Bio-heat transfer simulation of retinal laser irradiation
by Arunn in nOnoScience (a.k.a. Unruled Notebook)
From 2008, we have been investigating the effects of (human) retinal laser irradiation, a specific project of the general bio-thermo-fluids problem of laser interaction with tissues irrigated by blood flow. The work was done with suitable and timely input from (Dr. Lingam Gopal, then Chairman of) the research division of Shankar Nethralaya, a Chennai-based leading [...]... Read more »

Plant with anti-intoxication properties now found to reduce alcoholism
by Char in Basal Science (BS) Clarified
Researchers at the University of California have isolated a flavonoid from the plant Hovenia Dulcis that can counter the effects of alcohol, relieve symptoms of hangover, and is shown to be a likely cure for alcohol withdrawal and dependence (Shen et al., 2012). The plant Hovenia Dulcis, also known as the oriental raisin tree, has [...]... Read more »

Exome-based Copy Number Analysis with VarScan 2
by Daniel Koboldt in Massgenomics
Now online at Genome Research is the publication of VarScan 2, our in-house algorithm for simultaneous detection of somatic mutations and copy number alterations using exome sequence data from matched tumor-normal pairs. There are a number of reasons why exome-based copy number alteration (CNA) detection should not work. The hybridization process introduces biases, both between [...]... Read more »

A Case for Oral Diagnostics with Microfluidics
by Hector Munoz in Microfluidic Future
What’s So Great About Oral Diagnostics?
Well, a lot of things, but let’s start with the basics. In order to use a microfluidic device, you need some type of fluid right? Sure if you had some powder or fine material you could suspend it in a fluid, but for simplicity sake, let’s look at fluids as our test material. If you wanted to run a health-related diagnostic, you only have so many bodily fluids available before you have to get creative and very invasive:
Blood
Urine
Saliva
Sweat
Mucus
Tears
Out of all those fluids, blood (or serum) has been the preferred liquid. It is extremely rich in information and can expose a lot about a systemic condition or report on ailments located deep within the body. You have to filter it if you don’t want the blood cells in your sample, but it’s just a needle prick away. Other ‘fluids’ like mucus or saliva require a bit more work because of how thick and viscous they are, plus you need to filter out the debris floating around in your mouth. If blood is so great, why do we need anything else? Although blood is a great global fluid, sometimes you can get more detailed information by going closer to the source of the problem and choosing a more local fluid, but perhaps one of the greatest reasons is because the process to obtain the blood is still invasive. In the ideal microfluidics world of the future, we would need very small sample sizes and pin pricks wouldn’t be that bad. For now, spitting into a cup is still easier than and more enjoyable than getting stuck. Plus, exposed blood is always a health concern, and should definitely be avoided if possible.... Read more »

An X-ray laser—sounds cool, but what is it?

You may have noticed there was a lot of coverage on lasers last week. Some of the headlines really caught my attention: “X-Ray Laser Turns Up the Heat to 3.6 Million Degrees” or “World’s Most Powerful X-Ray Laser Super-Heats Aluminum Foil to 3.6 Million Degrees”. Sounds like an impressive laser, right? I wondered what an [...]... 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 manufacture at smaller, micro and nano levels. If you want to learn more about this topic, you should check out the Biomimetic Microsystems Platform at the Wyss Institute. Today I’d like to share biomimetic microfluidic research that mimics the silk-spinning process of spiders from Korea University.... Read more »

The Current State of dbSNP
by Daniel Koboldt in Massgenomics
Less than a decade ago, the leading experts estimated that there were approximately 10 million SNPs in the human genome. Those were the early days of post-genome research, when “The SNP Consortium” was formed and began BAC overlap comparisons to routinely identify and report SNPs. Believe it or not, in my old lab there were [...]... Read more »

Copyright Talk: The RIAA Bites the Hand That Feeds

The perpetrators seem to be the RIAA's best friends. They just haven't have realized it yet. This should be motivation enough for the RIAA's to halt their lobbying, at least until they learn to read.

A Glow-in-the-Dark Material that Lasts All Night and Longer
by Char in Basal Science (BS) Clarified
Remember those glow-in-the-dark stickers you had when you were a kid? They had to be “charged” in sunlight all day and would only glow for maybe 1 or 2 hours at the most. A research group at the University of Georgia has created a persistent phosphorescence material (i.e. glow-in-the-dark material) that has an afterglow (i.e. the glow in glow-in-the-dark) for more than 2 weeks after exposure to sunlight for only a few seconds to minutes. Moreover the afterglow emitted is designed so that it can only be seen with night vision goggle, making for some interesting applications.... Read more »
