Gut bacteria send direct signals to the brain to stop you from overeating

Researchers have discovered a novel gut-brain sensory circuit in mice where specialized colonic cells sense bacterial flagellin and rapidly suppress feeding via the vagus nerve. This "neurobiotic sense" operates independently of immune pathways, revealing a direct neural mechanism for microbiota-host communication.

Digging into the past: What ancient proteins say about real medieval meals

Researchers used stable isotope and proteomic analyses on medieval European skeletons to uncover the details of ancient diets. The findings revealed a heavy reliance on C3 plants, terrestrial animal proteins, legumes, and freshwater fish, demonstrating the power of combining methods for paleodietary reconstruction.

Study reveals pandemic life made brains age faster, even without catching COVID-19

The COVID-19 pandemic accelerated biological brain aging in older adults by an average of 5.5 months over less than three years, regardless of infection status. Social disruption, age, male sex, and socioeconomic disadvantage heightened vulnerability, while only infected individuals showed measurable declines in executive function.

Research uncovers a 'neurobiotic sense' that lets the brain respond to gut microbe signals

In a breakthrough that reimagines the way the gut and brain communicate, researchers have uncovered what they call a "neurobiotic sense," a newly identified system that lets the brain respond in real time to signals from microbes living in our gut.

Teen tobacco use linked to higher rates of depression and anxiety

Adolescents who use either e-cigarettes or conventional tobacco products (CTP)-like cigarettes, cigars, hookah and pipes-are significantly more likely to report symptoms of depression and anxiety than teens who don't use tobacco products at all, according to a study published this week in the open-access journal PLOS Mental Health by Noor Abdulhay of West Virginia University, USA, and colleagues.
