NO SAFETY CONCERNS.

A recent study suggests GLP-1 agonists, used for obesity and diabetes treatment, don’t increase suicidal thoughts, countering previous concerns. The study, analyzing over a million U.S. health records, found no link between these drugs (including Ozempic and Wegovy) and suicidal ideation, possibly indicating a protective effect. However, experts urge caution, noting the study’s limitations and the need for more research. Concerns about these drugs’ side effects, including gastrointestinal issues and rare complications like pancreatitis, persist. Investigations by European and U.S. drug regulators into potential suicidal side effects are ongoing. The study compared patient records on semaglutide (a GLP-1 drug) with other medications, showing lower reported rates of suicidal thoughts among semaglutide users. Nonetheless, factors like underreporting of suicidal thoughts and medication non-adherence could influence these results. Future research, including longer follow-ups and trials including people with depression, is essential for clearer understanding. (Science)

NAVAJO CONCERNS ABOUT LUNAR DESECRATION.

The upcoming launch of United Launch Alliance’s Vulcan Centaur rocket, carrying Astrobotic’s Peregrine lunar lander and memorial payloads by Elysium Space and Celestis, has sparked controversy. These payloads include human remains and DNA, with Celestis’ mission featuring cremains of “Star Trek” icons and others. However, the Navajo Nation President, Buu Nygren, has objected to this practice, citing the moon’s sacred status in many Indigenous cultures. He expressed disappointment in NASA and the U.S. Department of Transportation (USDOT) for not consulting with the Navajo Nation, as promised after a similar incident in the 1990s. Despite these objections, the mission is a private commercial launch under NASA’s Commercial Lunar Payload Services (CLPS) program, with no jurisdiction for NASA over additional payloads. NASA’s representatives acknowledged the controversy but stated that private companies in the CLPS program have autonomy over their payloads. Celestis CEO Charles Chafer defended the mission, stating that religious beliefs should not dictate space missions. The issue highlights the complex intersection of cultural beliefs, commercial space initiatives, and regulatory processes. (Space.com)

FUTURE OF POWERING SPACE STATIONS.

The Indian Space Research Organisation (ISRO) has successfully tested a 100W class Polymer Electrolyte Membrane Fuel Cell based Power System (FCPS) on the PSLV Orbital Experimental Module (POEM), launched on January 1. This fuel cell, an efficient electric generator, operates on electrochemical principles, producing electricity directly from hydrogen and oxygen gases, alongside pure water and heat. During the test, 180W of power was generated, providing valuable data on the performance of the system’s static and dynamic components and the underlying physics. This technology is particularly suitable for space missions involving humans, as it can simultaneously provide electric power, water, and heat from a single system. Furthermore, with water as its only byproduct, the fuel cell is emission-free, making it an ideal power source for space stations. Beyond space applications, these fuel cells have significant societal potential, such as in replacing vehicle engines for emission-free transportation and serving as standby power systems. Their ability to offer range and refueling times comparable to conventional engines gives them an advantage over batteries, positioning them as a promising solution for sustainable energy needs.
