RetinaDesk agora mostra o máximo de monitores suportados por cada Mac

14 August 2026 at 19:02

Há dois meses, falamos aqui sobre o RetinaDesk, um site muito bacana que ajuda você a escolher o melhor monitor externo para o seu Mac, levando em conta todas as especificidades dos computadores da Apple.

Pois bem, recentemente, a ferramenta ficou ainda mais completa com a adição de uma página que ajuda você a descobrir, de maneira extremamente intuitiva, a quantidade máxima de displays externos suportados pela sua máquina.

O banco de dados da ferramenta cobre todos os Macs com Apple Silicon lançados até hoje, bem como suas respectivas variantes — detalhe que joga o total de computadores listados pelo RetinaDesk para nada menos que 53.

Encontrar essa página é fácil: basta acessar o site do RetinaDesk, clicar na aba “Tools” na parte de cima da tela e, depois, selecionar a opção “Mac External Display Support by Chip” — ou simplesmente acessar esse link. Feito isso, é só selecionar o modelo do seu Mac na seção “Which Mac is it?” e, em seguida, sua respectiva variante — indicada pelo chip e o ano de lançamento (e, às vezes, o número de portas do computador) — em “Step 2”.

RetinaDesk Mac External Display Support by Chip
Captura de tela/RetinaDesk

Uma vez que você indicar o modelo do seu Mac, o número máximo de monitores externos ao qual ele pode ser conectado deverá aparecer à direita da tela, junto de uma ilustração do seu “setup máximo” — ou seja, com o maior número de monitores possível.

A nova página, no entanto, não para por aí, já que ela também conta com outra seção a qual ajuda você a montar setups com diferentes combinações de monitores, os quais podem ter resoluções e taxas de atualização distintas — sempre levando em conta, é claro, as limitações do seu computador. Ela também é uma boa forma de descobrir se o seu Mac suporta uma resolução ou uma taxa de atualização (ou uma combinação dessas duas coisas) específica.

RetinaDesk Mac External Display Support by Chip
Captura de tela/RetinaDesk

A seção “What each built-in port can drive”, por sua vez, exibe com quais resoluções/taxas de atualização cada porta do seu computador é compatível, além de revelar a sua versão (se é Thunderbolt 4 ou 5, por exemplo). Logo abaixo, temos a seção “How you can arrange the displays” que, como seu nome indica, mostra todas as combinações possíveis de monitores para a sua máquina.

Por fim, a ferramenta também deixa você comparar um Mac qualquer com outro modelo da sua escolha, checar se sua máquina precisa estar no modo clamshell para suportar um setup específico e aprender sobre soluções alternativas e suas respectivas concessões.

Assim como o resto das ferramentas do RetinaDesk, essa nova página é totalmente gratuita, com o único “porém” sendo o fato de que ela não está disponível em português — problema que, é claro, pode ser facilmente remediado com a ajuda das ferramentas de tradução dos navegadores atuais.

Muito útil, não? 🖥️

App substitui notificações do Lembretes para você nunca mais esquecê-las

14 August 2026 at 17:43

O aplicativo Lembretes (Reminders) da Apple certamente é bem útil para a maioria dos usuários convencionais, mas um tanto quanto limitado para quem tem problemas sérios de esquecimento ou transtornos como o TDAH 1Transtorno do Déficit de Atenção com Hiperatividade..

Isso porque ele não notifica o usuário sobre lembretes definidos com a Siri sem um horário, simplesmente esquece lembretes quando as notificações são descartadas e conta com opções um pouco duvidosas de soneca.

Criado por Marco Arment (desenvolvedor responsável pelo famoso Overcast), o Unforgetful é um app desenhado para resolver esses três problemas. Ele usa os lembretes já cadastrados no app nativo da Apple e adiciona uma camada própria de notificações para ajudar o usuário a lembrá-los sempre.

Com uma filosofia minimalista (nada de pastas), o app entrega notificações que se repetem até que a tarefa seja concluída ou excluída. A soneca, por sua vez, tem intervalos que escalam à medida que o usuário cochila mais.

Unforgetful
Unforgetful
Unforgetful

E tudo isso sem a necessidade de importar ou de cadastrar novos lembretes: basta substituir as notificações do app nativo pelas do Unforgetful para que tudo funcione de fato — inclusive com suporte à criação de lembretes por voz usando a Siri.

Além disso, o app conta com diferenciais como a captura rápida de lembretes com o Ditado, notificações espaçadas, backlogs de tarefas que não acumulam e lembretes baseados em localização com atraso configurável, para não notificar você antes da hora certa.

Disponível para iOS e macOS como um aplicativo universal, a assinatura unificada do app custa R$130/ano e quem baixá-lo tem direito a um teste gratuito de um mês.

Version Tracker permite gerenciar quase 40 fontes de apps no macOS

14 August 2026 at 15:25

Quem conta com muitos aplicativos instalados no Mac geralmente pode enfrentar dificuldades para monitorar as versões de cada um deles e até mesmo atualizá-los.

Essa dificuldade aumenta ainda mais para quem conta com muitos softwares instalados fora da Mac App Store, e mais ainda caso você seja um desenvolvedor e faça o uso de vários gerenciadores de pacote. O Version Tracker é um novo aplicativo que atua em todos esses cenários.

Version Tracker

Ao estilo do velho MacUpdater (que foi descontinuado no início deste ano), o software faz uma varredura no macOS para monitorar 39 fontes diferentes de apps — desde aqueles disponíveis na Mac App Store, passando pelos que adotaram o framework Sparkle ou por vários gerenciadores de pacotes.

Version Tracker

Desenvolvedores, por exemplo, conseguirão verificar e atualizar (individualmente ou em lote) com facilidade as versões de dependências instaladas por gerenciadores como Homebrew, pip, npm, Docker — que por padrão são fragmentadas em vários mecanismos de atualizações.

O app conta com uma versão gratuita que permite verificar 48 fontes sem limite de tempo. Para mais fontes e atualização com um clique, é preciso assiná-lo (a assinatura custa a partir de 20€) ou comprá-lo por 50€ (essa compra inclui updates para todas as versões 1.x do software).

Por que os ícones do Dock do Mac pulam?

12 August 2026 at 11:30

Para acessar os seus aplicativos prediletos do Mac com uma maior rapidez, é possível adicionar os ícones ao Dock — acessível por padrão na parte inferior da tela (mas que também pode ser colocado em uma das laterais, se você assim preferir).

Mas você já se perguntou por que esses ícones, em certos momentos, começam a pular?

Isso pode ser causado por diversos motivos, como veremos a seguir! 👨‍💻

  • O aplicativo foi aberto;
  • O app foi recentemente atualizado na Mac App Store;
  • Ele travou;
  • É necessária uma ação para que o app funcione;
  • O app terminou de carregar;
  • É necessário salvar algo no app antes de fechá-lo (como um documento do Pages, por exemplo).

Se quiser, é possível desativar facilmente esse efeito ao abrir os apps.

Para isso, abra os Ajustes do Sistema (System Settings) e clique em “Mesa e Dock”, na barra lateral.

Em seguida, desmarque a opção “Animar abertura de aplicativos”.

Can tissue chips overcome the limitations of animal testing?

11 August 2026 at 20:14

Animal testing has shaped modern drug development for decades, but its limitations become especially visible when scientists evaluate cancer immunotherapies. These treatments are designed to stimulate the immune system to recognize and destroy malignant cells, yet the same powerful immune activation can trigger life-threatening complications in patients. Researchers at the University of Rochester are developing a human-cell-based alternative: miniature tissue models known as organs-on-a-chip that could help predict these toxicities before experimental medicines reach clinical trials.

The work is being led through the university’s Translational Center for Barrier Microphysiological Systems, or TraCe-bMPS. The center is building drug-development tools around modular µSiM tissue chips, devices that contain ultrathin membranes populated with human cells. Unlike conventional laboratory cultures, these systems are engineered to reproduce key features of biological barriers, including the physical separation between tissues, controlled exposure to drugs, and measurable inflammatory responses. Their modular construction also allows the devices to be manufactured in large quantities with consistent dimensions and materials.

The platform is based primarily on acrylic components and incorporates membranes designed to mimic interfaces found in the human body. Such barriers regulate the movement of molecules and immune cells between compartments, making them central to drug absorption, toxicity, and inflammation. By assembling reproducible chips with human cells, researchers can study how a therapy affects a tissue under conditions that more closely approximate human biology than many animal models. The design also makes it possible to modify individual components for different organs or disease settings.

A major feature of the Rochester system is the integration of sensors directly into the chips. Developed in part through the work of biomedical engineering professor Benjamin Miller, these sensors can track barrier function and inflammatory signaling in real time. Instead of waiting until the end of an experiment to examine damaged cells, researchers can observe how a tissue responds as a drug is introduced. Changes in electrical or molecular signals may reveal that a barrier is becoming more permeable or that inflammatory pathways are being activated, providing an early warning of toxicity.

The immediate focus is on two severe complications associated with some cancer immunotherapies. Cytokine release syndrome, commonly called CRS, occurs when activated immune cells release large quantities of signaling proteins known as cytokines. The resulting systemic inflammation can cause fever, low blood pressure, breathing difficulties, and, in the most serious cases, organ failure. Immune effector cell-associated neurotoxicity syndrome, or ICANS, can affect the nervous system, producing confusion, seizures, impaired speech, or other neurological symptoms. Both conditions are difficult to predict reliably with animal testing because species differ in immune signaling networks and cell-surface receptors.

“The goal is to predict these toxicities from human cells on a chip, before a drug ever reaches a patient, and to do it without relying on animal models that have repeatedly failed to predict CRS in people,” says James McGrath, director of TraCe-bMPS and the William R. Kenan Jr. Professor of Biomedical Engineering. The approach does not simply attempt to reproduce a whole human body in miniature. Instead, it focuses on specific biological barriers and immune interactions that are directly relevant to the safety question being studied.

The project has now reached an important regulatory stage. The team was accepted into the US Food and Drug Administration’s Innovative Science and Technology Approaches for New Drugs, or ISTAND, pilot program. ISTAND is intended to help evaluate emerging methods that could improve drug development and eventually support regulatory decisions. Acceptance does not mean that the tissue-chip platform has already been approved for routine use, but it creates a formal pathway for the researchers to work with the FDA on defining the evidence needed for qualification.

The Rochester group is preparing a detailed qualification plan that will describe clinical considerations, timelines, data-sharing procedures, and statistical methods for evaluating the technology. If the platform ultimately receives FDA qualification, pharmaceutical companies could use its results as part of the evidence submitted in support of new drug applications. Such recognition would represent a significant step for organs-on-a-chip research, which has expanded rapidly but has only rarely progressed into formal regulatory programs.

The effort comes as US regulators seek alternatives to animal testing in preclinical safety studies. The FDA Modernization Act 2.0, enacted in 2022, opened the door for non-animal methods, while the agency’s 2025 roadmap outlined further efforts to reduce reliance on animal models. Researchers say pharmaceutical companies are showing strong interest because many immunotherapies are already in clinical development and carry risks of CRS or ICANS. The Rochester team collaborated with Graham Marsh of the Critical Path Institute and consulted with scientists at Pfizer about how the tool could fit into real-world drug development. If successful, the technology could give researchers a more human-relevant way to identify dangerous immune reactions early, helping developers eliminate unsafe candidates and refine promising treatments before patients are exposed.

New Evidence Reshapes Understanding of Cereal Domestication’s Earliest Stages

11 August 2026 at 19:51

Around 11,000 years ago, communities in southwest Asia began one of the most consequential experiments in human history: growing their own food. Wild cereals, legumes and fruit-bearing plants were gradually brought under human management, setting in motion the transition from mobile hunter-gatherer lifeways to farming societies. For decades, archaeologists have assumed that one of the earliest signs of this transformation was an increase in cereal grain size. A new study, however, suggests that some of the biggest grains found at the dawn of agriculture may not have been genetically altered at all. They may simply have grown in wetter conditions.

The findings, published in the Proceedings of the National Academy of Sciences, challenge a central assumption about how cereal domestication began. Researchers studying charred barley and emmer wheat grains from the Early Neolithic sites of el-Hemmeh and Sharara in the southern Levant found that the plants still possessed fully wild characteristics during the earliest phases of the Pre-Pottery Neolithic. Their ears had brittle rachises, the structures that naturally break apart when mature, allowing seeds to disperse in the wild. There was no evidence of the tough, non-shattering rachis that later became one of the defining features of domesticated cereals.

The absence of non-shattering forms is significant because a tough rachis makes harvesting far more efficient. In wild cereals, the rachis fractures as the plant ripens, scattering seeds before people can collect them. A mutation that keeps the grains attached would have offered major advantages to human harvesters and could then have spread through repeated cultivation and replanting. Researchers have therefore often treated the appearance of non-shattering cereals as a key marker of domestication. Grain size, by contrast, has frequently been interpreted as an earlier signal that people were already selecting plants through cultivation.

At el-Hemmeh and Sharara, however, grain size told a more complicated story. Barley and emmer wheat remained morphologically wild, yet their grains varied dramatically. Some were as small as typical wild cereals, while others fell within the size range commonly associated with domesticated plants. If large grains were the product of genetic selection caused by systematic tillage, the researchers expected to find other evidence of intensive cultivation. Instead, the ecological evidence pointed toward relatively low-disturbance environments.

The team examined the weed species preserved alongside the cereal remains. Weeds are valuable archaeological indicators because different plants thrive under different environmental conditions. Species associated with heavily tilled or frequently disturbed soils were not dominant in the assemblages from these early sites. This weakened the argument that repeated ploughing or intensive soil preparation had already created strong selection for larger seeds. The researchers began looking for another explanation for the striking variation in grain size.

Their answer came from stable carbon isotope analysis. Carbon exists in several naturally occurring forms, or isotopes, and plants incorporate these isotopes in ways that are influenced by their growing conditions. In cereals, the stable carbon isotopic composition of a grain can reflect the balance between carbon uptake and water loss during photosynthesis. When plants experience water stress, changes in gas exchange through their leaves alter the carbon isotope signal recorded in their tissues. By measuring this signal in ancient grains, scientists can reconstruct aspects of the moisture conditions under which the plants grew.

The results showed a strong relationship between grain size and water availability. Barley grains that reached domestic-sized dimensions had carbon isotope values indicating that they developed under wetter conditions. Smaller, wild-sized grains carried signatures consistent with considerably drier growth environments. The difference suggests that environmental moisture, rather than inherited genetic change, was responsible for much of the early increase in cereal grain size. In other words, the same wild plant population could produce grains of very different sizes depending on the conditions it experienced during development.

This phenomenon is known as developmental plasticity: the ability of a single genotype to produce different physical traits in response to the environment. It is widespread in plants and can affect characteristics such as height, leaf area, flowering time and seed production. In the Early Holocene southern Levant, developmental plasticity may have created the visual impression that cereals were already becoming domesticated. People collecting and replanting the largest grains might eventually have generated genetic selection, but the initial size increase itself appears to have been ecological rather than evolutionary.

“Environmental conditions provided a much better explanation for the observed variation in grain size than genetic selection under tillage,” said Dr Jade Whitlam of the University of Oxford, who led the study. The researchers propose that genetic selection for larger grains may have occurred later than previously thought, perhaps after selection for non-shattering rachises had already begun. This reverses the sequence often assumed in models of domestication and places greater emphasis on the complex interaction between climate, plant biology and human harvesting practices.

The study also reframes the origins of agriculture as a gradual process of niche construction rather than a sudden decision to domesticate plants. Early communities altered their relationship with wild vegetation through harvesting, protection, transport and repeated use of particular landscapes. These practices may have changed plant populations long before crops displayed unmistakable domestication traits. By combining archaeobotany, weed ecology and stable isotope evidence, the researchers argue that the first steps toward agriculture were not necessarily driven by deliberate genetic engineering of crops, but by prolonged human management operating within a variable environment. The result is a more nuanced picture of farming’s origins—one in which climate could temporarily make wild cereals look domesticated before their genomes caught up.
