Water-based material could be used to make artificial skin, longer-lasting contact lenses. Watch Video If you leave a cube of Jell-O on the kitchen counter, eventually its water will evaporate, leaving behind a shrunken, hardened mass...

Summary: Turning Electricity Into Light, Using Graphene 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...
Semimetals

Better understanding of topological semimetals could help usher in future electronics. Discovered just five years ago, topological semimetals are materials with unusual physical properties that could make them useful for future electronics. In the latest issue...
Marijuana

With the world’s population expected to exceed nine billion by 2050, scientists are working to develop new ways to meet rising global demand for food, energy and water without increasing the strain on natural...
Nanotech

A team of MIT researchers has for the first time demonstrated a device based on a method that enables solar cells to break through a theoretically predicted ceiling on how much sunlight they can...

University of California, Irvine researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough work could...

Feedback technique used on diamond “qubits” could make quantum computing more practical.
nanotech

A new tool is emerging in the fight against antibiotic-resistant bacterial disease. Beyond the global efforts to limit overuse and abuse of antibiotic drugs, nanomedicine is finding additional ways to attack these superbugs. Nanoparticles, a...
terahertz

Engineers have devised a way to focus terahertz radiation using an array of stacked metal plates, a technique which may prove useful for terahertz imaging or in next-generation data networks. Terahertz radiation is a relatively...
semiconductors

Our modern world is based on semiconductors. In addition to your computer, cellphones, and digital cameras, semiconductors are a critical component of a growing number of devices. Think of the high-efficiency LED lights you...

CAMBRIDGE, Mass. -- Since the 1960s, computer chips have been built using a process called photolithography. But in the past five years, chip features have gotten smaller than the wavelength of light, which has required...

New techniques for building microelectromechanical systems show promise. CAMBRIDGE, Mass. -- Microelectromechanical systems — or MEMS — were a $12 billion business in 2014. But that market is dominated by just a handful of devices,...
