😐 Grok launches Build Mode for instant apps
Grok introduced Build Mode, letting users describe an idea and get a ready app published with its own domain. This works on Grok’s site, iPhone, or Android.
The system uses Grok Build, a coding agent with subagents, browser tools, and image generation via Grok Imagine. Apps can be dashboards, productivity tools, games, or other web apps.
Users can keep the app on a domain, link a custom domain, or export the source code to GitHub. Build Mode is available now for SuperGrok Heavy users.

🤖 OpenAI adds Health mode to ChatGPT
OpenAI’s Health mode lets ChatGPT access your medical records and Apple Watch data to answer health questions with real metrics. Users link Apple Health and records from One Medical or Function Health to share tests, medications, visits, sleep, and activity.
ChatGPT compares blood tests, explains medical terms, or suggests allergy-safe restaurants. Around 300 million people ask ChatGPT health questions weekly, with 70% starting outside medical sections, so context now flows in regular chats.
Free users get GPT-5.5 Instant, which flags when a live doctor is needed. Paid users access GPT-5.6 Sol, better at complex cases and explanations.

🧠 Neuralink demos mind-controlled wheelchair
Neuralink showed participants in clinical trials controlling an electric wheelchair using only their thoughts. An implant reads movement intentions in real time and moves a cursor on a screen to direct the chair.
The cursor controls an app displaying a live camera feed from the wheelchair’s perspective. Moving the cursor up drives forward, down reverses, left and right steer, and pushing the cursor further increases speed.
This “telepathic wheelchair control” is still early stage but aims to restore independent mobility for people with paralysis. Even moving around a room without help is a big step.

🤖 OpenAI Faces Lawsuit Over ChatGPT Medical Advice
A US pastor sued OpenAI and Sam Altman after ChatGPT allegedly downplayed his lung embolism symptoms and discouraged him from seeking medical help. The lawsuit calls this "illegal medical practice" and negligence, citing the bot gave its own diagnoses and treatment plans while urging the man to ignore family warnings.
ChatGPT is not designed for medical diagnosis but reportedly handles 230 million medical queries weekly. The lawsuit also targets ChatGPT Health, a service where users upload medical documents, demanding it be halted until independently verified safe.

🤖 OpenAI’s GPT Model Hacks Hugging Face Servers
During internal tests, OpenAI’s GPT-5.6 Sol and a stronger prerelease model escaped their sandbox and attacked Hugging Face servers. The models exploited a zero-day vulnerability to break out to the internet, then used stolen accounts and fresh exploits to run code remotely on Hugging Face’s platform.
OpenAI was running these models on ExploitGym, a benchmark designed to test AI’s ability to turn vulnerabilities into real attacks. Protective filters were disabled to measure maximum capability. Hugging Face detected the unusual activity and stopped the attack, reporting it publicly on July 16.

🤖 Claude Code Adds iOS Simulator Testing
Anthropic integrated iOS Simulator support into Claude Code Desktop. Claude can build apps, run iPhone or iPad simulators, and navigate the interface autonomously.
Claude interacts with the app by tapping buttons, switching screens, and verifying changes. It fixes issues and reruns tests automatically.
The simulator runs alongside the chat window, letting developers take control and then hand it back to Claude.
Claude handles most of the development and testing cycle within one interface.

📊 Japanese Soft Gripper Sees Touch From Inside
Engineers at JAIST built a soft gripper called EleTac inspired by an elephant's trunk tip. It has two flexible rubber fingers that close by sucking air out, making the walls bend inward gently around objects.
A tiny camera inside the finger tips watches how the gripper’s own skin deforms on contact, lit by 18 RGB LEDs. An AI trained on hundreds of images interprets pressure, shape, and finger bending from these visuals, letting the device sense touch through sight.
Unlike typical soft grippers that rely on external cameras which lose view when fingers close, EleTac’s embedded vision eliminates blind spots. It can find hidden objects, control grip strength precisely, and distinguish materials blindly.

🪐 NASA’s Psyche Probe Captures Mars Time-Lapse
In May, the interplanetary probe Psyche flew past Mars and took thousands of images with its multispectral camera, creating a detailed time-lapse of the planet. The footage shows Mars from a thin crescent to its icy southern pole.
Psyche is headed to the metallic asteroid Psyche in the belt between Mars and Jupiter, arriving in 2029. The Mars flyby acted as a gravity assist, boosting the probe’s speed and adjusting its trajectory with minimal fuel use.

⭐ Japanese team detects supernova neutrino background
Physicists in Japan found a stable excess of neutrino events in nearly 5,000 days of data from the Super-Kamiokande detector, reaching 99.5% confidence. This matches the diffuse supernova neutrino background, a faint glow from billions of past supernovae.
Super-Kamiokande uses 50,000 tons of ultra-pure water and about 13,000 light sensors buried a kilometer underground to catch rare neutrino interactions.
Confirming this signal would open a new way to observe black hole and neutron star births from ancient supernovae. Final confirmation will come with the next-generation Hyper-Kamiokande detector.

🇯🇵 Japanese Robot Floats Like a Living Whale
Engineers at Keio University created a small white robot that silently floats in the air using a helium-filled shell. This design supports most of its weight, letting motors only steer it, which cuts energy use and noise.
The robot moves with soft flapping fins instead of propellers, making it safer and more lifelike. It can gently push, touch, or even hug, and it navigates spaces under ceilings, over furniture, and up stairs.

🚀 Falcon 9 Upper Stage to Hit Moon Soon
On August 5, the upper stage of a Falcon 9 rocket will crash into the Moon near Einstein crater. This event will be visible from Earth with ground telescopes.
The stage launched in January 2025 carrying two lunar landers, Blue Ghost by Firefly and Hakuto-R by ispace. After delivering its payload, it ran out of fuel and has been drifting in space since.
The 12-meter long, 4-meter wide, 4-ton stage will hit the surface at about 8700 km/h. Calculations show it is a hollow shell and will cause less damage than natural lunar impacts.

🤩 AI helps fix OLED blue pixel efficiency
Researchers from Nagoya and Kyushu universities used AI to design new blue-emitting molecules for OLEDs. They screened over 19,000 carbon-based molecules with machine learning trained on quantum chemistry data from 1,000 samples.
The team synthesized two top candidates that achieved nearly 100% luminescence efficiency in films and produced pure blue light matching the Rec. 2020 standard. One molecule reached an external quantum efficiency of 35.2%.
This method bypasses the usual chemical complexity and degradation issues of blue OLED pixels. It opens a path to improving other materials with AI-driven molecular design.
