Ever since scientific enquiry began, people have focused mainly on men, or if studies involve animals, on male mice, male rats or whatever it may be. And this has led to gaps in scientists’ understanding of how diseases, and responses to treatment, and many other things might vary between people of different sexes and genders. These days, mainly thanks to big funders like the NIH introducing new guidelines and mandates, a lot more scientists are thinking about sex and, where appropriate, gender. And this has led to a whole host of discoveries.
But all this research is going on within a sociopolitical climate that’s becoming increasingly hostile and polarized, particularly in relation to gender identity. And in some cases, science is being weaponized to push agendas, creating confusion and fear.
It is clear that sex and gender exist beyond a simple binary. This is widely accepted by scientists and it is not something we will be debating in this podcast. But this whole area is full of complexity, and there are many discussions which need to be had around funding, inclusivity or research practices.
To try to lessen fear, and encourage clearer, less divisive thinking, we have asked three contributors to a special series of opinion pieces on sex and gender to come together and thrash out how exactly scientists can fill in years of neglected research – and move forward with exploring the differences between individuals in a way that is responsible, inclusive and beneficial to as many people as possible.

Talking about sex and gender doesn't need to be toxic

In this episode:00:46 Using genomics to explain geographic differences in cancer riskThe risk of developing cancer can vary hugely depending on geographic region, but it’s not exactly clear why. To get a better idea, a team has compared the genomes of kidney cancers taken from people around the globe. They reveal a link between geographical locations and specific genetic mutations, suggesting that there are as-yet unknown environmental or chemical exposures in different locations. They hope this work will inform public health efforts to identify and reduce potential causes of cancer.

09:55 How disrupting a male mouse’s microbiome affects its offspringDisruption of the gut microbiota has been linked to issues with multiple organs. Now a team show disruption can even affect offspring. Male mice given antibiotics targeting gut microbes showed changes to their testes and sperm, which lead to their offspring having a higher probability of severe growth issues and premature death. Although it’s unknown whether a similar effect would be seen in humans, it suggests that factors other than genetics play a role in intergenerational disease susceptibility.

Dad's microbiome can affect offsprings' health — in mice

Many people around the world feel lonely. Chronic loneliness is known to have far-reaching health effects and has been linked to multiple conditions and even early death. But the mechanisms through which feeling alone can lead to poor health is a puzzle. Now, researchers are looking at neurons in the hopes that they may help explain why health issues arise when social needs go unmet.

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.
