Biologists find a hidden weak spot in how bacteria build the tails they use to move

New research from Indiana University has uncovered a previously unknown vulnerability in how bacteria build the whip-like tails they use to move. The researchers found that building these tails can put stress on the protective ...

Tiny molecular rings open new ways for designing better medicines

Cyclopropanes are organic chemistry's smallest rings. Three carbon atoms are joined in a triangle, creating a compact and unusually strained structure. Despite—or partly because of—this unusual geometry, cyclopropanes are ...

A crystalline sponge reveals structures of large 'beyond rule of 5' molecules

Drug discovery has traditionally followed the "rule of 5," which identifies chemical properties generally associated with good absorption of orally administered drugs, including a molecular weight below 500 daltons (Da). ...

New way to harness copper makes antibiotic-resistant bacteria and cancer cells more vulnerable

University of Missouri researchers have discovered a new way to harness one of the body's natural defenses: copper. While copper is essential for life and helps power important biological processes, having too much of it ...

Changing the antibiotic playbook to catch an ESKAPE artist

Nearly a century ago, a single colony of Staphylococcus aureus (S. aureus) helped launch the antibiotic age. In 1928, Alexander Fleming returned to his London lab to find that a stray mold had wiped out the Staphylococcus ...
