Four color problem, odd Goldbach conjecture, and the curse of computing

by Artem Kaznatcheev in Evolutionary Games Group

For over twenty-three hundred years, at least since the publication of Euclid’s Elements, the conjecture and proof of new theorems has been the sine qua non of mathematics. The method of proof is at “the heart of mathematics, the royal road to creating analytical tools and catalyzing growth” (Rav, 1999; pg 6). Proofs are not […]... Read more »

Riding Hexapod Walkers on Dusty Alien Worlds

by Jason Carr in Wired Cosmos

Speculative fiction is the home of countless machines that fly in space, yet resemble humanoid lifeforms. Scientists are now working on the next generation of robots that will blaze a trail in space by going where humans simply can’t maneuver on their own. Like so many things in the field of space exploration, the descendents … Read More →... Read more »

A Quantum Version of Google

by Carian Thus in United Academics

A team of computer scientists in Spain applied a quantum PageRank algorithm to a network with 7 webpages. They found that the quantum PageRank sometimes ordered the webpages differently in terms of importance, but averaging the quantum PageRank score over time recovered the classical ordering....

Reflections on WebSci‘13

by Peter Kraker in Science and the Web

I spent last week at Web Science 2013 in Paris. And what a well spent time that was. Web Science was for sure the most diverse conference I have ever attended. One of the reasons for this diversity is that Webscience was collocated with CHI (Human-Computer-Interaction) and Hypertext. But most importantly, the community of Webscience …Read More...

More Than a Good Eye: Carnegie Mellon Robot Uses Arms, Location and More To Discover Objects

by Perikis Livas in Chilon

A robot can struggle to discover objects in its surroundings when it relies on computer vision alone. But by taking advantage of all of the information available to it – an object’s location, size, shape and even whether it can be lifted – a robot can continually discover and refine its understanding of objects, say researchers at Carnegie Mellon University’s Robotics Institute....

Social learning dilemma

by Artem Kaznatcheev in Evolutionary Games Group

Last week, my father sent me a link to the 100 top-ranked specialties in the sciences and social sciences. The Web of Knowledge report considered 10 broad areas[1] of natural and social science, and for each one listed 10 research fronts that they consider as the key fields to watch in 2013 and are “hot [...]...

Microwave for breast imaging?

by Know Your Images in Know Your Images

When we hear the word microwave, we immediately think about the heating device we have in our kitchen. But the word microwave just means waves with wavelengths from ranging from 1 meter to 1 millimeter (corresponding frequencies are 300MHz to 300 GHz). Microwave technology has been used in several engineering fields, and biomedical engineering is no exception. Microwave technology is used in the Radio Frequency components for MRI, but it also can be used as an imaging modality of its own. Microwave Imaging is research in progress, but there have been a number of groups working on this, which makes me believe that this will be available soon.... Read more »

Zinc: The Perfect Material for Bioabsorbable Stents?

by Perikis Livas in Chilon

In 2012, more than 3 million people had stents inserted in their coronary arteries. These tiny mesh tubes prop open blood vessels healing from procedures like a balloon angioplasty, which widens arteries blocked by clots or plaque deposits. After about six months, most damaged arteries are healed and stay open on their own. The stent, however, is there for a lifetime.... Read more »

UF researchers develop ‘nanotrain’ for targeted cancer drug transport

by Perikis Livas in Chilon

University of Florida researchers have developed a “DNA nanotrain” that fast-tracks its payload of cancer-fighting drugs and bioimaging agents to tumor cells deep within the body. The nanotrain’s ability to cost-effectively deliver high doses of drugs to precisely targeted cancers and other medical maladies without leaving behind toxic nano-clutter has been the elusive Holy Grail for scientists studying the teeny-tiny world of DNA nanotechnology....

Dissecting Art, Intersecting Anatomy - Medical illustration

by Know Your Images in Know Your Images

Pauline Lariviere was an artist whose main contributions were made to the field of medical illustration. As a scientist in the medical field, medical illustrations are essential to education. I have already spent some hours drawing something in the computer for a paper or presentation. In old times, all illustrations were done by hand, but nowadays computers play an important role and medical images are often used as a basis to medical illustrations. Here is an example of a medical illustration based on a CT scan:The video is about an exhibition which pays a tribute to Pauline Lariviere.

Evolution Doesn’t Need Competition, After All

It’s been taken for granted since Darwin; species evolve through competition with each other for scarce resources. Then, the “more fit” adaptations can reproduce and propel the evolutionary process that much further.... Read more »
