Quite a few articles for reading this past month:

•  Starting with this article from Big Think that provides some insight about how humans can make economically irrational decisions, in this case, the tendency of people to overvalue the things that they already own, a phenomenon known as the “endowment effect”. It cites research showing how Hadza Bushmen in Tanzania who have no contact with the modern economy do not experience the effect. But once roads have been built to connect their isolated communities to tourists, they become involved in the modern economy quickly pick up the effect.
• The next one is from Bloomberg and covers research into implantable probes that can help people who have suffered memory losses to recover some of what they have lost. It’s designed for soldiers who have suffered injuries however and works only to help with lost motor skills rather than abstract knowledge-type memories, but it looks like a promising start.
• This next one is a favourite of mine. Researchers already know that when people experience art such as a painting or music, certain parts of the brain are activated and this can be detected using  MRI scans. This article from the BBC shows how the brains of mathematicians are activated in similar ways when contemplating mathematical formulas. In fact, the more aesthetically pleasing the formula is, the greater the response measured, with the most beautiful formula of all being of course Euler’s identity.
• Science has long known that more physically attractive people tend to achieve greater success in a wide variety of fields, many of which are seemingly unconnected with beauty. This article from The Economist tries to tease out these effects by studying participants in the Tour de France bicycle race. Subjects were asked to rate the attractiveness of Tour de France contestants without knowing about the performance of the contestants. The researchers found that physical attractiveness is indeed correlated with being better cyclists in a field in which there should be no bias towards attractive people. The working idea is that physical attractiveness is itself an indicator of good genes and good health, and hence better performance at sports.
• Here’s another article from the BBC that talks about research that allows one monkey to control a limb of another monkey. The monkey being controlled and electrodes were inserted in its spinal cord. The master monkey had a brain chip implanted which could monitor the activity of its neurons. The readings were then fed to the sedated monkey, allowing the other monkey to control its limb.
• This great article from BPS Research Digest goes into detail about researchers’ attempts to circumvent the inability of people to tickle oneself. They implemented a body swap illusion in which the participants wore goggles that showed video feed from a camera. They were seated opposite an experimenter and the camera would either show a normal forward facing view or a view of themselves from the perspective of the experimenter. Both the participant and the experimenter held a rod with a foam at the other end which could be used for tickling. The idea is that the subject would be confused about who was doing the actual tickling. It turns out even when the subjects were completely fooled by the illusion, they still found it impossible to feel a tickling sensation when it was really their own hand moving the rod but did feel it when it was the experimenter’s hand moving.
