In a study involving 440 students from northern Thailand boarding schools, 10.2% practiced this meditation technique. The average stress level was moderate at 24.08, while depression scores were low at 3.82. Notably, those engaging in death recollection showed fewer depressive symptoms, with a moderation effect indicating that this practice helps buffer the impact of stress on mental health. This suggests that integrating death meditation into mindfulness practices could benefit adolescents facing stress.
Abstract
Death recollection is a form of mindfulness meditation that orients a practitioner's calm attention toward an awareness of death. This meditation i...
In vitro metabolic fate of 1-[3-(trimethylsilyl)propanoyl] lysergic acid diethylamide (1S-LSD), a silicon-containing LSD analog.
Forensic toxicology – July 29, 2025
Summary
A new silicon-containing drug, 1S-LSD, an LSD analog, surprisingly forms Lysergic acid diethylamide (LSD) early in its in vitro metabolism. Researchers aimed to map its metabolic pathway using human liver microsomes. They identified 62 metabolites, proposing a detailed pathway. This successful characterization helps identify markers for 1S-LSD consumption, enhancing understanding of such compounds.

A new lysergic acid diethylamide (LSD) analog has recently been identified, 1-[3-(Trimethylsilyl)propanoyl] LSD (1S-LSD), characterized by a silico...
Examining the Dose-Response Effects of Mindfulness Meditation Interventions on Well-Being: Protocol for a Randomized Controlled Trial.
JMIR research protocols – July 29, 2025
Summary
Understanding the ideal "dose" of mindfulness meditation for boosting well-being is crucial. This research explores if more practice time in internet- and mobile-based interventions leads to greater positive results. Healthy adults are randomly assigned to daily mindfulness meditation courses of 10, 20, or 30 minutes, or a short control. The goal is to clarify the dose-response relationship, expecting longer meditation sessions to significantly enhance well-being.
Abstract
Mindfulness meditation has demonstrated modest benefits for mental health and well-being, although the relationship between practice dose and outco...
Psilocybin in the treatment of eating disorders: a systematic review of the literature and registered clinical trials
Eating and Weight Disorders - Studies on Anorexia Bulimia and Obesity – July 29, 2025
Summary
With Fluoxetine the only pharmacological treatment approved for Bulimia Nervosa, and no drugs for other eating disorders like Anorexia Nervosa, new options are crucial. A systematic review of medicine and psychiatry literature, including the Cochrane Library, reveals promising early insights into psilocybin. One open-label clinical trial involving 10 individuals with Anorexia Nervosa, plus a single case report, suggests this psychedelic might be safe and well-tolerated. Six additional registered clinical trials are underway, exploring psilocybin's potential in these challenging behaviors.
Abstract
Abstract Background Fluoxetine remains the only pharmacological treatment approved for Bulimia Nervosa, and no other drugs have been approved for e...
EEG Brain Rhythms During Resting-State Wakefulness and Sleep in Elderly Expert Meditators.
Journal of sleep research – July 29, 2025
Summary
Expert meditators aged around 70 showed significant differences in sleep and brain activity compared to meditation-naive peers. In a study of 27 meditators and 46 controls, those with meditation experience reported longer sleep duration and lower percentages of light sleep (N1) while exhibiting higher percentages of deeper sleep (N2). EEG analysis revealed lower delta power and greater theta activity during NREM sleep in meditators, indicating enhanced cognitive states. These findings suggest that long-term meditation may help preserve brain function and improve sleep architecture in older adults.
Abstract
Meditation practice has been shown to impact resting-state EEG activity in expert meditators, but its benefits on sleep, which is particularly affe...
Exploring Esketamine's Therapeutic Role for Perinatal Depression via TASK-1 Tandem Pore Potassium Channels.
ACS chemical neuroscience – July 29, 2025
Summary
Remarkably, a new approach significantly lowers depression scores in new mothers. It investigates how esketamine works, specifically targeting the TWIK-related acid-sensitive K+ channel 1 channel. Clinical trials with 298 women and lab studies confirmed its benefits. This treatment effectively combats perinatal depression by reducing neuroinflammation and enhancing synaptic plasticity, mediated by the TWIK-related acid-sensitive K+ channel 1 channel. This suggests esketamine is a powerful therapeutic avenue, offering a clear path to improved mental well-being.
Abstract
This research focuses on the promising use of esketamine in perinatal depression, a widespread disorder impacting postpartum women's mental health....
Discovery of Rapid-Acting, Orally Available Antidepressants by Activating TrkB Signaling.
Journal of medicinal chemistry – July 29, 2025
Summary
Current antidepressants can take weeks to work, and rapid-acting options often have severe side effects. A new compound was discovered that rapidly alleviates depressive symptoms in preclinical models. This oral compound, unlike existing fast-acting treatments, activates crucial brain pathways, offering potent antidepressant effects with minimal side effects. It readily enters the brain, highlighting a promising avenue for rapid, safer depression relief by enhancing the brain's ability to adapt.

Major depressive disorder (MDD) remains a significant global health burden, and its current treatments are limited by the delayed onset of efficacy...
Electrophysiological effects of psilocybin co-administered with midazolam
OpenAlex – July 29, 2025
Summary
Imagine experiencing a profound psychedelic journey without memory of it. A pilot study in **psychedelics and drug studies** gave participants 25 mg of psilocybin—an **alkaloid** from **chemical synthesis**—with a sedative. This allowed the full psychedelic experience, blunting recall. Brain activity showed distinct patterns: initially, increased beta power; then, as psilocybin's **neurotransmitter receptor influence on behavior** grew over six hours, increased brain complexity and altered power. Psilocybin's effects persist despite memory suppression, supporting mechanistic studies.
Abstract
Abstract The serotonergic psychedelic psilocybin induces neural plasticity and profoundly alters consciousness. The benzodiazepine midazolam blunts...
