In 1965 a report from within the US government noted that the number of children born outside marriage, and the number of divorces, in the parts of the American population were rising rapidly. It argued that having many households run by a single woman risked holding back the progress of the next generation. At the time it was very controversial, rejected by mainstream academia and described as victim blaming. More than fifty years on, from the 'Moynihan' report we look at what modern research tells us about how children develop with married, cohabiting and single parents. Is there really a marked difference in their behaviour, cognition or emotional development?

Families from the Northern Triangle countries of Guatemala, Honduras and El Salvador now make up the majority of migrants arriving at the US southern border. Many from urban areas are fleeing endemic gang violence, while those from rural regions are affected by droughts and food security issues. The Mexican government is increasing security along their borders, while the Trump administration has been changing asylum law. Could these measures help to lower the number of people choosing to make the dangerous journey? Or is there another way to make sure migrants don't feel like they need to leave their homes?(Photo: A Guatamalan mother with her three daughters crossed Mexico to reach the US border city of Juarez-El paso, Texas.

Last month Hong Kong witnessed its largest ever protests, the most violent in decades. A proposed law to allow extradition of criminals to mainland China caused uproar. This bill exposed the cracks in relations between Hong Kong and the Beijing government. The current ‘one country, two systems’ arrangement gives the region some autonomy from Beijing. Pro-democracy protesters worry that this is being eroded as the Communist party is trying to bring it further under its influence. Complicating matters is Hong Kong’s significant but shrinking economic importance to China. With this year being the 30th anniversary of the Tiananmen square massacre the international community is nervously watching to see how modern China will respond to the civil disobedience on such a large scale.(Protesters storm the Legislative Council in Hong Kong on June 12, 2019.

With his unruly blond hair and shambolic appearance, Boris Johnson is Britain’s best-known politician. He’s also favourite to become the UK’s next Prime Minister. To his supporters, the former Mayor of London is charismatic, entertaining and a man of the people. His critics say he’s unprincipled, ruthless and flexible with the truth. If he wins the Conservative party leadership race, he’ll have to deliver Brexit. But what kind of leader might he be and how will he unite the country? Becky Milligan talks to some of those who’ve worked closely with him to find out what makes him tick.

South India’s biggest city, Chennai, is currently in the grip of drought. With the four main reservoirs which supply the city dry, residents have to queue for hours to collect pots of water from government tankers. Critics argue that the shortage isn’t just the result of a single failed monsoon season, but also the responsibility of the government who failed to plan for this scenario. Experts say 21 Indian cities could run out of groundwater next year, and that demand for drinkable water could outstrip supply by double in just a decade. So this week we ask, what can be done to solve this crisis?Image: Indian residents get water from a community well in Chennai Credit: Arun Sankar//AFP/Getty Images

Our species is facing a whole lot of problems. Antibiotic resistance is on the rise, land based minerals are depleting and there are serious concerns about how warm everything’s becoming.As the population grows these problems are only going to get worse, but what if we could find some of the solutions to our most pressing problems beneath the waves? Scientists have discovered that deep sea sponges could help fight MRSA, your smart phone could be powered by minerals located thousands of metres beneath the sea, and there are even enzymes that could help your washing machine run on a colder cycle, saving both energy and your new cashmere sweater. Is the deep sea the answer to some of our biggest problems? There’s a lot of promise, but what are the risks? Presenter: Ruth Alexander Producer: Lizzy McNeill(Photo: Sunset over the sea.

New Zealand is the first western country to state it should be judged not by its economic prosperity but by its citizens’ wellbeing. Might these wellbeing policies be masking an inability by governments to effect any real change in citizen’s lives or do they actually end up making economic sense after all?(Photo: New Zealand Prime Minister Jacinda Ardern.

The Democratic Republic of the Congo is in the midst of an Ebola epidemic, with over 2,000 cases now confirmed. In June the virus spread to neighbouring Uganda. Amidst this bleak picture, there is some hope; past epidemics have helped progress medical responses. This week, we ask: can vaccines contain Ebola in the DRC?Image: A health worker wearing Ebola protection gear, Beni, DRC Credit: Reuters.

Alabama has long been the butt of jokes in America. The stereotype is that it is backward, racist and right wing. This month the state passed one of the most restrictive laws on reproductive rights in the USA, banning abortion, even in cases of rape and incest. But it is not alone - many other states have similarly restrictive abortion laws but they do not get the attention that Alabama does. So why is it Alabama that always gets picked on?(Photo: Selma to Montgomery, USA historic street road sign in capital Alabama city. Credit: Getty Images)

Ever wanted to meet your historical heroes or explore the inventions of the future? Travelling in time has long been a dream of writers and filmmakers, but what does science tell us about how possible this would be to achieve in real life? We explore how physics shows us that time runs at different rates depending on where we are and how we’re moving - time goes more slowly for astronauts on the international space station for example. We hear about the very dangerous ways we could possibly exploit this to skip forwards through time and into Earth’s future, and we do the maths on wormholes, to see if they offer a possible portal to our past.
