Gene-transfer system may control mosquito-borne diseases without pesticides

Scientists have modeled a system that may be used to control mosquitoes and the diseases they transmit, without the use of pesticides. In the proposed system, mosquitoes are engineered to carry two genes. The first gene causes males to transmit a toxin to females through their semen. The second gene, when expressed in females, makes them immune to this toxin.

Pyrethroid insecticides linked to delayed mental development in children

When the EPA phased out the widespread residential use of chlorpyrifos and other organophosphorus (OP) insecticides in 2000-2001 because of risks to child neurodevelopment, these compounds were largely replaced with pyrethroid insecticides. But the safety of these replacement insecticides remained unclear, as they had never been evaluated for long-term neurotoxic effects after low-level exposure.

Regulatory changes needed to protect public health from exposure to toxicants

Americans are exposed to hundreds, if not thousands, of suspected toxic substances every day, substances that affect the development and function of the brain, immune system, reproductive organs or hormones. Children are the most vulnerable. But no public health law requires product testing of most chemical compounds before they enter the marketplace.

Organic milk best: Study

The latest research published by Newcastle University, UK has shown that organic milk contains less unhealthy fat, as well as a range of important healthy nutrients. It contains fewer chemicals and poses less risk for children to develop allergies and eczema. Organic milk is also rich in omega 3 fatty acids that re good for the heart. However it costs more. At least 60 per cent of the diet of organic cows has to be organically grown grass and its traditional derivatives — silage and hay.

Banned chemicals found in pregnant women

The bodies of virtually all U.S. pregnant women carry multiple chemicals, including some banned since the 1970s and others used in common products such as non-stick cookware, processed foods and personal care products, according to a new study from UCSF. The study marks the first time that the number of chemicals to which pregnant women are exposed has been counted.

Plant-derived bioscavenger protects against pesticide and nerve agent organophosphate poisoning

The brain is forever chattering to itself, via electrical impulses sent along its hard-wired neuronal "Ethernet." These e-messages are translated into chemical transmissions, allowing communication across the narrow cleft separating one neuron from another or between neurons and their target cells. Of the many kinds of molecules involved in this lively chemical symposium, acetylcholine is among the most critical, performing a host of functions in the central and peripheral nervous system.
