In a major step toward making a quantum computer using everyday materials, a team led by researchers at Princeton University has constructed a key piece of silicon hardware capable of controlling quantum behavior between two electrons with extremely high precision. The study was published Dec. 7 in the journal Science.
A team at Caltech has figured out a way to encode more than one holographic image in a single surface without any loss of resolution. The engineering feat overturns a long-held assumption that a single surface could only project a single image regardless of the angle of illumination.
The technology hinges on the ability of a carefully engineered surface to reflect light differently depending on the angle at which incoming light strikes that surface.
A new technique by which to 3D print metals, involving a widely used stainless steel, has been show to achieve exception levels of both strength and ductility, when compared to counterparts from more conventional processes.
The findings, published in Materials Today, outline how a joint research team from the University of Birmingham, UK, Stockholm University, Sweden and Zhejiang University, China were able to optimizing the process parameters during 3D printing to achieve the results.
Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells. To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules, particularly water, that have an affinity for the charged atoms.
A research team in the Department of Electrical and Electronic Information Engineering and the Electronics-Inspired Interdisciplinary Research Institute (EIIRIS) at Toyohashi University of Technology has developed an ultrastretchable bioprobe using Kirigami designs. The Kirigami-based bioprobe enables one to follow the shape of spherical and large deformable biological samples such as heart and brain tissues. In addition, its low strain-force characteristic reduces the force induced on organs, thereby enabling minimally invasive biological signal recording.
Jena (Germany) Whatever the size of mobile phones or computers are, the way in which such electronic devices operate relies on the interaction between various materials. For this reason, engineers as well as researchers need to know exactly how specific chemical elements inside a computer chip or a transistor diode behave, and what happens when these elements bond.
CAMBRIDGE, MA -- MIT researchers have discovered a way to make bacteria more vulnerable to a class of antibiotics known as quinolones, which include ciprofloxacin and are often used to treat infections such as Escherichia coli and Staphylococcus aureus.
A quantum information scientist from the National University of Singapore (NUS) has developed efficient "toolboxes" comprising theoretical tools and protocols for quantifying the security of high-speed quantum communication. Assistant Professor Charles Lim is part of an international team of experimental and theoretical scientists from Duke University, Ohio State University and Oak Ridge National Laboratory that has recently achieved a significant breakthrough in high-rate quantum secure communication.
Scientists at Tokyo Tech have made an important discovery concerning the development of layer-specific axonal connections in the developing visual system of Drosophila flies. This discovery provides valuable insights into how neurons in the developing brain are wired. The molecular mechanisms we found can serve as a universal principle for wiring axons also in higher animals. We assume our findings help stabilize the regenerating axons to the desired depth in the brain layers, in the case such as neuronal transplantation after injury.
Dec. 5, 2017--Children between the ages of 7 and 9 may be at greater risk for developing asthma if they consumed high amounts of fructose in early childhood or their mothers drank a lot of sugar-sweetened beverages while pregnant, according to new research published online in the Annals of the American Thoracic Society.
