Zika virus detected in ‘a few’ units of donor blood in Florida

Zika virus has been detected in units of donated blood in Florida, federal health officials said Tuesday.

But the number so far is small, and new testing in high-risk areas kept the virus from entering the U.S. blood supply.

Food and Drug Administration officials confirmed that “a few” uni... Read More

A fungal infection that could help researchers to understand some allergies

Global warming collapses symbiotic gut bacteria, killing host insects

A new study shows that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted and can die. The study, reported online this week in the journal mBio®, illustrates another way globa... Read More

How the Zika Virus Could Make Its Way to North America

Laboratory tests show that a cold-tolerant mosquito known as Culex quinquefasciatus can be infected with Zika virus in the laboratory. If confirmed in the field, it would be a troubling development, suggesting the virus would be more difficult to control, and might be able to spread far north of... Read More
