How does the Zika virus cause microcephaly? Why do some people develop schizophrenia or mental disease while others don’t? Is our sexual orientation hardwired in our genes? As seemingly unrelated as these questions might sound, they can all be addressed using the same scientific tool: twin siblings. Nancy Segal (Boston, 1951) has been chasing twins […]
Legend goes that the Greek poet Simonides of Ceos was having dinner at the house of a wealthy man in Thessaly when he received a message to go outside to meet two men who had requested to see him. When he left the room, the roof collapsed, killing the host and all the other guests […]

If you have ever tried to lose weight by exercising you probably know is not that easy. However, you might be happy to know that the problem is not only a matter of motivation. It’s been consistently reported that the effect of exercise on weight is surprisingly smaller than what theory would predict. The reasons […]
Men have been drowning their love sorrows in alcohol since the dawn of times. What probably none of those lonely broken-hearted drinkers might have imagined, is that their despair would serve as inspiration for an interesting research involving sex, alcohol and flies. As the story goes, a group of researchers at the University of California […]
The definition of life is not a simple one. According to classical textbooks, “living things are born, grow, reproduce and die”. But one doesn’t have to look too far to find some caveats in this interpretation. For example, when bacteria divide, can we really say that one is “giving birth” to the other? The part […]
Music is usually considered as a universal art form. It is found in virtually all human cultures and its use is associated with many different human tasks, from the most sacred to the most profane. Its elusive nature has haunted thinkers for millennia. Aristotle, Plato and Pythagoras, among others, devoted much of their time to […]
Improvisation is a hallmark of jazz music, arguably its most salient feature. When they improvise, musicians compose and play simultaneously, one of the most notorious examples of spontaneous creativity. What happens in the brain during improvisation is largely a mystery, but studying it may help us gain some insight on the basis that underlie the […]
There is a theory in criminology that says that if a broken window in a building is left unrepaired, that building will soon have all its other windows broken. The rationale behind it is that signs of urban disorder and untended public spaces elicit antisocial behaviour. The idea is reminiscent of the concept of “criticality” […]
More than a hundred years have passed since the German physicist Alois Alzheimer associated the traits of dementia of one of her patients with morphological changes in her brain after her death. While we know a great deal about what today is known as Alzheimer’s disease, we still need to answer two fundamental questions: what […]
Looking for a sexual partner outside your species is not very common, but that is what the males of a type of spider mite do. Even more, a recent work suggests that this kinky behaviour could have been key to colonization of new environments. Tetranychus evansi is a species of red spider mite originally from […]
