In case you missed them, here are my picks of the week from psychology and Neuroscience from ResearchBlogging.org:

Also, my column on SEEDMAGAZINE.COM this week covers the incessant battles microbes wage with each other — and how they affect us. Here’s a selection:

In 1928, when Alexander Fleming discovered penicillin, the antibiotic produced by the bacteria of genus Penicillium, it seemed that a “miracle cure” for many diseases had been found. But rather than being a mere medical triumph, penicillin’s discovery revealed more of the fundamental complexity to the microbial world. In fact, we now recognize penicillin’s effects as just the latest battle in an evolutionary war that microbes had been waging among themselves for at least hundreds of millions of years.

While it was true that antibiotics like penicillin were effective at treating a variety of diseases caused by bacteria, it was also true that these substances were not effective against all bacteria. Also, bacteria that were not initially resistant to antibiotics were proven capable of developing resistance over time. This was just the beginning. Even now, scientists are still unraveling the many different strategies and tactics bacteria employ in their warfare.
