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.

Nov. 7, 2013: Pakistani Taliban leader Mullah Fazlullah is seen on television at a coffee shop in Islamabad. The Pakistani Taliban leader known for beheading police officers and even ordering the assassination of Nobel Peace Prize winner Malala Yousafzai has been killed by a U.S. drone strike, Afghanistan's Defense Ministry says. Mohammad Radmanish told the Associated Press on Friday that Mullah Fazlullah, the ruthless insurgent leader, died along with two other terrorists a day earlier in the Marawara district along the Afghanistan-Pakistan border. A statement attributed to U.S. Forces-Afghanistan spokesman Lt. Col Martin O'Donnell said an American "counterterrorism strike" was carried out in the region targeting "a senior leader of a designated terrorist organization," but did not say whether it had killed anyone. Fazlullah previously ordered the bombing and beheadings of dozens of opponents when his band of insurgents controlled Pakistan's picturesque Swat Valley from 2007 until a massive military operation routed them in 2009.
