Contact: Diana Kenney, Marine Biological Laboratory 508-289-7139; dkenney@mbl.edu WOODS HOLE, Mass.—In a blind fish that dwells in deep, dark Mexican caves, scientists have found evidence for a long-debated mechanism of evolutionary change that is distinct from natural selection of spontaneously arising mutations, as reported this week in the journal Science. The eyeless cavefish Astyanas mexicanus […]

Printable version (pdf) Contact: Gina Hebert 508-289-7725; ghebert@mbl.edu WOODS HOLE, MA—The vast sagebrush landscapes of the western United States are one of the largest ecosystems in North America.  Long, cold winters and hot, dry summers characterize these cold desert ecosystems and create bone-dry soils during seasonal droughts. New research published this week from MBL (Marine […]

Mechanisms of Wound Healing are Clarified in Zebrafish Study

WOODS HOLE, Mass.— A crucial component of wound healing in many animals, including humans, is the migration of nearby skin cells toward the center of the wound. These cells fill the wound in and help prevent infection while new skin cells regenerate. How do these neighboring skin cells know which way to migrate? What directional […]

Contact: Diana Kenney, Marine Biological Laboratory 508-289-7139; dkenney@mbl.edu MBL, WOODS HOLE, Mass.—Jellyfish may not be fast, but they are one of the most efficient propulsors on the planet—which is why they can “bloom” and overrun an ecosystem by outcompeting much swifter predators like fish, Marine Biological Laboratory (MBL) visiting scientists report this week. “It seems […]

Brown-MBL student Cassandra Bilogan successfully defended her PhD dissertation last August at Brown University. She conducted her doctoral research in the lab of MBL Associate Scientist Marko Horb, making her the first Brown-MBL student to complete her degree in the Eugene Bell Center for Regenerative Biology and Tissue Engineering. Bilogan was enrolled in the Department […]
