Ontem, falamos aqui sobre o rumor de que a Apple estaria prestes a lançar, nos Estados Unidos, um programa de assinatura de iPhones, iPads, Macs e Apple Watches, dando aos consumidores mais formas de acessar seus dispositivos.

Logo depois, o 9to5Mac encontrou, no código da beta do iOS 27, menções a um novo framework que serviria para gerenciar dispositivos alugados por meio de assinaturas como essa.

Chamado App Managed Features, ele permitirá, ao que tudo indica, que um aplicativo autorizado de financiamento ou de prestação de serviços — e não apenas o “Apple Upgrade”, como a solução proprietária está sendo chamada — registre um iPhone e realize verificações contínuas de status.

Caso haja algum problema com o registro (como pagamentos atrasados), o iPhone será colocado automaticamente em um estado intitulado “Restricted Mode” (“Modo Restrito”, em tradução livre), que bloqueia o acesso a uma série de apps do iOS, incluindo:

• Leitor de Acessibilidade (Accessibility Reader)
• App Store
• Saúde (Health)
• Lupa (Magnifier)
• Telefone (Phone)
• Relógio (Clock)
• Ajustes (Settings)
• Carteira (Wallet)
• Senhas (Passwords)
• A interface do “Restricted Mode” em si

Como é possível notar, alguns apps mais “críticos”, como o Mensagens (Messages) e o Casa (Home), poderão continuar disponíveis mesmo quando esse bloqueio estiver ativo. Segundo o 9to5Mac, no entanto, o provedor do aparelho será capaz de escolher quais apps ficarão (ou não) de fora dessa lista.

Embora restrinja o acesso aos apps do aparelho, o recurso não parece modificar assinaturas da App Store, o que significa que o usuário continuará sendo cobrado pelos seus apps e serviços mesmo após ter sido colocado no “Restricted Mode”.

Além disso, o código do iOS 27 não lista um número limite de pagamentos atrasados como condição para o bloqueio dos apps, o que significa que ficará a cargo dos serviços de assinatura decidir quando impor essas restrições de acordo com os seus termos e condições.

Há, no entanto, menções a um novo tipo de Bloqueio de Ativação (Activation Lock) chamado “Partner Finance Lock”, criado com o objetivo de impedir que usuários apaguem, vendam ou desmontem um aparelho alugado para revender suas peças.

Ainda segundo as informações, o App Managed Features faz parte do app Buscar (Find My), embora o provedor não tenha acesso à localização do dispositivo. Ao que tudo indica, essa integração existe apenas para garantir que o bloqueio continue de pé mesmo que o usuário apague ou redefina o aparelho.

Embora essas referências não tenham sido encontradas na versão Release Candidate (RC) do iOS 26.6, é possível que elas sejam adicionadas à versão final do sistema, já que, segundo a Bloomberg, o “Apple Upgrade” será anunciado na semana que vem.

A hidden biological clock has been discovered by genetic researchers, revealing how proteins act as a timing mechanism that controls living organisms’ growth into adulthood.

Cold Spring Harbor Laboratory (CSHL) researchers in New York revealed their findings in a recent paper published in the Proceedings of the National Academy of Sciences, identifying how a feedback circuit between the proteins MYRF-1 and LIN-42 functions as the worm genome’s master developmental clock.

Their research focused on the worm species Caenorhabditis elegans, revealing how these proteins set the timing of pulses that guide the worm through its development.

A Missing Biological Clock

“Development requires that cells change identity in the correct order while the organism continues to grow. How multicellular animals generate and synchronize this timing information across tissues has remained unclear,” the authors write.

The search for this missing biological clock was the core of the CSHL team’s research. Genetic and developmental problems are often expressed as a failure of developmental processes to initiate, which could be tied to problems with internal timing sequences that organize such behaviors. This marks the first time researchers have discovered a non-repeating biological clock.

“This is the central clock for all cells in the worm,” explained co-author Christopher Hammell. “It’s responsible for coordinating a finite series of sequential pulses of gene expression that must occur only once, and in order, for proper developmental progression. It’s like a ratchet. It turns genes on and off multiple times during development, but ultimately, it’s only going in one direction.”

Exploring the Genetic Issues

CSHL researchers paired the modern AI tool AlphaFold with more traditional genetic research techniques, such as protein sequencing, molecular experiments, and DNA sequencing, to identify MYRF-1’s role in the worm’s development.

The team found that protein signals both initiate and terminate developmental stages, keeping growth on track. MYRF-1 pulses fire first, then activate LIN-42, which determines the strength and duration of the timing pulses. This biological clock activates stage-specific regulatory RNAs and synchronizes developmental checkpoints, creating a rhythmic gene-regulation metronome that enforces the irreversible nature of growth and molting. 

In tests to confirm how this biological clock operates, researchers discovered that blocking MYRF-1 expression disrupts the worms’ development cycle.

Understanding the Rhythm of Growth

“We’ve never seen anything like this before,” Hammell says. “MYRF-1 is part of this master regulatory clock for all cells, but it’s also acting as a key maker and the master key for each stage of growth. Without the right key for each stage, development hits a wall and can’t progress.”

The researchers say that understanding how these proteins interact to create cellular clocks that guide development will help researchers better understand cell growth, progression, and differentiation.

“The MYRF-1/LIN-42 circuit runs in all cells,” Hammell says. “And every one of these independent cellular clocks appears to be in sync when you watch normal development. But are they communicating with each other? We’ve never thought deeply about that question before.”

A better understanding of these clocks could offer potential routes to cures for genetic and developmental issues by allowing medical science to jump-start processes that fail to initiate naturally.

Fundamentally, by restoring synchronization of these growth, development, and differentiation processes, scientists and medical practitioners could see better future success in alleviating certain genetic conditions.

The team’s recent paper, “A Molecular Timer Couples Organism-Wide Temporal Identity to Developmental Checkpoints,” appeared in Proceedings of the National Academy of Sciences on May 6, 2026.

Numerous UFO sightings, particularly near nuclear sites, raise questions about their purpose. Some suggest these crafts harvest energy from power stations, connecting spiritual dimensions with our physical realm. Historical data supports a correlation between UFOs and nuclear facilities, leading to speculation about their energy needs and where they come from.

The exploration of time measurement emphasizes the Earth's rotation as a historical clock, defining the 24-hour day. The development of mechanical clocks, notably John Harrison's marine chronometers, advanced navigation. Time's definition evolved from an Earth-centric model to atomic standards, although fundamental concepts of time remain abstract and intrinsic to the universe's creation.
