milhayser | March 31, 2014Scientists use a 'gene gun' to insert a gene from a flowering plant called rockcress into the cells of wheat seeds. The genetically modified wheat became more resistant to a fungus called take-all, which in real life can cause "a 40-60% reduction in wheat yields."
T-cells from six HIV+ patients were removed from their bodies, treated with a zinc-finger nuclease designed to snip a gene out of the cell's DNA, and put back in the patients. Removal of the gene mimics a naturally occurring mutation which confers resistance to the HIV virus. But only 25% of the treated cells showed evidence of…
edyong | November 10, 2009Will you have that extra chocolate bar when you're worried about your weight? Will you spend that extra hour on the internet when you have other things to do? Will you have that extra drink with an attractive colleague when your partner is waiting at home? Our lives are full of temptations and some of us are better at resisting them than others. But unexpectedly, the very people who think they are most restrained are also most likely to be impulsive. Their inflated belief in their own self-control leads them to overexpose themselves to temptation.
In a series of four experiments, Loran…
edyong | April 14, 2009Learning a new language as an adult is no easy task but infants can readily learn two languages without obvious difficulties. Despite being faced with two different vocabularies and sets of grammar, babies pick up both languages at the same speeds as those who learn just one. Far from becoming confused, it seems that babies actually develop superior mental skills from being raised in a bilingual environment.
By testing 38 infants, each just seven months old, Agnes Melinda Kovacs and Jacques Mehler have found that those who are raised in bilingual households have better "executive functions…
