Record-breakers in the news today
Former South African President Nelson Mandela is making "steady improvement" under treatment for pneumonia, doctors have said.
The 94 year old Nobel Peace Prize recipient served as South Africa's President from 1994 to 1999, after 27 years 6 months 6 days in prison - the longest period of incarceration for a future head of state.
His current wife, Graca Machel, is the first female to be First Lady of more than one country, having previously been married to the President of Mozambique before his death in 1986.
Muppet's designer Jane Henson (former wife of Jim Henson) has died aged 78 after a battle with cancer.
She helped design many puppets for the hit TV show, as well as performing as a puppeteer. The Muppets went on to be enshrined with a star on Hollywood's walk of fame - although Mickey Mouse was the first fictional character honoured on the Hollywood Walk of Fame.
Henson also appeared on Sesame Street, which featured many of her creations. Sesame Street has the most daytime Emmy awards, receiving a record 122 since 1984.
Former Chelsea striker Didier Drogba has ignited speculation that former manager Jose Mourinho may return to the premiership club.
Drogba, who played under Mourinho's guidance during his three year spell at Stamford Bridge, says he feels the Portugese manager has "unfinished business" with Chelsea, and that his failure to win the Champion's League with the club could tempt him back.
This may be a powerful draw indeed, as Mourinho has not experienced much failure during his career - formerly the highest paid football manager at Chelsea, the club was also part of his nine year longest unbeaten home run for a football manager.
Between 22 February, 2002 and 19 February, 2011, clubs managed by Mourinho - Porto (Portugal), Chelsea (UK), Inter Milan (Italy) and Real Madrid (Spain) - failed to see a single home defeat.
President Barack Obama today launched a new "brain-mapping" project from the White House.
An initial $100 million investment aims to achieve for research into the brain what the Human Genome Project has done for genetics, helping to give insight into diseases such as Alzheimer's and epilepsy.
The heaviest human brain on record was that of a 30-year-old male (USA), which weighed 2,300 g (5 lb 1.1 oz) - but that is six times lighter than the heaviest brain of any animal, which belongs to the sperm whale.
A sperm whale's brain weighs approximately 9 kg (19 lb 13 oz) - although this only equates to 0.02% of the whale’s total body weight!
