🎶 Popular music has become less explicit about emotions and relationships over time, both across generations and within artists' careers.

📊 A study analyzing 38,467 songs from 1947 to 2024 found lyrics are less emotional and socially focused, with increased anxiety-related language and declining sadness.

🤔 Contrary to expectations, artists' lyrics didn't become more positive or relational with age; instead, positive emotions and social references declined, suggesting external artistic, cultural, or industry forces at play.

🗿 New research on China's 2,200-year-old Terracotta Army suggests the sculptors included not only adult men but also women and children.

🗿 Analysis of 79 fingerprints found on 36 warrior statues indicates that 45% were likely made by adult men, 32.7% by adult women, and 22.3% by children under 15.

🗿 These findings challenge the long-held assumption of an exclusively adult male workforce, providing quantitative biological evidence for a diverse group of artisans involved in the monumental project.

Having health insurance in America doesn't mean you can actually use it. Researchers posing as patients called 5,822 in-network mental health providers: most calls hit voicemails, over half the listings were wrong, and just 24% of real calls ended with an appointment.

🩺 Study found that even with commercial insurance, getting a mental health appointment is difficult for Americans. Researchers acted as "secret shoppers" and called 5,822 providers, only securing an appointment 24% of the time.

📞 Of the calls where a person was reached (2,252 calls), 56% showed inaccurate provider directory information. An additional 22% of calls failed to result in an appointment due to capacity issues like providers not accepting new patients.

⏳ Callers faced an average wait time of 20.5 days for care, with longer waits for psychiatry compared to psychology.

According to a new study, public support in the US for restricting transgender restroom access rose from 54% in 2016 to roughly 62% in 2022, driven by a shift where conflicted individuals increasingly prioritized perceived safety risks over concerns about discrimination.

• 📊 Public opinion in the U.S. has become more conservative on transgender restroom access, with support for restrictive policies rising from 54% in 2016 to 62% in 2022.

• ⚖️ A study in Politics, Groups, and Identities found that conflicted individuals who believed both in security risks and discrimination are now more likely to favor restrictions, flipping from 62% opposing restrictions in 2016 to only 29% in 2022.

• 👶 The belief that transgender restroom access poses a security risk to women and children has strengthened, while concerns about discrimination against transgender individuals also grew slightly.

A new study has revealed that weight loss and diabetes medications like liraglutide alter how the body manages fluids by disrupting chemical signals between the brain and kidneys.

#WeightLoss #DiabetesMedications #BrainKidneyConnection

💧 New study reveals that diabetes and obesity drugs like liraglutide directly lower a key water-conserving hormone, disrupting brain signals to the kidneys. Findings were published in Science Advances.

🧠 The drugs mimic a natural hormone, making people feel full and prompting insulin release. Doctors observed patients losing water and sodium, with nausea and diarrhea as common side effects leading to dehydration.

🔬 Researchers found liraglutide acutely reduced arginine vasopressin (a water-conserving hormone) in human blood samples and decreased stored hormone in rat pituitary glands, suggesting a disruption in fluid balance regulation.

🔬 Further experiments showed these drugs also dampen the kidney's ability to retain water by affecting water channels.

A new study in mice reveals that alcohol triggers immune cells called microglia to dismantle the brain's extracellular matrix, a structural support system for brain cells, which directly leads to loss of synapses and cognitive impairment.

🧠 New research reveals alcohol damages the brain not just by affecting neurons, but by activating immune cells called microglia, which then dismantle the brain's structural support.

🔬 Scientists observed in mice that alcohol causes microglia to break down the extracellular matrix, weakening brain cell support and leading to synaptic loss and dysfunction, even before peak sedation.

🛡️ Disabling a protein called MyD88 in microglia significantly reduced alcohol-induced brain damage, synapse loss, and sedation in mice, highlighting a key pathway for potential therapeutic intervention.

🌍 Analysis of human brain tissue from individuals with alcohol use disorder showed similar signs of extracellular matrix disruption, suggesting this microglial-driven damage mechanism may occur in humans.

A new blind spot in AI research uncovered: ‘Autonomous AI scientists’ can use hidden data manipulation, benchmark bias, and automated p-hacking. Because these critical flaws vanish entirely in the final paper, traditional peer review can’t catch them—exposing deep risks for science.

For the first time ever, scientists comprehensively mapped all glaciers in the lower 48 US states. They found 1/4 disappeared and total area/volume shrank by 35% (195.29 km², 5.53 gigatons of ice) since the mid-20th century—reducing vital water runoff alpine ecosystems rely on to buffer droughts.

Young adults with higher social anxiety show stronger brain responses when others’ gaze conflicts with their apparent thoughts or feelings, but they were no better at explicitly judging what someone’s gaze meant. They were neither more accurate nor faster than participants with lower social anxiety

Smart women at work get treated worse by their own teammates. In two studies (432 students, 394 office workers), women who scored higher on intelligence tests were seen as more hostile, got less help and faced more mistreatment. Smart men didn't face this, and in one group were even treated better.

👩‍🏫 High-scoring women in cognitive ability tests are perceived as more hostile by teammates, leading to reports of more mistreatment and less help compared to men with similar scores.

💡 This pattern, studied by researchers including Nitya Chawla of the Carlson School of Management, suggests gender stereotypes influence colleague interactions, where women displaying high competence might be seen as lacking warmth.

🤝 Two studies, one with 432 business students and another with 394 financial employees in China, found that higher cognitive ability in women correlated with being seen as more hostile and less communal, resulting in less help and more victimization.

🏢 In contrast, men with higher cognitive ability in the corporate study were viewed as less hostile, receiving more help and experiencing less victimization.

A Drug Commonly Used to Treat Erectile Dysfunction, May Also Help Regenerate Damaged Muscle. Research Suggests the Medication, Tadalafil Could Support Muscle Repair and Recovery by Influencing Biological Processes Involved in Muscle Regeneration in Mouse Models.

#Tadalafil #MuscleRegeneration #BiomedicalResearch

🔬 New research from the University of Rome Foro Italico suggests the drug tadalafil, currently used for erectile dysfunction and pulmonary arterial hypertension, may boost tissue regeneration and repair in muscles by increasing muscle precursor cells and reducing cell death.

🧪 Lab tests on mouse muscle precursor cells showed tadalafil treatment significantly increased cell proliferation and survival. When cells were "scratched," they closed up faster with the drug applied, indicating improved regenerative capacity.

🤔 Interestingly, tadalafil-treated cells showed delayed maturation into muscle fibers, which researchers interpret as creating a larger reserve of muscle stem cells for future use. Further studies are needed to understand the long-term effects on muscle building.

⚠️ Researchers also note tadalafil's potential for misuse as a performance-enhancing drug in sports, prompting concerns for anti-doping agencies.

A survey of 15,000 people across 81 countries found that bottled water consumption persists despite awareness of microplastics. Convenience, marketing and concerns about access to safe drinking water influence consumption habits, suggesting that awareness alone is insufficient to change behavior.
