Single Gene Edit Transfers Behaviors Across Species

Scientists in Japan have used genetic engineering to make a species of fruit fly perform a courtship ritual it had never done before. By turning on the “fruitless” gene in insulin-producing neurons, they rewired the brains of Drosophila melanogaster to offer regurgitated food to potential mates—a behavior seen in a different species, D. subobscura.

Maternal Inflammation May Disrupt Infant Brain Wiring

A new study reveals that inflammation during pregnancy may impair neurodevelopment in infants by reducing CD11c-positive microglia—key immune cells that support brain myelination. These cells produce IGF-1, a protein critical for forming the myelin sheath that helps nerve signals travel efficiently.

Vitamin B Deficiency in Gut Linked to Parkinson’s

A new study reveals a link between gut bacteria and Parkinson's disease (PD). Researchers found a decrease in genes responsible for synthesizing essential B vitamins in PD patients, which may weaken the intestinal barrier and lead to inflammation in the brain. This finding suggests that B vitamin supplementation could be a potential therapeutic avenue for PD.

Serotonin Boosts Fertility

Researchers uncovered a crucial link between glucose levels, serotonin signaling, and fertility. By studying rats and goats, the team discovered that increased glucose availability stimulates serotonergic neurons, enhancing the release of reproductive hormones via the activation of kisspeptin neurons.

Write It Down, Throw It Away: Easing Anger with Paper and Pen

Researchers identified an effective, straightforward method for managing anger: writing down feelings about a negative experience and then discarding the paper by shredding or throwing it away significantly reduces anger levels. This innovative study not only offers a practical anger management tool but also supports the therapeutic potential of physically interacting with objects to alter emotions.

How Human Actions Alter COVID-19 Evolution

A research group using AI and mathematical modeling has discovered that human behavioral responses to COVID-19, like lockdowns and isolation, influence the evolution of the virus. Their study found that SARS-CoV-2 variants became more transmissible early in infection due to these human interventions.

AI Reveals Distinct Speech Patterns in Parkinson’s Disease Patients

Researchers used artificial intelligence to analyze speech in Parkinson's disease patients, revealing distinct patterns. The AI found Parkinson's patients used more verbs but fewer nouns and fillers in their speech, even before cognitive decline typically associated with PD was evident. The analysis was capable of identifying Parkinson's patients with over 80% precision, offering a potential new tool for early diagnosis. This study underscores the potential of natural language processing, a branch of AI, in enhancing healthcare diagnostics.
