Science In Action

AI is already being used in every branch of science, and will become more and more a feature of future breakthroughs. But with its power to find subtle patterns in massive data sets comes a concern about how we will know when to trust its outcomes, and how to rely on its predictions. Science in Action talks to Alison Noble who just completed a Royal Society report on trust in scientific AI.

Fentanyl is a powerful morphine substitute, but it is also incredibly addictive – millions struggle with weaning themselves off it. And of the 600,000 drug deaths worldwide each year, the World Health Organisation estimates 80% are due to opioids in general, with synthetic opioids like fentanyl being a growing part of the problem. New work with genetically manipulated mice suggests that fentanyl affects two parts of the brain, one ...

They were the best northern and southern lights in decades, but why? And what’s next? We hear from astrophysicist Steph Yardley about the solar maximum, geomagnetic storms and atmospheric spectaculars.

Also, the impossible heatwave in the Philippines made possible by global warming – the analysis of a continent-spanning climate extreme by the World Weather Attribution collaboration.

Could future blood transfusions be made safer by mixing in a new bacterial enzyme? Every year 118 million blood donations need to be carefully sorted to ensure the correct blood types go to the right patients. Prof Martin Olsson, of Lund University in Sweden, and colleagues in Denmark have published a study that suggests an enzyme made by bacteria in our gut could edit our blood cells to effectively convert type A, B and AB to type...

As bird flu is found in US farm cats fed on raw cow’s milk, chimpanzees are observed eating infected bat dung instead of vegetables. There is a constant threat of infections crossing from species to us and also from species to other species, particularly because of what we do. That is, after all, what happened to start the pandemic.

We hear about the ongoing struggles of the Chinese virologist who broke his instructions in China in ...

Friday, April 13th 2029 – mark it in your calendar. That’s the day an asteroid the size of an aircraft carrier will fly past Earth, closer than some satellites. Don’t worry – it will miss, but it’ll will pass so close to Earth that it will be visible to the naked eye of 2 billion people, particularly in North Africa and Western Europe.

A black hole just discovered in our Milky Way galaxy, weighing 33 times the mass of the Sun, and dating back to near the time of the Big Bang, gives new clues to the origins of this dark astronomical mysteries. And dancing with a Sun-like star in our galactic neighbourhood, it offers a great opportunity for astronomers to take a detailed look in coming years, as astronomer Professor Gerry Gilmore of Cambridge University tells the p...

The highly pathogenic strain of bird flu, H5N1, has arrived on the continent. Australian bird specialist Megan Dewar, from the Federation University of Australia, has led a mission aboard the research ship the Australis.

Science in Action remembers physicist Peter Higgs 60 years after his Nobel prize winning theory of the Higgs particle.

The unfolding scandal of manipulated data behind claims of incredible room-temperature superc...

A powerful earthquake hit Taiwan on Wednesday morning, but thanks to the country’s early warning system and engineering-preparedness, there was little destruction and few deaths. Seismologist Ross Stein, CEO of earthquake consultancy Temblor, Inc., shares his analysis. The highly pathogenic bird flu H5N1 has been detected in cattle in the US and in a cattle handler in Texas. To learn more about this special animal-to-human trans...

3000 light years from Earth, a white dwarf star called T Coronae Borealis is on the brink of a “once-in-a-lifetime” explosion. Astrophysicist Bradley Schaefer is enthusiastic about the bright star set to appear in the night sky in the coming months.

Professor Irving Weissman has been researching ways to restore youth using mouse models for decades. He has sewn old and young mice together to join their circulatory systems and has f...

The last great "out of Arica" movement of our ancestors swept out of the northeast of the continent 74,000 years ago. Archaeologist John Kappelman of the University of Texas brings us an update to this complex tale in the form of animal carcasses.

We take a trip to Oxford to meet some of postgraduate researcher Ally Morton-Hayward's archive of preserved brains. Not only is Ally shining a light on these underappreciated brains, she...

After a twelve-month set of climate records driven by global warming it is time to take stock of how we’re impacting the planet as a species.

Coral biologist Kate Quigley, of the Minderoo Foundation and James Cook University, dives into the 8th mass bleaching event at the Great Barrier Reef. We explore how deadly heat stress continues to threaten this underwater paradise and induce mass sickness in the corals that call it home. ...

Astronomers using the James Webb Space Telescope think they have seen the glow from the first generation of stars after the Big Bang. Newton Kavli Fellow Hannah Übler discusses.

The Anthropocene is meant to mean the latest geological era in which humanity is shaping the rocks and environment of our planet. But an unexpected vote by a commission has declined the idea of making this an official definition. Roland hears from one of it...

The All of Us Research Program is undergoing the herculean task of gathering genomic data from over one million people living in the United States, from widely different backgrounds, in the hopes of accelerating health care research. However, within the scientific community many, including Ewan Birney, deputy director general of the European Molecular Biology Laboratory, are concerned that the way some of this data has been framed ...

A monumental Covid vaccine safety study of 99 million vaccinated people confirms just how rare adverse effects are and combats growing vaccine misinformation. Co-director of the Global Vaccine Data Helen Network goes through the results of this massive study.

This week, Science in Action is bringing you not one, but two extraordinary astronomical discoveries. First, Webb Fellow Olivia Jones on the star hidden in the heart of only s...

High-profile climate scientist Michael Mann has been embroiled in a 12-year battle against conservative commentators who claimed his data was fraudulent. Last week, he was awarded $1m in a defamation lawsuit. Michael joins Science in Action to discuss the case and the impact it may have.

Also, this week, Karyn Rode from the US Geological Survey has been using cameras on collars to track polar bear movement and diet. She tells Rolan...

Should CERN be spending $17 billion on a new atom smasher whilst we face, climate change, the most pressing crisis of our time? Materials-turned environmental scientist Mark Miodownik and CERN physicist Kate Shaw debate the issue.

One of the issues Mark argues more people should be tackling are the climate change driven forest fires which recently ravaged Chile and killed more than 100 people. Chilean climate scientist Raul Corder...
