. >> reporter: in this baltimore lab, dr. curt civin researches leukemia in search of a cure. it's hardly a political job, but these days he's keeping a close eye on the federal budget. you see, the sequester-- the severe spending cuts headed our way in january-- could affect him. if it takes affect, it will cut an estimated $2.5 billion from the national institutes of health. dr. civin and researchers like him depend on grants from the institutes for funding. >> it's tough enough to cure cancer. tough battle. going to take a long time. to cut the funding, to have unevenness, to take a project all the way, and then say, "well, we can't scale this up the way we should, or even maintain it the way we should?" how can we do that. and it's not good for us. >> reporter: dr. civin says labs across the country may have to lay people off if their grants are defunded or reduced. eventually, that could lead to less research and fewer cures. he's especially worried about young scientists. some of them have new- potentially breakthrough- ideas, but might struggle to get financial backing
