Acinetobacter baumannii found growing in nearly half of infected patient rooms

A study found that environmental growth of Acinetobacter baumannii was detected in 48% of patient rooms, with surfaces like supply cart handles and floors being most commonly contaminated. Patients with recent or remote MDR-AB colonization or infection showed similar levels of environmental contamination.

Structure, not scientists to blame for Los Alamos failings

The article reveals how Los Alamos' decline is linked to misguided policies and mismanagement, rather than a culture of arrogance. The lab's scientists faced harsh conditions, including polygraph tests and shutdowns, after media scrutiny of one individual's actions was misconstrued as institutional failure.
