Fire ant venom compounds may lead to skin treatments

Compounds derived from fire ant venom can reduce skin thickening and inflammation in a mouse model of psoriasis, Emory and Case Western scientists have shown. The results are scheduled for publication in Scientific Reports. The findings could lead to new treatments for psoriasis, a common autoimmune skin disease. Topical steroids are now most frequently used [...]

Folic acid may mitigate autism risk from pesticides

Researchers at UC Davis and other institutions have shown that mothers who take recommended amounts of folic acid around conception might reduce their children’s pesticide-related autism risk. In the study, children whose mothers took 800 or more micrograms of folic acid (the amount in most prenatal vitamins) had a significantly lower risk of developing autism [...]
