With a falling dollar and soaring gold prices, President Donald Trump stepped in on Friday to calm world markets. He nominated Kevin Warsh to head the Federal Reserve, America’s central bank. It’s a key appointment, closely watched around the world. For the markets, at least, the move worked. The dollar rebounded, and gold fell as

Reporters packed the room Thursday for a Monitor Breakfast event with Pennsylvania Gov. Josh Shapiro. And there were plenty of national issues to discuss – immigration raids, political violence, rising antisemitism. But when a reporter introduced herself as having “Pittsburgh roots,” Governor Shapiro couldn’t resist going local. “Great, another Yinzer!” he said, using Pittsburgh slang

The recent unrest in Minnesota has reminded me of the words of an anguished mother from nearly a decade ago: “You could be next.”  That was Valerie Castile’s response in 2017 when a Minnesota jury found the police officer, who killed her son Philando during a routine traffic stop, not guilty. In recent weeks, in

Asteroid 2024 YR4 no longer threatens Earth. Instead, updated calculations show about a 4.3 percent chance that the 60-meter-wide rock could strike the Moon on Dec. 22, 2032, at a velocity of about 14 kilometers per second. The impact would release energy equivalent to about 6.5 million tons of TNT and carve out a crater

In this week's science news, we covered a slew of AI developments that include the growing threat of online chatbot swarms, a Zapotec tomb hailed as Mexico's greatest find in a decade, a breakthrough pancreatic cancer therapy in mice, and the growing threat of dam collapses across the United States.

(Image credit: Andrew Williams) Garmin makes many of the best fitness trackers. There are dedicated models for divers, hikers, mariners and even truck drivers. But the number one audience for these watches? Runners. Any Garmin watch available will make a decent run tracker. A great one, even. Some are truly made for the job, though

Live Science Verdict The Enduro 3 combines Garmin’s high-end fitness features with ultra-long battery life, plus solar charging. Its stamina wasn’t quite as good as the company claims during run tracking, but the watch still lasted almost a month. All you miss out on is the gloss and more smartwatch-like extras of some of its

Researchers analyzed blue straggler stars in 48 galactic globular clusters of diverse sizes, ages, densities, distances and metallicities. This image shows the difference between a loose cluster and a dense cluster.

The sun's rotation rate varies by latitude and depth. The colors represent the rotation rate at each location on the sun. Red represents the slowest rotation and blue, the fastest. (Image credit: NASA/Goddard Space Flight Center Scientific Visualization Studio) Many objects in space rotate. Earth completes a spin in roughly 24 hours, while Venus takes

Astronomers have discovered a new exoplanet orbiting the nearby K-dwarf star HD 137010 after detecting a single, shallow transit in the archival data from NASA’s Kepler extended K2 mission. HD 137010b is estimated to be only 6% larger than Earth, with a surface temperature more similar to Mars — potentially below minus 70 degrees Celsius.
