Embryology shake-up backed
The new study has been prompted by indications from researchers at Australia's Casey Station which suggest the subglacial basins could make the East Antarctic ice sheet more vulnerable in a warming world. Satellite data suggest that the Totten Glacier, which dominates the ice of the Aurora subglacial basin, appears to be losing ice at its downstream edge. " We are getting more science done with...

Undeniably, the most pressing issue is the recent collapse of the economy, and Obama has laid out a plan incorporating both short-term economic stimuli, such as tax cu...
متن کاملTime-Dependent Seismology
The time variation of crustal velocities in tectonic regions is most reasonably attributed to stressinduced variations in crack porosity. The decrease in V•,/Vs before arthquakes is due primarily to a large decrease in Vp. This supports the Nur dilatancy hypothesis but not the effective stress hypothesis. New data from the San Fernando region verify the Vp drop, show that this drop cannot be en...
متن کاملAging: A Sirtuin Shake-Up?
The yeast sirtuin (Sir2) is a histone deacetylase that modulates yeast replicative life span by suppressing genome instability through chromatin modification. In this issue, Oberdoerffer et al. (2008) report that SIRT1, the mammalian ortholog of Sir2, is involved in DNA damage-induced chromatin reorganization, which promotes genome stability in mammalian cells.
