Science journalist Rachel Cernansky joins host Sarah Crespi to talk about progress on Africa’s Great Green Wall project and the important difference between planting and growing a tree.
Sarah also talks with Václav Kuna, a postdoctoral researcher at the Institute of Geophysics of the Czech Academy of Sciences, about using loud and long songs from fin whales to image structures under the ocean floor.
The humpback whale is a species of baleen whale. It is one of the larger rorqual species, with adults ranging in length from 12–16 m and weighing around 25–30 t. The humpback has a distinctive body shape, with long pectoral fins and a knobbly head.
Despite recovering from an initial COVID-19 infection, many patients are experiencing severe symptoms months later. We find out about the impact of ‘Long Covid’ and the research that’s being done to try and understand it. News Feature: The lasting misery of coronavirus long-haulers
Radiation-detectors known as bolometers are vital instruments in many fields of science. This week, two groups of researchers have harnessed graphene to make super sensitive bolometers that could be used to improve quantum computers, or detect subtle traces of molecules on other planets.

27:49 Briefing Chat
We discuss some of the latest stories highlighted in the Nature Briefing. This week we chat about the lack of diversity in academia, and an animal ally that can protect wildlife during forest fires. Nature Careers: Diversity in science: next steps for research group leaders; National Geographic:
Didier Noirot is known as one of the world’s greatest underwater cameramen and has several prestigious awards for his natural history film camerawork. Over the past 40 years, Didier has been driven by his passion for marine life, but now he’s set himself a new challenge, to film what is perhaps the largest known gathering of marine mammals in the world; hundreds of killer whales in pursuit of shoals of herring. Today, these killer whales are faced with unexpected competition from humpback whales, who began appearing in this Arctic region only a few years ago, driven by a lack of food resources in the Atlantic Ocean, their natural habitat. In the midst of this changing ecosystem, we journey to the heart of the Norwegian fjords, where Didier Noirot’s aim is to take us as close as we can get to these giants of the Arctic so we can witness first-hand their new behaviour and hunting activity, which has never been captured on film before.
“Under Thin Ice”. World Premiere at the 2020 WCFF. Natalie Dubois, Producer and Denis Blaquiere, Director.
SYNOPSIS The Arctic is a majestic world, home to wildlife rarely seen in the south: bowhead whales, polar bears, narwhals, walrus, seals, zooplankton, algae. At the end of each spring, after long months of darkness, the sun shines for 24 hours a day and all living species gather at the floe edge — where ice meets open ocean — for a feeding frenzy. But global warming is threatening this ecosystem. Temperatures are rising and the ice sheet is melting at an alarming rate. In the last 40 years, more than 75% of the summer ice cover has disappeared.
Diving with whales, walruses and polar bears, Jill and Mario bring viewers into a majestic underwater world trying to adapt to ice loss and climate change. Viewers will travel on ice floes with Jill and Mario to Tallurutiup Imanga (also known as Lancaster Sound) in Nunavut, Canada, where they will dive with belugas and narwhals in the open Arctic Ocean. They will follow them to Greenland’s Disko Bay to explore the underside of icebergs and discover the luminescent world of algae. Back to Canada in the Naujaat region, they will swim with walruses and polar bears, the supreme predators of the Arctic. Filmed in stunning 4K, Under Thin Ice brings viewers into an awe-inspiring underwater world threatened by melting ice and rapid climate change.
The WCFF mission is to inform, engage and inspire wildlife conservation through the power of film and media.
The 10th annual WCFF in New York, NY will be a virtual event October 1-31. This is due to COVID-19 restrictions. New York State and the City of New York have not allowed movie theaters to reopen. Each day of the virtual festival will have LiveChats where the audience can interact with filmmakers, conservationists and scientists.
This week, researchers make diamonds tough, and evidence of incest in a 5,000 year old tomb.

00:51 Tough versus hard
Diamonds are famed for their hardness, but they are not so resistant to fracture. Now, researchers have toughened up diamonds, which could open up new industrial applications. Research Article: Yue et al.
