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.

Newly recognized heart cardiomyopathy is not always benign Posted: 09 Mar 2013 12:50 PM PST Even though a newly recognized cardiomyopathy, which mainly impacts women, is typically treatable, Tako-tsubo cardiomyopathy can also be deadly when compounded by other co-morbidities, such as heart failure, according to a new study.

Bathing abdomen in chemotherapy gives ovarian cancer patients better chance of survival Posted: 09 Mar 2013 12:49 PM PST A recent study suggests that patients with advanced ovarian cancer who undergo intensive treatment with chemotherapy that bathes the abdomen are significantly more likely to live longer than those who receive standard intravenous (IV) chemotherapy.

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.

Recommendations for use of electronic health records in pediatrics Posted: 08 Mar 2013 03:38 PM PST In order to speed the development and adoption of electronic health records for pediatrics, a group of experts from industry, academia and government has focused its attention on three key audiences -- records-system vendors and developers, small-group pediatric medical practices and children's hospitals.

New NIST time code to boost reception for radio-controlled clocks Posted: 08 Mar 2013 03:38 PM PST NIST is changing the way it broadcasts time signals that synchronize radio-controlled "atomic" clocks and watches to official US time in ways that will enable new radio-controlled timepieces to be significantly more robust and reliable. This new time broadcast protocol will not only improve the performance of new radio-controlled clocks and watches, but will encourage the development of new timekeeping products that were not practical with the old broadcast system because of local interference or other limitations.

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.

Appetite suppression pills: Good or bad? Posted: 08 Mar 2013 03:37 PM PST There are endless opportunities to spend a small fortune on a box of pills promising to ease hunger and help lose weight – but they may not be as safe as natural ways to reduce hunger.

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.
