Close relatives have complicated relationships with each other even in the viral world. A new mouse study shows that if the animals have antibodies from dengue or West Nile virus, it sets them up for more severe disease from their close cousin, Zika virus.

If such "antibody-dependent enhancement" (ADE) also takes place in people, it could have helped fuel Zika's recent explosion in Brazil, where more than 90% of people in some communities have been infected with dengue. ADE could also complicate the development of vaccines for West Nile, dengue, and Zika. And with the onset of spring reigniting local transmission of Zika last week in the continental United States—where West Nile is widespread—ADE could give epidemiologists a new window into transmission and disease patterns.

Prototype dramatically cuts cost, time for detection of mosquito-borne illness

Add rapid, mobile testing for Zika and other viruses to the list of things that smartphone technology is making possible. Researchers have developed a smartphone-controlled, battery-operated diagnostic device that weighs under a pound, costs as little as $100 and can detect Zika, dengue and chikungunya within 30 minutes.

Sperm donated in three Florida counties since June 15 may be infected with the Zika virus, the United States Centers for Disease Control and Prevention cautioned Monday.

"When semen is donated it can be stored frozen for periods of time. It does not necessarily inactivate Zika, so it could be stored in tissue banks, used subsequently and people should be made aware," said Dr. Peter Marks, director of the Center for Biologics Evaluation and Research at the US Food and Drug Administration. He went on to say having this information can help individuals make informed decisions and they "might want to use these donations from other sources."

Sources other than the 12 sperm banks in Miami-Dade, Palm Beach and Broward counties of Florida, that is.

Electric car purchases have been on the rise lately, posting an estimated 60 percent growth rate last year. They’re poised for rapid adoption by 2022, when EVs are projected to cost the same as internal combustion cars. However, these estimates all presume the incumbent lithium-ion battery remains the go-to EV power source. So, when researchers this week at the University of Texas at Austin unveiled a new, promising lithium- or sodium-glass battery technology, it threatened to accelerate even rosy projections for battery-powered cars.
