Dog Brains Differentiate Human Anger, Fear, and Sadness

Summary: A new study demonstrated that dogs possess specialized neural networks for processing human facial expressions. The team used functional magnetic resonance imaging (fMRI) and machine learning to analyze canine…

Sad or afraid? Dogs may be able to read your face

A new brain-imaging study suggests that dogs may be able to distinguish between certain negative human emotions just by looking at people’s faces.

Prefrontal Cortex Can Block Creative Problem-Solving

Summary: Researchers discovered an unexpected role for the medial prefrontal cortex (mPFC), a region traditionally viewed as the executive driver of behavioral flexibility. The team demonstrated that the mPFC can…

Exercise Shields Dopamine Neurons in Parkinson’s

Summary: Researchers synthesized evidence from 129 studies detailing how exercise-induced muscle signaling protects against Parkinson’s disease (PD) pathology. The authors examine the biological impact of sarcopenia, the progressive loss of…

Why Psychedelics Make Everything Feel Deeply Connected

Summary: Researchers introduce “apical hypercontextualisation”—a bottom-up neurobiological mechanism explaining how psychedelics (psilocybin, LSD, DMT, mescaline) transform perception and cognition. Moving beyond macro-scale whole-brain neuroimaging, the framework focuses on the cellular…

Receptor Density Shapes Whole-Brain Network Dynamics

Summary: Researchers developed a biologically grounded whole-brain computer model that bridges microscopic molecular chemistry with macroscopic neural activity. The team integrated detailed empirical maps of muscarinic acetylcholine receptor density across…

Early Stress Heightens Adult Anxiety

Summary: Researchers uncovered a fundamental epigenetic mechanism explaining how early-life adversity permanently alters the brain’s stress response networks. The study identified that childhood trauma increases levels of the enzyme SETD7…

How Overconfidence and Loss Aversion Co-Evolved

Summary: Researchers propose an evolutionary resolution to why human overconfidence persists despite causing costly decision-making errors. The study argues that overconfidence functions analogously to a peacock’s tail: a costly evolutionary…

Selling sickness: How RFK Jr. and wellness influence grifters turned “inflammation” into a racket

While some health advocates believe raising awareness about inflammation is important, the MAHA movement has twisted it, devaluing the struggles chronically ill people with inflammatory disorders actually face. … This inflammation…

Peripheral Blood Cells Replenish Aging Human Microglia

Summary: Researchers revealed that aging leads to a massive, previously unrecognized migration of peripheral blood stem cell-derived immune cells into the human brain. The team dismantled the long-held dogma that…
