If you've always wondered what it takes to be a badass, a new study reveals the strict criteria. Following questionnaires involving over 2,000 people, researchers in the US have officially improved on the dictionary definition of the term. A badass has an'outer toughness' (consisting of physical strength, a'formidable presence', or both), an inner toughness (such as moral resilience and courage), or both. That's why'radically' different men and women – ranging from peace advocates to fierce warriors – can be considered badasses, according to the experts. Famous badasses include Genghis Khan (AD 1162 to 1227), the brutal founder of the Mongol Empire responsible for the deaths of around 40 million people, they say.

How do you get every single girl a full 12 years of quality education? That's the question at the heart of the Malala Fund, the organisation set up by Malala Yousafzai, the young Nobel Prize winner. And she wants to provide this education in parts of the world where it can't be taken for granted. Luckily, she has a powerful ally. In January, Apple revealed a tie-up with Malala Fund as part of the initial goal of getting 100,000 girls into education in Afghanistan, Pakistan, Lebanon, Turkey and Nigeria. But today it has been announced that the collaboration is expanding to Latin America. This expansion means grants will be offered to advocates in Brazil, who will join the Malala Fund's network of so-called Gulmakai Champions.

KABUL – President Ashraf Ghani confirmed Friday that Pakistani Taliban chief Maulana Fazlullah has been killed in a U.S. drone strike. Fazlullah is believed to have ordered the failed 2012 assassination of Malala Yousafzai, who became a global symbol of the fight for girls' rights to schooling, and who later won the Nobel Peace Prize. U.S. forces targeted Fazlullah in a counterterrorism strike Thursday in eastern Kunar province, close to the border between Afghanistan and Pakistan, U.S. officials said, without confirming his death. "I spoke with Prime Minister of #Pakistan Nasir ul Mulk and Chief of Army Staff General Qamar Javed Bajwa and confirmed the death of Mullah Fazlullah," Ghani tweeted, adding: "His death is the result of tireless human intel led by #Afghan security agencies." Ghani added the Pakistani leaders had assured him the strike was "a great step toward building trust between the two nations," while urging them to "bring (the) Afghan Taliban residing in Pakistan to the negotiation table."
