Multiple Telescopes Reveal Striking Black Hole Action

November 25, 2015 11:33 am | by ESA | Comments

Scientists often use the combined power of multiple telescopes to reveal the secrets of the Universe — and this image is a prime example of when this technique is strikingly effective. The yellow-hued object at the center of the frame is an elliptical galaxy known as Hercules A, seen by the Earth-orbiting NASA/ESA Hubble Space Telescope. In normal light, an observer would only see this object floating in the inky blackness of space...

Katherine Johnson: The Girl Who Loved to Count

November 25, 2015 8:51 am | by NASA | Comments

“I counted everything. I counted the steps to the road, the steps up to church, the number of dishes and silverware I washed … anything that could be counted, I did.” So said Katherine Johnson, recipient of the 2015 National Medal of Freedom. Born in 1918 in the little town of White Sulfur Springs, WV, Johnson was a research mathematician, who by her own admission, was simply fascinated by numbers.

Brains behind the Wheel: Could Virtual Reality teach us to Avoid Real-life Accidents?

November 24, 2015 11:10 am | by The University of Nottingham | Comments

Scientists are exploring use of car driving simulators as tools for training and testing drivers in order to reduce road traffic accidents and fatalities. Research is looking at whether future interventions could prioritize use of driving simulators to make us safer at the wheel and our roads a safer place to be. To make this possible, it is important to understand if drivers behave comparably in simulated and real-world environments.

Metastasis in progress: The human circulatory system in many ways resembles an elaborate highway system. In the artist's rendering above, we get a sense of the roughly 100,000 mile length of an adult's system of blood vessels. In this maze, Professor Paul

Forecasting Metastatic Breast Cancer’s Path in a Patient

November 24, 2015 10:33 am | by University of Southern California | Comments

Researchers developed a mathematical model to forecast metastatic breast cancer survival using techniques usually reserved for weather prediction and financial forecasting. They looked at 25 years of data regarding 446 patients at Memorial Sloan Kettering and focused on a subgroup who were diagnosed with localized disease but later relapsed with metastatic disease. The model shows cancer metastasis is neither random nor unpredictable.

New Research Offers Quantum Leap for Long-distance Secure Communications

November 24, 2015 10:15 am | by University of Glasgow | Comments

A new telecommunications technique which harnesses quantum technology could lead to a much more secure form of worldwide internet communications. Researchers from the Universities of Glasgow, Stanford, Tokyo and Würzburg describe how they have implemented a novel tool for a long-distance telecommunication link which is impossible for hackers to breach. The technique could also underpin the creation of a new form of ‘quantum internet.’

Supercomputer Simulations Reveal Dynamics of Protein Motion, Function

November 23, 2015 2:42 pm | by Miki Nolin, Oak Ridge National Laboratory | Comments

Supercomputing simulations at ORNL could change how researchers understand the internal motions of proteins that play functional, structural and regulatory roles in all living organisms. Studying proteins — their structure and function — is essential to advancing understanding of biological systems relevant to different energy and medical sciences, from bioenergy research and subsurface biogeochemistry to drug design.

Computer Vision: Computers Perceive Image Curves like Artists

November 23, 2015 12:15 pm | by Umeå University | Comments

Imagine computers being able to understand paintings or paint abstract images much like humans. Bo Li demonstrates a breakthrough concept in the field of computer vision using curves and lines to represent image shapes and furthermore to recognize objects. Accurate modeling of image features is very important in a wide range of computer vision applications.

Mathematical Modeling Enables Biomedical Imaging at One-thousandth the Cost

November 23, 2015 11:00 am | by Larry Hardesty, MIT | Comments

MIT researchers have developed a biomedical imaging system that could ultimately replace a $100,000 piece of a lab equipment with components that cost just hundreds of dollars. The system uses a technique called fluorescence lifetime imaging, which has applications in DNA sequencing and cancer diagnosis, among other things. So, the new work could have implications for both biological research and clinical practice.
