By guest blogger Laura SpinneyWhat were the greatest human catastrophes of the 20th century? When asked this question, most people answer the Second World War, followed by the First World War. The former killed around 50 million people, the latter 17 million. But there was another catastrophe that dwarfed both of these, that is rarely mentioned. The influenza pandemic of 1918-1920, better known as the Spanish flu, killed at least 50 million people worldwide, and perhaps as many as 100 million.Wh........ Read more »

Challenging behaviours or behavioural crisis in relation to autism is a topic that has graced this blog before (see here). Covering a whole spectrum of issues ranging from aggression (self and/or directed against others) to various other quite undesirable presentations (such as smearing) quite a lot of behaviour can potentially fall into this description.Without heading too far into the possible [often very individual] reasons as to why challenging behaviours occur and their meaning (see he........

Memory capacity of brain is about 10 times more than previous estimations, which is in the petabyte range, i.e. almost equivalent to the entire Web.
Memories and thoughts in our brain are caused by a distinct pattern of chemical and electrical activity. Our brain has branches of neurons, which are connected to each other through synapses. Signals and information travel through these synapses with the help of neurotransmitters. Each ne........ Read more »

Capgras syndrome is a strange disorder in which the sufferer becomes convinced that someone close to them has been replaced by an impostor.
Yet now, a new and even stranger variant of the syndrome has been reported - "Cat-gras". This is the name coined by Harvard neurologists R. Ryan Darby and David Caplan in a new paper in the journal Neurocase. The authors describe the case of a man who believed that his cat was in fact a different cat.
According to Darby and Caplan, the patient ... Read more »

While working on my doctorate, I lived for a time in an apartment just down the street from a small wastewater treatment facility. I never noticed a bad smell, but if I stayed up too late I'd end up having to fall asleep to the very low pitched rumble of gallons upon gallons of poop water being pumped into and out of large tanks. I tried not to think too hard about this, which tends to be difficult when you're, y'know, trying to fall asleep.Wastewater treatment facilities, or sewage treatment pl........ Read more »

If you’re wondering who to appoint to run a team with creative goals, you might favour a non-creative, reasoning that it’s down to the team members to generate creativity, with the person at the top acting more as driver and dogged coordinator. However, new research in Organizational Behavior and Human Decision Processes suggests that teams produce more creative outcomes when their managers have greater confidence in their own creativity.Lei Huang of Auburn University and his collaborators s........
