New Research on the Co-evolution of Bats and Moths

May 31st, 2009

Current understanding of the co-evolution* of bats and moths has been thrown into question following new research reported in Current Biology.
Dr James Windmill from the University of Bristol has shown how the Yellow Underwing moth changes its sensitivity to a bat’s calls when the moth is being chased. And in case there is another attack, […]

How butterflies got their spots: A ’supergene’ controls wing pattern diversity (PLoS Biology)

May 29th, 2009

Butterflies are known to employ some interesting convergent evolutionary tactics to survive - some non-poisonous species have similar wing patterns to those of noxious species that predators avoid. In a new study published online today in the open access journal PLoS Biology (see below), Mathieu Joron, Chris Jiggins, and colleagues investigate the underlying genetic mechanisms […]

I and the Bird #68 - Winter Doldrum Edition

May 24th, 2009

Welcome to the 68th Edition of I and the Bird! That is, if your flight over here wasn’t delayed by “inclement weather” - the polite euphemism we use for blinding snow squalls. It is the deep of winter, folks, and that means radical changes in the way we interact with our feathered friends.

Gone are the […]

Limits of Nanotechnology: The Molecular Motors!

May 22nd, 2009

On November 28, 2005 Dr. William A. Dembski wrote:
“Ask yourself, Why do biological systems exhibit molecular machines at the smallest level permissible by the properties of matter? “Evolution” provides less and less a convincing answer.”
Dr. Dembski linked then to Molecular Motors (9 Nov. 2005)
That reminded me of my previous posting to Dr. D.:
“Discover how researchers […]

Synthetic Biology: Its Promise And The Challenge

May 20th, 2009

Medical News TodayDate: 15 Apr 2008 - 4:00 PDT
Synthetic biology is a new area of biotechnology research that holds a great deal of promise and controversy. Using in-depth understanding of genomes, scientists are now designing and building DNA from scratch. The results are useful organisms that can efficiently produce advanced biofuels and medicines. Researchers in […]

Regeneration: Scientist regrow chicken wing

May 17th, 2009

Chop off a salamander’s leg and a brand new one will sprout in no time. But most animals have lost the ability to replace missing limbs. Now, a research team at the Salk Institute for Biological Studies has been able to regenerate a wing in a chick embryo - a species not known to be […]

Review: Approaches towards systems-network research

May 15th, 2009

Srinivasan et al. has come up with a nice review [ pdf: http://bib.oxfordjournals.org/cgi/reprint/bbm038v1 ] of approaches towards systems-network research using data from various high throughput techniques used in functional genomics.

clipped from bib.oxfordjournals.org
The collection of multiple genome-scale datasets is now routine, and the frontier of research in systems biology has shifted accordingly. […]

WARNING: This blog may make sudden stops

May 13th, 2009

In the last week I got accepted into seminary (as well as a partial scholarship — yeah!) Therefore, it is very likely that between my full-time job, two (sometimes three) part-time jobs, family, helping out at the church, and now seminary, it is very likely that there will be long breaks between posts.
