Researchers today announced the creation of an imaging technology more powerful than anything that has existed before, and is fast enough to observe life processes as they actually happen at the molecular level.
Chemical and biological actions can now be measured as they are occurring or, in old-fashioned movie parlance, one frame at a time. This will allow creation of improved biosensors to study everything from nerve impulses to cancer metastasis as it occurs.
The measurements, created by the use of short pulse lasers and bioluminescent proteins, are made in femtoseconds, which is one-millionth of one-billionth of a second. A femtosecond, compared to one second, is about the same as one second compared to 32 million years.
