Japan's defence minister Gen Nakatani has said a purported Islamic State video that seems to show the murder of hostage Kenji Goto "appears genuine".
Professor Carl Djerassi, the chemist widely considered the father of the birth control pill, has died at the age of 91.
Professor Djerrasi died of complications from cancer at his home in San Francisco, Stanford University spokesman Dan Stober said.
He was most famous for leading a research team in Mexico City that developed norethindrone, a synthetic molecule that became a key component of the first birth control pill in 1951.
'The Pill', as it came to be known, radically transformed sexual practices and women's lives.
In his book, 'This Man's Pill', Professor Djerassi said the invention also changed his life, making him more interested in how science affected society.
Celtic and Rangers will face each other for the first time in almost three years today, with police warning supporters they will crackdown on any signs of trouble.
The League Cup semi-final match at Hampden Park in Glasgow is a sell-out and will have an international TV audience with 54 countries screening the game.
Tensions are set to be high in what is the first game between the clubs since Rangers' liquidation in 2012 and both clubs have been visited by Police Scotland to remind players and management of their responsibilities in a bid to minimise any possibility of trouble.
Officers have said they will be monitoring social media as well as having an increased presence on streets in and around Glasgow.
Police will be deployed at the stadium, in Glasgow city centre and at major transport hubs before, during and after the match.
Chief Superintendent Andy Bates, the match commander, said: "I am sure that most supporters will enjoy the sporting occasion, however a minority may choose to cause disorder and my message to them is clear: anyone involved in disorder will be arrested."
Kenji Goto's mother Junko Ishido has spoken of her grief after Islamic State released a video apparently showing the murder of her son.
Speaking to reporters after the video was released Ms Ishido broke down several times.
Mr Goto's brother, Junichi, also paid tribute to the journalist. He said: "I had hoped to give thanks for his return alive. But, as his brother, this outcome is very regrettable."
Details on new reforms to help rehabilitate offenders including support at the prison gate when they finish their sentence have been outlined by the Justice Secretary, Chris Grayling.
Mr Grayling said for the first time all offenders will be given "a proper chance at rehabilitation, instead of just leaving them to wander the streets and get on with it."
"For too long we have released prisoners back onto the streets with £46 in their pockets and little else than the hope that they would sort themselves out. It's little wonder things haven't improved - but now all this will change", Mr Grayling added.
The reforms include extra support for short-term prisoners under previously announced plans to boost rehabilitation, with a focus on helping them to beat drug and alcohol addictions and finding them jobs and homes.
Figures released by the MoJ show around 86,000 further crimes were committed by offenders released from sentences of less than a year in 2012, including more than 600 violent offences, just one month after release.
