Modern genetics sheds new light on these ancient religious wars.
They were cuter and silkier... but less adapted to a harsh environment.
The first humans to reach the Americas came from Siberia in a single group some 23,000 years ago, at the height of the last Ice Age, says the new study. On their way to Alaska, they hanged around in the northern regions for a few thousands of years before moving deeper into North and South America.
According to an unusual study conducted by University of Vermont researchers, people with blue eyes may be more likely to become alcoholics – and researchers are trying to figure out why. Human eye color is a pretty strange thing – it’s an inherited trait influenced by more than one gene. These genes cause small changes […]
You may look more like your mom or more like your dad, but technically, you inherit equal amounts of genetic information from both; however, a new study has shown that you (and all mammals for that matter) are genetically more like their dads. If that sounds a bit confusing... well, it is. Specifically, although we inherit equal amounts of genetic mutations from both our parents, the mutations that make us who we are and not some other person actually 'use' more of the DNA that we inherit from our dads.
It’s one of the most remarkable adaptations in the animal world – growing a tail or a limb. Some lizards do it, salamanders do it, and by learning how they do it, we may soon be able to do it as well; with technology, that is. A team of researchers have discovered the genetic “recipe” for […]
An extremely challenging study published by a team of researchers from the Stanford School of Medicine claims that through some unknown mechanism mammals can bias the sex of their offspring in order to win the genetic lottery and produce extra grandchildren. The holy graal of modern evolutionary biology After analyzing 90 years of breeding records […]
Europe’s largest minority group, the Romani people have migrated from northwestern India, a new genetic study shows. The Romani, also known as the Roma, or Romi (depending on the language) have been originally called “gypsies” in the 16th century, because of their widely spread origin and because they were thought to come from Egypt. However, […]
According to a new study conducted by Professor Gerald Crabtree, who heads a genetics laboratory at Stanford University in California, humans have peaked their intellectual capacities thousands of years ago, and now we are in a slow, but certain, state of decline. The provocative theory comes from one of the leading minds in genetics, and […]
Another breakthrough in biology and medicine was reported, as scientists were able, for the first time, to take skin cells from patients who had suffered heart failure and make them repair the cardiac muscle. The technique had been tested only on rats and it seemed decades could pass until it would become suitable for humans, […]
The ethical and moral aspects of using stem cells have been discussed a lot and it seems there is no good answer; genetic practically has no limit and since the discovery of DNA things have evolved very quickly. But the thing is that the moral aspects concerning it could be left unsolved and yet everybody […]
