Drosophila Development: RNA Interference ab ovo
A novel protein required for RNA interference in Drosophila, Armitage, was identified in a screen for genes involved in embryonic axis formation. In armitage mutants, oocyte polarity and the regulation of oskar mRNA translation are impaired, suggesting that RNA silencing regulates the first steps of Drosophila development.

O n April 10, 1908, at the general session of the Fourth International Congress of Mathematicians held in Rome, Gaston Darboux presented a talk by Henri Poincaré (1854–1912) entitled The Future of Mathematics (Poincaré was unfortunately unable to deliver the talk himself). The original can be found on the web at: http://gallica. bnf.fr/ark:/12148/bpt6k17083c/f934n10. capture. It is now a full c...
متن کاملPreface Henri Darmon
Modular curves and their close relatives, Shimura curves attached to multiplicative subgroups of quaternion algebras, are equipped with a distinguished collection of points defined over class fields of imaginary quadratic fields and arising from the theory of complex multiplication: the so-called Heegner points. It is customary to use the same term to describe the images of degree zero divisors...
