8:10 Dr Chris Smith: how exciting is Pfizer's vaccine news?

News that a collaboration between Pfizer and BioNTech has produced an effective coronavirus vaccine sent world stockmarkets soaring this week.

Pfizer said early results suggest the vaccine is more than 90 percent effective in preventing the disease among trial volunteers who had not previously been infected.

With no safety concerns as yet, the results have been described as "stunning".

So is this the breakthrough we have all been waiting for? And can people now start thinking about booking that overseas trip in mid-2021?

We'll ask our regular guest, Dr Chris Smith, consultant clinical virologist at Cambridge University, and one of BBC Radio 5 Live's Naked Scientists what he makes of the news.

8:30 Tim Harford: How to Make the World Add Up

COVID-19 has put the power and accuracy of statistics at centre stage. Infection rates, 'R' numbers, new cases, hospital admissions and the data underpinning new vaccines are being used by the media to tell stories about the pandemic, and are scrutinised daily to make vital public health decisions.

It is familiar territory for 'undercover economist', journalist and broadcaster Tim Harford who explores the beauty of statistics, and their uses, abuses and shortcomings in his new book How to Make the World Add Up.

The book is Harford's eighth following his bestseller The Undercover Economist, and the popular book (and BBC podcast) 50 Things that Made the Modern Economy.

For decades he's been studying one of the rarest and most publicity shy breeds of dog on the planet.

Now American zoologist and retired biology teacher James 'Mac' McIntyre has made his breakthrough discovery.

Through DNA tests conducted on animals trapped on a series of intrepid expeditions through Papua New Guinea and West Papua, he's managed to establish that the New Guinea Singing Dog- also known as the New Guinea Highland Wild Dog- still survives in the wild.

Until this discovery the breed was only thought to survive in a captive (and highly inbred) population scattered around the globe. Mac's the founder of the New Guinea Highland Wild Dog Foundation and has another highly specialised research interests: intersex pigs in Vanuatu.

Kathy Baughman McLeod is Director and Senior Vice President of the Adrienne Arsht-Rockefeller Foundation Resilience Center at the international affairs think tank, The Atlantic Council.

Working on the intersection between business and future environmental risk, her old job at Bank of America involved planning the investment of US$125 billion into eco friendly projects by 2025.

She also led a team at the Nature Conservancy using natural infrastructure (and tailored insurance policies) to reduce storm and flood risk in low lying economies through Latin America, Australia, Asia, the US, and the Caribbean.

An author and documentary producer, Baughman McLeod now wants us to start naming heat waves like hurricanes to highlight the impact of the world's changing climate.
