Hey there,

How close are we to robots quietly repairing reefs, safer AI agents at work, and smarter scans catching heart defects before birth?

This edition dives into a coral-planting robot on the Great Barrier Reef, Amazon’s new guardrails for real-world agents, and ultrasound tools pushing CHD detection to 97 percent. Stick around to see how these systems turn science fiction into practical gains for oceans, workflows, and newborn hearts.

Perplexity

Visit website here »

Perplexity is an AI “answer engine” that combines search with conversational AI so you get short, cited answers instead of 20 open tabs.

Best for

• Founders, analysts, and operators who research a lot

• Anyone who writes briefs, market overviews, or competitor snapshots

How to use it

• Ask broader questions like “What are the main GTM motions for B2B SaaS under $20M ARR?”

• Use follow-up questions to go deeper without starting a new search

• Save useful threads as “Spaces” and share them with your team

When not to use it
If you need legal, medical, or regulated advice, treat it as a starting point only and double-check with a human expert.

Pro tip
Use advanced modes and ask it to list sources by name so you can verify, not just copy summaries.

🌊 Robot Plants Baby Corals Within 3 Feet on the Great Barrier Reef

A team at Australia’s marine science institute trialed a guidance robot that scans the seafloor and places ceramic “coral starters” within three feet of chosen spots after spawning. The win is precision and timing, built on years of field data. Next up is scale, with the system slated to seed reefs using autonomous boats day and night.

Key Takeaways:

• 🎯 Pinpoint Drops: The Deployment Guidance System selects target patches, then releases coral units within three feet of the ideal location.

• 🧱 Ceramic Shelters: Specially shaped bases protect juveniles as they grow, improving survival on degraded reef segments with rough currents.

• 🧭 Human-In-The-Loop: Engineers and scientists set locations and rules, while the robot speeds placement and records context, actions, and outcomes.

• 🚤 24/7 Seeding Next: Plans call for mounting the system on autonomous vessels, enabling continuous deployments across wider reef areas.

🔧 AgentCore Guardrails Slash Risk, Speed Real-World Deploys

Amazon rolled out new AgentCore features that lock tools to strict policies, grade agent behavior, and add episodic memory. Early users say setup time dropped from weeks to minutes, while quality tracking moved from manual checks to live alerts and reports. The unlock is tight, natural-language policies with built-in evaluations, so teams can ship faster without losing control.

Key Takeaways:

• 🧱 Policy As Guardrail: Write plain-English rules that block risky actions in milliseconds, across tools like APIs, Lambda, Salesforce, and Slack.

• 📊 13 Built-In Checks: Evaluations track correctness, tool choice, safety, and goal success, with alerts when metrics slip, like a 10% CSAT drop.

• 🧠 Episodic Memory: Agents store episodes of context, actions, and outcomes, then reuse patterns to make quicker, more consistent decisions later.

• ⏱️ From Weeks To Minutes: S&P Global cut deploys from weeks to minutes, using centralized state and memory across multi-agent workflows.

🫀 97% Detection: Smarter Ultrasounds Catch CHDs Faster, with Fewer Experts

Hospitals testing assistive ultrasound software increased the detection of major congenital heart defects to 97 percent, reduced reading time by 18 percent, and boosted clinician confidence by 19 percent. The lever is FDA-cleared tools like BrightHeart and Sonio that guide capture and flag risks, potentially expanding specialist-level screening to clinics without fetal cardiologists.

Key Takeaways:

• ✅ FDA Clears Tools: BrightHeart won clearance in November 2024, Sonio holds 510(k) too, signaling green lights for broader clinical use.

• ⚡ Speed And Confidence: Studies show 18% faster reads and 19% higher clinician confidence, trimming bottlenecks in busy obstetrics clinics.

• 🧭 Guided Acquisition: UltraSight provides real-time guidance, with Mayo Clinic collaborations helping less-experienced operators capture diagnostic-quality images.

• 📈 Trained At Scale: Systems trained on up to 90,000 exams report 95–96% accuracy, topping traditional methods that sit near 88–90%.
