| 'Filament' Of Dark Matter Supports 'Bubbly' Universe Theory Posted: 21 Oct 2008 04:00 AM CDT Despite thousands of years of research, astronomers know next to nothing about how the universe is structured. One strong and accepted theory is that large galaxies are clustered together on structures similar to giant soap bubbles, with tinier galaxies sprinkled on the surface of this "soapy" layer. Astronomers have uncovered what they believe are visible traces of a "filament" of dark matter -- an entity on which galaxies meet, cluster and form. A filament can originate at the junction of two "soap bubbles," where the thin membrane is thicker.  |

| Engineers Build First-ever Multi-input 'Plug-and-play' Synthetic RNA Device Posted: 20 Oct 2008 07:00 PM CDT Engineers have created a "plug-and-play" synthetic RNA device -- a sort of eminently customizable biological computer -- that is capable of taking in and responding to more than one biological or environmental signal at a time. Such devices could have a multitude of potential medical applications, including being used as sensors to sniff out tumor cells or determine when to turn modified genes on or off during cancer therapy.  |
| 'Junk' DNA May Have Important Role In Gene Regulation Posted: 20 Oct 2008 07:00 PM CDT For about 15 years, scientists have known that certain "junk" DNA -- repetitive DNA segments previously thought to have no function -- could evolve into exons, which are the building blocks for protein-coding genes in higher organisms like animals and plants. Now, there is evidence that a significant number of exons created from junk DNA seem to play a role in gene regulation. The findings increase understanding of how humans differ from other animals.  |

Now researchers have demonstrated the ability to rapidly write nanoscale protein arrays using a tool they call the nanofountain probe. The probe works much like a fountain pen, only on a much smaller scale, and the "ink" is the protein solution.  |
