Protein fishing in America: The movie

...single-molecule spectroscopy technique gathers and analyzes photons emitted as single proteins interact. This raw data may not produce what we would think of as a motion picture, but for Lu it is just as good. It enables him to construct--in true sequence and in real time--the position and continuous motion o...

Applied Mathematical Models in Human Physiology

... Human Physiology is the only book available that analyzes up-to-date models of the physiological system at several levels of detail. Some are simple "real-time" models that can be directly used in larger systems, while others are more detailed "reference" models that show the underlying physiological mechan...

...ral minutes. The software developed for the method analyzes three of the MRI images, one before and two after the injection (hence the name 3TP), and then creates a colored likeness of the breast or prostate area based on the resulting data. A preponderance of red in the picture indicates malignancy, while ma...

UCLA physicists create nanoscale sensor

...chnique called "evanescent wave scattering," which analyzes light that leaks out behind a reflecting mirror. This evanescent wave can be used to sense precisely the position of an object "beyond" the mirror. "Instead of detecting the presence of the target, we detect the changing conformation of the probe wh...

A tiny pump promises big time performance
