'Ghost Light' of Long-Dead Stars Haunt NASA's Hubble Telescope

NASA is adding a cosmic twist to Halloween with an unexpected find by the Hubble Space Telescope: eerie "ghost light" from the remains of a multi-galaxy massacre. As many as six galaxies roughly the size of our own Milky Way met their grisly deaths at the hands of gravity. The celestial bloodbath occurred over a period of 6 billion years in a group of galaxies 4 billion light-years away. Stars from those galaxies, now ripped from their cosmic homes, were seen emitting a "faint, ghostly glow" by the Hubble Space Telescope.

Planetary Atmospheres a Key to Assessing Possibilities for Life

Understanding how permanent an atmosphere is, where it came from, and most importantly what it is made of are key to understanding if a planet outside our solar system is habitable for life. Our instruments aren't yet sophisticated enough to look at atmospheres surrounding Earth-sized planets, but astronomers are starting to gather data on larger worlds to do comparative studies.

Response to Disgusting Images Reveals Political Ideology

Recent research supports the theory that political ideology - whether someone is a liberal or a conservative - can be transmitted through generations. A new study found that conservatives tend to have more magnified responses to disgusting images, but scientists don't know exactly why.

Ebola's Ancient Roots Dig Deep: Disease Goes Back More Than 20 Million Years

Filoviruses, the group of microorganism that include Ebola and the deadly Marburg virus, can be traced back to the Miocene Epoch. This was a period on Earth during which grasslands and kelp gardens first became prominent on the land and sea. Great apes also first evolved during this time, leading to the wide range of primates in the world today. During the period, Ebola and Marburg evolved into separate families of organisms, becoming genetically distinct from each other.

The Red Effect, in People and Monkeys

University of Rochester researchers wondered if the red effect - people finding members of the opposite sex more attractive when they are in close proximity to the color red - reflects cultural influences or if there is a more ancient biological basis to it. In many human cultures, the color red is linked to sex and romance. But if the effect is found in other primates, it could reflect a biologically innate sensory bias.
