A System of Check and Balances in the Blood

University of Vienna

Hematopoietic Stem Cells (HSCs) give rise to blood and immune cells of the body, and are therefore essential for our survival. They are in a dormant state, but whenever new blood needs to be formed, such as after blood loss or chemotherapy, they are rapidly activated to compensate for the loss. After completing their mission, they need to go back to their dormant state. The group of Manuela Baccarini at the Max F. Perutz Laboratories, a joint venture of the University of Vienna and the Medical University of Vienna, has now shown how intracellular signalling can safeguard this delicate balance between activation and dormancy. Their results are published in the prominent journal Cell Stem Cell.

Lack of Paid Sick Leave Increases Poverty

Florida Atlantic University

A new study has quantified, for the first time, the relationship between lack of paid sick leave and poverty in the U.S. The data indicates that, even when controlling for education, race, sex, marital status and employment, working adults without paid sick leave are three times more likely to have incomes below the poverty line. People without paid sick leave benefits also are more likely to experience food insecurity and require welfare services.
