A close-up look at the spliceosome, at last.
Major developments in cryo-electron microscopy in the past three or four years have led to the solution of a number of spliceosome structures at high resolution, e.g., the fully assembled but not yet active spliceosome (Bact), the spliceosome just after the first step of splicing (C), and the spliceosome activated for the second step (C*). Therefore 30 years of genetics and biochemistry of the ...

Monumenti, Musei e Gallerie Pontificie. This illustrates the state of planetary observation at the beginning of the eighteenth century. Most of the succeeding advances in this field have occurred in the past decade. Preface The technical triumph of manned landings on the Moon and the return of samples from the lunar surface has provided scientists with a unique opportunity to advance our unders...
متن کاملTidal Decay of Close Planetary Orbits
The 4.2-day orbit of the newly discovered planet around 51 Pegasi is formally unstable to tidal dissipation. However, the orbital decay time in this system is longer than the main-sequence lifetime of the central star. Given our best current understanding of tidal interactions, a planet of Jupiter’s mass around a solar-like star could have dynamically survived in an orbit with a period as short...
