The girls, ages 11, 13 and 14, survived the attack, but “a clear suspect” was never pinpointed and the case went cold — until now. Indianapolis police say investigators using “forensic genetic genealogy” have identified the attacker.

Authorities say human remains found in rural Indiana in 1982 have been identified as those of a Wisconsin woman who was 20 when she vanished more than four decades ago.

At one Stone-Age-era archaeological site in southern Denmark on the island Lolland all of the artifacts have been sealed in mud since the Mesolithic period 6,000 years ago. One artifact is what researchers are calling an early version of chewing gum, made from birch pitch that oozed from birch bark after being heated.

It's interesting that modern anthropologists can do more than just study fossil bones and teeth. Ancient remains sometimes contain surviving DNA, and this has let scientists study the genomes of both the Neanderthals and the Denisovans.

Researchers at the University of Montreal have created a programmable thermometer made from DNA. It's 20,000 times smaller than the width of a human hair.

Tardigrades are little animals that can survive dehydration, radiation, and survive in outer space without a space suit. As strange as all of the above sounds, they are apparently even stranger.

Dogs and their closest wild relatives, wolves, both came to North America from Eurasia. The earliest dogs in the Americas were introduced at least ten thousand years ago.
