The Santa Ana in the south, and the Diablo in the north, are winds that are fuelling the terrible fires raging in California this week. They\\u2019re also blamed for bringing down power lines that sometimes start the fires. Roland Pease talks to Janice Coen of the National Center for Atmospheric Research NCAR who has been developing a highly detailed model to forecast how wind, mountains, and flames interact during a wildfire. The glaring gaps in human genetics are in Africa \\u2013 much overlooked because the companies and universities sequencing DNA are mostly based in Europe, the US and other advanced economies. A ten-year attempt to fill in some of those gaps came to fruition this week, with the release of a study covering thousands of individuals from rural Uganda. Deepti Gurdasani, of Queen Mary University London, explains the data reveal both new medical stories, and the scale of past migration within Africa. There are also gaps in the climate record from Africa. Knowing past climates could help massively in understanding the prospects for climate change in coming years on the continent. Journalist Linda Nordling has just published an article in Nature that shows that the records exist \\u2013 old weather data collected since the 19th Century. It\\u2019s just they\\u2019re scattered, unexamined, in vaults and collections across Africa.

Most of us take the ability to speak fluently for granted but for listener Breeda it has been a lifelong struggle.

Breeda is not alone as stammering is a neurological condition that affects 70 million people worldwide.\\n \\n(Image: A firefighter sets a back fire along a hillside during firefighting operations to battle the Kincade Fire in Healdsburg, California.
