When male fetuses are missing one copy of the gene, it throws off their developmental process enough to lead to autism but female biology differs enough that it doesn't matter.

Scientists have long wondered why autism is much more common among males than females. When males miss one copy of a gene it messes up the development process enough to cause autism but female biology differs enough to make it not matter. Now that scientists have identified that the SHANK 1 gene is involved they can test for it and could offer treatments early.

Genetically modified mosquitoes that cannot transmit malaria are one hope for battling the disease that still kills over one million people a year. But that plan faces some serious snags, according to UC Davis researchers who are suggesting an alternative strategy.

Transposons are essentially DNA parasites that snip themselves in or out of the genome under the right circumstances. Scientists can add a new gene into a transposon and use it to carry that DNA into the insect genome. But it's in the interest of that transposon to just get rid of the extra DNA,
