Weathering the storm: youth vulnerability and resilience during the climate crisis
Teens are experiencing an increase in the incidence of anxiety and depression. Climate change adds uncertainty. Dire predictions and unknown impacts contribute to teens' worldview, increasing concerns that add to their normal stressors and anxiety; and for some, this becomes overwhelming. Here, we present a new perspective on teen mental health education and the impact of learning about climate change. We conclude that a comprehensive education can integrate the facts of global climate change, along with the progress in climate mitigation together with mental health education.

Cards, cubes, and collaboration: a case study of the development of an educational board game
Games are a powerful tool for learning, offering unique benefits for student engagement, particularly when addressing complex or challenging topics. The general public’s understanding of how vaccines are made is limited and the general public is unaware of the comprehensive research, development, and safety measures that are inherent in vaccine development. As such, we created a new educational game to address this knowledge gap. This case study examines the development process of an educational board game designed to enhance public understanding of vaccine development. The game, titled N.O.V.E.L.—Newly Observed Variant of Extreme Lethality, was created using a modified Backward Design methodology to align gameplay with specific educational standards and learning objectives. Designed for 2–4 players aged 10 and up, the cooperative game challenges participants to conceptually research a novel pathogen, develop an effective vaccine prototype, conduct animal testing and clinical trials, and distribute the vaccine—all while managing the spread of the disease. This case study details the iterative design process, including research and consultation with vaccine development experts, game prototyping, playtesting, refinement, and production. A key focus was balancing educational content with engaging gameplay mechanics to ensure both learning effectiveness and player enjoyment. Additional considerations such as original art, graphic design, teacher resources, alignment to educational standards, and animated videos were integrated to support accessibility and engagement in a classroom setting. The findings from this development process highlight best practices for designing educational board games and offer insights into how game-based learning can be used to communicate complex scientific concepts.

Telling the Stories of Neuroscientific Discovery to Schoolchildren and the Public Can Make an Impact
Neuroscience research demands focused attention built upon a foundational knowledge that can encompass the full sweep of science and engineering including, among other disciplines, psychology, biology, chemistry, physics, and computer science. Neuroscience studies range from evolution of lifeforms to new innovations in computational modeling. Neuroscientists can look at the population-level behavior, activity of the human brain, or atomic-level resolution of essential molecules. And yet, within these depths of emerging knowledge, the neuroscience community has the capacity to share what we know with young people and the public at large. Even little actions of communicating science in a manner that is broadly accessible and fun can initiate that ripple effect that informs a young mind.

RNA-Seq Reveals Sex Differences in Gene Expression during Peripheral Neuropathic Inflammation and in Pain Relief from a COX-2 Inhibiting Theranostic Nanoemulsion
Given decades of neuroinflammatory pain research focused only on males, there is an urgent need to better understand neuroinflammatory pain in females. This, paired with the fact that currently there is no long-term effective treatment for neuropathic pain furthers the need to evaluate how neuropathic pain develops in both sexes and how it can be relieved. Here we show that chronic constriction injury of the sciatic nerve caused comparable levels of mechanical allodynia in both sexes. Using a COX-2 inhibiting theranostic nanoemulsion with increased drug loading, both sexes achieved similar reduction in mechanical hypersensitivity. Given that both sexes have improved pain behavior, we specifically explored differential gene expression between sexes in the dorsal root ganglia (DRG) during pain and relief. Total RNA from the DRG revealed a sexually dimorphic expression for injury and relief caused by COX-2 inhibition. Of note, both males and females experience increased expression of activating transcription factor 3 (Atf3), however, only the female DRG shows decreased expression following drug treatment. Alternatively, S100A8 and S100A9 expression appear to play a sex specific role in relief in males. The sex differences in RNA expression reveal that comparable behavior does not necessitate the same gene expression.

Behavioral and inflammatory sex differences revealed by celecoxib nanotherapeutic treatment of peripheral neuroinflammation
Neuropathic pain affects millions of people worldwide, yet the molecular mechanisms of how it develops and persists are poorly understood. Given that males have historically been utilized as the primary sex in preclinical studies, less is known about the female neuroinflammatory response to injury, formation of pain, or response to pain-relieving therapies. Macrophages contribute to the development of neuroinflammatory pain via the activation of their cyclooxygenase-2 (COX-2) enzyme, which leads to the production of prostaglandin E2 (PGE2). PGE2 activates nociception and influences additional leukocyte infiltration. Attenuation of COX-2 activity decreases inflammatory pain, most commonly achieved by nonsteroidal anti-inflammatory drugs (NSAIDs), yet NSAIDs are considered ineffective for neuropathic pain due to off target toxicity. Using chronic constriction injury of the rat sciatic nerve, we show that males and females exhibit quantitatively the same degree of mechanical allodynia post injury. Furthermore, a low-dose nanotherapeutic containing the NSAID celecoxib is phagocytosed by circulating monocytes that then naturally accumulate at sites of injury as macrophages. Using this nanotherapeutic, we show that treated males exhibit complete reversal of hypersensitivity, while the same dose of nanotherapeutic in females provides an attenuated relief. The difference in behavioral response to the nanotherapy is reflected in the reduction of infiltrating macrophages at the site of injury. The observations contained in this study reinforce the notion that female neuroinflammation is different than males.

Targeted cyclooxygenase-2 inhibiting nanomedicine results in pain-relief and differential expression of the RNA transcriptome in the dorsal root ganglia of injured male rats
Chronic constriction injury of the sciatic nerve in rats causes peripheral neuropathy leading to pain-like behaviors commonly seen in humans. Neuropathy is a leading cause of neuropathic pain, which involves a complex cellular and molecular response in the peripheral nervous system with interactions between neurons, glia, and infiltrating immune cells. In this study, we utilize a nonsteroidal anti-inflammatory drug -loaded nanoemulsion to deliver the cyclooxygenase-2 inhibitor, Celecoxib, directly to circulating monocytes following nerve injury, which provides long-lasting pain relief. However, it is not fully understood how cyclooxygenase-2 inhibition in a macrophage traveling to the site of injury impacts gene expression in the dorsal root ganglia. To elucidate aspects of the molecular mechanisms underlying pain-like behavior in chronic constriction injury, as well as subsequent pain relief with treatment, we employ RNAseq transcriptome profiling of the dorsal root ganglia associated with the injured sciatic nerve in rats. Using high throughput RNA sequencing in this way provides insight into the molecular mechanisms involved in this neuroinflammatory response. We compare the transcriptome from the dorsal root ganglias of the following study groups: chronic constriction injury animals administered with cyclooxygenase-2 inhibiting celecoxib-loaded nanoemulsion, chronic constriction injury animals administered with vehicle treatment, a drug-free nanoemulsion, and a group of naïve, unoperated and untreated rats. The results show an extensive differential expression of 115 genes. Using the protein annotation through evolutionary relationship classification system, we have revealed pain-related signaling pathways and underlying biological mechanisms involved in the neuroinflammatory response. Quantitative polymerase chain reaction validation confirms expression changes for several genes. This study shows that by directly inhibiting cyclooxygenase-2 activity in infiltrating macrophages at the injured sciatic nerve, there is an associated change in the transcriptome in the cell bodies of the dorsal root ganglia.

The Use of a Mobile Application to Teach Concussion-Related Health Knowledge
Sports-related concussions affect over 280,000 adolescents each year while the general public remains ill-informed about concussions, signs/symptoms, and treatments. Adolescents may be at an increased risk for experiencing adverse physiological and psychological effects from concussions, underscoring the critical need for effective concussion education strategies. While mobile apps are increasingly being used in education and healthcare settings, none were found to offer comprehensive concussion education capable of reaching diverse audiences. The interactive mobile app “Rebound: Beating Concussions” has the potential to be an effective teaching tool for school athletic programs and medical professionals to communicate important concussion-related information to student athletes, parents, and sports coaches. A mixed methods study was used to determine the app’s ability to convey information about concussions to student athletes in grades 5 through 12, parents of student athletes, and sports coaches. Concussion knowledge and participant opinions were assessed via a pre/post model and administered before and after app use. Participants demonstrated knowledge gains in the identification of concussion symptoms, treatments, and misconceptions. Additionally, participants demonstrated positive opinions on the content of the app, its relevance to everyday life, and its potential as a teaching tool.

Differential Expression of Neuroinflammatory mRNAs in the Rat Sciatic Nerve Following Chronic Constriction Injury and Pain-Relieving Nanoemulsion NSAID Delivery to Infiltrating Macrophages
The neuroinflammatory response to peripheral nerve injury is associated with chronic pain and significant changes in the molecular expression profiles of mRNAs in neurons, glia and infiltrating immune cells. Chronic constriction injury (CCI) of the rat sciatic nerve provides an opportunity to mimic neuropathic injury and quantitatively assess behavior and differential gene expression in individual animals. Previously, we have shown that a single intravenous injection of nanoemulsion containing celecoxib (0.24 mg/kg) reduces inflammation of the sciatic nerve and relieves pain-like behavior for up to 6 days. Here, we use this targeted therapy to explore the impact on mRNA expression changes in both pain and pain-relieved states. Sciatic nerve tissue recovered from CCI animals is used to evaluate the mRNA expression profiles utilizing quantitative PCR. We observe mRNA changes consistent with the reduced recruitment of macrophages evident by a reduction in chemokine and cytokine expression. Furthermore, genes associated with adhesion of macrophages, as well as changes in the neuronal and glial mRNAs are observed. Moreover, genes associated with neuropathic pain including Maob, Grin2b/NMDAR2b, TrpV3, IL-6, Cacna1b/Cav2.2, Itgam/Cd11b, Scn9a/Nav1.7, and Tac1 were all found to respond to the celecoxib loaded nanoemulsion during pain relief as compared to those animals that received drug-free vehicle. These results demonstrate that by targeting macrophage production of PGE2 at the site of injury, pain relief includes partial reversal of the gene expression profiles associated with chronic pain.
