Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

open access: yesAdvanced Science, EarlyView.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

open access: yesAdvanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Structure and function of the musculoskeletal ovipositor system of an ichneumonid wasp

open access: yesBMC Zoology, 2018
Background Modifications of the ovipositor appear to have played a prominent role in defining the host range of parasitoid hymenopterans, highlighting an important contributing factor in shaping their oviposition strategies, life histories and ...

Marine Invertebrate-Associated Bacteria In Coral Reef Ecosystems As A New Source Of Bioactive Compounds [PDF]

open access: yes, 2004
Coral reefs are the most species-rich environments in the oceans. Reefs cover 0.2% of the ocean’s area and yet they provide home to one-third of marine fishes and to tens of thousands of other species.

Sulfakinin Signaling Sense Circulating Fructose and Suppresses Food Consumption via Insulin‐Like Peptide in Bactrocera Dorsalis

open access: yesAdvanced Science, EarlyView.
This study discovered a new pathway that tells fruit flies when to stop eating. It found that rising blood sugar (fructose) is detected by a sensor called GR43a. This triggers a chain reaction involving the satiety signal sulfakinin and its receptor, ultimately activating a final satiety signal, ILP5.

Southern California fisheries monitoring summary for 1993 and 1994 [PDF]

open access: yes, 1997
The southern California Monitoring and Management Units collectively gathered 803 discrete samples of 7,329 marine finfishes and invertebrates from local commercial fish markets or authorized fish transporters in 1993.

Spatial variability in the hyporheic zone refugium of temporary streams [PDF]

open access: yes, 2011
A key ecological role hypothesized for the hyporheic zone is as a refugium that promotes survival of benthic invertebrates during adverse conditions in the surface stream.

The Potential of Arable Weeds to Reverse Invertebrate Declines and Associated Ecosystem Services in Cereal Crops [PDF]

open access: yes, 2020
There is global concern that invertebrate populations are declining rapidly, particularly in agricultural habitats. Declines have been attributed to the intensification of farming systems, with many studies focussing on a lack of semi-natural habitat in ...

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

open access: yesAdvanced Science, EarlyView.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

Environmental concentrations of metals (Cu and Zn) differently affect the life history traits of a model freshwater ostracod

open access: yesThe European Zoological Journal
Zinc (Zn) and copper (Cu) are common contaminants of inland water bodies under severe anthropogenic pressure. The main aim of this study was to test the influence of environmental aqueous concentrations of Zn and Cu on the fitness-related life history ...
