Watermarking molecules
by Aaron Sterling in Nanoexplanations
I’ve posted twice about Anonymous hacking into Stratfor — and, more generally, their hacktivism has been making bigger and bigger waves. CNN recently ran a fairly positive story on the support hacktivists are providing the Occupy movement. Many of these … Continue reading →... Read more »

Spin Silk Like a Spider! No Legs Required (Just Microfluidics)
by Hector Munoz in Microfluidic Future
Biomimetics. I love that word. Well, probably not as much as microfluidics, but it’s a close second. If you’re unfamiliar with the word, it basically refers to design that mimics biology. Biological systems have evolved into finely tuned machines, why not mimic them in order to synthesize what we need? Biomimetics isn’t new, it’s been around in one form or another for a long time (my favorite instance is Velcro), but our capabilities are broadening as we are able to manuf........ Read more »

How a cup of coffee a day may help to keep type 2 diabetes at bay.
by Michelle Clement in Crude Matter
Many of us, especially the current or former graduate students among us, are addicted to our breakfast caffeinated beverage of choice. Mine is tea, but if I had to guess, I’d wager that the most popular option is coffee. We chug it down in the morning to get ready for our day, we sip it thoughtfully at work, and we seek it out in the wee hours when we should be sleeping but instead we’re at the lab or at our desks, telling ourselves that we’ll run just one more gel or write jus........

Science that’ll warm your hands

After trying the hand-warmer my friend gave me for Christmas I thought, “cool, I wonder how this works?” Here’s the hand-warmer in action: So what’s going on? The hand-warmer heats up when you bend the metal disk that’s inside the pouch. Bending the disk causes the liquid inside the hand-warmer to solidify. This change [...]... Read more »

Unruly beasts in the jungle of molecular modeling
by The Curious Wavefunction in The Curious Wavefunction
The Journal of Computer-Aided Molecular Design is having a smorgasbord of accomplished modelers reflecting upon the state and future of modeling in drug discovery research and I would definitely recommend anyone - and especially experimentalists - interested in the role of modeling to take a look at the articles. Many of the articles are extremely thoughtful and balanced and take a hard look at the lack of rigorous studies and results in the field; if there was ever a need to make journal articl........

On reproducibility in modeling
by The Curious Wavefunction in The Curious Wavefunction
A recent issue of Science has an article discussing an issue that has been a constant headache for anyone involved with any kind of modeling in drug discovery - the lack of reproducibility in computational science. The author Roger Peng who is a biostatistician at Johns Hopkins talks about modeling standards in general but I think many of his caveats could apply to drug discovery modeling. The problem has been recognized for a few years now but there have been very few concerted efforts to addre........ Read more »

The Beethoven connection
by Joerg Heber in All that matters
Symphonies are some of the most complex musical pieces. They involve different instruments, each with their own unique sound, and each instruments section playing their own tunes. Yet, what are symphonies in comparison to the complexity of life? Proteins for example, they are made of a limited number of building blocks, amino acids, but take [...]... Read more »

Why drug design is like airplane design. And why it isn't.
by The Curious Wavefunction in The Curious Wavefunction
Air travel constitutes the safest mode of travel in the world today. What is even more impressive is the way airplanes are designed by modeling and simulation, sometimes before the actual prototype is built. In fact simulation has been a mainstay in the aeronautical industry for a long time and what seems like a tremendously complex interaction of metal, plastic and the unpredictable movements of air flow can now be reasonably captured in a computer model.In a recent paper, Walter Woltosz of Sim........

The Vasa Resurrected
by Dan Bailey in Smells Like Science
After the Vasa was salvaged from the bottom of Stockholm harbor nearly intact in 1961 and towed to a dry dock, archaeologists were some of the first people to board the resurrected ship. They squeezed through the Vasa’s cramped quarters and slogged through three-foot-deep mud on the lower decks, searching for artifacts. They quickly began to uncover thousands of objects: coins, bowls, cups, elegant furniture, a board game, a butter cask containing 333-year-old butter. Like a nautical Pompe........ Read more »

Two ways of looking at the same proteins: Insulin-like Growth Factor Binding Proteins
by Daniel in Ego sum Daniel
Back in June I blogged about a research paper that we had just published with myself as the lead author. The subject of our paper was the evolution of the Insulin-like Growth Factor Binding Proteins (IGFBPs), and how this family of proteins has expanded in vertebrate evolution. Yesterday I noticed that this paper, "my" paper!, now has received its very first citation! This was a my first paper as lead author, so naturally I avidly checked it out.
The research paper that cites us is in press ........ Read more »

Pills, thrills and polymorphs
by sciencebase in Sciencebase Science Blog
Almost any skilled organic chemist could create novel variations on the solid form, polymorphs, of small molecules currently used as pharmaceuticals. This represents a problem for manufacturers of generic drugs because big pharma attempts to extend the patent lifespan of its well-known products by adding such polymorphs to the patent.

Fifteen years of extensive scientific research reveals the best* curry house in Manchester!
by Duncan Hull in O'Really?
Curryology, the branch of science that deals with curry, is an established discipline with a long and distinguished history. The myriad ingredients of curry, such as curcumin (in turmeric), capsaicin (in chilli pepper), cumin, coriander and many others have been a topic of extensive scientific research [1,2,3,4,5].
Like many large British cities, Manchester is blessed with a large population of people from Bangladesh, India, Sri Lanka and Pakistan. All this means there is a bewildering array ........ Read more »

The future of computation in drug discovery
by The Curious Wavefunction in The Curious Wavefunction
Computational chemistry as an independent discipline has its roots in theoretical chemistry, itself an outgrowth of the revolutions in quantum mechanics in the 1920s and 30s. Theoretical and quantum chemistry advanced rapidly in the postwar era and led to many protocols for calculating molecular and electronic properties which became amenable to algorithmic implementation once computers came on the scene. Rapid growth in software and hardware in the 80s and 90s led to the transformation of theor........ Read more »
