In addition to the dog and the cat, man has had another inseparable companion for the last thousands of years: the pig. An international team of researchers from China, the United Kingdom and the United States has analyzed the DNA of this pet to reconstruct its history.
Researchers at the University of Newcastle, in the United Kingdom, have developed a pioneering fertility technique that allows embryos to be obtained from the DNA of one man and two women. This advance could help mothers with certain genetic disorders to have healthy children.
The genome of the black truffle (Tuber melanosporum), an underground fungus highly valued for its culinary interest, which develops in symbiotic association with the roots of certain trees (especially holm oaks, oaks and hazelnuts), has just been sequenced at the Institute National Agronomic Research in Champenoux (France).
Genetic sequencing of mitochondrial DNA obtained from a finger bone found in a cave in Siberia has allowed scientists to identify a hitherto unknown type of hominin that lived in the mountains of Central Asia between 48,000 and 30,000 years ago.
Being a celebrity does not go much for him and what he wants is to continue investigating and getting excited every time he comes across a finding that contradicts the budget. But a quarter of a century ago fate would have this professor of genetics at the University of Leicester, in England, discover by chance the gene fingerprint, the test that allows us to distinguish between two people based on their DNA. Jeffreys reviews the significance of his find with journalist Patricia Luna.
At the molecular level we are very simple, since all living beings that populate the Earth are made up of a small number of molecules. In fact, living matter consists mainly of long molecules in which a certain pattern repeats itself over and over again, sometimes with small variations. In addition, some of them fold in an elaborate, complex and extremely precise way. This is the case with DNA.
Not all of us age at the same rate as time progresses. The rate of physiological wear and tear and biological age (different from the chronological one shown by our DNI) depend to a great extent on a sequence of genes, as a team of British scientists has just demonstrated. Details are published in the journal Nature Genetics.
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.
