Conduction is the direct flow of heat from your warm body into your colder surroundings. In winter, all that heat escaping ...

NASA is backing a new generation of nuclear rockets that could compress the months-long journey to Mars into a sprint ...

Abstract: A novel slow wave structure (SWS), flatted grating folded waveguide (FGFW), has been proposed for terahertz (THz) traveling wave tubes (TWTs). Compared to a conventional folded waveguide (FW ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

A rare SWOT satellite pass captured a Pacific-wide tsunami in high resolution, revealing complex wave patterns that challenge ...

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more ...

Abstract: To suppress the backward wave oscillations in traveling wave tube (TWT) amplifiers, which are caused by the high gain of higher-order modes, mode selective folded waveguide (MSFW) is ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

From frozen bonfires to quantum physics, why light still matters to our hopes, our science and our long Alaska winters.

It’s so new, it’s generally deemed pre-commercial. Revenues are above zero, but barley so. And rather than being normal sales ...

Helium leaks are hard to detect, since it is odorless, colorless, tasteless, and does not react with other chemical ...

Scientists have discovered a way to efficiently transfer electrical current through specific materials at room temperature, a ...
