A polar vortex split high in the stratosphere is expected to send frigid Arctic air toward Michigan and the Great Lakes. The event could bring colder-than-normal temperatures and late frosts to the ...

View post: HBO Is Premiering the Final Season of One of Its Biggest Shows Tonight A cold front will bring plunging temperatures and snow to the Northeast this week. Polar vortex disruptions, caused by ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

There is a major weather pattern change underway across the U.S. As we get into next week, the storm track looks really interesting. Major upper-air pattern changes are quite normal. Sometimes we have ...

The bitter cold temperatures that have left a chill over the eastern half of the country aren’t going anywhere, as a major disruption to the polar vortex is coming this month. While the cold is not ...

It’s an understatement to say it’s been a very cold winter. And it’s not close to being over. Reviewing our longer-term weather patterns, we are likely in for more freezing days ahead. You can thank a ...

Waves of frigid air will continue to be released into much of the eastern United States through at least the middle of the month. The ongoing pattern may trend stormier with areas of snow and ice ...

Severe temperatures are expected to dominate most of the country in the coming days, with single-digit temperatures forecast for parts of the Northeast. Overall, temperatures will begin to warm in the ...

On-demand control of stable toroidal vortices lays groundwork for robust wireless data encoding. (Nanowerk News) Researchers have created an optical device that can generate both electric and magnetic ...

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns. These structured light vortices, known as skyrmions, are highly stable and ...

Researchers used a nonlinear metasurface to experimentally demonstrate skyrmions that can be switched between electric and magnetic modes in free-space toroidal terahertz light pulses. WASHINGTON — ...
