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.

Calculating the true cost of a ton of mountaintop coal

Posted: 11 Sep 2013 03:48 PM PDT

To meet current US coal demand through surface mining, an area of the Central Appalachians the size of Washington, D.C., would need to be mined every 81 days. A one-year supply of coal would require converting about 310 square miles of the region's mountains into surface mines, according to a new analysis.

Astronomers explain why disk galaxies eventually look alike

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.

Century old chemistry problem solved: Foundational reaction on stubborn chemicals may improve drug synthesis

Posted: 11 Sep 2013 10:17 AM PDT

Chemists have found a way to apply a "foundational reaction" of organic chemistry to a stubborn class of chemicals, in a transformation that has been thought impossible for a century.

Nano-optics: Integrated optical circuits coming soon?

Posted: 11 Sep 2013 09:53 AM PDT

An experimental demonstration of light scattering controlled by silicon nanoparticles augurs well for the development of integrated optical circuits.

New system allows cloud customers to detect program-tampering

Posted: 11 Sep 2013 08:47 AM PDT

A new version of "zero-knowledge proofs" allows cloud customers to verify the proper execution of their software with a single packet of data.

Airbrushing could facilitate large-scale manufacture of carbon nanofibers

Posted: 11 Sep 2013 07:34 AM PDT

Researchers have used airbrushing techniques to grow vertically aligned carbon nanofibers on several different metal substrates, opening the door for incorporating these nanofibers into gene delivery devices, sensors, batteries and other technologies.

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.

Robots take over economy: Sudden rise of global ecology of interacting robots trade at speeds too fast for humans

Posted: 11 Sep 2013 06:31 AM PDT

Recently, the global financial market experienced a series of computer glitches that abruptly brought operations to a halt. One reason for these "flash freezes" may be the sudden emergence of mobs of ultrafast robots, which trade on the global markets and operate at speeds beyond human capability, thus overwhelming the system.
