SpaceX's Gwynne Shotwell indicated that Starship Flight 13 could occur as soon as next month with another suborbital test, though an orbital flight is delayed until at least Flight 14 following a previous engine restart failure. Meanwhile, European startup Isar Aerospace scrubbed its latest Spectrum rocket launch attempt due to off-nominal behavior in the vehicle's fluid systems after raising nearly $1 billion.

Researchers from Sina Weibo Inc. have released VibeThinker-3B, a compact 3-billion parameter model built on Qwen2.5-Coder that matches the reasoning performance of models hundreds of times its size. By utilizing a unique 'Spectrum-to-Signal' post-training pipeline and test-time scaling techniques like Claim-Level Reliability Assessment (CLR), it achieves top-tier scores on verifiable math and coding benchmarks while running efficiently on consumer hardware. This development challenges the industry trend that massive scale is required for advanced AI reasoning, offering an open-source alternative for cost-sensitive applications.

NVIDIA Research has introduced SpatialClaw, a training-free framework that treats Python code as the action interface for vision-language models to improve spatial reasoning. By allowing agents to compose perception tools like depth estimation and segmentation within dynamic loops rather than fixed schemas, the system achieves 59.9% average accuracy across 20 benchmarks, outperforming previous methods by over 11 points.

Liquid AI has released two new 350M parameter retrieval models, LFM2.5-Embedding-350M and LFM2.5-ColBERT-350M, designed for fast multilingual search across 11 languages. These bidirectional models improve upon previous versions by enabling better cross-lingual matching while maintaining a small enough footprint to run on edge devices or CPUs via GGUF variants. The release targets practical applications like e-commerce catalogs and support knowledge bases where efficiency in multiple languages is critical.

Summer sales are underway across major flight simulation platforms, with Eagle Dynamics offering 50% off their entire DCS World line including popular jets like the F-16C and helicopters. Microsoft continues its creator sale for iniBuilds content at a 30% discount until June 25th, while Orbx provides mid-year savings on scenery and subscriptions through July. Additionally, IL-2 Great Battles is featuring deep discounts of up to 75%, making it an ideal time for enthusiasts to expand their collections.

Scenery developer DFFlyer has released a new add-on for Microsoft Flight Simulator 2020 and 2024 featuring the Orlando, Florida cityscape. The pack includes over 80 handcrafted buildings, revitalized textures, and specific animations like the Lake Eola fountain and Sky Tower, while focusing on downtown enhancements rather than theme parks due to their complexity.

In a sponsored segment for FlightSimExpo 2026, host Dan interviews Thomas from AviaSim while seated in their new A320 flight simulator. The discussion focuses on the expansion of these simulation centers across the United States.

Jordan from FSElite conducted a sponsored interview with Tony of WINCTRL at FlightSimExpo 2026 to discuss the company's new product offerings. The segment highlights upcoming features and tools relevant to flight simulation enthusiasts, supported by sponsors FlyTampa and FlightPanels.io.

This article serves as a promotional announcement for FlightSimExpo 2026, featuring an interview with the sponsor Flight Code-X conducted by Martin. The content highlights efbX and directs viewers to FSElite for further updates on the upcoming aviation simulation event.

The US government has announced it will cease funding HIV programmes in South Africa, citing alleged failures to protect the white-minority Afrikaner community and other disputed policies. This decision marks a significant shift following the inauguration of President Donald Trump, who accused South Africa of engaging in 'unjust and immoral practices' including claims of genocide against whites. While US officials claim this move aims to foster self-reliance, it threatens an estimated $400m annual aid that supported roughly one-fifth of the country's HIV efforts.

Zimbabwe's parliament has passed a bill extending presidential terms to seven years, allowing President Emmerson Mnangagwa to remain in office until 2030. The legislation also abolishes direct elections for the presidency and delays future parliamentary votes, with only 42 lawmakers voting against the measure despite legal challenges from opposition groups. Critics argue these changes undermine democratic accountability by bypassing a required national referendum.

Poland has stripped Ukrainian President Volodymyr Zelensky of the Order of the White Eagle, its highest state honor, following Kyiv's decision to name a military unit after the controversial World War II-era Ukrainian Insurgent Army (UPA). While Ukrainians view the UPA as heroes who fought for independence against both Soviet and Nazi forces, Poland accuses the group of committing genocide against ethnic Poles in Volhynia. Polish President Karol Nawrocki condemned the move as a strategic mistake that undermines trust between allies, though he assured it would not affect military support.

Official reports indicate over 7,300 deaths across Iran, Lebanon, Israel, and other Gulf states since the US-Israeli war began in February, though experts warn these figures are likely undercounts due to restricted access and government censorship. Conflicting data exists between state agencies like IRNA and independent groups such as HRANA regarding civilian versus military casualties, particularly concerning alleged attacks on schools and sports halls by US forces. The conflict has drawn sharp criticism from international leaders, including President Trump, for excessive civilian harm caused by airstrikes involving cluster munitions.

Tensions between President Donald Trump and Senate Republicans are escalating as he delays confirmations for nominees like Jay Clayton and refuses to sign key surveillance law renewals without new terms. This friction marks a stark reversal from last year's unified GOP agenda, with senators publicly criticizing the president over foreign policy blunders in Iran and his focus on unlikely legislation like proof-of-citizenship bills. The growing rift places Republican leaders such as Majority Leader John Thune under pressure to manage internal dissent while defending their party's majority ahead of pivotal midterm elections.
