelihood of tracking the position of the nanoparticles as they move within the body or inside a cell. A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, […]

New Mechanism of Photoconduction Could Lead to Next Generation Excitonic Devices

Physicists at MIT have discovered that shining light on a single layer of molybdenum disulfide (MoS2) can make the material less conductive. It’s a well-known phenomenon in electronics: Shining light on a semiconductor, such as the silicon used in computer chips and solar cells, will make it more conductive. But now researchers have discovered that […]

MIT Engineers Develop New Approach to Boosting Biofuel Production

By simply altering the composition of the medium in which the yeast are grown, engineers at the Whitehead Institute for Biomedical Research and MIT were able to boost yeast’s ethanol production by about 80 percent. Yeast are commonly used to transform corn and other plant materials into biofuels such as ethanol. However, large concentrations of […]

New Technology Enables Fast and Cheap Nanomanufacturing

A newly published study from MIT details how arrays of tiny conical tips that eject ionized materials could fabricate nanoscale devices cheaply. Luis Fernando Velásquez-García’s group at MIT’s Microsystems Technology Laboratories (MTL) develops dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions. The technology has a range of promising applications: […]
