Researchers from the University of Copenhagen found next to the skeleton of a boy between 12,600 and 13,000 years old, found in a cemetery in Montana (USA), a hundred tools covered with red ocher, typical of the Clovis culture, one of the Oldest Native American civilizations. The DNA sequencing of this skeleton has given the key to finally locate the origins of this hunter culture. The research has been published in the journal Nature.
Today a historical paleontological finding is published in the journal Nature. Collaboration between German and Spanish researchers has led to the sequencing of the oldest human genome found to date, dating back 400,000 years.
The venom of the king cobra can kill us, but properly treated it can also give us life, since its toxins act as inhibitors of neuronal communication and palliative of many diseases.
Genetics are essential in nature, however, although they share the same DNA, two twins are not exactly the same. Research that has just been published in the journal Science appears to have solved the mystery. Some regions of DNA that do not code for proteins but that decrease or increase the expression of genes are responsible for some features, such as the shape of the face.
Until now, most of the studies that analyzed the biological clocks of our body were based on hormones, telomeres or saliva. Now, at the University of California (UCLA) they have taken a further step in the world of gerontology, studying the way our DNA changes over time, a kind of biological clock inside our genes.
A study carried out by the Max Planck Institute in Cologne (Germany) has revealed that the way we age is conditioned by the DNA inherited from our mother and not only by our habits or way of life. This finding demonstrates that the dysfunctions that develop in our genome over time are not determinants of our longevity, and it lays the foundation for the development of palliatives for mutations transmitted through maternal inheritance.
A common plant in traditional Chinese medicine is highly harmful to health, according to a group of international researchers. Experiments have concluded that aristolochic acid, present in plants of the genus Aristolochia, damages DNA and causes kidney and liver cancer.
The fact that a teenager has certain genes in his DNA can make his academic results suffer, especially in four subjects: language, mathematics, science and history. This is the conclusion reached by scientists from Florida State University (USA) after comparing the average grades of a series of students and relating it to the variants of various genes (DAT1, DRD2 and DRD4) that are related to the synthesis of the dopamine, a neurotransmitter responsible for pleasant sensations and involved in the coordination of muscle movements, decision-making, learning and memory.
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.
