In sync? Malaria parasite and human time clocks do align

A study by Florida Atlantic University and Duke University reveals that the malaria parasite's biological clock is 'in sync' with its human host's circadian clock. The researchers discovered a 'coupling' mechanism between the parasite and its host, which could lead to new treatments for this deadly disease.

Cause of leukemia in trisomy 21

Children with Down syndrome are highly vulnerable to developing aggressive leukaemia due to a defect in the RUNX1 gene, which regulates blood cell formation. Researchers have identified a specific variant of the gene that promotes leukaemia development and discovered potential therapeutic approaches to correct this malfunction.
