As the UK prepares to celebrate Einstein Year in 2005, a physicist from Bristol University is looking for stories that can be used to tell taxi drivers what physics is all about. Sir Michael Berry, whose own father was a London cabbie, thought of the idea after failing to give a taxi driver a clear explanation of what it is that physicists actually do. Berry realized that physicists need a stock of good and convincing stories that show how physics affects peoples lives. Looking back, he now wishes that he had told the driver how physics has democratized music, by creating the laser, which allows music to be played on a CD almost anywhere. Berry also wishes that he had said how physics has led to GPS navigation devices - the first consumer product to take advantage of Einsteins general theory of relativity. The best stories will be published in a future issue of Physics World.
Radiation – how much is good for you?
Anti-nuclear activists have always argued that even a tiny dose of radiation is bad for the human body. But according to a radiation biologist at Washington State University in the US, that view may be wrong. Antone (Tony) Brooks, who is involved in a low-dose research programme sponsored by the US government, says that the impact of small amounts of radiation is much more complicated than previously suspected. They have a cocktail-like mixture of beneficial and harmful effects that can, on balance, be harmless below a certain threshold. As Robert P Crease explains, this change of view could have huge social and economic consequences.

In the field of nanoscience, an international team of physicists with participants from Konstanz has achieved a breakthrough in understanding heat transport
Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
