Is our universe just one of many? The idea may sound a bit bizarre, but it could be a reality, scientists say.
When meeting strangers in the wild, dolphins whistle signature tunes that may be the animal equivalent of “Hello, my name is…” stickers. These signature whistles have been observed in captive dolphins for decades, but new research is the first to reveal how these sea mammals use the sounds when one pod meets another in the…
The early universe was a vastly different place from the one we see today. No stars burned in faraway galaxies — there weren’t any galaxies. Instead, photons were trapped in a dance with the hot plasma of protons and electrons that suffused the universe. Sound waves rang out across this primordial soup, sloshing gas and…
A new university-backed project aims to investigate cryptic species such as the yeti whose existence is unproven, through genetic testing. Researchers from Oxford University and the Lausanne Museum of Zoology are asking anyone with a collection of cryptozoological material to submit descriptions of it. The researchers will then ask for hair and other samples for…
The world’s air has reached what scientists call a troubling new milestone for carbon dioxide, the main global warming pollutant. Monitoring stations across the Arctic this spring are measuring more than 400 parts per million of the heat-trapping gas in the atmosphere. The number isn’t quite a surprise, because it’s been rising at an accelerating…
Mars wasn’t always the Red Planet. Eons ago, it is possible that Mars was as lush as Earth is today. So, what happened? NASA is on the case with this enlightening video of how Mars may have lost its atmosphere. The idea behind the atmospheric “sputtering” Mars may have experienced is fairly simple to understand….
A team of American, Canadian and Chilean astronomers have stumbled onto a remarkably faint cluster of stars orbiting the Milky Way that puts out as much light as only 120 modest Sun-like stars. The tiny cluster, called Munoz 1, was discovered near a dwarf galaxy in a survey of satellites around the Milky Way using…
