Hunting for the finest droplet

11 hours 11 min ago
Modern passenger airplanes already consume less than three liters fuel per one hundred kilometers and passenger. Scientists are currently working on further improving this value. In addition, engineers plan to optimize the combustion process such that exhaust gas emission is reduced considerably. For this purpose, they use supercomputers and simulation methods that are usually applied for tsunami calculations or for water effects in computer games.

Virtual reality allows you to look inside your body and could help improve drug delivery

Tue, 11/21/2017 - 9:14am
Renderings of 3-D cells in the body are traditionally displayed using 2-D media, such as on a computer screen or paper; however, the advent of Virtual Reality (VR) headsets means it is now possible to visualize and interact with scientific data in a 3-D virtual world.

New way to write magnetic info could pave the way for hardware neural networks

Mon, 11/20/2017 - 11:15am
Researchers have shown how to write any magnetic pattern desired onto nanowires, which could help computers mimic how the brain processes information.

New computational method provides optimized design of wind up toys

Fri, 11/17/2017 - 11:17am
A team of leading computer scientists has developed a novel computational system to aid the design and fabrication of wind-up toys, focusing on automating the intricate interior machinery responsible for the toys' wind-up motion.

Computer program finds new uses for old drugs

Thu, 11/16/2017 - 11:21am
Researchers have developed a computer program to find new indications for old drugs. The computer program, called DrugPredict, matches existing data about FDA-approved drugs to diseases, and predicts potential drug efficacy. In a recent study, the researchers successfully translated DrugPredict results into the laboratory, and showed common pain medications -- like aspirin -- can kill patient-derived epithelial ovarian cancer cells.

What is the computational power of the universe?

Wed, 11/15/2017 - 12:36pm
Can a close look at the universe give us solutions to problems too difficult for a computer -- even if we built a computer larger than a planet? Physicist Stephen Jordan reflects on this question in a new NIST video, along with a scientific paper that considers one particular tough problem the universe might answer.

Multiplayer video games: Skill at game and intelligence linked

Wed, 11/15/2017 - 12:36pm
A link between young people's ability to perform well at two popular video games and high levels of intelligence has been uncovered.

Photomosaic technology finds order in chaos of coral reefs

Wed, 11/15/2017 - 7:49am
Scientists have created and analyzed detailed photomosaics of the coral reef at Palmyra Atoll using advanced imaging and digitization technology.

Speedy collision detector could make robots better human assistants

Tue, 11/14/2017 - 9:34am
A faster collision detection algorithm could enable robots to work more fluidly in the operating room or at home for assisted living. The algorithm, dubbed 'Fastron,' runs up to eight times faster than existing collision detection algorithms. It uses machine learning to help robots avoid moving objects and weave through complex, rapidly changing environments in real time.

Essential quantum computer component downsized by two orders of magnitude

Tue, 11/14/2017 - 7:48am
Qubits, the key building blocks at the heart of every quantum computer, are extremely sensitive to interference and need to be shielded from unwanted signals, for example by using so-called nonreciprocal devices. But until now these devices were huge and produced unwanted magnetic fields themselves. Now, scientists have developed a new nonreciprocal device that is only a tenth of a millimeter wide, and -- maybe even more importantly -- is not magnetic.

Quantum computing with molecules for a quicker search of unsorted databases

Tue, 11/14/2017 - 7:42am
Scrapbooks or social networks are collections of mostly unsorted data. The search for single elements in very large data volumes, i.e. for the needle in the data haystack, is extremely complex for classical computers. Scientists have now quantum mechanically implemented and successfully executed Grover's algorithm, a process for the quick finding of a search element in unsorted databases.

Bioengineered robotic hand with its own nervous system will sense touch

Tue, 11/14/2017 - 6:20am
Researchers are developing a first-of-its-kind bioengineered robotic hand that will actually feel and adapt to its environment. This “living” robot will have its own peripheral nervous system directly linking robotic sensors and actuators.

New technology makes artificial intelligence more private and portable

Tue, 11/14/2017 - 6:13am
Technology is paving the way for artificial intelligence (AI) to break free of the internet and cloud computing.

Supercomputing speeds up deep learning training

Mon, 11/13/2017 - 9:36am
Researchers used Stampede2 to complete a 100-epoch ImageNet deep neural network training in 11 minutes -- the fastest time recorded to date. Using 1600 Skylake processors they also bested Facebook's prior results by finishing a 90-epoch ImageNet training with ResNet-50 in 32 minutes. Given TACC's large user base and huge capacity, this capability will have a major impact across all fields of science.

Artificial intelligence tool quantifies power imbalance between female and male characters in Hollywood movies

Mon, 11/13/2017 - 9:36am
Researchers who used machine learning tools to analyze language in 800 Hollywood movie scripts found subtle but widespread gender bias in the amount of power and agency given to male and female characters.

Scalable clusters make HPC R&D easy as Raspberry Pi

Mon, 11/13/2017 - 9:36am
A quest to help the systems software community work on very large supercomputers without having to actually test on them has spawned an affordable, scalable system using thousands of inexpensive Raspberry Pi nodes.

Fruit fly brains inform search engines of the future

Thu, 11/09/2017 - 11:07am
The way fruit flies identify similarities between odors offers a new approach for search algorithms.

The next generation of power electronics? Gallium nitride doped with beryllium

Thu, 11/09/2017 - 10:12am
Physicists have made a breakthrough in revising methods largely discarded 15 years ago. They have discovered a microscopic mechanism that will allow gallium nitride semiconductors to be used in electronic devices that distribute large amounts of electric power.

First large-scale doxing study reveals motivations and targets for cyber bullying

Tue, 11/07/2017 - 9:29am
The first large-scale study of a low-tech, high-harm form of online harassment known as doxing, which involves collecting and publishing sensitive personal information to exact revenge, seek justice, or intimidate victims, revealed the primary motivations are revenge and justice. Researchers created a custom text classifier to sort through 1.7 million files. They found new abuse filters on Facebook and Instagram appear to be effective in making victims feel safer.
