The effects of the Tonga eruption could be felt around the world, many heard the boom of a sonic shock, and tsunami waves travelled far and wide. Volcanologist Shane Cronin from the University of Auckland in New Zealand is one of only a handful of people to have landed on the tiny islands above the volcano where the eruption took place. Those islands have now sunk beneath the waves but Shane tells us what he found when he went there and how his findings could inform what happens next.
Stephan Grilli from the School of Ocean Engineering at the University of Rhode Island joins us from Toulon in France where he felt the effects of the shockwave and Tsunami. He says the force of the shockwave drove those waves worldwide.
The oceans have continued to warm, producing continuous record temperature rises for several years now. That’s the finding of Michael Mann of the University of Pennsylvania and author of The New Climate Wars. He says warming occurred last year despite the presence of global weather patterns which would usually have a cooling effect.
The long-term effects of covid-19 on health are a cause of growing concern even though in many places the virus itself now appears to be taking on a milder form. Yale University neuroscientist Serena Spudich is particularly concerned with covid’s impact on the brain. She says while the SARS- CoV-2 virus might not be found in brain cells themselves there are neurological impacts.
Many people are feared dead after a huge explosion near a mining town in western Ghana. Police say a vehicle carrying mining explosives collided with a motorcycle near the town of Bogoso. Liberia's President George Weah has declared three days of mourning following the death of 29 people in a stampede during a church service held on a football field in the capital, Monrovia.
President Cyril Ramaphosa of South Africa opens a brand new Covid vaccine plant in Cape Town, which could be a game-changer in the fight against the pandemic.
Meanwhile, Cameroon's plan to get people vaccinated using their love of football isn't going too well.
Also: an MP from Somaliland argues against independence from Somalia.

S2 Ep 30. Smart phones could become even smarter – thanks to ants, beetles, moths and spiders! A multi-animal special episode, marking the season 2 finale.
Patrick explores what could be an insect inspired phone of the future! There’s the story of the fire ants and bark beetles and a new camera lens with a much greater field of view. The hairs on butterflies, moths and spiders could help with an amazing new microphone. Moths might make it easier to look at our phones in bright sunlight. There’s also a waterproof, anti-bacterial cover which could be based on the wings of cicadas.

Studies using swabs from coronavirus patients seem to contradict earlier findings from cell cultures which showed Omicon replicated faster than earlier variants. As Benjamin Meyer from the centre for Vaccinology at the University of Geneva, explains there may be other reasons why omicron is spreading faster not just how quickly it reproduces.
Predicting how the pandemic will develop is not possible, however predicting what individual mutations in the virus may develop and the impact they might have individually and collectively is getting closer,
Cyrus Maher and Amalio Telenti of the biotech company Vir, have developed a way to model potential future viral mutations which they hope will now be used by many scientists worldwide looking to understand the virus.
There are concerns that other viruses may be on the rise, bird flu in particular, which as Nicola Lewis of the Royal Veterinary College explains is now spreading to part of the world where it is not usually seen, and infecting other animals as well as birds.
And we’ve news of a massive collection of nests – at the bottom of the sea, Deep sea Ecologist Autun Perser describes how he found them in Antarctica.
Also, Are big heads smarter? We live in a world where bigger is often seen as better - and the size of someone's brain is no exception. But a listener in Nairobi wants to know, does size really matter when it comes to grey matter? CrowdScience presenter Marnie Chesterton is on a mission to find out if the physical attributes of our head and brain can tell us anything about what's going on inside. We certainly thought so in the past.
In the 1800s, phrenology – determining someone’s characteristics by their skull shape – was very fashionable and curator Malcolm MacCallum gives us a tour of the extensive phrenological collection of death masks and skulls in Edinburgh’s anatomy museum. It's a 'science' that's now been completely debunked. Yet there’s no escaping the fact that over our evolutionary history, human brain size has increased dramatically alongside our cognitive capabilities.
But is it the whole story? Rick Potts, Director of the Human Origins Program at the Smithsonian tells of the point in time when human brains expanded the most; a time when the climate was changing, resources were unreliable and the intelligence to be adaptable might mean the difference between life and death. Adaptability is also key to Professor Wendy Johnson’s definition of intelligence, although she points out that IQ test, flawed as they are, are still the best predictor we have for intelligence… and that, yes, there is a weak correlation between having a larger head, and doing better at IQ tests. Why is that? We don’t know, says Dr Stuart Ritchie from KCL. According to him, neuroscientists are only in the foothills of understanding how a physical difference in the brain might underpin a person’s psychology. But researching this could offer valuable insights into how our amazing brains work.

Now being produced in India CORBEVAX is grown in yeast in a similar way to several other widely available vaccines. The technology used to make it is far simpler and much more readily available than that used to produce mRNA vaccines. In theory, CORBEVAX could be produced cheaply in large quantities and go a long way to addressing the problems of Covid19 vaccine availability globally. It was developed by a team from Baylor College of Medicine in Texas including Maria Elena Bottazzi.
Antibiotic-resistant superbugs are thought to have emerged in repose to the use of antibiotics, however, the discovery of a superbug living on the skin of hedgehogs has challenged this view. The superbug is thought to have been living with hedgehogs long before antibiotics were discovered. Jesper and Anders Larsen at the Danish State Serum Institute in Copenhagen explain.
Modifying viruses, using them to infect or kill pest organisms is an attractive proposition. However, there are concerns over what might happen when they are released, particularly over their ability to mutate and evolve says Filippa Lentzos from Kings College Department of Global Health and Social Medicine in London.
And The Royal Botanical Gardens at Kew have released the names of over 200 new species of plants and fungi discovered last year. Mycologist Tuula Niskanen and botanist Martin Cheek tell us more.
Also... “I’m bored!” We can all relate to the uncomfortable - and at times unbearable - feeling of boredom. But what is it? Why does it happen? And could this frustrating, thumb-twiddling experience actually serve some evolutionary purpose? CrowdScience listener Brian started wondering this over a particularly uninspiring bowl of washing up, and it’s ended with Marnie Chesterton going on a blessedly un-boring tour through the science and psychology of tedium. She finds out why some people are more affected than others, why boredom is the key to discovery and innovation, and how we can all start improving our lives by embracing those mind-numbing moments.
