The language was transmitted by our male ancestors, according to a study by the University of Cambridge (United Kingdom). Using genetic markers, scientists have found that the discovery applies to both the Scandinavian Vikings who reached Britain and the African or Polynesian tribes.
Are you lazy to play sports? Is it hard for you to get up from the couch to go to the gym? You may have lost two key genes, according to a study from McMaster University (Canada). To reach this conclusion, the researchers worked with mice, some of which lacked two muscle genes that control the AMPK protein, which is activated when we exercise.
In one in every 2,000 people, there is a duplicated region of chromosome 16 that makes men 23 times more likely to be extremely thin, a new study reveals. In the case of women, the predisposition is "only" five times greater than that of the rest of the population.
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.
The so-called "father of genetics", Gregor Mendel, is famous for his experiments with peas published in 1865 and 1866. Thanks to them, this Austrian monk and naturalist laid the foundations of genetics, becoming a basic figure in the history of the science. What did these experiments consist of?
A team of researchers from Duke University Medical Center and the University of Melbourne has found that addictive drugs like cocaine or heroin activate the same nerve cells and brain connections as a strong ancestral instinct: the appetite for salt.
Doron Lancet and his colleagues at the Weizmann Institute (Israel) conducted a study in which they analyzed the ability of different subjects to detect odors such as the scent of eucalyptus, spearmint, banana or sweat. In this way, they identified a gene, OR11H7P, associated with the perception of the smell of sweat.
From now on you will no longer be able to lie about your age. Scientists from the University of California (USA) have just developed a test that allows finding out how old you are from a simple sample of saliva, according to the magazine 'PLoS ONE'.
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.
