Large language models (LLMs) can synthesize vast amounts of information. Luo et al. show that LLMs—especially BrainGPT, an LLM the authors tuned on the neuroscience literature—outperform experts in predicting neuroscience results and could assist scientists in making future discoveries.
This study explores the development of Group-IV semiconductor lasers for cryogenic applications, demonstrating continuous-wave operation at low current densities and highlighting the potential for integration into silicon-based photonic systems.
Facebook, Instagram, Threads, and WhatsApp suffered a massive worldwide Wednesday afternoon, with services impacted in varying degrees based on user’s region.
According to DownDetector, the outage occurred at approximately 12:40 PM ET, with many users unable to access the services through the websites and apps or send messages through WhatsApp.
When users attempted to access Facebook, they were greeted with errors stating, “Sorry, something went wrong. We’re working on getting this fixed as soon as we can.”
Over 390,000 WordPress credentials exfiltrated via malicious GitHub repository hosting trojanized PoC code.
US scientists achieve a groundbreaking 10 GeV electron acceleration in just 30 cm using a novel dual-laser and supersonic gas jet system.
The use of antidepressants during pregnancy significantly increased the risk of a child experiencing functional constipation—a common DGBI that may be painful—during their first year of life. “After adjusting for covariates, SSRI/SNRI exposure was associated with an over 3-fold increased risk for functional constipation,” the investigators wrote.
“We found that, at the age of one, 63% of children exposed to antidepressants during pregnancy experienced constipation, compared with 31% of children whose mothers did not take medication,” said study co-author Larissa Takser, MD, professor of pediatrics at the Université de Sherbrooke in Québec. “This finding suggests a potential connection between serotonin levels in utero and gut development, and opens new doors to examine SSRI properties not previously studied.”
The investigators’ collective findings point to a promising avenue of future studies: the gut epithelium as a new and potentially safer target for treating mood disorders, particularly for pregnant women. “Together, these data define a novel potential mechanism for gut-brain communication and identify intestinal epithelial 5-HT as a new and potentially safer therapeutic target for mood regulation,” the authors stated.

Psychological studies have shown that the way humans respond to others’ emotions is strongly influenced by their own past emotional experiences. When a similar emotional situation—such as a past stressful event—is observed in another person, we can react in two different ways. On one hand, it may generate empathy, enhancing the ability to understand others’ problems and increasing sensitivity to others altered emotions. On the other hand, it may induce self-distress resulting into an avoidance towards others.
The research group at IIT has demonstrated that a similar phenomenon also occurs in animals: recalling a negative experience strongly influences how an individual responds to another who is experiencing that same altered emotional state. More specifically, animals exhibit different reactions only if the negative event they experienced in the past is identical to the one they observe in others. This indicates that even animals can specifically recognize an emotional state and react accordingly even without directly seeing the triggering stimuli.
