Scientists have known for more than two decades that cancer is a disease of the genes. Something scrambles the Dna inside a nucleus, and suddenly, instead of dividing in a measured fashion, a cell begins to copy itself furiously. Unlike an ordinary cell, it never stops. But describing the process isn't the same as figuring it out. Cancer cells are so radically different from normal ones that it's almost impossible to untangle the sequence of events that made them that way. So for years researchers have been attacking the problem by taking normal cells and trying to determine...
...shock-absorbing disks between the vertebrae and the facet joints, at the back of each vertebrae, that act as brakes to rotation. Each disk is a round ligament, made up of an annulus, which is like a multilayered collagen basket that absorbs rotational stress, and a lighter-density liquid nucleus that absorbs compression. The layers of the annulus are woven for maximum absorption. But it doesn't take much to tear this basket. "You can tear the annulus with no more than 3[degrees] of sudden loaded rotation," Watkins says. "If the disk ruptures into the spinal canal...
...soon divided into separate specialties. Enrico Fermi, a supremely self-assured Italian American born in Rome in 1901, was the last great physicist to bridge the gap. His theory of beta decay introduced the last of the four basic forces known in nature (gravity, electromagnetism and, operating within the nucleus of the atom, the strong force and Fermi's "weak force"). He also co-invented and designed the first man-made nuclear reactor, starting it up in a historic secret experiment at the University of Chicago on Dec. 2, 1942. In the famous code that an administrator used to report...
...gene into the nucleus of a cell? The trick, researchers discovered early on, is to take advantage of the infectious power of viruses; burrowing into cells is second nature to them. A virus is nothing more than a tiny strip of DNA or RNA crammed into a protein envelope. Using the tools of molecular biology, scientists render the virus harmless by deleting some or all of its genes, splicing the therapeutic gene into the remaining genetic material and, in a laboratory Petri dish, mixing it with human cells. The altered virus, now called a carrier or vector, can deliver...
Storey, Scorsune, Moore and Morrell provide asolid nucleus for the defense. The unit will be aphysically imposing one, as six of the backlinersweigh in at least 190 pounds. The remaining twoslots will be a competition between twosophomores, Liam McCarthy and Tim Stay, and twofreshmen, Leif Ericson and Peter Capouch...
