Article Synopsis
- Scientists studied how different kinds of flies sleep and found that desert flies sleep a lot more than common flies.
- The desert fly D. mojavensis has special sleep patterns that help it survive in tough conditions, like not having enough food.
- By disrupting their sleep with constant light, they discovered that these desert flies struggle more when they don't eat, showing that sleep is super important for their survival.
Article Synopsis
- Sleep patterns vary widely across species, and research on fruit flies helps understand these differences.
- A specific desert-adapted fly species shows a significant increase in sleep, indicating a high need for sleep while maintaining sleep homeostasis.
- This fly species also exhibits changes in sleep-related neurochemicals and displays sleep responses tied to survival in harsh conditions, suggesting it’s a valuable model for studying sleep strategies in extreme environments.
Presumed Copperhead Snakebite and Antivenom Administration in the Third Trimester.

Snake envenomation during pregnancy is an uncommon emergency with several potential complications associated with the poisoning and its treatment. This case discusses a 27-y-old gravida 3, para 1102 (3 total pregnancies, 1 term birth, 1 premature birth, 0 abortions, 2 living births, twins) at 36 wk gestation who was bitten by a presumed Agkistrodon contortrix (copperhead snake). She had worsening pain and swelling in the right lower limb.

- The ketogenic diet (KD) can help treat certain types of epilepsy by changing the bacteria in our guts.
- In experiments with mice, having good gut bacteria was important for the diet to protect against seizures.
- The study found that when certain good bacteria were added, or when mess-up in certain chemicals was fixed, the mice had better chances of not having seizures.
The microbiota is increasingly recognized for its ability to influence the development and function of the nervous system and several complex host behaviors. In this review, we discuss emerging roles for the gut microbiota in modulating host social and communicative behavior, stressor-induced behavior, and performance in learning and memory tasks. We summarize effects of the microbiota on host neurophysiology, including brain microstructure, gene expression, and neurochemical metabolism across regions of the amygdala, hippocampus, frontal cortex, and hypothalamus.

- The GI tract has a lot of a chemical called serotonin, which affects how our body works, but we don't fully understand how it is made there.
- Researchers found that special bacteria in our gut help create more serotonin by working with specific cells.
- These bacteria and their byproducts can change how we digest food and how our blood works, showing that our gut and the bacteria living in it are really important for our health.
Stress often disrupts behavior and can lead to psychiatric illness. Considerable evidence suggests that corticotropin-releasing factor (CRF) plays an important role in regulating the effects of stress. CRF administration produces stress-like effects in humans and laboratory animals, and CRF levels are elevated in individuals with stress-related illness.

Many such behaviors are triggered by host odors, but little is known about either the specific olfactory cues that trigger these behaviors or the underlying neural circuits. Heterorhabditis bacteriophora and Steinernema carpocapsae are phylogenetically distant insect-parasitic nematodes whose host-seeking and host-invasion behavior resembles that of some devastating human- and plant-parasitic nematodes.
