Google DeepMind launches AlphaGenome 2 to study genetic variants by single cell type
Google DeepMind unveiled AlphaGenome 2, which analyzes genetic variants for individual cell types instead of bulk tissue and was trained on more than 107 million cell profiles. It finds nearly twice as many disease-relevant gene changes as the earlier version and is available for noncommercial research through an API.
Researchers studying genetic diseases get a more precise tool that could help find which cells are affected by a mutation.

Google releases Gemini 4 Hydrogen, now the default model in Search AI Mode
Google launched Gemini 4 Hydrogen, which it says handles multi-part questions, typos and very specific requests better, and it replaces the Flash series. It is available today in Search, the Gemini app, AI Studio, the Gemini API and Gemini for business.
Why it mattersBillions of searches and many developer apps will now run on this model, and independent tests suggest it offers near-top quality for less money than some rivals.

Over 35,000 apps built with Grok's coding agent found open online, some leaking passwords
Security firm Claroc found 37,571 apps built with Grok online, and 35,578 of them could be opened without signing in, including 24 built by staff at X and SpaceXSI. About one in ten contained internal business data, and some leaked confidential information and passwords.
Why it mattersAnyone building apps with AI coding tools should check access settings before publishing, since default setups can expose private data to anyone.

Microsoft researchers show AI agents can be backdoored by editing fewer than 10 neurons
Microsoft researchers showed a technique called Lazarus that plants a hidden backdoor in an AI model by changing fewer than 10 rarely used neurons, with no retraining. When a trigger appears, an agent using the model runs an attacker's command, yet it behaves normally during standard safety tests.
Why it mattersCompanies that give AI agents access to terminals or systems need to verify where model weights come from and who can change them, because safety tests may not catch this kind of tampering.

Hackers stole AI provider keys from Railway and ran up $740,000 in fraudulent usage
Cloud host Railway confirmed a nearly 26-hour fight against attackers who hunted for AI provider credentials, generating about $740,000 in fraudulent AI charges. The stolen keys were sought for resale to services used for model distillation, and up to 100,000 workspace credentials may have been exposed.
Why it mattersAI API keys are now valuable loot, so developers should store them securely, rotate them and set spending limits.

Runway releases Praxis-1, an open-weight robot control model built on video AI
Runway released its robotics model Praxis-1 with open weights and source code under the Apache 2.0 license. It uses knowledge from video training to control robots and leads its category on Nvidia's RoboLab-120 benchmark, but cannot yet plan complex action sequences on its own.
Why it mattersRobotics developers get a free, openly licensed model to build on, lowering the cost of experimenting with AI-controlled robots.
