O AirPlay é a maneira mais fácil de transmitir conteúdos de um iPhone, iPad ou Mac para smart TVs compatíveis ou Apple TVs — sejam eles vídeos ou músicas.
Indo mais além dos aplicativos nativos da Apple que permitem isso, há os apps de terceiros que também podem suportar a tecnologia. Um deles é o TikTok, rede social de vídeos curtos. A partir de qualquer post, basta alguns toques para transmitir os conteúdos da rede no aparelho compatível.
Antes de mais nada, certifique-se de que o TikTok possui acesso à rede local. Para isso, abra os Ajustes (Settings), toque em “Apps” e em “TikTok”. Depois, marque a chave ao lado de “Rede Local”.
Abra então o TikTok e localize a postagem que deseja enviar. Mantenha o dedo pressionado por alguns segundos em cima dela, role pela lista e toque em “Transmitir”.
A Apple parece estar preparando seus sistemas para a nova leva de produtos que será lançada em breve. A menos de 24 horas do evento “Surprise and shine” (“Surpreendente e brilhante”), a empresa adicionou nada menos que 37 novos identificadores de hardware ao seu backend, abrangendo iPhones, iPads, Macs, Apple Watches e outros dispositivos.
A descoberta foi feita por Aaron Perris. No X, ele compartilhou todos os identificadores, sendo sete deles relacionados a iPhones.
A bunch of upcoming Apple device identifiers have been found on Apple’s backend. Interestingly, there are 7 iPhone models listed. We only know of 6.
O número chama atenção pois, até o momento, os rumores dão conta de seis modelos compondo a futura linha: “iPhone 18 Pro”, “iPhone 18 Pro Max” e “iPhone Ultra”, além dos “iPhone 18”, “iPhone Air 2” e “iPhone 18e” — os três últimos, segundo as notícias, só serão lançados no ano que vem.
Isso, porém, não significa necessariamente que a Apple esteja preparando um sétimo iPhone do qual nunca ouvimos falar. O identificador pode muito bem ser simplesmente uma variante de um dos modelos já esperados — como, por exemplo, uma configuração específica do “iPhone Ultra” destinada à China.
Além dos iPhones, a lista inclui nove identificadores de Macs, oito de iPads, nove de Apple Watches, um de Apple TV e três associados à categoria “HomeAccessory”, utilizada internamente pela Apple para produtos domésticos.
Lembrando que, no evento de amanhã, a Apple muito provavelmente lançará produtos como o “Apple Watch Series 12”, o “Apple Watch Ultra 4”, uma nova geração da Apple TV e, quem sabe, o aguardado hub inteligente para a casa — além dos iPhones, é claro. Novos Macs (como um iMac com chip M6 e a estreia dos “MacBooks Ultra”) e iPads (como o iPad mini com tela OLED), contudo, não são esperados para esta semana.

James Frith says patients may be less willing to share data as new figures show a rise in opt-outs
Concern is being raised about Palantir’s work with the NHS as new figures showed tens of thousands of patients have withdrawn their data from use in research projects.
James Frith, the health innovation minister, said he was worried about “mistrust” of the US defence and health tech company and “the impact it could have on people’s willingness to share data with the NHS”.
Smartphone longevity didn't used to matter. In the past, before you could wear out or break a phone, there was always some shiny new thing to buy. Today, we expect our smartphones to go the distance, but they've also become less repairable and, in many cases, more fragile. Fairphone, a Dutch smartphone maker that has just entered the US market, thinks about phones differently.
The new $650 Fairphone Gen 6+ is designed both for longevity and easy repairability. There are trade-offs to this approach if you're used to the standard glass and aluminum sandwiches filled with glue, gaskets, and teeny-tiny screws. But the drawbacks could be worth it for the right buyer. Fairphone CTO Chandler Hatton told Ars that Fairphone's goal is to provide a compelling mobile experience while also enabling the user to "fully own" their device. At the end of the day, this is what a lot of people say they want in a smartphone.
Take it apart, put it back together
These days, Google, Samsung, and Apple support phones with software updates for the better part of a decade, but will the hardware last that long? And what happens when it needs a repair? You may be out of luck or out a lot of money, but Fairphone prioritizes the self-repair experience.
Relocation coincides with proposed laws that opponents say would entrench power of US tech billionaires in country
Dozens of protesters converged on Peter Thiel’s mansion in Buenos Aires this week after a congressional session raised questions about the billionaire’s presence in the country.
In white masks, they held signs saying “Peter Thief” and “No to the Peter Thiel law” in front of the wrought-iron gates of the $12m (£8.9m) residence, which Thiel bought in April as he moved his family to Argentina.
For thousands of years, one of prehistoric Europe’s most lasting testaments to monumental architecture has stood along the coast of Brittany.
Hidden among the famous Neolithic monuments in this region of northwestern France is evidence of an earlier landscape—one whose ancient and enormous “standing stones” were occasionally broken apart, later to be reused by builders from successive ages.
France’s famous Locmariaquer megaliths include the Table des Marchands passage grave, the Er-Grah tumulus, and the extraordinary Grand Menhir Brisé, or Great Broken Menhir. Together, these ancient monuments preserve generations of ancient Europe’s monumental construction.
Yet among the most intriguing discoveries from this region are those related to the Table des Marchands itself. Specifically, the enormous, decorated capstone featured with this monument was once part of something else, and its remains preserve evidence of a much earlier massive freestanding stone monument.

A Neolithic Jigsaw Puzzle
During work at the passage tomb of Gavrinis, located on an island roughly four kilometers away, a chance discovery eventually led archaeologists to a breakthrough.
Several decades ago, archaeologist Charles-Tanguy Le Roux had been examining the once-concealed upper surface of the massive capstone, which covers the ancient tomb structure’s main chamber. During his inspection, it became evident to Le Roux that engravings on its surface appeared to be something more than just unique designs etched onto the capstone; they were a continuation of other designs found at the Table des Marchands.

Additional pieces of this Neolithic jigsaw puzzle began presenting themselves nearby, and once reconstructed, the long-separated slabs now seemed to indicate that they had once formed portions of a single monumental, decorated stone, once measuring an astounding 14 meters in length and weighing close to 100 tons.
Over time, fragments of the original monument had apparently been separated and incorporated into different later structures—a discovery that offered evidence of megalithic recycling in the ancient world.
The recycling of monumental ancient fixtures was common in the ancient world. Well-known examples include the reuse of stone blocks from construction sites in Egypt for later monuments. Also, a recent discovery in Turkey revealed that a massive, ancient Lydian-era statue was later broken into two pieces and used as part of a roadway during the Roman era.

An Earlier Monumental Landscape
At the Table des Marchands, the reconstructed stone had been adorned with engravings that included depictions of ancient bovines, as well as symbolic motifs. Originally, it is believed this megalithic marvel once stood as part of an earlier monumental complex in the area, which was toppled and fragmented at some point.
That earlier landscape included the Grand Menhir Brisé, or “The Great Broken Menhir,” a massive megalithic stone that once towered over the site, erected by ancient engineers around 4,700 BC. At the time this megalith stood upright, it measured almost 70 feet in height and weighed some 330 tons, making it one of the most extraordinary engineering achievements known from Neolithic Europe.

Sometime around 4,000 BC, the massive stone megalith toppled over, and today its remains are preserved in four large broken pieces adjacent to the Table des Marchands. Archaeologists believe that it may have once belonged to an alignment of large standing stones erected around the fifth millennium BC.
With time, the large standing stones were brought down, and while ending an ancient megalithic tradition, at least some portions of these ancient monuments saw later reuse in newer monuments. Fragments of these much earlier, highly decorated stones made their way into the nearby tombs, which can still be seen in these monuments today—including the famous capstone at the Table des Marchands, and the massive slab at Gavrinis.
Why Dismantle a Monument?
The exact reason these enormous ancient monuments were dismantled remains unknown, although archaeologists have proposed a few theories.
Such reuse may have been entirely practical and seen as a means of borrowing from available resources present in the landscape when a later need arose. Another possibility is that there may have been a deeper significance to such practices, whereby the addition of fragments from earlier monuments into newer ceremonial or funerary structures may have imbued these newer structures with the essence of the past.
Doing so may have allowed Europe’s ancient Neolithic engineers to preserve connections to their ancestors and establish continuity between past and present as newer monuments were constructed.
Alternatively, it may have been that instead of trying to preserve ancient traditions, later builders who reused components from these monuments may have been deliberately rejecting earlier social or religious ideas by using smashed remnants from those periods in newer constructions.
Amid such questions, the enigmatic capstone of the Table des Marchands offers a unique look at Europe’s remarkable prehistoric engineering, surviving as a fragment of older times that found new purpose in one of Neolithic Brittany’s most intriguing ancient monuments—and pieces to an ancient puzzle that will likely remain unsolved.

Casimir Inc., a technology startup that made headlines with its controversial vacuum energy chip, MicroSparc, has received a financial award from the United States Air Force Research Lab’s SpaceWERX to advance the technology toward practical defense applications.
According to a company statement, the Phase I award, part of the Department of the Air Force’s (DAF) broader Small Business Technology Transfer (STTR) program, will fund Casimir to explore the technical viability of its vacuum energy chip, which The Debriefpreviously revealed exclusively.
Although a Phase I award does not guarantee future financial support, the new ‘proof-of-concept and potential’ award could put Casimir in line for future Phase II and Phase III awards from SpaceWERX, depending on the success of this phase.
The company told The Debrief that Casimir’s goal “remains full commercialization of MicroSparc by 2028.”
SpaceWERX Award Will Assess Feasibility of Casimir’s MicroSparc Technology
According to the SpaceWERX site, STTR Phase I grants are awarded to companies to “prove the technical merit and commercial viability of your innovative idea.”
“SpaceWERX manages the United States Space Force’s Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs, awarding contracts to startups and small businesses developing technologies with commercial and defense applications that strengthen the U.S. defense industrial base since 2019,” the SpaceWERX site explained.
Although Casimir did not provide financial or timeline specifics, SpaceWERX guidelines indicate these awards typically range from $75K to $180K and last three to 12 months. As an “Open Topic” award, Casimir’s work will also include what the SpaceWERX site describes as “a critical customer discovery phase.”
The company said the new award will allow the team to focus on “developing Casimir’s fully independent solid-state generator to address the most pressing challenges in the Department of the Air Force (DAF).”
“The Phase I work is focused on validating Casimir’s independent solid-state generator design against DAF requirements for systems operating in remote or hard-to-service environments,” a company spokesperson told The Debrief. “This is especially notable because it expresses a desire and need for Casimir’s tech in mission-critical environments.”
“The Underlying Physics” Are Not New
Former NASA Eagleworks researcher and Casimir co-founder Dr. Harold G. “Sonny” White later pursued research involving engineered Casimir cavities at the Limitless Space Institute, including work supported by the Defense Advanced Research Projects Agency (DARPA).
“This concept became a central part of our DARPA Defense Sciences Office (DSO) research effort at the Limitless Space Institute, where DARPA funded early theoretical and experimental investigations into custom Casimir cavity structures and their interaction with the quantum vacuum,” White previously told The Debrief.
Although the company previously said it already has functioning prototypes, many scientists have challenged the technology’s validity, with some labeling the MicroSparc a “perpetual motion” machine that violates the laws of physics. When describing the concept to The Debrief, Dr. White seemed to anticipate those criticisms, noting that MicroSparc takes advantage of established quantum physics principles, clarifying that the technology does not violate basic physics principles.
“The underlying physics itself is not new,” White told The Debrief.
Instead, the former NASA scientist noted that the Casimir effect “has been part of established quantum mechanics since the mid-20th century and has been experimentally verified by laboratories around the world.” MicroSparc, he explained, is based on that science.
MicroSparc, White argues, builds on that established physics, although the company’s much more consequential claim—that its device can produce continuous usable electrical power from the quantum vacuum—has not been independently demonstrated.
“In our device, the quantum vacuum outside the cavity walls vigorously stimulates electrons in the wall atoms,” Dr. White previously told The Debrief. “Occasionally, an electron will quantum tunnel from the wall to one of the central pillars.”

For clarification, quantum tunneling is a well-established quantum phenomenon in which a particle has a finite probability of crossing an energy barrier that it could not overcome according to classical physics. The effect has been repeatedly demonstrated experimentally and underlies technologies ranging from scanning tunneling microscopes to semiconductor devices.
“Once inside the protected cavity, the environment is far quieter, (so) the probability of the electron tunneling back to the wall is orders of magnitude lower,” White told The Debrief.
White said this phenomenon creates a one-way flow of electrons toward the pillars, a process he compared to “a kind of quantum ratchet.” By fabricating millions of these microscopic cavities on a single chip, White said his team was able to produce “a continuous electrical current drawn from the quantum vacuum.”
Refining the Vacuum Energy Concept for a Fully Independent Generator
When discussing the significance of the award, especially given the controversial nature of vacuum energy concepts, the company told The Debrief that the award is “a signal to the market and community that this tech is pivotal and up-and-coming…now with gov’t resources.”
Dr. White agreed, noting that “This Phase I award is an important step in exploring how Casimir’s solid-state power technology could support national security missions where persistent, reliable power is essential.”
“As a producer of quantum energy technology, this project will allow the Casimir team to refine the concept for a fully independent generator while working with potential customers to better understand the requirements of systems operating in austere and difficult-to-service environments.”
Moving forward, the company told The Debrief that its goal remains targeting commercial availability of Casimir’s MicroSparc chip by 2028, “positioning the company to disrupt the ultra-low-power electronics sector.”
“The DAF began offering the Open Topic SBIR/STTR program in 2018, which expanded the range of innovations the DAF funded, and now, in August 2026, Casimir will continue its journey to create and provide innovative capabilities that will strengthen the national defense of the United States of America,” the company’s statement explained.
“Much of modern electronics is constrained by batteries, charging cycles, wiring, maintenance, or environmental limitations,” Dr. White told The Debrief. “If this technology scales successfully, its long-term implications could extend from ultra-low-power sensors and consumer electronics to remote infrastructure, defense systems, and eventually space applications, where persistent power is especially valuable.”
Although Phase I STTR awards are a necessary step toward larger Phase II and Phase III awards, which are designed to take emerging technologies proven in Phase I to the market, the company told The Debrief, “it’s way too soon” to realistically think about those steps, while acknowledging the possibility “down the line.”

Amazon wants to grow its Prime Air delivery drone service sixfold to reach nearly 500 cities and towns across the United States by the end of 2026. The planned expansions from Amazon and its rivals could make the convenience of delivery drone services available to tens of millions more people in the coming months—but will also test more communities’ tolerance for increased noise from daily drone flights.
On August 19, Amazon announced it would soon launch Prime Air in the metropolitan areas of Chicago; Cleveland; Atlanta; Syracuse, New York; and Boise, Idaho, with more to come later in the year. Each Prime Air site offers delivery drone service within an area of about 175 square miles, with delivery times ranging from half an hour to an hour.
Prime Air already operates out of Amazon warehouses in 10 cities across seven states. Those include primarily suburban neighborhoods of Phoenix; Tampa; Kansas City; Omaha, Nebraska; Baton Rouge, Louisiana; Detroit; Houston; and San Antonio, Dallas, and Waco, Texas.
