A 40-year-old British doctor touring South Africa was shot and killed in Cape Town after turning into Ntlangano Crescent during violent street protests, authorities said. The incident occurred last Thursday when the general practitioner took a different route after leaving the airport. Multiple unidentified suspects confronted him and opened fire; he did not survive. South African police confirmed the death and said they were investigating the circumstances and seeking the attackers.

During the 2020 lockdown, researchers at the University of East Anglia studied 463 infants aged about eight months to three years to examine nap habits and learning. They tested vocabulary and other cognitive measures and tracked how often and how long children slept. The study found that some children consolidated information during sleep and therefore napped less often, while others who had smaller vocabularies napped more frequently and for longer periods.

Scottish nationalists argue that Scotland shares more in common with Nordic countries than with the rest of the United Kingdom. A YouGov poll found that between 52% and 61% of prospective SNP voters say Denmark, Finland, Iceland, Norway or Sweden are somewhat similar to Scotland, while only 31% of that group say England is similar. Those views are often cited to support calls for closer social and political alignment with Scandinavian models.

In 2009 the Large Hadron Collider (LHC), a giant particle accelerator near Geneva run by CERN, was preparing to restart after upgrades. Scientists said the machine would smash protons together at very high energies to study fundamental particles and forces, potentially revealing phenomena such as the Higgs boson or signs of new physics. However, some members of the public expressed fear that the machine could produce catastrophic effects, including miniature black holes or other unknown dangers.
