I remember Craig Venter talking about synthetic life in the fall of 2007 with Carl Zimmer. Last summer he said that we’d have the first “synthetic species” by the end of the year. I haven’t heard about it in 2010, have you? Anyone have info on what’s going on here? No surprise that project deadlines…

Doberman Pinscher with OCD

In the wake of my post on selection and variation in dog skull shape, I thought it would be useful to point to this short paper, A canine chromosome 7 locus confers compulsive disorder susceptibility. Here’s the conclusion: The highly significant association of CCD with the CDH2 region on chromosome 7 is the first genetic…

The Oscillator

Interesting new ScienceBlog, Oscillator. From the about page: A collection of notes, thoughts, and news about synthetic biology and biologically inspired engineering in principle and in practice.

Inferring deep history in genes

When Mendelism reemerged in the early 20th century to become what we term genetics no doubt the early practitioners of the nascent field would have been surprised to see where it went. The centrality of of DNA as the substrate which encodes genetic information in the 1950s opened up molecular biology and led to the…

Scientists of note now on ScienceBlogs

Pamela Ronald of Tommorow’s Table, author of Tomorrow’s Table: Organic Farming, Genetics, and the Future of Food. Additionally, David Sloan Wilson, has moved his blog to ScienceBlogs. It’s called Evolution for Everyone, after the book of the same name. You can read my review of his book here.

Lost World, 2009

The story about the giant rat discovered in an isolated crater in Papua New Guinea is fascinating. It’s kind of atypical in these days, but if you read through really old copies of National Geographic from the early 20th century it you observe that it occurred all the time back then. I would of course…

Alcohol’s Good for You? Some Scientists Doubt It: For some scientists, the question will not go away. No study, these critics say, has ever proved a causal relationship between moderate drinking and lower risk of death — only that the two often go together. It may be that moderate drinking is just something healthy people…

When I found out a while back that Jonah Lehrer‘s next book was titled How We Decide, I knew I was going to check it out. It’s no coincidence that I recently reviewed Predictably Irrational, I blog because I’m interested in reducing the human animal down its basic units of organization. Due to my disciplinary…

Low Vitamin D Causes Problems For Acutely Ill Patients: Dr Paul Lee, Professor John Eisman and Associate Professor Jackie Center, researchers at Sydney’s Garvan Institute of Medical Research, examined a cohort of 42 Intensive Care Unit (ICU) patients. Forty-five percent turned out to be Vitamin D deficient. … When the team correlated the Vitamin D…
