schwit1 shares a report from the Korea Herald: Korean Air, South Korea's flagship carrier, on Tuesday announced a sweeping $50 billion deal to purchase next-generation aircraft from Boeing and spare engines from GE Aerospace and CFM International, its largest-ever investment aimed at fueling long-term growth. The deal, signed during President Lee Jae Myung's visit to Washington, includes $36.2 billion for 103 Boeing aircraft, $690 million for 19 spare engines, and a $13 billion long-term engine maintenance contract. The fleet order spans a wide mix of models: 20 Boeing 777-9s, 25 Boeing 787-10s, 50 Boeing 737-10s, and eight Boeing 777-8F freighters. Deliveries will be phased through the end of the 2030s. Korean Air will also acquire 11 spare engines from GE Aerospace and eight from CFM International, alongside a 20-year maintenance service agreement with GE covering 28 aircraft.

alternative_right shares a report from Phys.org: You've probably heard it before in a meeting: 'Let's touch base offline to align our bandwidth on this workflow.' Corporate jargon like this is easy to laugh at -- but its negative impact in the office can be serious. According to a new study, using too much jargon in the workplace can hurt employees' ability to process messages, leading them to experience negative feelings and making them feel less confident. In turn, they're less likely to reach out and ask for or share information with their colleagues. "You need people to be willing to collaborate, share ideas and look for more information if they don't understand something at work," said Olivia Bullock, Ph.D., an assistant professor of advertising at the University of Florida and co-author of the new study. "And jargon might actually be impeding that information flow across teams." Age made a difference, though. Older workers had a harder time processing jargon, but were more likely to intend to ask for more information to clarify the message. Younger employees were less likely to seek and share information when confused by jargon. "It gives credence to the idea that younger people are more vulnerable to these workplace dynamics," Bullock said. "If you're onboarding younger employees, explain everything clearly." The findings have been published in the International Journal of Business Communication.

An anonymous reader quotes a report from ScienceAlert: A genetically modified pig lung transplanted into a brain-dead human patient functioned for nine days in a new achievement that reveals both the promise and significant challenges of xenotransplantation. Over the course of the experiment, the patient showed increasing signs of organ rejection before scientists at the First Affiliated Hospital of Guangzhou Medical University in China terminated the experiment, allowing the recipient to pass away. It's the first time a pig lung has been transplanted into a human patient, demonstrating a significant step forward, and giving scientists new problems to solve as they develop this emerging medical technique further. [...] The goal of the experiment was not to achieve a successful transplantation on the first try -- that would have been pretty incredible, but not a realistic expectation. Rather, the researchers wanted to observe how the patient's immune system responded to the transplanted organ. The patient was a 39-year-old man who was declared brain-dead by four separate clinical assessments after undergoing a brain hemorrhage. His family provided written informed consent for the experiment. The donor pig is what is known as a six-gene-edited pig, a Bama miniature pig with six CRISPR gene edits, housed in an isolated facility with rigorous disinfection protocols. These edits are all focused on minimizing the immune and inflammatory responses of the patient. In a careful surgical procedure, the pig's left lung was placed into the patient's chest cavity, and connected to their airways, arteries, and veins. The paper does not explain the fate of the pig, but donor pigs do not typically survive the removal of a major organ. The patient was also treated with a number of immunosuppressants that the researchers adjusted according to changes observed in the patient's body over time. Initially, all seemed well, with none of the immediate signs of hyperacute rejection in the critical few hours following the procedure. However, by 24 hours after the transplant had taken place, severe swelling (edema) was observed, possibly as a result of blood flow being restored to the area of the transplant. Antibody-mediated rejection damaged the tissue further on days three and six of the experiment. The result of the damage was primary graft dysfunction, a type of severe lung injury occurring within 72 hours of a transplant, and the leading cause of death in lung transplant patients. Some recovery was taking place by day nine, but the experiment had run its course. The research has been published in Nature Medicine.
