‘Cheeky’ discovery allows scientists to estimate your risk of dying using cells found in the mouth

Over the past decade, several epigenetic clocks have been developed to track physiological aging. Until recently, all had been based on the DNA methylome of blood cells – onerous and stressful to collect. But now, scientists from the US have shown for the first time that their new epigenetic clock CheekAge, which uses easy-to-collect cheek cells, can accurately predict mortality. This suggests that cheek swabs could be an improved way to measure and predict healthy vs unhealthy aging and mortality in humans.

Oceanic life found to be thriving thanks to Saharan dust blown from thousands of kilometers away

Scientists from the US measured the relative amounts of ‘bioreactive’ iron in four sediment cores from the bottom of the Atlantic. They showed for the first time that the further dust is blown from the Sahara, the more iron in it becomes bioreactive through chemical processes in the atmosphere. These results have important implications for our understanding of the growth-promoting effect of iron on oceanic phytoplankton, terrestrial ecosystems, and carbon cycling, including under global change.
