A worker at a US government lab got bitten by a monkey carrying a deadly virus, and it turned out nobody knew what to do about it. Around the same time, someone from the same lab tried to smuggle outbreak samples into the country. All of this while everyone's worried about AI making bioweapons. Let's take a look.

O tvOS 27 chegará neste ano com uma leva de novidades para a Apple TV 4K que, embora discretas se comparadas às de outros sistemas da Maçã, trazem melhorias bem-vindas ao dia a dia de quem usa o aparelho — do app Podcasts redesenhado a ajustes de performance por todo o sistema.

Preparamos um vídeo reunindo e demonstrando as principais mudanças da atualização. Confira abaixo:

Entre os destaques está o novo app Podcasts, que ganhou redesenho completo com suporte a programas em vídeo, alinhando a Apple TV às demais plataformas da empresa. O Apple Music também recebeu atenção: agora conta com suporte a áudio Hi-Res Lossless e com o recurso AutoMix, que cria transições automáticas entre as faixas.

Outras novidades incluem ajuste de tamanho de texto, verificação do status do AppleCare diretamente nos Ajustes (Settings) e atualização remota da Apple TV pelo app Casa (Home). O sistema também trará suporte a legendas geradas por IA on-device e melhorias no HomeKit Secure Video, agora com suporte à resolução 4K.

No quesito performance, a Central de Controle ficará mais responsiva, o AirPlay estará mais rápido, as animações ficarão mais suaves em todo o sistema e segundo a Apple os apps abrirão até 30% mais rápido, além de o sistema vir com diversas correções de bugs.

Vale lembrar que o tvOS 27 não é mais compatível com as Apple TVs HD e 4K de primeira geração, funcionando apenas nos modelos 4K de segunda e terceira gerações.

FaceTime Dual Capture is bringing simultaneous front-and-rear camera streaming to video calls in iOS 27, allowing compatible iPhones to show the caller and their surroundings without repeatedly switching between cameras.

The feature expands technology Apple introduced with the iPhone 17 family. Dual Capture already allows the Camera app to record through the Center Stage front camera and a rear camera at the same time. iOS 27 brings a similar capability directly into live FaceTime calls.

During a call, the front camera can continue showing the speaker while the rear camera displays whatever the iPhone is pointing toward. Someone attending a concert can share the performance and remain visible. A parent can show a child playing without disappearing from the conversation. A person asking for technical assistance can remain on screen while directing the rear camera toward the equipment causing the problem.

Dual Capture removes the awkward sequence of switching to the rear camera, showing something, and switching back to continue speaking face to face. Both perspectives remain available inside the same call.

FaceTime Dual Capture Changes Camera Switching

The normal FaceTime camera control changes from a simple front-or-rear choice on supported iPhones. When the caller activates the rear camera, iOS 27 keeps the front camera visible by default.

The main view displays the rear camera feed while a smaller window contains the front camera image. This picture-in-picture arrangement gives the other participant a continuous view of the caller’s reaction, commentary, or explanation.

To activate both cameras during a supported FaceTime call:

FaceTime > Start a video call > Tap the Flip button

Tapping the Flip button turns on the rear camera without immediately removing the front view. The other participant begins receiving both perspectives as part of the FaceTime stream.

The caller can disable the front view when it is no longer needed. This provides a conventional rear-camera presentation for situations where the surroundings should occupy the complete image.

To return to a single camera view:

FaceTime > Tap the camera view > Disable the front camera

The exact labels and placement may change before the public release of iOS 27 because the feature is still being tested in beta software. Its basic behavior is already established: the Flip control activates the rear camera while retaining the front camera feed.

Dual Capture does not create two independent FaceTime calls. Both images belong to one video stream, so the caller does not need a second account, device, or invitation.

The feature also differs from screen sharing. FaceTime screen sharing transmits applications and interface activity from the iPhone display. Dual Capture transmits live video from two physical cameras.

Which iPhones Support Dual Capture

Apple has limited FaceTime Dual Capture transmission to the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air. Each model includes Apple’s 18MP Center Stage front camera and the Dual Capture capability introduced in the Camera app.

An older iPhone that supports iOS 27 cannot originate a Dual Capture stream. It continues to use the normal option of selecting either the front camera or a rear camera during a call.

Older models can still receive and display a Dual Capture feed when they are running iOS 27. This allows an iPhone 16 or another supported device to see both views transmitted from an iPhone 17, even though it cannot send the same presentation back.

Both participants need iOS 27 for the new FaceTime layout to work as intended. The transmitting device must also be one of the supported iPhone 17-generation models.

This limitation is based on Apple’s official feature support rather than the simple presence of front and rear cameras. Earlier iPhones have camera hardware capable of operating in several multi-camera applications, but Apple has not extended its native Dual Capture implementation to them.

Third-party applications have offered forms of simultaneous multi-camera recording for years through Apple’s developer frameworks. The difference is that iOS 27 integrates the experience into FaceTime, where users can activate it through the familiar camera-switching control.

iPhone 17 Owners Receive a Second Dual Capture Feature

Describing FaceTime Dual Capture as retro-compatible with the iPhone 17 does not fully explain its relationship with the hardware. The iPhone 17 family introduced Apple’s native Dual Capture recording in 2025, and iOS 27 now gives that existing camera system another purpose.

Inside the Camera app, Dual Capture produces a saved video containing front and rear views. Apple lists support for recording at up to 4K Dolby Vision at 30 frames per second on the iPhone 17.

FaceTime uses the camera pairing for live communication instead. Network quality, bandwidth, device temperature, and FaceTime processing can affect the transmitted resolution, so users should not assume that a call will preserve the Camera app’s maximum 4K recording specification.

The Center Stage front camera also contributes more than resolution. Its square sensor gives the iPhone greater freedom to adjust framing without requiring the device to be physically rotated. Center Stage can help keep the caller positioned inside the smaller front-camera view while the rear camera follows the subject being shared.

That combination makes Dual Capture more useful than placing two untreated camera feeds beside each other. FaceTime can preserve the speaker’s presence while directing most of the screen toward the event, object, or location being discussed.

The feature may require more processing power and energy than an ordinary single-camera call. Running two camera sensors while encoding and transmitting live video can increase battery consumption and device temperature, especially during long calls over cellular data.

Apple has not published separate battery estimates for Dual Capture FaceTime calls. Users planning extended sessions may want access to power and a stable Wi-Fi connection.

iOS 27 Prepares FaceTime for iPhone 18

FaceTime Dual Capture arrives shortly before Apple’s expected iPhone 18 generation, making it likely to become part of how the company demonstrates the new phones’ camera and communication abilities.

Apple has not announced the iPhone 18 lineup or confirmed its final camera specifications. Compatibility with FaceTime Dual Capture is therefore expected from the software’s “iPhone 17 and newer” positioning, but individual iPhone 18 models should not be treated as confirmed until Apple presents them.

The software release gives existing iPhone 17 owners access without requiring another hardware purchase. That approach also provides Apple with a working FaceTime feature before the next iPhone launch rather than introducing the camera mode and communication interface at the same moment.

Future hardware could improve the experience through faster processors, stronger image stabilization, upgraded sensors, or more efficient video encoding. None of those additions is required for the supported iPhone 17 family, which already contains the camera system needed to transmit both views.

Dual Capture is only one part of the FaceTime update. Apple is also improving video-call quality when the network connection is weak, addressing a problem that becomes especially relevant when two live camera views require transmission. Traditional Chinese support is joining FaceTime Live Captions as well.

The weak-connection improvement may determine how dependable Dual Capture becomes away from Wi-Fi. A feature designed for travel, events, repairs, and outdoor calls needs to tolerate changes in cellular bandwidth without freezing both views or forcing the session to end.

FaceTime Dual Capture remains part of the iOS 27 beta as Apple prepares the public update for September. Apple can still adjust the interface, performance, device requirements, and picture-in-picture behavior before the completed software reaches iPhone 17 owners.

One answer to the Fermi Paradox is that advanced civilizations develop AI and lose interest in space travel. A researcher now argues that's backwards: AI, robots, and cheap probes make space exploration easier. Which means the paradox gets worse.

Over the years, physicists have become increasingly enamored with “quantum weirdness,” the many strange features of quantum mechanics that are extremely hard to explain. In a new paper, a group of researchers have tried to cut through the weirdness by analyzing how causal order really works. By doing so, they hope to set up a deeper framework that can combine quantum mechanics with gravity. Let’s
