Northeastern researcher Kim Lewis is spearheading an effort to accelerate discovery of new antibiotics as part of a multi-institutional, federally funded project to tackle the growing problem of antibiotic resistance. “It’s a big issue because we largely stopped introducing novel antibiotics about 50 years ago,” says Lewis, distinguished professor of biology and director of Northeastern’s...

Hazel Sive, the dean of the College of Science and professor of biology at Northeastern University, has edited “Xenopus: A Laboratory Manual,” a new textbook that presents “a comprehensive collection of experimental procedures for research using Xenopus,” according to the publisher’s webpage. Xenopus — a genus of African frog — make for versatile experiments, as...

A new study from a Northeastern-led collaboration, looking into the C. elegans worms’ interactions with their microbiome, found that the worms are willing to leave a bacterial food source when they’re exposed to one of their deadliest toxins and identified the driving neurological mechanism behind it.

Professor Penny Beuning, chair of the chemistry and chemical biology department; Elizabeth Mynatt, dean of the Khoury College of Computer Sciences; and Hazel Sive, dean of the College of Arts and Science, have all been named fellows of the American Association for the Advancement of Science.

After the microscopic roundworms he was studying survived a toxic chemical environment, professor Javier Apfeld was intrigued to discover their tactic for protection against chemical foe.

Caenorhabditis elegans, a transparent, microscopic worm, has evolved a way to take advantage of protection provided by nearby bacteria. This response could provide clues as to how humans coordinate our own cellular defense systems.
