Big Tech accused of stonewalling European social media researchers

25 July 2026 at 11:45

In the final weeks before Romania’s presidential vote in November 2024, TikTok accounts that had previously spent years posting about manicures or fashion suddenly started promoting a little-known politician named Calin Georgescu.

His posts, espousing hard-line views on immigration and anti-Semitic tropes, were viewed 120 million times before the vote. Georgescu, who had previously been polling in the single digits, stunned observers by winning the election’s first round with 23 percent of the vote.

In the Netherlands, Adriana Iamnitchi was watching closely. As chair of computational social sciences at Maastricht University, she leads the research into disinformation campaigns. She wanted to know how pro-Georgescu content was being monetized on TikTok through hidden influencer marketing and livestreamed political content.

AI companies, including Nvidia and Mistral, urge policymakers to avoid broad restrictions on open-weight AI models as Washington debates responses to Chinese AI and alleged model distillation.

Rocket Report: Lightning strikes in China; Starship launch on deck

24 July 2026 at 15:34

Welcome to Edition 9.04 of the Rocket Report! We've had to wait an extra week for SpaceX to get its 13th Starship test flight off the ground. A last-second abort on July 16 led engineers to roll the booster back to its hangar in South Texas to swap out engines. Starship is now back on the launch pad. Liftoff is set for Friday evening. A flawless launch and reentry will put SpaceX on the cusp of an orbital flight later this year. Ars will have a comprehensive recap story after the completion of the test flight.

Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

India's first private rocket reaches orbit. Indian space officials celebrated the debut flight of Skyroot Aerospace’s Vikram-1 rocket, India’s first fully commercial satellite launcher, as a “grand success” Saturday after an on-target climb into a 280-mile-high orbit following liftoff from an island spaceport in the Bay of Bengal, Ars reports. The Vikram-1 lifted off from India’s primary spaceport on Sriharikota Island around midday local time. The launch was delayed more than a half-hour to resolve a last-minute technical problem. The countdown resumed, culminating in the command to ignite Vikram-1’s solid-fueled first stage booster to propel the rocket off the launch pad.

WhatsApp começa a liberar novo design para bolhas de mensagens no iOS

24 July 2026 at 13:15

Após um período em desenvolvimento, o WhatsApp começou a liberar um novo design para as bolhas de mensagens para testadores e alguns usuários da versão estável do seu aplicativo para iOS.

Como mostra a comparação abaixo, divulgada pelo WABetaInfo, as bolhas agora contam com cantos mais arredondados em relação à interface anterior — o que dá a elas uma aparência bem mais moderna.

Outra mudança pode ser vista especialmente nas mensagens de mídia trocadas em chats individuais, que deixaram de ter uma borda em volta de seu conteúdo e apresentam exclusivamente a foto ou o vídeo em questão.

Mensagens de mídia encaminhadas ou enviadas em grupo ainda mostram uma borda exclusivamente na parte superior — com o rótulo de encaminhamento ou a identificação de quem as enviou, respectivamente.

Links enviados com pré-visualização, por sua vez, apresentam a borda apenas na parte inferior, para abrigar o indicador de envio/recebimento/leitura.

Apesar de bem simples, essa será mais uma mudança que dará uma maior modernização à interface do app — especialmente nas bolhas das mensagens, que mantêm o mesmo estilo há muito tempo.

How Fast Is the Universe Really Expanding?

One of the biggest mysteries in cosmology seems to keep getting bigger. Astronomers have known since the 1930s that the universe is expanding, but in the 1990s, the discovery that this expansion is accelerating rather than slowing down came as a huge shock to the field. Something had to be driving that acceleration, and dark energy was proposed as the cause. What began as a seismic shock in…

India's first privately developed rocket reaches orbit on dramatic debut launch

19 July 2026 at 23:11

Indian space officials celebrated the debut flight of Skyroot Aerospace's Vikram-1 rocket, India's first fully commercial satellite launcher, as a "grand success" Saturday after an on-target climb into a 280-mile-high orbit following liftoff from an island spaceport in the Bay of Bengal.

The Vikram-1 lifted off from India's primary spaceport on Sriharikota Island at 1:35 am EDT (06:35 UTC) Saturday, around midday at the launch base along India's southeast coast. The launch was delayed more than a half-hour to resolve a last-minute technical problem. The countdown resumed, culminating in the command to ignite Vikram-1's solid-fueled first stage booster to propel the rocket off the launch pad.

Vikram-1 is modest in size compared to India's larger workhorse rockets. Skyroot's rocket stands about 72 feet (22 meters) tall, with the capability to place payloads of up to 770 pounds (350 kilograms) into low-Earth orbit. This makes Vikram-1 somewhat larger than the Electron launch vehicle developed by Rocket Lab, the world's most successful dedicated small satellite launcher.

HP fined 1.4 billion rupees for “cartelization” of ink cartridges, toner, PCs

16 July 2026 at 23:02

The Indian government has fined HP India and its partners a total of 1.4 billion rupees (about $14.4 million) for working with reseller partners in the “cartelization” of computers, ink cartridges, and toner.

The Competition Commission of India (CCI) said this week that it found HP India had colluded with some channel partners to drive up the cost of bids for government contracts for computers, as well as for selling ink cartridges, toner, and other printing supplies, including graphic and digital manufacturing supplies.

It said that HP was aiming to outcompete other OEMs and discourage resellers from selling “counterfeit” ink and toner.
