An outbreak of Lassa fever in Nigeria has made hundreds ill and killed at least 43 people. With symptoms including bleeding from gums, eyes and nose, it shares some similarities with Ebola, but is less infectious and can be mild. Claudia Hammond talks to Professor Dan Bausch of the UK Public Health Rapid Support Team, which is preparing to send people over to Nigeria, if required, to contain the outbreak.

The Beaker People
Around 4,500 years ago, 90% of the British population was replaced by incomers from Iberia, known as the Beaker people. Archaeologists had uncovered elements of the Beaker culture - stylised bell-shaped pots, copper daggers, arrowheads, stone wrist guards and distinctive perforated buttons - but were unsure whether this represented a wave of mass migration or a fashion trend spread across Europe through trade. This week, Professor David Reich published one of the largest ancient DNA studies ever, detailing how the Beaker people spread across Europe. Marnie Chesterton spoke to him.

Planet Formation
The annual meeting of the American Association for the Advancement of Science 鈥� held this year in Austin, Texas 鈥� concluded this week. On the agenda were topics that ranged from the difficulty of conveying the science of climate change to all those who need to know, to the growing impact of artificial intelligence, and the hunt for other planet Earths. Along those lines, a session that caught the eye of Roland Pease was the study of planets caught in gestation around newly formed stars. He spoke to Karin 脰berg, astronomer at the Harvard-Smithsonian Center for Astrophysics.

Water Crisis in Cape Town
9th July - it鈥檚 being called Day Zero, the day the water is turned off in drought stricken Cape Town in South Africa. After three years of unexpected dry weather leaving no water in the reservoirs that serve the city, Roland Pease speaks to water policy analyst Sandra Postel about what can be done to mitigate the water shortage and how to prevent the same thing happening in other cities.

The Healthy Habits Of 'Super-Agers'
Aging well is a topic most people have a personal interest in鈥攕cience certainly does. And it鈥檚 revealed some interesting findings in recent years, as long-term studies on 鈥渟uper agers鈥� from across the globe have come in. Bobbie Lakhera has been looking at the latest studies.

Masks Putting Children with Cancer at Ease
Cancer treatment is difficult for children to endure and for parents to watch. St James Hospital in Leeds in the north of England is helping its young patients to cope by painting the masks they have to wear to keep them still during radiotherapy. Paula McGrath went to meet some of the children and staff.

Hurricane Bells
A new collaboration between an artist and a cyclone physicist commences this week. Peter Shenai and Dr Carlo Corsaro have joined forces to model Hurricane Katrina and cast its shape into six brass bells. Each bell represents a key moment from the category 5 storm, as it progressed across the Gulf of Mexico and made landfall in the United States in 2005. Marnie Chesterton talks to them.
