SpaceX's Starship Explodes on Test Stand in Yet Another Setback
The huge blast enveloped the craft as it stood upright at Starbase, before massive plumes of flames and smoke mushroomed into the night sky, according to video footage of the incident late Wednesday.

Claims Data Fail to Accurately Identify MI Types
TOPLINE: Clinical auditing reveals significant misclassification in administrative codes for myocardial infarction (MI), with only 39% of type 1 (T1MI) codes and 72% of type 2 (T2MI) codes for the condition accurately reflecting the true diagnosis, researchers found. Nearly half of patients coded for T1MI had T2MI, whereas 26% of T2MI codes represented myocardial injury. METHODOLOGY: Researchers identified 350 randomly sampled patients with T1MI codes and 350 patients with T2MI codes during inpatient encounters using the International Statistical Classification of Diseases and Related Health Problems-10th Revision. The analysis included patients aged 65 years and older from October 1, 2017, to May 9, 2024, within eight hospitals in the Mass General Brigham system. Using the 4th Universal Definition of MI, the researchers reviewed the clinical encounters to assess evidence of plaque erosion or thrombus vs oxygen demand-supply imbalance. A second physician review was conducted for 146 challenging and 146 nonchallenging cases. TAKEAWAY: Among the 350 patients coded as having had T1MI, clinical adjudication revealed 138 (39%) as correctly diagnosed; 159 (45%) in fact had T2MI, and 35 (10%) had myocardial injury. Of the 350 patients coded as having had T2MI, 251 (72%) were confirmed, four (1%) were found to have T1MI, and 91 (26%) had myocardial injury. A second physician review demonstrated a high degree of agreement with the initial review, with a 94% agreement in nonchallenging cases and 86% in challenging cases. Hospitals equipped with vs without cardiac catheterization laboratories showed significantly lower misclassification rates (43% vs 58%; P = .0298). IN PRACTICE: 'Among individuals assigned a T1MI claims code, nearly one half have T2MI and many others have myocardial injury; fewer than one half have true T1MI,' the researchers reported. 'Our results also confirm and extend previous work showing that among those with T2MI codes, slightly more than one half have true T2MI, with most of the misclassification related to myocardial injury rather than T1MI. This has critically important implications for epidemiology and public policy' related to acute myocardial infarction. SOURCE: The study was led by Andrea Martinez, MD, of the Department of Medicine at Massachusetts General Hospital, Boston. It was published online on July 21 in Journal of the American College of Cardiology. LIMITATIONS: The results may not be generalized to other hospital systems and countries, where patterns of misclassification might differ. The researchers noted external validity assessment across multiple healthcare systems and in countries that have already introduced International Classification of Diseases-11th revision coding would be beneficial. While patterns of misclassification might have changed over time, the analysis was intentionally restricted to the period when codes for both T1MI and T2MI were available. DISCLOSURES: The study received support through a grant to Jason Wasfy from the Massachusetts General Hospital Executive Committee on Research. Individual authors reported receiving other grants and support, including grants from industry. This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

Remember Ingenuity? NASA's proposed Skyfall mission takes it further in stunning video
NASA's incredible Ingenuity helicopter spent nearly three flying across the surface of Mars, becoming the first aircraft to achieve powered, controlled flight on a planet other than Earth. After suffering damage to one of its blades in early 2024, Ingenuity was grounded for good, and now rests on the martian surface as a testament to technological innovation and the triumph of autonomous flight on another planet. In an exciting development, the plucky helicopter has now inspired Skyfall, a mission concept recently unveiled by Virginia-based AeroVironment (AV) and NASA's Jet Propulsion Laboratory (JPL), who worked together to develop the Ingenuity aircraft. As you can see in the video at the top of this page, the Skyfall mission is designed to deploy not one but six helicopters on Mars, each of which would fly off to explore various locations selected by NASA as potential landing spots for the first crewed mission to the red planet, which could take place in the 2030s. The gathered data could also help scientists learn more about Mars, contributing to the expanding database of information collected by other Mars vehicles such as the Perseverance and Curiosity rovers. The video shows the dramatic Skyfall Maneuver, described by AV as 'an innovative entry, descent, and landing technique whereby the six rotorcraft deploy from their entry capsule during its descent through the martian atmosphere.' With the helicopters flying down to the Mars surface under their own power, the Skyfall system would do away with the need for a landing platform, which is one of the most expensive parts of any Mars mission and also carries huge risk. Just like Ingenuity, each helicopter would be capable of operating autonomously, and beam high-resolution imagery back to Earth for analysis, allowing mission planners to select the best possible landing location for the first human mission. 'Skyfall offers a revolutionary new approach to Mars exploration that is faster and more affordable than anything that's come before it,' said William Pomerantz, head of space ventures at AV. 'Thanks to a true partnership between industry and government, we're expanding the unprecedented success of Ingenuity.' Pomerantz added that with six helicopters, 'Skyfall offers a low-cost solution that multiplies the range we would cover, the data we would collect, and the scientific research we would conduct, making humanity's first footprints on Mars meaningfully closer.' With NASA's first human missions in mind and the need to identify an ideal landing area, AV is already working with NASA's JPL in the hope of getting the green light for the mission before working toward a potential 2028 launch.
