A group of Andean ferns, believed to be an "old" plant species dating back to the age of the dinosaurs, relatively recently adapted to one of the Earth's most extreme environments, a new study says.
A native lizard species from Florida has demonstrated some rapid evolution - in as little as 15 years - due to pressures from an invading lizard species hailing from Cuba, according to a recent study.
A longstanding question among scientists is whether evolution is predictable, and they may have finally found their answer in two distinct species of squid. The genetic underpinning of bioluminescence, or the ability to emit light, in these cephalopods may in fact be surprisingly predictable, new research shows.
Went to one too many Guns N' Roses concerts in your youth? Having trouble hearing your friends and family as you age? Researchers are suggesting that you don't necessarily need to get a hearing aid. Experts may be able to simply restore your hearing, good as new.
About 385 million years ago, a pair of ancient Scottish fish did a jig that was somewhat like square dancing, and now scientists are saying this was actually the awkward origin of sex.
It just got a lot worse to be a frog living in Spain right now. Spanish frog species already combating the same deadly chytrid fungus that is wreaking havoc on amphibian populations all over the world now must also deal with a pair of lethal and fast-spreading viruses.
We all know that men are from Mars and women are from Venus, and a new study supporting this way of thinking shows that male brains - at least in nematodes - are wired to choose sex over food, whereas the same doesn't ring true for females.
Rock gobies are masters of camouflage, able to change both their color and brightness within a minute, new research shows.
A certain species of shark is hiding out in corals in an attempt to escape ocean acidification, according to a new study.
A fruit fly's sense of smell could potentially be used to sniff out bombs and drugs, according to a new study.
For geckos, climbing along walls and even upside down is a piece of cake, but going downhill, on the other hand, requires some effort, according to new research.
Huge, now extinct, kangaroos that roamed the Australian outback 100,000 years ago weren't hoppers, despite the popular connotation, but had bones made for walking instead, a new study shows.
The pesky house fly may be annoying, but this buzzing insect's genome could improve human health, according to a new study.
A new study has shown that the "love hormone" known as oxytocin may be the primary, if not sole, determinant of whether or not an animal feels sexual attraction towards a prospective mate. Interestingly, this only seems to hold true for females.
Anorexics may find help accepting food and body images from doses of oxytocin, a hormone commonly referred to as the "love hormone," according to two studies looking into the effects and possible applications of the hormone.
