Os corajosos que instalaram as versões beta do iOS 27, do iPadOS 27 e do macOS Golden Gate 27 certamente devem ter notado um aviso no topo do aplicativo Ajustes (Settings) sobre uma indexação do Spotlight em andamento.
Isso ocorre porque o Spotlight indexa o conteúdo do seu dispositivo para que seja possível pesquisar tudo o que está nele.
No caso de uma atualização de software (como as betas), o índice do Spotlight é atualizado quando você instala novos aplicativos ou recebe novos emails e mensagens de texto, por exemplo.
Usando truques simples — nem sempre bem-vindos, é verdade —, é possível acelerar o processo de indexação (que pode levar horas ou dias, dependendo da quantidade de conteúdos). Veja como! 😉
Deixe o seu dispositivo sem uso, ou seja, de forma que você fique um tempo sem mexê-lo;
Conecte o iPhone, iPad ou Mac à energia;
Conecte o aparelho à internet usando uma rede Wi-Fi ou Ethernet, caso os emails ou outros dados precisem ser baixados para a indexação.
A Apple afirma que é possível que sejam vistos, durante esse processo de indexação, alertas como:
Um indicador de progresso na parte superior da janela do Spotlight ou da Siri no Mac, que é aberto quando você pressiona a combinação ⌘ commandbarra de espaço;
Uma notificação abaixo do seu nome nos Ajustes do iPhone ou iPad;
Um alerta do Mail de que a indexação está incompleta.

En 1959, en plena Guerra Fría, doce naciones se sentaron a negociar el futuro de un continente en el extremo sur del planeta y casi completamente cubierto de hielo. El resultado fue el Tratado Antártico, un acuerdo internacional que estableció que la Antártida debía ser un continente dedicado a la paz y la ciencia.
Aquel tratado creó un sistema de gobernanza único para un lugar único. Décadas después, para reforzar su protección ambiental, se firmó en Madrid el llamado Protocolo al Tratado Antártico sobre Protección del Medio Ambiente o Protocolo de Madrid. En él se declaró la Antártida como una reserva natural dedicada a la paz y la ciencia, prohibiendo la explotación de recursos minerales, salvo con fines científicos.
En la actualidad, el tratado cuenta con 58 miembros y su conservación depende de la cooperación internacional y la capacidad de alcanzar acuerdos entre países. Durante más de 60 años, este sistema ha mantenido el continente helado como un espacio excepcional de cooperación científica internacional.
Hoy en día, la Antártida está más vigilada que nunca. Satélites, bases científicas, barcos oceanográficos, sensores remotos y campañas internacionales producen cada año una enorme cantidad de datos sobre el hielo, el océano, el clima y sus ecosistemas. Sabemos más que nunca sobre su fauna, el retroceso del hielo y la contaminación.
Sin embargo, más ciencia no significa necesariamente mejores decisiones.
En un estudio publicado recientemente en People and Nature, planteamos precisamente esta paradoja: la investigación actual en el continente helado produce una gran cantidad de información, pero no siempre genera el conocimiento necesario para guiar su protección.
Para reducir ese riesgo, desde 2009 la medida CM 51-07 distribuía espacialmente el límite precautorio de captura de kril entre varias subáreas de pesca. Por ejemplo, el límite total para el Área 48 era de 620 000 toneladas por temporada, pero la subárea 48.1, que abarca gran parte de la península antártica, tenía un cupo específico de 155 000. Ese reparto buscaba evitar que la presión pesquera se concentrara excesivamente en esta región a la vez frágil, productiva y codiciada por la actividad pesquera.
En 2024, la Comisión para la Conservación de los Recursos Vivos Marinos Antárticos, el organismo internacional que regula la pesca en el océano Austral, se reunió para decidir si mantenía ese reparto espacial del cupo de kril. La medida expiró y no se renovó.
En consecuencia, desde la temporada de pesca de 2025, ya no está distribuido el límite de captura de kril entre esas subáreas de pesca. Su expiración se debió a la dificultad de alcanzar un acuerdo entre los países miembros del tratado con la información científica disponible. Este caso mostró hasta qué punto la gestión de la Antártida depende de contar con una base científica sólida, compartida y útil para apoyar decisiones colectivas.
Hoy, esto importa especialmente porque hay una fecha en el horizonte: 2048. El Protocolo de Madrid, que prohibió la explotación de recursos minerales salvo con fines científicos, podría ser revisado a partir de ese año. Se espera que en el futuro el continente sea físicamente más accesible que cuando se diseñó su actual marco de protección. Las proyecciones indican que las zonas libres de hielo podrían aumentar alrededor de un 25 % hacia finales de siglo, aumentando su accesibilidad y modificando los intereses geopolíticos y económicos sobre el territorio.
Si llegamos a posibles debates sobre recursos minerales, presencia humana o nuevas formas de explotación sin una ciencia integrada, sostenida y aceptada como base común, la protección de la Antártida podría depender más de negociaciones políticas que de una evaluación sólida de los riesgos.
La opacidad epistémica antártica
En nuestro trabajo usamos el concepto de «opacidad epistémica» para describir una situación aparentemente paradójica: puede haber muchos datos científicos y, aun así, faltar una visión clara, integrada y útil para tomar decisiones.
La opacidad surge cuando la información existe, pero está fragmentada. Cuando los estudios no son comparables entre regiones. Cuando los datos científicos disponibles no responden directamente a las preguntas que deben resolver quienes toman decisiones. O cuando la información científica existe, pero no llega de forma integrada, comprensible y útil a los espacios donde esas decisiones se toman.
En la Antártida, este problema no se debe a la falta de buena ciencia. La investigación antártica ha producido descubrimientos fundamentales para entender el planeta. El problema está en cómo se organiza, financia, coordina y utiliza esa ciencia. Un estudio reciente sobre seguimiento a largo plazo en la Antártida mostró, por ejemplo, que más del 60 % de las investigaciones se centran en megafauna carismática, como pingüinos y mamíferos marinos.
La solución no es simplemente producir más artículos científicos. Es generar conocimiento más integrado, mantenido en el tiempo y conectado con las necesidades de conservación y gobernanza. Esto implica reforzar los seguimientos a largo plazo, armonizar protocolos, coordinar observatorios, compartir datos y asegurar que las regiones y procesos menos visibles también formen parte de la agenda científica.
Afortunadamente, la comunidad científica antártica no es ajena a este problema. En los últimos años han surgido iniciativas internacionales que avanzan en esa dirección: mayor coordinación entre programas, integración de datos, identificación de prioridades comunes y esfuerzos para conectar mejor la ciencia antártica con la toma de decisiones. Son pasos importantes. Pero ¿serán suficientes y llegarán a tiempo?
No podemos seguir viviendo de espaldas a este continente. Lo que pasa en el resto del planeta llega hasta allí en forma de calentamiento, contaminación, presión pesquera, turismo o enfermedades emergentes. Y lo que ocurre allí puede repercutir en el resto del mundo a través del clima, el océano, el nivel del mar y la biodiversidad.
Mirar hacia la Antártida ya no es solo una cuestión científica o geográfica. Es una forma de preguntarnos si sabremos proteger algo antes de perderlo.

Welcome to this edition of The Intelligence Brief… This week, SpaceX launched USSF-153, a classified U.S. Space Force mission carrying a mysterious payload into orbit aboard a Falcon 9 rocket, highlighting the growing intersection between commercial spaceflight and U.S. national security operations. In our analysis, we’ll be looking at 1) what we currently know about the highly secretive USSF-153 mission, 2) how details surrounding its flight path may offer clues that classified satellites potentially based on SpaceX’s Starshield platform were aboard, 3) how the mission comes amid growing concerns about an emerging era of military competition and potential conflict in Earth’s orbit, and 4) why the launch represents another milestone for SpaceX as reusable commercial rockets play an increasingly important role in national security space missions.

A Classified Mission is Carried to Orbit
Earlier today, SpaceX launched a classified mission for the U.S. Space Force, which carried a mysterious payload to orbit on one of the company’s Falcon 9 rockets.
The mission, officially known as USSF-153, lifted off from Vandenberg Space Force Base in California at around 11:37 a.m. EDT on Thursday. Beyond that, little else is known about what, exactly, the classified payload carried aboard the Falcon 9 might have been.
Here’s a look at what we currently know about this morning’s secretive launch, and how it may be related to other recent developments involving the growing use of Earth’s orbit in the advancement of U.S. national security objectives.
USSF-153 Mission
According to the company’s website, SpaceX says the USSF-153 mission marks the 27th flight for the first stage SpaceX rocket booster supporting this mission.
The same booster was previously used for the launches of missions that included the Crew-7, CRS-29, PACE, Transporter-10, EarthCARE, NROL-186, Transporter-13, TRACERS, NROL-48, COSMO-SkyMED Second Generation FM3, and 16 Starlink missions, according to an update on the USSF-153 mission page.
“Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean,” the SpaceX update read, noting that it may be possible for sonic booms to be heard in the region around Santa Barbara and surrounding communities, adding that “what residents experience will depend on weather and other conditions.”
Clues About a Classified Payload
The launch was live-streamed by SpaceX, and the moment of takeoff of the classified mission was subsequently added to the company’s official X account. However, few additional details about the exact nature of the mission were revealed, although experts have noted that at least a few details about the rocket’s mission could be discernible from its planned flight path, offering some clues about what USSF-153 might be carrying.
Some outlets have noted the similarity between the current mission’s rocket-stage drop zones and those from past SpaceX Starlink Group 15 missions, which could mean that a group of classified satellites, possibly built using SpaceX’s Starshield satellite platform, may be part of what’s on board.
Serving as the national-security counterpart to the technologies driving SpaceX’s massive Starlink broadband constellation, the program reportedly uses the company’s existing satellite and launch technology to support national security missions. If this is indeed a part of USSF-153’s mission, it would add to the increasingly important role commercial space technologies are playing in U.S. military and intelligence operations.
A New Cold War in Space
Last week’s Intelligence Brief newsletter covered recent concerns about potential future conflict in space, which include the use of sophisticated military capabilities in space by the U.S. and foreign adversary nations.
Experts warn that Earth’s orbit might become a critical battlefield in future conflicts, with recent examples of technologies currently being tested for this that include China’s secretive Shenlong spaceplane, as well as the U.S. and its allies demonstrating similar “dogfighting,” rendezvous, and other potentially military operations in orbit.
Additionally, Russia’s longstanding pursuit of anti-satellite weapons adds to the emerging threats that may soon occupy Earth’s orbit. Although it remains unknown whether Thursday’s mission could be related to such capabilities and other technologies aimed at leveraging Earth’s orbit for military purposes, its classified nature does leave this possibility open.
A New Milestone for SpaceX
Finally, Thursday’s mission also represents a milestone in SpaceX’s busy 2026 launch schedule, with USSF-153 expected to become the company’s 104th Falcon 9 mission of the year.
Eighty of those launches have been dedicated to expanding the company’s ever-growing Starlink constellation, which now consists of more than 11,000 active satellites in low Earth orbit.
Despite the unusual secrecy surrounding its cargo, the USSF-153 launch showcases the new reusable commercial rocket industry SpaceX has developed, which is now frequently relied on by the U.S. military for carrying national-security hardware into orbit.

God told them to sell crypto. Their investors lost everything.
When Eli Regalado first heard God speak to him, he wondered whether he was hallucinating. According to Eli and his wife, Kaitlyn, He told them to get married, buy a house, and start having kids. Then in 2021, divine guidance steered them in an unexpected new direction: crypto.
That October, the Regalados later testified in court, they received holdings in a little-known digital coin. “Take this to my people for a wealth transfer,” Eli heard God say. Over time, they came to believe that He wanted them to launch their own coin.
The Regalados created INDXcoin, which they promoted through family, friends, and contacts in evangelical Christian circles. In all, more than 500 people handed over more than $3 million. But within a year, the project collapsed. Investors lost it all, leaving many to wonder where the funds went and whether they had fallen victim to an elaborate fraud.

This road map could help us decide whether to deploy solar geoengineering
Scientists have spent half a century exploring whether we could counteract climate change by releasing reflective particles into the stratosphere, mimicking the cooling effects of volcanic eruptions. But even after hundreds of studies, we still don’t know how well it would work or what else it might do—and there’s no systematic plan for clearing up that uncertainty.
Reflective, a research organization, has now attempted to fill that gap. The San Francisco nonprofit has published a detailed road map of the experiments, studies, and infrastructure that it says would be needed to make informed decisions about the use of solar geoengineering, MIT Technology Review can reveal.
This founder is teaching chips how to recycle (their energy)
Throughout the history of the computer chip, engineers have treated waste heat as an inevitable cost of a calculation. Hannah Earley, however, thinks it’s a design choice.
Earley, 31, is cofounder and CTO of Vaire Computing, which builds chips that recycle energy usually thrown away as heat, a strategy known as reversible computing. The approach could make data centers (and our laptops and phones) much more energy efficient.
Last year, Vaire announced a key breakthrough: a chip with a resonator that recovered more energy than it lost, even after the energy needed to power the component was taken into account.
Hannah Earley is one of the computing and robotics honorees on our 35 Innovators Under 35 list for 2026. Meet the rest of them here, or explore the full list across the biotechnology, AI, computing and robotics, and climate and energy categories.
Can the US battery market untangle from China?
—Casey Crownhart
The US energy storage market is growing at a record pace, which could shore up the grid and cut emissions. Crucially, this is all happening with the help of cheap Chinese batteries, which the Trump administration is trying to phase out.
Reducing reliance on any single source of crucial energy technology makes sense. But the tension raises a broader question for me: how much should countries take advantage of cheap, available tech, and how much should they cut themselves off from foreign sources to develop their own, even if it costs more?
