Intermediate glucose control may be better than tight in neurocritical care patients
A new study in BioMed Central's open access journal Critical Care suggests that intensive glycemic control does not reduce mortality in neurocritical care patients and could, in fact, lead to more neurological damage.
More pediatric hospitalists using text messaging to communicate
More pediatric hospital physicians are communicating through cell phone text messaging, rather than the traditional pager method, according to research presented Oct.

#537 Science Journalism, Hold the Hype
Everyone's seen a piece of science getting over-exaggerated in the media. Most people would be quick to blame journalists and big media for getting in wrong. In many cases, you'd be right. But there's other sources of hype in science journalism. and one of them can be found in the humble, and little-known press release. We're talking with Chris Chambers about doing science about science journalism, and where the hype creeps in.
