...biologists, that's huge. The only way to account for that particular chemistry is if the salts have dissolved out of rocks in the interior of Enceladus into a large quantity of standing water, as would occur if the moon had a subsurface ocean. "Both components [table salt and carbonates] are in concentrations that match the predicted composition of an Enceladus ocean," says Postberg. "The carbonates also provide a slightly alkaline pH value, which could provide a suitable environment on Enceladus for life precursors...

Research also shows that the conditions occur together in families more often than they would by chance.

Inspections that now occur an average of once every 10 years would take place as often as once every six months for certain items.

But institutional relapses can occur: human-rights lawyers and Palestinians with experience in Israeli prisons say some violent interrogation techniques have returned in recent years...
