Dinosaur Auction
The Science Hour BBC
access_time4 months ago
This week an auction of a 70% complete dinosaur skeleton took place in Paris. The Therapod species, dating from the late Jurassic period about 155m years ago is scientifically very interesting. It’s an unknown predator which, argues the Society of Vertebrate Palaeontologists, is why it should not be owned by the highest bidder, but made available to palaeontologists for more scientific study. Roland Pease reports. Cancer Test If a doctor suspects cancer is behind a patient’s symptoms, blood tests and scans can help to detect tumours. Tiny bits of tissue can also be extracted in biopsies to see how advanced the disease is. Detecting cancer early offers a better chance of a cure. So news of a potential blood test to detect ten different types has been welcomed this week. Claudia Hammond spoke to Jacqui Shaw, Professor of Translational Cancer Genetics at Leicester University in the UK. Atlantic Hurricanes The 1st of June marks the start of the 2018 Atlantic hurricane season. Leading climate scientists debate whether we will see fewer or more tropical cyclones in the Atlantic as a consequence of anthropogenic climate change. There is a mounting consensus, however, that we will see more intense hurricanes. So do we need to add a more severe Category 6 to the Saffir-Simpson hurricane intensity scale? Roland Pease put this to climate scientist Michael Mann from Penn State University. Cancer Immunotherapy Treatment Immunotherapies for cancer have been in the news in the last week. Adam Rutherford talks to cancer researchers Sophie Papa of Kings College, London and Samra Turaljik of the Royal Marsden Hospital about the principles behind immunotherapy about the different approaches in the clinic and under clinical trials. Kenya Food App Getting access to loans in Kenya for small retailers can be tricky, but now cryptocurrency could solve this problem. Twiga Foods already provides marketplaces via an online platform for farmers and urban retailers. Now it is branching out to provide micro-loans secured via blockchain technology. CEO of Twiga Grant Brooke explains more to Gareth Mitchell. The Science Of Disgust Encouraging people to be healthier can involve gentle persuasion or giving some kind of incentive. Harnessing the most visceral of emotions – disgust – might not seem an obvious approach. Professor Val Curtis from the London School of Hygiene and Tropical Medicine has carried out an online survey in order to categorise the commonest types of disgust in order to harness its effects to fight against the spread of disease. She spoke to Claudia Hammond. The Science Hour was presented by Marnie Chesterton with comments from Kerri Smith, Nature features editor.

What’s the Tiniest Dinosaur?
Discovery BBC
access_time5 months ago
Two small creatures are at the heart of today’s questions, sent in to curiouscases@bbc.co.uk. The Tiniest Dinosaur "What is the tiniest dinosaur?" asks young listener Ellie Cook, aged 11. Our hunt takes us from the discovery of dinosaurs right up to the present day, which is being hailed as a 'golden age' for palaeontology. Currently, one new species of dinosaur is unearthed on average every single week. But what's the smallest dino? And what can size reveal about the life of extinct animals? Hannah Fry goes underground at the Natural History Museum in London to look through their vaults in search of the tiniest dinosaur with palaeontologist Susie Maidment. Meanwhile Adam Rutherford chats to dinosaur expert Steve Brusatte from Edinburgh University about why size really does matter, especially when it comes to fossils. The Baffled Bat "Why don't thousands of bats in a cave get confused? How do they differentiate their own location echoes from those of other bats?" This puzzling problem was sent in by Tim Beard from Hamburg in Germany. Since eco-location was first discovered, this question has perplexed biologists. Hannah turns bat detective to try and track down these elusive creatures at The Queen Elizabeth Olympic Park in East London. This is where zoologist Kate Jones from University College London is using a network of smart sensors to find, identify and track wild bats. Bat researcher and impressionist John Ratcliffe from Toronto University explains how bats use sonar to find their way around, and the clever tricks they’ve developed along the way. It's an unlikely tale involving gruesome early experiments, cunning electric fish and some surprising bat maths. (Image: Dinosaurs and a meteor falling from the sky in back background.

When the New Horizons space probe flew past Pluto three years ago, it revealed an expectedly exotic little world. The latest revelation from the data is that dunes creep across its surface. But as John Spencer of the South West Research Institute explains, these dunes are not made of sand grain, but tiny particles of frozen methane. Then again, it is minus 240 degrees Celsius on Pluto. Plenty, a Silicon Valley company plans to revolutionize farming by bringing it indoors and dramatically reducing water use. It has ambitious plans to replicate its warehouse farms in Japan, China and across Europe. Alison van Diggelen explores: the veracity of its technology; its environmental claims; its use of AI and automation; and how it plans to disrupt the agricultural industry. India is tackling an outbreak of the deadly Nipah virus. It has claimed at least 13 lives so far in the southern state, Kerala. The WHO has Nipah on its list as one of eight diseases that could cause a global epidemic. 40% of adults report that they have trouble falling asleep at least a couple of times a month. Common worries about the day’s events and what lies ahead can result in restlessness and low sleep quality. A new study shows that writing a to-do list before bed may help you to nod off faster A 10 kilometre wide asteroid wiped out 75% of life (including the dinosaurs) 66 million years ago. So it’s been a shock to discover this week that life rapidly returned, flourished and diversified at very place where the asteroid crashed into the Earth. Sean Gulick and Chris Lowery of the University of Texas in Austin talks about their discoveries and how they relate to today’s mass extinction crisis. Is Fasting Healthy? Marnie Chestherton cuts down on cookies and investigates the science behind low-calorie or time-restricted eating. She hears how some cells regenerate when we're deprived of food, which one researcher says could reduce breast cancer rates. The coldest place in the universe will be created shortly on the International Space Station. This will be in a box called the Cold Atom Lab installed on the station earlier this week. Lasers and magnets will cool a strange cloud of atoms to within a few fractions of a billionth of a degree above absolute zero. The Lab’s creator is physicist Rob Thompson of Nasa’s JPL in Pasadena.

Can Anything Travel Faster Than Light?
Discovery BBC
access_time5 months ago
Two astronomical questions today sent in to curiouscases@bbc.co.uk for Drs Hannah Fry and Adam Rutherford to answer. The Cosmic Speed Limit "We often read that the fastest thing in the Universe is the speed of light. Why do we have this limitation and can anything possibly be faster?" asks Ali Alshareef from Qatif from Saudia Arabia. The team grapples with Einstein's Special Theory of Relativity, with help from cosmologist Andrew Pontzen and a British train, travelling somewhat slower than the speed of light. Plus physicist and presenter Jim Al-Khalili describes how he nearly lost his boxer shorts in a daring bet concerning the speed of subatomic particles. The Cosmic Egg "How do we measure the age of the Universe?" asks Simon Whitehead. A hundred years ago this wouldn't even have been considered a valid question, because we didn't think the Universe had a beginning at all. Even Einstein thought that space was eternal and unchanging. This is the tale of how we discovered that the Universe had a beginning, and why calculating its age has been one of the greatest challenges in modern astronomy. We also uncover the mysterious dark energy that pervades the cosmos and discover why it's been putting a scientific spanner in the works. Helping to unravel today's question are physicists Andrew Pontzen, Jo Dunkley and Jim Al-Khalili.

GDPR Legislation to greater protect individuals’ data in the EU has come into force. What does it mean, and will there be unexpected consequences for the use of metadata? Gareth Mitchell talks to Claire Bury from the EU commission and Luukas Ilves, Deputy Director at The Lisbon Council. Polio Vaccination As vaccinations start in the Democratic Republic of Congo to try to contain the ebola outbreak, scientists in the United States have published research which they hope will help to simplify immunisations against diseases like polio. Eradication is tricky because the vaccine needs to be given in multiple doses. However, researchers at MIT say they have successfully vaccinated animals with just one injection. Claudia Hammond speaks to researcher Ana Jaklenec. Feel Good Garden Claudia Hammond visits the RHS Feel Good Garden at the Chelsea Flower Show. The garden is part of the 70th birthday celebrations for the NHS and was proposed by occupational therapist Andrew Kingston and designed by Matt Keightley to highlight the benefits of gardening for mental health. African Bee Parasites The presence of queen bees in a hive prevents them from being taking over by ‘parasite’ bees, a new study has found. Fiona Mumoki of the University of Pretoria explains to Roland Pease how the parasitic bees take over queenless hives, eventually causing hive collapse, and how the presence of a queen can enable hive fight back against the parasites. Drone Dog Rescue An engineer in India repurposed a drone to rescue a puppy that had fallen into a gully in New Delhi. Milind Raj constructed a giant claw that was attached to the drone. Raj says it took him six hours to assemble the improvised aerial vehicle.

Threat to conservation A third of protected nature reserves around the world are under threat from intense human activities like road building, grazing of animals and urbanization, according to a new study. Professor James Watson from the World Conservation Society explains to Roland Pease how only 10% of lands were completely free of human activity. Drones reforesting Myanmar Irina Fedorenko, Co-Founder of BioCarbon Engineering in Oxford, has been using drone technology to reforest the coastal areas of Myanmar. She tells Gareth Mitchell how they can restore natural ecosystems in a fraction of the time it takes traditional methods. Bitcoin energy Alex de Vries from accountancy group PwC explains how Bitcoin works, and how there is a limit to Bitcoin production. He speaks to Roland Pease about how his calculations suggest that Bitcoin electricity usage will soon be almost the same as the consumption of Ireland. Ebola outbreak in DR Congo The Ebola outbreak in DR Congo has spread from the countryside into a city, prompting fears that the disease will be increasingly hard to control. Health Minister Oly Ilunga Kalenga confirmed a case in Mbandaka, a city of a million about 130km (80 miles) from where the first cases were confirmed. Earlier this week, Claudia Hammond spoke to Helen Branswell from the US health website STAT about the action needed to prevent the spread of the disease. Alzheimer's disease We hear about efforts in Italy to help diagnose dementia earlier using computer algorithms to rapidly analyse thousands of brain scans for markers of the disease before symptoms become apparent. Agnese Abrusci reports from Bari in Italy. Evolution of music How have the trends in music changed over recent years? Natalia Komarova has tapped into databases online to discover what characteristics make a song ‘successful’. Her study, which uses machine learning to try to predict the success of songs, shows that the ‘happiness’ of songs is slowly declining, while the ‘danceability’ has increased. Roland Pease spoke to Dr Natalia Komarova from the University of California, Irvine. Picture: Madidi National Park, Bolivia.

Can We Use Chemistry to Bake the Perfect Cake?
Discovery BBC
access_time5 months ago
Domestic science is on the agenda today, with two culinary questions sent in by listeners to curiouscases@bbc.co.uk The Curious Cake-Off Can chemistry help us bake the perfect cake? Listener Helena McGinty aged 69 from Malaga in Spain asks, "'I have always used my mother's sponge cake recipe. But is there a noticeable difference in the outcome if you vary some of the ingredients, or the method?" Hannah and Adam go head to head in a competition to create the perfect cake using the power of science. They are aided by materials scientist Mark Miodownik, from University College London, with tips on how to combine the ideal ingredients and trusted techniques to construct a structurally sound sponge. Food critic Jay Rayner is on hand to judge the results. But who will emerge victorious in this messy baking battle? The Atomic Blade "What makes things sharp? Why are thinner knives sharper? What happens on the molecular level when you cut something?" All these questions came from Joshua Schwartz in New York City. The ability to create sharp tools allowed us to fashion clothing, make shelters and hunt for food, all essential for the development of human civilisation. And, more importantly today they allow us to prepare dinner. So what makes kitchen knives sharp? We hear from IBM scientist Chris Lutz, who has used one of the sharpest blades in the world to slice up individual atoms. Plus palaeoarchaeologist Becky Wragg Sykes reveals the sharpest natural object in the world, a volcanic glass used by the Aztecs called ‘obsidian’.

On the remote island of South Georgia, Antarctica, the invasion of rats from passing ships has wreaked havoc on the local wildlife. But the South Georgia Heritage Trust announced this week that all rats have been eradicated, thanks to an extensive project. Adam Rutherford speaks to chairman Professor Mike Richardson about the achievement and how wildlife is already healing. Amphibian Deadly Fungus According to new research a deadly fungus which has infected more than 700 species of amphibians originated from the Korean Peninsula. The data provides a more complete picture of how the fungus spread from region to region, and emphasises that human trade of amphibian species over the past 100 years has accelerated the spread of the disease. Simon O’Hanlon, from Imperial College London’s Department of Infectious Disease Epidemiology, explains more to Roland Pease. The Health Risks of Burning Waste in Lebanon Since the closure of a landfill site near Beirut, residents have started to burn rubbish which was building up on the streets. The Mount Lebanon region saw a 500% rise of cases of open burning. Respiratory doctors say the toxic fumes from the fires can put people’s health at risk, as Hugo Goodridge reports. The Smear Test The smear test – or pap smear – is carried out to detect any changes in cells which might later on lead to cervical cancer. But for some women the test itself puts them off going – as it can be uncomfortable and embarrassing. In the UK the number of women going for screening is at its lowest rate for 19 years and for 30 in the US. The design of the vaginal speculum used today dates back to the Ancient Greeks – so could it do with a re-design, to make it more patient-friendly? Claudia Hammond talks to Kate Sanger from Jo’s Cervical Cancer Trust and mechanical engineer, Fran Wong, from Frog Design in California. The Rise of the Dinosaurs We all know how dinosaurs became extinct, but how did they rise to prominence? Dr Steve Brusatte talks to Adam Rutherford about what the origins of dinosaurs and how they came to dominate the earth. Time in a Sauna Linked to Lower Stroke Risk For Finnish people there is nothing more relaxing than sitting inside a hot sauna. And now a new study suggests that taking frequent saunas could reduce the risk of having a stroke. The researchers believe that the intense heat helps to reduce blood pressure, cutting the risk. Claudia Hammond speaks to Dr Setor Kunutsor from the University of Bristol’s Musculoskeletal Research Unit.
