| How the daffodil got its trumpet Posted: 09 Mar 2013 01:02 PM PST The daffodil is one of the few plants with a 'corona', a crown-like structure also referred to as the 'trumpet'. New research suggests that the corona is not an extension of the petals as previously thought, but is a distinct organ sharing more genetic identity with stamens, the pollen-producing reproductive organs.  |
| Researchers develop AFM-IR for nanometer scale chemical identification Posted: 08 Mar 2013 03:38 PM PST Researchers report that they have measured the chemical properties of polymer nanostructures as small as 15 nm, using a novel technique called atomic force microscope infrared spectroscopy.  |
| More rapid test for Group B strep successful Posted: 08 Mar 2013 03:38 PM PST A more rapid laboratory test for pregnant women to detect potentially deadly Group B strep (GBS) has been successful at identifying GBS colonization in six and a half hours, according to new results.  |
| Why a hereditary anemia is caused by genetic mutation in mechanically sensitive ion channel Posted: 08 Mar 2013 03:38 PM PST A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a new article.  |
| Quantum refrigerator offers extreme cooling and convenience Posted: 08 Mar 2013 03:38 PM PST Researchers have demonstrated a solid-state refrigerator that uses quantum physics in micro- and nanostructures to cool a much larger object to extremely low temperatures. What's more, the prototype refrigerator, which measures a few inches in outer dimensions, enables researchers to place any suitable object in the cooling zone and later remove and replace it, similar to an all-purpose kitchen refrigerator.  |
| Biological tooth replacement is a step closer Posted: 08 Mar 2013 03:38 PM PST Scientists have developed a new method of replacing missing teeth with a bioengineered material generated from a person's own gum cells. Current implant-based methods of whole tooth replacement fail to reproduce a natural root structure and, as a consequence of the friction from eating and other jaw movement, loss of jaw bone can occur around the implant.  |
| Scientists identify buphenyl as a possible drug for Alzheimer's disease Posted: 08 Mar 2013 03:37 PM PST Studies in mice with Alzheimer's disease (AD) have shown that sodium phenylbutyrate, known as Buphenyl, successfully increases factors for neuronal growth and protects learning and memory, according to neurological researchers.  |
