Are Astronomers Wrong About Dark Energy?

An anonymous reader shared this report from CNN:

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.

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....

Three decades after RFC 1883 promised to future-proof the internet by expanding the available pool of IP addresses from around 4.3 billion to over 340 undecillion, IPv6 has yet to achieve the dominance its creators envisioned. Data from Google, APNIC and Cloudflare analyzed by The Register shows less than half of all internet users rely on IPv6 today.

Challenges Face European Governments Pursuing 'Digital Sovereignty'

The Register reports on challenges facing Europe's pursuit of "digital sovereignty": The US CLOUD Act of 2018 allows American authorities to compel US-based technology companies to provide requested data, regardless of where that data is stored globally. 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)...
