New study finds that the brain's energy system rapidly recovers in alcoholics just a few weeks after they stop drinking
A new study found that psychiatrists agree on a diagnosis in only 55% of cases, raising concerns about misdiagnosis and treatment errors. The study's results also suggest that diagnostic categories are not as clearly defined as assumed, leading to disagreement among clinicians.
Girls born to mothers who took acetaminophen (paracetamol) during pregnancy exhibited smaller uteri (−13%) & ovaries (−40%), fewer ovarian follicles (−23%), and lower levels of anti-Müllerian hormone, which could affect fertility later in life. This replicates an outcome observed in animal studies.
In Ontario, Canada, national identity among white working-class voters has a strong association with the center-left Liberal Party and no association with racial resentment, religiosity and anti-government sentiment. This stands in contrast to similar voters across the border in the US Midwest.
Endocannabinoids produced by the body may contribute to the \"runner's high\": the happiness, calm, reduced anxiety, and dulled pain some people experience during long runs. This feeling was once credited to endorphins, but they do not readily cross the barrier between the blood and brain.
GLP-1 drugs may improve obstructive sleep apnea through mechanisms beyond weight loss, including effects on breathing control, upper-airway neuromuscular function, and inflammation
A study of 4,884 men with nonmetastatic prostate cancer found those consuming the most saturated fat after diagnosis had a 24% higher risk of death, while replacing animal fats with plant-based fats was associated with a 16% lower risk of death.
Across 134 countries and territories, an estimated 45%–55% of governments misreported Covid mortality, with underreporting far more common than overreporting. The study provides comparable country-level data of the extent of misinformation for researchers and policymakers
Horse personality is not only a matter of genetics, age, or breed but also systematically linked to how they are housed, ridden, and cared for, and to the quality of the horse–owner relationship. Findings underscore the importance of everyday management decisions for equine personality and welfare.
New research shows that gentle \"pink noise\" delivered during sleep boosts slow brain waves, accelerating the fluid flow that washes away toxic waste and potentially leading to more restorative sleep.
A new study finds India’s income and wealth inequality has surged since the 1980s, accelerating after 2000. By 2022–23, the top 1% received 23.3% of national income and owned 40.1% of wealth, the highest levels since 1922.
A study of over 40,000 people receiving methadone treatment for opioid use disorder found take-home dosing was associated with lower mortality and treatment discontinuation than no take-home dosing, with the greatest benefits when initiated within 5 to 24 weeks after induction.
A four-year study of over 1,200 adults in 50 rural Chinese villages found that switching household heating from coal to electricity or natural gas under China’s Clean Heating Policy reduced indoor air pollution and was associated with lower blood pressure.
Harvard study predicts most suicide attempts a week in advance. Research led by psychologist Matthew Nock forecasts 75 percent of suicide attempts and 87 percent of suicide-related crises before they occurred — a marked leap beyond existing prediction models
Modelling over 16,000 groundwater samples, researchers found wells near land vulnerable to shale gas spills were three times more likely to carry deep drilling fluid chemicals.
Microscopic evidence reveals crocodile-like strategy kept the eggs of the largest dinosaurs warm | Titanosaur eggshells from the latest Cretaceous of Patagonia, Argentina: implications for nesting at high latitude
Systematic review of 155 studies finds updated COVID-19 vaccines provide meaningful protection against hospitalization and death, especially in older adults. Effectiveness against hospitalization was ~35–59% in adults ≥65. Protection varies by variant, age and time since vaccination.
In mice, researchers found evidence that Alzheimer’s disease may originate outside the brain, with signals from other organs helping drive the neurodegenerative changes linked to memory loss and cognitive decline.
Subglacial geology and thermal conditions regulate methane emissions from Svalbard glaciers
Longer periods of air pollution exposure can stress the heart, with just three hours at low pollution levels linked to a significant decline in heart rate variability, a sign of increasing physiological stress
