Is there a link between oral health and the rate of cognitive decline?

Science Daily - Fri, 01/04/2016 - 11:37am
Better oral hygiene and regular dental visits may play a role in slowing cognitive decline as people age, although evidence is not definitive enough to suggest that one causes the other. New findings come from the first systematic review of studies focused on oral health and cognition -- two important areas of research as the older adult population continues to grow, with some 36 percent of people over age 70 already living with cognitive impairments.

Reddit Deletes Surveillance 'Warrant Canary' In Transparency Report

Slashdot - Fri, 01/04/2016 - 11:30am
Arthur Dent '99 writes: Today, Reddit deleted wording in its transparency report that would normally indicate that they had not received any "national security letters" or "other classified requests for user information." Such "national security letters" contain penalties for telling others about the request, as the government wishes to keep the request secret. However, because Reddit had placed pre-existing wording in their transparency report in the event of such a letter, they were able to simply delete the existing wording to passively inform others that a request had been received, without actually saying anything at all. This usage of pre-existing wording is known as a "warrant canary" to indicate danger, such as real canaries were used in the past to indicate the presence of deadly gases in coal mines.
