How You Take Your Coffee May Impact Your Risk of Early Death

A new study finds that drinking 1–2 cups of black or lightly sweetened coffee per day is associated with a lower risk of death from all causes and cardiovascular disease. Using national survey data from over 46,000 adults, researchers found a 14–17% reduction in mortality risk among moderate coffee drinkers, but only when sugar and saturated fat were kept low.

Dormant Stem Cells May Hold Key to Restoring Sense of Smell

Researchers have created a 3D mouse organoid model to study how neurons in the nose regenerate, revealing that a type of stem cell once considered dormant may be crucial for repairing olfactory tissue. The team found that horizontal basal cells (HBCs), marked by KRT5, actively support new neuron generation alongside globose basal cells (GBCs).

Low Vitamin K Intake May Accelerate Age-Related Memory Decline

A new study reveals that insufficient vitamin K may harm brain health and memory as we age. In rodent models, a vitamin K-deficient diet led to increased brain inflammation and fewer newly formed neurons in the hippocampus—key factors in learning and memory.

Early Life Stress Rewires Brain Circuits Linked to Social Motivation

New research shows that early life stress disrupts dopamine signaling, altering social motivation and behavior. Scientists found that mice raised in stressful conditions were less likely to engage in social interactions compared to those with enriched experiences.

Head Trauma May Reactivate Dormant Viruses, Increasing Alzheimer’s Risk

New research suggests that concussions and repetitive head trauma may reactivate dormant viruses like HSV-1 in the brain, potentially triggering neurodegenerative diseases such as Alzheimer’s. Using a brain tissue model, scientists observed that head trauma caused latent HSV-1 to awaken, leading to hallmark Alzheimer’s markers such as amyloid plaques, inflammation, and neuronal damage.

Brain Struggles with Conflicting Information in Schizophrenia

Researchers have developed a potential diagnostic tool for schizophrenia by observing how patients process conflicting information. By analyzing neural activity between the cortex and thalamus, they found distinct patterns that make schizophrenia patients more sensitive to uncertainty.

Plant Protein-Based Diet Is Key to Healthier Aging for Women

A new study reveals that women consuming higher amounts of plant-based protein experience fewer chronic diseases and maintain better health as they age. Analyzing data from over 48,000 women in the Harvard-based Nurses' Health Study, the research showed a significant link between plant protein intake and reduced risk of heart disease, cancer, diabetes, and cognitive decline. Protein source matters, with plant proteins being more beneficial for long-term health compared to animal proteins.

Anthrobots: Tiny Biobots From Human Cells Heal Neurons

Researchers developed 'Anthrobots,' microscopic biological robots made from human tracheal cells, demonstrating potential in healing and regenerative medicine. These self-assembling multicellular robots, ranging from hair-width to pencil-point size, show remarkable healing effects, particularly in neuron growth across damaged areas in lab conditions.

Neurosteroid Deficits Leads to Depressed Behavior

Chronic stress impairs allopregnanolone production in the basolateral amygdala, a brain area associated with mediating emotional response. The reduction of this neurosteroid results in depressive symptoms in animal models.
