Antibiotic resistance directly kills more than a million people annually, while antibiotic discovery has stagnated. In 2025, a Penn AI screened 40.6 million peptide sequences generated from venom proteins in only hours, shortlisted 386 unusually novel candidates and successfully predicted antibacterial activity in 53 of the 58 subsequently tested in the laboratory.
1+ hour, 42+ min ago (1139+ words) Penn’s APEX model reduced 40.6 million generated venom-protein fragments to a novel shortlist. Laboratory tests validated 53 of 58 selected peptides, while toxicity and translation remain open problems.

Chemists Can Now Rewrite a Drug Molecule in a Single Step Instead of Building It From Scratch
2+ mon, 1+ week ago (573+ words) Using the new method for converting methylamines, complex compounds can be produced under simple conditions. Their target was a workhorse class of compounds called secondary N-methylamines, in which a nitrogen carries a single methyl group, a tiny CH₃ cap that turns…...
