Assaying Blood Cell Populations of the Drosophila melanogaster Larva

open access: yesJournal of Visualized Experiments, 2015
In vertebrates, hematopoiesis is regulated by inductive microenvironments (niches). Likewise, in the invertebrate model organism Drosophila melanogaster, inductive microenvironments known as larval Hematopoietic Pockets (HPs) have been identified as ...

Bioinspired Mechanisms and Actuation of Soft Robotic Crawlers

open access: yesAdvanced Science, EarlyView.
Researchers have been developing soft materials and robotic crawlers inspired by soft‐bodied animals to mimic effective crawling in complex environments. This review explores the state‐of‐the‐art in soft crawlers, highlighting the interaction between materials, crawling mechanisms, actuation, and applications. The review concludes by providing insights

Sustainability‐Inspired Upcycling of Organophosphorus Pollutants into Phosphatic Fertilizer in a Continuous‐Flow Reactor

open access: yesAngewandte Chemie, EarlyView.
First report of organophosphorus pollutants selective degradation, via the synergistic effect of peroxymonosulfate and sodium percarbonate, into phosphates that are continually converted into phosphatic fertilizer by struvite precipitation on a continuous‐flow reactor. Abstract With the increasing requirement for phosphorus resources and their shortage

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

open access: yesAdvanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Hox genes pattern the anterior-posterior axis of the juvenile but not the larva in a maximally indirect developing invertebrate, Micrura alaskensis (Nemertea)

open access: yesBMC Biology, 2015
The pilidium larva is a novel body plan that arose within a single clade in the phylum Nemertea - the Pilidiophora. While the sister clade of the Pilidiophora and the basal nemerteans develop directly, pilidiophorans have a long-lived planktotrophic ...

Photothermal Driven Biomimetic Actuator Based on Asymmetric Microstructure Nb2CTx MXene Film

open access: yesAdvanced Electronic Materials, EarlyView.
A photothermal biomimetic actuator based on niobium carbide (Nb2CTx) MXene films is prepared, and its photothermal actuation performance is studied in terms of optical power density, bending angle, bending speed, and bending curvature. A series of experiments are conducted to explore the potential applications of this actuator in flexible crawling ...

Lethal temperatures for Rhamdia quelen larvae (Pimelodidae) Temperaturas letais de larvas de Rhamdia quelen (Pimelodidae)

open access: yesCiência Rural, 2000
The lower and upper lethal temperatures (LT50) of R. quelen larvae were determined. The larvae were obtained from two spawning periods with hatching temperatures of 21 and 26ºC respectively.
