Heart valve replacement without opening the chest gives new option for non-operable patients Posted: 24 Jun 2011 10:00 AM PDT An innovative approach for implanting a new aortic heart valve without open-heart surgery offers hope for patients with severe aortic stenosis who are at high-risk or not suitable candidates for open heart valve replacement surgery.

More than 300 new species discovered in the Philippines Posted: 24 Jun 2011 10:00 AM PDT This spring, scientists conducted the most comprehensive scientific survey effort ever conducted in the Philippines, documenting both terrestrial and marine life forms from the tops of the highest mountains to the depths of the sea. The scientists discovered more than 300 likely new species, including dozens of new insects and spiders, deep-sea armored corals, bizarre new sea urchins, a shrimp-eating swell shark, and over 50 colorful new sea slugs.

Astronomers reach for the stars to discover new cancer therapy Posted: 24 Jun 2011 08:19 AM PDT Research on celestial bodies may have an impact on the human body. Astronomers are working with medical physicists and radiation oncologists to develop a potential new radiation treatment -- one that is intended to be tougher on tumors, but gentler on healthy tissue.

Mantis shrimp eye could improve high-definition CDs, DVDs Posted: 24 Jun 2011 08:19 AM PDT The eye of the peacock mantis shrimp has led an international team of researchers to develop a two-part waveplate that could improve CD, DVD, blu-ray and holographic technology, creating even higher definition and larger storage density.

'Quantum magic' without any 'spooky action at a distance' Posted: 24 Jun 2011 08:19 AM PDT Quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as "spooky action at a distance". Researchers have used a system which does not allow for entanglement, and still found results which cannot be interpreted classically.

Optical circuit enables new approach to quantum technologies Posted: 24 Jun 2011 08:19 AM PDT Scientists have demonstrated a fundamental building block for quantum computing that could soon be employed in a range of quantum technologies.

Mechanics of speciation: Model examines factors that contribute to emergence of new species Posted: 24 Jun 2011 08:19 AM PDT Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species, according to a new mathematical model that integrates all three factors to reveal the dynamics at play in a process called sympatric speciation.

Hidden lives of Baltimore's Irish immigrants unearthed for first time Posted: 24 Jun 2011 08:19 AM PDT Archaeologists are unearthing a unique picture of early Irish immigrants in the Baltimore area -- of city children taught at home to read and write before widespread public education or child labor laws, and insular rural communities defying assimilation.

New genetic risk factors of lupus found in study of African-American women Posted: 24 Jun 2011 08:19 AM PDT Researchers have found four new genetic variants in the major histocompatibility complex (MHC) that confer a higher risk of systemic lupus erythemathosus ("lupus") in African American women. The study is believed to be the first to comprehensively assess the association between genetic variants in the MHC region and risk of lupus in African American women.

Common drugs linked to cognitive impairment and possibly to increased risk of death, study suggests Posted: 24 Jun 2011 08:19 AM PDT A large, long-term study confirms that medications with anticholinergic activity, which include many drugs frequently taken by older adults, cause cognitive impairment. The research is also the first to identify a possible link between these drugs -- which include over-the-counter and prescription sleep aids and incontinence treatments -- and risk of death.
