With President Obama announcing climate-support initiatives at the 2014 United Nations Climate Summit, the U.S. Department of Energy national laboratories are teaming with academia and the private sector to develop the most advanced climate and Earth system computer model yet created. For Los Alamos National Laboratory researchers, it is a welcome advance for an already vibrant high-performance computing community.
A computer model that accurately predicts how composite materials behave when damaged will make it easier to design lighter, more fuel-efficient aircraft. Innovative computer codes form the basis of a computer model that shows in unprecedented detail how an aircraft's composite wing, for instance, would behave if it suffered small-scale damage, such as a bird strike.
Physicist, string theorist and best-selling author Brian Greene will talk about the intersection of science, computing and society as he delivers the keynote address at SC14 this November. Described by The Washington Post as "the single best explainer of abstruse concepts in the world today," Brian Greene is one of the world's leading theoretical physicists and a brilliant, entertaining communicator of cutting-edge scientific concepts.
“Seeking educational curriculum researchers. Humans need not apply.” A Washington State University professor has figured out a dramatically easier and more cost-effective way to do research on science curriculum in the classroom — and it could include playing video games. Called “computational modeling,” it involves a computer “learning” student behavior and then “thinking” as students would.
Mathematics might be able to reduce the need for invasive biopsies in patients suffering kidney damage related to the autoimmune disease lupus. Researchers have developed a math model that can predict the progression from kidney inflammation to scarring in the kidney that current treatments cannot reverse.
Face recognition software measures various parameters in a mug shot, such as the distance between the person’s eyes, the height from lip to top of their nose and various other metrics and then compares it with photos of people in the database that have been tagged with a given name. Now, research looks to take that one step further in recognizing the emotion portrayed by a face.

StarDrop 5.5 is a suite of software for guiding decisions in drug discovery, helping project teams quickly identify high-quality compounds. It works by evaluating complex data, which is often uncertain because of experimental variability or predictive error.
MIT researchers have developed an algorithm for bounding that they’ve successfully implemented in a robotic cheetah — a sleek, four-legged assemblage of gears, batteries and electric motors that weighs about as much as its feline counterpart. The team recently took the robot for a test run, where it bounded across the grass at a steady clip. The researchers estimate the robot may eventually reach speeds of up to 30 mph.
The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum has been what’s called the “Copenhagen interpretation” — which holds that, in some sense, a single particle really is a wave, smeared out across the universe, which collapses into a determinate location only when observed.

Earth's protective but fragile ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported September 10, 2014, in a rare piece of good news about the health of the planet. Scientists said the development demonstrates that, when the world comes together, it can counteract a brewing ecological crisis.
New software launched by researchers at Birmingham City University aims to reduce the long periods of training and expensive equipment required to make music, while also giving musicians more intuitive control over the music that they produce. The developed software, showcased at the British Science Festival, trains computers to understand the language of musicians when applying effects to their music.
Some mysteries of science can only be explained on a nanometer scale — even smaller than a single strand of human DNA, which is about 2.5 nanometers wide. At this scale, scientists can investigate the structure and behavior of proteins that help our bodies fight infectious microbes, and even catch chemical reactions in action. To resolve these very fine details, they rely on synchrotron light sources like the ALS at Berkeley Lab.
Researchers at Washington University in St. Louis have developed algorithms to identify weak spots in tendons, muscles and bones prone to tearing or breaking. The technology one day may help pinpoint minor strains and tiny injuries in the body’s tissues long before bigger problems occur.
Both whales and dolphins have pelvic (hip) bones, evolutionary remnants from when their ancestors walked on land more than 40 million years ago. Common wisdom has long held that those bones are simply vestigial. But new research flies directly in the face of that assumption, finding that not only do those pelvic bones serve a purpose, but their size and possibly shape are influenced by the forces of sexual selection.
A laser-based instrument being developed for the International Space Station will provide a unique 3-D view of Earth’s forests, helping to fill in missing information about their role in the carbon cycle.
It may look like fresh blood and flow like fresh blood, but the longer blood is stored, the less it can carry oxygen into the tiny microcapillaries of the body. Using advanced optical techniques, the researchers measured the stiffness of the membrane surrounding red blood cells over time.
The Great Pacific Garbage Patch is an area of environmental concern between Hawaii and California where the ocean surface is marred by scattered pieces of plastic. Scientists believe the garbage patch is but one of at least five, each located in the center of large, circular ocean currents called gyres that suck in and trap floating debris.
Scientists have discovered and described a new supermassive dinosaur species with the most complete skeleton ever found of its type. At 85 feet (26 m) long and weighing about 65 tons (59,300 kg) in life, Dreadnoughtus schrani is the largest land animal for which a body mass can be accurately calculated.
What if the taxi-service app on your cellphone had a button on it that let you indicate that you were willing to share a ride with another passenger? How drastically could cab-sharing reduce traffic, fares, and carbon dioxide emissions? Authoritatively answering that question requires analyzing huge volumes of data, which hasn’t been computationally feasible with traditional methods.
University of Hawaii at Manoa astronomer R. Brent Tully has led an international team of astronomers in defining the contours of the immense supercluster of galaxies containing our own Milky Way. They have named the supercluster “Laniakea,” meaning “immense heaven” in Hawaiian.
Ion channels are involved in many physiological and pathophysiological processes throughout the human body. A young team of researchers investigated how ion flux through a voltage gated sodium ion channel works in detail. Since this process is incredibly fast, computer simulations were performed to visualize sodium flux "in slow motion."
