High-speed graphene transistors achieve world-record 300 GHz
UCLA researchers have fabricated the fastest graphene transistor to date, using a new fabrication process with a nanowire as a self-aligned gate.
Self-aligned gates are a key element in modern transistors, which are semiconductor devices used to amplify and switch electronic signals. Gates are used to switch the transistor between various states, and self-aligned gates were developed to [...]

Edible Nanostructures
Sugar, salt, alcohol and a little serendipity led a Northwestern University research team to discover a new class of nanostructures that could be used for gas storage and food and medical technologies. And the compounds are edible. The porous crystals are the first known all-natural metal-organic frameworks (MOFs) that are simple to make. Most other MOFs [...]

Caltech chemists develop simple technique to visualize atomic-scale structures
Researchers at the California Institute of Technology (Caltech) have devised a new technique — using a sheet of carbon just one atom thick — to visualize the structure of molecules.
The technique, which was used to obtain the first direct images of how water coats surfaces at room temperature, can also be used to image a [...]

Building large-scale quantum computers
Dr. Suzanne Gildert will speak on “Building large-scale quantum computers: Fundamentals, technology and applications” at Teleplace, September 4, 10 a.m. PST.
“The talk will explain why quantum computers are useful, and also dispel some of the myths about what they can and cannot do,” she says. “It will address some of the practical ways in which we can [...]

God did not create the universe: Stephen Hawking
God did not create the universe, says Stephen Hawking in a new book, The Grand Design, co-authored with U.S. physicist Leonard Mlodinow (to be released Sept. 7).
He said the 1992 discovery of a planet orbiting another star other than the Sun helped deconstruct the view of the father of physics Isaac Newton that the universe could not [...]

New evidence that fat cells are not just dormant storage depots for calories
Scientists are reporting new evidence that the fat tissue — far from being a dormant storage depot for surplus calories — is an active organ that sends chemical signals to other parts of the body, perhaps increasing the risk of heart attacks, cancer, and other diseases.
They are reporting discovery of 20 new hormones and other [...]

Supercomputing on a cell phone
Researchers in MIT’s Department of Mechanical Engineering have developed software that can simulate complicated physical phenomena — how cracks form in building materials, for instance, or fluids flow through irregular channels — on an ordinary smartphone.
Although the current version of the software is for demonstration purposes, the work could lead to applications that let engineers [...]

Personalized energy systems for heating, cooling, and powering cars
MIT researchers have developed a new concept of personalized energy systems, in which individual homes and small businesses produce their own energy for heating, cooling and powering cars.
“Our goal is to make each home its own power station,” said study leader Daniel Nocera, Ph.D of MIT. “We’re working toward development of ‘personalized’ energy units that [...]

Google’s Earth
“In Google, we are at once the surveilled and the individual retinal cells of the surveillant, however many millions of us, constantly if unconsciously participatory,” opines novelist William Gibson. ”We are part of a post-geographical, post-national super-state, one that handily says no to China. Or yes, depending on profit considerations and strategy. But we do not [...]

Silicon nanocrystals break miniaturization barrier for memory chips
Rice University scientists have created the first two-terminal memory chips that use only silicon to generate nanocrystal wires as small as 5 nanometers — far smaller than circuitry in even the most advanced computers and electronic devices. The technology breakthrough promises to extend the limits of miniaturization subject to Moore’s Law, and should be easily [...]
