The calls started coming in late on Tuesday and early Wednesday: offers of dry ice, freezer space, coolers. By the end of Thursday there were dozens more: A researcher at Weill Cornell Medical College would clear 1,000 tanks to save threatened zebra fish; another, at Cold Spring Harbor Laboratory, promised to replace some genetically altered mice that were lost; and a doctor at the Children's Hospital of Philadelphia even offered take over entire experiments, to keep them going.
As hurricane-driven waters surged into New York University research buildings in Kips Bay, on the East Side of Manhattan, investigators in New York and around the world jumped on the phone to offer assistance — executing a reverse Noah's ark operation, to rescue lab animals and other assets from a flooding vessel.
"I've had 43 people who have offered to help so far, and some of them are direct competitors," said Gordon Fishell, associate director of the N.Y.U. Neuroscience Institute, who lost more than 5,000 genetically altered mice when storm waters surged the night of Oct. 30, cutting off power. "It's just been unbelievable," he said. "It really buoys my spirits and my lab's."
Staff members at N.Y.U. worked around the clock to preserve research materials, running in and out of darkened buildings without elevator service, hauling dry ice and other supplies up anywhere from 2 to more than 15 floors.
The university's medical center also got instant help, from almost every major research institution in the area.
The response reflects large shifts in the way that science is conducted over the past generation or so. Individual labs always compete to be first, but researchers increasingly share materials that are enormously expensive and time-consuming to reproduce. The loss of a single cell line or genetically altered animal can slow progress for years in some areas of biomedical research.
"We are totally dependent on each other in the life sciences now, for a very large number of cell lines and extracts, research animals and unique chemical tools and antibodies that might not have backup copies anywhere in the world, or in very few places," said Dr. Steven Hyman, director of the Stanley Center for Psychiatric Research at the Broad Institute of M.I.T. and Harvard. "Losing any of these tools tears a significant hole in the entire field."
Danny Reinberg, a professor of biochemistry at N.Y.U.'s medical school, has studied genetics for 30 years, accumulating valuable mice strains and stocks of extracts from cell nuclei that would be extremely difficult to replace. The extracts must be stored at minus 112 degrees Fahrenheit.
Dr. Reinberg said he lost all of his mice: nine strains, including more than 1,000 animals that died in the storm surge. But he managed to save all of the cell extracts by moving some containers into freezers at N.Y.U. labs that weren't affected and others to the Rockefeller, Columbia and Cornell medical centers, each of which cleared space, he said.
"We were able to save many things; it was just phenomenal to get that kind of help," said Dr. Reinberg, whose house in New Jersey has had no power.
"Later in the week, at a Starbucks, I could finally download all my e-mail, and there were messages from people at the University of Pennsylvania and the Howard Hughes Medical Institute, asking how they could help us re-establish the mouse lines we lost," he said.
Some scientists have become interdependent because their students, who develop a specialty in specific tissues or animals, often move among labs. Research projects sometimes draw on experiments or analyses the students worked on at more than one place.
One researcher working in Dr. Fishell's lab was formerly a student of Dr. Stewart Anderson of the Children's Hospital of Philadelphia, who sent Dr. Fishell a text message on Wednesday to offer help. "I told him that even if it costs money, we're happy to keep experiments rolling, if we're able to," Dr. Anderson said.
By late Thursday, freezer space in minus-112-degree units was extremely tight in the city. So was dry ice.
Susan Zolla-Pazner, director of AIDS research at the Manhattan Veterans Affairs Medical Center, had lost power in her 18th-floor lab in the department's building at 23rd Street and First Avenue. She finally hired a company to haul her 20 freezers-full of specimens, for safekeeping.
"We spent all of Tuesday and Wednesday hauling 1,300 pounds of dry ice up to the 18th floor, using the stairs, to stabilize the freezers first," said Dr. Zolla-Pazner, who is also a professor of pathology at N.Y.U. School of Medicine. "And the dry ice people would only take cash. I have about 25 to 30 people working for me, and everyone was out there on 23rd Street, reaching into their pockets to get what we needed. It was a herculean and heroic effort on the part of everyone here, and that is the story that needs to be told."
