1 in 25 carries a genotype that is associated with a shortened lifespan

A recent study published in the New England Journal of Medicine found that 4% of Icelanders carry an actionable genotype associated with increased risk of cardiovascular, cancer, and metabolic diseases. These genotypes can lead to a three-year shorter median survival for carriers, particularly those with cancer-predisposing variants.

‘Alien’ wasps thriving in tropical forests, study finds

Researchers discovered high biodiversity of Darwin wasps on a mountain in the Brazilian Atlantic Rainforest, with 98 species found. This finding debunks the notion that these wasps thrive only in cooler habitats and highlights the importance of protecting tropical environments.

Children's dental health significantly improved using electric toothbrushes

A new study found that electric toothbrushes significantly reduce plaque and gingivitis in young children aged 3-10. The research showed that electric toothbrushes are more effective than manual toothbrushes in reducing these dental issues, with whole mouth plaque reduction increasing by up to 55.7% in younger children.

Does cannabis use affect empathy?

Regular cannabis users show a greater understanding of others' emotions, while their brains exhibit stronger connections between regions related to emotional sensing. This study suggests potential therapeutic applications for conditions involving social interaction deficits.
