Do common painkillers cause kidney failure in children? Posted: 25 Jan 2013 07:41 AM PST Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, are commonly used to treat pain and reduce fever in children. However, the use of NSAIDs has been shown to cause acute kidney injury (AKI) in some children. A new study reports the findings on the number of children diagnosed with AKI caused by NSAIDs in one hospital over an 11.5 year span.

No link found between facial shape and aggression Posted: 25 Jan 2013 07:41 AM PST There is not significant evidence to support the association between facial shape and aggression in men, according to a new study.

At least one in five were infected in flu pandemic, international study suggests Posted: 25 Jan 2013 07:40 AM PST At least one in five people in countries for which data are available were infected with influenza during the first year of the 2009 H1N1 pandemic, according to a new study.

Quantum communication: Each photon counts Posted: 25 Jan 2013 07:40 AM PST Ultrafast, efficient, and reliable single-photon detectors are among the most sought-after components in photonics and quantum communication, which have not yet reached maturity for practical application. Physicist have now, however, achieved a decisive breakthrough by integrating single-photon detectors with nanophotonic chips. The detector combines near-unity detection efficiency with high timing resolution and has a very low error rate.
