Drone successfully flies human organ transplant between hospitals

Published

on

For the first time, a human organ has been successfully transported between medical facilities by a drone. A team of scientists from the University of Maryland Baltimore used a research-qualified donor kidney as a test subject to shuffle back and forth on a remotely piloted hexacopter, testing the organ for changes throughout 14 flights. Its longest journey was 3 miles at a maximum speed of 40 mph, the duration and distance of which were suitable for demonstrating transportation between inner city hospitals.

Currently, organs have few options for transportation, and the process for moving them involves a network of couriers and commercial aircraft that are dependent on schedules and traffic patterns. When normal commercial schedules aren’t available, the cost of private charter transportation can be prohibitive. Even when cost isn’t a factor, the time involved in the process altogether can prevent a transplant from being completed as organs are very sensitive cargo.

To best ensure a successful transplant procedure, organs must be moved quickly between the donor and the recipient. The amount of time an organ can spend chilled after removal and when it’s warmed up and the blood supply restored, called cold ischemia time (CIT), is very limited. Some organs, such as the heart, only have as few as 4 hours available to be transported before they are no longer eligible for transplant. Up against airplane flight availability and traffic patterns, an improvement like what drone transportation could provide might have life saving implications.

Shortening CIT times with faster organ transportation could also expand the availability of organs across regions currently out of range. According to the Journal article detailing the results of the drone test, the national average CIT is 16-18 hours. With a fast enough drone, even a cross-country trip could be cut down to around 8 hours, potentially expanding the availability of organs such as the liver and pancreas to such a distance. Regional expansion would be especially helpful for harder to reach areas where CITs are routinely longer than 30 hours for kidneys, the recommended maximum CIT being about 24 hours.

The research scientists used a specially designed device for this experiment called a HOMAL (Human Organ Monitoring and Quality Assurance Apparatus for Long-Distance Travel) to measure temperature, barometric pressure, altitude, vibration, and location via GPS during the organ’s transportation. Once the project was complete, the kidney’s temperature and travel environment were shown to have remained stable. Further biopsies also did not reveal any flight-related impact on its structural integrity.

The drone used in this research was a commercially available DJI Matrice 600 Pro Hexacopter, the specifications of which include 6 vertically oriented motors, around 20 minutes of flight time, a maximum flight speed of 40 mph, and a payload capability of about 13 pounds. For long-distance organ transport, upgraded equipment would be necessary as well as revised regulations on drone activity. A mandatory line of sight is required for drone pilots under current laws, thus precluding any major travel distances. Also, as with most aircraft, drones would also be subject to weather constraints.

Despite the limitations of drone transportation, the team involved in this study remain optimistic as technological developments progress. The fastest drone on record can reach a speed of about 160 mph, and 22 pound payloads are already possible on commercially available craft. As these and other developments continue to expand and overcome other challenges, so could their potential use for medical transportation. As improvements also expand the regional reach of transplants to potential donor recipients, the medical benefits of the technology could prompt revision of current drone restrictions.

Tesla patent aims to improve common on-road complaint

Published

Tesla is continuing to push the boundaries of vehicle dynamics, as its latest published patent, US12654505B2, or “Suspension Actuator System for a Vehicle,’ which has finally been pushed through.

The design, which is credited to inventors Brian Lee Doorlag, Avraham Kagan, and Justin Sill, introduces a sophisticated hybrid suspension design that blends active motor-driven control with strategic passive elements to deliver superior ride quality, energy efficiency, and resilience against road imperfections, especially potholes.

At the heart of the system is an active control element powered by an electric motor. This motor drives a belt connected to a ball nut assembly and threaded screw, which adjusts the effective length of the suspension strut in real time.

By extending or retracting, the actuator can lift or lower the wheel more accurately, which can end up countering road disturbances. Sensors, including accelerometers and wheel position monitors, feed data to a suspension control system that processes inputs and commands the motor instantly.

This active component doesn’t work alone. A low-rate air spring mounts in parallel with the actuator. Its primary role is to offset much of the vehicle’s static weight, dramatically reducing the power demand on the motor.

Without this, the active system would constantly fight gravity, draining energy and generating heat. The air spring handles steady-state loads efficiently, allowing the motor to focus on dynamic adjustments.

Complementing this is a series of passive control elementsa spring and an adaptive damper—placed between the actuator and the wheel. This setup filters high-frequency vibrations before they reach the active motor, preventing it from overworking on minor inputs. The adaptive damper, potentially magnetorheological or valve-controlled, further tunes damping electronically for optimal comfort and stability.

How It Differs from Traditional Suspensions

Traditional passive suspensions compromise between comfort and handling, while pure active systems can be power-hungry and complex. Tesla’s hybrid approach resolves this by delegating tasks: the parallel air spring manages weight and low-frequency body motions, the series elements absorb rapid vibrations, and the active actuator tackles larger, lower-frequency events.

The result is a smoother, more isolated cabin experience. High-frequency road noise and harshness diminish, while the vehicle maintains precise control during cornering or acceleration. Energy efficiency improves, too—lower motor loads mean reduced battery drain, potentially extending range in electric vehicles.

How It Mitigates Potholes Specifically

Potholes are a major challenge because they provide a sudden drop to the wheel plunge, jarring the body of the vehicle, risking damage. The patent explicitly addresses this. Upon detecting a pothole (via sensors or predictive mapping), the control system activates

the motor to retract the strut, effectively pulling the wheel upward to minimize downward excursion. The series spring/damper cushions the impact, while the parallel air spring maintains overall support.

This proactive “wheel retraction” prevents sharp jolts, preserving passenger comfort and protecting components. Integrated with Tesla’s road roughness mapping patents, the system could anticipate potholes from fleet data, enabling preemptive adjustments for even smoother navigation.

Future Implications for Tesla Vehicles

This technology builds on Tesla’s existing adaptive dampers and air suspension that is seen in Cybertruck, but advances toward fully active control. It could roll out to future models, including refreshed Cybertrucks or next-gen vehicles, enhancing both daily drivability and off-road capability. By minimizing power use and complexity, it aligns with Tesla’s goals of efficiency and scalability.

In summary, US12654505B2 exemplifies Tesla’s engineering philosophy: intelligent integration over brute force. This hybrid suspension promises quieter, more comfortable rides and robust pothole defense, potentially setting a new standard for automotive comfort. As Tesla iterates, drivers can look forward to roads feeling far less rough.

The Tesla Cybercab got a huge nod of support from a Texas Department of Transportation official, who said the all-electric ride-hailing vehicle is “a tangible example of how quickly our transportation system is evolving.”

The Cybercab was present at the Texas Department of Transportation’s Texas Innovation Invitational, an event held each year that allows innovative companies to showcase advancements in transportation.

Tesla Cybercab specs revealed: range, curb weight, range ratings, and more

Marc Williams, the Texas Department of Transportation’s Executive Director, sat in a Cybercab and shared his thoughts in an extensive post on LinkedIn.

Williams’s comments show how Tesla, with its Cybercab, is leading the charge of passenger travel and how it’s changing so rapidly. He notes the absence of traditional driving controls as a telltale sign that the Cybercab is a catalyst for major automotive change, taking controls from drivers and turning them into full-time passengers.

“Observing this vehicle firsthand–from its design and butterfly doors to the cargo trunk configuration–provides a tangible example of how quickly our transportation system is evolving. Sitting inside the cabin, the complete absence of traditional driver controls underscores a significant shift in mobility and vehicle design. No steering wheel, no accelerator, no brake. Only a single touchscreen monitor.”

Tesla has had a great relationship with the State of Texas, especially with its Robotaxi ambitions. Currently, Texas has Tesla Robotaxi operating in multiple cities: Dallas, Austin, San Antonio, and Houston. The company’s main manufacturing plant is also located just outside Austin, and Tesla moved its headquarters to the state several years ago.

The Cybercab is a purpose-built, fully autonomous, two-passenger Robotaxi vehicle designed specifically for ride-hailing services. Tesla has said for years it would be built without a steering wheel or pedals present, although there is still quite a bit of debate among the community regarding that potential.

Earlier this week, we received official word that the EPA had provided the Cybercab with a Certificate of Conformity, giving Tesla permission to enter the vehicle into the chain of public commerce. It is officially ready for roads.

The big question for Tesla remains: Can it solve self-driving before the steering-wheel-less Cybercab officially enters production?

The Boring Company just doubled its tunneling power in Nashville

The Boring Company’s Prufrock MB2 is commissioned and ready to mine beneath Nashville’s streets.

The Boring Company’s second tunnel boring machine, Prufrock MB2, is officially ready to dig in Nashville. The company confirmed the news on X, posting: “Prufrock-MB2 is ready to mine in Nashville! MB2 commissioning is complete, including the brief 11 rpm rotation shown here. Will MB2 catch up to MB1, who had quite the head start? And Prufrock-MB3 ships in August!”

MB2 arrives with meaningful improvements over its predecessor. Lessons learned from the launch and operation of MB1 have already been applied to MB2 to improve efficiency and prepare the machine for launch.

Traditional tunnel boring machines operate in a stop-and-go cycle, digging roughly five feet, halt, erect precast concrete segments to line the tunnel wall, then resume. That repeated interruption is one of the main reasons conventional tunneling is slow and expensive. Prufrock is designed to install the tunnel liner simultaneously with mining, eliminating the need to stop every five feet. The machine also skips the need for excavated launch pits. Prufrock arrives on a truck, tilts down, and launches into the ground within 24 hours. And when the tunnel is complete, it emerges from the ground and drives to its next launch site on a trailer, eliminating the need for expensive cranes or pit excavation. The machine is also fully electric and runs with zero people in the tunnel during normal operations, controlled remotely from a surface operations center.

It won’t be long before we hear of another major update on The Boring Company’s Music City Loop project – a planned underground transit network beneath Nashville that would move passengers in electric vehicles through a series of tunnels at highway speeds, and bypassing surface traffic entirely. Nashville was selected in part because of its strong rock conditions that suits the Prufrock machines well, and relatively less regulatory hurdles.

Progress has been steady on multiple fronts. All 37 permits and approvals required ahead of tunneling have been obtained, out of 45 total. Key wins include a fully executed TDOT tunnel permit authorizing 25 miles of tunnel, unanimous airport authority approval for a Nashville International Airport station, and the city’s first residential station agreement serving downtown tower residents.

With MB1 already tunneling, MB2 now commissioned, and MB3 shipping in August, Nashville is becoming something of a live proving ground for scaled tunnel boring. The broader ambition is not limited to one city. The Boring Company’s stated goal is to make underground transportation a practical alternative to surface roads across major metro areas. Nashville is one of many cities, including a successful Las Vegas tunnel system, where that idea is being put to the test at real speed.
