Moving Beyond String Theory

Wired: Ask any credentialed nerd what the ultimate theory of physics is, and chances are they'll reply, "string theory."

In string theory -- an idea that's been around since the late 1970s -- the universe is a 10-dimensional place, with six of those dimensions curled up inside themselves like a cat in front of a fireplace. All particles and forces are different resonances and vibrations of these 10-dimensional strings.

China's exponential growth in nanotechnology

Universiteit van Amsterdam (UvA): A paper by Ping Zhou and Loet Leydesdorff suggests that China is rapidly developing research expertise in nanotechnology. Six years ago, US-based scientists published 50% of the papers in the journal Nanotechnology and China accounted for zero. Today 25% of papers in the journal are from US-based scientists and 15% from China. Zhou and Leydesdorff report that between 1999 and 2005, for 85 journals in the fields of chemistry, physics and material sciences that are relevant to nanotechnology, the number of papers published by China rose exponentially to 8.34%, while papers published by other countries either remained steady or declined. China's overall world share in science journals is 6.52%, suggesting that China is aiming to be at the forefront of research into nanotechnology.

NASA it's not, but desert spaceport nears first launch

The Christian Science Monitor: Visitors to Spaceport America must first navigate the frontier before reaching the final frontier.

Across dirt roads, through deep puddles, and past a few cows - where 4x4 is a way of life rather than an automotive trend - the outlines of a spaceport that will launch technology and people above Earth are just coming into view. For now, these 27 square miles of dirt one hour outside the town of Truth or Consequences mostly consist of two portable buildings, a corrugated steel shed, and two Port-A-Potties - one pink, one blue. Oh, and a launchpad, of course.

Branson Pledges to Finance Clean Fuels

NAS suggests scientific context for Moon exploration

The National Academies Press: Repairs to the space shuttle program and the Presidents vision for returning humans to the Moon and onwards to Mars is causing budget cuts to the science program at NASA. One aspect that is not suffering cutbacks are science missions related to the Moon/Mars vision. The National Academies of Science has taken a look at NASA's lunar precursor and robotic program to help formulate a comprehensive, validated and prioritized set of scientific research objectives for the Moon for the next 15 years. Their interim report, with a full report to follow in 2007, recommends that the primary science goals be related to a history of the Moon and Earth-Moon system; implications for the origin and evolution of the solar system, including the sun; and implications of all these for the origin and evolution of life on Earth and possibly elsewhere in the solar system. Many of the scheduled missions over the next 10 years by the China, US, India, Europe and Russia meet these research objectives. The committee recommends prioritizing research at the South lunar pole-Aitken basin, which is a proposed NASA mission that has yet to receive funding despite being a high priority in the 2003 NRC Decadal survey report. It also recommends creating a science research unit within the human exploration division to help better coordinate research goals with the objectives of returning humans to the Moon. The committee foresees an expansion of ground-based facilities that can receive lunar samples from robotic return sample missions as current facilities are inadequate. Finally the committee recommends that even if humans do return to the Moon, they should have an extensive array of robotic assistants to help with the science part of the mission, a tact acknowledgment that many of the missions related to the groups suggested research priorities are best done by robots.

Academia Told to Make Room for Women

ScienceNow: U.S. universities foster "a culture that fundamentally discriminates against women," says a report on the status of women in academic science and engineering issued today by the National Academies. Their underrepresentation is "deeply troubling and embarrassing," according to the report, which suggests that institutions should create a body to collect data, set standards, and ultimately monitor compliance to increase the number of women in technical fields.

First men, now women receive prosthetic arm prototype

The Washington Post: Claudia Mitchell, a resident of Ellicott City, Maryland has become the first women to receive a prosthetic arm that is similar in capabilities to a prototype arm worn by Jesse Sullivan that was mentioned earlier this month in Physics Today magazine. Mitchell is only the fourth person to receive a prosthetic arm that has three-degrees of movement that is controlled by re-wiring nerves that used to run along the upper limbs, to a muscle on the chest that twitches in response to nerve signals. The muscle twitches are picked up by electrodes placed on the chest, which in turn, controls the prosthetic arm. The prototype is built by the same physicians and engineers at the Rehabilitation Institute of Chicago who built Jesse Sullivan's arm. The technique for controlling the prostheses has additional difficulties for women due the amount of upper-body fat that rests on the muscles commonly used for this type of research. However, a new surgical technique and better, more sensitive electrodes has limited the potentially disfiguring aspects of the operations required to re-wired the nerves to the upper body muscles. Mitchell will be demonstrating her new limb at a conference in Washington DC later today.
