Belarus opposition leader jailed for 18 years

His wife, Svetlana, stood against the Belarussian president Alexander Lukashenko in last year's election; she tells us "it's no time to sit and cry". Also: record-breaking temperatures have been recorded in the Arctic; and why brain surgeons and rocket scientists may not be quite as smart as we thought.
