This perspective view in Noctis Labyrinthus was generated from the main camera’s stereo channels on ESA’s Mars Express. It shows the beautiful details of landslides in the steep-sided walls of the flat-topped graben in the foreground, and in the valley wa

Martian Labyrinth

January 28, 2016 8:55 am | by ESA | News | Comments

This block of Martian terrain, etched with an intricate pattern of landslides and wind-blown dunes, is a small segment of a vast labyrinth of valleys, fractures and plateaus. The region, Noctis Labyrinthus — the labyrinth of the night — lies on the western edge of Valles Marineris, the Grand Canyon of the Solar System. It is part of a complex feature whose origin lies in swelling of the crust owing to tectonic and volcanic activity.

Multi-purpose Optical Chips can be Programmed on Demand

January 28, 2016 8:38 am | by Universitat Politècnica de València | News | Comments

A revolution in microwave photonics is bringing us the first all-purpose programmable optical chips. Optical chips or processors are used in everything from biomedical devices to telecommunications networks. As it stands, each chip is custom designed for each new task, which keeps costs high and the sector fragmented. Researchers have designed a generic optical chip that can be programmed on demand to carry out any number of functions.

Beyond Chess: Computer Beats Human in Ancient Chinese Game of Go

January 27, 2016 4:27 pm | by Malcolm Ritter, AP Science Writer | News | Comments

A computer program has beaten a human champion at the ancient Chinese board game Go, marking a significant advance for development of artificial intelligence. The program had taught itself how to win, and its developers say its learning strategy may someday let computers help solve real-world problems like making medical diagnoses and pursuing scientific research. AlphaGo, defeated the European champion in all five games of a match.

Astrophysical Project Wins 80 Million Processor Hours on Nation's Fastest Supercomputer

January 27, 2016 4:19 pm | by John Greenwald, Princeton Plasma Physics Laboratory | News | Comments

DOE has awarded a total of 80 million processor hours on the fastest supercomputer in the nation to an astrophysical project based at the Princeton Plasma Physics Laboratory. The grants will enable researchers to study the dynamics of magnetic fields in the high-energy density plasmas that lasers create. Such plasmas can closely approximate those that occur in some astrophysical objects.

Titan Targets Tumors: Large Computational Gains in Radiation Therapy

January 27, 2016 2:29 pm | by Oak Ridge Leadership Computing Facility | News | Comments

Researchers are looking into replacing particle accelerators with high-powered lasers. The electromagnetic fields of the laser can accelerate ions in a very short time, thus effectively reducing the distance needed to accelerate the ions to therapeutic energies from several meters to a few micrometers. Bussmann aims for understanding and controlling this new method of particle acceleration to make it available for patient treatment.

This image features Cairo, in Egypt. The capital of Egypt, Cairo is one of the largest cities in Africa. It has existed for over 1,000 years on the same spot on the Nile River banks. Located in the northeastern part of the country, Cairo is the passage to the Nile delta. The Nile River is the father of African rivers and the longest river in the world. It is the cause of the strong contrasts we see in the image.

New Real-time Platform to Help Business Tap Full Potential of Big Data

January 27, 2016 11:51 am | by CORDIS | News | Comments

Researchers have constructed and tested an online platform that will enable businesses to more effectively process big data. The EU-funded JUNIPER project was launched in December 2012 to develop, test and evaluate prototype technologies that could aid big data analytical software applications. The results of the project could be of significant benefit to a number of sectors.

Algorithm Predicts Factors to Reprogram Cells, Regenerate Organs

January 27, 2016 11:28 am | by Duke-NUS Medical School | News | Comments

Researchers have developed an algorithm that can predict the factors required to convert one human cell type to another. These game-changing findings have significant implications for regenerative medicine and lay the groundwork for further research into cell reprogramming. The algorithm, called Mogrify, is able to predict the optimal set of cellular factors for any given conversion.

The Code Contributors: Still More Insights on Future-proofing Algorithmic Code with the NAG Library

January 26, 2016 4:16 pm | by NAG | Articles | Comments

The NAG Library is a set of mathematical and statistical algorithms used by thousands around the world for the solution of numerical problems. Every release has included numerical code contributed by “Code Contributors” who generously give their code to help others. This Q&A looks into the code contribution process by interviewing eight individuals who have contributed code in order to gain their insights into the activity.

World’s Greatest Literature Reveals Multifractals, Cascades of Consciousness

January 26, 2016 11:07 am | by Polish Academy of Sciences | News | Comments

Conan Doyle, Dickens and Shakespeare. Regardless of the language, some of the world’s greatest writers appear to be, in some respects, constructing fractals. Statistical analysis revealed something even more intriguing. The composition of works from within a particular genre was characterized by the exceptional dynamics of a cascading narrative structure. This turns out to be multifractal. That is, fractals of fractals are created.

Improving Precision of Turbulence Simulations

Turbulence makes life difficult for the designers of cars or aircrafts. It cannot be simulated with absolute precision. Albert Einstein grins impishly from a poster on the wall in Professor Oberlack‘s office. Perhaps the genius already knew decades ago that his thinking would lend wings to machine construction engineers and help them to solve apparently unsolvable problems involving aerodynamics.
