A study of Nicaraguan children links prior Zika virus infection with aggravated dengue fever symptoms.

There have been no reports of health or environmental harm in other locations where genetically modified mosquitoes have been introduced over the last decade.

Elevated levels of a neurotoxin in northeastern Brazil’s drinking water and a high incidence of microcephaly in the region led scientists to look for a link, and they found one.

By infecting glioblastoma cells but not healthy brain tissue, some form of the virus could serve a therapeutic purpose.

The biotech Oxitec had released the genetically engineered insects with the hope that they would breed with wild populations and produce offspring that die young. But that’s not always happening.

Researchers use two techniques—Wolbachia infection and irradiation—to suppress reproduction in populations of Asian tiger mosquitoes at two study sites in China.

Executives at a biotech that develops new antibodies argue that Ram Sasisekharan didn’t come up with the structures for at least two experimental therapies that his group has described.

Animal and cell culture studies show evidence that dengue antibodies can both neutralize and enhance Zika, but human investigations have only found protective effects.

Children were 38 percent less likely to show signs of Zika infection if they had previously had dengue.
