How Many Ways Can You Arrange 128 Tennis Balls? Impossible Problem Solved

5 Stories You Shouldn’t Miss — January 29-February 4

February 5, 2016 1:33 pm | by Suzanne Tracy, Editor-in-Chief, Scientific Computing and HPC Source | News | Comments

Five must-read stories from the past week include the world’s smallest integrated optical switch, which operates at level of individual atoms; developing the technology needed to build next-gen HPC systems; an automatic bug-repair system that fixes 10x as many errors; cracking an infamous soviet cold war cipher; and solving the impossible problem of how many ways you can arrange 128 tennis balls.

An international team of researchers has revealed that, for many universal concepts, the world’s languages feature a common structure of semantic relatedness.

Semantically Speaking: Does Meaning Structure Unite Languages?

February 5, 2016 10:39 am | by Santa Fe Institute | News | Comments

We create words to label people, places, actions, thoughts and more, so we can express ourselves meaningfully to others. Do humans' shared cognitive abilities and dependence on languages naturally provide a universal means of organizing certain concepts? By measuring how closely words’ meanings are related within and between languages, researchers revealed the world’s languages feature a common structure of semantic relatedness.

Evolving our Way to Artificial Intelligence

February 5, 2016 9:57 am | by Arend Hintze, Michigan State University | Articles | Comments

Researchers designed a computer program capable of beating a top Go player — an important threshold in development of AI. It stresses once more that humans aren’t at the center of the universe, and human cognition isn’t the pinnacle of intelligence. As an AI researcher, I realize how impressive it is. Yet, it’s still not a big step toward the type of AI used by the thinking machines we see in movies. For that, we need new approaches.

The mathematical model was compared to experimental data for a wide-ranging set of tasks, from simple binary choices to multistep sequential decision making. It accurately captures behavioral choice probabilities and predicts choice reversal in an experim

Modeling How the Brain Makes Complex Decisions

February 5, 2016 9:37 am | by University of Cambridge | News | Comments

Researchers have constructed the first comprehensive model of how neurons in the brain behave when faced with a complex decision-making process, and how they adapt and learn from mistakes. The mathematical model is the first biologically realistic account of the process, and is able to predict not only behavior, but also neural activity.

Individual brain cells within a neural network are highlighted in this image obtained by CMU's Sandra Kuhlman using a fluorescent imaging technique.

Project Aims to Reverse-engineer Brain Algorithms, Make Computers Learn Like Humans

February 4, 2016 4:15 pm | by Byron Spice, Carnegie Mellon University | News | Comments

Carnegie Mellon University is embarking on a five-year, $12 million research effort to reverse-engineer the brain, seeking to unlock the secrets of neural circuitry and the brain’s learning methods. Researchers will use these insights to make computers think more like humans. The research project is funded by the Intelligence Advanced Research Projects Activity through its Machine Intelligence from Cortical Networks research program.

Planning for a Disease Outbreak? There’s a Game for That

February 4, 2016 3:27 pm | by Colorado State University | News | Comments

Computer scientists and statisticians at Colorado State University are turning disease outbreak planning exercises into a game. They’re creating powerful new software that can predict, simulate and analyze a major disease outbreak — all in the form of an intuitive, multiplayer game. Computer scientists are used to dealing with hundreds or thousands of variables and running what-if scenarios...

Giardia Protozoan Cyst

February 4, 2016 2:04 pm | by CDC | News | Comments

This digitally-colorized scanning electron micrograph depicts some of the ultrastructural morphologic details of an oblong-shaped Giardia protozoan cyst, revealing the filamentous nature of the cyst wall. Each cyst-wall filament is approximately 7-20 nm thick. Note that this cyst was undergoing "excystation," and was captured at a point in the process where a flagellated trophozoite was beginning to emerge from the right side of the cyst.

Low-power Chip Processes 3-D Camera Data, could help Visually Impaired

February 4, 2016 1:55 pm | by Larry Hardesty, MIT | News | Comments

MIT researchers have developed a low-power chip for processing 3-D camera data that could help visually impaired people navigate their environments. The chip consumes only one-thousandth as much power as a conventional computer processor executing the same algorithms. Using their chip, the researchers also built a prototype of a complete navigation system for the visually impaired.

Looking to Early-20th-century Radio Tech to Create Transmissions Impervious to Eavesdropping

February 4, 2016 12:27 pm | by Andrew Myers | News | Comments

Imagine communicating with your bank, the IRS or your doctor by way of an Internet that was perfectly secure. Your most private data would be protected with absolute certainty and, better yet, if any bad actor were to try to eavesdrop you would know immediately. Such is the promise of secure quantum communication. Researchers have created a novel quantum light source that might someday serve as the basis for quantum communication.

Cold War Russian Cipher may Finally be Solved

February 4, 2016 11:59 am | by Taylor & Francis | News | Comments

The Soviet VIC cipher used in the early 1950s, long known for being complex and secure, may not be as impossible to crack as initially assumed. Cracking the infamous Soviet VIC cipher is possible if one understands the enciphering algorithm. If one does not know the algorithm, the cipher indeed lives up to its reputation, and becomes nearly impossible to decipher.
