Researchers used a microfluidic platform to screen the oral microbiome of Siberian brown bears and identified an antibiotic-producing strain of Bacillus pumilus that kills Staphylococcus aureus. The study also uncovered a mechanism by which Bacillus resists this antibiotic, suggesting its potential for discovering novel antibiotics.

A new study by NYU's Michael Hout finds that Americans' occupational status is strongly linked to their parents' occupation, with high-status parents' children having greater advantages in the labor force. The study uses median-based data and reveals stark distinctions between top and bottom tiers of occupation status.
