Chiral condensates in a magnetic field: Accepted!
by Marco Frasca in The Gauge Connection
As my readers could know, I have had a paper written in collaboration with Marco Ruggieri (see here). Marco is currently working at Yukawa Institute in Kyoto (Japan). The great news is that our paper has been accepted for publication on Physical Review D. I am really happy for this very good result of a [...]... Read more »

Calculating minimum energy urban layouts
by James Keirstead in James Keirstead.ca
Designing a new eco-city? Wondering if your master plan is ambitious enough or if you could go further? We have a new paper out describing how mixed-integer linear programming and Monte Carlo analysis can be used to calculate a minimum energy urban layout as a benchmark for evaluating master plans and policy options....

Social learning
by David Bradley in Sciencetext
Social networking sites, forums, blogs and wikis are increasingly open, readily available and user friendly and as such have become platforms for human interaction that can foster and promote the development of networks and learning communities. The great potential for unplanned interaction and serendipitous discovery through such tools also seems to have a synergistic effect [...]Post from: David Bradley's Sciencetext Tech TalkSocial learning ...

BIG Physics for small Science
by Paige Brown in From The Lab Bench
Metallic particles can be synthesized which are adequately small to be suspended in a liquid phase, where the particles exist on a size scale such that buoyancy in the medium and forces of gravity are balanced, and the particle solution, known as a colloid, is stable. In this state, these nanoparticles, named after their dimensions on the nanometer scale (1/billionth of a meter), will stay dispersed instead of precipitating out of solution. It might help to think of the similar way in which larg........ Read more »

that’s not what we meant by computer scientist
by Greg Fish in weird things
A while ago, there was some buzz on the pop sci circuit about scientists using machines to catch up with the constantly growing body of published papers and asking whether the machines could ever qualify as actual scientists proposing hypotheses of their own. Now there seems to be an affirmative answer since a robot- aided [...]... Read more »

Detecting shape-shifting computer viruses
by David Bradley in Sciencetext
Researchers at a software company which makes antivirus and security products have developed a computer tool that can create shape-shifting viruses that elude detection by commercial virus scanners. The aim of the research, published in the current issue of the International Journal of Multimedia Intelligence and Security, is to try to stay one step ahead [...]Post from: David Bradley's Sciencetext Tech TalkDetecting shape-shifting computer viruses ...

Are there Robots in your Backyard? Experts Give Urgent Warning about Spy Robots!
by Stuart Farrimond in Dr Stu's Science Blog
I can imagine what you’re thinking: In a fight between humans and robots, we would win hands-down – we can just pull their plug out! But robots have come a long way in recent years. Bill Gates recently said that we are standing at the dawn of a new era in robotics, likening this present … Continue reading »... Read more »

Forget passwords, tricky sums are more secure
by David Bradley in Sciencetext
Faster, more secure logins for multimedia sites might be possible thanks to a new approach to website and database security. Boolean logins would allow thousands if not millions of users to more quickly access the content to which they are entitled, such as music, video and images.

Of Chocolate and Human Factors

Go on and admit it, you have a terrible attention span. But it’s not all your fault.

Charge it up!
by Cherish The Scientist in Engineer Blogs
Last week, on April Fools’ Day no less, I was informed that a book chapter I’d written last year had finally been published online. The article is about electrostatic discharge (ESD) and how it impacts a particular class of RFID tags. While I’ve gotten pretty comfy dealing with RFID, at least the ultra-high frequency (UHF) variety, I am actually far more interested in ESD as area of study. The physics of ESD is fascinating, primarily because it’s so difficult to get........ Read more »

Recently, the New York Times’s blog dealing with health and medicine, Well, featured an interesting piece on Desktop medicine. The author Pauline W. Chen, M.D., maintains that medical profession has been profoundly changed by the advent of desktop computers. In the past, doctoring was all about « sitting at patients’ bedside ». Today, it’s basically about staring [...]... Read more »

Circular logic is the best type of logic because it’s circular
by Duncan Hull in O'Really?
One of the great things about logic is there are so many different flavours to choose from. If you thought that logic came in just one flavour (vanilla), then think again. Now, I Am Not A Logician but I can’t help but marvel at the bewildering array of logical flavours on offer including, but not limited [...]... Read more »

Tip of the Week: MetaPhoOrs, orthology and paralogy predictions
The researchers and developers at PhylomeDB haven’t rested on their laurels. I did a tip of the week on PhylomeDB 3 months ago and not too long ago I was checking over there and found the team had created another useful database and analysis tool, MetaPhoOrs. What is MetaPhoOrs? To quote from the homepage:
MetaPhOrs is a public repository of phylogeny-based orthology and paralogy predictions that were computed using resources available in seven popular homology prediction services (Phylome........ Read more »

CUDA: Upgrading to 3 Tflops
by Marco Frasca in The Gauge Connection
When I was a graduate student I heard a lot about the wonderful performances of a Cray-1 parallel computer and the promises to explore unknown fields of knowledge with this unleashed power. This admirable machine reached a peak of 250 Mflops. Its near parent, Cray-2, performed at 1700 Mflops and for scientists this was indeed [...]... Read more »

When Reason Falters, It's Age-Morphing Apps and Virtual Reality to the Rescue
