Study Reveals Precise Brain Targets Could Improve Deep Brain Stimulation Outcomes for Depression

A new study has pinpointed three key brain pathways that appear to be crucial for achieving durable relief from severe, treatment-resistant depression using deep brain stimulation (DBS). The research highlights that electrode placement—down to the millimeter—may be the deciding factor between success and failure in this intervention.

Spaceflight Alters Gene Expression: What We Know So Far

A growing body of research is mapping how extended time in space reshapes human biology at the molecular level. Studies examining astronauts and simulated spaceflight conditions have documented changes in gene expression, DNA methylation patterns, and cellular aging markers. Key findings from longitudinal studies indicate that spaceflight triggers measurable shifts

The Protective Brain Cells That May Drive Cognitive Decline

A Surprising Culprit in Age-Related Memory Loss Scientists have identified a unexpected contributor to cognitive decline in aging: cells that were long assumed to be protective. The findings challenge conventional understanding of how the aging brain deteriorates. The Role of Myelin-Producing Cells The research focuses on oligodendrocyte precursor

Stanford Researchers Unveil Label-Free Microscope for Real-Time Living Cell Imaging

A New Window into Living Cells Stanford researchers have developed a microscopy technique that can peer into living cells without the fluorescent markers traditionally required for detailed imaging. These labels, while useful, can sometimes interfere with cellular processes and require time-consuming preparation. The new approach allows scientists to observe

Study Reveals Microplastics Can Interact With Water, Raising Biological Concerns

A new study challenges the long-held assumption that plastic is biologically inactive. While plastics are generally considered inert materials, researchers have found that microplastics—tiny plastic particles measuring less than 5 millimeters—have the potential to interact with water at the molecular level. Water is one of the most

American Medical Association Releases Governance Framework for Agentic AI in Healthcare

Overview The American Medical Association (AMA) has announced a comprehensive governance framework for agentic AI solutions in healthcare settings. This initiative addresses the growing need for structured oversight of AI systems capable of autonomous decision-making in medical environments. Framework Purpose Agentic AI refers to AI systems that can independently

RFK Jr. Proposal on Unproven Peptides Draws FDA Scientist Pushback

A reported proposal by Health Secretary Robert F. Kennedy Jr. to have the FDA overlook unproven peptide products has drawn sharp criticism from agency scientists, according to reporting by Ars Technica. Peptides—short chains of amino acids used in supplements and some therapeutic applications—have grown in popularity, but FDA
