(Phys.org) —Gaining control of the ability of mature tissues to generate stem cells is the central medical challenge of our day. From taming cancer, to providing compatible cell banks for replacement organs, knowledge of ...
As CO2 levels in the Earth's atmosphere top 400 parts per million, options such as storing the greenhouse gas in porous sandstone rock formations found in abundance on the sea floor are of increasing interest. But how do ...

(Phys.org)—A large multinational team of researchers, led by Markku Kulmala of Finland's University of Helsinki, has for the first time discovered the birth process of a class of aerosols. As they describe in their paper ...
When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn't matter that much. And that's good news for reducing the uncertainty of climate model predictions.
