Wash U Expert: High stock prices, low interest rates cause uptick in corporate tax inversions

The United States has the highest corporate income tax rate in the developed world. As a result, many U.S. companies are turning to tax inversions — reincorporating overseas by getting acquired by a smaller company in a country where the corporate tax rate is lower. Adam Rosenzweig, JD, professor of law and expert on international tax, examines why inversions are becoming so popular.

Unintended consequences: More high school math, science linked to more dropouts

Washington University researchers have found that courses intended to better prepare high school graduates for college also drive some students to drop out. They report that policies increasing the number of required math and science courses are linked to a higher dropout rate.

Finding quantum lines of desire

What paths do quantum particles, such as atoms or photons, follow through quantum state space? Kater Murch of Washington University in St. Louis has used a superconducting quantum device to continuously and repeatedly record the paths the device took through quantum state space. From the cobweb of a million paths, a most likely path between two quantum states emerged, much as social trails emerge as people round off corners or cut across lawns between buildings. The research is featured on the cover of the July 31 issue of Nature.

Wash U Expert: States should have some power over criminal laws of marijuana

A bill introduced July 28 in the U.S. House of Representatives would amend the controlled substances act – the federal law that criminalizes marijuana – to exempt plants with an extremely low level of THC, the part of marijuana that makes users high. Following closely on the heels of a call by the New York Times editorial board for the federal government to legalize marijuana, this could mark a turning point of sorts in the campaign for legalization. Gregory P. Magarian, professor of law, sees two reasons for leaving states with some power over the criminal law of marijuana.

Many depressed preschoolers still suffer in later school years

Children diagnosed with depression as preschoolers are likely to suffer from depression as school-age children and young adolescents, research shows. Depressed preschoolers were 2.5 times more likely to suffer from depression in later school years than children who were not depressed at very young ages, according to School of Medicine researchers.
