Secretory Phospholipases A2 in Plants [PDF]

open access: yes, 2019
Secreted phospholipases (sPLA2s) in plants are a growing group of enzymes that catalyze the hydrolysis of sn-2 glycerophospholipids to lysophospholipids and free fatty acids. Until today, around only 20 sPLA2s were reported from plants.

Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

Relationship among Apis mellifera L. stings, swarming and climate conditions in the city of Rio Claro, SP, Brazil

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2010
The presence of bees (Apis mellifera L.) in urban areas has increased in recent years due to environmental disturbances caused by humans. Bee migration to cities may provoke serious accidents, since some people present allergic reactions to their venoms.

Predictability of bee community composition after floral removals differs by floral trait group [PDF]

open access: yesBiology Letters, 2017
Plant–bee visitor communities are complex networks. While studies show that deleting nodes alters network topology, predicting these changes in the field remains difficult. Here, a simple trait-based approach is tested for predicting bee community composition following disturbance.

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

open access: yesAdvanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Beehavior and Beyond: Realizations in Research [PDF]

open access: yes, 2015
Most people would mistake the small carpenter bee Ceratina calcarata and its relatives for ants with wings,and I won’t pretend that I could tell the difference before I spent a summer researching this particular bee species.

A Shape‐Adaptive, Performance‐Programmable, Self‐Healable and On‐Demand Destructible Robotic Skin via Self‐Strengthening Dynamic Silicone

open access: yesAdvanced Science, EarlyView.
Enabled by the distinctive inter‐ and intra‐chain siloxane exchange in commercially available silicones as the dielectric layer, the omni‐adaptive robotic skin (OmniAdapt) integrates multiple advanced functionalities: programmable sensing performance via the self‐stiffening dielectric material, application as BPM sensor, shape adaptivity for electronic

The Worker Flow at the Hive Entrance Predicts When Nest Cleaning is Intensified in Stingless Bees

open access: yesPsyche: A Journal of Entomology
Waste produced by living organisms is commonly disposed of as a prophylactic measure to avoid the spread of diseases and parasite infestation. For social insects, a proportion of workers is allocated to dispose the waste material outside the colony’s ...

Microfluidic Electrochemical Biosensor for the Detection of Platelet Factor 4 Antibody‐Mediated Thrombotic Disorders

open access: yesAdvanced Science, EarlyView.
A microfluidic electrochemical biosensor enables sensitive and specific detection of antibodies associated with vaccine‐induced immune thrombotic thrombocytopenia (VITT) and heparin‐induced thrombocytopenia (HIT). The platform uses two antigen targets— platelet factor 4 (PF4) and cross‐linked‐PF4 (c‐PF4)—and microliter volumes of patient sera to ...
