Rare blood-clotting disorders linked to certain COVID-19 vaccines and corrections to a published study on pig-to-human kidney transplants were among the recent developments making headlines. Additionally, the increasing use of GLP-1 drugs for weight management and ongoing advancements in artificial intelligence continue to spark discussion.
Researchers uncovered the molecular trigger for a rare but potentially deadly clotting disorder, vaccine-induced immune thrombocytopenia and thrombosis (VITT), that some individuals experienced after receiving certain COVID-19 vaccines, according to a report published in The New England Journal of Medicine. The condition, linked to vaccines made by Johnson & Johnson in the United States and AstraZeneca in other countries, affected approximately one in 200,000 people who received the Johnson & Johnson vaccine and about three out of every 100,000 who received the AstraZeneca vaccine, according to Source 2. Many countries adjusted their vaccine recommendations as a result.
In other medical news, a correction was issued to a Nature article published on November 13, 2025, regarding a pig-to-human kidney xenotransplant. The corrections addressed errors in the figure labels, specifically the y-axis label in Fig. 1c, which should have read 1.73 m2 instead of 1.73 m2. The y-axis label in Fig. 1d should have read µl-1 instead of ml-1. The y-axis label in Fig. 2b should have read IgM instead of IgG. These corrections were made to both the HTML and PDF versions of the article, according to Source 1.
The use of GLP-1 drugs for weight management also continues to be a prominent topic, prompting ethical discussions, according to both NPR News and Nature News. These drugs are increasingly utilized, as reported by multiple sources.
Furthermore, the rapid advancements in artificial intelligence are drawing attention. One viral essay on X, "Something Big Is Happening," compared the current moment in AI to the early days of the COVID-19 pandemic, according to Source 3. The founder and CEO of OthersideAI, Matt Shumer, argued that AI has evolved from a useful assistant to a general cognitive substitute, with systems now capable of rivaling most human expertise. However, the article also noted that the tech is improving rapidly, but it won't remake the economy overnight.
Other developments highlighted by multiple sources include the ongoing use of Xenon gas in spacecraft propulsion, the role of nutrition in athletic performance, heightened brain activity during meditation, and security concerns regarding the AI tool OpenClaw. The re-installation of the "Barbed Wire Fence Telephone II" art project at CU Boulder was also mentioned.
