  1. Urine Screening Could Be Non-invasive HPV Test

    Human papillomavirus (HPV) is one of the most common sexually transmitted infections. Up to 80 percent of sexually active women are infected at some point in their lives and infection with specific “high risk” strains of HPV has an established link to cervical cancer. Current screening by cervical cytology (smear test) is invasive and time-consuming. Several studies have suggested that detecting HPV in urine may be a feasible alternative to cervical sampling, but the accuracy of such a test is still uncertain.

    So, a team of researchers based in London and Spain analyzed the results of 14 studies involving 1,443 sexually active women to determine the accuracy of testing for HPV on urine samples compared with cervical samples obtained by a doctor. The quality of the studies was generally high.

  3. Light Source for Chips Can Be TunedChips that use light, rather than electricity, to move data would consume much less power — and energy efficiency is a growing concern as chips’ transistor counts rise. Of the three chief components of optical circuits — light emitters, modulators and detectors — emitters are the toughest to build. One promising light source for optical chips is molybdenum disulfide (MoS2), which has excellent optical properties when deposited as a single, atom-thick layer. Other experimental on-chip light emitters have more-complex three-dimensional geometries and use rarer materials, which would make them more difficult and costly to manufacture.In the next issue of the journal Nano Letters, researchers from MIT’s departments of Physics and of Electrical Engineering and Computer Science will describe a new technique for building MoS2 light emitters tuned to different frequencies, an essential requirement for optoelectronic chips. Since thin films of material can also be patterned onto sheets of plastic, the same work could point toward thin, flexible, bright, color displays.Read more: http://www.laboratoryequipment.com/news/2014/09/light-source-chips-can-be-tuned

  5. Sharks Inspire Hospital Surfaces to Cut InfectionsTransmission of bacterial infections, including MRSA and MSSA could be curbed by coating hospital surfaces with microscopic bumps that mimic the scaly surface of shark skin, according to research published in BioMed Central’s open access journal Antimicrobial Resistance and Infection Control.The study modeled how well different materials prevented the spread of human disease bacteria through touching, sneezes or spillages. The micro-pattern, named Sharklet, is an arrangement of ridges formulated to resemble shark skin. The study showed that Sharklet harbored 94 percent less MRSA bacteria than a smooth surface, and fared better than copper, a leading antimicrobial material. The bacteria were less able to attach to Sharklet’s imperceptibly textured surface, suggesting it could reduce the spread of superbugs in hospital settings.Read more: http://www.laboratoryequipment.com/news/2014/09/sharks-inspire-hospital-surfaces-cut-infections

The findings seem to corroborate Chopin’s 1849 death certificate, which said the Polish-born musician died at the age of 39 in Paris from TB.He rests in Paris, but in keeping with a Romanticism-era practice his heart was brought to Warsaw, where he grew up, and is kept as a national relic inside a pillar at The Holy Cross Church.

  11. Nanoscience Tastes WineOne sip of a perfectly poured glass of wine leads to an explosion of flavors in your mouth. Researchers at Aarhus Univ. have now developed a nanosensor that can mimic what happens in your mouth when you drink wine. The sensor measures how you experience the sensation of dryness in the beverage.When wine growers turn their grapes into wine, they need to control a number of processes to bring out the desired flavor in the product that ends up in the wine bottle. An important part of the taste is known in wine terminology as astringency, and it is characteristic of the dry sensation you get in your mouth when you drink red wine in particular. It is the tannins in the wine that bring out the sensation that – otherwise beyond compare – can be likened to biting into an unripe banana. It is mixed with lots of tastes in the wine and feels both soft and dry.Read more: http://www.laboratoryequipment.com/news/2014/09/nanoscience-tastes-wine
