KENNEDY PROPOSES SHIFT IN VACCINE TESTING REQUIREMENTS
Secretary of Health and Human Services, Robert F. Kennedy Jr., has proposed a shift in vaccine testing, requiring all new vaccines to undergo placebo-controlled trials before approval. While the move is intended to increase transparency, experts worry it could limit vaccine access, undermine public trust, and disrupt vaccine production. The proposal aims to test even well-established vaccines like measles, which some health professionals argue could be unethical, as it would deprive some participants of proven protection. Public health experts caution that the changes could slow vaccine development and availability, especially for critical vaccines like the coronavirus shot. Kennedy’s stance on vaccine safety has raised concerns, with some viewing his approach as promoting misinformation and misrepresentation of vaccine safety data. The proposal’s vague implementation details and potential ethical issues around placebo testing for established vaccines remain contentious, with experts warning that it could lead to greater public health risks.

NIH RESEARCH FACILITY SHUTDOWN HALTS VITAL DISEASE STUDIES
The Integrated Research Facility at the US National Institutes of Health (NIH) in Frederick, Maryland, which conducts vital research on deadly diseases like Ebola, Lassa fever, and SARS-Cov-2, has been instructed to cease its experimental work by the Department of Health and Human Services (HHS). The facility, part of the National Institute of Allergy and Infectious Diseases (NIAID), was told to stop all studies by April 29, including research on Eastern equine encephalitis (EEE). The shutdown, linked to personnel issues that allegedly compromised the facility’s safety culture, has led to the termination of critical research and placed the facility’s director, Connie Schmaljohn, on administrative leave. HHS confirmed the research pause, citing safety concerns but did not provide specifics on the personnel issues. This action is part of a broader restructuring effort within HHS, which includes significant job cuts across federal health agencies, raising concerns about the impact on public health research and safety.

WHO REPORT HIGHLIGHTS GLOBAL CONCERNS OVER ANTIBIOTIC OVERUSE
A new report from the World Health Organization (WHO) reveals global concerns about the overuse of antibiotics, which may contribute to antimicrobial resistance (AMR). Based on 2022 data from the Global Antimicrobial Resistance Use and Surveillance System (GLASS), the study highlights problematic areas in antibiotic use across 60 countries. The WHO’s AWaRe classification system shows that only 52% of the 16.6 billion daily doses of antibiotics were “Access” antibiotics, which are recommended for common infections. WHO aims for 70% of antibiotic use to come from this category by 2030, but only 31.7% of countries met the target. Alarmingly, 45.3% of antibiotics used were from the broader-spectrum “Watch” category, indicating potential misuse. The report also points to limited access to “Reserve” antibiotics in low-income countries. WHO advocates for stronger antibiotic stewardship to prioritize Access antibiotics and reduce inappropriate use, especially in countries with high AMR risks. (CIDRAP)
BIPARTISAN SENATORS OPPOSE TRUMP’S NIH BUDGET CUTS
A bipartisan group of U.S. senators has voiced strong opposition to President Trump’s proposed cuts to the National Institutes of Health (NIH) budget, which could reduce funding by up to 44%. The senators expressed concerns that such cuts would jeopardize the U.S.’s global leadership in biomedical research. Trump’s administration has already hindered NIH’s work by blocking funds, canceling grants, and reducing staff. The senators, including Susan Collins (R-ME) and Patty Murray (D-WA), warned that these actions threaten advancements in public health, economic benefits, and national security. Experts, including Sudip Parikh from AAAS, emphasized that slashing the NIH budget could hinder competition with China in biomedical research. Additionally, Trump’s plan to reduce funding for infrastructure and administrative costs for universities was criticized, with some Republicans proposing a cut to the indirect cost recovery rate from 40% to 15%, a move universities argue would devastate their research capabilities. A second hearing will be held to address these concerns. (Science)
MEASLES OUTBREAKS SPREAD ACROSS MULTIPLE STATES AMID LOW VACCINATION RATES
The Kansas Department of Health and Environment (KDHE) reported 9 more measles cases, bringing the total to 46 infections across eight southwestern counties, mostly affecting unvaccinated children. The outbreak is linked to a larger one in West Texas, with 42 patients either unvaccinated or with unknown vaccination status. One patient was hospitalized, but no deaths were reported. Montana also reported two new cases in Gallatin County, linked to out-of-state travel, raising its total to seven cases. None of the new patients were vaccinated. In Ohio, Defiance County confirmed one adult case with minimal contact, bringing Ohio’s total to 32 measles cases this year, most linked to local transmission. Ashtabula and Knox counties have seen the highest numbers in Ohio. Public health officials continue to monitor the situation, with concerns about the spread of the virus in areas with lower vaccination rates. (CIDRAP)
LONDON BANKS FINANCE MAJOR FOSSIL FUEL PROJECTS DESPITE CLIMATE GOALS
A study has revealed that nine banks in the City of London, including HSBC, NatWest, Barclays, and Lloyds, have financed companies responsible for at least 117 major fossil fuel projects, known as “carbon bombs,” between 2016 and 2023. These projects, spanning 28 countries, could produce 420 billion tonnes of carbon emissions, equivalent to over 10 years of global CO2 emissions. Despite the UK’s climate goals, these banks have poured more than $100 billion into these high-emission projects, undermining climate progress. HSBC has been the largest financier, supporting 104 of these projects. The study highlights the UK’s role as a major financial hub for destructive fossil fuel expansion, challenging its leadership in climate finance. Critics argue that UK banks must choose between continuing fossil fuel investments or supporting global efforts toward a sustainable, low-carbon future. Some banks, such as Barclays and NatWest, defended their broader climate financing efforts. (The Guardian)
PICURIS PUEBLO USES DNA RESEARCH TO VALIDATE ANCESTRAL HISTORY
For the first time, the Picuris Pueblo, a federally recognized Indigenous tribe in New Mexico, has used DNA research to validate their ancestral history. The tribe’s oral traditions link them to Chaco Canyon, a significant site of Pueblo culture, but their heritage has often been overlooked. In response to potential oil and gas drilling near Chaco Canyon, Picuris leaders, including Lt. Gov. Craig Quanchello, collaborated with geneticists to use DNA sequencing to strengthen their claims and protect their heritage. The study, published in Nature, revealed strong genetic ties between 13 current Picuris members and ancient ancestors from the 1300s-1500s who lived near Chaco Canyon. This research contrasts with past practices where archaeologists and geneticists studied Indigenous artifacts without consent. The study highlights the ongoing cultural and environmental concerns for the Pueblo people, particularly regarding drilling activities near the sacred site, which remains central to their identity and cultural preservation.

STUDY SHOWS FIBER-RICH DIET BEATS FECAL TRANSPLANTS FOR GUT RECOVERY
A study in mice, published in Nature, suggests that a diet rich in fiber and low in fat can help replenish gut microbiomes damaged by antibiotics, proving more effective than fecal transplants. The research found that a healthy diet promotes the recovery of gut microbial diversity, whereas an unhealthy diet prevents such recovery, rendering transplants ineffective. The study highlights the importance of diverse intestinal flora for digestion, immunity, and overall health, noting that a Western diet high in refined sugars leads to dysbiosis, where only a few microbial species dominate. Researchers found that mice fed a healthier diet saw microbial species return, even without a fecal transplant. While fecal transplants have shown some success for specific infections like Clostridium difficile, the study emphasizes that diet plays a critical role in long-term gut health. Future studies will explore fiber-rich supplements to restore gut health without a complete dietary overhaul. (Nature)
SEMAGLUTIDE SHOWS PROMISE IN TREATING LIVER DISEASE LINKED TO OBESITY
New research published in the New England Journal of Medicine suggests that semaglutide, the active compound in the weight-loss drug Wegovy, may be effective in treating metabolic dysfunction-associated steatohepatitis (MASH), a severe liver disease linked to obesity and Type 2 diabetes. The study, sponsored by Novo Nordisk, included 800 adults with moderate to advanced liver scarring. After 72 weeks, 63% of participants who received semaglutide showed improvements in liver fat and inflammation, compared to 34% in the placebo group. Additionally, 37% of the semaglutide group had less liver scarring, versus 22% in the placebo group. Semaglutide also contributed to significant weight loss, lower blood sugar, and improved insulin resistance, which likely helped reduce liver damage. Novo Nordisk has requested FDA approval for Wegovy to treat MASH, joining Eli Lilly, which is also researching treatments for the disease. However, the study’s limitations include a lack of racial diversity, as most participants were white. (New York Times)
NEW SOLAR IMAGE REVEALS UNPRECEDENTED DETAIL OF SUN’S SURFACE
A new image of the sun, captured by the US National Science Foundation’s Daniel K. Inouye Solar Telescope, provides unprecedented detail of its surface, shedding light on its fiery complexity. The image, taken with the telescope’s Visible Tunable Filter (VTF), reveals massive sunspots marking areas of intense magnetic activity, where solar flares and coronal mass ejections (CMEs) are likely to occur. These energetic outbursts can affect Earth’s infrastructure, including power grids and communication systems. The sun’s magnetic activity follows an 11-year cycle, and the current solar maximum is expected to last several months, making it an ideal time for the telescope’s advanced imaging capabilities. The VTF allows scientists to capture 3D views of the sun’s layers by tuning to different wavelengths of light. This technology, a decade in development, will help researchers study solar temperature, pressure, and magnetic fields, providing critical data to understand solar weather. (CNN)
