In a new project dubbed AGORA, researchers are working to remove the discrepancies among different computer models of galaxy formation by comparing different codes against each other.
The project AGORA is the short form for Assembling Galaxies of Resolved Anatomy. “We investigate galaxy formation with high-resolution numerical simulations and compare the results across different platforms, and with observation,” Project AG........ Read more »

Tom van Hemert and Ray Hueting of the University of Twente’s MESA Institute for Nanotechnology have found a way to “plug” leakage current in transistors by “squeezing” the transistor with a piezoelectric material.... Read more »
You probably noticed a few things about TheEGG: a recent decrease in blog post frequency and an overall focus on the algorithmic lens — especially its view of biology. You might also be surprised by the lack of discussion of quantum information processing: the most successful on-going application of the algorithmic lens. I actually first […]... Read more »

I am a careful reader of scientific literature and an avid searcher for already published material in peer reviewed journals. Of course, arxiv is essential to accomplish this task and to satisfy my needs for reading. In these days, I am working on Dyson-Schwinger equations. I have written on this a paper (see here) a […]...

Informed consent has been a foundation of research, and especially genetics research, in that last few decades though it’s taken quite some time to right past wrongs. And with genomics research and personal genomics generating huge amounts of data, informed consent becomes both more important and more complex.

Humans have a visual bias: everything in vision seems easy and natural to us, and it can seem a bit of a mystery why computers are so bad at it. But there is a reason such a massive chunk (about 30%) of cortex is devoted to it. It’s really hard! To do everything that it […]... Read more »

At this time of year, people are fond of telling scary tales – generally involving ghosts, ghouls, and other frightening creatures. Neuroscientists have their own horror stories, however – more niche, perhaps, but no less terrifying. Picture the scene: a group of PhD students are gathered around a flickering MRI console.

Serious gaming is big business. Many organizations – companies, schools, NGO’s – use games for training purposes, to engage customers, to advertise and to simulate important and critical situations. It is likely that you have been playing a game that was designed with the purpose of teaching you something, getting you to drink more milk or training your cooperative skills.
