Identity Play: Middle School Youths' Provisional Self‐Making in Horizon‐Expanding STEM Spaces

open access: yesScience Education, EarlyView.
ABSTRACT This study introduces identity play as an analytic construct for science education to explore improvisational dimensions of middle school students' STEM identity development in multiple out‐of‐school learning experiences focused on environmental problem‐solving.

Robust Bioconjugated Antigens Induce Immune Responses Preventing Malaria Infection and its Transmission

open access: yesSmall, EarlyView.
Engineered malaria antigens enable in vivo bioconjugation to submicron biopolymer particles in E. coli. Two antigens are co‐tethered at high density and defined stoichiometry. The resulting thermostable particles elicit strong, durable antibody and T‐cell responses, conferring robust protection and blocking mosquito transmission.

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

Ecological and social factors lead to variation in parental care between sexes in a burying beetle

open access: yesInsect Science, EarlyView.
We experimentally investigated the effects of ecological (resource availability and interspecific competition) and social factors (intraspecific competition) on parental care and reproductive success in the burying beetle Nicrophorus vespilloides. Our results showed that males and females adjust their parental care based on resource availability and ...

Diagnosis of \u3cem\u3eSchistosoma mansoni\u3c/em\u3e without the Stool: Comparison of Three Diagnostic Tests to Detect \u3cem\u3eSchiostosoma mansoni\u3c/em\u3e Infection from Filtered Urine in Zambia [PDF]

open access: yes, 2013
Diagnosis for intestinal Schistosoma mansoni lacks sensitivity and is arduous to conduct. The standard diagnostic tests, Kato-Katz (KK) and circulating cathodic antigen (CCA) both lack sensitivity and with KK, require obtaining, transporting, and ...

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

open access: yesInsect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Leishmania and HIV co-infection: first naturally Leishmania strain presenting decreased susceptibility to miltefosine, recovered from a patient in Portugal

open access: yesJournal of Infection and Public Health
Background: In Europe, up to 70% of visceral leishmaniasis (VL) cases occurring in adults living with HIV. People living with HIV with VL co-infection often display persistent parasitemia, requiring chronic intermittent anti-Leishmania therapies ...

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

open access: yesInsect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

open access: yesInsect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐
