Abstract: Ptychographic imaging confronts inherent challenges in applying deep learning for phase retrieval from diffraction patterns. Conventional neural architectures, both convolutional neural ...

A strong blast of Arctic air will drive temperatures sharply lower from the Midwest to the interior Northeast this weekend, bringing the season’s coldest weather so far for many, forecasters say.

Do you believe in Santa? If not, you might find yourself on a train heading toward the North Pole in order to help you believe, or this might just sound like the plot of "The Polar Express" to you.

New research reveals a link between rising temperatures and changes in polar bear DNA, which may be helping them adapt and survive in increasingly challenging environments. The study by scientists at ...

Cold, Arctic air is severe. Fortunately, year-round, that air is usually kept tightly contained in the North Pole. Arctic wind patterns create a sort of wall around the pole that prevents frigid air ...

The polar vortex has broken, and severe temperatures are set to dominate most of the country in the coming days. Temperatures in the 10s are forecast for much of the Northeast, and subzero ...
