Orcas have a special way of hunting herring.
The killer whale or orca is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey.
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.
“Sunday Morning” takes us to Tahoe National Forest, northwest of Lake Tahoe, in California. Videographer: Derek Reich.
Tahoe National Forest is a United States National Forest located in California, northwest of Lake Tahoe. It includes the 8,587-foot peak of Sierra Buttes, near Sierra City, which has views of Mount Lassen and Mount Shasta. It is located in parts of six counties: Sierra, Placer, Nevada, Yuba, Plumas and El Dorado.
Researchers try to unpick the complex relationship between sensory pollutants and bird reproduction, and how to combat organized crime in fisheries.
In this episode:
00:46 Sensory pollution and bird reproduction
Light- and noise-pollution have been shown to affect the behaviour of birds. However, it’s been difficult to work out whether these behavioural changes have led to bird species thriving or declining. Now, researchers have assembled a massive dataset that can begin to give some answers. Research article: Senzaki et al.

Interim results from a phase III trial show compelling evidence that a coronavirus vaccine candidate can prevent COVID-19. However, amid the optimism there remain questions to be answered – we discuss these, and what the results might mean for other vaccines in development.

25:39 Organised crime in fisheries
When you think of fishing, organised crime probably isn’t the first thing that springs to mind. However, billions of dollars every year from the fishing industry are lost to criminal enterprises. We discuss some of the impacts and what can be done about it. Research Article: Witbooi et al.
32:13 Briefing Chat
We discuss some highlights from the Nature Briefing. This time, a time-capsule discovered on the Irish coast provides a damning indictment of Arctic warming, and some human remains challenge the idea of ‘man-the-hunter’.

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.

Astronomers pin down the likely origins of mysterious fast radio bursts, Covid-19 in schools, octopuses taste with touch and the latest on what the US election means for science.

00:46 The origins of mysterious fast radio bursts
The detection of a brief but enormously-powerful radio burst originating from within the Milky Way could help researchers answer one of astronomy’s biggest mysteries.

At the start of the pandemic, there were fears that schools could become hotspots for infections. We discuss the evidence suggesting that this is unlikely to be the case, and the rates of infection in children of different ages.

“Nature reveals itself to us in unique ways, if we stop and look at the world through a window of time,” says photographer Stephen Wilkes. Using a special photographic technique that reveals how a scene changes from day to night in a single image,
Wilkes exposes the Earth’s beautiful complexity and the impacts of climate change — from the disruption of flamingo migrations in Africa to the threat of melting ice — with unprecedented force. This performance was part of the Countdown Global Launch on 10.10.2020.

Countdown is TED’s global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world.
The “Cocoon Hotel & resort”, Tulum, Mexico– a new concept of eco-tourism, and a great opportunity of connection with Nature, Community, Ourselves, inspired by the sea and the exotic forest. The project consists of 46.181 m2 offering 3 residential and 2 hotel buildings “COCOON” with 204 apartments and 167 rooms as well as 16 private villas.Every feature serves to give a unique experience and create a magical place for the guest, at the same time making him identify what is Mexico.
The complex offers luxury community spaces integrated into nature such as jungle gardens, magical outdoor living spaces-villas, multipurpose pavilion, indoor community spaces, leisure areas, restaurant, and a panoramic Nest with unrestricted and breath-taking views. All to achieve a wide vocabulary of visual elements to mutate into designing language, in materials and shapes, for a bio-mimicry architecture.
The idea was to create “Cenotes”- natural freshwater ponds, to which the Mayans gave a sacred use, thus allowing to experience the real Mayan´s rituals. The project makes an emphasis on sustainability concept respecting ecosystem and biodiversity, contributing to the usage of natural materials that minimizes the impact of building and generation of waste. The water collection concept is also respected and represents a recovery of rainwater for sewage treatment. The solar panels are implemented to achieve sustainable electricity.
Finally, the “dry” construction system is used, meaning no wet binders, shorter execution time, and increased safety and sustainability. Source by dna Barcelona.

The chances of mini brains becoming sentient, herd immunity, bat-like dinosaurs, and a UK government decision threatens gender diversity in academia.
In this episode:
00:59 The ethics of creating consciousness
Brain organoids, created by culturing stem cells in a petri dish, are a mainstay of neuroscience research. But as these mini-brains become more complex, is there the chance they could become conscious, and if so, how could we tell?

So called ‘herd immunity’ is claimed by some as a way to break the chain of infection and curtail the pandemic. However epidemiologists say that this course of action is ineffective and will lead to large numbers of infections and deaths.

23:22 How cutting red-tape could harm gender diversity in UK academia
The Athena SWAN scheme, designed to boost gender-equality in UK academia, has proved effective, and has been exported to countries around the world. But now a decision by the UK government to cut bureaucracy could mean that institutions pay less heed to schemes like this and threaten future efforts to increase gender diversity in UK academia.
Editorial: Equality and diversity efforts do not ‘burden’ research — no matter what the UK government says

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.
