New GM technique injects mosquitoes with a gene that results in mostly male offspring, eventually leading to a population crash.
Previous efforts to tackle the disease, that kills more than 1 million people each year – most of whom are African children – have included bed nets to protect people and insecticides to kill the mosquito species most responsible for the transmission of malaria (Anopheles gambiae
). The new technique by a team at Imperial College London involves injecting mosquitoes with a gene that causes the vast majority of their offspring to be male, leading to an eventual dramatic decline in population within six generations as females disappear. “You have a short-term benefit because males don’t bite humans [and transmit malaria],” Andrea Crisanti, one of the authors of the new research, which was published in the journal Nature Communications on Tuesday
, told the Guardian. “But in the long term you will eventually eradicate or substantially reduce mosquitoes. This could make a substantial contribution to eradicating malaria, combined with other tools such as insecticides.”
These new mosquitoes are now set to be used in Brazil, having been approved for use by the Brazilian government with a factory for their production now opened. [more inside]

Less than two weeks after a controversial paper came to light advocating the pre-natal treatment of some female fetuses with a hormone to make their behavior more stereotypically female (previously discussed here
) comes news of actual animal research on causing the opposite inclination. By knocking out the fucose mutarotase gene, scientists in South Korea have apparently created "Lesbian mice" who prefer other female mice and who resist the attempts of male mice to mate with them. Article abstract

Scientists in Australia have discovered a new gene.
Called BRCA3, this genetic mutation causes up to 10% of the breast cancer cases which run within families. This breakthrough completes the search for the trilogy of gene mutations. The first two gene mutation markers were discovered in 1994 and 1995 respectively.

"Language Gene" found...
(link to arstechnica
"A group of Oxford University researchers presented findings in this week's Nature that they isolated a gene called FOXP2 that appears to be involved in both speech and language development." this is intriguing... that so much can start from so little.

Isolating the gene responsible for caffeine
is expected to lead to decaffeinated beans, and a higher-quality coffee product, all-around... But are they considering other applications? With a bit of gene splicing, anything is possible. Caffeinated oranges, anyone?
