New Gene Therapy Technique May Help Prevent Cancer Metastasis

MIT researchers have developed a new gene therapy technique that uses microRNAs — small noncoding RNA molecules that regulate gene expression — to control breast cancer metastasis. The spread of malignant cells around the body, known as metastasis, is the leading cause of mortality in women with breast cancer. Now, a new gene therapy technique […]

MIT Scientists Help Reduce Runoff Pollution

Researchers from MIT have found a way to make pesticides stick to leaves instead of bouncing off, helping to reduce runoff pollution. When farmers spray their fields with pesticides or other treatments, only 2 percent of the spray sticks to the plants. A significant portion of it typically bounces right off the plants, lands on […]

Carbon Nanotube Stitches

Using carbon nanotube “stitches,” aerospace engineers from MIT have found a way to strengthen composites, helping make airplane frames lighter and more damage-resistant. The newest Airbus and Boeing passenger jets flying today are made primarily from advanced composite materials such as carbon fiber reinforced plastic — extremely light, durable materials that reduce the overall weight […]

New Device Delivers Therapy to Tumor Sites

A newly published study from MIT describes an adhesive patch that can stick to the tumor site, either before or after surgery, to deliver a triple-combination of drug, gene, and photo (light-based) therapy. Approximately one in 20 people will develop colorectal cancer in their lifetime, making it the third-most prevalent form of the disease in […]

New Battery Could Overcome Key Drawbacks of Lithium-Air Batteries

Engineers from MIT propose that a new lithium-oxygen battery material could be packaged in batteries that are very similar to conventional sealed batteries yet provide much more energy for their weight. Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output […]

MIT Study Opens New Realms of Light-Matter Interaction

A new study from MIT shows that some “forbidden” light emissions are in fact possible, and could enable new sensors and light-emitting devices. A new MIT study could open up new areas of technology based on types of light emission that had been thought to be “forbidden,” or at least so unlikely as to be […]

Yale Engineers Charging Toward Better Lithium Oxygen Batteries

Yale researchers have devised a method that brings marketable Li-O2 batteries closer to reality, improving both the batteries’ performance and the ability to study them. In recent years, lithium-oxygen batteries have intrigued researchers with their potential. They can store at least two to three times the energy as lithium-ion batteries can, which are the current standard […]

Researchers Turn Wasted Heat Into Power

Yale University engineers have developed a new technology that makes energy from the low-temperature wasted heat produced by industrial sources and power plants. It is estimated that recoverable waste heat in the U.S. alone could power tens of millions of homes. Although existing technologies can reuse high-temperature heat or convert it to electricity, it is […]

MIT Develops Tough Hydrogel Hybrid

MIT engineers have developed a method to bind gelatin-like polymer materials called hydrogels and elastomers, which could be used to make artificial skin and longer-lasting contact lenses. If you leave a cube of Jell-O on the kitchen counter, eventually its water will evaporate, leaving behind a shrunken, hardened mass — hardly an appetizing confection. The […]

A New Way to Turn Electricity Into Light

By slowing down light to a speed slower than flowing electrons, scientists have developed a new way to turn electricity into light. When an airplane begins to move faster than the speed of sound, it creates a shockwave that produces a well-known “boom” of sound. Now, researchers at MIT and elsewhere have discovered a similar […]

MIT Engineers Search for a New Formula for Concrete

Engineers from MIT are seeking to redesign concrete by using bones and shells as blueprints for a stronger, more durable concrete. In a paper published online in the journal Construction and Building Materials, the team contrasts cement paste — concrete’s binding ingredient — with the structure and properties of natural materials such as bones, shells, […]

MIT Develops New Nanoparticle Catalysts

Using an atomically-thin coating of noble metal over a tiny particle made of a much more abundant and inexpensive material, MIT engineers have developed new nanoparticle catalysts that could reduce need for precious metals. Materials that speed up a chemical reaction without getting consumed in the process, known as catalysts, lie at the heart of […]

Yale Develops a New Tool in the War Against Dust

Inspired by gecko feet, Yale researchers have developed a promising tool in the war on dust. Micrometric and sub-micrometric contaminant particles — what most of us call “dust” — can cause big problems for art conservators, the electronics industry, aerospace engineers, and others. These nanoparticles can prevent a cellphone from working or rob the vitality […]

Researchers Create Perfect Nanoscrolls

Using both low- and high-frequency ultrasonic techniques, scientists have fabricated nanoscrolls made from graphene oxide flakes. Water filters of the future may be made from billions of tiny, graphene-based nanoscrolls. Each scroll, made by rolling up a single, atom-thick layer of graphene, could be tailored to trap specific molecules and pollutants in its tightly wound […]

Designing Hydrogen-Resistant Zirconium Alloys

Researchers from MIT have developed a new approach to designing hydrogen-resistant zirconium alloys, which could be useful in nuclear reactors. High-tech metal alloys are widely used in important materials such as the cladding that protects the fuel inside a nuclear reactor. But even the best alloys degrade over time, victims of a reactor’s high temperatures, […]
