Twist and Turn: Weak Lensing Image Distortions to Second Order

We account for all the image distortions relevant to weak gravitational lensing to second order. Besides the familiar shear, convergence, rotation and flexions, we find a new image distortion with two distinct descriptions, the twist and the turn. Like rotation, this distortion is not activated gravitationally to first order, but will be activated by systematic effects. We examine the rotationa...

New corn technology: scientists are all eyes and ears.

Corn and other crops contaminated with the fungus Aspergillus flavus give off a carcinogenic by-product called aflatoxin, which is blamed for high rates of liver cancer in Asia and Africa, where rice and corn are food staples. In the United States, aflatoxin's major threat is to farm animals, which can get sick or even die from consuming too much of the toxin. Scientists are working on ways to ...
