Triggering Cancer Cells To Self-Destruct Could Help Tumors to Shrink

Posted on Categories Discover Magazine

Cancer is the second leading cause of death in the U.S., claiming around 600,000 lives in 2022 alone. A diagnosis can be devastating, as the disease can often resist treatment and spreads uncontrollably.Now, a research team from The Jackson Laboratory (JAX) and UConn Health has identified a potential therapeutic strategy to halt or reverse tumor growth. Their study, published in Nature Communications, reveals how cancer cells disable a built-in "off switch" — and how reactivating it could stop ...read more

Ancient Vulture Feather Preserved in Volcanic Ash Is a Fossil First

Posted on Categories Discover Magazine

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

Physics Can Explain How the Inner Ear Picks Up Faint Sounds

Posted on Categories Discover Magazine

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

Activity at Alaska’s Mount Spurr Suggests That The Volcano Is About To Erupt

Posted on Categories Discover Magazine

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

Saturn’s 128 New Moons May Be Remnants of Past Cosmic Collisions

Posted on Categories Discover Magazine

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
