Genomes from 25 museum specimens of Drosophila melanogaster (some more than 200 years old) reveal that small populations occupying northern Europe gave way to well-connected fly populations across the continent

Recent study on Drosophila melanogaster museum specimens shows that Northern European populations gave way to well-connected fly populations across the continent. The analysis also highlights genes that may have helped this species adapt to novel climates, viruses, and insecticides.

Risk for dementia varies by ethnicity, study finds

A new study analyzing English primary care records found that hypertension, obesity, diabetes, and low HDL cholesterol confer a higher risk of dementia in South Asian and Black people compared to White individuals. The results suggest tailored dementia prevention efforts should be targeted towards minority ethnic groups.

Novel procedure reduces the risk of mitochondrial disease transmission

A novel procedure using a refined technique and narrower tube has reduced the risk of transmitting mitochondrial disease during assisted reproduction. The study found that the new protocol resulted in normal development of embryos and healthy offspring, with minimal transfer of maternal mitochondria to the offspring.

Despite denouncements, conversion practices remain prevalent for sexual and gender minority individuals - with estimates centering on 1 in 10 - and prevalence differences by country, race and sex assignment at birth

A systematic review found conversion practices affecting approximately 1 in 10 sexual and gender minority populations, with significant variations across countries, racial groups, and sex assignments. The study's results highlight the need for increased awareness and support for individuals experiencing these practices.

Being a vegetarian may be—partly—in your genes

A genome-wide association study reveals 34 genes potentially involved in choosing a vegetarian diet, including those related to lipid metabolism and brain function. The findings suggest that genetics play a role in the ability to subsist on a vegetarian diet.

Adoption of vegan dog and cat diets could have environmental benefits

A new analysis estimates that switching all pet dogs and cats to vegan diets could spare nearly 2 billion land-based livestock animals yearly in the US, and nearly 7 billion globally. This could lead to significant reductions in environmental impacts such as land use, water consumption, and greenhouse gas emissions.

Rural counties showing steeper decline in health measures compared to urban counties in 2015 versus 2019—though all areas showed declines in health measures over time

A recent study has found that rural US counties have worse health outcomes than their urban counterparts, with declines in health measures accelerating over time. The researchers developed a publicly available dashboard to visualize health disparities and identify areas for policy interventions.

Computer model predicts who needs lung cancer screening

A machine learning model developed by researchers can predict lung cancer risk with an 83.9% sensitivity, identifying those who need screening for the disease. The model uses just three predictors: age, smoking duration, and pack-years of smoking, making it a simplified approach to determine high-risk populations.

Interconnected factors increase household food insecurity in Brazil

A recent study found that households headed by single women of color in Brazil are four times more likely to experience food insecurity compared to those headed by married white men. The researchers argue that policies addressing gender equality, antiracism, and family considerations can help reduce poverty and hunger.

Training the gut’s immune system to combat detrimental effects of emulsifiers in processed food

Researchers found that training the gut's immune system to target flagellin, a protein enabling bacterial motility, protects against emulsifier-induced chronic intestinal inflammation and metabolic dysregulation. This study suggests a potential new approach for preventing inflammatory conditions such as obesity and type 2 diabetes.

During failure of core protein quality control in the nematode C. elegans, a specialized anti-aggregation mechanism relying on pathogen response factors and lysosomal mediated degradation is triggered

In C. elegans, a specialized anti-aggregation mechanism is triggered in response to core protein quality control failure, promoting tissue-specific resilience to age-dependent protein aggregation. This mechanism relies on pathogen response factors and lysosomal mediated degradation.

Europeans may be more willing to help Ukrainian refugees than those from Syria or Somalia in part because they consider Ukrainians less threatening

A study found Europeans are more willing to assist Ukrainian asylum seekers than Syrians or Somalis, largely because of the perceived lower threat level associated with Ukrainians. The research suggests that emotional factors and prejudice play a significant role in shaping attitudes towards helping refugees.

How bright-light treatment improves sleep in stressed mice

Researchers identified the neural pathway behind chronic stress-induced sleep disturbances and found that bright-light treatment counteracts these effects by targeting the lateral habenula. The study reveals a critical connection between the habenula and the rostromedial tegmental nucleus, which is essential for regulating non-REM sleep.
