Fossils from Queensland suggest a newly recognized marsupial order may have survived in Australia for around 35 million years, rewriting part of the story of how the continent's unique mammals evolved. The discovery challenges the idea that Australia's marsupials all came from a single straightforward ancestral lineage. from Latest Science News -- ScienceDaily https://ift.tt/uWH9Jdc

The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow. from Latest Science News -- ScienceDaily https://ift.tt/DKHVlGo

A low-cost antidepressant may offer new hope for people struggling with long COVID fatigue. In a randomized clinical trial involving 399 adults, fluvoxamine significantly reduced fatigue and improved quality of life compared with a placebo, making it one of the first medications to show meaningful benefits for this disabling condition. from Latest Science News -- ScienceDaily https://ift.tt/jFMHanZ

It's not known whether "Ulysses 31" was on Christopher Nolan's radar in his teenage years, but it's intriguing to think it could have influenced the director's decision to take on Homer's "The Odyssey". This animated space opera, a French/Japanese co-production, delivered a crash course in Greek mythology to a generation of kids who grew up in the '80s. And, although it looks more like "Star Wars" than Homer's original tale, it had a decent stab at transferring the Classics to the 31st century (the clue really was in the title), years before the Coen brothers took "The Odyssey" to the Deep South in "O Brother, Where Art Thou?" The cartoon's core premise would be familiar to any Greek scholar, even though purists would surely bristle at the hero going under his Roman pseudonym, Ulysses, rather than the original Gre...

If you still picture Mars as a monotonous red desert, it may be time for an update. The European Space Agency's Mars Express orbiter has been capturing some of the Red Planet's most surreal landscapes, and its latest images reveal a sprawling field that looks like molten metal frozen across the floor of an ancient Mars crater. The shimmering "waves" aren't metal at all, however. They are dark sand dunes dusted with seasonal frost, much of it carbon dioxide, or "dry ice," that settles on the surface during Martian winters, giving the dunes their uncanny chrome-like sheen, according to ESA . The rest is a trick of light and contrast. Because the dark sand absorbs light and the white frost reflects it, the interplay transforms the landscape into something that looks more like a scene from a sci-fi movie than a windswept Martian plain. A bird's-eye view of wind-b...

People keep asking me about the total solar eclipse on August 12 . That's understandable. For anyone in the Northern Hemisphere, it is shaping up to be a joyous day of astronomy. Totality will cross eastern Greenland, western Iceland and northern Spain, but much of Europe will see a very deep partial eclipse, and even parts of North America will see a small bite taken from the sun. Then, just hours later, the Perseid meteor shower will peak beneath perfectly moonless skies. What a double-act! The problem with promoting days and nights like that is that they make us think skywatching is only worth doing at very specific times. Everything becomes about moments, peaks and countdowns. That rings true for an eclipse, of course, but for the Perseids, it's less so. The Perseid meteor shower actually begins right now. It's active from July 17 through August 24. Yes, it reaches a strong maxim...
