Is the age of the gene finally over?

If so, it’s remarkable outcome for genome mapping: So it has been dawning on us is that there is no prior plan or blueprint for development: Instructions are created on the hoof, far more intelligently than is possible from dumb DNA. That is why today’s molecular biologists are reporting “cognitive resources” in cells; “bio-information intelligence”; “cell […]

A complex network of genes helps plants cope with DNA damage

From ScienceDaily: When a building is damaged, a general contractor often oversees various subcontractors — framers, electricians, plumbers and drywall hangers — to ensure repairs are done in the correct order and on time. Similarly, when DNA is damaged, a molecular general contractor oversees a network of genetic subcontractors to ensure that the diverse cellular […]

Darwinsplaining the kids who get mitochondrial DNA from their dads

It was hardly heard of before and hardly widely predicted; now the Darwinian question is, why isn’t it more common? Why? Because there are two conflicting evolutionary forces at work. In the short-term, mixing mitochondria can be beneficial to individuals because the father’s mitochondria, say, can compensate for a harmful mutation in the mother’s mitochondria. […]

Gene that controls for animal size may have been identified

From ScienceDaily: The birder and biologist was Tom Smith, who has spent his career studying finches — specifically, black-bellied seedcrackers (Pyrenestes ostrinus) — in Cameroon and in his lab at the University of California-Los Angeles. He and his colleagues have spent years investigating why some of these finches have small beaks while others have large […]

Researcher shocked: Human mitochondrial DNA can be inherited from dads

Seventeen individuals from three unrelated multi-generation families have shown the trait (a high level of mtDNA heteroplasmy, ranging from 24 to 76 percent): A new study led by geneticist Taosheng Huang from the Cincinnati Children’s Hospital Medical Centre shows human mitochondrial DNA can be paternally inherited, in a landmark case that started with the treatment […]

'Junk DNA' Cell biology Genetics Intelligent Design

Wouldn’t you know, jumping “junk DNA” can be lethal too

Researchers Nigel Goldenfeld and Thomas Kuhlman noticed that “half of the human genome is made up of retrotransposons [jumping genes, “junk DNA”], but bacteria hardly have them at all” and wondered what would happen if they just inserted some: “We thought a really simple thing to try was to just take one (retrotransposon) out of […]

John Sanford gives lecture at NIH on mutations and human health

Geneticist John Sanford is also the author of Genetic Entropy: and one of the editors of Biological Information: New Perspectives: Proceedings of a Symposium Held May 31 Through June 3, 2011 at Cornell University Note: In a distinctly unsavoury move, devout Darwinians managed to get Biological Information dropped by Springer. It is all the more […]

Do we really live longer because of “longevity genes”? Researchers cast doubt

It’s now suggested that people likely to live long tend to find each other (assortative mating). How else to explain this?Researchers found that siblings’ and first cousins’ lifespans were well correlated but also: But spouses’ lifespans were correlated, too. That could be easily explained by spouses sharing the same household and lifestyle: eating the same […]
