The widely used insect repellent Deet appears to be losing its effectiveness against mosquitoes, scientists say. Researchers from the London School of Hygiene and Tropical Medicine say mosquitoes are first deterred by the substance, but then later ignore it. They say more research is needed to find alternatives to Deet, which was first developed by the US military. The research was carried out on Aedes aegypti, a species of mosquito that spreads dengue and yellow fever.The findings are published in the journal Plos One.
Malaria in pregnancy causes a range of adverse effects, including abortions, stillbirths, premature delivery and low infant birth weight. Many of these effects are thought to derive from a placental inflammatory response resulting from interaction of infected red blood cells with the placental tissue. In a study published in the latest issue of the journal PLOS Pathogen, a researchers' team led by Carlos Penha-Gonçalves at the Instituto Gulbenkian de Ciência (IGC), Portugal, observed, for the first time, the mouse placental circulation and showed how it can influence the malaria parasite behavior and infection. Their results indicate a higher accumulation of parasites in placental regions with low blood flow, being these areas more prone to an inflammatory response.
We’re close to Christmas, which can only mean one thing: Yes, consumer electronics manufacturers are gearing up for big CES event in Las Vegas on January 6.

[NAIROBI] A WHO recommendation to supply all iron-deficient children with micronutrient supplements has been called into question by a study that has found this may increase the risk of malaria. Giving supplements containing iron, folic acid, copper and vitamins to more than 600 Tanzanian children — aged between six months and five years — with iron deficiency increased their likelihood of contracting malaria by 41 per cent, researchers found.
