President Trump's envoy Steve Witkoff is in St Petersburg for talks with Vladimir Putin as the US pushes for a ceasefire in Ukraine. Meanwhile, China raises tariffs on American goods to 125%.
The Aurora Borealis – also known as the Northern Lights – won’t be at their peak activity much longer, and the Unexpected Elements team dreams of going north to see them. And that has got us looking at the science of navigating our way north!
We hear about how humans have been using the sky to navigate for millennia, and we learn about how relying on GPS may be impacting our memory ability.
And while humans use maps to get around, how do animals know where to go on their long migrations? To find the answer, we speak to Dr Kayla Goforth at Texas A&M University who studies exactly how sea turtles and monarch butterflies innately know how to navigate the world around them.
We also learn why polar bears keep themselves ice-free, and we hear old records of the first men to reach the North Pole.
All that, plus many more Unexpected Elements.

US President Donald Trump says transition to new trade world won't be easy, as markets process the White House’s 145% tariff rate for China. Also: Prada agrees to buy rival luxury fashion brand Versace.
Pain, particularly chronic pain, is hard to research. New therapeutics are hard to screen for. Patients are not all the same. Sergui Pascu and colleagues at Stanford university have been growing brain samples from stem cells. Then they began connecting different samples, specialised to represent different brain regions. This week they announce their most complex “assembloid” yet, one that even reacts to hot chilli, passing a signal from the sensory neurons through to the thinking bits. The hope is that it can provide insights on how pain, and potential painkillers, work.
Human brains are notoriously large, particularly infants. Whilst for primates the human pelvis is quite narrow, to allow us to walk and run on two legs. This notoriously makes childbirth, well, not as straightforward as most other species. This evolutionary “obstetric dilemma” has been debated for decades. Marianne Brasil, of Western Washington University, and colleagues, have published this week a huge study of contemporary human genes and anatomies available from the UK Biobank to shed some more light on this ongoing compromise.
Malta is an island in the Mediterranean no less than 80km from land. So how come Eleanor Scerri and colleagues have discovered archaeological evidence of hunter-gatherers living there from 8,500 years ago? And they didn’t just visit and leave. They stayed for perhaps a millennium before farming arrived. Maybe a rethink of what nautical capabilities our ancestors had in the deep past is needed?
A year ago, Science in Action gate-crashed a conference looking at plans for meeting the forthcoming arrival of asteroid Apophis in 2029. This year the meeting is in Tokyo, and Richard Binzel, emeritus professor of Astronomy at MIT, gives us an update on how the space agencies are hoping to collaborate to maximise the scientific value from what will be a global, visible, phenomenon in just 4 years. Is there enough time to get our collective wits together?
