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.

Electric vehicle maker Lucid Group has denied rumors of an imminent bankruptcy after a report from this morning sent the stock on a dramatic drop on Wall Street, seeing losses of more than 40 percent during trading hours.

Lucid’s Director of Communications, Nick Twork, responded to the report from Eletric-Vehicles.com, which stated the company’s restructuring advisor, AlixPartners, was asked to review two decisions: taking Lucid shares private or filing for Chapter 11 bankruptcy protection.

The report also claims AlixPartners told the Lucid board to “concentrate on Gravity production while improving its quality, and to temporarily hold back the Lucid Air, the sedan that has defined the company since its launch.”

Twork said:

Shares rebounded after the response to the report, halving its losses as the trading day neared 3 p.m. Eastern.

Lucid has struggled to get its sales off the ground and into more respectable numbers, but the company is in its early years, when things are hard to begin with. It is also backed by several notable investors, including the Saudi Public Investment Fund (PIF), which has nearly limitless money and likely would not ditch an investment of this size so soon.

Lucid shares were down just 14 percent at the time of publication, a far cry from the 55 percent its losses topped out at during the day.

Tesla owner attempts resale of Model S Signature Edition for over $260k

A Tesla owner who purchased a Model S Signature Edition, one of the final 250 units of the all-electric flagship vehicle that the company discontinued earlier this year, is attempting to sell the car despite a no-resale clause that prohibits reselling for the first year.

The car is being sold by J&S Autohaus in Ewing, New Jersey, and is priced at $260,490, well above the $159,420 that Tesla sold it for earlier this year.

To those who do not know, the Model S Signature was a highly exclusive, limited-run farewell variant of the Model S Plaid that was produced this year to mark the end of production of both the Model S and Model X, Tesla’s two flagship vehicles.

Limited to just 250 units with invite-only sales, it serves as a collector’s item celebrating the legacy of the Model S, which helped pioneer Tesla’s electric vehicle success since its 2012 launch.

It bundles top-tier performance with bespoke cosmetic and luxury upgrades, plus Tesla’s Luxe Package. Here’s what the Model S Signature has over the typical Model S Plaid:

  • Exclusive Exterior – Unique Garnet Red Paint, matching door handles, gold Tesla “T” badges upfront, gold Plaid and Signature badging at the rear.
  • Premium Interior – White Alcantara upholstery with gold piping/accents, gold Plaid seat badges, Signature-marked door sills, individually numbered dashboard plaque, gold puddle lights, special interior lighting sequence, and a custom Signature key fob.
  • Performance Upgrades – Carbon-ceramic brakes with gold calipers
  • Bundled Luxe Package – Full Self-Driving (Supervised), four years of Premium Connectivity, free lifetime Supercharging
  • Performance Metrics – ~1,020 horsepower, sub-2-second 0-60 MPH, ~390-mile range

Tesla quickly introduced a No Resale Agreement for the Signature Editions of the Model S and Model X, which would penalize the seller for “the amount of $50,000 or the value received as consideration for the sale or transfer, whichever is greater.”

The company continues:

“If you sell or otherwise transfer the ownership of your Model S or Model X, the remainder of the Recommended Maintenance, Wheel and Tire Protection Plan, and Windshield Protection Plan will transfer automatically to the buyer. The Full Self-Driving (Supervised), Free Supercharging and Premium Connectivity will not transfer with the vehicle and will terminate once the ownership of the Model S or Model X is transferred.”

Tesla will likely come after the seller, especially as it has been about two months since Tesla launched deliveries.

Tesla Full Self-Driving v14.3.5 Early Impressions: new features and early performance

Published

Tesla rolled out Full Self-Driving (Supervised) v14.3.5 yesterday, and about fifty miles of driving on the new version has given me enough time to highlight what seems to be strong about the release and what is not.

Additionally, Tesla has added a few new features with this specific update, which we’ll highlight as well.

Tesla Full Self-Driving v14.3.5 Performance

The new update is business as usual. Things seem to be running completely normal and necessary, but there are a few things that we’ve seemed to pick up on based on our own experience with v14.3.5, as well as what other users are seeing.

Initially, it seems to be more aware of its surroundings, making moves that are incredibly courteous to other drives and operating just a tad more reserved than what the suite might have done previously.

We had two instances where it showed this, the first being FSD needing to pass a Flagger Force vehicle that was placing down signage for the day. Their work truck was right at the front corner of a right-hand turn; typically where most cars travel when they take that turn.

FSD v14.3.5 recognized this, slowed down, and took the turn wide with no issues:

Additionally, v14.3.5 backed up for a semi truck that was making a wide turn onto a road my car was on. This is not new, but it seemed to be backing up for courtesy; it didn’t seem completely necessary, but it might have put some peace of mind in the truck driver’s head:

X user Mike P, also a Pennsylvania native like myself, shared three clips of his Tesla running v14.3.5 performing similar maneuvers. He said:

“FSD turns right into a small alley that only fits one car at a time, sees oncoming car, reverses out of alley to make space, realizes oncoming car is actually parking, re-enters alley.”

Check it out here:

It seems like Speed Profiles are still in need of some tweaking; I am adjusting what Speed Profile I’m in frequently, constantly changing it to get it to travel at the correct speed. This was an issue for me on v14.3.4. It seems like they’re just a little inconsistent.

Terrible Parking

Parking attempts on v14.3.5 were not good. There are quite a few people who have said this:

David Moss, the Tesla owner who has taken multiple coast-to-coast drives without any interventions, also has had some issues with parking early on with v14.3.5:

New Features

Tesla has added the ability to open Camera Preview at any time. Previously, it was only available in Park. Here’s what that feature looks like in action:

Check back later this week for a longer review of what we’ve noticed on Full Self-Driving v14.3.5.
