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.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
