Researchers have discovered a specific set of neurons in the amygdala that can trigger anxiety and social deficits when overactive. By restoring the excitability balance in this brain region, they successfully reversed these symptoms in mice. The ...

Using powerful 7-Tesla brain imaging, researchers mapped how the brainstem manages pain differently across the body. They discovered that distinct regions activate for facial versus limb pain, showing the brain's built-in precision pain control ...

Long-term melatonin use for sleep problems may come with unexpected heart dangers. Researchers found that chronic users were almost twice as likely to die and 3.5 times more likely to be hospitalized for heart failure. Though melatonin is widely ...

Researchers at McMaster University have discovered that the eyes may offer a powerful, non-invasive way to assess heart health and biological aging. By analyzing retinal scans alongside genetic and blood data from over 74,000 participants, they found ...

Researchers found that embodying a digital, childlike version of one's own face helps unlock vivid childhood memories. This illusion strengthens the connection between bodily self-perception and autobiographical recall. The findings suggest that ...

UC San Diego researchers combined artificial intelligence with molecular biology to unravel how immune cells in the gut decide between inflammation and healing, a process gone awry in Crohn's disease. They discovered that the NOD2 gene's interaction ...

Boston researchers linked nighttime light exposure to greater stress-related brain activity and inflamed arteries, signaling a higher risk of heart disease. The study suggests that artificial light at night disrupts normal stress responses, leading . ...

Duke-NUS scientists unveiled BrainSTEM, a revolutionary single-cell map that captures the full cellular diversity of the developing human brain. The project's focus on dopamine neurons provides crucial insight for Parkinson's treatment. Their ...

Scientists uncovered how the amino acid leucine enhances mitochondrial efficiency by preserving crucial proteins that drive energy production. By downregulating the protein SEL1L, leucine prevents unnecessary degradation and strengthens the cell's .. ...

Penn State scientists uncovered an ancient bacterial defense where dormant viral DNA helps bacteria fight new viral threats. The enzyme PinQ flips bacterial genes to create protective proteins that block infection. Understanding this mechanism could ...
