Free birth control doesn’t promote risky sexual behavior in women
Researchers at the School of Medicine have shown that providing women with free contraception does not increase the likelihood that they will have sex with multiple partners, as critics of the practice have suggested. Shown is the study’s first author, Gina Secura, PhD.
Heads or tails? Random fluctuations in brain cell activity may determine toss-up decisions
Coffee or tea? One of founders of an emerging field that combines economics and brain science reports new insights into decisions in which two choices are equally appealing.
Study emphasizes birth control education, helps pay for IUDs and implants
Researchers at the School of Medicine want to know whether they can reduce the rate of unintended pregnancies at community clinics by providing contraceptive counseling that emphasizes the benefits of long-acting birth control, like IUDs and implants, and by making these methods available to women at sharply reduced costs or free of charge. Pictured is Tessa Madden, MD, the study’s principal investigator.
Abortion rates plummet with free birth control
Providing birth control to women at no cost substantially reduced unplanned pregnancies and cut abortion rates by 62 percent to 77 percent over the national rate, a new study shows.
Certain female fish have special mating preference
Male Bahamas mosquitofish (left) chasing a female (right).A biologist at Washington University in St. Louis has shown that for some fish species, females prefer males with larger sexual organs, and actually choose them for mating. That does not exclude males with an average-sized sex organ, called a gonopodium. These fish out-compete the larger-endowed males in a predator-laden environment because they have a faster burst speed than the males with larger genitalia, thus avoiding predators and staying in the mating game.
