Global sea levels are rising more than 3mm per year under current climate conditions. At this rate we are due to hit an alarming 7mm rise per year by the end of the century. If this is not slowed, it could lead to the drowning of essential coastal ecosystems like mangroves and lagoons, professor of environmental science Neil Saintilan tells Science in Action. The seas are also heating up. We’ve covered the devastating effect of marine heatwaves on vibrant sea life like coral reefs before. But what about the less glamourous bottom-dwelling fish? Ecologist Alexa Fredston has found that they may be more robust than we think. Also this week, bird virus expert Michelle Wille tells us about the imminent threat of bird flu spreading from South America to Antarctica where hundreds of thousands of sea birds are at risk. And from one south pole to another, we have an update on how India’s mission on the lunar south pole is going with Lunar and Planetary Institute scientist David Kring.

Advances in brain-computer interfaces have allowed patients with paralysis to communicate faster, more accurately and more expressively with direct brain to speech translation. Co-author of an exciting new paper in the field, bioengineer Alex Silva, tells Science in Action about his team’s work with patient Ann. The world has been following the Indian and Russian race to land on the lunar south pole. Producer Ella Hubber gives a timeline of the events leading up to that historic landing. Also this week, a new prediction model allows us to better prepare for future extreme weather events. But is this worst-case scenario model scaremongering? Roland talks to author Erich Fischer about the projections. And virologist Connor Bamford talks detecting bird flu in wastewater for betting monitoring.Image Credit: Noah BergerPresenter: Roland Pease Producer: Ella Hubber Editor: Richard Collings

Hawaii is still reeling from the devastating fires that consumed Lahaina on the island of Maui last week. Professor of Meteorology from the University of Hawaii, Kevin Hamiliton, joins Science in Action to discuss the factors that make these events more likely across the Hawaiian Islands. Amongst these is climate change. Also this week we discuss the concerning reports of a sudden spike in methane levels in the Arctic with Xin Lan of the US National Ocean and Atmospheric Administration. A few weeks ago, we devoted a whole programme to the exciting research on human embryo models made from stem cells. Whilst representing an incredible step for medical research, these raise serious ethical questions. A team of biologists and embryologists have put together a proposal on how to move forward with this ethical quandary, Embryologist Nicolas Rivron tells us more.And we address the incredible claim of the room temperature super conductor, LK-99, with sceptical materials scientist Michael Fuhrer.Photo: The Maui town of Lahaina after being destroyed by wildfires Credit: Getty ImagesPresenter: Roland Pease Producer: Ella Hubber Editor: Richard Collings

ProMED is one of the most useful scientific tools you’ve never heard of. It’s a global surveillance system of infectious disease outbreaks which is available, for free, to researchers and the public alike. But ISID, the society which runs the platform, claim they have run out of money to support ProMED and will be switching to a subscription service, against the wishes of both users and staff. ProMED editor Marjorie Pollak tells Science in Action about the vital service ProMED has played in pandemic monitoring – including the very first COVID outbreaks - and ISID boss Linda MacKinnon considers what’s next for the platform. From wildfires in Europe to droughts in Africa, we have covered every kind of environmental disaster across most of the globe in the space of the past few weeks. To complete the distressing bucket list of climate extremes, we’re talking to sea ice expert Caroline Holmes on the concerning forecast for Antarctica. Despite these terrestrial challenges, NASA is still trying to defend Earth against nearby objects which might hit us from space. The Double Asteroid Redirection Test (DART) was launched at the asteroid Dimorphos back in in November 2021 and, a few weeks ago, the Hubble space telescope observed a swarm of boulders shed by Dimorphos post-impact. Some UK newspapers are concerned about their trajectory, but astronomer Dave Jewitt is here to calm us all down.Photo: Disinfection Work At Wuhan Huanan Wholesale Seafood Market Credit: China News ServicePresenter: Roland Pease Producer: Ella Hubber Editor: Richard Collings

Science in Action returns to H5N1, the fast spreading strain of bird flu which has caused devastation in the sky, sea, and land over the last few months, with no end in sight. Roland visits Skomer Island and the coast of Wales where sea bird colonies are threatened and hundreds of guillemots have washed ashore dead, struck down by bird flu. We also hear of outbreaks on Finnish fur farms where controversial plans are in progress for culls of wild birds, of mysterious infections of domestic cats in Poland, and bird flu causing brain swelling in grey seals. Plus, we get an update on efforts to vaccinate condors in California against the disease.Photo: Dead Guillemot Credit: BBCPresenter: Roland Pease Producer: Ella Hubber

A large system of ocean currents known as the Atlantic meridional overturning circulation (AMOC) has been making headlines this week as a new paper predicts its imminent collapse. This could have devastating consequences for the climate. But not all climate scientist and oceanographers are convinced by the results. Stefan Rahmstorf and Eleanor Frajka-Williams debate the contentious paper.In more positive news, huge steps have been made in the field of gene therapy. Stefano Rivella and Hamideh Parhiz tell us about their incredible mRNA delivery technology which could take much of the cost and risk out of treating debilitating disordersAnd as wildfires continue to blaze around the world, reporter Melanie Brown discovers how experts study the physics of these blazes from the Missoula Fire Sciences Laboratory.

For the third year running, Iceland’s Reykjanes peninsula is experiencing another spectacular volcanic eruption. Volcanologist Evgenia Ilyinskaya has been out in Iceland witnessing the sight and getting samples of the noxious fumes. Across the rest of the Northern Hemisphere heat domes persist, bringing extreme weather ranging from wildfires to tornadoes. We keep on seeing that this year “is the warmest in 120,000 years”. But what does that mean? Two paleoclimatologists, Bette Otto-Bliesner and Jessica Tierney tell us more.And we’re going deep. Deep into the brain that is, with a newly-developed probe which is finer than a baby’s hair. Dr Anqi Zhang of Stanford University explains her delicate technology. Finally, new research suggests that SARS-CoV-2 could have arisen in the wild no more than four years ago, a mishmash of other viral genomes. Bioinformatician Jonathan Pekar discusses his new paper.Presenter: Roland Pease Producer: Ella Hubber Editor: Richard Collings(Photo: Dr. Evgenia Ilyinskaya Credit: @EIlyinskaya)

As extreme heat returns to much of the world we hear the impact of last year’s heatwaves in Europe, where 62,000 people are estimated to have died. Joan Ballester, Associate Research Professor at Barcelona Institute for Global Health, discusses the figures from his latest paper and his concerns for the future. This week the European Court of Human Rights ruled in favour of middle-distance runner and Olympic champion Caster Semenya in a case related to testosterone levels in female athletes. Marnie Chesterton speaks to developmental biologist Dr Emma Hilton about what causes differences in sexual development and the impact they can have.Also, Kew Gardens is going digital. Millions of specimens are being made available to the world for the first time in an enormous digitisation project. Ella Hubber goes behind the scenes at Kew to see some of the precious specimens. Finally, the Indonesian government has banned a group of foreign scientists from conducting conservation research. Bill Laurance, Research Professor at James Cook University, talks to Science in Action about keeping politics out of conservation science.Image credit: Getty ImagesPresenter: Roland Pease Producer: Ella Hubber

Record-breaking global temperatures are accelerating Greenland ice melt at an alarming rate. Professor of glaciology Alun Hubbard has witnessed the melt first hand. He tells us how the ice sheet is being destabilised and what this could mean on a human level. Also, how safe are Japanese plans to dispose of nuclear waste from the Fukushima accident? We get reassurance from molecular pathology expert, Professor Gerry Thomas. And last week was a big one for cosmology news. We catch up on science behind the gravitational hum that permeates the Universe with astrophysicist with Dr Chiara Mingarelli. And we hear about the traces of ghostly neutrinos within our Galaxy from the principal investigator of the world’s largest neutrino detector, Professor Francis Halzen.
