โEmbracing โAnti-Vaxโ:CHDโs Austin Gatheringโ
At a Childrenโs Health Defense โMoment of Truthโ conference in Austin, Texas, attendees openly embraced the โanti-vaxโ label long rejected by Robert F. Kennedy Jr., now health secretary, who did not attend but loomed large via merchandise and tributes. Speakers including Del Bigtree and MAHA Institute president Mark Gorton urged a bolder anti-vaccine stance, while CHD scientist Brian Hooker voiced caution, saying heโd support immunization during a convincingly dire epidemic. The event mixed fervor and grievance, featuring senators Rand Paul and Ron Johnson (virtually), Florida surgeon general Joseph Ladapo, and Andrew Wakefield, lauded despite his retracted study. Panels showcased the contentious โspellers methodโ for nonverbal autism. Skeptical claimsโsuch as Bill Gates pushing subdermal โelectric tattoosโโsurfaced alongside broader denunciations of surveillance, pandemic mandates, and perceived media and medical gaslighting.

High MDR Burden Documented in West Bank Hospitals
A cross-sectional study of 10,007 clinical isolates from 13 West Bank government hospitals (2023) found 36.7% were multidrug-resistant (MDR). Escherichia coli was most common (43% of isolates). MDR rates were highest in Acinetobacter baumannii (76.4%), ESBL-producing Klebsiella pneumoniae (69.2%), and ESBL-producing E coli (58.3); Staphylococcus aureus showed 29.5% MDR. Demographic modeling linked MDR to male sex (aOR 1.14) and increasing age, with the highest odds in adults โฅ65 years (aOR 1.85). Children 2โ9 and 9โ16 years had lower odds (aORs 0.69 and 0.66 vs <2 years). Authors cite antibiotic misuse, over-the-counter access, and weak infection control within a fragmented health system, urging context-specific interventions and stronger antimicrobial stewardship spanning community and hospital settings.

AI speeds up radio-signal hunts by ~600ร
Astronomy & Astrophysics highlighted a machine-learning pipeline that accelerates detection of faint astrophysical signalsโpulsars, fast radio bursts, technosignature candidatesโby roughly six hundredfold versus standard workflows. The system triages petabyte-scale radio data streams in nearโreal time, suppressing radio-frequency interference and ranking candidates for human follow-up. Benchmarks on archival surveys show substantially higher recall at the same false-positive rate, and tests on live feeds demonstrated timely identification of sub-threshold bursts that conventional filters miss. The team argues this makes wide-field, multi-beam instruments far more efficient and could be pivotal as next-generation arrays (e.g., SKA) come online. They outline plans to open-source trained models and expand to cross-matching with optical transients. (A&A)
Dwarf galaxies narrow the dark matter vs. modified gravity debate
A new analysis of rotation curves and stellar dynamics in nearby dwarf galaxies finds their mass profiles better match cold dark matter predictions than modified gravity alone. Using high-resolution spectroscopy and updated distance estimates, researchers disentangled baryonic feedback (e.g., supernova-driven โcoresโ) from underlying halo structure. The work substantially reduces long-standing tensions by showing that observed inner-density slopes can emerge naturally from ฮCDM when realistic star-formation histories are included. It doesnโt fully rule out modified gravity, but limits parameter ranges needed to fit the same dwarfs. Follow-up with IFU spectroscopy and deep imaging is proposed to test residual degeneracies.

Black hole shadows as stress tests for Einstein
A Nature Astronomy study proposes a rigorous framework for using black hole โshadowโ images to test general relativity against alternative gravity theories. Teams simulated plasma, magnetic fields, and light propagation around black holes across multiple theories to predict subtle, theory-specific differences in shadow size and morphology. Current Event Horizon Telescope images of M87* and Sgr A* canโt separate models cleanly, but the authors show next-generation Earth/space-baseline interferometry with subโmicroarcsecond resolution could. Some exotic options (e.g., wormholes, naked singularities) are already disfavored; improved angular resolution should tighten constraints on deviations from GR. The roadmap clarifies what instrumental upgrades matter most. (SciTechDaily)
Record-breaking black hole โsuperflareโ 10 billion light-years away
Astronomers report the most luminous, most distant flare ever recorded from a supermassive black hole, likely a tidal disruption event inside an active galactic nucleus. First flagged by the Zwicky Transient Facility and tracked with Keck and other observatories, the outburst brightened by a factor of ~40 and radiated ~10 trillion solar luminosities at peak. Spectra and long-lived evolution argue a massive star (โฅ30 Mโ) was torn apart, with cosmological time dilation stretching the event as observed on Earth. The find suggests TDEs can be extreme inside AGN disks and highlights the value of persistent time-domain surveys ahead of Rubin Observatory operations. (phys.org)

Euclidโs extra eight years could transform astrometry
An astronomer proposes a clever โsecond actโ for ESAโs Euclid: repeat its sky-mapping campaign during an eight-year fuel surplus to derive exquisite proper motions for ultra-faint sources beyond Gaiaโs reach. A โthird epochโ could even attempt limited parallax on select fields. Because Euclid probes 5โ6 magnitudes fainter than Gaia, pairing epochs would expand the Milky Wayโs dynamical census to billions of dim stars and background galaxies, sharpen lensing calibrations, and refine dark matter substructure tests. Engineering challenges remain, but the concept leverages existing hardware and operations. Itโs a nimble way to multiply Euclidโs cosmology return with minimal cost.(Universe Today)
Chinaโs Mars orbiter snaps the interstellar comet 3I/ATLAS
Chinaโs Tianwen-1 orbiter captured images of interstellar comet 3I/ATLAS from ~30 million km as it swept past Mars, stitching frames into an animation of the inbound trajectory. The observationโamong the closest space-based views to dateโcomplements Hubble/JWST and ground-based campaigns around perihelion. Mission teams overcame challenges posed by the objectโs small size (~5.6 km) and extreme relative speeds. Images show a coma and tail consistent with volatile outgassing, reinforcing 3I/ATLASโs cometary nature and setting the stage for future ISO intercept concepts (e.g., ESAโs Comet Interceptor).

JWST finds complex organics in protostar iceโoutside the Milky Way
Using JWST/MIRI, astronomers detected complex organic molecules frozen in dust-grain ices around a massive protostar (ST6) in the Large Magellanic Cloudโthe first such detection beyond the Milky Way. Confirmed species include acetaldehyde, acetic acid, ethanol, methanol, and methyl formate; additional lines suggest even more COMs such as glycolaldehyde. Because the LMC has lower heavy-element abundance and stronger UV fields than the Milky Way, the chemistry offers a window into how prebiotic building blocks formed under โearly-universeโlikeโ conditions. The team notes COM ice abundances are generally lower than Galactic protostars, except acetic acid, likely boosted by UV processing. (space.com)
Long-sought twisting magnetic waves spotted in the solar corona
Using the Daniel K. Inouye Solar Telescope, solar physicists directly observed small-scale, torsional Alfvรฉn waves twisting through the Sunโs corona. These ever-present magnetic waves are a prime candidate for transporting energy from the turbulent lower atmosphere upward, potentially explaining why the corona is hotter than the photosphereโa long-standing solar mystery. The measurements capture the wavesโ magnetic and velocity signatures and distinguish them from flare-driven disturbances. If their ubiquity and energy flux hold across regions, they could substantially contribute to coronal heating and solar wind acceleration. The result motivates coordinated DKISTโSDO campaigns to map energy budgets across solar cycles. (Space)
Rubin Observatory spots a surprise โtailโ on Messier 61
Early imaging from the Vera C. Rubin Observatory revealed a faint, extended โtailโ feature associated with starburst galaxy M61 in Virgo, hinting at recent interactions or outflows shaping its evolution. The result showcases Rubinโs wide, deep, and rapid survey powerโeven in pre-survey testingโand previews how its Legacy Survey of Space and Time will uncover low-surface-brightness structures around galaxies, from stellar streams to tidal debris. Such features record assembly histories and dark-matter halo properties. Astronomers now plan follow-ups to pin down the tailโs origin and connect it to M61โs prolific supernova history and high star-formation rate. (Scientific American)
