Genomics

3D chimp and human genomes differ significantly

Some of us remember when we were 99% chimpanzee… But that is so last decade … This type of finding makes more sense. If we were really 99% genetically similar to chimpanzees, the logical deduction is that the genome doesn't tell us much about a life form. Would be nice if it did, right? Read More ›

Bacterium alters its genome to adapt to new conditions

Researchers: Achromatium is special in many respects: It is 30,000 times larger than its "normal" counterparts that live in water and owing to its calcite deposits it is visible to the naked eye. It has several hundred chromosomes, which are most likely not identical. This makes Achromatium the only known bacterium with several different genomes. Read More ›

“Genes within genes” may contribute to COVID-19’s pandemic potential

Researcher: "Missing overlapping genes puts us in peril of overlooking important aspects of viral biology," said Nelson. "In terms of genome size, SARS-CoV-2 and its relatives are among the longest RNA viruses that exist. They are thus perhaps more prone to 'genomic trickery' than other RNA viruses." Read More ›

There’s a new buzz on the block, “social genomics”

Erik Parens: They are unfailingly clear about the fact that, when they add up the tiny genetic effects, the aggregate is small compared with, say, the total effect of the environment. They are relentless in their rejection of genetic determinism, and vigorous in their reiteration that environments play a huge role in explaining the outcomes they study. Read More ›

Tuatara genome sequenced; some surprising findings

At Nature: The genome produced by Gemmell and co-workers is one of the largest vertebrate genomes published so far. At more than 5 gigabases, it is about 50% larger than the human genome… Tuatara have a close resemblance to their forebears from the early Mesozoic era, between 240 million and 230 million years ago… Read More ›

Devolution: The “surprising” gene costs of the carnivorous lifestyle to plants

Researchers: "To their surprise, the researchers discovered that the plants do not need a particularly large number of genes for carnivory. Instead, the three species studied are actually among the most gene-poor plants known. " Yes, because - as Mike Behe says - Darwin Devolves. Read More ›

Is biology “hiding its deepest mysteries”?

Physics was “hiding its deepest mysteries” thousands of years ago too before anyone uncovered laws for how it works. There are still mysteries in physics, of course, but they are now more basic. The laws are now known. Let's hope the same proves true for biology. Read More ›

Icelandic genome provides clues to Neanderthal history, creates puzzle

Puzzle: However, the researchers also found significant fragments of genetic material from another archaic species of human, Denisovans, in the DNA of the Icelanders, and this was something of a surprise. Up to now, Denisovan genes have primarily been found in Australian Aborigines, East Asians and people in Papua New Guinea. So how did these genes end up in Islanders' DNA? And when? Read More ›
