Contact: Diana Kenney, Marine Biological Laboratory dkenney@mbl.edu; 508-289-7139 One of the surprising discoveries to emerge from the young field of comparative genomics is that drastically different organisms—humans, sea urchins, worms, flies —are endowed with a more or less common set of genes. Given a similar DNA blueprint, then, how do species develop such vast differences […]

Contact: Diana Kenney, Marine Biological Laboratory 508-289-7139; dkenney@mbl.edu WOODS HOLE, Mass.—How a brilliant-green sea slug manages to live for months at a time “feeding” on sunlight, like a plant, is clarified in a recent study published in The Biological Bulletin. The authors present the first direct evidence that the emerald green sea slug’s chromosomes have […]

anaphase; image shows histones and 3D tracks of growing microtubule ends color-coded by velocity.

The MBL brimmed with news and activity in 2014, its always busy pace quickened by joint events and new programs with its affiliate, the University of Chicago. Below are just a few of many scientific, educational, and institutional highlights from an exciting year of discovery and transition. As we look forward to 2015, it’s important […]

Contact: Diana Kenney, Marine Biological Laboratory 508-289-7139; dkenney@mbl.edu WOODS HOLE, Mass.—Since the first “catalog” of the normal bacterial makeup of the human body was published in 2012, numerous connections between illness and disturbances in the human microbiota have been found. This week, scientists report yet another: Cancerous tumors in the ascending colon (the part nearest […]

Workshop at MBL Explores Past, Present, and Future of Cell Biology

Fiddler on the Roof? Northern Extension of Fiddler Crabs’ Range May be Sign of Climate Change

  WOODS HOLE, Mass.—David Johnson was standing in a salt marsh on the northern Massachusetts coast when he saw a fiddler crab, Uca pugnax, nearly 50 miles north of its supposed natural range. The migration north of this charismatic crab with the big, waving claw may be yet another sign of climate change. Johnson, then […]

An EZ-Pass for Fish: How a Fast-Warming Arctic Affects Migration and Survival

sm-web-deegan.highres-copy

The Arctic grayling may look—well, just plain old gray, but for Linda Deegan it’s a “beautiful fish” for many reasons besides being tasty. The grayling is one of very few fish that spends its entire life, including the frigid winter, in Arctic Alaska. To solve the mystery of how they cope, Deegan, a senior scientist […]
