Hunger Games: A Role for cAMP.

The established dogma about regulation of feeding is based on the interaction amongst hypothalamic orexigenic and anorexigenic neuropeptides. However, the molecular underpinnings of those interactions remain unclear. A recent article published in by first demonstrated that the transition between hunger and satiety depends on the regulation of 3',5'-cyclic adenosine monophosphate (cAMP) in the paraventricular nucleus of the hypothalamus (PVH) providing novel insights on the spatial and temporal basis by which neuropeptides act.

The US biomedical research enterprise is renowned for its historical and ongoing scientific breakthroughs and advancements. Yet its capacity to solve complex health issues, bridge health equity gaps, and strengthen public trust is constrained by the lack of an overarching national vision, fragmented coordination for research funding, and critical workforce recruitment and retention challenges. To improve national health outcomes and retain global competitiveness, the sector must embrace new approaches.

Vital Directions For Health And Health Care: Priorities For 2025.

In 2016, ahead of the US presidential election, the National Academy of Medicine launched the strategic initiative Vital Directions for Health and Health Care-a series of papers on critical areas of US health care written by the nation's experts and intended to provide nonpartisan guidance to the incoming administration. The National Academy of Medicine continued the initiative in 2021. The current series, titled Vital Directions for Health and Health Care: Priorities for 2025, contains six articles on priority areas in US health and medicine that demand urgent attention.

Defect Structures in Colloidal Crystals and Their Effect on Grating Diffraction Structural Color.

Colloidal crystals of micrometer-sized colloids create prismatic structural colors through the grating diffraction of visible light. Here, we develop design rules to engineer such structural color by specifically accounting for the effect of crystal defects. The local quality and grain size of the colloidal structure are varied by performing self-assembly in the presence of a direct current (DC) electric field.

Significance of birth in the maintenance of quiescent neural stem cells.

Birth is one of the most important life events for animals. However, its significance in the developmental process is not fully understood. Here, we found that birth-induced alteration of glutamine metabolism in radial glia (RG), the embryonic neural stem cells (NSCs), is required for the acquisition of quiescence and long-term maintenance of postnatal NSCs.

Humanoid robot learning of complex behaviors with LLMs.

Insights Into the Health of Postpartum Airmen From the U.S. Air Force Fitness Database.

Introduction: Physical fitness is an integral part of military readiness, and failure to meet military Physical Fitness Assessment (PFA) standards can severely damage or end careers. Postpartum active duty service members experience a drop in PFA scores and passing rates compared to their pre-pregnancy assessments. Each branch recently extended recovery time to 12 months, but more research is required to see if this change alone is enough to return both active duty and reserve component postpartum personnel to their own preconception PFA outcomes (scores, passing rates, and injury rates) and those of a control group of nullpartum female airmen.

The undertold story: A leadership program to expand recognition of the importance of early childhood experiences.

There are considerable data documenting the importance of early experiences for healthy human development. Though widely accepted amongst mental health clinicians, developmental researchers and early childhood policymakers, this information is not well known by much of the public. We describe a specialized program designed for established and emerging leaders in Louisiana, United States of America, to help them become better informed to take action to support young children and their families and to facilitate connections across sectors for greater impact.

Who's Afraid of Murderous Rage? When Euthanasia Colludes with Self-Destructiveness.

The impact of intense countertransference affects in working with patients experiencing complex trauma can have a critical effect on decisions about euthanasia, especially when such decisions are made solely on the grounds of a psychiatric condition. These countertransference dynamics become particularly significant in the context of the rising number of euthanasia requests by psychiatric patients in the Netherlands. We contend that for a subgroup of patients with complex trauma, attachment trauma, and personality disorders, the label "treatment-resistant" may be applied prematurely and incorrectly.

Translational Outcomes Project in Neurotrauma (TOP-NT) Pre-Clinical Consortium Study: A Synopsis.

Traumatic brain injury (TBI) has long been a leading cause of death and disability, yet research has failed to successfully translate findings from the pre-clinical, animal setting into the clinic. One factor that contributes significantly to this struggle is the heterogeneity observed in the clinical setting where patients present with injuries of varying types, severities, and comorbidities. Modeling this highly varied population in the laboratory remains challenging.
