tech 3A total lunar eclipse, or "blood moon," will occur on March 3, 2026. It will be fully visible across North and Central America, partially visible in parts of Asia, but not visible from Europe or Africa.
The period of totality, when the moon turns red, will last about 12 minutes near dawn. Viewing requires no special equipment, only a clear, high vantage point as the moon will be low on the horizon.
The red color is caused by sunlight being filtered through Earth's atmosphere and projecting onto the moon's surface. Total lunar eclipses are observable from anywhere on Earth's night side and occur roughly every 2.5 years.
Main topics: The 2026 total lunar eclipse event details (date, visibility, timing, viewing tips); the scientific explanation for the red color; and the comparative frequency of lunar versus solar eclipses.

tech 6NASA has postponed the Artemis II crewed lunar flyby mission from a tentative March 6 date to a new launch window in April. The delay is due to a failure in the helium flow system within the rocket's interim cryogenic propulsion stage, which is essential for engine purging and tank pressurization.
The issue requires repair in the Vehicle Assembly Building, preventing a March launch. NASA is working to preserve the April window, pending successful repairs and schedule alignment.
The mission has faced previous setbacks, including hydrogen leaks during earlier tests, though a subsequent dress rehearsal was successful. The Artemis II mission aims to send astronauts farther than any crewed spacecraft has traveled since Apollo.
The main topics covered are the launch delay and its technical cause, the repair process and schedule, the mission's historical context and importance, and previous testing setbacks.

tech 4The persistent myth that sharks are a significant threat to undersea internet cables is largely false. While minor interactions can occur, the real story is the human effort behind maintaining this critical global infrastructure.
The article focuses on the history and retirement of the pioneering TAT-8 cable, the first transatlantic fiber-optic system, which revolutionized global communications. It highlights the dedicated work of thousands of people who build and maintain these cables, ensuring the seamless digital connectivity most take for granted.
The main topics covered are the debunking of the shark bite myth, the history and significance of the TAT-8 cable, and the human labor behind the global subsea cable network.

brasil 4Resumo objetivo: As autoridades israelenses continuam demolindo casas palestinas em Jerusalém Oriental, principalmente no bairro de Silwan, justificando-as pela falta de alvarás de construção — licenças que são sistematicamente negadas aos palestinos. Essa política, intensificada após outubro de 2023, serve a uma estratégia de planejamento urbano colonial que visa deslocar comunidades palestinas e expandir assentamentos israelenses, gerando desabrigados e precariedade forçada. Os dados mostram uma aceleração do processo, com centenas de estruturas, incluindo casas, destruídas e milhares de pessoas deslocadas.
Principais tópicos abordados: 1. Demolições de casas palestinas em Jerusalém Oriental (especialmente em Silwan) com base na falta de alvarás. 2. Sistema de planejamento urbano discriminatório que impossibilita palestinos de obter licenças de construção. 3. Estratégia política e colonial visando o deslocamento palestino e a expansão de assentamentos israelenses. 4. Aceleração e escala do processo após outubro de 2023, com dados sobre unidades de assentamento aprovadas e estruturas demolidas. 5. Impacto humanitário: desabrigados, deslocamento forçado e precariedade da vida palestina.

brasil 2Resumo objetivo:
O artigo discute um debate dentro da esquerda europeia sobre a estratégia política a ser adotada. De um lado, há quem defenda um "populismo patriótico", que priorize a linguagem nacional e abandone pautas identitárias para reconquistar as classes populares, usando como exemplo o declínio de partidos como o Podemos na Espanha. Do outro lado, contesta-se essa visão, argumentando que o populismo bem-sucedido — com exemplos na América Latina e na França — deve integrar lutas como antirracismo e libertação nacional, em vez de abandoná-las.Principais tópicos abordados:
1. A defesa de um "populismo patriótico" na esquerda europeia como resposta aos avanços da extrema-direita.
2. A crítica a essa visão, com base em experiências na França e na América Latina que combinam soberania popular com pautas identitárias e antirracistas.
3. A análise do caso espanhol, discutindo os supostos erros de elitismo formal (linguagem acadêmica) e de conteúdo (agendas identitárias) de partidos como Podemos.
4. A reflexão sobre a natureza do populismo, que exige equilíbrio entre identificação com o povo e uma figura de autoridade excepcional. -
tech 6The US set a record for new energy storage installations in 2025, adding 57 gigawatt hours to the grid, a nearly 30% increase from the previous year. This growth occurred despite a politically hostile environment for renewables, with battery tax credits largely spared from cuts.
The report predicts continued rapid expansion, with storage capacity expected to jump another 21% in 2026. Texas is highlighted as a major success story, where market-driven grid policies have enabled significant solar and storage growth, positioning it to become the national leader in deployed storage.
A key trend is the rise of stand-alone battery installations not tied to specific solar projects, which helps grids manage soaring demand and utilize existing infrastructure more efficiently by storing excess off-peak energy.
Main Topics: Record US energy storage growth; political resilience of batteries; Texas as a leading market; the rise of stand-alone storage; grid optimization benefits.

infosec 5A financially motivated, unsophisticated threat actor used generative AI to compromise over 600 FortiGate firewalls across more than 55 countries. The attacks succeeded by exploiting exposed management ports and weak credentials, not software vulnerabilities, with AI helping automate reconnaissance, tool creation, and data parsing. The actor specifically targeted credentials and backup infrastructure, like Veeam servers, to enable potential ransomware attacks. This incident demonstrates how AI is lowering the technical barrier, allowing less skilled individuals to achieve attack scale previously requiring larger teams.

infosec 2The Enigma cipher machine, a Nazi encryption device, is still relevant for modern cybersecurity professionals. Its history demonstrates critical failures like overconfidence, lack of testing, and human error that led to its code being broken. These lessons about operational security and the dangers of assuming invulnerability are directly applicable to defending against contemporary cyber threats. The device's enduring legacy will be highlighted in a presentation at the upcoming RSAC 2026 conference.

infosec 5The Iranian state-linked threat group MuddyWater has launched a new cyberattack campaign, dubbed Operation Olalampo, targeting organizations primarily in the Middle East and Africa. The campaign delivers new, custom malware strains, including the Char backdoor which uses a Telegram bot for command-and-control. Researchers note the malware shows signs of AI-assisted development and that the campaign aligns with current geopolitical tensions. The attacks typically begin with spear-phishing emails and have also involved exploiting server vulnerabilities.

infosec 3The article discusses the growing need for AI systems to provide verifiable proof of their specific decisions, not just overall performance metrics. It highlights that dashboards and monitoring tools are insufficient for accountability when incidents occur, as investigators require a factual record of each action. The main topics covered are the accountability gap in AI runtime decisions, the limitations of explainability and telemetry, and the emerging concept of "proof of decision" to create tamper-resistant records of AI actions.
