Article Abstract:
Biologists are increasingly having to manage large amounts of data and are turning to tools from the physical sciences. Many physicists in turn are tackling significant questions in biology using both the mental and physical tools of physics. Collaboration has sometimes been hampered by language, and the problem of finding common ground. However several US universities have plans to bring physical scientists and biologists together, and some physics and biology departments are making joint appointments, while government and private funding agencies in the US are promoting the physics-biology agenda.

Article Abstract:
It is becoming increasingly common for top cell biologists, geneticists and molecular biologists to work with experts in magnetic resonance imaging, optical imaging and positron emission tomography. It has been possible to develop chemical probes to make molecular targets 'light up' in magnetic resonance imaging, positron emission tomography or other optical images.

Article Abstract:
The motor domains of the proteins kinesin and myosin have similar structures although the proteins have very different properties. Such differences can be understood by analysing the fraction of time that a motor is fastened to its filament, known as the duty ratio. Understanding the constraints of duty ratios gives further insight into other motor proteins.
