AI Model Beats Turing Test, Raising Concerns About Human-Like Intelligence

U.S. stock markets experienced their worst one-day sell-off since 2020 on April 3, 2025, driven by President Trump’s announcement of steep new tariffs dubbed "Liberation Day," which sent the Dow Jones Industrial Average tumbling nearly 1,700 points, or 4%. The Nasdaq Composite fell approximately 6%, while the S&P 500 dropped nearly 5%, marking a historic downturn for the indices. The tariffs, which apply a baseline rate of 10% on all U.S. trading partners and escalate to higher rates for so-called "bad actors," raise the effective tariff level in the U.S. to the highest seen in over a century, affecting 185 countries. Analysts from Oxford Economics warned that the U.S. economy is now "dangerously vulnerable" to recession, as fears mount over retaliatory measures and their potential to curtail economic growth. Tech stocks led the declines, with Apple shares dropping over 9% amid concerns about disrupted supply chains linked to Chinese components. Overall, the market wipeout resulted in the "Magnificent Seven" tech stocks losing over $900 billion in value, alongside significant hits to other sectors, reflecting deepening uncertainty in global economic conditions.

A 6-month-old baby girl tragically died following a dog attack in Baytown, Texas, on April 1, according to local reports. The attack took place in an apartment complex on E. James Avenue just after 3:45 p.m. Witnesses reported that the child's mother, who had recently celebrated her daughter's birthday and moved into the complex, was seen seeking help from neighbors. One neighbor recounted the distressing scene, stating, “She knocked on my door, baby in hand. Blood was everywhere. The mother was just devastated,” as quoted by KPRC. Emergency services were called, and the infant was transported to a nearby hospital, where she later died from her injuries, as reported by KHOU. Baytown Animal Services responded to the scene and took two pit bull mixes into custody, including a 1-year-old red-collared pit bull mix believed to be responsible for the attack. Officials indicated that the family has agreed to surrender the dog for euthanasia. The second dog, a blue-collared pit bull mix, was not involved in the incident and was secured in a kennel at the time of the attack.

Xiaofeng Wang, a prominent cybersecurity professor at Indiana University, and his wife, Nianli Ma, have mysteriously vanished following FBI raids at their residences in Bloomington and Carmel, Indiana. Local news reports indicate that agents spent several hours searching the homes, removing boxes of evidence and questioning individuals present. The FBI confirmed it conducted court-authorized activities but has not commented further on the nature of the investigation, according to a spokeswoman. In addition to the raids, both Wang's and Ma's profiles were quietly removed from the Indiana University website, raising concerns among colleagues. Wang, who has a significant track record in cryptography and data privacy, has reportedly not been heard from for at least two weeks, prompting growing unease within the academic community. Matthew Green, a fellow researcher, described the events as “not normal” on social media. Officials from the university did not provide clarity on their employment status or the circumstances leading to the FBI's actions. The couple's current whereabouts remain unknown.
