Feds: Don't expect winter to be polar vortex redux
(AP)—Federal forecasters don't expect a return of frequent cold blasts from the polar vortex this winter. Nor should the weather system that blocked rain from California last winter come back.
Getting to know super-earths: Astronomers conduct atmospheric study of a second super-Earth
"If you have a coin and flip it just once, what does that tell you about the odds of heads versus tails?" asks Heather Knutson, assistant professor of planetary science at Caltech. "It tells you almost nothing. It's the same ...
Past climate change and continental ice melt linked to varying CO2 levels
Scientists at the Universities of Southampton and Cardiff have discovered that a globally warm period in Earth's geological past featured highly variable levels of CO2.
Collapsible wings help birds cope with turbulence
Collapsible wings may be a bird's answer to turbulence according to an Oxford University study in which an eagle carried its own 'black box' flight recorder on its back.

What is the upper limit for massive stars?
Yesterday I mentioned that hypernovae (super-supernovae) are the result of the explosion of a star that's about as massive as a star can be (about 150-200 solar masses). But how exactly do we know that t ...
Study measures impacts of nitrogen deposition on coastal waters
Scientists have a good understanding of how air pollution impacts human health and the terrestrial biosphere, but what impact does air pollution have on oceans? To help answer this question, this past August, ...

New method efficiently estimates surface reflectivity from incoming sunlight bounced back by clouds
Capturing sunlight reflected off the Earth's surface and bounced off a cloud back to the Earth is an effective measure of surface reflectivity—or surface albedo, the measure of how mirror-like the Earth's ...
Cyanide ice in Titan's atmosphere
Gigantic polar clouds of hydrogen cyanide roughly four times the area of the UK are part of the impressive atmospheric diversity of Titan, the largest moon of Saturn, a new study led by Leiden Observatory, ...
