A thyroxine derivative enhances brain drug delivery

Researchers developed prodrugs that temporarily incorporate thyroxine or a thyroxine-like molecule to enhance brain drug delivery. These prodrugs were efficiently delivered into glial cells via the OATP1C1 transporter, targeting chronic inflammation in the brain.

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.
