TO THE MOON!
The U.S. has launched a spacecraft, Astrobotic’s Peregrine lander, from Cape Canaveral, Florida, aiming for a controlled landing on the Moon. This mission, the first American attempt at a soft touch-down in 51 years and a first for a private company, was propelled by the new Vulcan rocket. Peregrine carries five scientific instruments to study the lunar surface in preparation for future human missions. The landing, scheduled for 23 February, will target the Sinus Viscositatis, a smooth lunar plain. The mission marks a significant shift in space exploration, with NASA using commercial partners like Astrobotic, Intuitive Machines, and Firefly to lower costs. These companies, not NASA, are leading their missions. Peregrine’s payload includes a spectrometer to study lunar water, important for future astronaut missions. Besides scientific instruments, it carries cultural items and, controversially, cremated human remains, including those of author Arthur C. Clarke, sparking criticism from the Navajo Nation. 2024 will see several lunar missions, including those from Japan and China. Japan’s Jaxa aims for a January landing near Shioli crater, while China plans to collect far-side lunar rocks. The success of Vulcan’s maiden flight, developed by United Launch Alliance, highlights the growing role of private companies in space exploration. (BBC)
PSYCHEDELIC WONDER.
A trial in military veterans has shown promising results for treating traumatic brain injury (TBI) with ibogaine, a psychedelic drug. After treatment, participants reported an over 80% reduction in symptoms like PTSD and depression. This study, which lacked a control group, is published in Nature Medicine. Ibogaine is derived from a Central African shrub and has traditionally been used for opioid dependence. Its potential for treating TBI is significant, given the limited efficacy of current PTSD therapies. The 30 veterans in the study, having faced repeated exposure to combat or explosions, received ibogaine treatment in Mexico. Remarkably, they experienced substantial decreases in PTSD, depression, and anxiety symptoms, transitioning from moderate disability to no disability after a month. Cardiac side effects, a known risk of ibogaine, were not observed. This opens possibilities for further research into ibogaine’s long-term effectiveness and mechanism, potentially involving the re-opening of a developmental ‘critical period’ in the nervous system.

HEALTHCARE SYSTEM HEALTH CHECKS.
The People’s Voice Survey, conducted across 15 diverse countries, revealed that less than half of the population feels confident in accessing and affording quality healthcare when severely ill. Only 25% of respondents believe their health systems are adequate without needing major reforms. Confidence was notably low in Peru, the UK, and Greece, reflecting significant health system challenges. The survey also highlighted demographic trends, with wealthier, more educated, younger, and female participants showing less endorsement of their health systems, indicating potential future issues in maintaining support for publicly financed health systems. Key factors influencing public confidence included the perceived quality of public health services and the government’s responsiveness to public input. These findings, serving as a post-COVID-19 pandemic baseline, underscore the importance of regular monitoring to guide policy decisions and enhance health system accountability. This study emphasizes that population confidence is crucial for a well-functioning health system. (The Lancet Global Health)
SECRETS OF INHERITED HEART DISEASE.
Olalla Radío and her brother Esteban both carry the gene for hypertrophic cardiomyopathy, a hereditary heart condition. While Olalla’s condition is asymptomatic, Esteban suffers from a severe form, discovered when he was 15. Research by the Bellvitge Biomedical Research Institute and A Coruña Hospital in Spain using heart models created from the siblings’ stem cells revealed that an additional genetic variation causes Esteban’s more severe symptoms. Hypertrophic cardiomyopathy, affecting one in 500 people, varies greatly in manifestation and can lead to serious complications like arrhythmias. Esteban, now 41, experienced worsening symptoms over time and required an implantable cardioverter defibrillator. Olalla, at 43, remains symptom-free and took preventive measures for her children. The study, involving gene-editing techniques like CRISPR, provided insights into the disease’s variability and potential therapeutic targets. It highlights the importance of individual genetic factors in the disease’s severity and prognosis, opening avenues for personalized treatment approaches. (El Pais)
CLIMATE CHANGE AND AMR.
In 2021, microbiologist Adwoa Padiki Nartey in Ghana suffered from a bacterial infection resistant to antibiotics, illustrating the intersection of climate change and antibiotic resistance. Increased rainfall in Ghana, linked to climate change, promotes growth and spread of antibiotic-resistant bacteria. Globally, drug-resistant infections have risen by 15% since 2017. Misuse and overuse of antibiotics contribute to this trend, as bacteria evolve resistance. Studies show that higher temperatures, a consequence of climate change, correlate with increased antibiotic resistance. This suggests that climate change may exacerbate the antibiotic resistance crisis. Efforts to tackle antibiotic resistance include improving sanitation and educating on proper antibiotic use. Surveillance, integrating climate and health data, can predict outbreaks. Global collaboration, mirroring climate change initiatives, is crucial. This approach includes promoting clean water access and appropriate antibiotic use, essential steps in combating this growing health challenge. (Nature)
REIMAGINING THE MODERN LIBRARY.
De Krook in Ghent, Belgium, exemplifies the modern library, blending traditional book lending with community spaces for learning, connection, and development. Similar to Helsinki’s Oodi, Dokk1 in Aarhus, and Deichman Bjørvika in Oslo, De Krook is envisioned as a 21st-century city living room. This library welcomes a diverse range of visitors, from students to pensioners, and offers various facilities including a children’s library, workspaces, a café, and a makers’ room with modern equipment. Since its 2017 opening, De Krook has become a cultural hub, hosting lectures, concerts, and community-driven technological projects. Its popularity is evident in the rising library book loans, showcasing the enduring value of traditional library services amidst modern innovations. The library’s design fosters a city-within-a-city atmosphere, with vast windows and wide staircases, emphasizing openness and accessibility. De Krook’s success reflects a broader trend in Europe, where new-era libraries like Dokk1 and Oodi also combine functional design with cultural and social roles, redefining the library as a dynamic, inclusive community space.

SNAKE TEETH INDICATE BITE SPEED.
William Ryerson, a herpetologist at Cornell University, has conducted a detailed analysis of snake teeth and their striking behaviors, presenting his findings at the Society for Integrative and Comparative Biology’s annual meeting. His research involved examining the shape, position, and size of teeth in various snake species and filming their strikes using high-speed video. Ryerson discovered that these factors can predict a snake’s strike speed and direction. Previously, herpetologists focused mainly on fangs, but Ryerson’s work revealed significant diversity in other teeth. For instance, boa constrictors have long, upright teeth, while king snakes possess shorter, curved ones. His analysis of 70 snakes across 13 species showed that their attack patterns and dental structures fell into two categories: “strikers” like boa constrictors, which attack from above with lightning speed, and “lungers” like king snakes, which attack head-on more slowly. This study highlights the link between dental structure and predatory behavior in snakes. Ryerson’s insights could have practical applications in engineering, suggesting that the design of tools for piercing or gripping could be informed by these natural mechanisms. (Science)
