Today marks the 65th anniversary of the first nuclear power generation anywhere in the world, at Calder Hall on the Sellafield site in Cumbria, UK.

A thread on how New Scientist saw the dawn of nuclear power...
The first issue of (The) New Scientist was published 3 months later. In it, T.A. Margerison asked “where do we go from Calder Hall?” The article called for a vast stepping-up of the UK’s atomic energy programme, but its predictions proved wide of the mark.
“Coal, as we all know, is scarce and expensive. It can be expected to become more so as the easier-worked seams are exhausted.” This situation proved to be short-lived, and we now have the opposite problem. books.google.co.uk/books?id=X6Xez…

Unlike a computer, the human brain is exquisitely sensitive to the context in which in operates. Here are some of the ways your environment can affect the way you work 🧵
Signals embedded in a space communicate to occupants that they are welcome there – or not. For example, female students were much more interested in studying computer science after spending time in a non-stereotypical classroom.
A sense of ownership also has a big impact. When people occupy spaces that they consider their own, they feel more confident and capable. They are also more efficient and productive, less distractible and they advance their own interests more forcefully and effectively.

While global figures vary, it is thought that about 14 per cent of people who catch covid-19 end up with lasting symptoms – which is some 25 million people worldwide. For some, symptoms have persisted for over a year. #LongCovid
One puzzling feature is that those most prone to #LongCovid aren’t those most likely to get sick from the initial infection. Women are 30 per cent more likely to get it than men, and 35 to 69-year-olds are the age group most often affected, according to the @ONS.
One report suggests people with #LongCovid can be divided into four groups: those experiencing the after-effects of ventilation in intensive care; those with organ damage caused by the virus; those with post-viral fatigue syndrome; and a miscellaneous group with varying symptoms.
