Newshour - Erdogan slams Israeli strikes as Muslim countries explore diplomatic options

At a gathering of Muslim-majority states in Istanbul, Turkish President Recep Tayyip Erdoğan has condemned Israel’s military strikes on Iran, accusing it of violating international law and risking “total disaster” in the region. Iran’s Foreign Minister Abbas Araghchi, also at the summit, warned that any US involvement in the conflict would be “very dangerous.” Also in the programme: In the UK, the launch of a new scheme to map the DNA of newborn babies; and 50 years after the hit film Jaws was released, we ask if it's finally time for a PR makeover for sharks.

Newshour - Iran-European talks debate Tehran’s nuclear programme

Iran agrees to a second day of talks in Geneva over the fate of its nuclear programme. Their meeting marked the first face-to-face dialogue between Tehran and western governments since Israel first attacked Iran a week ago. Also on the programme, witnesses say Israeli military kills 23 Palestinians near aid site in Gaza; and, 50 years since 'Jaws' became the first summer blockbuster.

CrowdScience - How can we persuade more people to cycle?

Cycling is good for our health, good for the planet, and it can be an efficient way of moving around busy cities. But despite all the rational arguments for it, in most cities the number of people who get on their bikes is low.

CrowdScience listener Hans wants to know whether it’s time to change our tactics. Could we persuade more people to cycle if we moved away from focusing on well-intentioned rational arguments and use messages that appeal to our desires and vanity instead? What does the science say? Presenter Caroline Steel is on the case.

She meets Winnie Sambu from World Bicycle Relief to learn about why people in countries like Kenya to choose the bike to get around. She heads out on a ride with psychologist Professor Ian Walker from the University of Swansea to find out what barriers there might be to persuading people to cycle.

She also takes a lesson from one of the world’s top cycling nations as she talks to Marie Kåstrup, a cycling campaigns expert who has advised the Danish government on inspiring cycling and sustaining it in the city of Copenhagen. Also in Denmark, Caroline meets behavioural scientist Dr Pelle Guldborg Hansen who shares his experience in the art of persuasion.

Focus on Africa - How different will the Rwanda-DRC peace deal be?

There is a glimmer of hope that three decades of conflict in the Democratic Republic of Congo could end after the government agreed a draft peace deal with Rwanda, a country accused of funding the M23, a group that has taken over some significant towns in the east of DRC. Representatives of the two countries will formally sign the agreement next week. But will this deal brokered by the United States work where others have failed?

Also, Egypt scrambles for gas supplies after Israel's oil refineries are struck by Iranian strikes and we examine whether other countries in Africa have been affected too.

And a bra-scandal: why female staff members at a university in Nigeria were touching the breasts of students before allowing them to take an exam.

Newshour - European ministers to hold talks with the Iranian foreign minister

UK, French and German foreign ministers will hold talks with their Iranian counterpart, Abbas Araghchi, in Geneva today as part of efforts to ease the Israel-Iran conflict.

Also on the programme: lawmakers in the UK hold a crucial vote on legalising assisted dying; and as Italian classical singer Andrea Bocelli releases a duet with the men's tennis world number one, Jannik Sinner, we'll ponder what draws some sports stars to dabble in music.

Unexpected Elements - Some really cool science

This week, the Florida Panthers beat the Edmonton Oilers at ice hockey’s Stanley Cup championship, which sent us skating into ice-related science.

First up, we hear about an ancient ice skate that’s been unearthed in Prerov, Czech Republic, which sends us pondering about the physics of ice-skating.

We then discover why licking a flagpole on a chilly day is a bad idea, before delving into the science of cryopreservation.

Next up, we speak to Dr Mark Drinkwater of the European Space Agency, who reveals how satellites can help us monitor and better understand our planet’s melting ice sheets.

Plus, what do you do if you want to play ice hockey but you live near the equator?

All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Chhavi Sachdev and Sandy Ong Producer: Alice Lipscombe-Southwell, with Margaret Sessa Hawkins and Minnie Harrop
