Where Science gets done

November 12, 2010

(Reuters) – The United States still leads the world with its scientific clout, armed with highly respected universities and a big war chest of funding, but Europe and Asia are catching up, according to a Thomson Reuters report released on Friday.

But U.S. influence is waning — not because the United States is doing less, but because other countries are doing more, Thomson’s Jonathan Adams and David Pendlebury found. “In 1981, U.S. scientists fielded nearly 40 percent of research papers in the most influential journals,” they wrote.

“By 2009, that figure was down to 29 percent. During the same period, European nations increased their share of research papers from 33 percent to 36 percent, while research contributed by nations in the Asia-Pacific region increased from 13 percent to 31 percent.” China is now the second-largest producer of scientific papers, after the United States, with nearly 11 percent of the world’s total. In 2008, Asian nations as a group passed the United States with $387 billion in research and development spending, compared with $384 billion in the United States and $280 billion in Europe.

Precisely half of U.S. research focuses on the biological sciences “just at the time when Asian nations are focusing on and investing substantial sums in engineering, physical sciences, and technology,” the report notes. In the United States, the Massachusetts Institute of Technology and California Institute of Technology (MIT and Caltech) led in research, the report found. Outside the United States, the Chinese Academy of Sciences and the Russian Academy of Sciences lead.

Earlier this week the United Nations Educational, Scientific and Cultural Organization, or UNESCO, released a report showing similar findings. UNESCO said in 2002, almost 83 percent of research and development was carried out in developed countries but this dropped to 76 percent by 2007. It found China was leading the pack of emerging nations with 1.4 million researchers.

This will be a significant step forward but if only I could also charge my laptop wirelessly as well………

From Asahi News:

Kawasaki, Japan, September 13, 2010 — Fujitsu Laboratories Limited today announced the development of wireless recharging technology that enables the design of magnetic resonance-based wireless charging systems that can simultaneously recharge various types of portable electronic devices. Details of this technology are being presented at the 2010 conference of the Institute of Electronics, Information and Communication Engineers (IEICE), opening September 14 at Osaka Prefecture University.

Electromagnetic induction and magnetic resonance are the methods most often used for wireless charging. With electromagnetic induction, a magnetic flux is induced between the power-transmitting and power-receiving coils, and operates based on electromotive force. This method has been used in cordless phones, among other equipment. The drawbacks are that the method only works over short distances, and the power transmitter and power receiver need to be in alignment, so it is effectively no different than using a charging station with a wired connection. By contrast, the magnetic resonance method, which was first proposed in 2006, uses a coil and capacitor as a resonator, transmitting electricity through the magnetic resonance between the power transmitter and power receiver. This method can transmit electricity over a range of up to several meters, and because a single transmitter can power multiple receiving devices, developments are under way for a broad range of potential applications, charging everything from portable electronics to electric cars.

What Fujitsu Laboratories has done is to develop technology that dramatically shortens the time required to design transmitters and receivers for magnetic resonance charging systems and, in addition, enables accurate tuning of resonant conditions in the design phase, even for compact transmitters and receivers that are prone to influences from nearby metallic and magnetic objects.

Fujitsu plans to continue using this analysis and design technology in research and development on wireless charging systems for mobile phones and other portable devices, and plans to bring products using it to market in 2012. The company is also looking at applying the results of this work to fields other than portable electronics, including power transmission between circuit boards or computer chips, and providing mobile charging systems for electric cars.
