FOR IMMEDIATE RELEASE Contact: Diana Kenney, Marine Biological Laboratory dkenney@mbl.edu; 508-289-7139 Written by Kelsey Calhoun WOODS HOLE, Mass.—Sleep seems simple enough, a state of rest and restoration that almost every vertebrate creature must enter regularly in order to survive. But the brain responds differently to stimuli when asleep than when awake, and it is not […]

Contact: Diana Kenney, Marine Biological Laboratory dkenney@mbl.edu; 508-389-7139 WOODS HOLE, Mass., and PROVIDENCE, R.I.—By mounting cameras and spectral sensors over a forest canopy in central Massachusetts, scientists have developed an innovative system to measure plant photosynthesis over large areas, such as acres of crops or trees, using information on solar-induced fluorescence in the leaves. The […]

MBL Announces Recipients of the 2015 Whitman Center Investigators at the MBL Research Awards

WOODS HOLE, MA—The Marine Biological Laboratory (MBL) has announced the recipients of its 2015 Whitman Center Investigators at the MBL Research Awards. Each year, this program supports approximately 20 scientists from U.S. and international institutions who come to the MBL for six or more weeks in the summer to conduct independent research. Funds for the […]

Contact: Diana Kenney, Marine Biological Laboratory 508-289-7139; dkenney@mbl.edu Parkinson’s disease is a slow-progressing neurodegenerative disorder that afflicts about 4 to 6 million people worldwide, most of them over the age of 50. Its major symptoms are problems with movement: shakiness, slowness, rigidity, imbalance, and difficulty walking. There is no known cure. The causes of Parkinson’s […]

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 […]

FOR IMMEDIATE RELEASE Contact: Diana Kenney, Marine Biological Laboratory 508-685-3525 (cell); 508-289-7139; dkenney@mbl.edu WOODS HOLE, Mass.—When Eric Betzig loaded his hand-built, “bleeding edge” super-resolution microscope into an SUV in 2007 and drove it up to the Marine Biological Laboratory (MBL) for biologists to “test drive” it, it was immediately embraced as a major breakthrough in […]

New Analysis Reveals Previously “Hidden Diversity” of Mouth Bacteria

This network analysis shows the distribution of oral sites in the human mouth based on the taxonomic units identified in ~6 million bacterial 16S rRNA gene reads by oligotyping. Samples were obtained from 148 healthy individuals; the oral cavity of each individual was sampled at 9 locations. Each circle represents a sample and is colored based on which oral site it is from. Clustering of the oral sites shows that samples from the same oral site across individuals are more similar to each other than samples from the different oral sites in a single individual.

The technique, developed by Marine Biological Laboratory (MBL) scientists, provides high taxonomic resolution of bacterial communities and has the capacity […]
