Taxonomic Definition

The Actiniaria are an order of soft-bodied, predatory marine invertebrates within the class Anthozoa and the phylum Cnidaria. Exclusively polypoid in structure, lacking a medusa stage, they attach primarily to hard benthic substrates via an adhesive pedal disc, though some species burrow in soft sediment or float pelagically. Distributed across all marine environments from the intertidal zone to the hadal trenches, Actiniaria represent one of the most diverse groups of hexacorallians.

Using 100-year-old data to help predict future solar cycle activity

To reconstruct the Sun’s polar magnetic behavior over more than 100 years, an SwRI scientist first corrected anomalies in historical data from Kodaikanal Solar Observatory (KoSO) to sync with direct modern measurements of the Sun’s poles. Comparing observations from KoSO in Calcium-K light with magnetic field measurements from the Solar and Heliospheric Observatory’s Michelson Doppler Imager (left) highlights the association of bright regions in Ca K with magnetic activity in the Sun. The right image shows dark blue and green (north polarity) yellow and orange regions (south polarity) regions, indicating where Ca K light and magnetic data are highly correlated.

Scientific Frontline: "At a Glance" Summary

• Main Discovery: The expansion of human settlements into the Amazon rainforest, specifically the growing interface between urban areas and forests, is the primary driver behind the recent resurgence of human yellow fever spillover cases.
• Methodology: Researchers analyzed yellow fever case records from Brazil (2000–2021), Colombia (2007–2021), and Peru (2016–2021) alongside land-use data from the MapBiomas Project, modeling the relationship between disease rates and geographic metrics such as forest patch size, edge density, and forest-urban adjacency.
• Key Data: A 10% increase in forest-urban adjacency raised the probability of a spillover event by 0.09, equivalent to a 150% increase in the number of spillover events annually; notably, this high-risk borderland is expanding by approximately 13% per year.
• Significance: Proximity between human settlements and forest edges is a significantly stronger predictor of disease spillover than ecological forest fragmentation alone, raising critical concerns that urban transmission cycles—independent of non-human hosts—could reemerge.
• Future Application: Findings indicate a critical need to realign public health infrastructure and vaccination stockpiles to specifically target expanding forest-urban interfaces, rather than relying solely on broad ecological conservation metrics.
• Branch of Science: Disease Ecology and Epidemiology
• Additional Detail: Recent data highlights the urgency, with confirmed yellow fever cases in 2025 showing a threefold increase compared to 2024 and shifting geographically to areas outside the Amazon basin.

Scientific Frontline: Extended "At a Glance" Summary

The Core Concept: The ARKS (ALMA survey to Resolve exoKuiper belt Substructures) program is an international astronomical survey that has captured the first high-resolution images of debris disks, which represent the chaotic "teenage" phase of planetary system evolution.

Key Distinction/Mechanism: Unlike the bright, gas-rich disks of newborn planets ("baby pictures"), these "teenage" systems are fainter dusty belts that exist after planets have formed but before the system settles into adulthood; the survey utilizes the Atacama Large Millimeter/submillimeter Array (ALMA) to resolve minute details like dust grains and carbon monoxide gas, revealing complex substructures rather than simple, uniform rings.

Origin/History: The survey team, led by the University of Exeter, secured approximately 300 hours of observation time at the ALMA observatory between October 2022 and July 2024, with findings published in a series of papers in Astronomy & Astrophysics.

Scientific Frontline: "At a Glance" Summary

• Main Discovery: Hot spring bathing behaviors in Japanese macaques actively reshape the host "holobiont," specifically modifying lice distribution and gut microbiota composition beyond simple thermoregulation or stress relief.
• Methodology: Researchers conducted a comparative study over two winters at Jigokudani Snow Monkey Park, utilizing behavioral observations, ectoparasite monitoring, and gut microbiome sequencing to analyze differences between female macaques that bathed regularly and those that did not.
• Key Data: Bathers exhibited distinct lice distribution patterns (suggesting disruption of activity or egg placement) and a lower abundance of specific bacterial genera, yet showed no increase in intestinal parasite infection rates or intensity despite sharing communal water sources.
• Significance: The study provides empirical evidence that voluntary animal behaviors act as direct drivers of host-parasite and host-microbe interactions, challenging the assumption that shared water sources in the wild necessarily amplify disease transmission risks.
• Future Application: Insights from this research will aid in modeling the co-evolution of behavior and health in social animals and offer comparative frameworks for understanding how cultural practices, such as communal bathing, influence microbial exposure in primates.
• Branch of Science: Primatology, Ethology, and Microbial Ecology
• Additional Detail: The findings underscore the concept of the holobiont—an integrated system of the host and its symbiotic organisms—as a dynamic entity modulated by behavioral choices rather than solely by environmental constraints.
