A study out today has shown that marmosets, like humans, can and do act truly altruistically (see refs). Altruism is a hot topic in evolution. True altruism would, on the face of it, reduce an individual's reproductive fitness, and so you might expect that natural selection would weed out any altruists.
As the Stanford Encylopedia of Philosophy puts it:
... by behaving altruistically an animal reduces its own fitness, so should be at a selective disadvantage vis-à-vis one which behave........ Read more »

Today’s reading delves deep into the visual system, so hold your breath and get ready to dive in. It’s “Sound-aided Recover from and Persistence Against Visual Filling-in” by Bhavin Sheth and Shinsuke Shimojo of Caltech (Vision Research, 2004). I even found a PDF link for this one.

Many studies have showed that that media with violent or aggressive content (such as violent videogames) may increase aggressive behaviour and thoughts (Bushman & Huesmann, 2006). Moreover, music and lyrics can influence people’s behaviour; prosocial songs were found to be associated with a significant increase in tipping behaviour (Jacob, Guéguen & Boulbry, 2010), male customers [...]...

Chronobiologists at Cambridge have discovered circadian rhythms in peroxide oxidation in HUMAN blood cells. That sounds cool, right? But what if I told you that this research will forever make us rethink the innerworkings of the circadian clock because this is the first documentation of non-transcriptionally driven circadian rhythms...

From 2011 to December 2015, five women fought the Japanese Government all the way to the country’s Supreme Court. They were seeking to change a law that compels couples to adopt the same surname in order to legally register their marriage. Although the law does not specify whose name it should be, in practice, 96% of couples take the husband’s name, and the women argued that this made the law unconstitutional, since it violated their basic civil rights........
