NYC has been using aerial photography for over 100 years to catalog and measure the city. Thanks to some superb data preservation, you can explore some amazing aerial photography data going back to 1924.

The cost of DNA sequencing has fallen faster than Moore's Law. Since 2001, the National Human Genome Research Institute (NHGRI) has tracked costs at its funded sequencing centers — from $95 million per genome in 2001 to around $500 today.

Genome sequencing costs fell 190,000-fold since 2001. Data here stops at 2023 and I can't seem to find reliable sources since then.

As a new parent, my mind immediately went to movie-viewing volume. With a four-month-old, I am not exactly plugged into movie culture—or really any culture unrelated to said four-month-old. So I wanted to know whether this “parent tax” is universal: Do we watch fewer films as our responsibilities grow?

The answer, unsurprisingly, is yes. In the MovieLens dataset, average rating volume peaks among users ages 25 to 34, then declines with each passing decade.

Every so often the Earth produces a signal that is impossible to ignore. This graph is one of them. It shows sea-surface temperatures in the Niño 3.4 region of the equatorial Pacific, one of the most important parts of the Earth's climate system. Each blue line represents a different year since 1982. The red line is this year. It doesn't just set a new record. It has departed entirely from the range of previous observations.
