Polar bears may inhabit a vastly different habitat than bears in Alberta, but the species have at least one thing in common — both are interacting with humans at an increasing rate. Communities in Calgary and Banff have had several run-ins with black and grizzly bears this fall, as have
Humans are born wonderers. We’re always wondering about the next valley over, the next horizon, what we’ll understand next about this vast Universe that we’re all wrapped up in. In 2015, we finally detected our first long-awaited and long-theorized gravitational wave from the distant merger of two stellar mass black holes. But now we want […]
Scientists at City of Hope have identified a cell metabolism process found in men with diabetes and metastatic prostate cancer that could one day lead to improved testing and treatments for Black men with these diseases. The research was highlighted at the American Chemical Society (ACS) Fall 2023, a hybrid meeting held virtually and in […]
The Chinese spy balloon that flew across North America earlier this year exposed important gaps in the United States’ ability to detect airborne threats and propelled the development of new surveillance technology, the senior U.S. commander responsible for patrolling the skies told NBC News in an exclusive interview. Gen. Glen VanHerck, head of the U.S. […]
On May 24, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) began an 18-month campaign to detect the most distant collisions between black holes and neutron stars ever observed. “We’re very excited,” said Michael Landry, head of LIGO Hanford Observatory. Thanks to upgrades, LIGO’s detectors are now so sensitive they can measure gravitational waves — […]
Once every 10,000 years or so, the center of a galaxy lights up as its supermassive black hole rips apart a passing star. This “tidal disruption event” happens in a literal flash, as the central black hole pulls in stellar material and blasts out huge amounts of radiation in the process. Astronomers know of around […]
