artificial intelligenceIBM overcomes von Neumann bottleneck for AI hundreds of time faster using hundreds of times less energy

No Comments
IBM Research AI team demonstrated deep neural network (DNN) training with large arrays of analog memory devices at the same accuracy as a Graphical Processing Unit (GPU)-based system. This is a major step on the path to the kind of …

nuclearOn track to commercial extraction of uranium from seawater

No Comments
Researchers at Pacific Northwest National Laboratory and LCW Supercritical Technologies have created five grams of yellowcake — a powdered form of uranium used to produce fuel for nuclear power production — using acrylic fibers to extract it from seawater. LCW, …

astronomy121 giant exoplanets in habitable zones may have habitable moons

No Comments
Researchers have identified more than 100 giant planets that potentially host moons capable of supporting life. Their work will guide the design of future telescopes that can detect these potential moons and look for tell-tale signs of life, called biosignatures, …

energyPerovskite and silicon tandem solar could beat silicon solar in some to many situations

No Comments
Researchers from EPFL’s Photovoltaics Laboratory and the CSEM PV-center have developed an economically competitive solution to silicon solar cells. They have integrated a perovskite cell directly on top of a standard silicon-based cell, obtaining a record efficiency of 25.2 percent. …

astronomyCeres has 5-8 times more organic material than previously believed

No Comments
A new analysis of data from NASA’s Dawn mission suggests that organic matter may exist in surprisingly high concentrations on the dwarf planet’s surface. To get an initial idea of how abundant those compounds might be, the original research team …

communicationJapan’s next generation terahertz communication will push to 400 gigabits per second

No Comments
Nippon Telephone and Tokyo Institute of Technology have jointly developed an ultra high-speed IC for wireless front-end that operates on a terahertz frequency band, and in the 300 GHz band they have succeeded in developing the world’s fastest 100 gigabit …

astronomyColliding wormholes will have gravitational echoes which could be detectable

No Comments
The gravity waves that were detected might have been from the collision of wormholes. If there are gravitational echoes then the collision was from wormholes and not blackholes. There is a problem with black holes—they present an edge, called an …

materialsNew Class of 2D Artificial Materials Created

No Comments
Researchers created a new class of two-dimensional artificial materials with ferroelectric-like properties at room temperature that don’t exist in nature yet can conduct electricity. Above – This image shows the positions of atoms in a ferroelectric-like metal that contains barium …

DNAProgrammed DNA origami nanobot kills cancer in mice

No Comments
Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences, have successfully programmed nanorobots to shrink tumors by cutting off their blood supply. Above – Nanorobots …

batteriesVolkswagan, Google and D-Wave simulating chemical batteries on quantum computers

No Comments
Volkswagen experts will simulate the chemical structure of batteries on quantum computers. They have succeeded in simulating industrially relevant molecules using a quantum computer. This is important for the development of high-performance electric vehicle batteries. They simulated molecules like lithium-hydrogen …
