Frequent Mosquito Bites May be Genetically Related

In a study by the London School of Hygiene and Tropical Medicine researchers have discovered that there is a gene that controls one's attractiveness to mosquito bites. The study contained 18 fraternal twins and 19 identical twins. Results showed that the similarity in attractiveness to mosquito bites was greater in the identical twins. Therefore they concluded that it was gene related, similar to genes that indicate one's height and IQ level. According to the study what caused whether or not a mosquito chose to bite you was due to the natural repellants produced by the body. The gene that scientists discovered cold either increase or decrease the amount of repellants produced.
This study can completely change the way that people protect themselves from mosquito bites. Using the information learned in this study scientists are one step closer to finding more effective ways to keep mosquitos at bay. This is most essential in some third world countries that have rampant mosquito infestations that carry serious life threatening diseases.

Gene Repelling against Spruce Budworm

Scientists from Université Laval, the University of British Columbia and the University of Oxford were researching spruce budworms and found a natural resistance gene in white spruce. "We could say the gene we discovered produces natural insecticides in the tree foliage," said Dr. Mackay. The gene they discovered was  betaglucosidase-1. They had measured expression levels up to about 24,000 genes between two tree groups.  The resistant spruce trees were 1,000 times higher than non-resistant.
