Antibiotics may have a new teammate in the fight against drug-resistant infections.
Researchers have engineered nanoparticles to produce chemicals that render bacteria more vulnerable to antibiotics. These quantum dots, described online October 4 in Science Advances, could help combat pathogens that have developed resistance to antibiotics (SN: 10/15/16, p. 11).
“Various superbugs are evolving too rapidly to be counteracted by traditional drugs,” says Zhengtao Deng, a chemist at Nanjing University in China not involved in the...
Breast cancer cells spread in an already-armed mob
COLD SPRING HARBOR, N.Y. — When breast cancer spreads, it moves in gangs of ready-to-rumble tumor cells, a small genetic study suggests. Most of the mutations that drive recurrent tumors when they pop up elsewhere in the body were present in the original tumor, geneticist Elaine Mardis reported May 9 at the Biology of Genomes meeting.
