Meta Removes Ads For Social Media Addiction Litigation

Meta has started removing ads from law firms seeking clients for social media addiction lawsuits, just weeks after a jury found Meta and YouTube negligent in a landmark case involving harm to a young user. "Lawyers across the country now are seeking new plaintiffs, in the hopes of bringing a class action lawsuit that could result in lucrative verdicts," reports Axios. From the report: Axios has identified more than a dozen such ads that were deactivated today, some of which came from large national firms like Morgan & Morgan and Sokolove Law. Almost all of them ran on both Facebook and Instagram. Some also appeared on Threads and Messenger, plus Meta's Audience Network -- which distributes ads to thousands of third-party sites. One such ad read: "Anxiety. Depression. Withdrawal. Self-harm. These aren't just teenage phases -- they're symptoms linked to social media addiction in children. Platforms knew this and kept targeting kids anyway." A few of the ads still remain active, including some that were posted earlier today. "We're actively defending ourselves against these lawsuits and are removing ads that attempt to recruit plaintiffs for them," a Meta spokesperson said in a statement. "We will not allow trial lawyers to profit from our platforms while simultaneously claiming they are harmful."

Particles Seen Emerging From Empty Space For First Time

Longtime Slashdot reader fahrbot-bot shares a report from NewScientist: According to quantum chromodynamics (QCD) -- widely considered to be our best theory for describing the strong force, which binds quarks inside protons and neutrons -- even a perfect vacuum isn't truly empty. Instead, it is filled with short-lived disturbances in the underlying energy of space that flicker in and out of existence, known as virtual particles. Among them are quark-antiquark pairs. Under normal conditions, these fleeting pairs vanish almost as soon as they appear. But if enough energy is injected into a vacuum, QCD predicts they can be promoted into real, detectable particles with measurable mass. Now, the STAR collaboration -- an international team of physicists working at the Relativistic Heavy Ion Collider in Brookhaven National Laboratory in New York state -- has observed this process for the first time. The team smashed together high-energy protons in a vacuum, producing a spray of particles. Some of these particles should be quark-antiquark pairs pulled directly from the vacuum itself, but quarks can never exist alone and immediately combine into composite particles. Quarks and antiquarks are born with their spins correlated -- a shared quantum alignment inherited from the vacuum. The researchers found that this link persists even after the quarks and antiquarks become part of larger particles called hyperons, which decay in less than a tenth of a billionth of a second. Spotting these spin-aligned hyperons in the aftermath of the proton collisions allowed the researchers to confirm that the quarks within them came from the vacuum. The findings have been published in the journal Nature.

US Fertility Rate Falls To All-Time Low

An anonymous reader quotes a report from NPR: Women in the U.S. gave birth to roughly 710,000 fewer children last year compared with the nation's peak in 2007, according to preliminary data released (PDF) this week by the Centers for Disease Control and Prevention. Lead researcher Brady Hamilton, a demographer with the CDC's National Center for Health Statistics, said the latest one percent drop in "general fertility" from 2024 to 2025 is part of a long-running downward trend. "Since 2007, there's been a decline in the general fertility rate [in the U.S.] of 23%," Hamilton told NPR. The impact of that change in real numbers is sizable: In 2007, there were 4,316,233 babies born. Last year, even though the nation's population as a whole is larger, there were only 3,606,400 newborns. There's no consensus over why women and couples have shifted their behavior so significantly. Some experts point to economic factors, others say cultural influences, and better access to education and contraception for women are driving the change. "We're seeing big drops in fertility rates for young women, teenagers and women in their 20s," said economist Martha Bailey, head of the California Center for Population Research at the University of California, Los Angeles. "What's not yet clear is whether or not those same women will go on to have children later on." "People are having the number of children they want and that they can afford at a time that makes the most sense for them," she said. "What I don't think anyone is in favor of is a Handmaid's Tale type policy regime, where we're trying to talk families into having children they don't want." One silver lining in the data is the 7% decline in teen pregnancies in 2025. Bianca Allison, pediatrician and associate professor at the University of North Carolina School of Medicine, said: "What is actually affecting the birth rates are likely lower rates of teen pregnancy overall, which is in the context of higher use of contraception and lower sexual activity for youth, and then also continued access to abortion care."
