Uranium in aragonitic marine bivalve shells
a r t i c l e i n f o Uranium concentrations in foraminiferal and coral skeletons track oceanic [CO 3 2 − ] and can be useful as a proxy of ocean acidification, but this pH proxy is yet to be investigated in bivalves. Two Saxidomus giganteus shells from the industrialized Puget Sound (WA, USA) and one from the more pristine Kodiak Island (AK, USA) were sampled through ontogeny for U/Ca using la...

متن کاملBuilt-in mechanical stress in viral shells.
Mechanical properties of biological molecular aggregates are essential to their function. A remarkable example are double-stranded DNA viruses such as the φ29 bacteriophage, that not only has to withstand pressures of tens of atmospheres exerted by the confined DNA, but also uses this stored elastic energy during DNA translocation into the host. Here we show that empty prolated φ29 bacteriophag...
متن کاملFatigue fractures of the fibula.
In (lescribing certain fractures of the fibula, sustained without violence, the writer (Burro ,s’s I 940) expressed the hope that further cases would be published so that something COU1(l be learnt of these uncommon fractures. Additional cases have now been described. The writer has encountered five other personal cases, and scrutiny of the literature has revealed at least one pre ’i us case (D...
متن کاملA large metabolic carbon contribution to the dC record in marine aragonitic bivalve shells
It is well known that the incorporation of isotopically light metabolic carbon (CM) significantly affects the stable carbon isotope (dC) signal recorded in biogenic carbonates. This can obscure the record of dC of seawater dissolved inorganic carbon (dCDIC) potentially archived in the shell carbonate. To assess the CM contribution to Mercenaria mercenaria shells collected in North Carolina, USA...
