Stephen Hawking once sent his PhD student away with a very hard problem – finding exact rotating black hole solutions of Einstein’s equations with a cosmological constant – and was stunned when he came back a few days later with the solution

I was a student of Stephen Hawking’s – here’s what he taught me Like many students of my generation, Stephen Hawking had already had enormous influence on me long before we ever met. When I was hesitating about my A-level choices, it was his book A Brief History of Time that convinced me to continue …

A key symptom of depression is anhedonia, typically defined as the loss of ability to experience pleasure. It is a core feature of depression, but it is also one of the most treatment-resistant symptoms. Using ketomine, researchers found over-activity in the brain blunting reward seeking

Marmoset study gives insights into loss of pleasure in depression ‘Anhedonia’ (the loss of pleasure) is one of the key symptoms of depression. An important component of this symptom is an inability to feel excitement in anticipation of events; however the brain mechanisms underlying this phenomenon are poorly understood. Now, in a study involving marmosets, …
