Chikungunya poised to invade the Americas

EurekAlert Jil Sliwa 7 April 2014

A team of French and Brazilian researchers warn that chikungunya virus is poised to invade, and become epidemic in the Americas according to research published ahead of print in the Journal of Virology.

The risk of a “catastrophic” epidemic in the Americas is boosted by the FIFA World Cup, to be held in Brazil next month, what with people coming in from near and from far, says corresponding author Ricardo Lourenco-de-Oliveira of the Instituto Oswaldo Cruz in Rio de Janeiro, Brazil. Brazil annually reports the highest incidence of dengue, a virus that is transmitted by Aedes aegypti and Aedes albopictus, the same mosquitoes that transmit chikungunya, he says.

Scientists generate 3D structure for the malaria parasite genome

(University of California – Riverside 4 April 2014) A research team led by a University of California Riverside scientist has generated a 3-D model of the human malaria parasite genome at three different stages in the parasite’s life cycle — the first time such 3-D architecture has been generated during the progression of the life cycle of a parasite. The team found that genes that need to be highly expressed in the parasite tend to cluster in the same area of the cell nucleus.

Mozzie squad sets sights on Dengue

Townsville bulletin Daniel Bateman 2 April 2014

THE bloodsuckers captured in these traps may one day help control the spread of dengue fever around the world.

The Eliminate Dengue research project has officially started in Townsville, with researchers deploying traps to monitor local mosquito populations.

There are currently 10 confirmed cases of dengue in Townsville since an outbreak was declared on January 30, 120 cases of the mosquito-borne virus in Cairns/Innisfail, and 17 cases in Port Douglas/Miallo.

The Eliminate Dengue project involves releasing mosquitoes infected with a naturally occurring bacteria, called wolbachia, that has been proven to block mozzies from infecting people with the potentially fatal virus.

Climate change and health: IPCC reports emerging risks, emerging consensus

The Conversation Anthony McMichael, Colin Butler, Helen Louise Berry 31 March 2014

The consequences of human-driven global climate change as this century progresses will be wide-ranging. Yet public discussion has focused narrowly on a largely spurious debate about the basic science and on the risks to property, iconic species and ecosystems, jobs, the GDP and the economics of taking action versus taking our chances.
