Water sources and environmental transmission of multiply resistant enteric bacteria in rural Bangladesh.
The role of different water sources in the spread of multiply resistant enteric bacteria was investigated in rural Bangladesh. The prevalence of resistance to commonly used antimicrobial agents in the faecal flora of village children and the water quality and prevalence of resistance in village water sources were studied. Most of the children studied (81%) had multiply resistant faecal coliform bacteria, i.e. bacteria resistant to at least three antimicrobials. Although tubewells provided water with low faecal coliform counts, 62% of household storage pots contained water with moderate to high counts. Most of the storage pots (76%) and each of the river and pond sites tested contained multiply resistant isolates.

Evidence that climate change can have a rapid effect on ocean circulation

Sudden shifts in temperature over Greenland and tropical rainfall
patterns during the last ice age have been linked for the first time
to rapid changes in the salinity of the north Atlantic Ocean,
according to research published Oct. 5 in the journal Nature. The
results provide further evidence that climate change can have a
direct and rapid impact on ocean circulation and chemistry.

"It's a very complicated system," said lead author Matthew Schmidt,
who carried out the work as a graduate student at the University of
California, Davis, and is now a visiting NOAA Climate and Global
Change Postdoctoral Fellow at the Georgia Institute of Technology.
"But when it responds, it responds big time."
