From AI with Hannah Fry to David Attenborough's early days, these are the five must-watch science documentaries of the year to date, says Bethan Ackerley In 2015, an amateur trophy hunter from the US shot and killed the largest lion in Africa. The vitriol unleashed after Cecil's death isn't surprising (or entirely unwarranted), but what is remarkable is how this delicately-crafted film uses the case as a locus for all sorts of arguments about conservation. A symbol in life and in death, Cecil and other large, charismatic animals exist in a complex balance with humans who, one way or another, invariably stake a claim on them. Almost everyone in the world now needs to have some knowledge of how AI technologies work, from all the chatbots they encounter to driverless cars and more. Mathematician Hannah Fry is an excellent person to impart such knowledge: across three episodes, she guides us through recent cases where AI has become entangled with very human problems.

Sudanese women gather for a hot meal in al-Rahmaniyah camp for displaced people, near the city of El-Obeid in the southern Kordofan region of Sudan on Tuesday. Geneva - Misinformation and hate speech are inciting harm to refugees, with artificial intelligence exacerbating the spread, the United Nations warned Tuesday, as it urged tech giants to help turn the tide. However, if handled the right way, AI could be put to good use in managing humanitarian crises, said UNHCR, the U.N. refugee agency. UNHCR is taking part in the AI for Good Global Summit in Geneva, putting across its point that the world's major displacement crises are often twinned with "information crises". The summit is an attempt by the wider U.N. to focus on using AI's potential to serve humanity by solving global challenges, and to look at the state of AI standards.

El-Obeid under siege by RSF: Could this be Sudan's next el-Fasher? Half a million people are trapped in the Sudanese city of el-Obeid, the capital of North Kordofan state, as the Rapid Support Forces (RSF) paramilitary group tries to enforce its dominance over the Kordofan and Darfur regions during a civil war that has wrought devastation on the country for three years. The Office of the United Nations High Commissioner for Human Rights has warned of an impending humanitarian "catastrophe" as el-Obeid is expected to be the next site for major ground clashes between the RSF and Sudanese military. Many countries have also raised the alarm about atrocities being carried out in the city. El-Obeid, which has been cut off by continuous drone attacks for months, is under threat after the mass atrocities carried out by the RSF in el-Fasher, capital of North Darfur state.
