The new study builds on previous work by Japanese researchers, who in 2005 reconstituted the cyanobacterial circadian oscillator, the basic 24-hour timekeeping loop of the clock. The oscillator ...

The presence of glucose in urine could be measured by adding a few drops of urine to a Clintest tablet in a test tube and charting differences in color. Clinitest more accurately measured the amount ...

Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells. The cyclical interactions of clock proteins keep the biological ...

Inside a test tube, literally trillions of possible solutions can be generated in parallel. The problems that can be solved, however, need to be rigidly specified.
