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:

Neil harbisson, the world's first cyborg.
by Jaime Menchen in United Academics
Neil Harbisson, aged 29, considers himself a cyborg. Affected from birth by achromatopsia, he is unable to perceive colours, just black and white. Since 2004, he wears an eyeborg, a device that allows him to recognize colours through sound waves... Read more »

An X-ray laser—sounds cool, but what is it?
by Cath in Basal Science (BS) Clarified
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 »

Watermarking molecules
by Aaron Sterling in Nanoexplanations

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 »

Quantum mechanics and the square root of Brownian motion
by Marco Frasca in The Gauge Connection
There is a very good reason why I was silent in the past days. The reason is that I was involved in one of the most difficult article to write down since I do research (and are more than twenty years now!). This paper arose during a very successful collaboration with two colleagues of mine: [...]... 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
by DJ Busby in Astronasty
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. In a business sense, for them to push the legislation of SOPA/PIPA seems ridiculous, given this context, doesn't it?... Read more »

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 ........ Read more »

can we explore space with unmanned drones?

Drone patrols are nothing new. By now, they're fairly humdrum stuff come to think of it. But what about a drone patrol on an alien world, one that could potentially last for decades and bring us a constant stream of data on everything we wanted to know about the world in question? Well, that's the [...]... Read more »
