Researchers have developed a new “high-entropy” metal alloy that has a higher strength-to-weight ratio than any other existing metal material. High-entropy alloys are materials that consist of five or more metals in approximately equal amounts.
Engineers at the University of California, San Diego have demonstrated a new and more efficient way to trap light, using a phenomenon called bound states in the continuum (BIC) that was first proposed in the early days of quantum wave mechanics.
The discovery of a new form of ice could lead to an improved understanding of our planet’s geology, potentially helping to unlock new solutions in the production, transportation and storage of energy. Ice XVI, the least dense of all known forms of ice, has a highly symmetric cage-like structure that can trap gaseous molecules to form compounds known as clathrates or gas hydrates.
Using a gene-editing system originally developed to delete specific genes, MIT researchers have now shown that they can reliably turn on any gene of their choosing in living cells.
Future fitness trackers could soon add blood-oxygen levels to the list of vital signs measured with new technology developed by engineers.
For the first time, scientists report the development of a stretchable “electronic skin” closely modeled after our own that can detect not just pressure, but also what direction it’s coming from.
The empty spacesuit that sat on the operating table in a lab at Houston Methodist Hospital's research institute made for an unusual patient.
Malaria parasites invade human red blood cells, which they bring to burst and infect others. Researchers at the University of Basel and the Swiss Tropical and Public Health Institute called nano imitations of host cell membranes have developed that deceive and trick the pathogen. This could lead to novel therapeutic and vaccine strategies against malaria and other infectious diseases.
As part of a project demonstrating new 3-D printing techniques, Princeton researchers have embedded tiny light-emitting diodes into a standard contact lens, allowing the device to project beams of colored light. The lens is not designed for actual use, though. Instead, the team created the device to demonstrate the ability to 3-D print electronics into complex shapes and materials.
Researchers at Rice University have created flexible, patterned sheets of multilayer graphene from a cheap polymer by burning it with a computer-controlled laser. The process works in air at room temperature and eliminates the need for hot furnaces and controlled environments, and it makes graphene that may be suitable for electronics or energy storage.
Precious elements such as platinum work well as catalysts in chemical reactions, but require large amounts of metal and can be expensive. However, computational modeling below the nanoscale level may allow researchers to design more efficient and affordable catalysts from gold.
Off the West Coast of the United States, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming enough to cause these carbon deposits to melt, releasing methane into the sediments and surrounding water.
Hydrogen could be an important source of clean energy, and the cleanest way to produce hydrogen gas is to split water into hydrogen and oxygen. But the catalyst currently used to facilitate this water-splitting reaction is platinum. And that’s a problem.
It may be possible to develop a simple blood test that, by detecting changes in the zinc in our bodies, could help to diagnose breast cancer early.
Scientists have shown how advanced computer simulations can be used to design new composite materials. Nanocomposites, which are widely used in industry, are revolutionary materials in which microscopic particles are dispersed through plastics.
