Hello Nature readers,
Today we hear why scientists are standing up against US President Donald Trump’s controversial policy of taking children from their parents at the US border, meet IBM’s debate-bot and celebrate 20 years of the ‘small-world’ effect.

Child-health researchers and pediatricians are speaking out against US President Donald Trump’s controversial policy of taking children from their parents at the US border. The American Academy of Pediatrics said the practice “can cause irreparable harm to lifelong development” and “contradicts everything we stand for as pediatricians”. Child-development researcher Jack Shonkoff points to the “wear and tear effect biologically” of long-term separations. “They’re not flailing and screaming, [but] underneath in their bodies, their stress system is still highly activated — silently, invisibly.”

FEATURES & OPINION
The idea that everyone in the world is connected to everyone else by just six degrees of separation was explained by the ‘small-world’ network model 20 years ago. What seemed to be a niche finding later proved to be the key to understanding the structure of the World Wide Web and how anatomical and functional areas of the brain communicate with each other.
In the ‘small-world’ effect, links between nodes of a network (a) are rewired at random. Eventually, an increasing number of short cuts (red lines) connect distant nodes in the network (b).
