Seeing Through the Skin

by Aurametrix team in Olfactics and Diagnostics

​Human skin emits light (albeit the glow is extremely weak) and a wide variety of small molecules that may be sometimes "sniffed" by dogs or even other humans. These chemicals tell a story about our health and wellness, things we eat and drink, touch and breathe. Mosquitoes use such emissions to assess our "attractiveness" from indicators such as Indoles (unpleasantly smelling but healthy "inner soil" biomarker) or carbon dioxide (amount of which correlates with the size of the person........

The Real Cost of Sequencing

by Daniel Koboldt in Massgenomics

The real cost of sequencing is as hard to pin down as a sumo wrestler. Working in a large-scale sequencing laboratory offers an interesting perspective on the duality of the so-called “cost per genome.” On one hand, we see certain equipment manufacturers and many people in the media tossing around claims that sequencing a genome […]...

A Universal Translator By Any Other Name…

by Mark E. Lasbury in The 'Scope

Star Trek wouldn’t have been possible without the universal translator. Who would want to watch a show where characters don’t understand each other – of course, that doesn’t stop people from watching political debates. The technology of a universal translator is easy, we have camera phones that will show you a foreign sign in your own language. It’s the software to decipher a previously unencountered language that’s proving tough to overcome. Are there any uni........ Read more »

Star Date: Pretty Darn Soon

by Mark E. Lasbury in The 'Scope

Star Trek celebrates its 50th anniversary in 2016. In preparation for the celebrations, we’re checking in on how close we are to making Star Trek technology a reality. The replicator made food and recycled trash, and later was used to make parts for the Enterprise. A machine fabricated what they needed on the spot. We have that now on the space station! Do you know how 3-D printing works and how we print parts, food, and even living tissue? Here’s how.... Read more »

ALMA Japan: Hi-Def Imaging of Spiral Gas Arms from Twin Baby Stars (w/video)

by DJ Busby in Astronasty

We know that about half the the stars out there (with sizes close to that of our sun) are binary systems. However, for a long time we've been lacking information on how they develop, since it's not been easy to get a whole lot of data from surrounding scattered mass that's so damned far away! Congrats to all involved!... Read more »

Collective Structures in Software Projects

by Jörg Friedrich in Software Engineering Economics

To understand the social dynamics of complex software development processes, it is necessary to analyze in which structures the persons involved and how this involvement affected their work. Damian Tamburri has in recent years identified the relevant social structures in a number of publications, analyzed and graded on their effect. He first distinguishes four basic […]... Read more »

A clever use of SciPy’s ndimage.generic_filter for n-dimensional image processing

by Juan Nunez-Iglesias in I Love Symposia!

This year I am privileged to be a mentor in the Google Summer of Code for the scikit-image project, as part of the Python Software Foundation organisation. Our student, Vighnesh Birodkar, recently came up with a clever use of SciPy’s ndimage.generic_filter that is certainly worth sharing widely.

Vighnesh is tasked with implementing region adjacency graphs and graph based methods for image segmentation. He initially wrote specific functions for 2D and 3D images, and I suggested that he s........ Read more »

The Curse of the Internet

by Aurametrix team in Health Technologies

It's hard to imagine our lives without the Internet  - either mobile or desktop. The Internet has become a catalyst of innovation, an essential tool in business and social life. It brought new levels of participation and access to knowledge. It enabled new forms of interaction, albeit mostly utilized for entertainment purposes. But despite all the advantages and conveniences, does the Internet really serve us or is it the other way around?... Read more »

TDD Improves Quality

by Greger Wikstrand in Greger Wikstrand

TDD Improves QualityTDD improves quality! That might sound obvious, but evidently it isn’t. Test driven development (TDD) is often cited as a key agile practice (1,2). But still, the evidence has been equivocal until now. What is TDD? If you already know what TDD is you should probably skip this section. If not, here is a super-brief […]From Greger Wikstrand - #agile, #projectmanagement, #ehealth, #mhealth #phr, #professionalism, #SoftwareEngineering by Greger Wikstrand .

Software through the lens of evolutionary biology

by Artem Kaznatcheev in Evolutionary Games Group

My preferred job title is ‘theorist’, but that is often too ambiguous in casual and non-academic conversation, so I often settle for ‘computer scientist’. Unfortunately, it seems that the overwhelming majority of people equate computer scientists to programmers or some general ‘tech person’, forgetting M.R. Fellows rallying cry: “Computer science is not about machines, in […]... Read more »

Can DNA Template Lead to Future Technologies?

by Jason Carr in Wired Cosmos

DNA is the blueprint for life. Could it also become the template for making a new generation of computer chips based not on silicon, but on an experimental material known as graphene? That’s the theory behind a process that Stanford chemical engineering professor Zhenan Bao reveals in Nature Communications (citation below). Bao and her co-authors, former post-doctoral fellows Anatoliy Sokolov … Read More →...

New Knowledge About Early Galaxies

The early galaxies of the universe were very different from today’s galaxies. Using new detailed studies carried out with the ESO Very Large Telescope and the Hubble Space Telescope, researchers, including members from the Niels Bohr Institute, have studied an early galaxy in unprecedented detail and determined a number of important properties such as size, … Read More →...

When it Smells Like Team Spirit

by Aurametrix team in Olfactics and Diagnostics

Why do we connect and collaborate, deciding to "walk in the light of creative altruism" instead of the "darkness of destructive selfishness"? Is it because of subtle behavioral clues that make us "click" and consider the other person a part of the group? Or is it because it smells like team spirit? It very well might be. We (literally) smell love, victory, fear, along with chemicals that motivate us to cooperate. As was recently shown in double-blind placebo-controlled studies that quantitativel........ Read more »

Researchers Turn a Smartphone into a Biosensor

by Jason Carr in Wired Cosmos

University of Illinois at Urbana-Champaign researchers have developed a cradle and app for the iPhone that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules. Having such sensitive biosensing capabilities in the field could enable on-the-spot tracking of groundwater contamination, combine the phone’s GPS … Read More →... Read more »
