When smell cells fail they call in stem cell reserves

Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. These reservists normally lie around and do nothing, but when neighboring cells die, the scientists say, the stem cells jump into action. A report on the discovery will appear online next week in Nature Neuroscience. “These stem cells a...

Vaccine targets tumors where they live

Vaccine strategies are being designed to battle cancer, but their use for metastatic melanoma is a challenge. Effective vaccines against established tumors require tumor-reactive T cells to traffic to the sites of the tumors and are locally activated there in order to kill cancer cells. A problem is that the T cells lose their tumor-killing power once they reach the environment surrounding the tu...

Worms know bad food when they smell it

For most people, just a whiff of food that has made them sick in the past is enough to trigger a wave of nausea ?and to prevent them from eating that food again.

The new approach, called Cardiocerebral Resuscitation, is dramatically different from guideline-directed CPR procedures. Because of its importance, the editors of the American Journal of Med...

- About eight percent of the weight of a box of corn flakes is corn. Less than five percent of the price of a box of corn flakes represents the cost of the corn - the rest is transportation, packaging, Super Bowl commercials, little plastic-wrapped toys for your kids, and more. Heck, the price of the box alone probably exceeds the cost of the co...
