Com a crise de componentes e os preços dos dispositivos da Valve nas alturas, a companhia revelou oficialmente que nada disso impactará o lançamento do Steam Deck 2. Isso significa que os valores do portátil atual de US$ 789, do Steam Frame de US$ 1.059 e do Steam Machine por US$ 1.049 não são um novo padrão.

Ao IGN, o desenvolvedor da companhia, Pierre-Loup Griffais, revelou que os planos que já têm sobre o hardware “não mudaram muito” em relação às altas nas memórias RAM e armazenamentos, assim como datas. Claro, a fala carrega um “porém”: o aparelho não será lançado em breve, possivelmente após a conclusão dos aumentos.

“Falamos antes sobre como queremos garantir que haverá um salto de desempenho para algo similar ao ‘futuro Steam Deck’, acredito que continuamos a seguir o mesmo caminho”, afirmou o porta-voz.

O que ele realmente quer dizer? Eles só trarão um novo console portátil ao mundo quando notarem uma exigência maior por um produto de alta performance. Essa situação pode ocorrer apenas no instante em que esta crise chegar ao fim, logo eles não enxergam a forma que todo o caos nos hardwares pode impactar os negócios da Valve para o modelo.

A empresa já revelou trabalhar no Steam Deck 2, contudo é possível que o dispositivo ainda esteja em estágio embrionário. Ou seja, há chances de que já saibam como fazê-lo dar certo, no entanto podem aguardar por uma queda de valores e a possibilidade de produzi-lo em grande escala sem prejuízos.

Nada mudou para a Valve

Griffais também explica que os planos seguem iguais aos que foram declarados no passado. Para ele, “no que temos trabalhado, conforme a experiência dos jogadores progride e o que o produto pretende construir, os objetivos são bem similares”. 

A declaração serve para acalmar o público que não deseja ver o Steam Deck 2 a preços estelares. Com um acréscimo expressivo no custo de vários hardwares, todos os produtos da sua linha tiveram de ser vendidos a preços elevados. 

No entanto, o cenário pode não ser um problema no momento em que o console portátil for lançado. Se levarmos em conta que as mudanças podem ocorrer apenas entre 2029 e 2030, talvez tudo isso já seja uma história que ficou para trás. 

Enquanto a Valve segue a passos lentos com o Steam Deck, quem trabalha com emulação surpreende cada vez mais com um salto surreal: emulador de PS5 faz Demon's Souls ir de 1 a 30 FPS em uma semana.

My dentist, Dr Albora, told me I needed a new tooth. He made me bite down on a U-shaped tray filled with polyether, an elastomeric material that’s been used in dentistry for decades. I tried not to gag while the gooey stuff set. Albora then waggled it off and sent the imprint to a company on Long Island that makes false teeth. But as my tooth’s colouring was unusual, Dr Albora said I had to go there myself.

A week later I drove to Marotta Dental Studio, where Igor Binshteyn sat me in a chair, lifted my lip and inspected a tooth to the side of my upper jaw. He was helping to fabricate its replacement and needed to get the exact colour.

As Binshteyn finished, I remarked teasingly on the company’s car park, which was chock full. Do you need that many people to make false teeth? What could possibly be involved to make things smaller than the nail on my little finger?

Binshteyn laughed. “Follow me”.

He opened a door to a huge undivided warehouse-like space about 1200 square metres in size. Some 50 people were working at lines of tables where the steady hum of conversation was punctuated by the noise of ovens, lathes and grinding machines; imagine the sounds of a metalworking shop in a busy train station.

“Do you want a tour?” Binshteyn said.

Of course I did.

Open wide

My tour guide was Marotta’s vice-president, Steven Pigliacelli, who teaches prosthodontics at New York University. A prosthodontist is a dental specialist who has completed dental school and, in the US, has had at least three additional years of advanced training to focus on restoring and replacing missing or damaged teeth. As I learned, prosthodontists must practice materials science.

The lab has two paths for making teeth, Pigliacelli explained, each with different materials and methods. The first is known as “porcelain-fused-to-metal”, or PFM. It begins with technicians applying gypsum – hydrated calcium sulphate – to create stone replicas of the jaw and teeth from the impressions given to them by dentists such as Albora.

Gypsum has different coefficients of expansion for different dental purposes, and textbook formulas give the amounts of liquid for each kind. But Marotta employees found that tiny amounts of water must be added or subtracted to the gypsum to compensate for things like humidity and temperature before the gypsum is used. “It took us months,” Pigliacelli explained, “to realize that how it’s shipped, how it’s stored, what season it is – all these affect the material.”

I watched as a technician sectioned a stone jaw replica to cut out a tooth, turn it into a master model called a die, and test it in an articulator that mimics jaw movements. I saw another wax that die, use a lost wax technique to create a solid gypsum frame, and cast a silver-palladium alloy. That creates the metal inner core for the tooth, called a coping, which is shaped and finished before porcelain is applied. Porcelain is baked onto the coping in another area of the lab.

“The metal and porcelain need closely matched coefficients of thermal expansion or the porcelain can separate from the metal,” Pagliacelli told me. “Every once in a while a company tells us ‘We’ve got this really cool new alloy!’, but we need to match the coefficients of expansion in the ceramic material. We’re working with sensitive materials for sensitive applications, and we have to experiment with and adapt them. This stuff about materials you don’t learn in school but work out in the lab.”

Smile for the camera

The second path to making a tooth involves scanning the teeth rather than waxing a die. The electronic files are worked on in the computer, printed out, reworked and rescanned, and milled by a CAD machine using materials such as zirconia – nicknamed “ceramic steel” – and EMAX, a lithium disilicate glass-ceramic. Zirconia is extremely hard and used for teeth that endure heavy grinding forces, while EMAX is more aesthetically pleasing and often used for front teeth.

“So we have two parallel paths, PFM and digital scans”, Pigliacelli said. “It’s usually a personal choice of the dentist”. But external pressures are driving a move away from PFM, he said. Five years ago the price of palladium – a key component of the PFM alloy – soared as it was increasingly used in devices to reduce auto and other emissions. “That’s cut down on the PSM market.”

In another corner of the lab I ran into Binshteyn again, who was using different porcelains and ceramic stains to create colours. “Teeth are not a solid colour,” he said, “but vary in shade from reddish near the gum line to lighter colours toward the biting edge. They also vary in translucency.” (Check this out yourself.) Furthermore, the colour of a tooth must match not its neighbours but the corresponding tooth on the other side of the mouth. To make a natural-looking tooth, Igor picks out a base colour and then layers in shades of porcelain.

As my lab tour went on, Pigliacelli showed me different materials for different applications. One challenge is making teeth for a person with bulimia, whose acidic oral environment can corrode dental materials. Other challenges arise with people who have had failed implants, or temporomandibular joint – or TMJ – a disorder involving jaw joints and muscles.

On the way out I met Lenny Marotta, Pigliacelli’s brother-in-law, who had founded Marotta Studio in 1981. Marotta is fascinated by the history of dental materials, which include bone, ivory, wood, gold and silver. He showed me his collection of early prosthodontic instruments, including milling machines, furnaces, hammers and air compressors.

Later, Marotta also pointed out a strange-looking oven. “That’s for processing vulcanite, a hardened rubber material widely used for dentures before modern plastics.” But he’s been unable to find a museum interested in old prosthodontic stuff. “Nobody knows we exist,” he complained.

The critical point

I’d assumed that materials science was required to make prosthetic teeth biocompatible, corrosion resistant, and able to withstand mechanical motions such as crushing, biting and grinding. I also knew that teeth have to be made economically enough to be widely available, aesthetic enough to be desirable, and versatile enough to withstand a variety of oral environments.

But I had no idea how much materials science was required to bring all these properties together.

Back in his office, Dr Albora installed the tooth and handed me a mirror. I had to pull up my lip to see it way on the side of my mouth. “I’d have to smile before somebody notices it,” I complained. “Well,” he said, “that’s for just in case you do.”

Apple has been working on plans for an enterprise server using its own chips that could incorporate networking equipment from Nvidia, people familiar with the project said, as the Mac maker looks to capitalize on surging interest in its computers for AI.

Apple has been developing the server with plans to sell it to AI developers, other businesses and governments, the people said. The product under consideration would come in two versions—a smaller one with two of Apple’s planned M8 Ultra chips clustered together and a bigger one with four M8 Ultra chips. The M-series Ultra chips are Apple’s highest-performance chips and power products including the Mac Studio.

Since February 2026, the United States Department of War (DOW), under the direction of President Donald Trump, has released an unprecedented number of documents, videos, and firsthand witness accounts detailing the United States’ extensive history of encounters with unidentified anomalous phenomena, or “UAP.”

Despite the questions that remain, this initiative under the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE) has been nothing short of historic. For more than 75 years, Americans pleading for the truth on the issue have been routinely ridiculed and even misled by their own government. It’s difficult to imagine the nation’s posture being anything other than one of obfuscation, secrecy, and resistance to transparency.

Documents, particularly those detailing reports from senior intelligence officials encountering “orbs”, are a stark departure from the U.S. government’s nearly century-long position of secrecy.

Lawmakers, however, have been left with more questions than answers. Who or what flies with such impunity over our sensitive military installations? Who owns this technology? Are they a threat to national security?

Across the Pacific, members of Japan’s National Diet are confronting the same questions. The May 2026 file releases from the U.S. DOW disclosed two unresolved UAP incidents from the U.S. Indo-Pacific Command. Japanese legislators only learned the details of these cases near their own territory after the American file release—not through any internal channels.

Democratic allies, it seems, face a shared challenge. For too long, elected officials in our respective nations have been denied adequate information about the phenomena operating in our common security environment. And in the U.S., whenever we are informed, it’s only through the preferred methods and timing of unelected bureaucrats deeply entrenched in our national security apparatus. In Japan, by contrast, the Ministry of Defense has stated that information may be made public when something arises that it determines should be explained.

But this raises a fundamental question: should the government alone decide what should be explained to the public?

If a grave national security threat truly exists, then elected representatives have been left with little choice but to entrust the security of their nations to the very institutions that have obscured the truth from us and even each other.

It is therefore incumbent upon us—Representatives solely accountable to the citizens of our respective nations—to work together and to seek the truth wherever we may find it; both for the good of our people and to defend against whatever threats we face from strategic competitors.

As mentioned above, among the files released by the U.S. DOW were highly significant firsthand reports from high-ranking officials in the Office of the Director of National Intelligence. The documents detail a search operation at a classified missile testing site in the Western United States, explicitly for aerial phenomena:

En route, ground teams reported spotting a UAP on FLIR [Forward Looking Infrared], describing it as “super-hot,” low to the ground, and moving east then south at high speed. The object then split into two and changed direction. Upon arrival, we scanned the area using NVG [Night Vision Goggles], FLIR, and the naked eye. The ground team suddenly radioed that the object had risen from the ground, approached within ten feet of the helicopter, dropped below us, and then sped away.

The documents were accompanied by what the DOW labeled as “related photos.”

Accounts such as these are hardly “proof” of anything, but for elected officials, they do cement the reality of our national security concerns. Missing from this account—or any account we have been allowed to access—is an answer to a fundamental question: What do the various U.S. government agencies believe these objects are? Are they merely civilian drones? Do they represent technology belonging to a foreign actor? And if someone within the government does know, who decides that elected officials shouldn’t?

Members of Japan’s UAP Parliamentary League, led by former Japanese Defense Minister Yasukazu Hamada, share similar concerns.

DOW data, released through the Pentagon’s All-domain Anomaly Resolution Office (AARO) in August of 2023, identified specific regions of Japan, particularly in the western and southern parts of the country, as being among the world’s notable hotspots for UAP reports.

One such instance occurred as recently as July of last year. Security guards at the Genkai Nuclear Power Station in Saga Prefecture observed three luminous objects in the sky above the facility. The lights remained visible for nearly two hours; long enough for local police to arrive and observe them. The police stated that what they themselves observed was an airplane, leaving a discrepancy between the two accounts. The incident was also recorded by Kyushu Electric Power’s security cameras, but the footage has not been made available even to members of the National Diet. Police have likewise declined to disclose related information on the grounds that the matter remains under investigation. As a result, elected lawmakers still lack access to the information necessary to independently assess the incident, and to this day, members of Japan’s National Diet have no answers.

Like their American counterparts, Japanese lawmakers have been left without the tools or information for proper oversight despite reports of UAP operating near critical infrastructure within restricted airspace.

It is no longer acceptable for elected representatives to be agnostic on this issue. Events such as these, along with countless videos now made publicly available, are more than mere optical illusions and cannot be dismissed on account of prosaic explanations like parallax effect. For many members of Congress and members of Japan’s UAP Parliamentary League, the evidence presented before us indicates an unknown technology.

Our understanding of what is technologically feasible in propulsion, the manipulation of physical matter, and even space-time itself is being challenged. From what we know, our current defense capabilities appear insufficient. Furthermore, the origin of these phenomena remains unknown—not only to the U.S. and Japan, but seemingly to other nations as well. China, for instance, recently established its own military body dedicated to investigating UAP, even supplementing human resources with artificial intelligence dedicated to tracking what the People’s Liberation Army refers to as “Unidentified Air Conditions.”

We are, by all indications, in a global arms race for technological supremacy, one that is rapidly rendering today’s weapons obsolete through advances in quantum technology, artificial intelligence, and drone warfare. UAP and whatever technology allows them to operate with apparent impunity over sensitive military and nuclear installations could redefine the competition.

If harnessed by democratic allies, breakthroughs could bolster deterrence and stability in the South China Sea. Conversely, failure to establish a coordinated effort among democratic allies could give China an unforeseen technological advantage over a future invasion of Taiwan, making an already difficult fight impossible.

U.S. global leadership, along with the territorial integrity of the Pacific are at stake. For members of Japan’s National Diet, UAP investigations are of great national importance—an issue that demands cross-party attention.

As for their American counterparts, it’s clear representatives can’t reach the truth through traditional pathways that amount to asking the Central Intelligence Agency ‘nicely.’ It stands to reason that close alliances with democratic allies like Japan may be the most viable pathway for disclosure.

Indeed, if our tools are limited in scope, perhaps new revelations made by democratic allies provide a unique leverage point. After all, it was the Trump administration’s disclosure under the PURSUE program that significantly increased pressure on Japan’s Defense Ministry to acknowledge its own previously undisclosed UAP-related activities.

This is why we, as elected representatives of our nations, have engaged the Emerging Technologies Interparliamentary Caucus (ETIC) as a platform for international dialogue regarding emerging technologies and the security threats presented by UAP. Comprised of representatives from across the globe, the ETIC presents a rare opportunity to ensure elected representatives are equipped to assess potential threats, safeguard our nations, and prepare for the realities of emerging technologies in the 21st century.

Whether the phenomena we are encountering originate from an adversary or something else entirely, democratic nations cannot afford to be complacent.

The people of our nations deserve answers, and we intend to find them.

O WhatsApp está avaliando (na versão beta 26.37.10.15) a implementação do suporte ao acesso de até três contas simultâneas no mesmo dispositivo.

A opção de adicionar uma terceira conta é bem semelhante ao que já foi implementado pela Meta ao adicionar o suporte a uma segunda conta no mensageiro, exibindo a foto de perfil e o número de telefone para facilitar a identificação na hora de alternar entre os perfis.

Sincronização do papel de parede

Outro recurso que a Meta avalia implementar (na versão beta 26.37.10.16) é a possibilidade de sincronizar para todos os participantes da conversa determinadas informações, como o papel de parede (ou os temas oferecidos pelo próprio WhatsApp) importado a partir da biblioteca de fotos do aparelho, além da cor dos balões de conversa.

A definição dessa configuração para todos os participantes da conversa permite que todos os usuários visualizem as interações de um jeito semelhante, tanto para conversas individuais do WhatsApp quanto para conversas em grupo (os usuários são alertados caso qualquer alteração nesse sentido seja feita).

A sincronização desses elementos também conta com a criptografia de ponta a ponta oferecida em outros recursos do aplicativo.

No momento, ambos os recursos estão sendo testados pelo WhatsApp e estão indisponíveis inclusive para quem utiliza a versão beta do app via TestFlight.
