That your neighbor is friendly or that he barely manages to answer you with a grunt when you pass him in the elevator may have a genetic condition. Researchers at the University of Buffalo and the University of California, in the United States, have identified variants of the receptors of two hormones that push certain people to be charming and generous, while others conform selfishly.
Do you think you are smarter than others? Genes are responsible for only part of intelligence, the rest is determined by different environmental factors. This has been shown by a long study carried out in Scotland that studied the intelligence of about 2,000 people throughout their lives.
An international DNA testing company, easyDNA, has announced the launch of a new paternity test that, unlike conventional tests, is performed before the birth of the child and also does not pose a risk to the health of mother and child.
The complete DNA sequence of a woman who lived 115 years has been deciphered by European scientists. The old woman was the oldest in the world at the time of her death, but she possessed the mind of someone several decades younger and no sign of insanity.
A study in which the Spanish National Research Council (CSIC) has participated has identified the oldest known non-coding DNA sequences, some of which are present in both humans and coral relatives. The comparison of the genomes of multiple animals, distributed by the branches of the tree of life, has revealed that not only the proteins that build us, but also some of the instructions on how and where to use them were present in our ancestors for more than 550 million years.
A NASA-funded study published in the journal PNAS suggests that the chemistry produced in comets and meteorites would have the ability to generate complex organic molecules that are part of DNA. It is not the first time that components of this type have been found, but the doubt about whether they came from contamination with terrestrial life, or had arisen in space, does not fit in the cases that have now been analyzed.
According to research by the University of Aberdeen in Scotland, there is a "genetic switch" in the DNA of Europeans that induces the consumption of foods rich in fat and alcoholic beverages.
A genetic study reveals that people with less academic qualifications age faster. The key is in the telomeres that cover the end of your DNA chromosomes, which are shorter in less educated people, an unequivocal sign of premature aging.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
