A bit of a slow start for the year in terms of science news so I’ll have to make do with some softer research articles. All three of the articles are about human psychology. First a short one about how chess grandmasters use their brains. Next, one about how men and women respond to stress differently when under the effects of caffeine and finally an odd look at how having a name that with starts with a letter at the end of the alphabet influences human behavior.
The first article is from New Scientist which talks about how Merim Bilalic at the University of Tübingen in Germany used an MRI machine to look at the brains of various chess players while they were looking at images of geometrical shapes or identifying whether certain situations in chess amounted to a check. Half of these were just novices and the other half were all internationally acknowledged grandmasters.

The second one demonstrates that humans really are that irrational when it comes to making economic decisions. The last one is on how caffeine might hold the key to curing Alzheimer’s disease.
The first article is from The Economist and covers a theory by Randolph Nesse of the University of Michigan. Dr. Nesse thinks that depression can be thought of as being analogous to physical pain.

By this, he means specifically the pursuit of unreachable goals. Since pursuing goals that are ultimately unreachable wastes precious time and energy, he theorizes that depression exists as a mechanism to inhibit doing so.
