'Orca ears' inspire researchers to develop ultrasensitive undersea microphone (June 25, 2011) -- Researchers have developed a microphone that can be used at any depth in the ocean, even under crushing pressure, and is sensitive to a wide range of sounds, from a whisper in a library to an explosion of TNT. They modeled their device after the extraordinarily acute hearing of orcas. ... > full story
'Quantum magic' without any 'spooky action at a distance' (June 25, 2011) -- 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. ... > full story
Tracing cancer back to its source using computer dissection (June 25, 2011) -- A new computer-based system can distinguish between apparently similar secondary tumors and allow a cancer specialist to trace the metastases back to the site of the original cancer in the patient's body. ... > full story
New insights into the cohesive forces of crystal structures (June 25, 2011) -- A new study has shown that under certain conditions the interactions between carbon-hydrogen (CH) groups, commonly found in organic compounds, may be much stronger than previously thought. ... > full story
Astronomers reach for the stars to discover new cancer therapy (June 25, 2011) -- 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. ... > full story
Mantis shrimp eye could improve high-definition CDs, DVDs (June 24, 2011) -- 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. ... > full story
High technology, not low taxes, may drive US states' economic growth (June 24, 2011) -- High-tech training may trump tax breaks for creating more jobs and improving a state's economy, according to a new study by economists. ... > full story
Optical circuit enables new approach to quantum technologies (June 24, 2011) -- Scientists have demonstrated a fundamental building block for quantum computing that could soon be employed in a range of quantum technologies. ... > full story
Genes at the flick of a light switch: Human cells fitted with synthetic signaling cascade (June 24, 2011) -- Researchers from Switzerland have fitted human cells with a synthetic signaling cascade that can be used to switch on and regulate genes via blue light. This "gene light switch" makes interesting therapies possible, which could be used to treat type 2 diabetes, for instance. ... > full story
Sun and planets constructed differently than thought, NASA mission suggests (June 24, 2011) -- Researchers analyzing samples returned by NASA's 2004 Genesis mission have discovered that our sun and its inner planets may have formed differently than previously thought. ... > full story
Next-generation gene sequencing brings personal genomics closer, IDs mutation in new syndrome (June 24, 2011) -- Harnessing the new generation of rapid, highly accurate gene-sequencing techniques, a research team has identified the disease-causing mutation in a newly characterized rare genetic disease, by analyzing DNA from just a few individuals. The power and speed of the innovative bioinformatics tool marks a step toward personalized genomics -- discovering causative mutations in individual patients. The previously unknown lethal syndrome has affected infant boys in two unrelated families. ... > full story
Physicist's discovery alters conventional understanding of sight (June 24, 2011) -- Physicists shed new light on how the visual process is initiated. For almost 50 years, scientists have believed that light signals could not be initiated unless special light-receptor molecules in the retinal cells first changed their shape in a process called isomerization. However, researchers have now demonstrated that visual signals can be initiated in the absence of isomerization. ... > full story
