  • The Unlikely Politics of a Digital Contraceptive | The New Yorker

    In August, the F.D.A. announced that it had allowed a new form of contraception on the market: a mobile app called Natural Cycles. The app, which was designed by a Swedish particle physicist, asks its users to record their temperature with a Natural Cycles-branded thermometer each morning, and to log when they have their periods. Using a proprietary algorithm, the app informs its users which days they are infertile (green days—as in, go ahead, have fun) and which they are fertile (red days—proceed with caution), so that they can either abstain or use a backup method of birth control. In clearing the app as a medical device, the F.D.A. inaugurated “software application for contraception” as a new category of birth control under which similar products can now apply to be classified. The F.D.A.’s press release quotes Terri Cornelison, a doctor in its Center for Devices and Radiological Health, who said, “Consumers are increasingly using digital health technologies to inform their everyday health decisions and this new app can provide an effective method of contraception if it’s used carefully and correctly.”

    On touche vraiment au grand Ogin’importe quoi.

    In January, a single hospital in Stockholm alerted authorities that thirty-seven women who had sought abortions in a four-month period had all become pregnant while using Natural Cycles as their primary form of contraception. The Swedish Medical Products Agency agreed to investigate. Three weeks ago, that agency concluded that the number of unwanted pregnancies was consistent with the “typical use” failure rate of the app, which they found to be 6.9 per cent. During the six-month investigation, six hundred and seventy-six additional Natural Cycle users in Sweden reported unintended pregnancies, a number that only includes the unwanted pregnancies disclosed directly to the company.

    Berglund’s story—a perfect combination of technology, ease, and self-discovery, peppered with the frisson of good fortune and reliance on what’s natural—has helped convince more than nine hundred thousand people worldwide to register an account with Natural Cycles. But the idea of determining fertile days by tracking ovulation, known as a fertility-awareness-based method of birth control, is anything but new. Fertility awareness is also sometimes called natural family planning, in reference to the Catholic precept that prohibits direct interventions in procreation. The most familiar form of fertility awareness is known as the rhythm method. First designated in the nineteen-thirties, the rhythm or calendar method was based on research by two physicians, one Austrian and one Japanese. If a woman counted the number of days in her cycle, she could make a statistical estimate of when she was most likely to get pregnant. Those methods evolved over the years: in 1935, a German priest named Wilhelm Hillebrand observed that body temperature goes up during ovulation. He recommended that women take their temperature daily to determine their fertile period.

    Plenty of doctors remain unconvinced about Natural Cycles. “It’s as if we’re asking women to go back to the Middle Ages,” Aimee Eyvazzadeh, a fertility specialist in San Francisco, said. Technology, she warned, “is only as reliable as the human being behind it.” Forman, from Columbia, said that “one of the benefits of contraception was being able to dissociate intercourse from procreation.” By taking a pill or inserting a device into an arm or uterus, a woman could enjoy her sexuality without thinking constantly about what day of the month it was. With fertility awareness, Forman said, “it’s in the opposite direction. It’s tying it back together again. You’re having to change your life potentially based on your menstrual cycle. Whereas one of the nice benefits of contraception is that it liberated women from that.”

    Animation of data from collisions at the LHCCERN Several years ago, particle physicist Lily Asquith was hanging out with a few musician pals in London after a band rehearsal, doing impromptu impersonations of what she thought the various elementary particles might sound like, and encouraging the drummer to recreate them electronically. Another band member asked if it would be possible to create sounds based on actual data from an accelerator, and the LHCsound project was born.LHCsound is a (...)
