Research on human tails is no recent development, though. In 1875, Darwin noted in The Descent of Man how “in certain rare and anomalous cases,” humans “form a small external rudiment of a ...

When choosing between heads or tails, you may want to rethink your assumption that the odds are 50/50, according to researchers from the University of Amsterdam.

Everyone knows the flip of a coin is a 50-50 proposition. Only it's not. You can beat the odds. So says a three-person team of Stanford and UC-Santa Cruz researchers. They produced a provocative ...

During Super Bowl 59, tails added to its advantage as the Chiefs won the toss in calling tails. Based on a simulation of 56 coin tosses 100,000 times, a single side would be expected to win ...

Humans’ closest primate relatives lost their tails about 25 million years ago, but exactly how has remained a mystery. A breakthrough in genetic research may finally offer answers.

The tails are associated with spina bifida, a dangerous condition in which the canals of the spinal cord don’t entire close before birth, but they are often present without the disorder.

A genetic parasite may have robbed humans and other apes of their tails. Around 25 million years ago, this parasite, a small stretch of repetitive DNA called an Alu element, ended up in a gene ...

Small reptiles like lizards and geckos are known for their extraordinary ability to regrow their tails, a potentially lifesaving skill in the wild. But it turns out these reptiles are not the only ...

Geckos are able to regrow their tails by activating a specific group of stem cells when the tail is lost. Scientists think this could help us find better ways to heal spinal cord injuries.

How humans lost their tails — and why the discovery took 2.5 years to publish An elegant run of experiments in mice reveals the genetic changes that led humanity’s ape ancestors to lose the ...
