...long ago, high-protein bars were the space food of choice for dieters who wanted their sweet fixes in alternative form. But with diets such as Atkins and the Zone reinforcing the idea that carbohydrates are the main stumbling block to weight management, low-carb bars are crowding the racks near the registers at supermarkets, pharmacies and health-food stores. "They're so popular because people think, I'll have this instead of a candy bar," says Sharron Dalton, professor of nutrition at New York University. But experts warn that just because these bars are low in "net carbs...
...places on earth where you can stare a newly accused mass-murder suspect right in the face. Researchers there are using a powerful transmission electron microscope to examine a virus that was unknown to science just a month ago. This minuscule particle of protein-encrusted RNA is almost certainly the microbe that had, by last Saturday, infected more than 2,400 people in 19 countries--including up to 115 in the U.S.--and killed at least 89 since it began its rampage through the human population in China last fall. Projected onto a green phosphorescent screen by a beam...
VaxGen's AIDSVAX vaccine, for example, targets gp120, a protein on the surface of HIV that latches onto receptors on human immune cells. The virus can then break in, multiply and kill the cell. AIDSVAX has a synthetic version of gp120 that tricks the body into producing antibodies; when real HIV shows up, they're meant to bind to the protein and prevent attachment. But researchers now realize that gp120 can take many forms, and antibodies to one will not work on another. Researchers think that effective vaccines will need to combine gp120 with other approaches...
...wide receiver. “Keep in mind that he’s an athlete, and he’s going to be expending a lot of energy to burn this food off,” Pappas says. He describes his essentials for healthy living succinctly: protein, vegetables and water, “PVW.” “You utilize the PVW, and then decide how many fats and carbohydrates you want to sprinkle in,” Pappas says. He advises Marynick to trade the ranch dressing on his salad for some balsamic vinaigrette. Pappas is more...
Montacute has a “sensible diet” of steak tips, rice pilaf and vegetables, although Pappas would like to see a little more protein. “A piece of grilled chicken on a salad is a good thing, ladies,” Pappas tells Montacute and her friends. Pappas is realistic about the college diet: “It’s okay to go out on the weekend and do your beer and chicken wings, but come Monday, you’re back...
