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.

Elon Musk recently shared a Tesla Optimus dance video, showcasing the humanoid robot’s light feet and the company’s quick progress.

In 2021, Tesla announced it would develop a humanoid robot during AI Day. At the time, the company didn’t even have a prototype. To celebrate the announcement, a human dressed as a humanoid robot came out and danced for the crowd at the event. Fast forward a few years, and Tesla’s Optimus bot finally has some moves to show off.

The first time anyone got a real preview of Optimus was in 2022, when Tesla debuted semi-functional prototypes at AI Day. One Tesla Optimus bot walked on stage while another performed some arm movements. At the time, critics noted the Tesla Optimus bot’s reliance on teleoperation for some tasks.

By 2023, Tesla unveiled Optiumus Gen 2, demonstrating advanced tasks like sorting colored blocks, maintaining yoga poses, and some dancing. Tesla also noted that the robot’s hands improved to 11 degrees of freedom (DoF). Tesla Optimus hands in production units have 22 degrees of freedom.

Late last year, Tesla Optimus robots attended the company’s “We, Robot” event, performing tasks like serving drinks and interacting with people in the crowds. Teslarati played rock, paper, scissors with Optimus at “We, Robot.” The Tesla bots danced in synchronicity at the event with their arms and torsos.

Tesla’s progress with Optimus has been quite a ride over the past few years. Now Optimus can add to its dance moves with more flexibility and control over its legs. The recent Tesla Optimus dance video marks the beginning of the next phase for the humanoid robot: production.

According to Tesla’s Q1 2025 updated letter, the company has already started limited production of the Optimus bot at Tesla’s Fremont Factory. Elon Musk announced plans to produce over 1,000 units of Tesla Optimus for internal use in 2025 and external sales by 2026.

Elon Musk claims Tesla Optimus could be “more significant than Tesla’s vehicle business,” with a potential market value of $25 trillion. By automating low-skill, repetitive jobs, the Tesla bot could reshape economies, which Musk believes could lead to an “age of abundance” where goods and services are cheaper.

Rivian stock is gaining traction as Wall Street analysts raise price targets following the electric vehicle (EV) maker’s first-quarter earnings report. Despite a dip after the announcement, optimism surrounds Rivian’s cost control and upcoming lower-priced cars.

Last week, Rivian reported a better-than-expected Q1 gross profit, surpassing Wall Street’s forecasts with adjusted losses of $0.48 per share against expectations of $0.92 per share. The company also reported a revenue of $1.24 billion compared to the $1.01 billion anticipated.

However, the EV automaker cut its 2025 delivery forecast and capital spending due to President Donald Trump’s tariffs. It explained that it is “not immune to the impacts of the global trade and economic environment.” RIVN stock dropped nearly 6% post-earnings, closing at $12.72 per share.

Wall Street remains upbeat about Rivian, citing progress toward launching lower-priced vehicles in 2026 and effective cost management. On Monday, Stifel analyst Stephen Gengaro raised his RIVN price target to $18 from $16, maintaining a “Buy” rating. He highlighted Rivian’s “solid progress” toward key milestones.

Conversely, Bernstein’s Daniel Roeska gave RIVN a “Sell” rating. However, Roeska also lifted his Rivian price target to $7.05 from $6.10, acknowledging “better” Q1 results. He warned that profitability remains distant and hinges on multiple product launches by the decade’s end.

Overall, Wall Street’s average price target for RIVN climbed from $14.18 to $14.31, a modest 13-cent increase reflecting positive sentiment. About one-third of analysts covering Rivian rate it a Buy, compared to the S&P 500’s average Buy-rating ratio of 55%.

On Monday, Rivian stock rose 2.7% to $14.64, slightly trailing the S&P 500 and Dow Jones Industrial Average, which gained 3.3% and 2.8%, respectively. The uptick may also stem from broader market gains tied to news of a temporary U.S.-China tariff suspension.

As Rivian navigates trade challenges and scales production at its Illinois factory, its Q1 performance and analyst support signal resilience. With lower-priced EVs on the horizon, Rivian’s strategic moves could bolster its position in the competitive EV market, offering investors cautious optimism for long-term growth.

EU antitrust regulators are scrutinizing SES’s $3.1 billion bid to acquire Intelsat, probing whether SpaceX’s Starlink poses a credible rival in the satellite communications market. The European Commission’s review could shape the future of Europe’s space industry.

The Commission has sought feedback from customers of SES and Intelsat to assess Starlink’s competitive impact. According to Reuters, the questionnaire asks if low-earth orbit (LEO) satellite providers like Starlink and Eutelsat’s OneWeb are viable competitors for two-way satellite capacity. It also explores whether LEO suppliers are winning tenders and contracts and their potential to influence competition over the next five years. Additionally, regulators are evaluating customers’ bargaining power and ability to switch to rival suppliers.

SES operates a fleet of about 70 multi-orbit satellites for video broadcasting, government communications, and broadband internet. It aims to scale up through the acquisition of Intelsat. The move is part of a broader push in Europe to bolster home-grown satellite solutions, countering U.S. giants like SpaceX’s Starlink and Amazon’s Project Kuiper.

SES is in talks with the EU Commission and a few European governments to complement Starlink services, addressing concerns over reliance on foreign providers.

“Now the discussions are much more strategic in nature. They’re much more mid-term, long-term. And what we’re seeing is that all of the European governments are serious about increasing their defense spending. There are alternatives, not to completely replace Starlink, that’s not possible, but to augment and complement Starlink,” said SES CEO Adel Al-Saleh.

The EU Commission’s preliminary review of the SES-Intelsat deal is expected to conclude by June 10. The preliminary review will determine whether the SES-Intelsat deal is cleared outright, requires concessions, or faces a full-scale investigation if significant concerns arise. As Europe seeks to strengthen its space-based communication resilience, the outcome could redefine competitive dynamics in the satellite sector.

With Starlink’s LEO technology disrupting traditional satellite services, the Commission’s findings will signal how Europe balances innovation with strategic autonomy. SES’s efforts to scale and collaborate with governments underscore the region’s ambition to remain competitive, potentially reshaping the global satellite landscape as demand for reliable connectivity grows.
