Early cow’s milk consumption may cut breast-cancer risk
Research studies paint a muddy picture of milk’s malignant threat. Some have linked consumption of cow’s milk with a heightened breast-cancer risk. Others have suggested milk drinking might be protective. A new animal study suggests those data may not be quite as contradictory as they at first seemed.

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.
