The authors conclude that the altered light/dark or feeding schedules may slow tumor growth in chronic jet-lagged mice.
The Hudson River has seen a doubling of dissolved organic carbon (DOC) in the past 15 years, with possible causes including changes in river materials and bacterial metabolism. This increase may be linked to nitrogen deposition, leading to eutrophication-driven problems such as hypoxia.
Researchers at Yale University identified IRAK-M as a key regulator of bone cells, finding that its presence prevents bone loss and its absence leads to severe osteoporosis in mice. The study suggests IRAK-M could be a new target for treating or preventing osteoporosis.
