Some of Your Cells Are Not Genetically Yours

Every human body contains a small population of cells that are not genetically its own -- cells that crossed the placenta during pregnancy and that persist for decades after birth. These "microchimeric" cells, named after the lion-goat-serpent hybrid of Greek mythology, have been found in every organ studied so far, though they are exceedingly rare: one such cell exists for every 10,000 to 1 million of a person's own cells.

'The Cult of Costco'

Costco's consistency -- from its $1.50 hot dog and drink combo to its functional shopping carts and satisfied employees -- has produced what The Atlantic calls a "cultlike loyalty" among members at more than 600 locations across the U.S. Its annual membership costs $65.

DHS Says REAL ID, Which DHS Certifies, Is Too Unreliable To Confirm US Citizenship

An anonymous reader shares a report: Only the government could spend 20 years creating a national ID that no one wanted and that apparently doesn't even work as a national ID. But that's what the federal government has accomplished with the REAL ID, which the Department of Homeland Security (DHS) now considers unreliable, even though getting one requires providing proof of citizenship or lawful status in the country.

This places European organizations in a precarious position, as it directly clashes with Europe's own stringent privacy regulation, the General Data Protection Regulation (GDPR)...
