Researchers at Tulane University have identified brain circuits that help determine how fear responses change as perceived threats diminish, providing insight into how the brain regulates defensive behavior and why those processes can break down in conditions such as post-traumatic stress disorder.

Scientists have long studied the role of dopamine, a chemical in the brain that helps control learning and movement, to better understand Parkinson’s disease, schizophrenia and depression – afflictions caused in part by disruptions or changes in dopamine activity. Source link
More than 50 years after Agent Orange was used in Vietnam, a new national study published in Blood Advances highlights genetic changes that link exposure to Agent Orange to myelodysplastic syndrome (MDS), a group of bone marrow cancers that can progress to acute leukemia. The findings shed light on why some veterans develop more serious…
Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by differences in the way people interact with others, as well as restricted interests and repetitive patterns of behavior. Previous studies have observed specific differences in brain development in many autistic individuals, which typically emerge during the early stages of life. Source link
As Affordable Care Act subsidies expire at the end of 2025, Americans are undoubtedly facing a lot of confusing information about health care costs and insurance plans. Source link
Twenty-five years into their diabetes and youth research, Professor of Epidemiology Angela Liese and her team are increasing our understanding of this uniquely vulnerable population. The team’s recent findings show that youth and young adults who have diabetes and experience food insecurity have higher rates of mental health symptoms, including disordered eating. Source link
Artificial intelligence (AI) based ECG interpretation outperformed standard routes for detecting occlusive myocardial infarction (MI), according to a study presented at ESC Acute Cardiovascular Care 2026, the annual congress of the Association for Acute Cardiovascular Care (ACVC), a branch of the European Society of Cardiology (ESC).

Researchers at the Graz University of Technology (TU Graz) have developed an innovative virtual reality (VR) system that could make the treatment of arachnophobia, also known as spider phobia, more targeted and personalized in the future. This work has been published in the journal Frontiers in Human Neuroscience. Source link
A research team affiliated with UNIST has made an important discovery that explains why liver cancers associated with obesity and metabolic disorders are more aggressive and less responsive to conventional treatments. Study shows that a specific signaling pathway involving endotrophin—a protein secreted during liver fibrosis—and the receptor protein CD44 promotes tumor malignancy and drug resistance….
Amyloid beta and tau proteins compete for the same binding sites on microtubules in neurons, suggesting that displacement of tau by amyloid beta, rather than aggregation of either protein, may be the primary driver of Alzheimer’s disease pathology. Source link
