(Evangelyn Rodriguez) Humans have 23 pairs of chromosomes, only one of which determines a person’s sex-linked characteristics. The remaining 22 pairs contain bundles of genetic instructions that help determine the other, non-sex-related traits. Since the discovery of DNA, researchers have endeavored to learn all there is to know about these coded sequences, including how much they weigh. The Human Genome Project, which was launched in 1990, provided an answer to this. But in a new study published in the journal Chromosome Research, British researchers discovered that the mass of human chromosomes, which house all of a person’s DNA, far exceeds theoretical values. Even after accounting for all other components (i.e., histone proteins), all 46 chromosomes still weighed considerably more than the DNA they contained.

The Mysterious Otherworldly Sphere of Florida
(Brent Swancer) Every once and a while something is dug up or discovered somewhere that seems to defy all attempts to understand it. These anomalous objects are poked, prodded, and studied, yet refuse to give up their answers, often sparking talk of aliens and extraterrestrial intelligences. One very well-known account of such an object was found by chance in the U.S. State of Florida by an unsuspecting family. A perfect sphere with various unusual properties, it has gone on to fuel talk of all manner of UFO theories and conspiracy rumors, and remains an enigma to this day.
