By applying some novel algorithms, computational techniques and the innovative programming language Unified Parallel C (UPC) to the cutting-edge de novo genome assembly tool Meraculous, a team of scientists simplified and sped up genome assembly, reducing a months-long process to mere minutes. This was primarily achieved by “parallelizing” the code to harness the processing power of supercomputers.
The Pentagon's Office of Force Readiness and Training recently teamed with Lockheed Martin and NSF to create a new platform for distributed, immersive training applications: Virtual World Framework. The platform makes it easier, faster, and less expensive to develop training games and simulations that can reach users around the world. The team demonstrated a prototype game designed to run on the platform: The Mars Game.
LANL researchers’ efforts to solve the complex problem of how ocean currents affect the infrastructure of floating oilrigs and their computational fluid dynamics numerical simulations has received recognition from ANSYS. Vortex-induced motion is a complex problem that occurs when there are highly turbulent flow and fluid-solid interaction phenomena. The available experimental data are very limited, especially from field measurements.
Planets tend to cool as they get older, but Saturn is hotter than astrophysicists say it should be without some additional energy source. The unexplained heat has caused a 2-billion-year discrepancy for computer models estimating Saturn’s age. Experiments at Sandia’s Z machine verified an 80-year-old untested proposition that molecular hydrogen, normally an insulator, becomes metallic if squeezed by enough pressure...
In response to public concerns about cryptographic security, the National Institute of Standards and Technology (NIST) has formally revised its recommended methods for generating random numbers, a crucial element in protecting private messages and other types of electronic data. The action implements changes to the methods that were proposed by NIST last year in a draft document issued for public comment.
As we entered our first week of summer, the week’s biggest hits included a strong bent toward several “lighter” mathematical topics: learning how math drives Formula 1 and launches Angry Birds, inspiring young minds at MoMATH, and Pi Day under attack. You also won’t want to miss molecules exhibiting strange, exotic states, hot lava flows on Venus, and some of the coolest experimental technology showcased at this year’s Paris Air Show.
Scientists have developed a computer model that clarifies the complex processes driving ocean mixing in the vast eddies that swirl across hundreds of miles of open ocean. The model is a first-of-its-kind tool because of its ability to exploit the power available from today’s supercomputers. Global climate simulations are beginning to be able to resolve the largest mesoscale eddies, which are considered the “weather” of the ocean.

Broad Institute is teaming up with Google Genomics to explore how to break down major technical barriers that increasingly hinder biomedical research by addressing the need for computing infrastructure to store and process enormous datasets, and by creating tools to analyze such data. As a first step, Broad Institute’s Genome Analysis Toolkit, GATK, will be offered as a service on the Google Cloud Platform, as part of Google Genomics.
As June 28, 2015, approaches, the Internet is once again anticipating controversy as the mathematical constant pi comes under threat from a group of detractors who will be marking "Tau Day." Tau Day’s revelers are campaigning for a constant twice as large as pi (about 6.28) to take its place, hence the June 28 celebration. Tau proponents say that, for many mathematical problems, tau makes more sense and makes calculations easier.
As the Atlantic hurricane season gets underway, communities in severe weather-prone regions are anxiously tracking pending storms and working to create effective disaster response plans. IBM, through an alliance with The Weather Company, has announced a new emergency management solution featuring sophisticated analytics and use of real-time weather data to help communities predict and plan for natural disasters far more accurately.
The idea of cloaking and rendering something invisible hit the small screen in 1966 when a Romulan Bird of Prey made an unseen, surprise attack on the Starship Enterprise. Not only did it make for a good storyline, it inspired budding scientists, offering a window of technology's potential. Today, pop culture has embraced the idea of hiding behind force fields, and mathematicians are looking at transforming science fiction into science.
A newly-designed material, which mimics the wing structure of owls, could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics.
Pope Francis' plea to make the state of the environment a central moral issue of our age has been greeted with applause from climate activists and a wide range of church, science and government leaders, but dismissive shrugs from those who doubt climate change. In "Laudato Si," Francis addressed "every living person on this planet," urging them to hear "both the cry of the Earth and the cry of the poor."
Tapping at mobile phone games, waking up to sunlight on a pleasant morning or watching a Formula One race — such experiences are at the heart of modern life, and mathematics is working behind the scenes on all of them. Math is also used in many disciplines — from economics to engineering, biology to geography. But many of us struggle with math, and find formulas and theories difficult to grasp. A free online course could help.
The top most-visited stories of the past week included an amazing image of Jupiter’s second largest moon, solving billions of equations in just minutes, relief and delight as Philae woke up, Einstein saving the Quantum Cat, a fundamental change in wireless communications, a 40-year-old algorithm problem put to rest, news that a black hole’s surface is no deadly firewall, and an applied mathematician’s theory on MA flight 370.
Researchers are using data mapping methods created to track the spread of information on social networks to trace its dissemination across a surprisingly different system: the human brain. The research team found that applying social network models to the brain reveals specific connections and nodes that may be responsible for higher forms of cognition.
My first impression upon entering the National Museum of Mathematics could be described as complete mathematical mayhem. Pre-teenagers were swarming dozens of exhibits in what seemed more like a huge play area than a museum dedicated to the study of an abstract science of numbers, quantity and shapes. However, as I waded in and began to understand specific exhibits, it quickly became obvious that this was a special place.
Throughout history, many revolutions have started with the desire for democracy, and the simulation revolution is no exception. Simulation is an effective way to test the design of a product virtually. It's now evolving into building simulation apps that can be shared across teams, departments and companies. Simulation apps can help organizations in every industry gain better R&D results, while saving both time and money.
Supercomputers have helped scientists find a surprising link between cross-shaped (or cruciform) pieces of DNA and human cancer. The study found that small DNA cruciforms are mutagenic, altering DNA in a way that can increase risk of cancer in yeast, monkeys and in humans. Researchers found short inverted repeats of 30 base pairs and under in a reference database of mutations in human cancer that are somatic, meaning not inherited.
Network scientists have developed a new computational method that can leverage any body of knowledge to aid in the complex human task of fact-checking. In multiple experiments, the automated system consistently matched the assessment of human fact-checkers in terms of their certitude about the accuracy of these statements.
For several years now, researchers have been investigating techniques for amplifying movements captured by video but indiscernible to the human eye. Earlier this month, they presented a new version of the algorithm that can amplify small motions even when they’re contained within objects executing large motions.
Researchers have developed a new approach to studying the effect of multiple genetic variations on different traits. The new algorithm makes it possible to perform genetic analysis of up to 500,000 individuals — and many traits at the same time. Complex models that let you look at the combined action of many different variants have, until now, involved so much computation that it would take a year to run a single complex query.
