The 'ghost roads' driving tropical deforestation
In this episode:00:46 Mapping ‘ghost roads’ in tropical forestsAcross the world, huge numbers of illegal roads have been cut into forests. However, due to their illicit nature, the exact numbers of these roads and their impacts on ecosystems is poorly understood. To address this, researchers have undertaken a huge mapping exercise across the tropical Asia-Pacific region. Their findings reveal over a million kilometers of roads that don’t appear on official maps, and that their construction is a key driver for deforestation.Research Article: Engert et al.10:44 Research HighlightsHow climate change fuelled a record-bre...

Audio long read: Why are so many young people getting cancer? What the data say
Around the world, rates of cancers that typically affect older adults are increasing in those under 50 years old. Models based on global data predict that the number of early-onset cancer cases like these will increase by around 30% between 2019 and 2030.The most likely contributors — such as rising rates of obesity and early-cancer screening — do not fully account for the increase. To try and understand the reasons behind this trend, many researchers are searching for answers buried in studies that tracked the lives and health of children born half a century ago.This is an audio version of our Feature Why are so many ...

When did rats come to the Americas, and was Lucy really our direct ancestor?
Tracing the arrival of rats using bones, isotopes, and a few shipwrecks; and what scientists have learned in 50 years about our famous ancestor Lucy First on the show: Did rats come over with Christopher Columbus? It turns out, European colonists weren’t alone on their ships when they came to the Americas—they also brought black and brown rats to uninfested shores. Eric Guiry, a researcher in the Trent Environmental Archaeology Lab at Trent University, joins host Sarah Crespi to discuss how tiny slices of bone from early colony sites and sunken shipwrecks can tell us when these pesky rodents arrived. Next, producer M...

How climate change is affecting global timekeeping
In this episode:01:28 Inflammation’s role in memoryHow memories are stored is an ongoing question in neuroscience. Now researchers have found an inflammatory pathway that responds to DNA damage in neurons has a key role in the persistence of memories. How this pathway helps memories persist is unclear, but the researchers suggest that how the DNA damage is repaired may play a role. As inflammation in the brain is often associated with disease, the team were surprised by this finding, which they hope will help uncover ways to better preserve our memories, especially in the face of neurodegenerative disorders.Research Arti...

Hope in the fight against deadly prion diseases, and side effects of organic agriculture
New clinical trials for treatments of an always fatal brain disease, and what happens with pests when a conventional and organic farm are neighbors First up on this week’s show, a new treatment to stave off prion disease goes into clinical trials. Prions are misfolded proteins that clump together and chew holes in the brain. The misfolding can be switched on in a number of ways—including infection with a misfolded prion protein from an animal or person. Staff Writer Meredith Wadman talks with host Sarah Crespi about new potential treatments—from antisense nucleotides to small molecules that interfere with protein pr...

AI hears hidden X factor in zebra finch love songs
In this episode:00:48 How mysterious skyrmions could power next-generation computersSkyrmions are tiny whirlpools of magnetic spin that some researchers believe have useful properties that could unlock new kinds of computing. However getting skyrmions to perform useful computational tasks has been tricky. Now researchers have developed a method to create and manipulate skyrmions in a way that is compatible with existing computing technology, allowing them to read and write data at a fraction of the energy cost of conventional systems. The team think this shows that skyrmions could be a viable part of the next generation of...
