Patterned Hearts
by Perikis Livas in Tracing Knowledge
A team of bioengineers at Brigham and Women’s Hospital (BWH) is the first to report creating artificial heart tissue that closely mimics the functions of natural heart tissue through the use of human-based materials. Their work will advance how clinicians treat the damaging effects caused by heart disease, the leading cause of death in the United States.... Read more »

Nanomedicine: a new frontier
by Perikis Livas in Tracing Knowledge
Everything our bodies do depends on interactions that happen on a nanoscale, the realm of atoms and small molecules. Today, medicine is catching up.
At the University of Minnesota, nanomedicine researchers are pushing forward with projects like new drug-delivery technologies and better screening of potential drugs.... Read more »

Scientists Consider Ways to Improve the Negative Electrode in Li-Ion Batteries
by dailyfusion in The Daily Fusion
The National Institute for Material Science Global Research Center for Environment and Energy based on Nanomaterials Science (Japan) together with the researchers from the Tokyo Metropolitan University have successfully measured the volumetric expansion of single particles of silicon, which is a negative electrode material for lithium ion batteries, accompanying the charging reaction. Based on these results, scientists demonstrated the importance of the electrode design and are looking into the ........ Read more »

What does the Muse CD cover have to do with Medical Imaging?
by Know Your Images in Know Your Images
This is Muse CD cover of their 6th album: "The 2nd Law":Indeed, this image is truly beautiful and remarkable. It is an image of the white matter fibers in the brain obtained with diffusion MRI (link). The image was obtained by the Human Connectome Project, which is a 5-year project funded by NIH to find the networks of the human brain. These networks will show how our brain communicates between different regions and give insight about the anatomical and functional organization of the brain. The ........ Read more »

CT scans help Anthropology studies
by Know Your Images in Know Your Images
This video has caught my attention few days ago. Field Museum in Chicago has used a CT scan to help them with the face reconstruction of an ancient skull (12,000 to 15,000 year old). The great advantage of using a CT scan is that once you have scanned the skull, you can do the processing and reconstruction of the skull on a computer without having to touch it, which means that the skull is never damaged. The problem here is usually the transport of the skull to the CT scan, which are usually loc........ Read more »

Procrastination to find the most cited papers in Medical Imaging
by Know Your Images in Know Your Images
Few day ago, I was wondering what were the most cited (important?) papers in Medical Imaging in the last ten/five/two years. The problem was that I didn't know exactly how to find this information. I googled a bit around and I found a way and tried it out. I found also some extra information about the subject:Published Papers in Radiology, Nuclear Science and Medical Imaging Field: Citations in Radiology, Nuclear Science and Medical Imaging Field:It is interesting to note that it is increasing s........

Seeing Stars
by Perikis Livas in Tracing Knowledge
“WE’LL BE ABLE to see the beginning of the universe as we know it today,” says Charles Alcock, director of the Harvard-Smithsonian Center for Astrophysics (CfA) and professor of astronomy—imaging the radiation signatures from ancient galaxies billions of light years from his hilltop office on Garden Street, near the Radcliffe Quad. Addressing that same frontier, Abraham (Avi) Loeb, Baird professor of science and chair of the astronomy department, characterizes the researc........ Read more »

A news item over at Archaeology reports that a little wireless robot called Tlaloc II-TCwill soon “investigate the far reaches of a tunnel found beneath the Temple of the Plumed Serpent at Teotihuacan,” entering a chamber “estimated to be 2,000 years old, and [that] may have been used as a place for royal ceremonies or burials.”...

fMRI lie detection and the Semrau case
by Know Your Images in Know Your Images
Semrau is a psychologist accused of committing fraud to Medicare and Medicaid. The case became mostly famous, because he asked that fMRI lie detection would be a evidence in court. The judge had to decide if fMRI was admissible and after hearing scientists advocating for both sides, he has decided not to admit such evidence. However, the question is: Will it be possible to use fMRI lie detection one day?, because the reason for not admitting it has been based on the error rates and acceptance by........ Read more »

Connecting Form and Function: Serial Block-face EM
by TheCellularScale in The Cellular Scale
The retina is a beautiful and wondrous structure, and it has some really weird cells. Retina by Cajal (source)Retinal Ganglion Cells (RGC) have all sorts of differentiating characteristics. Some are directly sensitive to brightness (like rods and cones), while some are sensitive to the specific direction that a bar is traveling. I am discussing really amazing new techniques to see inside cells this month, and have already posted about the magic that is Array Tomography. Today we'll look at anoth........ Read more »

Will the droids take academic jobs?
by Artem Kaznatcheev in Evolutionary Games Group
As a researcher, one of the biggest challenges I face is keeping up with the scientific literature. This is further exasperated by working in several disciplines, and without a more senior advisor or formal training in most of them. The Evolutionary Game Theory Reading Group, and later this blog, started as an attempt to help [...]... Read more »

Mathematical Turing test: Readable proofs from your computer
by Artem Kaznatcheev in Evolutionary Games Group
We have previously discussed the finicky task of defining intelligence, but surely being able to do math qualifies? Even if the importance of mathematics in science is questioned by people as notable as E.O. Wilson, surely nobody questions it as an intelligent activity? Mathematical reasoning is not necessary for intelligence, but surely it is sufficient? [...]... Read more »
