Researchers report on mechanisms of gene regulatory divergence between species

Graphical abstract. Credit: Cell Genomics (2024). DOI: 10.1016/j.xgen.2024.100536 Closely related animal species can look physically different, but you might be surprised to learn that those differences can result not only from DNA sequence changes that alter proteins’ structure or function, but also because changes in the DNA affect how those proteins are expressed.

Simulated microgravity affects sleep and physiological rhythms

Simulated effects of microgravity significantly affect rhythmicity and sleep in humans, a new study from the University of Surrey finds. Such disturbances could negatively affect the physiology and performance of astronauts in space. Previous findings have shown that astronauts exposed to microgravity, simulated via 60 days of constant bed rest at a six-degree head-down tilt … Read more
