2:05 PM | Researchers break nano barrier to engineer the first protein microfiber
Researchers have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. For the first time, this achievement has been realized on the microscale - a leap of magnitude in size that presents significant new opportunities for using engineered protein fibers.

1:57 PM | Who put the "plastic" in plastic surgery?
"Plastic Surgery" is the hot topic of the day (especially as it relates to Renee Zellweger) and so the question arises as to what plastic is used in plastic surgery. The word "plastic" is an old word that is used in many diverse settings. In materials science, there is plastic deformation. You also have the macromolecules that are the subject of most of the posts on this blog and you have the surgery. It may be surprising, but these uses are all based on the same meaning that the word "plastic" […]

1:56 PM | I find this NYT article just a bit naive
Surely we don't need professors to tell us about hiding information from your colleagues at work: Knowledge-hiding in the workplace is common and takes different forms, some more harmful than others, according to new research by Catherine E. Connelly, an associate business professor at McMaster University in Hamilton, Ontario, and David Zweig, an associate management professor at the University of Toronto, Scarborough. Theirs was not a study of inadvertent communication failures.

12:30 PM | RF heating of magnetic nanoparticles improves the thawing of cryopreserved biomaterials
Successful techniques for cryopreserving bulk biomaterials and organ systems would transform current approaches to transplantation and regenerative medicine. However, while vitrified cryopreservation holds great promise, practical application has been limited to smaller systems (cells and thin tissues) due to diffusive heat and mass transfer limitations, which are typically manifested as devitrification and cracking failures during thaw. Now researchers leverage a clinically proven technology […]

12:26 PM | Poison Butterfly – The discovery of how a bacterial gene incorporated into the butterfly genome provides resistance to deadly cyanide poisoning
Image: Tiger swallowtail butterfly on wild lupin. Image uploaded to wiki media by Dr Gordon E. Robertson. With its tall spike covered in brightly coloured flowers, the garden lupin (Lupinus polyphyllus) is a perennial favourite in English gardens. However, although this plant is magnificent to look at, ingestion of even a small amount can be dangerous … Continue reading →

11:02 AM | Happy Mole Day from the CSN!
co-authors: Mimi Hang & Marco Torelli The word mole is one of those crazy words that have multiple meanings that can sometimes lead to confusion.  Perhaps your first thought after hearing the word is a cute little animal that burrows in the ground.  Or maybe your mind jumps to the small growths on your chin.  […]

10:32 AM | NASA to test emerging super-black nanotechnology on the International Space Station
An emerging super-black nanotechnology that is to be tested for the first time this fall on the International Space Station will be applied to a complex, 3-D component critical for suppressing stray light in a new, smaller, less-expensive solar coronagraph designed to ultimately fly on the orbiting outpost or as a hosted payload on a commercial satellite.

9:03 AM | Graphene-based biomimetic soft robotics platform
Among the various robotic actuation mechanisms driven by different stimuli, light-driven systems have garnered more and more attention due to their advantages in wireless/remote control, localized rather than whole-field driven capabilities, and electrical/mechanical decoupling. Inspired by the photothermal effect of graphene in biomedical applications, researchers have now demonstrated an easily fabricated and remote/wireless control light-driven approach to actuation mechanism based on […]

9:52 PM | Two ways to snoop on self-organizing molecules
A few short years ago, the idea of a practical manufacturing process based on getting molecules to organize themselves in useful nanoscale shapes seemed... well, cool, sure, but also a little fantastic. Now the day isn't far off when your cell phone may depend on it. Two recent papers emphasize the point by demonstrating complementary approaches to fine-tuning the key step: depositing thin films of a uniquely designed polymer on a template so that it self-assembles into neat, precise, even rows […]

3:04 PM | Synchronizing mitochondrial metabolism
Mitochondria are fidgeters. That’s what researchers discovered in a recent study. The organelles undergo waves in ATP production. Furthermore, the mitochondria, like synchronized dancers, work in a coordinated fashion. A team at the National Institute of Dental and Craniofacial Research report in a paper just out in the journal Cell Reports that mitochondria in the […]

2:37 PM | Keep Magic Beans in Fairy Tales
In what can only be a stunning upset to the diet and nutrition world, Dr. Oz’s green bean coffee extract was found to maybe, possibly, perhaps not work so well. And by that, I mean the only bit of research supporting his beans is being withdrawn by two of the authors. What’s more is the […]

2:20 PM | Fogs of War: the Chemical Weapons Podcast
Chemical weapons have played a chilling role in human history ever since they were first used in World War I.  As reports of more recent use continue to cycle through the news, we decided to take a deeper look.  We wanted to understand why chemical weapons were created in the first place, the ethical dilemmas inherent in their use, and the complicated process of getting rid of them. The story begins in Belgium, where reporter Helena de Groot visits a farm in Flanders Fields—the […]
