BRAZIL GRAPPLES WITH DENGUE CRISIS, VACCINE SHORTAGE WOES.
Brazil faces a significant challenge with an unprecedented surge in dengue, exacerbated by hot rainy seasons and urbanization. The country’s vaccine supply is insufficient, with only 3.3 million people expected to be vaccinated this year out of a population exceeding 220 million. Efforts to develop a locally produced vaccine, promising cheaper and more effective protection, won’t be available until 2025. Meanwhile, innovative mosquito control strategies, such as releasing Wolbachia-infected mosquitoes and sterile male mosquitoes, show promise in reducing dengue transmission but require time to be implemented nationwide. Takeda’s Qdenga vaccine, offering protection against all four dengue serotypes, is in limited supply, and current vaccination efforts target only a fraction of the vulnerable population. The upcoming Butantan-DV vaccine, potentially offering broad and long-lasting protection, could change the landscape once approved. Despite the current challenges, experts remain hopeful that a combination of vaccination, mosquito control, and education will eventually mitigate the dengue crisis. (Science)
ENGLAND GRAPPLES WITH SURGE IN FOOD POISONING CASES.
England has seen a significant rise in food poisoning cases, with hospital admissions for salmonella infections reaching an all-time high of 1,468 between April 2022 and March 2023. E coli and campylobacter cases have also surged to record levels. Experts attribute the increase to various factors, including reduced regulatory focus, lower importation standards post-Brexit, and local authority budget cuts, though the UK Food Standards Authority credits improved detection methods. The situation is exacerbated by imported poultry products, particularly those linked to a recent salmonella outbreak traced back to Poland. This rise in foodborne illnesses highlights the need for stricter food safety governance and standards, both domestically and in imported goods. The Food Standards Agency and health professionals emphasize the importance of proper food handling and hygiene practices to mitigate the risk of food poisoning, suggesting that a majority of these cases are attributable to food sources.

FLORIDA HOUSE PASSES ANTI-TRANS BILL AMIDST CRITICISM.
The Florida House, led by Republicans, passed a controversial anti-trans bill that could significantly impact health insurance costs for all residents. This “trans erasure bill” not only aims to prevent trans individuals from having driver’s licenses with their true gender but also mandates private health insurance plans to cover “conversion therapy,” a widely discredited practice aimed at changing an individual’s sexual orientation or gender identity. Critics argue that this not only targets the trans community by making public life and healthcare more inaccessible but also damages the broader healthcare system by potentially increasing insurance costs for everyone. The bill forces health insurers to cover therapy that denies the validity of gender dysphoria, insisting on the alignment of gender identity with sex assigned at birth. This move has sparked concerns about the broader implications of such legislation, emphasizing the need for opposition to protect not just the rights of trans people but the integrity of healthcare for all Floridians.

ANTHROPOCENE EPOCH PROPOSAL REJECTED AMIDST CONTROVERSY.
The Anthropocene, a term denoting human-induced changes on Earth, was proposed to start in 1952, marked by radioactive fallout from hydrogen bomb tests. However, on March 4, 2024, the Subcommission on Quarternary Stratigraphy rejected this proposal, with 12 of 18 members voting against defining it as a new geologic epoch, highlighting a discrepancy with traditional epoch-defining standards. This decision does not dispute human impact on the planet but questions the narrow framing of the Anthropocene’s start date. Critics, including ecologist members of the Anthropocene Working Group, argue that tying the Anthropocene to such a specific and recent event could obscure the broader and deeper history of human influence on Earth. The original idea, proposed by Paul Crutzen in 2000, suggested the Anthropocene began with the Industrial Revolution in the late 18th century, acknowledging human impacts like climate change and biodiversity loss. Despite the rejection, the Anthropocene concept continues to stimulate research and discussion on human effects on the planet, serving as a call to address these transformative changes.

FIGURE RAISES $675M TO ADVANCE AI-POWERED ROBOTICS.
Autonomous bipedal robots have evolved significantly from their early, clumsy iterations to promising developments in human-robot collaboration. Leading this transition, Figure has raised $675 million from tech giants and partnered with OpenAI to enhance its robots with advanced AI, aiming to deploy them in manufacturing settings. This partnership seeks to improve robots’ semantic understanding and language processing, making them more adaptable and efficient in real-world tasks. Figure’s robot, designed for general-purpose tasks such as lifting and autonomous navigation, showcases the potential to mitigate labor shortages and automate repetitive or dangerous jobs. Advances in technology have improved these robots’ mobility and functionality, indicating a shift from theoretical research to practical engineering challenges. While significant progress has been made, the integration of AI models like OpenAI’s is expected to further refine these robots’ capabilities, particularly in understanding and executing complex tasks alongside human workers, highlighting a future where robots could enhance various industries by performing tasks that are currently challenging, unsafe, or unappealing for humans.

NASA DISCOVERY INSPIRES FOOD STARTUP’S SUSTAINABLE PROTEIN REVOLUTION.
In 2009, NASA researcher Mark Kozubal discovered a unique microbe in a Yellowstone hot spring, leading to the creation of Nature’s Fynd, a food company utilizing this microbe, Fusarium str. Yellowstonensis, to produce sustainable protein products. This discovery parallels the finding of Thermus aquaticus in 1966, which revolutionized PCR tests. Initially considered for biodiesel, the microbe’s potential for food production became evident, inspiring the launch of Nature’s Fynd in 2018. The company has developed a fermentation process to grow the microbe into a protein-rich mat, which can be transformed into various food items, including meatless burgers and dairy-free products. Nature’s Fynd products, rich in essential amino acids, have reached consumers nationwide, including Whole Foods. The startup is exploring broader applications, including space missions and nutritious feedstock for agriculture, demonstrating the microbe’s versatility and potential to address food sustainability and security challenges globally.
