Summer at MBL is busy, beautiful, and quickly over, but time is still devoted to planning for the future. Students and early-career scientists looking for their next steps don’t have to go far for advice, because each Wednesday during lunch,the SUCCESS program tackles an important aspect of career planning.

From crafting a resumé to getting funded to choosing a mentor, different career topics are addressed each week by a panel of successful scientists.. The atmosphere is informal, so attendees are comfortable asking questions and sparking discussion.

A quick survey of attendees at last week’s SUCCESS workshop proved roughly half were undergraduates, a quarter were graduate students, and a quarter were post-docs, with a few research technicians and assistants as well. The panel discussion on “Choosing Your Career: Academia and Other Not-for-Profitsoffered something for everyone to consider, regardless of career stage.

Panelist Steve Zottoli, MBL’s Co-Director of Education, stressed the importance of mentors. “Finding the right mentor is so critical. You have to take an active role in finding the right mentor who believes in you so much that they take you to the next level,” he said. As students and early-career scientists find their mentors and their places in the scientific community, the SUCCESS series makes sure they are not without good advice.

SUCCESS workshops are held on Wednesdays through July 29 in the Meigs Room, Swope Center, with lunch beginning at 11:30 AM. The full schedule is here: http:/

The SUCCESS series (Shaping and Understanding Career Choices in Education, Science, and Self) is a project of a dedicated, MBL community-wide committee led by Bill Reznikoff, MBL Director of Education.

The MBL’s collecting boat, the Gemma, has had a few passengers from Woods Hole Oceanographic Institution of late: Aran Mooney, a biologist, and Casey Zakroff, an MIT-WHOI Joint Program graduate student. Mooney and Zakaroff are studying the impact of ocean acidification on squid, using data they collected with the help of the Gemma’s captain and crew. (Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere.)

Along with being a key species in the oceanic food web, squid have a multimillion-dollar impact on the human food industry. They are a vital component to the marine ecosystem’s wellbeing, as well as ours, making it crucial to monitor any risks that threaten healthy growth.

In the film, Is Ocean Acidification Affecting Squid?, produced by Daniel Cojanu, Mooney and Zakroff show how rising pH levels may be impacting a local and much prized marine species.


Kristin Gribble, assistant research scientist in the MBL’s Bay Paul Center, was awarded the “Runner-Up Best Paper Prize 2014” by the journal Aging Cell and the Council of the Anatomical Society. The award recognizes her paper, “Maternal caloric restriction partially rescues the deleterious effects of advanced maternal age on offspring” (Gribble K.E., G. Jarvis, M. Bock and D.B. Mark Welch Aging Cell 13: 623-630, 2014).

Gribble and colleagues discovered that advanced maternal age reduces the lifespan, fecundity, and size of offspring in the rotifer (B. manjavacas), a tiny aquatic animal that is becoming established as a model organism for aging research. However, the researchers were able to reduce the severity of some of these effects by putting the mothers on a calorie-restricted diet. More information is here.

It’s now been five days since the tragic earthquake struck Nepal. The official death toll has passed 5,000, but this doesn’t begin to tell the story of devastation in Nepal and neighboring regions of China and India that has affected millions of people in the region, wiped out entire villages, and destroyed ancient landmarks of cultural, religious and historic significance.

From the other side of the world, where we finally welcome spring to Woods Hole, it is difficult to grasp the scope of this disaster and the scale of suffering. This is why we tend to focus on specific events or images – the video of avalanches on Mt. Everest, or the neurosurgeon/journalist Sanjay Gupta performing brain surgery on an injured child, or a woman in Kathmandu who was pulled alive from the rubble, 36 hours after her 5-story apartment building came crashing down on top of her. Those images help us stay connected to the story, but ultimately fail to convey the massive scale of suffering, when three stories so quickly blur to become 3,000 and then 3 million.

Science – no less than the world around us – is increasingly a global enterprise. This is especially so at the MBL, where we regularly welcome scientists, staff, students and visitors from around the world.

And this is why we should pause – even for just a moment – to think about our colleagues and friends, some of whom, even unknown to us, have relatives, extended family members, classmates or neighbors who come from Nepal and the regions so affected by this tragedy. Today, we can all be Nepalese, and they can all be part of the MBL community.

Thank you for your thoughts and for what you do.

The startling discovery of a contagious cancer in steamer clams, published this week in the journal Cell, had its origins at the MBL.

Carol Reinisch began studying a fatal, leukemia-like disease of soft-shell clams (Mya arenaria) at the MBL in the mid-1970s, when it was causing major die-offs among distinct bivalve populations. This week, scientists announced that the disease is a contagious form of cancer that has been transmitted between clam populations from New York to Prince Edward Island, Canada. The study was conducted by Michael Metzger and Stephen P. Goff of Columbia University, Jim Sherry of Environment Canada, and Reinisch.

Infectious cancer (or “super metastasis”) is known in only two other instances in nature: as a venereal disease in dogs and as a facial tumor in Tasmanian devils, according to an article about the clam leukemia in Science.

Reinisch, a few years ago, thought the clam disease might be caused by a virus, and she brought it to Goff’s attention. Metzger and Goff, she says, “conducted the truly elegant molecular biology to show the cancer is externally derived.”

Through genetic analysis of numerous sick clams, the team showed that while their cancer cells were nearly identical, the cancer cells did not match the genomes of their host clams. This indicates the cancer cells likely descended from a single, original clam cell “gone rogue,” which then multiplied and spread to nearby clams. How the disease was transmitted is still unknown.

Steamer clams are eaten by human beings and are an important commercial fishery. However, researchers say there is no health risk to humans who eat diseased clams. “Nobody eats them raw. When you steam or boil them, it kills all the cells,” Reinisch says.

Reinisch has studied this clam and bivalve disease for decades because “it’s one of the best and unique models of carcinogenesis in nature that we have,” she says. She carried out research at MBL for more than 30 years, first as a Whitman summer investigator and then, from 1998 to 2005, as a year-round scientist. She moved her lab to the MBL in order to explore Mya arenaria as a model system for cancer. Formerly, she was a Department Chair of Comparative Medicine at Tufts Veterinary School.

Reinisch’s earlier work indicated that the spread of the clam leukemia has an environmental component. “For whatever reason, the [cancer] transmission seems to be easier in stressed areas,” she says. “When we used to collect clams in New Bedford, Mass., we knew exactly where to find the ones with leukemia. The clams in a PCB contaminated site were much more liable to have the disease.”

Currently, Reinisch collaborates with Environment Canada in Burlington, Ontario, and is identifying the range of this transmissible cancer. She has studied bivalves as far north as Alaska and the Arctic and hopes to conduct field research in Antarctica in the coming year.
