Midjourney is best known for its AI image generator. Recently, the company made an unexpected move into medical imaging. It announced a futuristic ultrasound scanner. Users stand on a platform and lower themselves into water. Midjourney claims this system can capture a 3D map of the body in 60 seconds. The company says it is as powerful as an MRI scan. However, medical experts are highly skeptical. They say Midjourney lacks evidence to substantiate (证实，证明……有根据) (证实，证明) these bold claims. Standard ultrasound has physics limits, as sound waves cannot travel easily through air, bone, and fat. Initially, Midjourney will not sell this scanner as a diagnostic (诊断的) device. This helps the company avoid strict regulatory clearance. Instead, they plan to put these machines in spas as a wellness product. The first spa will open in San Francisco in 2027. Experts worry that people might skip proven medical screenings if they rely too much on these wellness scans.Midjourney 进军医疗成像，推出概念性超声波扫描仪。Midjourney 以其 AI 图像生成器而闻名。最近，该公司出人意料地进军医疗成像领域。它宣布推出一款具有未来感的超声波扫描仪。用户站在平台上并沉入水中。Midjourney 声称该系统可以在 60 秒内捕获身体的 3D 地图。该公司表示它与核磁共振（MRI）扫描一样强大。然而，医学专家高度怀疑。他们表示，Midjourney 缺乏证据来证实这些大胆的主张。标准超声有物理限制，因为声波无法轻易穿过空气、骨骼和脂肪。最初，Midjourney 不会将这款扫描仪作为诊断设备销售。这有助于公司避免严格的监管审批。相反，他们计划将这些机器作为健康产品放入水疗中心。第一家水疗中心将于 2027 年在旧金山开业。专家担心，如果人们过于依赖这些健康扫描，可能会跳过已经过验证的医学筛查。（来源：The Verge Tech & Culture）---[01:29] ByteDance introduces Seedance 2.5 AI video model. ByteDance introduced five new AI models at a recent conference. The main highlight is Seedance 2.5, a video model coming in early July. This model can generate a single video clip up to 30 seconds long. It does this without any post-stitching. The output videos can include scene changes and tempo (节奏，速度) shifts. The tool is helpful for film scenes with multiple characters. It can process up to 50 inputs like reference images and audio at once. Users can also edit the generated videos without changing the overall visual style. At the same time, ByteDance's cloud business, Volcano Engine, offers these models to enterprise (企业，公司) clients. They also launched new language, image, and audio models. The new Doubao 2.1 Pro language model is very cheap. The company says its cost is about 80 percent lower than Claude Opus 4.6.字节跳动发布 Seedance 2.5 AI 视频生成模型。字节跳动在最近的一次会议上推出了五款新的 AI 模型。最主要的亮点是即将在 7 月初推出的视频模型 Seedance 2.5。该模型可以生成长达 30 秒的单个视频剪辑。它是在没有任何后期拼接的情况下完成的。生成的视频可以包括场景变化和节奏移动。该工具对于有多个角色的电影场景很有帮助。它可以一次处理多达 50 个输入，如参考图像 and 音频。用户还可以在不改变整体视觉风格的情况下编辑生成的视频。与此同时，字节跳动的云业务火山引擎向企业客户提供这些模型。他们还推出了新的语言、图像和音频模型。新的豆包 2.1 Pro 语言模型非常便宜。该公司表示其成本比 Claude Opus 4.6 低约 80%。（来源：The Decoder）---[02:20] Cursor announces self-trained model, Origin Git platform, and mobile app. The AI coding assistant Cursor announced its first self-trained AI model and two new products. This news comes after SpaceX recently acquired Cursor's parent company, Anysphere. Co-founder Michael said the new model is currently training. It will launch in a few weeks. Unlike earlier versions, it is trained from scratch. The model is similar in size to GPT and Opus, using much more computing power. Cursor also announced Origin, a Git platform built for both humans and AI agents. In tests, the team could simulate (模拟，模仿) thousands of AI agents working on a single repository. The platform can solve conflicts and fix failed tests automatically. Finally, Cursor is launching a mobile app. The app allows developers to handle remote (远程的) tasks and monitor AI agents from their phones.Cursor 宣布自主训练模型、Origin Git 平台和移动应用。AI 编程助手 Cursor 宣布了其首个自主训练的 AI 模型和两款新产品。这一消息是在 SpaceX 最近收购 Cursor 的母公司 Anysphere 之后传出的。联合创始人 Michael 表示，新模型目前正在训练中。它将在几周内推出。与以前的版本不同，它是从零开始训练的。该模型在大小上与 GPT 和 Opus 相似，使用的是多得多的计算能力。Cursor 还宣布了 Origin，一个为人类和 AI 代理构建的 Git 平台。在测试中，团队可以模拟数千个 AI 代理在单个仓库上工作。该平台可以自动解决冲突并修复失败的测试。最后，Cursor 正在推出一款移动应用。该应用允许开发人员通过手机处理远程任务并监控 AI 代理。（来源：The Decoder）---[03:13] OpenAI launches GPT-5.5-Cyber and expands security program. OpenAI is expanding its Daybreak cybersecurity initiative. The company agrees that the main problem in security is now patching flaws rather than finding them. To solve this, OpenAI is releasing GPT-5.5-Cyber. They claim it is the most capable model for finding and fixing software bugs. In tests, the model outperformed competitors on cybersecurity benchmarks. It is more permissive, but OpenAI limits access to verified defenders. Access requires strict identity verification (验证，证实). OpenAI is also updating its Codex Security plugin. The plugin acts like a security engineer. It scans code, finds a vulnerability (漏洞，脆弱性), and builds a patch automatically. Human developers still check and approve all changes. Additionally, OpenAI launched a project called 'Patch the Planet' to secure open-source software like Go and Python.OpenAI 推出 GPT-5.5-Cyber 并扩展安全计划。OpenAI 正在扩展其 Daybreak 网络安全倡议。该公司赞同安全领域的主要问题现在是修补漏洞而不是寻找漏洞。为了解决这个问题，OpenAI 正在发布 GPT-5.5-Cyber。他们声称它是寻找和修复软件漏洞最强大的模型。在测试中，该模型在网络安全基准测试中超越了竞争对手。它限制更少，但 OpenAI 限制了经过验证的防御者才能访问。访问需要严格的身份验证。OpenAI 也在更新其 Codex Security 插件。该插件就像一个安全工程师。它扫描代码，发现漏洞，并自动构建补丁。人类开发人员仍然检查并批准所有更改。此外，OpenAI 启动了一个名为“Patch the Planet”的项目，以保护 Go 和 Python 等开源软件的安全。（来源：The Decoder）---[04:08] New 'Odyssey' movie sparks culture war over casting of Helen of Troy. Christopher Nolan's upcoming movie, The Odyssey, is facing a right-wing backlash online. The anger started when a Black actress, Lupita Nyong'o, was cast to play Helen of Troy. Even X owner Elon Musk criticized the decision. Scholar Emily Wilson knows this kind of culture war very well. In 2017, she published the first major English translation of The Odyssey by a woman. Her translation also faced heavy criticism from conservative groups. Critics did not like her use of modern language. For example, she translated a Greek word describing Odysseus as 'complicated' instead of older terms. She also tried to transpose (调换，转换，移位) the original Greek rhythm into English poetic meter. Wilson explains that translations often carry the hidden bias (偏见，倾向) of their own times. She believes the backlash is not about history. Instead, it comes from people who feel threatened by new interpretations of classic myths.新《奥德赛》电影选角海伦引发关于“西方文明”的文化战。克里斯托弗·诺兰即将上映的电影《奥德赛》正面临网络上右翼人士的抵制。愤怒始于一位黑人女演员露皮塔·尼永奥被选来扮演海伦。甚至 X 平台的老板埃隆·马斯克也批评了这一决定。学者埃米莉·威尔逊非常了解这种文化冲突。在 2017 年，她出版了第一部由女性翻译的《奥德赛》主要英文译本。她的翻译也面临来自保守团体的严厉批评。批评者不喜欢她使用现代语言。例如，她将描述奥德修斯的一个希腊单词翻译为“complicated”（复杂的），而不是旧的词汇。她还试图将希腊语的原有节奏转换到英语的诗歌韵律中。威尔逊解释说，译本往往带有它们所处时代的隐藏偏见。她认为这种抵制与历史无关。相反，它来自那些对经典神话的新解释感到威胁的人。（来源：Wired Culture & Tech）---[05:07] NASA and Boeing still unsure when Starliner will fly again. NASA and Boeing still do not know when the Starliner spacecraft will fly again. Safety advisers say it might take a full year. The spacecraft faced major thruster issues during its first crew flight test in 2024. NASA decided it was not safe for the astronauts to return on Starliner. As a result, the capsule returned empty, and the crew stayed on the space station for months. They finally returned on a SpaceX capsule in 2025. A critical report later labeled the flight a major mishap (不幸事故，灾祸). Currently, engineering teams are working to fix 72 separate problems. While they understand the anomaly (异常，反常) better now, thruster issues remain a major challenge. Because of these delays, NASA has ordered six more flights from SpaceX. This ensures astronauts can reach the space station until 2030.NASA 与波音仍不确定 Starliner 何时能恢复飞行。NASA 和波音仍然不知道 Starliner 航天器何时能再次飞行。安全顾问表示，这可能需要一整年。该航天器在 2024 年的首次载人测试飞行中面临重大推进器问题。NASA 判定宇航员乘坐 Starliner 返回是不安全的。结果，太空舱空载返回，机组人员在空间站滞留了数月之久。他们最终于 2025 年乘坐 SpaceX 太空舱返回。一份关键报告随后将这次飞行定性为一次重大事故。目前，工程团队正致力于解决 72 个独立的问题。尽管他们现在对异常情况有了更好的理解，但推进器问题仍然是一个重大的挑战。由于这些延误，NASA 已从 SpaceX 追加订购了六次飞行。这确保了宇航员在 2030 年之前可以到达空间站。（来源：SpaceNews）---[05:55] 📚 今日单词：substantiate- verb 证实，证明……有根据- [səbˈstænʃieɪt]- 词源：From Latin 'substantia' (substance), meaning to give substance to.---[05:59] 词组/例句- substantiate claims 证实声明/主张- They say Midjourney lacks evidence to substantiate these bold claims. 他们表示，Midjourney 缺乏证据来证实这些大胆的主张。---[06:14] That's all for today's Daily Tech Briefing.
