Wealth inequality: Closing the gap by taxing land and bequests

A policy package of bequest taxes and land value taxes could reduce wealth inequality without diminishing economic performance. The study finds that these taxes have a strong advantage over corporate taxation, and can even help mitigate housing shortages.

Metagenomics of early childhood oral health and early childhood caries

Researchers analyzed preschool-age children's supragingival microbiomes to understand early childhood caries (ECC) development. Notable differences in bacterial species abundance were found among caries-free, restored disease, and untreated disease groups, suggesting that restorative care alone may not reverse ECC-associated dysbiosis.
