MIT scientists have managed to build neural networks that are both faster and cheaper to produce while using less energy.
New research outlines the materials and reactions that could have sparked life on Earth. It is the simplest hypothesis yet.
The risk of satellite collisions would be extremely high after a major solar storm, experts say.
The regional entity overseeing much of the electric power grid in the Midwest — the Midcontinent Independent System Operator (MISO) — approved a set of major new transmission system upgrades that will bring billions of dollars in benefits to the region while better enabling states and utilities to pursue transitions to clean energy.
See here for my colleague Sam Gomberg’s excellent post explaining the background and details on what is known as “Tranche 1” of MISO’s long range transmission planning process. This much-needed set of 18 projects will improve electricity reliability, address overloaded wires, and help unlock more lower-cost wind and solar power to replace costly, polluting fossil fuel plants in Michigan and many other states in the Midwest (including Illinois and Minnesota).
Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye… You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research by scientists from Inserm, CNRS and Université de Montpellier at the Structural Biology Center in Montpellier[1]. This highly innovative “nano-robot” should enable closer study of the mechanical forces applied at microscopic levels, which are crucial for many biological and pathological processes. It is described in a new study published in Nature Communications.
Our cells are subject to mechanical forces exerted on a microscopic scale, triggering biological signals essential to many cell processes involved in the normal functioning of our body or in the development of diseases.
For example, the feeling of touch is partly conditional on the application of mechanical forces on specific cell receptors (the discovery of which was this year rewarded by the Nobel Prize in Physiology or Medicine).
“This is a significant milestone in renewable technology production. From touch screen displays, biosensors, radio frequency identification tags, electric vehicle batteries, and more, the technology’s applications are vast,” said Stuart Jara, HydroGraph chief executive officer.
With growing possibilities for printed electronics every day, the need for conductive inks like graphene ink is on the rise. HydroGraph’s highly competitive cost and mass production method for high quality graphene opens up a wealth of opportunity for the practical applications of conductive ink patterns.
“Once the ink is made, it can then be deployed in regular inkjet printers to make small-scale, flexible electronics. This puts manufacturing capabilities into the reach of many, making it far more accessible,” said Dr. Chris Sorensen, HydroGraph vice president R&D.
