Closed windows Make People Dumb

Researchers have found that moderately high indoor concentrations of carbon dioxide (CO2) can significantly impair people’s decision-making performance. These results have implications for schools and office buildings with high occupant density and windows that do not open. They may also have implications for ALL of us, if climate change causes CO2 levels to continue to build up in the atmosphere–we may end up being dumber just at the time when we need to get SMARTER!

Discovery of a Planet That May Support Life

Astronomers have discovered another potentially habitable planet–that’s 7 times the mass of Earth. Six planets orbit dwarf star HD 40307g, and one of them is believed have the potential to support human life.
The planet seems to be rotating on its own axis, instead of having one face permanently turned toward its sun, meaning it has an Earth-like day and night cycle. This is a major indicator of potential life. Also, it orbits at a distance of 55.8 million miles from its sun, which puts it in its host star’s habitable zone, where liquid water can exist on a planet’s surface.
It’s close by (space travel-wise, anyway)–only 44 light years away. It’s so close that astronomers may be able to spy on it with telescopes.
