theory of evolution by descent, anomalies of these patterns are revealed by the 'minority report' of horizontal exchange. To understand the influence of horizontal gene transfer on the microbial tree of life, they focused on the network of vines cour...

model of cell mechanical behavior had pictured the cell as a viscous fluid core contained by an elastic cortical membrane, but their findings did not at all conform to that picture. The team's experiments show that the cell is a strange intermediate ...

Audiovisual integration of speech falters under competing demands for attention

example of how vision and audition come together is speech perception. Although we tend to think of speech as a purely auditory process, it is surprisingly sensitive to visual influences. This is quite evident when we try to follow a conversation in ...
