Interesting Things with JC

1661: "The Earth's Core is Younger than its Surface"

Interesting Things with JC #1661: "The Earth's Core is Younger than its Surface" – A clock at Earth’s core runs slightly slower than a clock on the surface, and over 4.5 billion years that tiny relativity effect leaves the center of the planet about two and a half years younger than the ground above it.

1660: "The Adams Event"

Interesting Things with JC #1660: "The Adams Event" – A 42,000-year-old kauri tree held a carbon record from the Laschamps Excursion, when Earth’s magnetic field weakened, cosmic rays increased, and the upper atmosphere may have changed while the tree kept the evidence ring by ring.

1659: "Overmodulating the Carrier"

Interesting Things with JC #1659: "Overmodulating the Carrier" – WMEX engineers pushed AM modulation to the edge so the station sounded louder and denser than nearby signals, with audio processing that helped 1510 punch through static, car noise, fading, and crowded nighttime dial conditions.

1658: "HAVOC: The Airship of Venus"

Interesting Things with JC #1658: "HAVOC: The Airship of Venus" – NASA engineers studied a crewed airship that would float above Venus instead of landing on its deadly surface, because the planet’s upper atmosphere becomes far less extreme while the ground remains hot enough to destroy normal exploration hardware.

1657: "The Stonefly of British Columbia"

Interesting Things with JC #1657: "The Stonefly of British Columbia" – Stonefly nymphs cling to rocks in cold British Columbia rivers while scientists check whether the water can still support life; when the insects disappear, the river is usually warming, polluted, or losing oxygen, and the pattern reaches into forestry, mining, salmon habitat, and watershed monitoring.
