Here we report the generation of Tre recombinase through directed, molecular evolution. Tre recombinase recognizes a pre-defined target sequence within the LTR sequences of the HIV-1 provirus, resulting in the excision and eradication of the provirus from infected human cells. While still in its infancy, directed molecular evolution will allow the creation of custom enzymes that will serve as tools of molecular surgery and molecular medicine.

This protocol describes a method to test the hypothesis that the reversal of the effective geomagnetic field (GMF) induces differential gene expression and alters the morphology of Arabidopsis thaliana. A triaxial octagonal system of Helmholtz coil-pairs was used to artificially generate reversed GMF conditions in the plant growth chamber.

An experimental method to examine the early plasma evolution induced by ultrashort laser pulses is described. Using this method, high quality images of early plasma are obtained with high temporal and spatial resolutions. A novel integrated atomistic model is used to simulate and explain the mechanisms of early plasma.

The Wave Nature of Light

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion. Others in the...

Standing Waves

Source: Arianna Brown, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA Standing waves, or stationary waves, are waves that appear not to propagate and are produced by the interference of two waves traveling in opposite directions with the same frequency and amplitude. These waves appear to vibrate up and down with no linear movement and are most easily identified in vibrating finite media like a plucked guitar string,...
FAQs
The governing wave equations provide the framework for predicting how a field changes, while material properties, geometry, boundary conditions, and source behavior determine the result. These factors control the permitted propagation and interactions within an engineered system. Changing one can alter the calculated spatial or temporal pattern, so accurate system specifications are essential when modeling wave behavior.
Reflection and refraction redirect wave behavior at boundaries, whereas diffraction spreads a field around geometric features and interference combines contributions from multiple wave paths. These mechanisms can occur together, making the resulting field more complex than a single propagating pattern. Distinguishing them helps engineers interpret direction changes and field structure in optical, acoustic, and electromagnetic systems.
Amplitude, phase, frequency content, and direction provide complementary measures of evolution. Amplitude indicates changes in field strength, phase tracks positional or timing relationships, frequency content shows how the signal’s spectral composition changes, and direction describes its travel. Examining these quantities together helps connect observed patterns with energy transfer and with the effects of system geometry or materials.
A practical analysis combines numerical modeling with experimental measurement. Engineers first represent the relevant source, medium or engineered structure, geometry, and boundary conditions, then use a model to predict field behavior. Measurements can reveal the actual amplitude, phase, frequency content, or direction and provide a basis for evaluating the prediction. This comparison supports refinement of the system analysis.
Wave field evolution is particularly useful when engineers must predict signal behavior in optical fibers, acoustic devices, electromagnetic systems, or structural materials. In each case, the analysis can show how propagation and interactions modify the field as it moves through the system. Those predictions support choices involving communication technologies, sensors, imaging systems, and components designed to control or mitigate wave-driven effects.
Engineering applications use the resulting field information for both performance and protection. Communication and imaging systems can be designed around predicted signal changes, while sensors can exploit measurable field behavior to obtain system information. In structural materials and other components, the same analysis helps identify or manage wave-driven effects. The value lies in linking physical evolution to design decisions.
