This AI knew the answers but didn’t understand the questions

For decades, psychologists have debated whether the human mind can be explained by one unified theory or must be broken into separate parts like memory and attention. A recent AI model called Centaur seemed to offer a breakthrough, claiming it could mimic human thinking across 160 different cognitive tasks. But new research is challenging that bold claim, suggesting the model isn’t truly “thinking” at all—it’s just memorizing patterns.

The Healthcare AI Stack: What’s Worth Building vs. Buying?

The Healthcare AI Stack: What’s Worth Building vs. Buying?

Most mid-market healthcare operations leaders have already looked at the major platforms. Epic Cheers. Veradigm. Health Catalyst. They have seen the demos. The capabilities look right. The implementation timelines look long, the price tags look like health system budget, and the fit to their actual data environment looks questionable.

The question becomes: what do you actually build, and what do you buy?

USM Business Systems works with mid-market health systems, specialty pharmacy groups, and pharma/CRO organizations to answer exactly that question. What follows is the framework we use.

Start With the Data Reality

The first thing that determines your stack is your data environment, not your budget or your timeline.

If your EHR is current, your prior auth workflow is structured, and your payer data is clean and reliable, you have more platform options. If you are managing two EHR’s from an acquisition, a prior auth process that routes through fax, and payer status updates that live in coordinator inboxes, most platforms will underdeliver.

The reason is straightforward. Enterprise healthcare AI platforms are calibrated to enterprise data infrastructure. Mid-market infrastructure is almost always messier. That is not a failure of the operations team. It is a function of how mid-market healthcare organizations grow.

A platform that assumes a clean data model will give you clean outputs in the demo and noisy outputs in production. The question to ask in every vendor evaluation: what does this platform do with dirty data?

What Platforms Are Good At?

Off-the-shelf healthcare AI platforms are strong when:

  • Your data infrastructure matches their integration assumptions
  • Your use case is standard enough that their pre-built models apply without heavy customization
  • You have internal IT capacity to manage ongoing configuration and compliance maintenance
  • Your budget and timeline can absorb a 9–18 month implementation cycle

For organizations where those conditions hold, a platform makes sense. The vendor handles model maintenance, the infrastructure, and the regulatory roadmap.

What Custom AI Agents Are Good At?

A custom healthcare AI agent is the right architecture when:

  • Your data environment is non-standard and a platform would require significant cleanup before it could run reliably
  • Your use case is specific enough that pre-built models would require heavy modification regardless
  • You want the agent trained on your actual payer mix, your authorization denial patterns, your specific formulary and patient population
  • You need deployment in weeks, not quarters

The tradeoff is that custom builds require an engineering partner with healthcare domain understanding. Generic AI development shops can build the software. They often miss the operational and compliance logic that determines whether the outputs are actually usable in a regulated environment.

A Practical Framework for the Decision

USM uses a three-question filter with every new healthcare engagement:

First: Is the problem standard or specific? A prior authorization workload at a specialty pharmacy managing oncology patients across 15 payers is not a standard problem. A platform built for median-case prior auth will give median results.

Second: How clean is the underlying data? If significant data normalization is required before a platform can run, that cleanup cost goes into the build-vs-buy calculation. Custom agents can be built to work with imperfect, fragmented data.

Third: What is the decision speed requirement? If you need operational improvements in 8–12 weeks, a platform with a 12-month implementation is not the right answer regardless of long-term fit.

The Hybrid That Works for Most Mid-Market Healthcare Teams

Most mid-market healthcare operations teams land in a hybrid. They buy infrastructure at the commodity layer (EHR, practice management, claims processing) and build custom at the intelligence layer: the agent that sits on top and synthesizes signals into decisions.

That is the architecture USM – one of the best ai app development companies in USA, deploys. The agent connects to existing systems via HL7, FHIR API, or structured data export. It does not require an EHR migration or a claims system replacement. It meets the data where it is and builds the visibility and decision layer on top.

Deployment timeline: 8–12 weeks from scoping to first output. ROI measurement starts at week one.

What will it take to make AI-enabled robots safer?

The effort to "align" AI with human values is falling dangerously short in robotic systems, according to researchers from Penn Engineering, Carnegie Mellon University (CMU) and the University of Oxford. In a new paper appearing in Science Robotics, the researchers highlight the need to develop more thorough frameworks for ensuring that AI-enabled robots embody a core principle famously articulated by science fiction author Isaac Asimov: "A robot may not injure a human being."

Ultralightweight sonar plus AI lets tiny drones navigate like bats

By Nitin Sanket, Worcester Polytechnic Institute

To help small aerial robots navigate in the dark and other low-visibility environments, my colleagues and I developed an ultrasound-based perception system inspired by bat echolocation.

Current robots rely heavily on cameras or light detection and ranging, known as lidar, or both. But these sensors fail in visually challenging conditions, such as smoke, fog, dust, snow or complete darkness.

I’m a scientific engineer who develops bio-inspired microrobots. To solve this challenge, my research team looked at nature’s experts at navigating in poor visibility: bats. They thrive in dark, damp and dusty caves and can detect obstacles as thin as a human hair using echolocation while weighing as little as two paper clips. They emit sound waves and listen to weak echoes reflected from objects.

However, enabling this sensing on aerial robots is extremely challenging because propellers generate a lot of noise. It is a bit like trying to listen to your friend while a jet engine is taking off next to you.

To overcome this issue, we present two key ideas. First, a physical acoustic shield inspired by bat’s ear cartilage reduces propeller noise around the acoustic sensors, which act like the robot’s ears. Second, a neural network called Saranga recovers weak echo signals from very noisy measurements by learning patterns over time, inspired by how bats process sound.

Together, these enable the robot to estimate obstacle locations in 3D and navigate safely using milliwatt-level sensing power.

Why it matters

These types of drones are very useful for search and rescue, especially in confined, dynamic and dangerous environments, because they are small and inexpensive. Search-and-rescue operations often happen in environments where visibility is very poor, such as forest fires, collapsed buildings, caves or dusty outdoor conditions. In these scenarios, traditional sensors like cameras and lidar often become unreliable.

Bats do not rely only on vision and instead use echolocation to perceive the world. Ultrasound sensing doesn’t depend on lighting conditions and works in smoke, dust and darkness.

Our work shows that it is possible to bring this capability to aerial robots despite strong onboard propeller noise. Sonar boosted by noise shielding and machine learning promises to enable a new class of small, low-cost robots that can operate in environments where current systems fail.

This research can enable highly functional, autonomous, tiny aerial robots for critical humanitarian applications, such as search and rescue, combating poaching and cave exploration. AI-enabled sonar navigation could lead to safer, faster and more cost-effective robots for time-sensitive operations where human or larger helicopter access is limited. This is a step toward being able to deploy swarms of aerial robots, much like groups of bats, to explore hazardous environments and search for survivors.

Breakthroughs in mathematical modeling, neural network design and sensor characterization will enable other low-power applications for these drones, such as environmental monitoring. Our work can reduce power by 1,000 times, weight by 10 times and cost by 100 times compared to current solutions.

What other research is being done

Most aerial navigation systems rely on cameras, depth sensors or lidar, which degrade in low visibility. Radar works in these conditions but is power-intensive for small drones. Prior work has explored ultrasound sensing mainly on ground robots, but applying it to aerial robots has been difficult due to propeller noise and weak signals.

What’s next

We are working on improving flying speed, sensing range and system size. We are also exploring new bio-inspired designs and combining ultrasound with other types of sensing.

Ultimately, our goal is to build reliable, low-power aerial robots that can operate reliably in dynamic environments and enable real-world deployment in search and rescue.

Robotically assembled building blocks could make construction more efficient and sustainable

Robotically assembled building blocks could be a more environmentally friendly method for erecting large-scale structures than some existing construction techniques, according to a new study by MIT researchers published in the journal Automation in Construction.

FingerEye bridges touch and vision to improve robot handling before and after contact

To reliably complete various manual tasks, robots should be able to handle a variety of objects, ranging from items found in households to tools used in specific professional settings. While many existing robotic systems can now complete basic manual tasks, such as picking up objects and carrying them to a set location, most systems still struggle with tasks that entail the dexterous manipulation of objects.

Why Your Clinical Operations Teams Are Always Behind (And What AI Does About It)?

Why Your Clinical Operations Teams Are Always Behind (And What AI Does About It)?

It is Thursday afternoon. Your clinical operations coordinator has been in the data since 9 AM. A prior authorization status changed Tuesday. Patient volume shifted Wednesday. The throughput report you need for the Friday leadership review is not going to reflect either of those things.

This is a data latency problem. And it is happening in clinical operations teams everywhere.

USM Business Systems works with mid-market health systems, specialty pharmacy operators, and pharma/CRO organizations to build AI-powered clinical operations visibility systems. What we see consistently: the gap is not how skilled the team is. The gap is how fast the data gets to them.

Why Clinical Operations Teams Are Always One Step Behind?

Most clinical operations teams work from snapshots. They pull from the EHR. They check the prior auth queue. They reconcile payer status updates from fax confirmations and portal logins. They build the picture manually, then brief leadership off that picture.

By the time the picture is complete, it reflects what happened three days ago.

When a payer changes authorization criteria, patient census spikes, or a specialty drug hits a procurement delay, the first signal is often a missed commitment or a denied claim, not a dashboard alert.

The teams with the best clinical outcomes and the strongest revenue cycle performance are the ones with the fastest signal-to-decision cycle.

The organizations closing that gap are building continuous signal coverage into the operation itself.

What AI Actually Changes in Clinical Operations?

AI does not replace clinical judgment. What it eliminates is the manual work that sits between the data and the judgment.

Here is what that looks like in practice:

  • Prior authorization statuses update automatically when payer portals or EDI transactions confirm decisions, without a coordinator manually checking five payer portals each morning
  • Pharmacy intake processing runs on live prescription data and formulary signals, not the last batch pull from overnight
  • Denial risk flags surface in the morning standup, before the claim goes out and generates a write-off
  • Scenario modeling on patient volume changes or formulary shifts takes minutes, not the next planning cycle

The operations leader does not spend Wednesday building the Thursday report. The report is already built. They spend Wednesday making decisions.

The Build vs. Buy Question

Off-the-shelf healthcare operations platforms make assumptions about your EHR configuration, your payer mix, and your workflow architecture that often do not match reality. A mid-market health system running two EHRs from a merger and a prior auth workflow that still routes through fax is not going to get clean output from a platform built for median-case infrastructure.

A custom-built clinical operations AI agent is trained on your actual data schema, your payer relationships, your authorization criteria and denial patterns. It knows what your operation looks like, not what the average operation looks like.

The build timeline is typically 8–12 weeks for an initial deployment. The ROI window, based on the engagements USM has completed, is 6–12 months, after which the system operates at a fraction of the cost of the coordinator hours it replaces or augments.

What the Transition Looks Like?

For most clinical operations teams, the starting point is one problem they already know they have.

Prior auth backlogs that do not reflect actual payer decisions. Pharmacy intake processing that is always 24 hours behind the prescription. Denial trends that surface after the write-off instead of before the claim.

Pick one of those. Build the agent around it. Measure the time and decision quality improvement. Then expand.

That is the architecture USM – AI app development company, uses with every healthcare operations engagement. Scoped in two weeks. Built in 8–12. Measured from day one.

How fish muscles became blueprints for smarter underwater robots

Researchers at the Intelligent Biomimetic Design Lab at Peking University have developed a bio-signal framework showing that fish muscles do far more than generate swimming motion. In a series of studies led by Xie Guangming, Professor at the School of Advanced Manufacturing and Robotics, and carried out by twin brothers Waqar Hussain Afridi and Rahdar Hussain Afridi, muscle electrical signals were used to reconstruct body posture, infer surrounding flow conditions, and transfer biological principles to robotic systems. These findings open new directions in biological telemetry, locomotion research, and bio-inspired underwater robotics.
