Scientists at the University of Waterloo are working on a new cancer treatment that uses specially engineered bacteria to consume tumors from the inside. The strategy relies on microbes that naturally thrive in oxygen-free environments, which makes the interior of many solid tumors an ideal target. “Bacteria spores enter the tumor, finding an environment where

In 1953, Russian scientists peeling Scotch tape in a vacuum reported detecting electrons with sufficient energy to emit X-rays. Other scientists were skeptical, but this phenomenon was finally confirmed in 2008, when UCLA physicists produced X-rays while unwinding a roll of Scotch tape in a vacuum chamber. The goal was to harness triboluminescence for X-ray
Just over a year ago, the upper stage of a SpaceX Falcon 9 rocket plummeted back to the ground after delivering 23 Starlink satellites to low-Earth orbit. It was a routine mission, one out of hundreds of rocket launches that have delivered just shy of 10,000 broadband-beaming satellites total into space — and it belched
The big, bulky Nikon D5 powerhouse DSLR from 2016 will be Artemis II’s camera of choice. The four Artemis II astronauts set to make history by traveling further away from Earth than any human in history will be taking 10-year-old DSLR cameras with them — rather than modern mirrorless. Two Nikon D5s will be onboard
The first lunar eclipse of 2026 will transform the moon into a coppery red “blood moon” in the early hours of March 3 for skywatchers in North America. The long-lasting and impressive blood moon on March 3 will be visible to billions within the path of the eclipse, but exactly what you’ll see depends on
A quiet shift in the numbers behind the universe’s growth is pushing scientists toward a bold possibility. Two of the cosmos’ most elusive players, dark matter and neutrinos, may not be strangers after all. New research from the University of Sheffield reports signs they could be interacting, a finding that challenges a core assumption in
Efforts to get NASA’s historic moon mission off the ground have stalled once again, as engineers navigate a new issue with the rocket set to propel four astronauts on an unprecedented path. The agency announced Saturday that it had detected a problem with flow of helium, a gas that’s used to pressurize fuel tanks and
