Special insecticide paint may help curb zika and dengue fever outbreaks
Scientists showed that insecticide paint could effectively decrease mosquito presence in Cabo Verde (Cape Verde) for up to one year, making this paint a potential strategy to decrease the transmission of vector-borne diseases.

Researchers develop a new toolkit in fruit flies to study Zika virus
To study how Zika virus proteins hijack and disrupt host developmental pathways during infection and disease progression, scientists have generated a toolkit of transgenic flies expressing all ten Zika virus proteins.

Researchers to probe how Zika virus replicates and transmits from mother to fetus
Nearly $6 million in new NIH grants will enable researchers to investigate how Zika virus replicates and crosses the placenta to infect unborn children.

News
Prior zika infection increases risk of subsequent severe dengue and hospitalization
A study suggests that the mechanism that exacerbates dengue infection following a case of zika differs from that acting on second-time dengue patients. The finding is relevant to the development of a zika vaccine.

News
Cases of chikungunya and zika fall in Brazil, but most risk clusters rise
Researchers observed spatial and temporal patterns of occurrence and co-occurrence for the two arboviral diseases in all Brazilian municipalities, alongside the influence of environmental and socio-economic factors.

News
Zika virus is effective when used to treat a type of childhood cancer in mice
Injecting neuroblastoma tumors with Zika virus shrank or eliminated those tumors in studies with mice, suggesting that the virus could someday serve as an effective cancer therapy, according to a new study.

Industry collaboration funds development of RNA drugs against dengue fever virus
University team use patented nuclear magnetic resonance (NMR)-based screening method to identify small molecules that specifically bind to the viruses’ highly conserved RNA structures and interrupt the viral infection cycle.

News
Reduced activity of key enzyme linked to microcephaly in Zika-infected offspring
Researchers have shown that brain activity of Ndel1, an enzyme that plays an important role in neuron differentiation and migration, decreased in mice infected by Zika during pregnancy.

News
Researchers combat Zika-associated foetal abnormalities using microRNA
Researchers have studied how the Zika virus persists in the placenta for long periods of time and how to mitigate it.

News
Discovery in mosquitoes could lead to new strategy against dengue fever
Researchers have discovered that a protein in the mosquito Aedes aegypti , Argonaute 2, has a key role - via several biological mechanisms - in keeping mosquitoes healthy and active despite the presence of viral infections like dengue and Zika.

News
Novel molecules fight viruses by bursting their bubble-like membranes
Researchers show how a group of novel molecules inspired by our own immune system inactivates several viruses, including Zika and chikungunya, by targeting the viral membranes, rather than the proteins.
