A new study suggests that 8-year-old children's views about women mirror their parents' sexist attitudes, with fathers' hostile sexism and mothers' benevolent sexism being most consistently linked to their children's beliefs.

* 🧸 A 2023 study on 175 New Zealand family groups found that 8-year-olds' views on women often reflect their parents' sexist attitudes. Fathers' hostile sexism was linked to children's hostile views, while mothers' benevolent sexism was linked to children's benevolent views.

* 👨‍👩‍👧‍👦 The research, published in Sex Roles by authors Voznyuk, Overall, and Hammond, suggests distinct roles for mothers and fathers in transmitting these beliefs. Fathers' hostile sexism may lead to more controlling behavior, while mothers' benevolent sexism might involve actively teaching traditional gender roles.

* 🧠 The study highlights that children learn from parental attitudes and everyday interactions at home, with these learned beliefs potentially impacting future career opportunities and relationships. The authors emphasize this is not about blaming parents but recognizing the influence of learned beliefs.

A deep-sea mining test 1,300 m down in the South China Sea quickly messed up the seafloor's tiny microbes: genes that turn nitrogen into food for sea life dropped, while signs of low-oxygen conditions rose. Scientists warn even short mining trials can rapidly disrupt the deep ocean's nutrient cycle.

🔬 A new study in the South China Sea reveals deep-sea mining can significantly disrupt microbes essential for nutrient cycling. Samples collected during a 2020 trial at 1,300 meters showed changes in genes related to nitrogen processes and sulfate reduction.

💧 Mining operations stirred up sediment, altering nutrient availability in waters up to 50 meters above the seafloor, particularly impacting nitrogen and silicate levels.

📉 Genes for nitrogen fixation and nitrite reduction decreased, while denitrification genes increased, indicating immediate disruption to the seafloor's microbial ecosystem.

More than half of people with early-onset type 2 diabetes (average age just 38) went into remission with no meds after a 24-week program: 12 weeks of 800–900 calories a day plus supervised strength and cardio workouts. They lost fat but kept their muscle, and even their hearts became healthier, too.

✨ New research suggests type 2 diabetes may not be a lifelong diagnosis.
A combined low-calorie diet (800-900 kcal/day) and supervised exercise program (twice-weekly aerobic/resistance training) put over 50% of early-onset type 2 diabetes patients into remission in a 24-week trial involving 96 participants in Canada and the UK.

💪 Participants in the intervention group achieved remission in 27 out of 50 individuals, compared to only two in the control group. This intervention, led by Kaberi Dasgupta at McGill University, also improved cardiovascular health and preserved muscle mass.

🔬 The study, published in The Lancet Regional Health – Americas, highlights the potential of lifestyle changes for clinically meaningful remission and holistic health benefits, even in early-onset cases of diabetes, often diagnosed at 45 or younger.

AI scans of 100,000+ people found those with 'brown fat' had less diabetes, heart disease, anxiety and depression. People on blood pressure pills were more likely to have it, and in mice, the common drug losartan switched brown fat on, making it burn more energy and heat.

🔬 Rockefeller University researchers found that detectable brown fat is linked to a lower likelihood of type 2 diabetes, heart disease, anxiety, and depression in a study of 101,243 participants.

💊 The study also suggests a potential medication: the blood pressure drug losartan was associated with a greater chance of having detectable brown fat. Mouse models showed losartan made brown fat more active.

💡 Scientists used AI to analyze medical records, identifying nearly 8,900 participants with brown fat and comparing them to controls.

A single dose of psilocybin eased depression within days, but its edge over placebo faded within a year. The effects appeared as early as the second day after dosing and lasted for more than three months, although by one year the difference between groups had faded.

Exclusive breastfeeding for six months linked to fewer ADHD symptoms in children. Research indicates that this protective effect holds up even when accounting for a child’s genetic predisposition to the condition.

✨ A 25-mg dose of psilocybin showed rapid antidepressant effects in a Swedish trial, appearing by day 2 and lasting over three months based on self-reports.

⏳ While initial clinician-rated effects lasted for weeks, the difference between psilocybin and placebo faded by one year.

📊 At 42 days, 53% of psilocybin recipients achieved remission compared to 6% in the placebo group.

💊 Psilocybin was generally well-tolerated with temporary side effects, though two participants experienced prolonged severe anxiety. Blinding proved largely ineffective.

🍼 Infants exclusively breastfed for the first six months showed fewer ADHD symptoms in childhood, even when accounting for genetic predispositions.

🧬 This protective effect was observed across thousands of Norwegian families studied from pregnancy through childhood, with each additional month of full breastfeeding linked to a measurable reduction in ADHD symptoms at ages three, five, and eight.

👨‍👩‍👧 Even when comparing siblings, the child who received exclusive breastfeeding for a longer duration tended to have fewer ADHD symptoms than their sibling who received less breast milk, suggesting a potential direct influence of breastfeeding.

Australian study tracked 6,500 symptom-free 12-year-olds for 3 years: each extra daily serve of fruit was linked to 13% lower risk of getting depression and 7% lower risk of anxiety, while teens drinking more soft drinks and other sugary drinks were much more likely to develop both, especially boys.

A simple blood test may spot Crohn's and ulcerative colitis up to 10 years before diagnosis. Scientists studied 2,000 blood samples and found people who later got bowel disease had distinct antibody patterns, including more antibodies to the glandular fever virus, years before any symptoms shows.

🔬 Research indicates that specific antibody patterns in blood could predict the onset of Inflammatory Bowel Disease (IBD) up to 10 years before diagnosis, offering hope for earlier detection and potential prevention.

🔬 Scientists at the University Medical Centre Groningen and Icahn School of Medicine at Mount Sinai identified immune system warning signs that appear years before symptoms of Crohn's disease and ulcerative colitis manifest.

🔬 Analysis of blood samples from US military personnel revealed distinct antibody patterns, including those against Epstein-Barr virus (for Crohn's) and the body's own proteins (for ulcerative colitis), a decade before diagnosis.

A clinical trial has found that hydrodissection, injecting saline to separate a trapped nerve from surrounding tissue, provides carpal tunnel relief lasting up to 6 months, outperforming standard steroid injections.

#CarpalTunnel #Hydrodissection #NerveRelief

✨ New research suggests injecting saline around a trapped nerve at the wrist could offer longer-lasting relief for carpal tunnel syndrome than steroid injections.

💧 A procedure called hydrodissection, using ultrasound to guide saline injection, separated tissues restricting the nerve. This relief lasted for six months in a small trial, significantly longer than steroid injections alone.

🔬 The trial involved 39 adults (63 wrists) and found that saline-only hydrodissection reduced nerve swelling and improved symptoms. Adding steroids to the procedure did not significantly improve outcomes compared to saline alone.

✅ This treatment, taking about 15 minutes with no hospital stay and minimal side effects, may be beneficial for mild to moderate carpal tunnel syndrome, though severe cases might still require surgery.
