| A solution to sinusitis from the sea Posted: 18 Feb 2013 02:33 PM PST Scientists and surgeons are developing a new nasal spray from a marine microbe originally being investigated to clear the hulls of ships in order to help clear chronic sinusitis.  |
| Meerkats use subordinate animals as guinea pigs when approaching novel threats Posted: 18 Feb 2013 02:32 PM PST In their environment, wild animals are exposed to countless threats, be they predators, diseases or natural obstacles to get over, such as gorges or rivers. In recent times, numerous human-made threats have been added to the naturally-existing ones, such as dangerous roads to cross. Scientists have worked to understand how animals cope with novel human-made threats by studying groups of wild meerkats, a species of socially-living mongooses.  |
| Stem cell-based bioartificial tissues and organs Posted: 18 Feb 2013 07:30 AM PST Surgeons have successfully transplanting bioengineered stem cell-based trachea, composed of both artificial and biological material. Now they plan to use the technique to recreate more complex tissues, such as the esophagus and diaphragm or organs such as the heart and lungs. Researchers have also made an experimental attempt to regenerate brain tissue in mice and rats.  |
| Posted: 17 Feb 2013 10:42 AM PST Scientists have developed a new set of building blocks based on nanoparticles and DNA. Using these tools, scientists will be able to build -- from the bottom up, just as nature does -- new and useful structures. The research team has already built more than 200 different crystal structures with 17 different particle arrangements. Some of the lattice types can be found in nature, but many are new structures that have no naturally occurring mineral counterpart.  |
| In the blink of an eye: X-ray imaging on the attosecond timescale Posted: 17 Feb 2013 10:42 AM PST Scientists have been using powerful laboratory-scale lasers to test whether multidimensional nonlinear x-ray spectroscopy on the attosecond timescale is practical for the light sources of the future -- and just what combination of beam characteristics is needed to define them.  |
| 'The Scars of Human Evolution': Physical fallout from two-footed walking Posted: 17 Feb 2013 05:43 AM PST From sore feet to backaches, blame it on human evolution.  |
| Is there a Neanderthal in the house? Posted: 17 Feb 2013 05:29 AM PST As we humans evolved over the millennia to walk on two legs, grow larger brains and shorter jaws, bear big babies and live longer, we've also experienced some negative consequences. But keeping our evolutionary history in mind can help us better deal with issues from obesity to difficult childbirth in a much more productive way, according to an anthropologist.  |
| 'Acoustic-assisted' magnetic information storage invented Posted: 14 Feb 2013 11:18 AM PST Electrical engineers have discovered a way to use high-frequency sound waves to enhance the magnetic storage of data, offering a new approach to improve the data storage capabilities of a multitude of electronic devices around the world.  |
| Fish become bolder and more gluttonous from mood-altering drug residue in water Posted: 14 Feb 2013 11:17 AM PST Anxiety-moderating drugs that reach waterways via wastewater create fearless and asocial fish that eat more quickly than normal. These behavioral changes can have serious ecological consequences.  |
