A huge analysis of hiring practices has revealed that criteria to get a promotion to full professorship is hugely variable around the world. The authors suggest that this variability results in researchers from countries that value one type of metric being locked out of professor positions in others. They hope that the database of hiring practices created in this study could help institutions adjust their hiring policies to create a more diverse science workforce.

Researchers have shown that cancer cells can slip their dysfunctional mitochondria into T cells, limiting the immune system’s cancer-fighting capabilities. Cancer cells are known to steal healthy mitochondria from immune cells to help tumours survive and thrive. Now, researchers have shown mitochondria can move in the opposite direction too, with the donor T cells showing signs of various stress responses that make them less effective when inside a tumour. The team showed that blocking this transfer limited this effect, and hopes that this mechanism could offer a new avenue for boosting the immune system’s response to cancer.
