Washington University in St. Louis researchers developed a diagnostic test for the Zika virus that uses gold nanorods on paper that change color if the blood sample contains the pathogen, also yielding results in minutes, according to a study published in the journal Advanced Biosystems. No false-positive results were generated when the investigators tested the assay on four people infected with Zika compared with blood samples from five uninfected people.

The glycan binding protein Y3 found in the Coprinus comatus mushroom, more commonly known as "shaggy ink cap," was discovered by University of Florida researchers to be associated with activating a cell-signaling cascade that programs a specific leukemia T cell type to kill itself, according to the journal Proceedings of the National Academy of Sciences. The study suggests the use of this protein could affect potential new therapies for patients with acute lymphoblastic leukemia.

Baylor College of Medicine researchers are developing virus-specific cells -- including for the Epstein-Barr virus, adenoviruses, cytomegalovirus, BK virus and human herpesvirus 6 -- to treat viral infections in patients who receive hematopoietic stem cell transplants, according to a study in the Journal of Clinical Oncology. Thirty-eight patients received a single infusion, and the overall complete or partial response rate was 92%.
