Science News Roundup: Key Discoveries

Artemis II astronauts have shattered spaceflight records, traveling an unprecedented 252,756 miles from Earth—the farthest humans have ever journeyed from our home planet. This historic mission also yielded a compelling candidate for the longest-distance image of humans ever taken, a blurry photo of the crewed Orion capsule captured from 213,000 miles away by an Earth-based telescope.

Polycystic Ovary Syndrome (PCOS) has been officially renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS) to more accurately reflect its complex, multisystem nature beyond just ovarian involvement, as reported by the Endocrine Society. This change, the culmination of a 14-year process, aims to improve diagnosis and treatment by emphasizing the metabolic and hormonal aspects of the condition.
Neanderthals are now considered the world's oldest dentists, with evidence from a 60,000-year-old molar found in Siberia showing intentional dental intervention using stone tools to treat a cavity. This discovery, highlighted by *Live Science*, pushes back the timeline of sophisticated dental practices by tens of thousands of years.
Scientists have discovered a new, "impossible" type of crystal, a clathrate, within trinitite formed during the 1945 Trinity nuclear test, as detailed by *Science Alert*. This unique crystal, never before seen in nature or nuclear explosion products, underscores how extreme conditions can generate unexpected crystalline matter.
A distant image of the Artemis II astronauts circling the Moon, captured by an Earth-based telescope, is a compelling candidate for the longest-distance image of humans ever taken from Earth, according to *Live Science*. The blurry photo, taken from approximately 213,000 miles away, shows the crewed Orion capsule as a handful of pixels.
Beyond the distant image, the Artemis II mission itself set a new record for human spaceflight, with its four astronauts traveling 252,756 miles from Earth, surpassing the previous record held by Apollo 13 in 1970, as reported by NASA. This achievement marks the farthest distance humans have ever traveled from our home planet.
