The parent cell becomes asymmetrical: it collects a set of special molecules, including Prospero and other proteins, in the area that will bud off and become the specialized cell.

About 39 percent of attacks happen during the March-May harvest season, when farmers often sleep in their fields to protect their crops from bush pigs; more than 27 percent of attacks occur in fields.

These two signals play a vital role in inducing allergic inflammation. These findings suggest that antioxidant substances may be useful in forestalling ...Building a better mouse model of lung cancer: FHIT counts
