Gene flow via seed or pollen is a basic biological process in plant evolution. The ecological and genetic consequences of gene flow depend on the amount and direction of gene flow as well as on the fitness of hybrids. The assessment of potential risks of transgenic plants should take into account the fact that conventional crops can often cross with wild plants. The precautionary approach in ri...

College students drink in consistent patterns over the course of the academic semester and year (Beets et al., 2009; Del Boca et al., 2004). However, it is unclear if there are naturally occurring groups of female Thursday drinkers who display their own unique patterns of drinking across the semester. In a fall semester 10-week mixed online- and paper-based study of college female drinking, cla...

For them, traditional biologists and medical scientists committed a gross scientific error by overlooking quantum physics as being too weird, mind bending and unpredictable for biological systems. The basis of quantum physics is that, at the sub-atomic level, matter does not exist with certainty. It only exists as a tendency to exist in particle or wave form as maybe yes or maybe no. This appli...
