Harvard scientist Avi Loeb speculated that NASA’s recently released photos of 3I/ATLAS could potentially point to its artificial origins — and even wondered if the so-called comet was purposely targeting and sweeping meteorites out of its path. He posited his theory in a viral new blog post on Medium.

The new study involved taking a fresh look at the "Altamura Man," which is an exceptionally well-preserved Neanderthal skeleton covered in a thick layer of calcite, sometimes called "cave popcorn." The researchers' findings suggest that the size of Neanderthal noses might not have had anything to do with living in cold temperatures.
