A traditional cassette tape holds roughly 10 to 12 songs on each side, but 328 feet of this DNA cassette tape could hold the same amount of data in over 3 billion songs. The prototype’s total capacity is 36 petabytes of data, the same size as 36,000 terabyte hard drives.

In a TV interview, Kash Patel, the director of the F.B.I., said investigators had found physical evidence connecting the suspected gunman with the fatal shooting of Charlie Kirk in Utah.

The DNA tissue sample taken from a baby left in an Iowa City landfill in 1992 was so "degraded and contaminated" that traditional DNA testing couldn't help investigators identify the infant or his mother.

The hearing broke along starkly partisan lines. Republicans rallied support for Patel even as Democrats said he had debased the integrity of the nation’s premier federal law enforcement agency.
