Science Magazine – March 31, 2023 issue: A new analysis shows that Great Plains tribes acquired horses much earlier than some historians had thought, consistent with Indigenous descriptions of a long and enduring partnership with the horse. This petroglyph, from the Tolar site in southern Wyoming, probably dates from soon after the modern horse became widespread in North America in the early 17th century.

Straight from the heart: Mysterious lipids may predict cardiac problems better than cholesterol

Conceptual illustration: a giant heart opens up on a hinge to reveal several gauges. Three of them, labeled HDL, LDL, and ApoB, display low levels. One, labeled Ceramides, displays high levels and is vibrating and letting off steam. Three tiny scientists stand at the foot of the heart, and one shines a flashlight on the Ceramides gauge.

Drug developers are now trying to target ceramides, which appear to contribute to a range of metabolic disorders

Science Magazine – March 17, 2023 issue: An alpine newt (Ichthyosaura alpestris) walks to a breeding pond in the Alps, France. Many amphibians have a cryptic upper side but a normally concealed, conspicuous underside. These hidden signals have evolved for several reasons, including as a warning display to would-be predators.

Lipids called ceramides may be better predictors of cardiovascular problems than cholesterol. Doctors and pharma are waking up to their potential

Bacteria require phase separation for fitness in the mammalian gut

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.
