    ## Short Segments Just seven days of meditation can rewire your brain, according to new research. An intensive meditation retreat has been shown to trigger significant changes in brain function and body chemistry, comparable to those seen with psychedelic experiences. Coming up, we'll explore how birth control trends might be influencing abortion rates, and why frequent cannabis users may face unexpected stress hormone levels. Scientists say just 7 days of meditation can rewire your brain. Researchers at the University of California, San Diego, have found that a week-long intensive meditation retreat can lead to profound changes in the brain and body. Participants experienced shifts in neuroplasticity, improved immune function, and increased natural pain relief. These changes were so significant that they mirrored the effects of psychedelic substances, suggesting that meditation could offer a drug-free path to altered states of consciousness. The findings highlight meditation's potential as a powerful tool for mental and physical health, offering new avenues for stress relief and resilience. Can birth control trends explain the rise in abortions? It's complicated. Following the Supreme Court's decision to overturn Roe v. Wade, there has been a noticeable shift in birth control usage. More individuals are opting for long-acting or permanent contraceptive methods. Despite these changes, the number of abortions in the U.S. has increased, reaching over one million in 2023. This rise occurs even as some states impose stricter abortion laws. The complex interplay between birth control choices and abortion rates suggests that other factors, such as access to telehealth services and cross-state travel for abortion care, may also be influencing these trends. Frequent cannabis users wake up with their “stress hormone” already elevated. Research from Oregon State University indicates that regular cannabis users may start their day with higher levels of cortisol, the body's primary stress hormone. This finding suggests that frequent cannabis use could disrupt normal stress rhythms, potentially undermining the body's ability to manage stress effectively. While many use cannabis for stress relief, this study raises questions about its long-term impact on stress regulation. Understanding these effects is crucial as cannabis use becomes more widespread, highlighting the need for further research into its physiological impacts. ## Feature Story What explains abortions going up despite stricter laws in many states? In a surprising trend, the number of abortions in the U.S. has increased, even as many states have enacted stricter abortion laws. According to the Guttmacher Institute, more than one million abortions were recorded in 2023, the highest in a decade. This rise comes after the Supreme Court's decision to overturn Roe v. Wade, which led to increased restrictions in several states. Despite expectations that abortion rates would decline, the opposite has occurred, with the country's fertility rate hitting a historic low. One factor contributing to this trend is the increased use of telehealth services, allowing individuals in states with total bans to access abortion care remotely. Additionally, many are traveling across state lines to obtain the procedure. These shifts in access have maintained, and even increased, abortion rates despite legal restrictions. Another layer to this complex issue is the changing landscape of birth control. While more people are opting for long-acting contraceptives, the overall impact on abortion rates remains unclear. The interplay between these factors suggests that access to abortion services is adapting to new legal realities, rather than diminishing. As these dynamics continue to evolve, monitoring the impact on public health and reproductive rights will be essential.

    ## Short Segments Teen cannabis use is linked to slower memory and thinking growth, according to new research from the University of California, San Diego. Today, we'll explore how cannabis affects adolescent brain development, and later, we'll dive into the implications of federal funding restrictions on test strips for drug users. Researchers have found that teenagers who begin using cannabis may experience slower growth in cognitive abilities such as memory, attention, language, and processing speed. The study, published in Neuropsychopharmacology, analyzed data from over 11,000 participants in the Adolescent Brain Cognitive Development Study, the largest long-term study of brain development in U.S. youth. While these abilities often develop normally at first, they tend to level off in cannabis users, whereas non-users continue to improve. THC, the psychoactive component of cannabis, appears to be the most likely driver of these changes, particularly affecting memory. This research highlights the critical period of adolescence for brain development and suggests that cannabis use during these years could have lasting impacts on cognitive growth. As cannabis becomes more accessible, understanding its effects on young brains is crucial for parents, educators, and policymakers. ## Feature Story Federal funds can no longer be used to provide test strips to drug users, raising concerns about increased overdose risks. The Trump administration's decision to restrict the use of federal funds for fentanyl test strips marks a significant shift away from harm reduction strategies. Test strips are a critical tool for identifying dangerous additives in street drugs, such as fentanyl, which can significantly increase the risk of overdose. Public health groups and local health departments have relied on these strips to help prevent fatal overdoses, especially in areas with high rates of drug use. In Baltimore, for example, three mass overdose incidents occurred within three months in the Penn North neighborhood. In one incident, more than two dozen people were hospitalized after being found unresponsive. Follow-up testing revealed that the street drugs involved contained dangerous contaminants. The Substance Abuse and Mental Health Services Administration (SAMHSA) issued an open letter in April, ordering an end to the use of its funding for all substance testing strips, including those for fentanyl, xylazine, and medetomidine. This decision has baffled public health organizations, who warn that it could reverse progress made in combating fatal overdoses. Critics argue that the move could have fatal consequences, as it removes a key tool for harm reduction. Without federal funding, local health departments and nonprofits may struggle to provide these test strips to those who need them most. As the opioid crisis continues to evolve, the need for effective harm reduction strategies remains critical. The decision to restrict funding for test strips could hinder efforts to prevent overdoses and save lives. Looking ahead, public health advocates are calling for a reevaluation of this policy, emphasizing the importance of harm reduction in addressing the ongoing drug crisis. The debate over federal funding for test strips highlights the broader challenges in balancing public health priorities with policy decisions. As the situation develops, stakeholders will be watching closely to see how this policy change impacts overdose rates and public health efforts across the country.

    ## Short Segments Today, a wearable ultrasound patch promises to enhance REM sleep without drugs or surgery, a new autism therapy shows benefits even in adult mice, and the debate over hormone therapy for menopause continues. We'll also explore the variability in reimbursement rates for state-funded abortion services, and a study unpacks the triangle of income, mental health, and physical health. Later, we'll dive into a promising new vaccine that could combat a major cause of deadly diarrheal disease. Wearable ultrasound patch boosts REM sleep without drugs or surgery. A new wearable patch may help people reach REM sleep faster and stay there longer, without the need for medication or surgery. In a study involving 28 participants, the device reduced the time to reach REM sleep by 43 minutes and extended the duration by about 16 minutes. Researchers also noted improvements in stress regulation and changes in brain circuits related to emotion. This noninvasive technology, developed by a team at the University of Texas at Austin, uses gentle ultrasound waves to stimulate deep brain regions and monitor brain activity in real time. The findings suggest a potential breakthrough in sleep management, offering a drug-free alternative for enhancing sleep quality. New autism therapy shows surprising benefits even in adult mice. A novel therapy targeting the glycine transporter SLC6A20 has shown promising results in autism-related mouse models. By blocking this transporter, researchers restored crucial brain signaling and improved social, communication, and repetitive behaviors. The treatment also demonstrated effectiveness in human brain organoids and had lasting effects in adult mice, indicating that the brain may remain more treatable later in life than previously thought. This approach shifts focus from traditional, often toxic, systemic targets to more precise molecular mechanisms, offering hope for new therapeutic strategies in autism spectrum disorder. Everyone's talking about hormone therapy for menopause. Should I be on it? Hormone therapy for menopause is gaining attention as a potential solution for symptoms like hot flashes and vaginal discomfort. However, it's important to weigh the benefits against the risks, which can vary depending on individual health factors. While some see it as a wonder drug, others caution against its use without thorough consultation with healthcare providers. The resurgence of interest in hormone therapy highlights the need for personalized medical advice and careful consideration of the potential impacts on long-term health. Variability in reimbursement rates for state-funded abortion services for Medicaid enrollees: A 2026 update. A recent analysis by KFF reveals significant variability in how states reimburse abortion services for Medicaid enrollees using state funds. Twenty-one states currently use their own funds to cover abortion services beyond the federal Hyde Amendment's restrictions. This variability can affect access to abortion care, highlighting the ongoing challenges in ensuring equitable healthcare coverage across different states. The findings underscore the complex landscape of abortion funding and the need for consistent policies to support Medicaid enrollees. The income, mental health, and physical health triangle, unpacked. A new Danish cohort study explores the interconnectedness of income, mental health, and physical health. The research highlights how these factors influence each other, forming a triangle of mutual impact. Higher income is generally associated with better health outcomes, but mental illness can shorten life expectancy through common physical conditions. Understanding these relationships is crucial for developing policies that address health disparities and improve overall well-being. The study provides a comprehensive look at how socioeconomic factors shape health outcomes, offering insights for future interventions. [Translated] Vitamin C may fight cancer — but not the way scientists once thought. Intravenous vitamin C is gaining attention for its potential role in cancer treatment. Unlike oral supplements, high-dose intravenous vitamin C can reach concentrations that act more like an experimental cancer drug. Early studies suggest it may damage vulnerable cancer cells, reduce treatment side effects, and improve outcomes for some patients. While promising, this approach remains investigational, and larger randomized trials are needed to confirm its efficacy and safety. The evolving understanding of vitamin C's role in cancer therapy reflects the complexity of developing effective treatments. ## Feature Story A new vaccine could vanquish a major cause of deadly diarrheal disease. Diarrheal diseases claim over 1 million lives annually, with nearly half of the victims being children under five.
