The Bulletin of the Atomic Scientists says Earth is now closer to human-caused doomsday than it has been in more than 30 years because of global warming and nuclear weaponry. But other experts say that's way too gloomy. The advocacy group, founded by the creators of the atomic bomb, moved their famed "Doomsday Clock" ahead two minutes on January 22, 2015. It said the world is now three minutes from a catastrophic midnight.
Just because concrete is the most widely used building material in human history doesn’t mean it can’t be improved. A recent study using DOE Office of Science supercomputers has led to a new way to predict concrete’s flow properties from simple measurements. The results should help accelerate the design of a new generation of high-performance and eco-friendly cement-based materials by reducing time and costs associated with R&D.
Optimization algorithms, which try to find the minimum values of mathematical functions, are everywhere in engineering. Among other things, they’re used to evaluate design tradeoffs, to assess control systems, and to find patterns in data. One way to solve a difficult optimization problem is to first reduce it to a related but much simpler problem, then gradually add complexity back in ...
NASA and Microsoft have teamed up to develop software called OnSight, a new technology that will enable scientists to work virtually on Mars using wearable technology called Microsoft HoloLens.

Is glass a true solid? Researchers have combined computer simulation and information theory, originally invented for telephone communication and cryptography, to answer this puzzling question. This puzzle of a material which seems solid to any observer while appearing fluid under the microscope is an old one. And, even with the help of today's supercomputers, it seems impossible to verify in simulations whether a glass ever stops flowing.

A.J. Jacobs wrote: “I think there's something to the idea that the divine dwells more easily in text than in images.” Since there has been an explosion in the amount of text, sacred and secular, available to anyone with an Internet connection, the need for processing tools has grown. Regular expressions can be used to extract specific text from documents due to their ability to replace many lines of code with as little as one line.
In the largest collaborative study of the brain to date, researchers from the Keck School of Medicine of the University of Southern California (USC) led a global consortium of 190 institutions to identify eight common genetic mutations that appear to age the brain an average of three years. The discovery could lead to targeted therapies and interventions for Alzheimer’s disease, autism and other neurological conditions.
A medical researcher has found the 2,500 year-old Pythagoras theorem could be the most effective way to identify the point at which a patient’s health begins to improve. The discovery was made after looking at data from ROC (Receiver Operating Characteristic) curves. These curves were initially developed during World War II for the analysis of signals to help operators decide whether a blip on the screen was an enemy target

Software that Knows the Risks: Planning Algorithms Evaluate Probability of Success, Suggest Low-risk AlternativesJanuary 16, 2015 1:57 pm | by Larry Hardesty, MIT | News | Comments
Imagine that you could tell your phone that you want to drive from your house in Boston to a hotel in upstate New York, that you want to stop for lunch at an Applebee’s around 12:30, and that you don’t want the trip to take more than four hours. Then imagine that your phone tells you that you have only a 66 percent chance of meeting those criteria — but that if you can wait until 1:00 for lunch, or if you’re willing to eat at TGI Friday...
For household robots to be practical, they need to be able to recognize the objects they’re supposed to manipulate. While object recognition is one of the most widely studied topics in AI, even the best detectors still fail much of the time. Researchers believe the robots should take advantage of their mobility, imaging objects from multiple perspectives. Matching up objects in the different images, however, poses computational challenges.

Wave equations help describe waves of light, sound and water as they occur in physics. Also known as partial differential equations, they have valuable potential for predicting weather or earthquakes, or certain types of natural disasters. Tao is interested in the theoretical side of these equations, seeking to discover with computer algorithms whether they can behave in a way that typically is the opposite of what occurs in the real world.
Topology, a branch of mathematics classifying geometric objects, has been exploited by physicists to predict and describe unusual quantum phases: the topological states of matter. These intriguing phases, generally accessible at very low temperature, exhibit unique conductivity properties, which are particularly robust against external perturbations, suggesting promising technological applications.

Using a new algorithm, researchers have calculated the average number of Likes artificial intelligence (AI) needs to draw personality inferences about you as accurately as your partner or parents.
This is not a text for the novice. However, for those math/statistics aficionados, there is much to be had. The book’s great strength lies in two areas: the first is Peter Congdon’s generation of an excellent bibliography of the most modern techniques available, and the other is his (slightly) more straightforward explanations of the strengths and weaknesses of these techniques and suggestions for optimizing the results.
In the coming year, while consumers will be treated to a dizzying array of augmented reality, wearables, and low-cost 3-D printers, computer researchers will be tackling the underlying technology issues that make such cutting-edge consumer electronics products possible.

By analyzing the light of hundreds of thousands of celestial objects, astronomers have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars, called diffuse interstellar bands. DIBs have been a mystery ever since they were discovered in 1922 — exactly which of the many thousands of possible molecules are responsible for these features?
The human lament that things in the past were much simpler is an accurate observation made from the perspective of riding along an exponentially increasing complexity curve. Examining the present or looking into the future can be a confusing torrent of concepts, vocabulary and technologies that appear to be spiraling out-of-control. At the First IEEE Integrated STEM Education Conference, Professor Steve Zilora reflected on this increase...
