The female mice that received male donor cells consistently showed Y-chromosome-positive insulin-producing islet cells, indicating that the introduced spleen cells contribute to islet...

Yet the rationale for the use of many of these approaches is obtuse ?one might even be tempted to write misleading, he says. ...

Contrary to common wisdom, scientist discovers some mammals can smell objects under water

What animals can tell us about hemorrhage, organ transplants and aging

...without suffering significant muscle atrophy They follow migrating birds thousands of miles to understand how they fuel their metabolisms for grueling transoceanic flights They slog through wetlands, studying frogs that literally freeze during the winter, then hop away in the spring as though nothing unus...

Fire ant-attacking fly spreading rapidly in Texas

...hem in with ants from a disturbed mound. The flies follow the ants into the traps and then become stuck on strips of flypaper when they take a break from attacking their victims. Researchers place traps around fire ant mounds along roads and analyze the flies they catch. They have found the introduced pho...

Nice guys do finish first in lizards' evolutionary race

... different behaviors, which Sinervo has discovered follow "rock-paper-scissors" cycles of lizard lust. Orange-throated lizards are the big bullies, roaming far from home to raid female territories and mate. They generally beat blue-throated lizards, the stay-at-home dad types. The blues stick close to hom...

AIDS vaccine research offers new insights on survival

...0 days -- Letvin and his VRC colleagues decided to follow the monkeys for an additional 750 days, a total of 850 days or nearly three years. "We found that the vaccinated monkeys lived significantly longer than the unvaccinated monkeys following infection and that levels of memory CD4+ cells remained signi...

Immune system police learn early and sometimes badly

...g receptors on individual cells, they were able to follow the cells after they left the thymus and see if they changed. Another key question was how regulatory T cells, which make up about 5 percent of the total T cell population, can control millions of roaming T cells. They found it was a simple matter ...

Movie spies on malaria parasite's sneaky behavior

Bedsores and bald hides: Novel roles revealed for a 'scaffolding' protein

.... When cells of normal hair follicles die, they follow a specific and genetically controlled death program. The team found that the K17 cytoskeleton protein is required to physically interact with a protein that is known to activate cell death and prevent follicle cells from dying before they finish thei...

Study supports 'urgent' need for worldwide ban on lead-based paint

...t. Many Third World countries, says Clark, did not follow suit, and continue to manufacture and sell lead-based paints that would be prohibited in the United States and in some other countries. "We've known for years that there are good substitutes for lead in paint," he continues, "so it's absolutely in...

On the track of tiny larvae, a new model elucidates connections in marine ecology

...opulations. Although tiny larvae are impossible to follow directly, advances in modeling ocean currents have made it possible to predict larval movements. However, until now it has remained difficult to test these movement predictions in the field by comparing the model to data from population genetic studi...

How satellite tracking revealed the migratory mysteries of endangered Atlantic loggerhead turtles

...scribe how they used satellite tracking systems to follow the journeys of ten turtles from Cape Verde, West Africa, which is one of the world's largest nesting sites for loggerheads and a hotspot for industrial fishing. What they found could turn current conservation strategies upside down, as the team disc...

First 'encyclopedia' of nuclear receptors reveals organisms' focus on sex, food

...d that the activity of more than half of receptors follow rhythmic cycles, so coordinated changes in receptor activity helps explain the cyclic behavior of metabolism. This also suggests that the superfamily acts as a mega-network to influence metabolism, rather than in a series of independent signaling pat...
