US accelerates development of next-gen chemical protection suits for fighters with new program

A Chicago-based company has been awarded an initial $23.67 million acquisition contract under the U.S. Department of War’s Accelerate the Procurement and Fielding of Innovative Technologies (APFIT).

With this Numat Technologies will accelerate the deployment of next-generation chemical and biological protection suits for U.S. Special Operations Forces.

The award is being executed in partnership with the Defense Threat Reduction Agency (DTRA) and is intended to speed the transition of the company’s technology from development into operational use.

Numat will deliver field-ready protective suits at scale

The APFIT program was established to bridge the gap between promising defense technologies and field deployment by providing procurement funding for mature innovations that are ready for operational use. Since its launch, the program has supported the rapid acquisition of advanced capabilities for the U.S. military, with total awards now exceeding $2 billion, according to a press release.

“Over the past 10 years, Numat built the MOF industrial base for this moment, where we can activate an entire supply chain, from material design through high-volume system manufacturing, to protect the Warfighter,” said Ben Hernandez, CEO of Numat Technologies.

“This contract award reflects our long-term investment in American innovation. Numat will deliver finished, field-ready protective suits at scale, made completely in the United States.”

Numat’s protection suits incorporate metal-organic frameworks

Numat’s protection suits incorporate metal-organic frameworks (MOFs)—highly porous engineered materials designed to capture and neutralize hazardous chemical and biological agents. Unlike conventional protective garments that primarily act as barriers, the company’s MOF-enabled suits are engineered to self-detoxify by neutralizing harmful substances upon contact, while also improving breathability and wearer mobility.

Under the APFIT contract, Numat will supply the MOF-enabled chemical and biological (CB) suits directly to U.S. Special Operations Forces, whose personnel often operate in environments where exposure to chemical and biological threats is a significant concern. According to the company, the suits are designed to offer enhanced protection without compromising comfort or operational effectiveness.

The contract also represents a milestone for the domestic manufacturing of metal-organic frameworks, a technology that has gained increasing attention for applications ranging from defense and industrial filtration to energy storage and environmental protection. Numat said it has spent more than a decade building a U.S.-based supply chain capable of designing, producing and integrating MOFs into mission-critical systems.

Company Chief Executive Officer Ben Hernandez said the award reflects years of investment in establishing a domestic industrial base for MOF technology and positions the company to deliver field-ready protective equipment manufactured entirely in the United States.

The latest award builds on Numat’s long-standing collaboration with several U.S. defense organizations, including the Defense Threat Reduction Agency, the Office of the Assistant Secretary of War for Industrial Base Policy, the Capability Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense, U.S. Special Operations Command, the U.S. Army and the U.S. Navy. These partnerships have helped advance MOF technology from laboratory research to scalable manufacturing, according to the company.

Beyond military applications, Numat said its MOF platform has potential uses across industrial, semiconductor and energy sectors, where advanced materials are increasingly being deployed for gas storage, chemical separation and hazardous material filtration.

The APFIT award underscores the U.S. government’s broader efforts to accelerate the procurement of innovative defense technologies while strengthening the domestic industrial base and reducing the time required to transition emerging capabilities into operational service.

5 mudanças feitas no “Battinson” em Batman: Parte 2

18 July 2026 at 23:01

Apesar do adiamento de Batman: Parte 2, o diretor Matt Reeves decidiu presentear os fãs com uma prévia inédita do novo uniforme do homem-morcego.

O traje de Bruce Wayne, interpretado por Robert Pattinson, teve mudanças que podem ditar o tom da narrativa e mostrar o que ele passou entre a vitória sobre o Charada e o futuro arco.

Como isso ajudará o super-herói contra vilões como o Victor Zsasz, Hera Venenosa e até o Pinguim ainda continua como um mistério, mas é fato que adaptações foram realizadas.

Para fins comparativos, isso também foi visto em outras obras — como a trilogia de Christopher Nolan de “O Cavaleiro das Trevas” e até no DCEU, entre Batman vs. Superman: A Origem da Justiça (2016) e Liga da Justiça (2017).

Veja o teaser e as 5 mudanças feitas no Homem-Morcego em Batman: Parte 2:

5. Protetor de queixo

No novo filme, Bruce Wayne usará uma camada a mais de proteção em seu queixo. O item do seu uniforme parece vir direto da parte da roupa em que seu pescoço é protegido e fecha toda a parte do maxilar do super-herói.

Antes, o Batman não utilizava o item — porém, todo cuidado com ganchos dos bandidos é pouco, não é mesmo? Vale notar que o equipamento é inédito nos cinemas, já que nenhuma outra interpretação do personagem o utilizou além dos extensores do próprio uniforme.

Batman-protetor-de-queixo-Img1

4. Adaptação do clássico símbolo

Com o logo da produção, é possível ver como será o símbolo que o “Battinson” usará nos cinemas agora. Foram adicionadas orelhas no morcego, mas assim como a versão anterior, ele não tem uma “cabeça” posicionada como os tradicionais.

Além disso, é notável que as bordas são mais arredondadas, o que remove parte do visual visceral que o anterior carregava. Não é revelado o porquê da mudança, mas é possível até que vejamos a alternância durante Batman: Parte 2.

Batman-Simbolos-Img3

3. Colarinho mais largo

Seu colarinho também está mais extenso, com a cobertura de toda a sua nuca agora. Este pode ser um visual mais protetivo, no entanto se assemelha bastante ao estilo que vemos dos vampiros clássicos da literatura — não de Crepúsculo, por mais que haja envolvimento de Robert Pattinson.

Possivelmente sua capa também terá alterações, que podem trazer um estilo mais sombrio e até mesmo “mitológico” para o personagem da DC Comics. Com o fim da ameaça de Charada e a partida da Mulher-Gato, talvez ele tenha precisado recorrer a aspectos “edgy” para adicionar um drama (parei com os trocadilhos) maior.  

Batman-Colarinho

2. A “Batarmadura”

No longa-metragem de 2022, já vemos o protetor de Gotham com um traje tático. Contudo, a alteração no capacete e colarinho também indicam que ele está mais preocupado com os danos físicos que sofre — o que pode levá-lo a adotar uma verdadeira armadura para suas patrulhas.

Não que ele precise usar algo ao estilo medieval, mas os indicativos apontam que veremos ainda mais mudanças no peitoral, luvas e até em suas botas para aguentar os solavancos que a tenebrosa cidade apresenta. 

Batman-Batarmadura

1. “Antenas” maiores

Por fim, mas não menos importante, Battinson agora usa antenas maiores em seu capacete. Não são tão grandes quanto as da armadura de Michael Keaton, mas com certeza diferentes dos vistos nas produções mais recentes do super-herói.

Elas podem esconder funções, como a versão de Christopher Nolan — quem sabe para esconder um transmissor para se comunicar com Alfred ou ouvir as chamadas policiais? Ou, talvez, sirva para o Batman ser mais reconhecível no momento em que estiver para enfrentar os criminosos. 

Batman-antenas-maiores

Mudanças expressivas no Batman

Com um teaser é possível reconhecer poucos elementos, mas novos trailers e imagens poderão esclarecer melhor como o uniforme de Bruce Wayne desempenhará um papel importante em Batman: Parte 2. 

Ademais, super-heróis sempre mudam de vestimenta e o homem-morcego não pode ser diferente. Não é à toa que o medo de muita gente era que Robert Pattinson fosse marcado ao longo dos anos pelos trajes mais esquisitos do Batman. Não foi o caso, mesmo com as 5 mudanças na armadura do Battinson:

  1. “Antenas” maiores

  2. A “Batarmadura”

  3. Colarinho mais largo

  4. Adaptação do clássico símbolo

  5. Protetor de queixo

PS Plus Extra ou Deluxe: qual plano vale mais a pena em 2026?

18 July 2026 at 22:09

Assinar um serviço em 2026 pesou no bolso do jogador. Os planos da PlayStation se apresentam de formas distintas, o que pode confundir muitos jogadores e gerar dúvidas sobre qual deles vale mais a pena.

A PS Plus aumentou de preço recentemente e gerou diversas questões para os jogadores, afinal de contas, qual categoria vai oferecer aquilo que você busca pelo valor mais acessível? A decisão se tornou complexa e cheia de nuances.

Contudo, é possível alinhar as ideias e entender qual plano da PS Plus faz mais sentido para você. Na prática, saberá com exatidão para onde correr e o que terá em retorno no seu PlayStation 5.

Veja o comparativo entre a PS Plus Extra e Deluxe para entender qual plano vale mais a pena assinar em 2026:

O peso da PS Plus no bolso

Antes de discutirmos recursos, entrega e mais detalhes, primeiro é preciso falar sobre os preços praticados na PlayStation Plus. Veja abaixo o comparativo completo do que é cobrado em cada categoria:

  PS Plus Extra PS Plus Deluxe Diferença de valor
1 mês R$ 74,90 R$ 86,90 R$ 12
3 meses

R$ 209,90

R$ 249,90 R$ 40
1 ano R$ 592,90 R$ 691,90 R$ 99

Como pode notar, a diferença financeira entre eles varia entre R$ 12 a R$ 99 — a depender de quanto tempo pretende se manter como assinante. Além disso, em ambos você tem os benefícios do Essential: o multiplayer online e a oferta de 3 games mensais.

O que a Sony oferece?

Para cada assinatura, o público contará com diferentes tipos de brindes para aprimorar a sua experiência. De forma óbvia, o mais caro vai acumular tudo que os demais oferecem com recursos adicionais, mas será que o custo-benefício é de se jogar fora?

A PS Plus Extra é uma categoria intermediária no PlayStation 5, que garante aos usuários acesso aos jogos mensais, modo multijogadores, coleção PlayStation Plus, Share Play e descontos exclusivos.

Porém, o verdadeiro diferencial é a presença do catálogo de títulos — que permite baixar no seu console e jogar, enquanto ele estiver disponível na plataforma, assim como o XBOX Game Pass. Quem assina o plano também pode usar o Ubisoft+ Classics, com um catálogo seleto da produtora.

Em outras palavras, quem assina a PS Plus Extra pode jogar sucessos como Final Fantasy XVI, Marvel’s Spider-Man 2, Cyberpunk 2077, God of War Ragnarök, Silent Hill 2 e até franquias como Assassin’s Creed e Far Cry. 

Final-Fantasy-XVI-Img1

No entanto, é importante ter consciência de que, ao contrário do serviço da Microsoft, a Sony não oferece lançamentos “Day One”. Dito isso, não terá Saros, Ghost of Yötei, Assassin’s Creed Black Flag Resynced e outros games que chegaram em 2026.

No máximo, haverá experiências independentes ou de outras produtoras com essa proposta — como foi o caso de Blue Prince, Big Walk, Foamstars e até Runescape: Dragonwilds. Se estava de olho em Marvel’s Wolverine ou algo do tipo, é melhor não se empolgar tanto.

Por até R$ 99 de diferença, o que o PS Plus Deluxe traz a mais? Na verdade, além de tudo o que já foi descrito até aqui (que é acumulado), ele tem outras duas propostas aos jogadores: o catálogo de clássicos e a experimentação de jogos.

Assim como o Nintendo Switch Online na concorrência, esta categoria permite revisitar o passado do PlayStation com diversas aventuras de PS1 e PS2 disponíveis para você baixar e relembrar dos “bons e velhos tempos”.

Dino-Crisis-Img1

Porém, saiba que não se pode mergulhar nesta ideia de cabeça: ainda que existam exclusivos, não verá todos os God of War, Devil May Cry e outras séries emblemáticas daquela época. É uma plataforma mais “tímida” neste sentido.

Há franquias como Armored Core, Resident Evil e Ape Escape, assim como jogos que vão de Beyond: Two Souls, Dino Crisis a até God of War III Remastered e Gravity Rush Remastered. Está muito longe de ser ruim, mas também não está próxima do ideal.

Enquanto isso, a “experimentação de jogos” é uma gourmetização das demos. Ao invés de disponibilizar demonstrações gratuitamente na loja digital, para todos, eles deixam o recurso restrito para o serviço com os seus principais games.

Lá você pode jogar algumas horas de grandes aventuras, como Saros, Death Stranding 2: On the Beach, Alan Wake II, Black Myth: Wukong, Stellar Blade e outros sucessos que chegaram ao PS5 nos últimos anos. Na maior parte deles, é possível transferir o progresso para a versão completa, caso decida comprá-la.

Ou seja, por quase R$ 100 adicionais, terá uma verdadeira biblioteca de títulos retrô e acesso a algumas demonstrações. Estas são as principais vantagens que a PS Plus Deluxe tem sobre o plano Extra no Brasil.

Qual plano da PS Plus vale mais a pena?

Em um juízo de valores, apenas o catálogo de clássicos já faz a versão mais cara compensar. Porém, apenas se o jogador for um fã de jogos antigos e queira revisitar as experiências marcantes que fizeram parte de sua própria história.

PlayStation-5-Img1-Pexels

Se levar em conta que cada um deles custa entre R$ 30 e R$ 60, se você jogar dois ou três por ano, a diferença já “se pagou”. Ainda assim, é importante considerar que você ainda perde recursos oferecidos em outros países no plano Premium, como o streaming de games pela nuvem. 

No entanto, se não é o seu caso, a PS Plus Extra é o que mais vale a pena para investir em 2026. Não é um dos valores que mais se encaixam no bolso do público, mas oferece quase todas as opções sem ter de gastar um pouco mais por um ou outro game retrô.

Além disso, se os títulos de PS1 e PS2 fizerem tanta diferença assim, também é possível comprar portáteis que rodam emuladores — encontrados entre R$ 200 e R$ 500, eles permitem ter toda a experiência e de forma personalizada, já que ROM você baixa e instala o que desejar.

Na prática, com um desses você jogará o que quiser e onde preferir, sem estar preso à TV ou monitor. Melhor isso do que ter de checar a PS Plus Deluxe com frequência, pedir todo dia para a Sony ouvir suas preces e esperar a adição do seu jogo antigo favorito.

Financeiramente, sai uma brincadeira um pouco mais cara. Contudo, ao parcelar no cartão de crédito e com apoio de cupons e ações promocionais, isso pode não ser um problema tão sério ao bolso a longo prazo. 

Com essa visão em mente, a PS Plus Extra é a melhor oferta da Sony para os assinantes em 2026. A Deluxe até vale a pena por dar acesso oficial a algumas das experiências presas ao passado, mas ainda assim tem muito a evoluir e acrescentar antes de realmente representar uma proposta viável. 

Outra preocupação esteve na mente dos jogadores. Afinal de contas, com o fim da mídia física no PlayStation, o que muda para você?

Chinese startup introduces next-gen optical links to connect thousands of high performing chips

18 July 2026 at 21:48

As AI models continue to grow in size and complexity, chipmakers are shifting their focus from individual processor performance to the ability to efficiently connect thousands of accelerators into a single computing system. 

These highly interconnected server architectures have become a key competitive area for AI infrastructure companies, which are racing to deliver the computing scale needed for models with trillions of parameters and the growing adoption of AI agents.

According to Ding Yunfan, vice president of AI framework architecture at Biren, improvements in the performance of a single graphics processing unit (GPU) are no longer enough to meet these demands. Instead, the industry’s biggest challenge is turning vast GPU clusters into unified, seamless computing platforms capable of operating as a single system.

Architecture designed to break GPU cluster limits

Biren believes the future of large-scale AI computing depends on replacing conventional electrical interconnects with optical technology. According to Ding, traditional copper-based connections are approaching their physical limits, effectively capping today’s server architectures at around 128 GPUs, the South China Morning Post reports.

To overcome that bottleneck, the company has developed a distributed, decoupled supernode architecture built around near-packaged optics (NPO), which positions optical fibres closer to the chips to increase bandwidth and improve data transmission. Biren said the approach could enable clusters with up to 1,024 AI accelerator cards, significantly expanding the scale of computing systems needed to support increasingly demanding AI workloads.

Ding said optical interconnects are becoming essential for overcoming the scalability limits of conventional server architectures. Shanghai-based Biren is among a growing number of Chinese companies tackling these infrastructure challenges. Rivals including MetaX, Enflame and Alibaba are also developing supernode architectures to compete with Nvidia’s NVL72 and next-generation NVL144 AI platforms.

Biren’s Shanghai-based rival MetaX has introduced its Xijing S600 AI supernode, featuring a single rack that connects 64 GPUs. The company said its design reduces signal loss by removing external cabling between compute nodes, switch nodes and interconnect systems, improving efficiency for large-scale AI workloads.

Looking beyond electrical links to build larger AI supernodes

Biren is also working on new approaches to expand the scale of its AI computing systems. The company’s orthogonal hardware architecture, co-developed with telecommunications giant ZTE, uses traditional electrical connections, while Biren is simultaneously testing a prototype near-packaged optics (NPO) interconnect system. 

The chipmaker said the optical approach could eventually support supernodes with more than 512 accelerator cards, helping address the growing demand for larger and more efficient AI infrastructure.

Despite growing interest in optical networking for AI infrastructure, Ding said the semiconductor industry is still in the early stages of developing and testing optical interconnect technologies. He noted that widespread adoption will require further advances before these systems can be deployed at scale.

Furthermore, Ding emphasized that the technology still requires real-world validation before it can be widely adopted. He projected that NPO optical systems could reach mass commercial deployment around 2028, as the industry continues refining the technology and addressing remaining engineering challenges.

US firm gets license to commercialize patented seawater uranium extraction technology

Austin-based SuperCritical Materials Corp. has secured a license from the U.S. Department of Energy (DOE) to commercialize a patented uranium and critical materials extraction technology developed by DOE laboratories.

The development is a significant step toward expanding future nuclear fuel supply through unconventional uranium resources.

Licensed technology is designed to extract uranium from seawater

Developed with support from the DOE’s Office of Nuclear Energy and led by researchers at Pacific Northwest National Laboratory (PNNL), the licensed technology is designed to extract uranium from seawater using advanced adsorbent materials. SuperCritical said the agreement grants the company rights to manufacture and deploy the technology at industrial scale in the United States, with plans to expand into allied nations in the future.

The announcement comes as the United States accelerates investment in advanced nuclear energy to meet rising electricity demand driven by artificial intelligence, data centers, advanced manufacturing and other energy-intensive industries. Industry experts have increasingly highlighted that while reactor development is advancing, expanding the upstream nuclear fuel supply chain—including uranium production, enrichment and fuel fabrication—remains a critical challenge.

According to the company, the world’s oceans contain an estimated 4.5 billion metric tons of dissolved uranium, representing a resource far larger than known terrestrial reserves. While extracting uranium from seawater has long been considered technically feasible, commercial deployment has remained limited due to economic and engineering challenges.

SuperCritical intends to commercialize DOE-developed process

SuperCritical said it intends to commercialize the DOE-developed process using advances in adsorption chemistry and materials science. In addition to uranium, the company believes the technology could also enable the recovery of other strategically important critical materials from seawater.

The company describes its long-term strategy as building infrastructure to support what it calls the “Intelligence Economy,” a period of economic growth expected to be driven by artificial intelligence, robotics, advanced computing, defense technologies and digital infrastructure. It argues that reliable nuclear energy and secure fuel supplies will be essential to sustaining this growth.

“Our objective is straightforward,” said Alexander Canon Bryan, founder and chief executive officer of SuperCritical Materials. “If the Intelligence Economy requires abundant, reliable nuclear energy, then it will also require abundant, reliable nuclear fuel.”

SuperCritical noted that its technical team includes former researchers from Pacific Northwest National Laboratory, including Dr. Gary Gill, a co-founder of the company and a scientist who has spent more than two decades researching uranium extraction from seawater.

The company said commercial deployment of the technology could contribute to strengthening domestic nuclear fuel supply chains while supporting broader U.S. efforts to improve energy security, expand critical materials production and reduce dependence on imported strategic resources.

The licensing agreement also aligns with ongoing federal initiatives aimed at strengthening America’s nuclear industrial base and increasing domestic production of critical minerals and materials.

Although seawater uranium extraction has been demonstrated in research settings, analysts note that large-scale commercialization will depend on achieving competitive production costs and successfully scaling the technology for industrial use. Industry observers view the DOE licensing agreement as an important milestone toward evaluating the commercial viability of the process.

MIT’s GIFT framework improves CAD designs by turning its failures into training data

Creating a realistic 3D model from a simple image remains surprisingly difficult for artificial intelligence. 

While AI can generate impressive pictures, producing the precise CAD code engineers use to design aircraft parts, cars, and consumer products is far more challenging. Even a small mistake can make a design unusable. 

Now, researchers from MIT, IBM, and Red Hat have developed a framework that significantly improves the ability of AI systems to turn 2D images into functional CAD programs, producing more accurate designs while reducing inference computation by about 80 percent.

This new research work tackles one of the biggest obstacles in AI-driven engineering, which is the shortage of high-quality CAD training data. Existing image-to-CAD systems need vast numbers of examples linking 2D images to working CAD programs, but creating those datasets is expensive and labor-intensive. 

Instead of relying on more human-created data, the new approach teaches AI using the mistakes it already makes. “We want to obtain data augmentation that is informed by the model itself,” lead study author and AI researcher Giorgio Giannone said.

Turning failed designs into training material

The team’s framework, called Geometric Inference Feedback Tuning (GIFT), works with vision-language models that convert a 2D image and text description into Python code that can be executed in CAD software to create a 3D object.

To understand where a model struggles, GIFT asks it to solve the same CAD problem multiple times in parallel. Some outputs are correct, some are close to the target design, and others are much further away. 

According to the researchers, these ‘near-misses’ are the most valuable because they reveal exactly what the model does not yet understand.

The system executes each generated CAD program and compares the resulting 3D geometry with the target using a standard engineering metric known as Intersection over Union (IoU), which measures how closely two 3D shapes match. 

Rather than discarding imperfect outputs, GIFT identifies those that are close to correct and uses them to generate new training examples.

Giannone explained, “If we sample the model 10 times and it generates 10 correct answers to the same problem, then there is not much for it to learn. We care about the in-between cases, where the model might only solve the problem 50 percent of the time.”

Teaching the model how to fix its own errors

GIFT improves the model through two complementary techniques. The first, called GIFT-REJECT, keeps alternative CAD programs that generate the correct geometry even if the code differs from the original reference solution. 

Traditional AI training often assumes there is only one correct CAD program for each object, even though engineers can create the same part in many different ways. By exposing the model to multiple valid solutions, GIFT broadens its understanding of how CAD designs can be constructed.

The second method, GIFT-FAIL, focuses on imperfect outputs. The system takes a nearly correct 3D model generated by the AI, converts it back into an image, and pairs that image with the correct CAD program. By doing so, it creates new examples that effectively teach the model how to recover from specific mistakes.

More importantly, this process requires no human intervention. The framework automatically identifies errors, creates new training data, and uses that information to improve the model.

The researchers also designed GIFT around a technique known as inference-time scaling. Instead of retraining an entire AI model, which can be extremely expensive, the system improves performance during generation. 

Rather than discarding the extra computation spent searching for better CAD programs, GIFT converts successful and near-successful attempts into new training examples that can later be used to improve the model through fine-tuning.

Moreover, users can decide how much computation they want to spend depending on their budget and time constraints.

Better CAD designs with a fraction of the computing power

When evaluated on the GenCAD-Code dataset, models enhanced with GIFT achieved a 12 percent improvement in geometric accuracy compared with a strong supervised-learning baseline. 

The framework also reduced the inference computation needed to achieve comparable performance by about 80%.

“With GIFT, we started with geometry because with engineering problems, if the geometry of a 3D shape is not correct, nothing else will be correct, but there are many other aspects to consider,” Giannone said. 

The system’s ability to learn from its own mistakes could help accelerate product development by making AI-generated CAD models more reliable. 

Engineers could move more quickly from sketches to testable 3D designs, reducing development costs, shortening design cycles, and exploring a wider range of ideas without creating large amounts of new training data.

The researchers say this is only the beginning. So far, GIFT focuses on generating correct geometry, but future versions will aim to teach AI how to design parts that are not only accurate in shape but also easier to manufacture and better suited for real-world performance. 

The study is published on arXiv.

US Air Force crews drop 36 practice bombs to validate F-15EX strike capability

18 July 2026 at 14:27

The US Air Force’s 142nd Wing has completed its first live bomb-dropping exercise with the F-15EX Eagle II, marking a key milestone in expanding the aircraft’s operational capabilities. In early May, pilots, maintainers, and munitions specialists traveled to Mountain Home Air Force Base in Idaho to carry out the training mission.

During the exercise, crews loaded 500-pound BDU-50 and 2,000-pound BDU-56 practice bombs onto the aircraft before releasing them over the Mountain Home bombing range. Although these training munitions closely resemble live bombs, they are filled with concrete instead of explosives, allowing crews to safely practice real-world weapons employment.

While the F-15EX has previously undergone weapons testing with the 85th Test and Evaluation Squadron at Eglin Air Force Base in Florida, this marks the first time an operational F-15EX unit has successfully loaded and dropped bombs as part of its mission readiness training.

F-15EX’s new combat role required months of pilot training

The F-15EX Eagle II is designed to do far more than its predecessor. Although it closely resembles the aging F-15C, the newer aircraft is built as a multirole fighter, capable of carrying out both air-to-air and air-to-ground missions. Unlocking that expanded capability, however, required months of preparation and specialized training across the 142nd Wing.

A key part of that effort was led by Maj. Jesse Loya, one of only three pilots in the wing with prior experience in air-to-ground operations. Together, the three completed a nine-month training program focused on the tactics and technical aspects of delivering precision-guided munitions. They then developed a training curriculum to teach the rest of the wing’s pilots the fundamentals of air-to-ground operations, laying the foundation for the unit’s first operational bomb-dropping mission.

According to Loya, the training at Mountain Home Air Force Base served as a stepping stone toward preparing pilots to safely employ air-to-ground weapons. The program focused on building the skills needed to handle ordnance while following a much shorter timeline than the traditional nine-month qualification course. 

He said the ability to complete the training so quickly reflected the experience and capabilities the pilots had developed throughout their careers, allowing the wing to accelerate the F-15EX’s transition into a multirole combat aircraft.

Weapons loaders play key role in prepping F-15EX

Preparing the F-15EX Eagle II for its first bomb-dropping mission required extensive training from weapons crews as well as pilots. Tech. Sgt. Tyler Phelps, one of the 142nd Wing’s experienced weapons loaders, traveled to Nellis Air Force Base in Nevada earlier this year to train with F-15E aircraft and earn certification to load bombs.

After returning to Oregon, Phelps and other certified Airmen trained the rest of the weapons team ahead of the Mountain Home mission. Seeing the bombs loaded onto the F-15EX marked the culmination of months of preparation and a major milestone for the 142nd Wing.

The training mission involved 10 sorties, during which crews dropped a total of 24 BDU-50 and 12 BDU-56 practice bombs. The operation was completed without any safety incidents, and all missions received satisfactory evaluations, marking a major step forward in the wing’s transition to the multirole capabilities of the F-15EX.

The next phase in the F-15EX’s air-to-ground certification process will involve loading and dropping live munitions. The crew is scheduled to conduct that mission at Nellis Air Force Base at the end of August, bringing the wing one step closer to full air-to-ground operational capability.

Astronomers Uncovered a Hidden Bubble Inside the Orion Nebula

18 July 2026 at 14:18

A key component of the Orion Nebula had escaped detection by astronomers until now, according to a new study in Astronomy & Astrophysics.

An international team led by Juan Diego Soler at the University of Vienna used two of the world’s most advanced radio telescopes to map neutral atomic hydrogen gas across the nebula’s outer shell at unprecedented resolution. The new maps provide a clearer view of the celestial feature, and reveal a previously uncatalogued second bubble—a shell with much less mass than earlier estimates—and a four-light-year filament of gas extending from the structure.

The Orion Nebula’s Miscalculated Bubble

Neutral hydrogen emits a faint radio signal at a wavelength of 21 centimeters, making it possible to trace otherwise invisible gas between the stars. Soler’s team solved this by combining data from the Karl G. Jansky Very Large Array in New Mexico and the FAST telescope in China. The VLA provided high resolution, while FAST picked up faint, widespread signals. Together, they produced the first detailed hydrogen map of the extended Orion Nebula, at the same scale as earlier ionized carbon maps.

Earlier calculations based on ionized carbon estimated that the front half of the shell was about 1,100 times the mass of our Sun. The hydrogen observations paint a different picture, suggesting the shell actually weighs in at closer to 100 solar masses. “Measuring mass is fundamental,” Soler said, “because it tells us about the efficiency of these newly formed stars shaping their environment with wind and radiation.”

A shell with only a tenth of the previously assumed mass significantly alters calculations of how efficiently newly formed stars shape their environment. The researchers note that molecular hydrogen, which is not detected in either the hydrogen or carbon data, may account for some of the missing mass.

A Second Bubble

The hydrogen maps also revealed an uneven distribution of gas, indicating a second, smaller cavity within the main shell. The team searched catalogs of known stars and young stellar objects in the region but found no candidate at the bubble’s center. The source responsible for creating the cavity may not be the type of object included in current catalogs.

Daniel Seifried at the University of Cologne, a co-author on the study, pointed to what that means for the models astronomers build to explain regions like this one. “These stunning observations serve as a reference for many modern astrophysical simulations investigating the evolution of gas and stars in the Milky Way. These are the kind of images that challenge the theoretical models and numerical simulations that we use to understand how massive stars affect their immediate surroundings.”

Previous models generally treated Orion’s shell as the product of a single expanding bubble. The discovery of a second cavity, with no obvious source at its center, instead suggests the nebula was shaped by multiple episodes of stellar feedback.

An Unexpected Filament

The new maps also uncovered a filament of hydrogen extending about four light-years from the shell’s western edge. Previous carbon-based observations saw only the base of this structure. The filament contains about 80 solar masses of hydrogen and does not appear to be associated with any known group of young stars. Its origin is unclear; it could be gas leaking through a weak spot in the shell or a leftover from the original cloud that existed before the bubble formed.

Claire Murray of the Space Telescope Science Institute, another co-author, framed the discovery within the broader push behind the observations. “This study is an exciting demonstration of the power of the latest-generation radio telescopes to uncover new pieces to the star formation puzzle.” Despite being one of the galaxy’s most extensively studied star-forming regions, the Orion Nebula continues to reveal discoveries.

This survey is the first scientific result from the NeAtHood project, which aims to map atomic hydrogen across nearby star-forming regions accessible to the VLA and FAST telescopes. Soler and his colleagues now plan to apply the same approach to additional targets. “Orion is only the beginning. Our newly developed methods show how future interferometers will reveal the hidden structure and dynamics of the interstellar medium—even in regions that astronomers already believed they understood well,” Soler explained.

If one of the sky’s best-studied star-forming regions still contains hidden structures, other nearby nebulae may prove equally surprising as the NeAtHood survey expands.

Electric aircraft advance as Vertical Aerospace plans first public eVTOL flight demonstration

18 July 2026 at 14:13

British aerospace company Vertical Aerospace is set to conduct the first public electric vertical take-off and landing (eVTOL) demonstration flights at the upcoming Farnborough International Airshow. 

The event represents another milestone in the company’s journey toward certification and the eventual launch of commercial electric aircraft services.

The demonstrations come at a key stage in the company’s development, Vertical Aerospace noted. In recent months, the company has unveiled its Valo aircraft, completed successful piloted transition flights, strengthened its financial position, expanded its global technology partnerships, progressed its hybrid-electric defense strategy, and continued advancing its certification program.

Valo eVTOL moves closer to commercial operations

Following successful demonstrations of the aircraft’s core capabilities, Vertical Aerospace is now shifting its focus toward the next stage of development, with efforts centered on certification, industrialization and preparing for commercial operations.

Alongside public piloted flight demonstrations of its full-scale prototype, the company will also showcase its full-scale commercial Valo aircraft model, offering visitors a closer look at the technology behind its next-generation electric aircraft.

According to Stuart Simpson, CEO of Vertical Aerospace, the company arrives at Farnborough with the key building blocks for its next phase already in place. He said Vertical has transformed over the past year by launching its Valo aircraft, achieving piloted transition flights, strengthening its financial position and expanding its industrial ecosystem, while continuing to prove the technology.

“Every milestone we deliver reduces risk, strengthens our competitive position and brings us closer to building one of the world’s leading electric aerospace companies,” Simpson noted. A major highlight of Vertical Aerospace’s presence at the Farnborough International Airshow will be its planned flight demonstrations, which are set to mark the first public eVTOL aircraft demonstrations at the event.

Company targets key certification and production milestones after expanding flight tests

The company intends to conduct demonstration flights throughout the show, subject to approved flight conditions. The planned flights follow the UK Civil Aviation Authority’s recent expansion of Vertical’s Permit to Fly, allowing the company to carry out public demonstrations beyond its Flight Test Centre at Cotswold Airport for the first time.

Following the expanded flight approval, Vertical’s test pilots have successfully operated the aircraft across multiple locations, including RAF Brize Norton, RAF Benson, Blackbushe Airport and Farnborough Airport. These flights have expanded the company’s test program, providing valuable experience across different operating environments.

The company is also targeting several important program milestones that will support the development, production, and commercial rollout of its aircraft. These include completing the Critical Design Review (CDR) by the end of 2026, which will establish the certifiable design baseline for the aircraft and enable the production and testing of certification-conforming models. 

Furthermore, the UK firm plans to bring its early production aircraft assembly facility online in Q3 2026 and expand the Vertical Energy Centre in Q4 2026 as part of its industrialization efforts. In addition, Vertical expects to select a long-term turbogenerator supplier during 2026, ahead of beginning hybrid-electric flight testing in the first half of 2027.

7 coisas que o Switch 2 pode fazer e o PlayStation 5 não

18 July 2026 at 14:09

O Nintendo Switch 2 apresenta uma nova geração de jogos, com tecnologias inéditas e que representam um patamar diferente para os jogadores. 

Por outro lado, o PlayStation 5 está há alguns anos no mercado e já se estabeleceu bem entre o público. Com gráficos de ponta e SSD de altíssima velocidade, ele se tornou um titã na indústria.

Algumas diferenças entre os dois videogames são notáveis, mas será que o dispositivo híbrido da Big N está "tão atrás" assim do console de mesa da Sony?

Apesar do desempenho menor em força bruta, o "pequeno gigante" da Nintendo traz facilidades únicas. Confira 7 coisas que o Switch 2 pode fazer e que dão um verdadeiro baile no PlayStation 5.

7. Virtual Game Card

Apesar de criticados no início, a presença dos Virtual Game Cards é um grande avanço no console da Nintendo. Com eles, podemos acessar jogos digitais sem a verificação de licenças ou conexão online. 

Assim como os cartuchos físicos, eles são mostrados no Switch 2 como “acesso imediato” — mesmo que esteja em uma conta que não comprou determinada experiência. Assim, se torna uma forma mais simples de acessar os títulos do que o visto no PlayStation 5.

6. Chamadas de vídeo com o GameChat

Sem a necessidade de baixar apps externos, você pode convidar diversos amigos para uma chamada de vídeo enquanto joga qualquer título no videogame da Nintendo. Ele tem suporte para encontros de até 4 pessoas, com vídeo, e 12, via áudio.

A exigência do Nintendo Switch Online é um impedimento chato, mas permite uma interação muito boa entre os usuários — mesmo que cada um jogue algo diferente. Neste aspecto, o GameChat se sobressai como recurso social.

5. Compartilhamento de jogos

Embora o PlayStation 5 consiga ser habilitado para compartilhar jogos com amigos, por manobras do sistema, no Nintendo Switch 2 isso é muito simples e permite que usuários possam aproveitar melhor os games que estão “parados”.

A funcionalidade pode ser ativada no seu Grupo de Família, basta aproximar fisicamente o seu console de outro que esteja incluído neste conjunto e enviar o Virtual Game Card para outra pessoa jogar. Mesmo que funcione por um período limitado, ele já ajuda bastante a expandir a diversão.

4. Armazenamento facilmente substituível

Já tentou abrir o PS5 para trocar o SSD? Mesmo que seja possível, exige um conjunto de habilidades que nem sempre uma pessoa está apta a executar. Na prática, aumentar o armazenamento pode ser uma tarefa desafiadora para uma parcela da comunidade.

No Nintendo Switch 2 você não pode trocar o componente interno, mas é possível adquirir cartões microSD Express que aumentam bastante a capacidade do console híbrido. Basta levantar a haste do suporte horizontal, encaixar o hardware ali e seu problema estará resolvido.

3. Jogar juntos com o GameShare

Já pensou como seria bacana aproximar dois videogames e seus usuários poderem jogar o mesmo título, mesmo que apenas um deles tenha comprado? O videogame da Big N permite isso, o que abre ainda mais o leque para curtir diversas experiências em conjunto.

O mais incrível é que existem jogos do Switch 2 que podem funcionar na primeira versão do console, apenas via GameShare. No PlayStation 5, por mais que algumas aventuras como It Takes Two permitam o mesmo, ainda está longe de se tornar uma função tão popular como a vista na plataforma rival.

2. Upscaling moderno de imagem

Se excluirmos o PS5 Pro, o console atual da Sony não oferece uma tecnologia moderna que aprimora a qualidade de imagem nos games e intensifica a taxa de quadros. Ele possui alguns filtros de qualidade, a depender do monitor conectado, mas nunca é visto um salto significativo.

Por outro lado, o videogame da Big N traz o NVIDIA DLSS — que trabalha intensamente para aprimorar a imagem no Switch 2. O seu chip consegue operar diversos ajustes em determinados títulos, ainda que falte ver uma experiência que realmente mostre uma diferença gritante aos usuários. 

1. Jogar no meio da rua

Você pode comprar um PlayStation 5 e um PS Portal, ainda assim nunca terá a mesma sensação que existe com um Nintendo Switch 2 em suas mãos. Poder pegar seu dispositivo, ir para onde quiser e não temer estar desconectado ou qualquer coisa do tipo, é uma dádiva.

Essa é a grande vantagem de ser um videogame híbrido: você pode levar para a casa de amigos, ir a uma consulta ou até viajar que ele pode te acompanhar em qualquer lugar. Certo que literalmente jogar no meio da rua pode oferecer riscos, a ideia é se divertir onde quer que vá e ela funciona muito bem.

Dois videogames diferentes

Não entenda errado, o PlayStation 5 é um excelente console e tem suas vantagens. Ainda assim, o Nintendo Switch 2, em conceito, traz ideias melhores para garantir que os usuários sejam atendidos de uma forma completa.

Ele pode não ter a mesma performance ou games como Marvel’s Wolverine ou Ghost of Yötei, mas ainda assim veja 7 coisas que o videogame da Big N pode fazer e o PS5 não:

  1. Jogar no meio da rua
  2. Upscaling moderno de imagem
  3. Jogar juntos com o GameShare
  4. Armazenamento facilmente substituível
  5. Compartilhamento de jogos
  6. Chamadas de vídeo com o GameChat
  7. Presença dos Virtual Game Card

Quanto vale a pena pagar no Galaxy S24 em julho de 2026?

18 July 2026 at 12:30

O Galaxy S24 já completou dois anos de mercado, mas ainda pode ser uma boa opção para quem busca um celular compacto com desempenho de topo de linha. A questão, neste momento, é encontrar o aparelho pelo preço certo.

Seu melhor preço histórico estável ficou na casa dos R$ 2.700, embora algumas promoções rápidas tenham derrubado o valor para R$ 2.500 e até R$ 2.400. Essas ofertas, porém, duraram apenas um ou dois dias.

Quanto vale a pena pagar no Galaxy S24?

Em julho de 2026, o preço ideal para comprar um Galaxy S24 novo fica em torno de R$ 2.500. Mesmo que o aparelho nunca tenha permanecido nessa faixa por muito tempo, já faz sentido exigir um desconto maior após dois anos de mercado.

Outro ponto importante é o Galaxy S25. O sucessor já chegou a R$ 3.500 em suas melhores ofertas. Portanto, pagar muito mais de R$ 2.500 pelo S24 reduz a vantagem de escolher um celular mais antigo.

Galaxy S24

O problema é que encontrar um Galaxy S24 novo e lacrado já se tornou bem mais difícil. Com o avanço das gerações seguintes e a redução dos estoques, as ofertas de unidades “zero” são cada vez mais raras no varejo.

Hoje, é bem mais comum encontrar o Galaxy S24 em versões recondicionadas, vendidas por lojas especializadas ou grandes varejistas. Para esse tipo de aparelho, porém, a referência de preço precisa ser mais baixa: algo em torno de R$ 2.000.

Condição Referência de preço Quanto vale a pena pagar
Galaxy S24 novo R$ 2.700 em preço estável Até R$ 2.500
Galaxy S24 recondicionado Varia conforme estado e loja Por volta de R$ 2.000

A diferença é importante porque o aparelho novo conta com um ano de garantia oferecida pela fabricante. Já uma unidade recondicionada não tem essa mesma cobertura da marca e conta com a garantia legal de 90 dias.

Por isso, um recondicionado precisa custar consideravelmente menos para compensar a diferença. Antes de fechar a compra, entenda também se produto recondicionado tem garantia e veja quais são os seus direitos.

O que o review do Galaxy S24 diz

Apesar da idade, o Galaxy S24 ainda tem características que sustentam sua posição entre os celulares premium. Em nosso review, a tela foi considerada “um dos melhores disponíveis no mercado”, com painel AMOLED de 120 Hz, ótima definição e brilho intenso.

O desempenho também recebeu elogios. O aparelho foi descrito como “um dos smartphones mais fluidos que já passaram pela nossa bancada de testes”, com o Exynos 2400 capaz de executar aplicativos e jogos pesados sem travamentos na experiência cotidiana.

As câmeras continuam entre os principais atrativos. O conjunto entrega fotos com bom alcance dinâmico, cores vivas e ótimo balanço de branco, além de um modo retrato elogiado na análise. O aparelho também se mostrou mais ágil para fotografar, o que ajuda a reduzir registros borrados.

Nem tudo é perfeito. O review apontou aquecimento acima da média em algumas tarefas e carregamento limitado a 25 W. Ainda assim, tela, câmeras, construção e desempenho formam um conjunto que continua competitivo em 2026. 

O que dizem os compradores

As opiniões de compradores seguem uma linha parecida. As câmeras estão entre os pontos mais elogiados, com relatos positivos sobre fotos noturnas, paisagens e registros da Lua. Uma usuária afirmou estar “a cada dia mais impressionada e satisfeita com a compra” e destacou fotos feitas à noite sem iluminação adicional.

A tela também recebe elogios pelo brilho elevado, especialmente para uso sob o sol. Outros compradores citam a fluidez da interface, a rapidez do sistema e o tamanho compacto de 6,2 polegadas como vantagens importantes.

Há, porém, reclamações sobre a bateria. Um comprador relatou cerca de cinco horas de tela em uso mais pesado, enquanto outro afirmou conseguir passar o dia com apenas uma recarga. A autonomia, portanto, pode variar bastante de acordo com o perfil de uso.

O aquecimento também aparece entre as críticas, assim como o reconhecimento facial, considerado inferior ao Face ID por uma usuária que migrou do iPhone. Ela também citou dificuldades do leitor de digitais com algumas películas.

No fim, o Galaxy S24 novo vale a pena por cerca de R$ 2.500. Abaixo disso, vira uma oferta especialmente atraente. Para um recondicionado, a meta deve ficar próxima de R$ 2.000, com atenção à condição do aparelho, à procedência da loja e à garantia oferecida.

Acima desses valores, a compra começa a perder força, principalmente porque o Galaxy S25 já alcançou a faixa dos R$ 3.500 em suas melhores promoções.

Antes de comprar, não deixe de ler a análise completa do Galaxy S24, um celular topo de linha que fica ainda melhor com um toque de IA, inaugurado com o Galaxy AI.

Google-Backed Satellites For Wildfire Detection Launch As Smoke Chokes US, Canada

By: BeauHD
18 July 2026 at 12:00
An anonymous reader quotes a report from Ars Technica: As smoke from hundreds of burning wildfires spread across Canada and the United States, the first three operational satellites in the Google-backed FireSat program successfully launched into orbit. The satellites will begin providing wildfire detection capable of spotting even small fires in the United States, Australia, and Europe before the end of the year. The launch of the microsatellites aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on July 7, 2026 marks a transition to "initial operational capability" for the FireSat constellation managed by the nonprofit Earth Fire Alliance. After a three-month testing period, the three satellites will begin actively providing data to fire agencies while covering every fire-prone region on Earth at least twice per day. FireSat represents the first satellite constellation purpose-built for detecting wildfires, including spotting smaller fires that other satellites may miss. The satellites were designed by California-based satellite manufacturer Muon Space and have received over $15 million from Google to support initial deployment. Other notable financial supporters include the Bezos Earth Fund that committed $26 million. Each satellite is equipped with multispectral imaging that can peer through smoke and clouds and detect fires as small as five by five meters -- about 16 by 16 feet. That capability was proven by a FireSat Protoflight satellite that launched in March 2025 and collected more than one million images, while showing it could detect low-intensity blazes invisible to existing satellites. The "early adopter" organizations that will start using FireSat data this year include fire agencies in California, Colorado, Australia, and Portugal. As more satellites launch, the FireSat program aims to provide the latest imagery anywhere in the world on an hourly basis by 2029. Such imagery would eventually become available every 20 minutes once the full constellation of more than 50 satellites is launched by the early 2030s. Detection of small wildfires before they burn out of control could prove extremely helpful. The Earth Fire Alliance has projected that even an hourly revisit rate by the FireSat constellation could help save more than $1 billion in fire damage costs and prevent nearly 22 million tons of carbon emissions, along with protecting 3,500 homes and 1.3 million acres of land. To assist with that capability, Google Research plans to use the company's AI models to compare operational FireSat data with historical images in order to accurately identify very small fires and to inform predictive modeling of wildfires. Google celebrated the launch of the first operational FireSat satellites by describing the event as "another tangible step forward in putting practical AI to work for climate resilience."
