00:46 Using genomics to explain geographic differences in cancer risk
The 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.

07:46 Research Highlights
Research reveals that the extinct ‘sabre-toothed salmon’ actually had tusks, and a common fungus that can clean up both heavy-metal and organic pollutants.

09:55 How disrupting a male mouse’s microbiome affects its offspring
Disruption 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.
