Epilepsy is a brain disorder that arises from imbalances of brain chemicals called neurotransmitters. This disorder manifests as recurring seizure, unconsciousness and momentary loss of memory. These events are frequent and unpredictable. This is because the brain cells called neurons either overwork or are unable to balance the release of two chemicals that are vital for normal brain function: gamma aminobutyric acid and glutamate.

The burden of epilepsy in Nigeria is high, with estimated prevalence of eight per 1,000 people.

I’m puzzled as to why the planets, stars and moons are all round (when) other large and small objects such as asteroids and meteorites are irregular shapes?

— Lionel Young, age 74, Launceston, Tasmania

This is a fantastic question Lionel, and a really good observation!

When we look out at the Solar System, we see objects of all sizes — from tiny grains of dust, to giant planets and the Sun. A common theme among those objects is the big ones are (more or less) round, while the small ones are irregular. But why?

On July 15 971, the bones of St Swithin were removed from their resting place on the order of Aethelwold, Bishop of Winchester, and placed in a shrine inside the cathedral. The saint, it seemed, did not approve. A violent storm followed, and rain fell for 40 days. And from that story came the belief that the weather on July 15 predicted a summer of sun or rain.

St Swithin’s day if thou dost rain’
For forty days it will remain;
St Swithin’s day if thou be fair,
For forty days will rain na mair.

Education Secretary Gavin Williamson has announced the end of school “bubbles” in England from July 19, following the news that 375,000 children did not attend school for COVID-19-related reasons in June.

Under the current system, if a schoolchild becomes infected with the coronavirus, pupils who have been in close contact with them have to self-isolate for ten days. In some cases, whole year groups may have to self-isolate.

When I was a child growing up in Kolkata, I would hear stories about the European colonisation of Bengal – the precolonial name of India’s West Bengal. These were selective narratives from a particularly male perspective, and presented colonisers as transforming social benefactors installed to provide a civilising influence. The rich histories of Indian philosophy that were once associated with religion, education and health were replaced by the colonial philosophy of conversion, modernising and improvement.

Due to unanswered questions into the origins of the coronavirus pandemic, both the U.S. government and scientists have called for a deeper examination into the validity of claims that a virus could have escaped from a lab in Wuhan, China.
