Two recent studies argue that smartphones may have contributed to falling birthrates by reducing in-person social interaction, sexual frequency, and other conditions tied to unintended pregnancies. "One of the studies published in May is called 'The Collapse of Teen Fertility in the Digital Era' and the other, published just Monday, is titled 'Is the iPhone Birth Control? Causal Evidence from AT&T's 2007-2011 Carrier Monopoly,'" reports KTLA. "Both were chronicled in a New York Times piece by political writer Sabrina Tavernise on Monday." Slashdot reader sabbede submitted the story. From the report: The one from May, authored by two University of Cincinnati professors, posits that teen fertility "collapsed globally" starting around 2007 -- the same year the first iPhone was released. "Smart phones changed how teens spend time with each other ... this change in turn drove the collapse in teen fertility," the study's abstract reads. "Once enough teens are on the phone, being on the phone is where the peer network is; in-person time falls sharply, and with it the unstructured contact in which most unintended teen conceptions occur." The study claimed that countries "across the income and policy spectrum" were affected by the teen fertility drop, and that researchers used data from multiple countries, including the U.S., England and Wales, to rule out "country-specific contraceptive access and welfare reform stories." "This model predicts that the shift towards the phone-mediated equilibrium affects multiple aspects of teen behavior," the abstract continues, concluding that "the same instrument that produces a collapse in teen fertility produces a surge in teen suicides."
The study published on Monday looks more closely at the United States, explaining that nationwide general fertility rates have fallen 22% since 2007. "[This is] a sustained decline not readily explained by economic conditions, contraceptive use, housing or childcare costs, or other commonly cited factors," the National Bureau of Economic Researchers study states. "We assess the potential role of a different shock: the diffusion of the smartphone." As mentioned before, the first iPhone was rolled out in 2007, and this study makes use of that timeframe as "a natural experiment" by using data from 2007 through 2011, when iPhones were only sold on AT&T. "From June 2007 through February 2011, the device was sold only on AT&T, allowing us to identify its effect from variation in AT&T's mobile broadband coverage," the study says. "Entropy-balanced Poisson and synthetic difference-in-differences event studies imply that access to the iPhone reduced births by 4.5-8.0% at ages 15-19 and 3.2-6.6% at ages 20-24, with statistically significant but smaller declines among older cohorts. Placebo analyses applied to Verizon and Sprint's pre-2011 coverage footprint are null.
Taken together, these cohort effects imply that the diffusion of the iPhone deepened the decline in births among women under 30 while suppressing the rise in births among older women." "Overall, the diffusion of the iPhone explains 33-52% of the decline in the general fertility rate among women aged 15-44," researchers continued. "National-survey evidence on time use and sexual behavior is consistent with the iPhone reducing in-person interactions, increasing pornography use and reducing sexual frequency."

Polish lawmakers have voted to criminalize "trash streaming," with up to five years in prison for online broadcasts of serious crimes such as rape or murder, animal cruelty, humiliating violence, gambling promotion, or even simulated depictions of those acts. Reuters reports: The move is part of a broader push by Poland to tighten regulation of online content. Recent measures include banning the use of mobile phones by children under 16 in schools and introducing stricter age verification rules to access pornography. Under the new provisions, broadcasting crimes punishable by more than five years in prison, including murder or rape, will itself be classed as a separate offence punishable by up to five years behind bars.
The law also covers content showing cruelty to animals, violence aimed at humiliating others, and the promotion of gambling. The same penalties will apply to individuals who simulate or falsely portray the commission of such crimes while streaming, lawmakers said.

Recently, Panasonic released firmware V2 for the Panasonic S9, which lets you use the camera with the latest version of the Lumix Lab app. That makes it a pretty exciting update, as Lumix Lab V3 adds a ton of new features, like the ability to edit Raws, download images via a wired connection, edit your custom color modes with the app and more. However, if you're trying to update your camera, you'll want to do so using a computer, rather than the app.
Panasonic posted a notice to its site saying it's "identified an issue with the DC-S9 version 2.0 firmware update released on June 9, 2026," specifically when updating via Lumix Lab. According to the warning, the ability to update using the app should be turned off, but if for some reason it still lets you do it, you should probably cancel the operation.
While there are several people who say they successfully updated their camera with Lumix Lab, there are also a few reports on social media from people experiencing major issues after doing so, with their cameras rendered essentially unusable.
Panasonic says you can still update the camera's firmware by using a computer to download the file, then copying it onto a memory card. It also says it's working to fix the issue so people will be able to update their camera's firmware with Lumix Lab in the future.
