Scientists have found the first step toward discovering the biochemistry that controls the switch from wakefulness to sleep. The first unbiased genetic screen for sleep defects in mice has resulted in two interesting mutants: Sleepy, which sleeps excessively, and Dreamless, which lacks rapid eye movement (REM) sleep.
For the first time, scientists have found a conclusive link between the "red hair" gene variant and a high mutational burden - which in this case, means a high number of mutagenic processes associated with skin cancer.
The surgery can be quite complicated because aside from removing excess fingers, the doctors also have to create opposable thumbs for Hong Hong as he was also born with no thumbs.
Most wild horses have lost their unique wild Dun coats that are characterized by pale hair and zebra-like dark stripes. In a recent study, researchers investigate the genetics behind this unique skin pigmentation and why horses have evolved differently.
Analyzing the body language of mice may help scientists better understand the behavioral effects of certain gene mutations.
Cheetahs migrated to Africa from North America 100,000 years ago during the last Ice Age. Following their "big move," populations dwindled and incestuous breeding increased. This troubled linage has had a lasting impact on modern Cheetahs, many of which have difficulty reproducing due to a gene mutation that affects sperm development.
Researchers from the University College London (UCL) have finally deciphered the recipe for painlessness with the help of genetically modified mice.
Biologists recently discovered skin proteins shared by humans and turtles which developed in a common ancestor roughly 310 million years ago.
A study on a breed of farmbirds known as Plymouth Rock chickens suggests evolutionary differences can be observed on a much shorter time scale than previously thought.
CRISPR, a gene-editing system, could have serious consequences if rapidly spreading genes end up in the wrong species.
A giant wolfish caught off the island of Hokkaido, near the Fukushima nuclear plant is raising concerns about how radiation contamination from the 2011 nuclear power plant accident has spread and the impact it's having on ecosystems and the evolution of nearby wildlife.
Giant pandas eat a lot, it's been established. New findings say they have low body heat, more so than any other black and white animal. Let's talk about the reasons for that.
Many humans are known for going on drunken binges, but wild chimpanzees may also be alcoholics, according to new research, which found the animals going out of their way to get drunk on palm wine in West Africa.
For the most part, evolution seems a lot like a lottery of mutations. The winners get to survive, reproduce, and eventually evolve. The losers disappear from all but the fossil record. Now new research has revealed that a small group of microbes and viruses are apparently cheating the system, systematically picking and choosing what mutates to help them live in some hostile environments.
When it comes to gender, birds really can have their cake and eat it too, but only at the cost of a very lonely life. That's at least according to new research on a "split-sex" cardinal discovered nearly six years ago - a bird that boasts both genders clearly on each side of its body, as represented by its stunning half-and-half plumage.
