...that cell that is suddenly sparking the interest of cancer researchers and molecular biologists around the world. Known as a cancer stem cell, it could be the culprit behind a malignant tumor's nasty habit of recurring year after year and popping up in distant parts of the body long after the primary growth is gone. Studies of that cell are helping scientists unravel some of cancer's deepest secrets and leading doctors closer to the ultimate goal of any cancer therapy--a cure. Think of the stem cell as a tumor's master print; as long as the original...
...swimming and crawling about the planet for 350 million years. But their future is hardly assured. A global assessment of the state of this entire class of vertebrates found that nearly one-third of the 5,743 known species are in serious trouble. Climate change may well be the culprit in most cases, either directly or indirectly. The home habitat of the golden toad (at right, bottom) in Costa Rica moved up the mountain until "home" disappeared entirely. More than two-thirds of the 110 species of colorful harlequin frogs in Central and South America, two shown above, have also...
...perhaps psychology was the chief culprit in the Crimson’s eight-game league losing streak that dragged the team to the bottom of the standings. Sixty years without a title can have a seriously deleterious effect on a team’s psyche, can form a rut of perpetuating mediocrity that becomes near impossible to escape from. Albany was lucky, then, to get that first NCAA bid so soon in its history of Division I play...
Slobodan Milosevic was not the only culprit in the bloody breakdown of multi-ethnic Yugoslavia, but he can be assigned the bulk of responsibility. He had a unique talent for bringing out the worst in everything and everybody he touched. He brought out the worst in Serbs, and provoked retaliatory responses from the Croats, Bosnians, and Albanians. A political opportunist, he picked up ideologies such as nationalism, socialism, and even democracy itself, and perverted them to suit his own needs, discarding them when they no longer served his purposes. He burned bridges between nations and peoples that took centuries...
...aftermath of University President Lawrence H. Summers’ resignation, a range of theories has been offered to explain what went wrong. Generating much heat but little light, every media outlet blamed a different culprit, from a hard-left faculty of “feminazis” to structural problems in Harvard’s system of governance. Unfortunately, with the Faculty of Arts and Sciences’ continued silence on the issue, what Pforzheimer House Master James J. McCarthy called “uninformed and/or misinformed” speculation may be the best explanation that the Harvard community gets...
