World’s second-largest diamond ‘found in Botswana’ –
The world’s second-largest gem quality diamond has been discovered in Botswana, the Lucara Diamond firm says. The 1,111-carat stone was recovered from its Karowe mine, about 500km (300 miles) north of the capital, Gaborone. It is the biggest diamond to be discovered in Botswana and the largest find in more than a century.

Scientists have trained pigeons to diagnose breast cancer –
Doctors train for years in order to be able to correctly diagnose cancer – but could they soon be replaced by pigeons? Well, no. Obviously not. However, scientists have now discovered that pigeons are surprisingly adept when it comes to spotting cancerous cells. In a study led by Professor Richard Levenson of the University of California, pigeons were shown microscope images of breast tissue, and then rewarded with food if if they correctly pecked a coloured button that corresponded to either cancerous or healthy tissue.

Bangladesh: Government ‘mistakenly’ cuts off internet –
An internet shutdown in Bangladesh which lasted for more than an hour was a “mistake”, according to the authorities. Officials announced on Wednesday that access to Facebook, Viber and WhatsApp had all been blocked in the wake of a Supreme Court ruling upholding death sentences for two men convicted of war crimes. But the country’s Telecommunication Regulatory Commission says it accidentally cut off access to the internet across the whole country. The web blackout started at around 13:00 local time and lasted at least 75 minutes, according to the Bangladeshi newspaper The Daily Star. “We restored the internet as soon as we realised the mistake,” says Shahjahan Mahmood, the commission’s chairman. The messaging services were blocked as originally planned in order to maintain security, he says. [BBC]
