New algorithm named Squirrel detects weaknesses in the power grid.  It can be applied to all types of hazards, including earthquake, malicious attack, and obstruction caused by squirrels.  What conditions and failures in the infrastructure of electric grids could lead to a dramatic blackout? And how private companies and government organizations could invest in to help ...

Researchers use brain-inspired methods to effectively detect the signals at the receiver’s end. It’s based on the Echo State Network that offers high performance while consuming less energy. Scientists are always seeking more efficient and more reliable communications, for everything from mobile phones and televisions to medical instruments and satellites. The technique that has been ...

New model examines how infectious seeds diffuse through the uneven structure of the brain. Researchers used MRI scans of an adult brain to create high-resolution simulations in both 2D and 3D.  These simulations recreate the pattern of damage observed in numerous neurodegenerative disorders.  Neurodegenerative diseases associated with age are multifaceted and complex pathologies. In most cases, their ...

Researchers want to blast holes in the clouds to transmit information at high rates.  To do this, they will use ultrashort high-intensity laser filaments.  The technology doesn’t leave any negative impact on the atmosphere.  Today’s long-range information is transmitted by either radio waves (via satellites) or underground optical fiber. However, the flow of information is ...

For the first time, researchers develop a technique to capture 3D images of microscopic cracks in nickel-base alloys caused by hydrogen or water exposure.  It will help engineer develop microstructures with extended material life, saving costs on repairs and replacements. Microfractures in metal alloys cannot be seen with the naked eye, but they can extend ...

New deep learning model analyzes breast tissues in mammograms and accurately estimates density ratings.  These ratings are an independent risk factor for breast cancer.  The model takes less than one second to process one mammogram and it could be easily scaled throughout hospitals.  In the United States, breast cancer death rates are significantly higher than any other ...

Researchers designed magnetic nanostructures with an invisibility cloak.  High speed of tiny magnetic bit structures can be achieved by carefully adjusting the strength of the invisible cloak.  For high-performance solid-state data storage and logic applications, researchers are focusing on spin-based devices. One of the promising approaches is to encode bits by small skyrmions or domain ...

A new tool uses the Nitrogen-Vacancy center defect in diamond to simultaneously detect magnetic fields in different directions.  It creates a 3D picture of magnetic fields in real-time.  The technology could be utilized in various fields including condensed-matter physics and biology.  The real-time sensing of a dynamic vector magnetic field is required in numerous magnetometry ...

A new method uses high-performance computing algorithms to improve virtual Fractional Flow Reserve simulations. The algorithm is based on machine learning and deep learning acceleration method called Gaussian Process regression.  It can perfectly simulate what’s happening inside the heart within 1-2 minutes.  Most multi-scale model of cardiac mechanics look promising but when it comes to ...

A new tool based on machine learning algorithms can predict a person’s height by looking at his genetic code.  The tool can even tell about his heel bone density and level of education he might achieve in his career.  Most of the functions of living organisms are controlled by their DNA (including how they develop, ...

New electro-optic laser is 100 times faster than conventional ultrafast laser light.  The system is reliable and produces accurate and stable pulses at 30 GHz.  It can be used in biological/chemical imaging and to implement faster communication networks.  Ultrafast lasers generate a series of light pulses that last up to femtoseconds. They can function as ...

A new method would remove the visual distortions in 3D displays without additional heavier optics.  The system creates a clear, 3D image in space which makes it suitable for AR applications.  We mostly interact with digital content through keyboards and 2D touch panels. However, technologies like Virtual Reality(VR) and Augmented Reality(AR) are nowadays promising more ...
