Science: CNO Neutrinos At The Sun’s Core, Covid-19 & Contraception (Podcast)

Scientists have finally confirmed the existence of a CNO cycle fusion reaction in the Sun, and why women’s contraception research needs a reboot.

In this episode:

00:47 Detection of CNO neutrinos

Since the 1930s it has been theorised that stars have a specific fusion reaction known as the CNO cycle, but proof has been elusive. Now, a collaboration in Italy report detection of neutrinos that show that the CNO cycle exists.

21:50 Getting women’s contraception research unstuck

Since the 1960s there has been little progress on research into women’s contraceptives. This week in Nature, researchers argue that this needs to change.

Comment: Reboot contraceptives research — it has been stuck for decades

29:35 Briefing Chat

We discuss a highlight from the Nature Briefing. This time, a tool to summarise papers.

Video Trailer: ‘A Perfect Planet – BBC Earth’ With David Attenborough

A Perfect Planet is an awe-inspiring exploration of Earth’s power and fragility.

PERFECT PLANET

Planet Earth is perfect. It orbits at the perfect distance from the sun; it tilts at just the right angle and has a decent sized moon to hold it in place. On top of that, the day-to-day workings of the planet naturally serve to nurture animals and plants.

This five part series will show how the forces of nature – weather, ocean currents, solar energy and volcanoes – drive, shape and support Earth’s great diversity of life. In doing so, it will reveal how animals are perfectly adapted to whatever the environment throws at them.

Wildlife: ‘Return Of The Reds’ – Rewilding Red Squirrels Into Scotland

Red squirrels are receiving a helping hand in reclaiming lost ground. A partnership between Trees For Life and The Woodland Trust is returning red squirrels to Ledmore and Migdale woods in Sutherland.

Ecology: Wildfires Kindle Natural Biodiversity

Raging fires throughout the U.S. and Australia over the past year have put vulnerable species at risk. But not all blazes are devastating—in fact, fire can promote biodiversity. In grasslands, fires prevent trees and roots from taking hold. This allows grazing animals the space and vegetation they need to thrive. As the pattern of wildfires changes, a new review in Science outlines effective ways to let natural fires burn, while preventing out-of-control blazes. Watch to learn how a few of these techniques have been applied around the world.

Health & Nature: ‘How Bats Can Transmit Viruses’

When it comes to viruses jumping from animals to humans, bats hold a unique place in the transmission chain. Christopher Golden and James Longman investigate an abandoned mine for signs of poaching or viruses impacting the bat population.

Nature & Photography: ‘Wonderful Little Things’ By Christian Fleischer

Filmed and Edited by: Christian Fleischer

When chaos, stress and distraction comes over us, it is good to calm down and focus on the wonderful little things that mother nature is blessing us with.

So I like to invite you to have a break, relax and enjoy some meditative moments of witnessing the little creatures, plants and mushrooms down at your feet, which normally remain invisible for most of us most of the time.

Preservation: ‘Tree Of The Year 2020’ In England, Wales & Scotland (Video)

Scotland’s #TreeOfTheYear 2020 – The Survivor Tree, Carrifran Valley.

It was once a lone rowan clinging to a stream bank in Carrifran Valley, but today that survivor tree is lonely no more! It is surrounded by a little forest of its children, and lots of suckers are coming up from its base. This was some of the first natural regeneration the Borders Forest Trust achieved in the Carrifran Valley. In addition to its own children, the rowan tree now has over half a million other native Scottish trees for company. Where once it dominated the view, it will soon be hidden from sight. The rowan tree no longer stands alone and is a symbol of the 20-year journey to revive the wild heart of Southern Scotland.

Wales’ #TreeOfTheYear 2020 – The Chapter House Tree, Margam Park, Port Talbot.

Standing in the shadows of 17th century Margam Orangery and St Mary’s Church, this historic fern-leaved beech envelopes the remains of one of the first Cistercian abbeys in Wales. Its canopy has provided shelter to visitors for many years – from Victorian tea parties taking place under its sweeping boughs to a favourite summer picnic spot for present day visitors. The tree provides an atmospheric back drop and is loved by cinematographers – featuring in TV and Film productions from Dr Who and ‘Songs of Praise’ with Sir Bryn Terfel to the recent Netflix blockbuster series ‘Sex Education’.

England’s #TreeOfTheYear 2020 – The Happy Man Tree, Hackney, London. Currently earmarked for felling, the plight of this 150 year old Plane has awakened something in a community that couldn’t bear to see it go. The dressing of the tree, and the signs behind it, are testament to the strength of feeling among the local campaigning. As an urban tree, it makes an important contribution to combating air pollution and making grey city streets green. But the community sees it as more than just the sum of it’s parts – it’s part of the estate, part of their collective history.

Video Interviews: ‘Sir David Attenborough – A Life On Our Planet’ (PBS)

Filmmaker Sir David Attenborough has been documenting the natural world since the 1950s. In his latest book and film, “A Life on Our Planet,” he offers a grave and alarming assessment about the climate crisis Earth is facing. The 94-year-old Attenborough spoke with William Brangham recently as part of our ongoing arts and culture series, Canvas.
