Jordanian State television has confirmed that the country’s air force pilot who was captured by Islamic State militants has been killed. The group released a video that purported to show Moaz al-Kasasbeh being held in a metal cage surrounded by oil then the fuel is lit and the pilot is pictured burned alive. He was captured after he crashed near IS strong-hold while taking part in US-led operations over northern Syria. King Abdullah of Jordan called the pilot a hero who died defending his country.

Brilliant pilot Moaz died defending his beliefs, homeland and nation. He joins all the martyrs who made ultimate sacrifice before him, for dear Jordan. Today, we stand shoulder to shoulder with the family of the martyr hero Moaz, with our people and our armed forces in this tragedy.

Speaking in Washington, President Obama said a different video of the murder was authentic and was a further indication of barbarity of IS. He added that the killing would re-double the determination of the US-led coalition to defeat the militants.

Members of Parliament in Britain have voted overwhelmingly in favor of controversial scientific technique that would allow the creation of babies using DNA from three people. If the measures were approved by the House of Lords, Britain would become the first country to legalize the procedure. Scientists say it could prevent children inheriting certain life threatening diseases. Here’s our health correspondent James Gallagher explains:

Doctors want to create babies from two women and one man in order to prevent deadly genetic diseases. The aim is to correct defects in a tiny shortage in the body that convert food to usable energy. These mitochondria are passed only from mother to child. The scientist's solution is to combine the parents’ DNA with a healthy mitochondria from a donor woman. Evidence suggests the technique would be safe but nobody can be certain. It also raises ethical questions.

The Ratings agency Standrad & Poor’s has to paid nearly 1.4 billion dollars to the US authorities to settle a legal claim that it knowingly inflated its ratings of mortgage investments. The ratings were issued over several years on the Subprime mortgage bonds that triggered the financial crisis of 2008. The US attorney general Eric Holder said the agency’s actions have been a factor in the crisis.

“On more than one occasion, the company's leadership ignored senior analysts who warned that the company had given top ratings to financial products that were failing to perform as advertised. As S&P admits under this settlement, company executives complained that the company declined to downgrade underperforming assets, because it was worried that doing so would hurt the company's business. This strategy did major harm, major harm to the larger economy, contributing to the worst financial crisis since the Great Depression. US attorney general Eric Holder.

医生们希望用两名妇女和一名男子来制造婴儿，希望能避免致命的遗传疾病。其目的是纠正身体内有缺陷线粒体，线粒体能将食物转化为可用能量。这些线粒体只能由母亲传给孩子，科学家的解决办法是将父母的DNA加入有健康线粒体的捐赠妇女的DNA。有证据表明这项技术安全，但没有人能确定，同时还引发了道德质疑。
