Summary: In this study, we developed fast-scan cyclic voltammetry (FSCV) to measure dopamine release in fruit flies during behavior. The results showed that sugar feeding induced longer dopamine release compared to acetylcholine stimulation in the mushroom body. In addition, administering dopamine transporter inhibitor or D2 receptor antagonist significantly increased sugar-evoked dopamine release.

Summary: A multiphoton imaging method was developed to capture neural structure and activity in behaving flies through the intact cuticle, revealing high transmission at wavelengths >900nm. By compressing or removing air sacs, multiphoton imaging of the fly brain through the intact cuticle was achieved with superior results using 3-photon imaging in deeper regions. This through-cuticle imaging method extends the time limits of in vivo imaging in flies and offers new ways to study neural structure and activity in the fly brain.

Summary: This study identifies hundreds of genes selectively enriched in either the odorant receptor or ionotropic receptor subsystems in the Drosophila melanogaster antennae. The study also reveals that neuronal genes other than sensory receptors are broadly expressed within the subsystems, while many non-neuronal genes show highly selective expression. Furthermore, a specific non-neuronal molecule called Osiris 8 is found to play a crucial role in high sensitivity responses to pheromone ligands in the olfactory subsystems.

Summary: Despite the small number of gustatory sense neurons in Drosophila larvae, researchers found that neurons can be activated by different combinations of taste modalities, including opposite hedonic valence. They also identified distinct temporal dynamics of response and external sucrose sensing neurons in the larval external taste center, suggesting that external and internal gustation may use distinct and complementary mechanisms in sugar sensing.

Summary: Metastasis is a major cause of cancer mortality, and environmental carcinogens have serious effects on this process. In this study using a fruitfly model, it was found that PCB126, PFOA, and CdCl2 significantly increased tumor invasion rates and decreased larval body weight and locomotion behavior. These effects were associated with disturbances in the expression of target genes in the MAPK and UPR pathways, which were attenuated by inhibitors of p38, JNK, and IRE1. The results highlight the important role of sna/E-cad in connecting the effects of carcinogens on UPR and MAPK regulations and the resultant metastasis.

Summary: This study found that coexposure of silver compounds and polystyrene nanoplastics can alleviate the delayed fly emergence and cellular oxidative stress induced by silver compounds. Polystyrene nanoplastics can transport silver compounds across the intestinal barrier and deliver them into the hemolymph of Drosophila larvae. The antagonistic effect may be attributed to the confinement of silver by polystyrene nanoplastics, reducing its bioavailability.

Summary: This study revealed the phytochemical composition of Hymenaea courbaril L.'s resin and conducted in vivo evaluations on Drosophila, finding that the larvae were more sensitive to the partial ethanolic extract, with significant genotoxic effects observed. The absence of coumarins in the partial extract possibly makes the insect more susceptible to genetic damages.

Summary: The changes in brain lipids induced by Modafinil treatment in Drosophila melanogaster show a decrease in phosphatidylcholine and sphingomyelin species, while an increase in phosphatidylethanolamine and phosphatidylinositol levels, which is consistent with previous studies on cognition-related drugs. These alterations offer insight into the potential mechanism of action of Modafinil in the brain and provide a potential target for the treatment of certain disorders.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.

Summary: This study investigates the effect of high- and low-temperature environments on the charge-discharge performance of a Li-ion battery. The deterioration mechanisms of the battery at different temperatures are analyzed through various characterization techniques. The results indicate that the battery performance deteriorates more significantly at a low-temperature environment of 5 degrees C compared to higher temperatures. The understanding of the deterioration mechanisms can contribute to the development of safer battery usage methods.

Summary: The spatial distribution of enzymes on electrodes is important for bioelectrocatalysis. In this study, controlled spatial distribution of gold nanoparticles on Ti nanodimples was achieved. The efficiency of enzymatic O2 reduction was found to be influenced by the size of the gold nanoparticles and their colocalization with TiO2. The highest stability of enzymatic current was observed with the largest gold nanoparticles.

Summary: The use of Lithium-Ion Batteries (LIBs) is becoming increasingly extensive, and it is important to optimize the devices to achieve their maximum practical specific capacity. In this study, mixed ionic-electronic conducting (MIEC) binders based on PEDOT:PSS and PEDOT: PDADMA-TFSI were developed for Li-ion cathodes, and their performance was compared with conventional formulations. The influence of electrode formulations, including the addition of conducting carbon and an Organic Ionic Plastic Cristal (OIPC), was also analyzed. The proposed binders showed improved performance compared to conventional formulations with different electrolyte types and active materials.
