Electromagnetic pulses lasting one millionth of a millionth of a second may hold the key to advances in medical imaging, communications and drug development. But the pulses, called terahertz waves, have long required elaborate and expensive equipment to use. (more…)
ANN ARBOR — A team of scientists from the University of Michigan, Duke Medicine and Stanford University has determined the underlying architecture of a cellular signaling complex involved in the body’s response to stimuli such as light and pain.
This complex, consisting of a human cell surface receptor and its regulatory protein, reveals a two-step mechanism that has been hypothesized previously but not directly documented. (more…)
