MEASLES CASES SURGE AMID DECLINING VACCINATION RATES AND MISINFORMATION
Measles was declared eradicated in the U.S. in 2000, but cases have surged due to declining vaccination rates, driven by misinformation and political divisions. As of March 2024, 222 cases and two deaths have been reported, marking the first measles fatalities in a decade. Experts like Dr. Peter Hotez warn that vaccine hesitancy, fueled by COVID-era skepticism, is undermining public health. Federal and state policies have weakened vaccine mandates, while misinformation spreads through social media. Government responses, particularly from Health Secretary Robert F. Kennedy Jr., have been inconsistent, emphasizing “informed consent” over strong vaccination advocacy. Experts fear a resurgence of other preventable diseases like pertussis and polio. Calls for proactive public health messaging, better tracking of vaccine exemptions, and countering disinformation remain urgent. Despite vaccines’ success in preventing millions of illnesses and deaths, declining immunization rates threaten a return of once-vanquished diseases, underscoring the need for depoliticized, science-based health policies.

WHITE HOUSE PANDEMIC RESPONSE OFFICE DISSOLVED AMID BIRD FLU OUTBREAK
The White House Office of Pandemic Preparedness and Response Policy (OPPR), created in 2022 to coordinate pandemic responses, has been largely dismantled under President Trump, with only one staffer remaining. This comes amid a worsening bird flu outbreak that has affected 166 million poultry, 989 dairy herds, and at least 70 people, with one fatality. The administration has shifted focus away from public health, with Agriculture Secretary Brooke Rollins emphasizing economic concerns over containment. Health Secretary Robert F. Kennedy Jr. even suggested letting the virus spread through poultry flocks to develop immunity, a proposal experts warn could increase human and animal risk. Previously, OPPR held regular interagency meetings to coordinate responses, but under Trump, no briefings have been held. Lawmakers, including Sen. Patty Murray, have expressed alarm over OPPR’s sidelining, warning that public health coordination is being undermined amid rising threats like bird flu and measles. (Ars Technica)
JYNNEOS VACCINE SHOWS LOWER EFFICACY IN PEOPLE WITH HIV
A study in *The Lancet Infectious Diseases* found that one dose of the Jynneos vaccine was 58% effective against mpox overall but had lower efficacy in people with HIV (35%) compared to those without HIV (84%). Researchers in Germany analyzed over 6,000 participants, primarily men who have sex with men and transgender individuals, tracking vaccine safety and effectiveness. Adverse reactions were rare, and vaccinated individuals experienced significantly milder symptoms and faster recovery times. No vaccinated participants were hospitalized, while 3% of unvaccinated individuals required hospitalization. Experts suggest that weakened T-cell function in people with HIV may reduce vaccine efficacy and recommend a full two-dose series, possibly with additional boosters for immunocompromised individuals. Researchers also stress the need for studies in low-income regions, particularly Central Africa, where mpox remains endemic. The findings highlight the importance of broad vaccination coverage to mitigate severe mpox outbreaks and refine global immunization strategies. (CIDRAP)
AMYLOID-CLEARING TREATMENT MAY DELAY ALZHEIMER’S SYMPTOMS
A groundbreaking study suggests that early amyloid-clearing treatment may delay Alzheimer’s symptoms in individuals genetically predisposed to develop the disease in their 40s or 50s. The research, led by Washington University in St. Louis, found that long-term amyloid removal reduced the risk of symptom onset by 50% in a subset of participants. However, the study’s continuation is threatened by funding delays under the Trump administration, as NIH reviews and grants have been stalled. Participants fear losing access to potentially life-extending treatment, including Leqembi, an FDA-approved drug now being tested further. NIH’s shifting priorities under nominee Jay Bhattacharya, who questions the focus on amyloid research, add uncertainty. Scientists stress that while other Alzheimer’s factors like inflammation and tau proteins are being studied, blocking amyloid buildup remains a crucial strategy. Without NIH support, critical research into whether early intervention can prevent Alzheimer’s symptoms may be lost, leaving families in limbo. (AP)
CERN FACES CONTROVERSY OVER $30 BILLION FUTURE COLLIDER PLAN
CERN is facing controversy over its plan to build the Future Circular Collider (FCC), a massive $30 billion particle accelerator set to replace the Large Hadron Collider (LHC) by 2070. The FCC would be the largest and most powerful collider ever built, aiming to explore new physics beyond the Standard Model, including dark matter. The two-stage plan involves first constructing a “Higgs factory” by 2045 before upgrading to a high-energy proton collider. However, critics argue that the project is too long-term, expensive, and lacks community consensus, with some favoring alternative designs like linear colliders. Funding remains uncertain, with Germany unwilling to increase contributions and China considering a rival collider. CERN’s leadership has been accused of pushing the FCC plan without sufficient debate. While supporters argue it will sustain Europe’s leadership in physics, opponents warn of locking future generations into an expensive commitment. A crucial decision on the FCC is expected by 2026.

DARK ENERGY MAY EVOLVE OVER TIME, CHALLENGING COSMOLOGY MODEL
Astronomers using the Dark Energy Spectroscopic Instrument (DESI) have found compelling evidence that dark energy—believed to drive the universe’s accelerating expansion—may not be constant but could evolve over time. This challenges the standard model of cosmology, suggesting the universe’s expansion might slow or even reverse into a “Big Crunch.” DESI’s findings, based on nearly 15 million galaxies, indicate cosmic acceleration began earlier and is currently weaker than predicted. However, a separate study from the Atacama Cosmology Telescope reinforces the standard model, adding to scientific uncertainty. The results have sparked excitement and debate, with cosmologists suggesting that dark energy might be dynamic rather than a fixed force. The discrepancy between theory and observation, while not yet at the five-sigma threshold for discovery, hints at a major shift in understanding. Future telescopes like Euclid, Vera C. Rubin Observatory, and NASA’s Roman Space Telescope aim to further unravel the universe’s mysteries. (New York Times)
JWST CAPTURES IMAGES OF GAS GIANT PLANETS IN HR 8799 SYSTEM
The James Webb Space Telescope (JWST) has captured direct images of gas giant planets in the HR 8799 system, 130 light-years away, providing strong evidence that they formed similarly to Jupiter and Saturn. Observations reveal high levels of carbon dioxide, indicating a core accretion formation process, where solid cores slowly attracted gas from a protoplanetary disk. This breakthrough confirms JWST’s ability to analyze exoplanet atmospheres through imaging, complementing its spectroscopy capabilities. HR 8799, only 30 million years old, remains a crucial system for studying planet formation. The findings suggest these planets contain more heavy elements than previously thought, offering insight into planetary diversity. Using JWST’s NIRCam coronagraph, researchers also studied 51 Eridani, another nearby system. These observations help distinguish between giant planets and brown dwarfs, advancing our understanding of planetary evolution. Future JWST studies aim to determine how common core accretion is in directly imaged exoplanets. (ESA)
ASTRONOMERS DETECT MYSTERIOUS FAST RADIO BURST FROM DWARF GALAXY
Astronomers have detected a mysterious fast radio burst (FRB) named FRB 20190208A, originating from a tiny, faint dwarf galaxy 7 billion light-years away. This discovery is surprising, as FRBs typically come from massive, star-forming galaxies. Fast radio bursts are intense energy pulses lasting milliseconds, first discovered in 2007, and their origins remain uncertain. Scientists propose several explanations, including neutron stars with powerful magnetic fields, stellar mergers, or unknown astrophysical processes. While speculative theories suggest extraterrestrial origins, the scientific consensus points to natural astrophysical phenomena. The discovery challenges existing models of FRB formation and highlights the universe’s ongoing mysteries. As astronomer Danté Hewitt noted, the host galaxy’s low density makes this finding unexpected. This detection reinforces the idea that space remains full of surprises, continuously reshaping our understanding of cosmic phenomena. The universe, once again, proves it has more secrets waiting to be uncovered. (Union Rayo)
NEW STUDY SUGGESTS NEANDERTHALS CONSUMED MAGGOTS IN DIET
A new study challenges the long-held belief that Neanderthals were primarily hypercarnivorous hunters by suggesting they regularly consumed maggots. Neanderthal bones have high nitrogen-15 levels, traditionally linked to meat-heavy diets, but research by biological anthropologist Melanie Beasley indicates that maggots feeding on rotting tissue accumulate even higher nitrogen-15 levels. This suggests Neanderthals may have incorporated scavenged or fermented meat—and its larvae—into their diets. Beasley’s experiments at the University of Tennessee’s Body Farm found that decomposing tissue and maggots significantly increase in nitrogen-15 over time. Since maggots were abundant near carcasses, easy to collect, rich in fat, and a common food source among modern foraging societies, Beasley argues they were likely a regular part of Neanderthal diets. This finding broadens our understanding of Neanderthal food habits, reinforcing evidence that they ate plants, shellfish, and cooked grains. It also challenges traditional gender roles in prehistoric societies, as women could have easily gathered this protein-rich resource. (Science)
