In monkeys infected with Ebola, this diagnostic, called the D4-assay, proved to be 1000 times more sensitive than the currently approved rapid diagnostic test and capable of detecting the virus a full day earlier than the gold standard polymerase chain reaction (PCR) test. This work, which appears in Science Translational Medicine on April 7, was done by biomedical engineers, molecular b...

8 For years, scientists have warned the Nipah virus -- a brain-swelling disease 75 times more deadly than COVID -- could be the next pandemic. Knowing that this fruit bat-borne virus has the potential to trigger an epidemic, researchers at the Uniformed Services University (USU) have long studied the virus and recently reported on the development of a single-dose vaccine that, in preclinical trials, has proven effective against it as early as seven days after immunization. The Nipah virus first emerged in the late 1990s, causing serious disease outbreaks in humans and livesto...
