With modification a PARP inhibitor drug that's struggled in clinical trials kills cancer much more effectively, researchers say.

One enzyme may determine whether human development starts correctly. The discovery could help explain why some fertilization fails.

New research shows how a once-forgotten cellular structure fights in the "world’s oldest war," the battle between bacteria and viruses.

"...we really need new structural classes of antibiotics that have never been contaminated by clinical resistance from established antibiotic classes."

"We were surprised by the dramatic differences between the old mice that received the eNAMPT of young mice and old mice that received saline as a control."
