Mineralization of sand particles boosts microbial water filtration

Researchers found that microbial activity increases with mineral deposits on sand particles in rapid sand filters, removing impurities like iron and ammonia. The study refutes the conventional assumption that minerals interfere with microbial colonization, suggesting potential improvements in drinking water production.

CNIO researchers associate 2 oncogenes with the aggressiveness and incidence of leukemia in mice

CNIO researchers found that the simultaneous inhibition of Cdk4 and Cdk6 is more effective than individual inhibition in reducing tumour growth and promoting aggressive tumours in mice. The study also revealed that the combined activation of both oncogenes leads to uncontrolled cell division and an increased risk of developing leukemia.
