Ethicists question impact of hospital advertising

Ethicists question the impact of health information that is available online, specifically hospital advertisements, and argue that while the Internet offers patients valuable data and tools — including hospital quality ratings and professional treatment guidelines - that may help them when facing decisions about where to seek care or whether to undergo a medical procedure, reliable and unbiased information may be hard to identify among the growing number of medical care advertisements online.

DNA nanoswitches reveal how life's molecules connect

'Bio-molecular interaction analysis, a cornerstone of biomedical research, is traditionally accomplished using equipment that can cost hundreds of thousands of dollars,' said the senior author of a new study. 'Rather than develop a new instrument, we've created a nanoscale tool made from strands of DNA that can detect and report how molecules behave, enabling biological measurements to be made by almost anyone, using only common and inexpensive laboratory reagents.'

Mobile and interactive media use by young children: The good, the bad and the unknown

Mobile devices are everywhere and children are using them more frequently at young ages. The impact these mobile devices are having on the development and behavior of children is still relatively unknown. Researchers review the many types of interactive media available today and raise important questions regarding their use as educational tools, as well as their potential detrimental role in stunting the development of important tools for self-regulation.
