A 30,000-year-old vulture feather represents a “two-for-the-price-of one” discovery: the fossil itself, and the first evidence that volcanic ash can preserve such soft tissues in exquisite detail.The feather itself is not a new find; a Roman landowner in 1889 came across evidence of entire bird preserved as a three-dimensional impression. Its details included eye lids and wing feathers. However, new research published in the journal Geology demonstrates that preservation extends to microscop ...read more
Sitting in traffic can expose a driver to intense irritation, as well as a range of sound frequencies. Humming engines typically emit low-frequency sounds, while car horns release high-frequency blasts. Emergency vehicle sirens are high-pitched, and the rumblings from large trucks are lower-pitched.For most people, their ears are able to process these wide-ranging sounds and make sense of them. However, scientists don’t have a full sense of why this happens because they are still working to un ...read more
Gas emissions, earthquakes, and ground deformations. These are all signs that a volcano is about to erupt, and they are also all signs that have appeared at Mount Spurr, an active volcano in southcentral Alaska, around 80 miles west of Anchorage.According to the team at the Alaska Volcano Observatory, “significantly elevated” emissions of volcanic gas have been detected at the volcano — the tallest in the Aleutian Arc — this month, along with elevated earthquake activity and ground defor ...read more
While Earth’s one and only moon enthralls everyone on this planet, it can’t hold a candle to Saturn’s 274 moons, 128 of which were recently discovered and recognized by the International Astronomical Union. With this new surge in its moon count, Saturn prevails with the most moons out of any other planet in the Solar System. Astronomers are now wondering, though, how this abundance of moons emerged in the first place.Regular vs. Irregular MoonsAlthough Saturn boasts an impressive amount of ...read more
On both page and screen, we’re used to seeing dinosaurs and prehistoric birds as vibrant creatures exhibiting unique and diverse patterns in color and texture. But what about the mammals roaming the earth alongside them?In a new study published in Science, an international team of scientists has discovered that early mammals had dark and dull fur, no matter the species. This uniform fur coloring had evolutionary advantages and allowed mammals to avoid becoming prey to their more colorful neigh ...read more
