How euthanasia allowed an “à la carte” face transplant to be planned in 3D in Barcelona

Spain has once again shown why remains at the top in terms of organ transplants refers to the new milestone that has occurred at the Vall d’Hebron Hospital in Barcelona. It is neither more nor less than first face transplant in history coming from a donor who had requested the euthanasiadying in a controlled manner in a hospital environment. The programming. Until now, face transplants, of which a few have been performed 54 worldwidedepended on the urgency and availability of a donor who died due to an accident or brain death. However, this case introduces a new variable: transplant scheduling. This is thanks to the fact that the donor had requested to benefit from the Euthanasia Law and jointly expressed their willingness to donate all their organs and tissues, specifically their face. This is something that allowed the medical team timewhich is not common in transplants, to find the most suitable candidate and also plan in detail what the procedure was going to be like. What they did. By knowing in advance the availability of the donor, the medical team was able to begin virtual 3D planning. In this case, digital models of both the donor and the recipient were created to be able to design completely personalized cutting and grafting guides to guarantee the success of the intervention. And it is not at all easy to do this type of transplant, since the bone structure and soft tissues must fit together with millimeter precision, reducing the usual uncertainty of these operations. The surgical challenge. The operation was not easy, since It lasted 24 hours and required the coordination of a team of nearly 100 professionals.including plastic surgeons, microsurgeons, anesthetists, nursing and immunology experts. And it was not a simple aesthetic operation by putting the skin on top and that’s it, but rather a complete reconstruction was sought at all times that included muscles, nose, lips, blood vessels and of course nerves. All of this could not be done without microsurgical equipment that allowed arteries, veins or nerves less than a millimeter in diameter to be ‘connected’ in order to have sensitivity, movement or the ability to eat. The recipient. Her name is Carme, and her life changed radically in 2024 while she was on vacation in the Canary Islands when she suffered a bite that caused a serious infection. The bacteria caused sepsis and death of the facial necrosis, causing him to lose part of his face and severely affecting his jaw. In this case the consequences were devastating, since Carme could barely open her mouth and had serious difficulties breathing and feeding. Not to mention his social life, which had been drastically reduced, with the mental impact that this entailed. According to his own statements, the transplant was “the only solution” to try to regain a normal life. Legal context. All this is not a coincidence, since the Vall d’Hebron was already a pioneer in 2010 in performing the first complete facial transplant in the world. Of the six transplants that have been performed in the history of Spain, half have taken place in this center, demonstrating the great experience they have in this regard. The procedure is also framed within the Euthanasia Law that came into force in Spain in 2021, which contemplates the possibility of donating organs. The generosity of the donor, who explicitly offered her face during the authorization process for her assisted death, has opened a new door for regenerative and transplant medicine, demonstrating that advance planning can be key to success in the most extreme surgeries.

offer “sun a la carte”

Suppose you acquire the power to cancel the night in a specific place in the world. What would you use it for? It’s not a new idea. During World War II, Nazi scientists fantasized about launching mirrors into space. in order to “fry” enemy cities. Fortunately, they didn’t have the technology to do it. In the 1990s, Russia really tried with the Znamya projectwhose sole intention was to illuminate the dark cities of Siberia during the long winter. However, the experiment was short-lived: the first prototype disintegrated in the atmosphere and the second was never deployed. A new attempt. In the era of photovoltaic solar energy, the Californian company Reflect Orbital plans deploy a constellation of gigantic mirrors in orbit with a new purpose: to reflect sunlight towards large photovoltaic plants on Earth during twilight hours. In other words, offer “sun on demand” as a service to increase the production of renewable energy. The company, which has already raised $20 million, carried out successful tests with hot air balloons, and is ready to make the leap into space. Its director, Ben Nowack, sums it up like this: “We want to make it as easy as possible: you go to a website, tell us your GPS coordinates and we send you some sunlight after dark.” They have already applied to the FCC for a license to launch their first demonstration satellite in 2026, with an 18 x 18 meter mirror. In the long term, they propose deploying a fleet of 4,000 satellites with reflectors of up to 55 x 55 meters. “Catastrophic” for science. As energy companies know, solar panels stop producing electricity just when demand picks up. Reflecting sunlight from the sky can solve this intermittency, a seemingly laudable idea that doesn’t appeal to everyone. Astronomers, already fighting a tough battle against light pollution, have reacted vehemently. “The whole point of this project is to illuminate the sky and extend daylight, and obviously from an astronomical perspective, that’s pretty catastrophic,” explains Robert Masseyfrom the Royal Astronomical Society of the United Kingdom. Worse than Starlink? Unlike constellations like SpaceX’s Starlink, where satellite glow is an unwanted effect that the company tries to mitigate, in the case of Reflect Orbital, light pollution is the main product. The beams of light would be four times brighter than the full moon, and would not only affect the illuminated area, because atmospheric dispersion would extend the impact to hundreds of kilometers around, according to the astronomers themselves. This would not only ruin astronomical observations, but could have devastating effects on wildlife, disrupting the circadian rhythms of countless species, experts say. Too late? The Reflect Orbital project comes at the worst possible time for astronomy. The night skies have been under siege for some time. Artificial objects in orbit have already increased the brightness of the night sky by more than 10% above natural levels, exceeding the threshold at which a place is considered “light polluted”. Satellite megaconstellations led astronomers to come together and create a common front to save the dark skies. The fear is that, if projects like Reflect Orbital succeed, there will soon be no dark corners on our planet from which to observe the universe. Hence many of the most ambitious and powerful telescopes are being deployed in space.
