METEOROLOGISTS FACE UNPRECEDENTED HARASSMENT DURING WEATHER EVENTS
Meteorologists are facing unprecedented levels of harassment and threats, particularly during significant weather events like Hurricanes Helene and Milton. These storms have sparked conspiracy theories about government manipulation of the weather, leading to accusations and abuse directed at weather professionals. For instance, Katie Nickolaou, a meteorologist in Michigan, expressed her frustration over receiving death threats related to her forecasts. Experts, including Marshall Shepherd from the University of Georgia, note a marked increase in aggression and scrutiny towards meteorologists, exacerbated by a polarized political climate. In addition to meteorologists, emergency workers have also encountered harassment, including unfounded claims against the Federal Emergency Management Agency (FEMA). The spread of disinformation, particularly from conservative circles, has created an environment of distrust that undermines the credibility of weather experts and hampers relief efforts. This alarming trend threatens to drive professionals out of the field and erode public trust in critical weather warnings. (New York Times)
SOCIAL MEDIA USE LINKED TO ADOLESCENT MENTAL HEALTH ISSUES
Social media has become integral to the lives of adolescents, with around 95% of high school students using it, often leading to negative mental health outcomes, such as depression and suicide risk. This report utilizes 2023 Youth Risk Behavior Survey data to investigate the relationship between frequent social media use and experiences of bullying, feelings of sadness, and suicide risk among U.S. high school students. It reveals that 77% of students use social media frequently, with higher rates among females and certain sexual identities. Frequent users face increased bullying victimization and persistent feelings of hopelessness, highlighting a need for further research on the nuances of social media’s impact. The findings aim to inform public health strategies that promote safe digital environments and support adolescents’ mental health, emphasizing the importance of understanding social media’s risks and benefits to effectively address these pressing issues.

ROSILIN INSTITUTE LEADS GENE EDITING TO IMPROVE LIVESTOCK HEALTH
Bruce Whitelaw, director of the Roslin Institute in Scotland, reflects on the legacy of Dolly the sheep, the first mammal cloned from an adult cell, while highlighting the institute’s shift from animal cloning to cutting-edge gene editing using CRISPR technology. This approach aims to develop farm animals that are more resilient to diseases like porcine reproductive and respiratory syndrome (PRRS) and avian influenza, which significantly impact livestock and, by extension, human health. For instance, researchers at Roslin have created genetically modified chickens resistant to bird flu, a disease that has decimated poultry populations worldwide. Using CRISPR, they modified a gene related to viral infection, resulting in nine out of ten chickens showing no signs of illness when exposed to the virus. Additionally, they’ve developed PRRS-resistant pigs, crucial for mitigating the billions in losses due to the disease. With FDA approval anticipated soon, these advancements could significantly benefit the agricultural industry and help prevent economic hardship for farmers affected by livestock diseases. (El Pais)
RESEARCH REVEALS LIMITATIONS OF IMMUNITY AGAINST SARS-COV-2
Recent research highlights the limited durability of immunity against SARS-CoV-2, revealing that vaccinations and previous infections do not consistently foster long-lived plasma cells (LLPCs) in bone marrow, which are essential for sustained antibody production. A study published in *Nature Medicine* examined 19 individuals who had received multiple mRNA COVID-19 vaccine doses and found that while nearly all had LLPCs producing antibodies against other pathogens, only one-third had LLPCs generating antibodies against SARS-CoV-2. The study suggests that the virus’s spike proteins may be spaced too widely to effectively stimulate B cells, hindering LLPC development. This points to a potential strategy for enhancing COVID-19 vaccines by improving spike protein presentation, possibly through virus-like particles that could mimic more effective vaccines. While current vaccines face challenges in inducing long-lasting immunity, the findings open avenues for future research to improve vaccine efficacy against COVID-19. (Science)
NASA’S EUROPA CLIPPER MISSION TO SEARCH FOR SIGNS OF LIFE
NASA is set to launch its Europa Clipper mission on Monday, the first to investigate Jupiter’s moon Europa in over a decade. This $5.2 billion mission aims to determine if Europa, which has a subsurface ocean beneath its icy crust, possesses the ingredients necessary for life. The Europa Clipper is NASA’s largest interplanetary spacecraft, weighing 12,500 pounds and featuring solar panels that extend over 100 feet. It carries nine scientific instruments, including cameras, spectrometers, and radar, designed to study Europa’s surface and interior. The launch will occur atop a SpaceX Falcon Heavy rocket from NASA’s Kennedy Space Center at 12:06 p.m. Eastern time, with live coverage starting at 11 a.m. If necessary, backup launch dates are available. After a journey of 1.8 billion miles and five and a half years, the spacecraft will enter orbit around Jupiter in April 2030, conducting 49 flybys of Europa to search for signs of life-supporting conditions. Scientists are particularly interested in exploring the ocean’s depth, surface composition, and magnetic field, which may provide insights into the moon’s potential for hosting life. (New York Times)
SPACEX ACHIEVES MILESTONE WITH FIFTH STARSHIP TEST FLIGHT
SpaceX successfully launched its fifth Starship test flight from Boca Chica, Texas, marking a significant achievement by returning the Super Heavy first-stage booster to land using large metal arms for recovery. The rocket lifted off at 7:25 a.m. (12:25 GMT) and sent the second-stage Starship on a trajectory towards the Indian Ocean for a controlled splashdown after atmospheric reentry. The Super Heavy booster separated at an altitude of 74 km (46 miles) and attempted to land back at the launch site, where it was caught by robotic arms attached to the launch tower, a first for the company. SpaceX founder Elon Musk celebrated the successful landing, calling it a milestone in engineering history. The flight director manually determined the landing attempt’s feasibility, ensuring both the booster and launch tower were stable. SpaceX has invested years in preparing for this moment, aiming to recycle Starship boosters similarly to its Falcon 9 rockets, which have revolutionized space launches. This success paves the way for future missions, including NASA’s plans to use Starship for lunar landings and eventual Mars exploration. (Al-Jazeera)
JAMES WEBB TELESCOPE IMAGES LOWEST-MASS EXOPLANET AF LEPORIS B
The James Webb Space Telescope (JWST) has successfully imaged AF Leporis b, the lowest-mass exoplanet directly observed outside our solar system, and the closest to its parent star. This achievement was crucial, as the planet was about to disappear behind its star’s light for potentially a decade. AF Lep b, a young planet estimated to be only 23 million years old, has a mass about 3.2 times that of Jupiter. The team utilized JWST’s coronagraph to block out the star’s light, allowing for the observation of the planet’s “firefly glow.” The challenge was heightened because the planet is moving closer to its star, making it increasingly difficult to detect. The observations revealed that AF Lep b has an active atmosphere with strong convection currents and unexpectedly high levels of carbon monoxide, suggesting vigorous updrafts. This research highlights JWST’s capabilities and sets the stage for future discoveries of new exoplanets and their characteristics. (space.com)
