Female scientists do about twice as many household chores as male scientists, according to a Stanford University study in the current issue of Academe. “Partnered women scientists at places like Stanford University do 54 percent of the cooking, cleaning, and laundry in their households; partnered men scientists do just 28 percent,” write authors Londa Schiebinger and Shannon Gilmartin, who also show that women work the same number of hours, 56, at their paying jobs.
