… must’ve told a bud who seems to have put it up here: One thing the ENCODE consortium drove home is that DNA acts like a Dynamic Random Access memory for methylation marks. That is to say, even though the DNA sequence isn’t changed, like computer RAM which isn’t physically removed, it’s electronic state can […]

From: Evolution: The Fossils Speak, but Hardly with One Voice 5. Far too much attention may be given to genes and DNA. So much current evolution thinking, including questionable fields like evolutionary psychology, depends on the alleged power of the gene. Does anyone remember that fellow who said in the early 90s that a CD […]

Friends write to say that Darwinian evolutionary biologist (retired) William B. Provine has written a book , The “Random Genetic Drift” Fallacy (2014): Much of my life has been devoted to the history of population genetics. My early book was my Ph.D. thesis still in print: The Origins of Theoretical Populations Genetics (1971, 2nd edition, […]

And too few corresponding insights? Asks an op-ed in The Scientist : I just finished reviewing another mitochondrial genome paper. These days, the mitochondrial genome review requests are arriving faster than I can turn them out. Indeed, in 2014 alone, more than a thousand new mitochondrial genome sequences were deposited in GenBank—an almost 15 percent […]

From ScienceDaily: A gene previously suspected of wielding the single greatest genetic influence on human obesity actually has nothing to do with body weight, according to a new study led by researchers at Harvard Medical School and Boston Children’s Hospital. The work not only overturns a major finding about the genetics of obesity but also […]

And textbook claims are incorrect, researcher says. From The Scientist : Mosaicism can result when a de novo mutation arises after an embryo is formed. Using newer, more sensitive sequencing technologies, researchers have recently begun to identify mosaic mutations. … Of these 107 mutations analyzed, seven (6.5 percent) were not detected in the parents’ germlines. […]

From Quanta Magazine: Genetically identical fruit flies raised under the same conditions are creating a biological map of what makes individuals unique. For scientists studying individual variation, one of the biggest open questions is why it exists. Is it helpful or harmful to the individual and the population? “We still know very little about the […]

Should know better. In an article defending consensus science, physicist Ethan Siegel opines, Think about evolution, for example. Many people still rally against it, claiming that it’s impossible. Yet evolution was the consensus position that led to the discovery of genetics, and genetics itself was the consensus that allowed us to discover DNA, the “code” […]

From ScienceDaily: When children are unmotivated at school, new research suggests their genes may be part of the equation. A study of more than 13,000 twins from six countries found that 40 to 50 percent of the differences in children’s motivation to learn could be explained by their genetic inheritance from their parents. The results […]

Blow us away. No, really, from ScienceDaily: Scientists studied proteins found in cells, known as histones, which are not part of the genetic code, but act as spools around which DNA is wound. Histones are known to control whether or not genes are switched on. Researchers found that naturally occurring changes to these proteins, which […]

They modulate gene expressions over cells’ lifetimes. From The Scientist : Not only do telomeres protect the ends of chromosomes, they also modulate gene expression over cells’ lifetimes. … New work led by Jerry W. Shay and Woodring Wright of the University of Texas Southwestern Medical Center in Dallas demonstrates that telomeres are more than […]

As in But what IS a gene? (At one time we knew. We were wrong. Honestly and stubbornly so). Philosopher (and photographer) Laszlo Bencze here: The notion of a gene seems to be becoming less and less useful with every discovery in genetics. Of course all (or practically all) of these discoveries are being made […]

At one time, everyone knew what a gene was. It was one of those little beads on our chromosomes that determined whether we would be tall or short, fat or thin, smart or stupid. Or else didn’t, if we favoured the “environment” hypothesis. The trouble is, in the age of genome mapping, ENCODE, epigenetics, it’s […]
