input with options: U.S. President Donald Trump attempted to reset his relationship with Africa on Monday, as he hosted Nigerian President Muhammadu Buhari. Buhari is the first sub-Saharan African leader to have a White House summit with Trump, who has been criticized for reportedly making derogatory comments about Africa. During his public remarks with Buhari, Trump focused mostly on common goals and shared interests, such as fighting terrorism and expanding trade. "We love helicopters he loves them more than I do," joked Trump, referring to his administration's decision to approve a $600 million military sales deal to Nigeria. Buhari thanked Trump for approving the deal, which the administration of former President Barack Obama had suspended over allegations of human rights abuses. "I worked it out so that now you can buy the helicopters that you want," Trump said, adding, "We make the best military equipment in the world, and our friends can now buy it." Human rights groups have accused the Nigerian military of torture, rape and extrajudicial killing in its almost decade-long campaign against the Boko Haram extremist group. Tens of thousands of people have been killed in the insurgency, and hundreds of schoolgirls kidnapped, as the group gained notoriety and spread to neighboring countries, posing one of the most severe threats to West Africa's Sahel region in recent years. Although Nigeria has been a major partner in the U.S. fight against Islamist extremists in Africa, relations have faced challenges over the past year. In January, Nigeria joined a list of outraged African countries demanding an explanation from the U.S. ambassador after Trump's reported vulgar comments referring to African countries. Asked whether those comments came up during his private meeting with Trump, Buhari declined to comment. "I'm very careful with what the press says about other than myself. I'm not sure about, you know, the validity or whether that allegation was true or not. So, the best thing for me is to keep quiet," Buhari said.

Q: U.S. President-elect Donald Trump's choice to lead the Department of Homeland Security, retired Marine General John Kelly, is one of the U.S. military's longest-serving commanders and the most senior officer since 9/11 to lose a child in combat. Blunt-spoken and popular with military personnel, Kelly, 66, was born and raised in Boston. He initially enlisted in the U.S. Marine Corps in 1970, and was discharged from active duty as a sergeant in 1972. He returned to the Marine Corps after graduation from the University of Massachusetts Boston in 1976. Kelly rose through the ranks to serve as the commanding general of the Multi-National Force West in Iraq from February 2008 to February 2009, and as the commander of Marine Forces Reserve and Marine Forces North in October 2009. He succeeded General Douglas Fraser as commander of U.S. Southern Command (USSOUTHCOM) on Nov. 19, 2012. As the head of USSOUTHCOM, Kelly was in charge of the military jail at Guantanamo Bay, Cuba, and also was exposed to immigration, drug trafficking and other cross-border problems over a sprawling area that encompasses 32 countries in the Caribbean, Central America and South America. Kelly took a tough tone on border security, warning Congress last year about the risks of smuggling rings in Mexico and Central America that spirited "tens of thousands of people," including unaccompanied children, "to our nation's doorstep." He also clashed with the Obama administration over plans to close Guantanamo and the Pentagon's order that opened all jobs in combat units to women, including the most elite forces like the Navy SEALs. In 2010, Kelly became the highest ranking U.S. military officer to lose a child in combat operations in Southwest Asia. His youngest son, 1st Lieutenant Robert Michael Kelly, was killed in action in Afghanistan on Nov. 9, 2010. The younger Kelly was a Marine and was on his third combat tour, but on his first combat tour as a Marine Corps infantry officer. Since his son's death, Kelly has talked in stark terms about the...

In 1981, when I was nine years old, my father took me to see Raiders of the Lost Ark. Although I had to squint my eyes during some of the scary scenes, I loved it in particular because I was fairly sure that Harrison Ford's character was based on my dad. My father was a palaeontologist at the University of Chicago, and I'd gone on several field trips with him to the Rocky Mountains, where he seemed to transform into a rock-hammer-wielding superhero. That illusion was shattered some years later when I figured out what he actually did: far from spending his time climbing dangerous cliffs and digging up dinosaurs, Jack Sepkoski spent most of his career in front of a computer, building what would become the first comprehensive database on the fossil record of life. The analysis that he and his colleagues performed revealed new understandings of phenomena such as diversification and extinction, and changed the way that palaeontologists work. But he was about as different from Indiana Jones as you can get. The intertwining tales of my father and his discipline contain lessons for the current era of algorithmic analysis and artificial intelligence (AI), and points to the value-laden way in which we "see" data. My dad was part of a group of innovators in palaeontology who identified as "palaeobiologists" meaning that they approached their science not as a branch of geology, but rather as the study of the biology and evolution of past life. Since Charles Darwin's time, palaeontology especially the study of the marine invertebrates that make up most of the record involved descriptive tasks such as classifying or correlating fossils with layers of the Earth (known as stratigraphy). Some invertebrate palaeontologists studied evolution, too, but often these studies were regarded by evolutionary biologists and geneticists as little more than "stamp collecting".
