MARBURG OUTBREAK IN RWANDA RAISES INTERNATIONAL HEALTH CONCERNS
A significant outbreak of Marburg virus in Rwanda has raised international alarms, with 27 cases reported, making it one of the largest on record. Tragically, nine individuals have died, and over 70% of the cases involve health professionals in two hospitals in Kigali, a major travel hub. The World Health Organization (WHO) has classified the risk of spread to neighboring countries as high and is investigating transmission chains, including a potential case linked to Belgium. Historically, Marburg outbreaks have been small, with only two exceeding 100 cases, but Rwanda’s advanced healthcare system is deemed capable of managing the situation effectively. The Rwandan government is conducting contact tracing for 300 monitored individuals. While there are experimental vaccines and treatments for Marburg, none are licensed, and Rwanda would need to permit their testing. The ongoing outbreak comes amidst regional mpox outbreaks, which could complicate control efforts if Marburg spreads. (STAT)
FLOREY BIOSCIENCES AIMS TO PROTECT GUT MICROBIOME HEALTH
Antibiotics, while effective against bacterial infections, can severely disrupt healthy gut microbes, posing risks for various diseases. With about 236 million prescriptions in the U.S. in 2022, this issue remains largely unmet. Florey Biosciences, co-founded by microbiologist Dr. Andrés Cubillos-Ruiz, aims to address this problem with its lead program, FLR-101—a genetically modified yeast that produces an enzyme to break down beta-lactam antibiotics, which account for about 50% of all antibiotics used. The yeast acts locally in the gut, protecting beneficial microbes while allowing antibiotics to combat infections elsewhere. Florey plans to market FLR-101 as a medical food, which doesn’t require the same regulatory hurdles as drugs. To differentiate it from other probiotics, Florey intends to conduct human trials to demonstrate FLR-101’s effectiveness in reducing microbiome damage when paired with antibiotics. The company is preparing for in vivo safety studies and aims to launch FLR-101 within three years, potentially transforming antibiotic stewardship and gut health management. (Fierce Biotech)
H5N1 AVIAN INFLUENZA RAISES CONCERNS FOR DAIRY FARMING
A recent experiment conducted in a high-security U.S. laboratory has raised alarms about the potential spread of the highly pathogenic H5N1 avian influenza, which is currently affecting dairy cows and calves across 231 farms in 14 states. Researchers found that the H5N1 virus accumulates in the udders and milk of infected cows, suggesting it may be transmitted through industrial milking systems. This poses a serious risk, as the variant spreading in Europe could also infect cattle, leading to similar outbreaks. The study, published in *Nature*, indicated that while cows infected through the respiratory route showed minimal symptoms, those infected via the udder suffered severe illness and significant drops in milk production. With H5N1 already infecting 59 mammal species, including humans, experts emphasize the need for mandatory testing, quarantines, and reinforced hygiene measures on farms to prevent further spread. The current outbreak underscores the urgency for robust surveillance and control measures to avert a potential epidemic. (El Pais)
PUBLIC RECORDS SYSTEMS FACING VULNERABILITIES ENDANGER VOTER INTEGRITY
Public records systems essential for managing voter registrations and legal filings are plagued by critical vulnerabilities, enabling potential attacks that could alter official documents. Security researcher Jason Parker discovered numerous flaws in 19 platforms used by various government entities. One significant vulnerability in Georgia’s voter registration cancellation portal allowed unauthorized individuals to cancel any voter’s registration with basic personal details. Additional weaknesses in document management systems compromised access to sealed psychiatric evaluations. Parker emphasized the need for robust permission controls, better user input validation, and regular security audits to prevent unauthorized access. He called for a comprehensive overhaul of security practices, including universal multifactor authentication. These vulnerabilities expose the failures in cybersecurity measures meant to uphold the integrity of systems that millions rely on, posing serious risks to both institutions and individuals’ privacy. Parker’s work highlights the urgent need for immediate action from vendors and agencies managing sensitive public data. (Ars Technica)
UNDERWATER ROBOTS LOCATE WRECK OF GHOST SHIP STEWART
On August 1, three advanced underwater robots were deployed northwest of San Francisco, where they successfully located the wreck of the “Ghost Ship of the Pacific,” also known as the U.S.S. Stewart (DD-224). This U.S. Navy destroyer, captured by Japanese forces during World War II, now lies in the Cordell Bank National Marine Sanctuary, nearly 3,500 feet underwater. The wreck is exceptionally well-preserved, making it one of the best examples of its kind. The discovery showcases the effectiveness of modern robotic ocean exploration, with Ocean Infinity operating the drones. This technology aids marine archaeology and has previously contributed to significant finds, such as the U.S.S. Nevada and the Endurance. The search for DD-224 had been ongoing for years, driven by the ship’s unique history, including its repurposing by the Japanese and its eventual sinking after target practice by the U.S. Navy. The find not only concludes an eight-decade mystery but also highlights the deep human connection people have with ships, representing more than just metal and machinery. (New York Times)
WHITE DWARF STAR IN NOVA EXPLOSION RIVALS NORTH STAR
Astronomers and stargazers are eagerly awaiting a spectacular event in the Corona Borealis constellation, 3,000 light-years from Earth. A white dwarf star, T Coronae Borealis (T Cor Bor), is set to reignite in a nova explosion that could briefly rival the brightness of Polaris, the North Star. This long-dead star last flared up almost 80 years ago, making this anticipated event a rare opportunity for observation. T Cor Bor, which is currently accumulating material from a nearby red giant star, has shown a noticeable dip in brightness, suggesting an imminent explosion. Astronomers plan to utilize multiple ground- and space-based telescopes, including NASA’s Fermi gamma-ray space telescope and the James Webb Space Telescope, to study the nova’s eruption and subsequent dynamics in unprecedented detail. The event will be visible to the naked eye for the first few days, providing a unique chance to explore the mechanics of nova explosions and their interactions with companion stars, all while posing no threat to Earth.
