Added: 07.08.2020 7:53 | 1 views | 0 comments

Germany did not follow correct procedure in seeking the extradition, from Italy, of a rapist, named as Christian B., on a European Arrest Warrant, an EU court adviser has said. Christian B. is also wanted in connection with kidnapping Madeleine McCann, a British toddler, in Portugal in 2007. He has served most of his rape sentence in Germany and could soon go free. The EU court usually follows advisers' opinions.

A new analysis of ancient genomes suggests that different branches of the human family tree interbred multiple times, and that some humans carry DNA from an archaic, unknown ancestor.

Algorithm created by deep learning finds potential therapeutic targets throughout genome

A team of researchers have developed an algorithm through machine learning that helps predict sites of DNA methylation - a process that can change the activity of DNA without changing its overall structure - and could identify disease-causing mechanisms that would otherwise be missed by conventional screening methods.

Faster rates of evolution are linked to tiny genomes

Added: 06.08.2020 16:18 | 19 views | 0 comments

Inside every cell lies a genome - a full set of DNA that contains the instructions for building an organism. Across the biological world, genomes show a staggering diversity in size but scientists still don't fully understand why. Now, scientists have found a link between mutation rate - how quickly the DNA sequence changes - and genome size. Writing in Current Biology, the researchers reported that prokaryotes with higher mutation rates lose genes at a faster pace, and therefore have smaller genomes.

Molecular forces: The surprising stretching behavior of DNA

Added: 05.08.2020 15:20 | 18 views | 0 comments

Experiments with DNA molecules show that their mechanical properties are completely different from what those of macroscopic objects - and this has important consequences for biology and medicine. Scientists has now succeeded in explaining these properties in detail by combining ideas from civil engineering and physics.

A normal DNA repair process can become a major source of mutations in cancer

Added: 04.08.2020 19:20 | 12 views | 0 comments

The mechanism unveiled triggers a mutation fog, causing hundreds of mutations in each tumor, which spread through the genome of lung, head-and-neck and breast cancers. Researchers have identified the antiviral APOBEC3A enzyme as the major cause of this new type of hypermutation. Published in Nature Genetics, the study shows how the mutation fog process generates many oncogenic ''cancer driver'' mutations, thus accelerating tumour development.
