Death and the shrinking nucleus
Cells need backward motor to move forward ytoplasmic dynein associates with a variety of intracellular cargos and pulls them toward the minus ends of microubules. But this retrograde motor protein is also essential for forward cell migration, as Dujardin et al. demonstrate on page 1205. After observing dynein and its associated regulatory proteins at the leading edges of migrating cells in a mo...
متن کاملMating induces shrinking and death in Caenorhabditis mothers.
Interactions between the germ line and the soma help optimize reproductive success. We discovered a phenomenon linking reproductive status to longevity: In both hermaphroditic and gonochoristic Caenorhabditis, mating leads to female shrinking and death, compressing postreproductive life span. Male sperm induces germline- and DAF-9/DAF-12-dependent shrinking, osmotic stress susceptibility, and s...
متن کاملThe amazing shrinking laboratory.
A new monoclonal antibody to epithelial membrane antigen (EMA) E29. A comparison of its immunocytochemical reactivity with polyclonal anti-EMA antibodies and with another monoclonal antibody, HMFG-2. Summary Two polyclonal rabbit antibodies to epithelial membrane antogen (EMA), two mouse monoclonal antibodies (E29 and HMFG-2), and a "cocktail" of these two monoclonals have been compared using a...
متن کاملThe Incredible Shrinking Torus ⋆
Using M(atrix) Theory, the dualities of toroidally compactified M-theory can be formulated as properties of super Yang Mills theories in various dimensions. We consider the cases of compactification on one, two, three, four and five dimensional tori. The dualities required by string theory lead to conjectures of remarkable symmetries and relations between field theories as well as extremely unu...
متن کاملShrinking the Authentication Footprint
Developers create paths for users to tread. Some users will stay on the beaten track; others will diverge and take risky shortcuts. If user-preferred and developer-created paths diverge too much, it is time for the developer to consider a new path. A case in point is the humble password. They fill an important developer need: a cheap and easy mechanism to control access and enforce accountabili...
