Bussard (credit: NASA) In Poul Anderson’s 1970 novel Tau Zero, a starship crew seeks to travel to the star Beta Virginis in hopes of colonizing a new planet. The ship’s mode of propulsion was a so-called “Bussard ramjet,” an […]
Halle Berry and Patrick Wilson co-star in director Roland Emmerich’s latest film, Moonfall. Hello, police? I’d like to report a murder—the murder of credible science on the altar of entertainment, as evidenced in the latest trailer for Moonfall. It’s the latest epic disaster blockbuster from director Roland Emmerich, in which the Earth’s existence is threatened by […]

They emit low levels of ionizing radiation that can cause adverse health effects over time. (credit: Rijksinstituut voor Volksgezondheid en Milieu) Worried that 5G cell phone towers […]
Physicists from Argentina and Spain have studied the pedestrian dynamics at the annual running of the particular bulls in Pamplona. In his first and arguably most famous novel, The Sun Also Rises , Ernest Hemingway wrote tersely but lovingly about the annual running of the bulls in Pamplona, Spain, during the seven-day Festival of San […]

(credit: Google) Recently, when researchers were testing error correction on Google’s quantum processor, they noted an odd phenomenon where the whole error-correction scheme would sporadically fail badly. They chalked this up to background radiation, a combination of cosmic rays and the occasional decay of a naturally occurring radioactive isotope. It […]
