| Plants in space: A novel method for fixing plant tissue samples maximizes time, resources, and data Posted: 11 Sep 2013 03:48 PM PDT Researchers are working to understand plant growth and development in spaceflight. They have developed a single fixation protocol for use in space that allows plant material to be used for multiple experimental applications. The new protocol boasts low costs and wide application to any situation where recovery of biological resources is limited. |
| Astronomers explain why disk galaxies eventually look alike Posted: 11 Sep 2013 10:17 AM PDT Astronomers have discovered the fundamental process responsible for the smooth, steady fade of older disk galaxies. They say the key is the clumps of interstellar gases and new stars within young galaxy disks. |
| Map of galactic clouds where stars are born takes shape Posted: 11 Sep 2013 06:32 AM PDT Astronomers have completed the first stage of a map of the location of the most massive and mysterious objects in our galaxy -- the giant gas clouds where new stars are born. They identify the clouds -- which can be up to 100 light years across -- from the carbon monoxide they contain. |
