Tank formation transforms nitrogen metabolism of an epiphytic bromeliad and its phyllosphere bacteria.

Premise: Up to half of tropical forest plant species grow on other plants. Lacking access to soils, vascular epiphytes have unique adaptations for mineral nutrition. Among the most distinctive is the tank growth form of certain large bromeliads, which absorb nutrients that are cycled by complex microbial communities in water trapped among their overlapping leaf bases.

Paranoia and Social Anxiety: Predicting Aggressive Behavior.

Aggression is a transdiagnostic behavior that is associated with poor clinical outcomes. As such, it is important to understand factors that contribute to various manifestations of aggressive behavior. Recent research has revealed a subtype of individuals with social anxiety disorder (SAD) who tend to display relatively high amounts of aggression and experience more severe social anxiety and dysfunction compared to individuals in the prototypical SAD group.

Findings from the First Year of a Federally Funded, Direct-to-Consumer HIV Self-Test Distribution Program - United States, March 2023-March 2024.

In September 2022, CDC funded a nationwide program, Together TakeMeHome (TTMH), to expand distribution of HIV self-tests (HIVSTs) directly to consumers by mail through an online ordering portal. To publicize the availability of HIVSTs to priority audiences, particularly those disproportionately affected by HIV, CDC promoted this program through established partnerships and tailored resources from its Let's Stop HIV Together social marketing campaign. The online portal launched March 14, 2023, and through March 13, 2024, distributed 443,813 tests to 219,360 persons.

Message Framing Strategies to Promote the Uptake of PrEP: Results from Formative Research with Diverse Adult Populations in the United States.

There are no evidence-based recommendations for communicating about pre-exposure prophylaxis (PrEP) as part of a broader HIV-prevention messaging approach. To inform future message development related to PrEP uptake, we interviewed 235 individuals across ten locations in the U.S.

Effectiveness of side-inlet vegetated filter strips at trapping pesticides from agricultural runoff.

Agriculture can be a contributor of pollutants, including pesticides and excess sediment, to aquatic environments. However, side-inlet vegetated filter strips (VFSs), which are planted around the upstream side of culverts draining agricultural fields, may provide reductions in pesticide and sediment losses from agricultural fields, and have the additional benefit of removing less land from production than traditional VFS. In this study, reductions of runoff, the soluble pesticide acetochlor, and total suspended solids were estimated using a paired watershed field study and coupled PRZM/VFSMOD modeling for two treatment watersheds with source to buffer area ratios (SBAR) of 80:1 (SI-A) and 481:1 (SI-B).
