1775: "The Signal Einstein Thought We Might Never Hear"

Interesting Things with JC #1775: "The Signal Einstein Thought We Might Never Hear" – Two LIGO detectors register the same gravitational-wave signal seven milliseconds apart as two black holes merge 1.3 billion light-years away. The signal lasts about two-tenths of a second, while the instruments measure changes smaller than the width of a proton after decades of attempts failed to detect one.

1773: "The Clock Behind Instant Replay"

Interesting Things with JC #1773: "The Clock Behind Instant Replay" – Two instant-replay feeds showing the same moment can reach officials milliseconds apart. Every step through processing, switching, transmission, encoding, and decoding can add hidden latency, so replay has to determine when each frame actually occurred instead of trusting when it arrived.

1770: "When a Parasite Rewires Behavior to Spread Itself"

Interesting Things with JC #1770: "When a Parasite Rewires Behavior to Spread Itself" – Infected Texas field crickets were sterile or producing barely moving sperm, but they kept mating, and infected males courted females sooner than healthy males. The virus was disrupting the immune signals that normally slow courtship during illness while still spreading through sexual contact.

1769: "Football Brain Injury Cover Up"

Interesting Things with JC #1769: "Football Brain Injury Cover Up" – Dr. Bennet Omalu found CTE in Mike Webster’s brain, and the NFL’s concussion committee challenged the published finding and called for its retraction. More former players were diagnosed after death, and twelve years later researchers found CTE in 110 of 111 donated brains from former NFL players.

Interesting Things with JC #1766: "Autistici/Inventati - The Network Behind the Network" – Autistici/Inventati runs encrypted email, private chats, websites and other infrastructure designed to make users harder to monitor. By 2026, violent radical groups and the PKK were among those using its services, while U.S. authorities say the collective screened applicants and provided access to groups it believed shared its politics.

1762: "The Man Who Guarded the Skies During the Cold War"

Interesting Things with JC #1762: "The Man Who Guarded the Skies During the Cold War" – In 1975, Daniel “Chappie” James Jr. took command of NORAD as its radar and warning systems searched North America’s approaches for Soviet bombers and missiles. Thirty-two years after earning his wings at Tuskegee in a segregated military, he was now responsible for forces guarding the skies over the United States and Canada.

1759: "Gestalt Language Processing"

Interesting Things with JC #1759: "Gestalt Language Processing" – A child repeats a phrase they heard hours, days, or weeks earlier, sometimes using the same tone and rhythm. This delayed echolalia can communicate something, but Gestalt Language Processing makes a bigger claim: that some children learn language first as whole phrases and later break them into smaller pieces, an idea researchers still debate.

1756: "What Happens When You Skip Sleep?"

Interesting Things with JC #1756: "What Happens When You Skip Sleep?" – Stay awake long enough and adenosine signaling increases sleep pressure while caffeine can temporarily block the feeling of it. Attention, judgment, and memory become less reliable, and eventually the brain can force seconds-long microsleeps into wakefulness even while you are still functioning.

1749: "Ouzel Lake and the Dangers of Alpine Swimming"

Interesting Things with JC #1749: "Ouzel Lake" – Ouzel Lake can look inviting after a 4.9-mile summer hike, but the mountain water can remain cold enough to trigger an involuntary gasp and rapid breathing almost immediately. Stay in, and cold can begin taking away strength and coordination while you're still nearly five trail miles into Rocky Mountain National Park.

1745: "The Wow! Signal"

Interesting Things with JC #1745: "The Wow! Signal" – A radio telescope in Ohio detected a powerful narrowband signal from the direction of Sagittarius for 72 seconds, matching the rise and fall expected from a fixed source in the sky. The signal vanished before the telescope’s second beam crossed the same region, and nearly fifty years of searches have never detected it again.
