Focal adhesions come unstuck C rawling cells pick up after themselves before moving on. Ezratty et al. (1) show that cells use the endocytic protein clathrin to reabsorb the integrin receptors that attach them to surfaces, instead of simply leaving the molecules behind. Cells on the go gain traction by forming focal adhesions (FAs), temporary attachments to the surface. But if they can't break ...

The tropical paper wasp, Ropalidia (Icariola) fasciata (F.), nests on leaves of gramineous plants (Miscanthus sinensis Andus. and sugarcane) in Okinawa, where there are frequent, strong typhoons. In Taiwan and Java, where the effects of typhoons are less severe, most nests are on tree twigs. A similar difference is seen in nests of Ropalidia (I) marginata (Lepeletier) in the Northern Mariana Is...

Effective tuberculosis (TB) control in Canada depends on case-finding to discover infectious cases, investigation of contacts of those with TB, appropriate treatment (with drugs to which the organisms are susceptible and user-friendly regimens to encourage adherence), case holding (which includes registration of the patient and methods of ensuring that patients take their medications until they...

Bail Information Schemes gather and provide information on a defendant’s community ties to the court. Past evaluations have concluded that schemes are effective because more defendants are granted bail. However, the evaluations include possible confounds and other limitations, thus threatening the validity of their findings. They are also incompatible with research showing that magistrates do n...

Evolutionary psychology has become a popular frameM'ork for studying jealousy. Much of this popularity can be attributed to work by Buss and his colleagues showing an apparent relation between an individual's sex and jealousy for certain types of infidelity (i.e., sexual vs. emotional) that is consistent with evolutionary theory (Buss, Larsen, Westen, & Semmelroth, 1992). In two .studies, we ta...
