Medieval skeletons help reveal genetic causes of bone tumors – Medievalists.net

Leave a Comment / Genetics / By

Two men buried in a medieval cemetery in Ireland suffered from a genetic condition called multiple osteochondromas, which causes benign bone tumors. One of the disease mutations is a new discovery, so this is the first time such insights have been unlocked from ancient genomic data. In 2003, a cemetery was discovered in Ballyhanna, which …

Discovery of life on Titan could reveal clues to early life in the universe

Leave a Comment / Outer space / By

Saturn’s largest moon, Titan, has a surface temperature of 94 degrees Kelvin above absolute zero, about one-third that of Earth. Titan is located 9.5 times further than the Earth-Sun separation, and the surface temperature of solar system objects decreases roughly as the square root of their distance from the Sun. Coincidentally, 94 degrees was the …

Galactic cannibal Andromeda feasts on smaller galaxies, reveal cosmic remnants

Leave a Comment / Science / By

Andromeda, the Milky Way’s neighboring spiral galaxy, may be a cosmic cannibal that grew by swallowing smaller galaxies. Astronomers came to this conclusion by observing a globular cluster of stars called the Dulais Structure, named after the Welsh term meaning “dark stream”, which now dwells in Andromeda but seems to come from outside galaxy. The …
