A new study reveals a 1250% increase in Google searches for microdosing from 2015 to 2023, driven by relaxed regulations on cannabis and psychedelics. The research shows policy changes correlate with growing interest in microdosing, filling gaps in understanding substance use trends.
Researchers developed a novel peptide, KS-133, to target cognitive dysfunction in schizophrenia. By using a brain-targeting peptide, KS-487, they successfully transported KS-133 across the blood-brain barrier. Their nanoparticle-based drug delivery system improved cognitive functions in mice, offering a new therapeutic strategy.
New research shows people are more likely to accuse others of lying when AI makes the accusation first. This insight highlights the potential social impact of AI in lie detection and suggests caution for policymakers. The study found AI's presence increased accusation rates and influenced behavior, despite people's general reluctance to use AI lie detection tools.
A new study reveals how depression affects brain activity in the basolateral amygdala (BLA) of rats. Using a microelectrode array, researchers found increased theta frequency activity in the BLA correlated with depressive behaviors. These findings could pave the way for targeted treatments for depression. The research highlights the potential of specific brain activity as a biomarker for depression.
A new study uncovers the different patterns and reasons behind procrastination using a mathematical framework. It shows that procrastination is influenced by factors like immediate rewards and uncertainty about future outcomes. These insights can help develop personalized strategies to combat procrastination and improve productivity. The research also highlights the importance of understanding individual procrastination behaviors.
Empathetic children aged 7-9 show poorer health and higher inflammation levels when exposed to interparental conflict. The research highlights the physiological impact of empathy in stressful home environments. The findings suggest a need for educational programs to help empathetic children set boundaries. This could improve their long-term health outcomes.
Researchers developed three new MDMA variants (ODMA, TDMA, and SeDMA) that retain the therapeutic benefits while reducing side effects. These compounds affect mood-regulating brain structures similarly to MDMA but have fewer toxic breakdown products and lower interaction with serotonin receptors. The study suggests these variants could make psychotherapeutic use of MDMA safer. Further research is needed to confirm their efficacy and safety.
Researchers found that people over 50 with anxiety have twice the risk of developing Parkinson’s disease. Using UK primary care data from 2008-2018, the study compared 109,435 patients with anxiety to 878,256 without. Results showed increased Parkinson’s risk and identified additional risk factors like depression and sleep problems. This research suggests early detection and treatment for Parkinson’s might be possible by monitoring anxiety and related symptoms.
People struggle to distinguish between human and AI-generated voices, identifying them correctly only about half the time. Despite this, brain scans revealed different neural responses to human and AI voices, with human voices triggering areas related to memory and empathy, while AI voices activated regions for error detection and attention regulation. These findings highlight both the challenges and potential of advanced AI voice technology. Further research will explore how personality traits affect the ability to discern voice origins.
A new study reveals that mindfulness helps improve sleep quality and reduce stress by focusing on the present and minimizing negative thoughts. The study tracked 144 nurses over two weeks, highlighting how mindfulness influences emotion regulation and overall well-being. These findings offer valuable insights for employers aiming to reduce work-related stress. Future research will further explore effective stress-reduction strategies across various occupations.
