In the next year, no fewer than seven missions are heading to the Moon. While NASA's Artemis programme might be stealing most of the limelight, the United States is just one of many nations and private companies that soon plan to launch lunar missions.
Although some of the agencies running these expeditions are providing scant details about the missions, it is hoped the they will provide streams of data about the Moon, heralding what scientists say could be a new golden age of lunar exploration.

In this episode:
00:46 Optical clocks at seaOptical atomic clocks are the most precise timekeeping devices on the planet, but these devices are huge and difficult to work with, limiting their use outside of the lab. Now, researchers have developed a portable optical clock and demonstrated its robustness by sending it on a perilous sea journey. The team hope that this work will pave the way to more practical uses of optical clocks, such as on satellites where they could help improve the accuracy of GPS technologies.

11:52 How marsupial gliding membranes evolvedSeveral marsupial species have evolved a membrane called a patagium that allows them to glide gracefully from tree to tree. Experiments show that mutations in areas of DNA around the gene Emx2 were key to the evolution of this ability, which has appeared independently in multiple marsupial species.

How gliding marsupials got their 'wings'

Humans setting up home in outer space has long been the preserve of science fiction. Now, thanks to advances in technology and the backing of billionaires, this dream could actually be realised. But is it more likely to be a nightmare?
Kelly and Zach Weinersmith join us to discuss their new book A City on Mars and some of the medical, environmental and legal roadblocks that may prevent humanity from ultimately settling in space.

Living on Mars would probably suck — here's why

00:46 Mysterious methane emission from a cool brown dwarfThe James Webb Space Telescope (JWST) is revealing the makeup of brown dwarfs — strange space objects that blur the line between a planet and a star. And it appears that methane in the atmosphere of one of these objects, named W1935, is emitting infrared radiation. Where the energy comes from is a mystery however, researchers hypothesise that the glow could be caused by an aurora in the object’s atmosphere, perhaps driven by an as-yet unseen moon.

13:07 How working memory worksWorking memory is a fundamental process that allows us to temporarily store important information, such as the name of a person we’ve just met. However distractions can easily interrupt this process, leading to these memories vanishing. By looking at the brain activity of people doing working-memory tasks, a team have now confirmed that working memory requires two brain regions: one to hold a memory as long as you focus on it; and another to control its maintenance by helping you to not get distracted.

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.

The 'ghost roads' driving tropical deforestation

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.
