Lipids called ceramides may be better predictors of cardiovascular problems than cholesterol. Doctors and pharma are waking up to their potential
The gut microbiota is critical for human health. Understanding how beneficial bacteria colonize the gut enables medical interventions that promote gut health. Krypotou et al. discovered a mechanism that enhances the fitness of a commensal bacterium in the gut.
But will doctors embrace the grainier, lower-resolution images of the body’s insides?

Genes reveal striking diversity within similar ice age cultures
Our capability to reconstruct past landscapes and the processes that shape them underpins our understanding of paleo-Earth. We take advantage of a global-scale landscape evolution model assimilating paleoelevation and paleoclimate reconstructions over the past 100 million years.
The Hayabusa2 spacecraft made two landings on the asteroid (162173) Ryugu in 2019, during which it collected samples of the surface material. Those samples were delivered to Earth in December 2020. The colors, shapes, and morphologies of the returned samples are consistent with those observed on Ryugu by Hayabusa2, indicating that they are representative of the asteroid.
