Nonterrestrial artifacts hard to pin down

A pair of postdoctoral researchers at Penn State suggest that we have not looked in enough places to ensure the absence of extraterrestrial artifacts. They used a probabilistic method to determine if sufficient searching has been done, finding it challenging to rule out their presence.

Breakthrough scientific discoveries no longer dominated by the very young, study finds

A study of Nobel Laureates from 1901 to 2008 found that the majority of breakthroughs in chemistry and physics were made after age 40, with great achievements by age 30 nearly never occurring. The trend toward youthful achievement in early 20th century physics may be attributed to the development of quantum mechanics.
