What's the best way to become a professor? The answer depends on where you are

00:56 How the paths to professorship varyA 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.Research Article: Lim et al.News: Want to become a professor?

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.Research Article: Ikeda et al.News & Views: Mitochondrial swap from cancer to immune cells thwarts anti-tumour defences21:12 Science and the Gaza conflictNoah Baker and Ehsan Masood turn to the war in Gaza, and discuss what comes next for science as a ceasefire comes into force.Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
