Loops to tie a knot in proteins? - Code for life

Grant Jacobs Jul 30, 2010

Most proteins fold onto themselves without forming knots. A minority form a ’topologically entangled conformation’, a knot. Proteins are strings of amino acids, chained together one after the other. (Source: WIkimedia Commons.) The properties of proteins depends on their specific three-dimensional fold, how the chain of amino acids are arranged in … Read More

Honey’s anti-bacterial properties found? - Code for life

Grant Jacobs Jul 14, 2010

New research suggests that (some of) the secrets to honey’s anti-bacterial properties may have been revealed. A Dutch team of microbiologists propose that the anti-bacterial properties of the honey they tested come down to four chemicals and one general property: [caption id="attachment_3001" align="alignright" width="350" caption="Honey comb; near the top-right bees can be seen entering … Read More

Boney lumps, linkage analysis and whole genome sequencing - Code for life

Grant Jacobs Jul 06, 2010

We all have our lumps, the quirky features we develop with time. Some of these are bone spurs, extra growths of bone. These can be caused from damage to joints, like the lumpy joints seen in elderly people with arthritis. Bone spurs from differing causes can develop in many parts of the body, spine, … Read More

Autism genetics, how do you copy? - Code for life

Grant Jacobs Jun 10, 2010

Subtitle: Recent research identifies many changes in copy number that may point to genes that cause or are associated with autism. In order to verify that important information has been conveyed over radio, the sender might ask ’how do you copy’ or, more briefly, ’how copy’ asking the receiver to tell the sender the information they … Read More

If some of us have Neanderthal genes, are Neanderthals us? - The Atavism

David Winter Jun 08, 2010

I got a little bit starry eyed writing about the Neanderthal genome the other day. I chose to retrace the arc of scientific progress that links the initial description of Neanderthal man as something different than modern humans to the point reached l... Read More

I remember because my DNA was methylated - Code for life

Grant Jacobs May 29, 2010

Our memories keep our yesterdays, our friends’ faces, the distinctive smell of previous partners, if we’ve read that book before, what clothes you wore to the party. Movies and books have been written about memories. Or the trials not being able to keep them.2 Poets and lyricists evoke them, talk about them and reminiscence … Read More

Testing common ancestry to all modern-day life - Code for life

Grant Jacobs May 14, 2010

That evolution occurs is well resolved. Precisely how evolution occurs, in detail, is less so. One question revolves around if present-day life arose from a single species or more than one.
