Generating first-ever controlled ultrafast radiation using a plasma

  • PDF
(Apr. 4, 2012) — To observe ultrarapid phenomena such as the motion of electrons within matter, researchers need sources capable of producing extremely fast and energetic light radiation. Although devices capable of emitting pulses with attosecond (10-18 seconds) precision already exist, many research teams are striving to stretch the boundaries of these pulses' duration and intensity.

A team headed by the Laboratoire d'Optique Appliquée (LOA, CNRS/ENSTA-Paristech/Ecole Polytechnique), in collaboration with the CEA and the Laboratoire pour l'Utilisation des Lasers Intenses (CNRS/CEA/Ecole Polytechnique/UPMC), has succeeded for the first time in accelerating and guiding electrons in a plasma in a reproducible manner, using...

Titanic disaster 'unlikely to happen again'

  • PDF
(Apr. 4, 2012) — A ship science expert, Professor Ajit Shenoi, says that a seafaring tragedy on the scale of the Titanic disaster is unlikely to happen again.

Professor Shenoi, who is the Director of the Southampton Marine and Maritime Institute at the University of Southampton, believes this is due to the many lessons that have been learned as a result of the tragedy 100 years ago.

"A detailed Board of Trade inquiry set up after the tragedy identified that the reasons...

Listening to the radio even in an electric vehicle

  • PDF
(Apr. 4, 2012) — To enable radio reception in electric vehicles, manufacturers must install filters and insulate cables, since electrical signals will otherwise interfere with music and speech transmissions. Now, using new calculation methods, researchers are paving the way for pure listening pleasure while also helping to lower the associated costs.

Listening to the radio is a favorite German pastime. Every day, more than 60 million people turn their radios on, especially...

First targeted nanomedicine to enter human clinical studies

  • PDF
(Apr. 4, 2012) — A team of scientists, engineers and physicians from Brigham and Women's Hospital (BWH), Dana-Farber Cancer Institute (DFCI), Harvard Medical School (HMS), Massachusetts Institute of Technology (MIT), BIND Biosciences, Translational Genomics Research Institute (TGen), Wayne State University Karmanos Cancer Institute, and Weill Cornell Medical College have found promising effects of a first-in-class targeted cancer drug called BIND-014 in treating solid...

Nanoscale magnetic media diagnostics by rippling spin waves

  • PDF
(Apr. 3, 2012) — Memory devices based on magnetism are one of the core technologies of the computing industry, and engineers are working to develop new forms of magnetic memory that are faster, smaller, and more energy efficient than today's flash and SDRAM memory. They now have a new tool developed by a team from the National Institute of Standards and Technology (NIST), the University of Maryland Nanocenter and the Royal Institute of Technology in Sweden -- a method to detect defects...

Advanced power-grid research finds low-cost, low-carbon future in Western U.S.

  • PDF
(Apr. 3, 2012) — The least expensive way for the Western U.S. to reduce greenhouse gas emissions enough to help prevent the worst consequences of global warming is to replace coal with renewable and other sources of energy that may include nuclear power, according to a new study by University of California, Berkeley, researchers.

The experts reached this conclusion using SWITCH, a highly detailed computer model of the electric power grid, to study generation, transmission and...

China's rapid economic growth means population is 'wealthier but unhappier’

  • PDF
(Apr. 3, 2012) — The average personal income in China has risen by five per cent a year since the mid 1990s. Yet according to Professor John Knight and Dr Sai Ding in their new book, this recent wealth does not equate with personal happiness. In China's Remarkable Economic Growth, they find that the happiness of the Chinese people has not risen as expected. When people were asked to rate their happiness or satisfaction with life, the average happiness score was found to have fallen over...

To boldly go where no glass has gone before: Glass made in absence of gravity

  • PDF
(Apr. 3, 2012) — QUT's first foray into space is bound to be a giant step for mankind. Dr Martin Castillo from Queensland University of Technology's (QUT) Science and Engineering Faculty, and researcher for the university's micro-gravity drop tower, has partnered with the United States Air Force to fund world-first research into the development of ZBLAN glass.

Dr Castillo said the special glass will be the first QUT project to be launched into space.

"True ZBLAN glass...

Quantum information motion control is now improved

  • PDF
(Apr. 3, 2012) — Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. Their paper is about to be published in The European Physical Journal B. This study, led by scientists from Zhejiang University, Hangzhou, China, and the Centre for Computational Science and Engineering at the National University of Singapore, could have implications for quantum computers due to improvements in the transport of...
