However, despite North America being one of the most light-polluted places on the planet, there is a definite east-west divide. In fact, go explore the Colorado Plateau — a…

Black hole jets have recently been found to emit X-rays, and it is still unknown how they accelerate particles to this high-energy state. One of the most popular models on how jets produce X-rays predicts that the jets’ X-ray emissions will remain constant over very long time scales (millions of years). Although, a new study seems…
Credit: Pixabay/CC0 Public Domain A new study has shown that humans may have evolved a spring-like arch to help us walk on two feet. Researchers studying the evolution of bipedal walking have long assumed that the raised arch of the foot helps us walk by acting as a lever which propels the body forward. But…
News password sharing and rewind policies. @xguntherc May 29, 2023, 3:00 pm EDT | 1 min read Justin Duino / Review Geek The controversial Netflix password-sharing crackdown went into full effect this week, with the company sending out emails to those in the United States. As expected, rivals old and new are poking fun at…
These days, the term “Y2K” is mostly associated with a recurring fashion trend. But a couple of decades ago, it was an ominous abbreviation that emerged in the media — and in the worst nightmares of those who experienced it — for a completely different reason.Y2K was shorthand for a potential doomsday scenario that envisioned…
At some point, out-of-office emails lost their meaning. All too often, when someone receives an automated response, they may read and understand the first part—that the person they’re trying to reach isn’t at work—but choose to ignore the second, and arguably more important part, about when they can expect to hear back from them.Or, in…
Termites are often thought to be structural pests, but two researchers have taken a slightly contrarian viewpoint. As detailed in a new paper recently published in Frontiers in Materials, David Andréen of Lund University and Rupert Soar of Nottingham Trent University studied termites’ tens of millions of years of architectural experience exhibited within their massive…
Caltech-led studies propose new, stringent tests for Einstein’s general theory of relativity, seeking signs of quantum gravity in the ripples of spacetime generated by black hole collisions. One study presents an equation for black hole behavior within quantum gravity theories, building on previous work, while the second suggests a method for applying this equation to…
An illustration of NASA’s Cassini orbiter soaring through a giant vapor jet over the moon Enceladus (Image credit: NASA/JPL-Caltech)Scientists caught Saturn’s icy moon Enceladus spraying a “huge plume” of watery vapor far into space — and that plume likely contains many of the chemical ingredients for life. Scientists detailed the eruption — glimpsed by the James…
