Evolution on the inside track: How viruses in gut bacteria change over time Posted: 26 Jul 2013 04:15 PM PDT The digestive tract is home to a vast colony of bacteria, as well as the myriad viruses that prey upon them. Because the bacteria species vary from person to person, so does this viral population, the virome. By closely analyzing the virome of one individual over two-and-a-half years, researchers have uncovered new insights on the virome can change and evolve -- and why the virome of one person can vary so greatly from that of another.

Glass scaffolds help heal bone, show promise as weight-bearing implants Posted: 26 Jul 2013 07:33 AM PDT Researchers have developed a type of glass implant that could one day be used to repair injured bones in the arms, legs and other areas of the body that are most subject to the stresses of weight.

Global warming to cut snow water storage 56 percent in Oregon watershed Posted: 26 Jul 2013 06:24 AM PDT A new report projects that by the middle of this century there will be an average 56 percent drop in the amount of water stored in peak snowpack in the McKenzie River watershed of the Oregon Cascade Range -- and that similar impacts may be found on low-elevation maritime snow packs around the world.

Fossil shows fish had sucker on its back Posted: 26 Jul 2013 04:42 AM PDT A 30-million year-old fossil has revealed how remoras -- also called sharksuckers -- evolved the sucker that enables them to stick to other fishes and 'hitch a ride'.

Polymer ribbons for better healing Posted: 26 Jul 2013 04:40 AM PDT Researchers have developed hydrogels for tissue regeneration that can be fine-tuned to fit any body part.

Largest magnetic fields in the universe Posted: 26 Jul 2013 01:34 AM PDT Numerical simulations show for the first time the occurrence of an instability in the interior of neutron stars that can lead to gigantic magnetic fields, possibly triggering one of the most dramatic explosions observed in the Universe.
