Identification of gene in mosquitoes that helps them to fight off infection by the Plasmodium parasite

Researchers have identified a gene in mosquitoes that helps the insects to fight off infection by the Plasmodium parasite, which causes malaria in humans. Anopheles mosquitoes transmit the malaria parasite to nearly 550 million people worldwide each year with these cases resulting in more than 2 million deaths annually.

Cholesterol levels and use of statins are not associated with breast cancer risk

Although some evidence suggests that statins (the most commonly used type of lipid-lowering drugs) may inhibit tumor development and may work in combination with chemotherapy drugs against cancer, studies on the association between the use of statins and breast cancer have had conflicting results

Maximum longevity inherited from the father

The parts of the genetic make-up that are thought to determine an individual’s maximum possible longevity, so-called telomeres, are inherited from the father but not the mother. This is shown by a research team at Umea University in the coming issue of the U.S. scientific journal Proceedings of the National Academy of Sciences.
