U.S. lags in life expectancy gains
Among developed countries, Americans spend the most on health care even as they fall behind in extending longevity, a new study finds.

Citation-amnesia paper published
Many biomedical researchers fail to put their findings into context by citing related, previously published work. I termed this citation amnesia, when I wrote about it 18 months ago, based on data presented at a meeting on peer review and publishing. Readers who seek more details than my initial blog provided can now pore over the stats from that research for themselves. The Johns Hopkins University team that I encountered at the Vancouver meeting has now formally published its analysis.

Tallying the caloric cost of an all-nighter
Sleep is energy-saving, and missing even one night sends the body into conservation mode, new measurements show.
