A massive wave of pager explosions across Lebanon and Syria beginning at 3:30 pm local time today killed at least 11 people and injured more than 2,700, according to local officials. Many of the injured appear to be Hezbollah members, although a young girl is said to be among the dead.

Anonymous officials briefed on the matter are now describing it as a supply chain attack in which Israel was able to hide small amounts of explosives inside Taiwanese pagers shipped to Lebanon. The explosive was allegedly triggered by a small switch inside the pagers that would be activated upon receiving a specific code. Once that code was received, the pagers beeped for several seconds—and then detonated.

New York Times reporters captured the chaos of the striking scene in two anecdotes:

Meta yesterday announced a ban on Russian state media outlets RT (formerly Russia Today) and Rossiya Segodnya, taking action three days after the US government imposed sanctions on the outlets for covert influence activities.

"After careful consideration, we expanded our ongoing enforcement against Russian state media outlets: Rossiya Segodnya, RT and other related entities are now banned from our apps globally for foreign interference activity," Meta said in a statement provided to Ars. Meta is the owner of Facebook, Instagram, WhatsApp, and Threads.

Meta already blocked RT and Rossiya Segodnya's Sputnik network across Europe in March 2022, following a ban imposed by European Union government officials. YouTube blocked the channels worldwide. At the time, Vladimir Putin's government was telling Russian media outlets not to call the invasion of Ukraine "an attack," "invasion," or "declaration of war."

Fans of ultra-viral mobile gaming hit Flappy Bird who were stunned by the game's sudden removal from the iOS App Store 10 years ago were probably even more stunned by last week's equally sudden announcement that Flappy Bird is coming back with a raft of new characters and game modes. Unfortunately, the new version of Flappy Bird seems to be the result of a yearslong set of legal maneuvers by a crypto-adjacent game developer intent on taking the "Flappy Bird" name from the game's original creator, Dong Nguyen.

"No, I have no related with their game. I did not sell anything," Nguyen wrote on social media over the weekend in his first post since 2017. "I also don't support crypto," Nguyen added.

No, I have no related with their game. I did not sell anything.
I also don't support crypto.

"Flappy Bird was designed to play in a few minutes when you are relaxed," Nguyen said in a 2014 interview after removing the game from mobile app stores. "But it happened to become an addictive product. I think it has become a problem. To solve that problem, it’s best to take down Flappy Bird. It's gone forever."

Vincent van Gogh's most famous painting is The Starry Night (1889), created (along with several other masterpieces) during the artist's stay at an asylum in Arles following his breakdown in December 1888. Where some have seen the swirling vortices of the night sky depicted in Starry Night as a reflection of van Gogh's own inner turmoil, physicists often see a masterful depiction of atmospheric turbulence. According to a new paper published in the journal Physics of Fluids, the illusion of movement in van Gogh's blue sky is also due to the scale of the paint strokes—a second kind of "hidden turbulence" at the microscale that diffuses throughout the entire canvas.

“It reveals a deep and intuitive understanding of natural phenomena,” said co-author Yongxiang Huang of Xiamen University in China. “Van Gogh’s precise representation of turbulence might be from studying the movement of clouds and the atmosphere or an innate sense of how to capture the dynamism of the sky.”

As previously reported, in a 2014 TED-Ed talk, Natalya St. Clair, a research associate at the Concord Consortium and coauthor of The Art of Mental Calculation, used Starry Night to illuminate the concept of turbulence in a flowing fluid. In particular, she talked about how van Gogh's technique allowed him (and other Impressionist painters) to represent the movement of light across water or in the twinkling of stars. We see this as a kind of shimmering effect, because the eye is more sensitive to changes in the intensity of light (a property called luminance) than to changes in color.
