MIT engineers have uncovered the secret to the exceptional toughness of conch shells, and say the same principles can be used for body armor and helmets.
A new oxygen-deficient titanium dioxide prepared with Mg reduction method drastically improves the carbon dioxide conversion efficiency up to three times the efficiency of existing photocatalyst. It is expected to be applied for carbon dioxide resources and reduction technology.
Study takes step toward mass-producible quantum computers.
New license-free tools will allow researchers to estimate the size of DNA fragments for a fraction of the cost of currently available methods. The tools, called a DNA ladders, can gauge DNA fragments ranging from about 50 to 5,000 base pairs in length.
By developing a way to tune the color of individual pixels, researchers have eliminated the need for subpixels -- allowing a greater density of pixels and much higher resolution for video displays.
George Washington University researchers, published in the New England Journal of Medicine, find through looking at genetic data sets of presumed cancer-free women who carry BRCA 1/2 variants, the co-occurrence of a rare COMT genetic variant in some women. This research outlines a strategy for looking at large genetic data sets for clues as to why a genetic carrier may never develop the associated diseases.
At the IEEE Symposium on Security and Privacy this week, researchers from MIT's Computer Science and Artificial Intelligence Laboratory are presenting a new system that uses Bitcoin's security machinery to defend against online identity theft.
Nagoya University researchers studied the thermal and electrical properties of one-dimensional crystals composed of tantalum, silicon and tellurium for thermoelectric cooling at temperatures below 250 K (-23°C). The thermoelectric characteristics of these crystals were varied at temperatures ranging from the cryogenic level of 50 K up to room temperature by doping with molybdenum and antimony. The crystals' thermoelectric power factors greatly exceeded those of conventional materials around room temperature, indicating their suitability for low-temperature applications.
Since the global supply chain for additive manufacturing (AM)-- also called 3-D printing-- requires companies to share CAD files within the organization or with outside parties via email or cloud, intellectual-property thieves and malefactors have many opportunities to filch a manufacturer's design files to produce counterfeit parts. Researchers have discovered ways for manufacturers to turn the tables on thieves by deliberately embedding hidden flaws in CAD files to thwart intellectual property theft.
Two B-25 bombers associated with American servicemen missing in action from World War II were recently documented in the waters off Papua New Guinea by Project Recover -- a collaborative team of marine scientists, archaeologists and volunteers who have combined efforts to locate aircraft and associated MIAs from World War II.
