Flashes like Cherenkov radiation in space may reveal negative-energy ghosts, hinting at gaps in gravity theories.

A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a ...

In September, the Ontario government announced $18-million in funding to allow McMaster to operate the nuclear reactor around ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

Abstract: This paper presents an X-band high-efficiency dual-mode relativistic Cherenkov oscillator (DM-RCO) operating at low guiding magnetic field. The device comprises a TM01-TM02 mode converter, a ...

LAS VEGAS (KLAS) — Officials are alerting the public to low-flying helicopters expected over the Las Vegas Strip and surrounding areas in the days leading up to New Year’s Eve. The National Nuclear ...

Abstract: A novel subterahertz relativistic coaxial Cherenkov oscillator with an external quality factor regulation mechanism is proposed. This device achieves high output efficiency and power ...

A massive fog bank that has been blanketing much of California’s Central Valley with low-lying clouds since Thanksgiving time has prompted fears online of a mysterious and harmful “radiation fog,” but ...

The IAEA has released a new safety guide to help countries design and run radiation monitoring programmes to ensure people and environment are protected from harmful effects of ionizing radiation.

SACRAMENTO, CALIFORNIA: In late 2025, widespread claims circulated online about a massive blanket of radiation fog covering California’s Central Valley. These claims suggested the fog was mysterious ...
