In addition to getting its own Facebook page September 10, Nature‘s Antibodypedia released its seventh version November 29. The publisher said in a statement that the new features include search-refining filters and Nature’s manuscript annotation tool. The free, open-access resource includes a catalogue of more than 500,000 antibodies and the results of around 145,000 experiments. The Facebook page, which had almost 1,400 Likes at press time, includes Nature-posted queries such as, “How much research do you do when choosing antibodies to purchase? Any suggestions for providers to add?” and newsy posts like what the 2012 election could mean for science.

The idea of raising the age of Medicare eligibility as a way to save money is not as simple as it may appear, reported NPR. The problem: it would mean only patients with very costly medical care would be covered. Having healthier, 65-year-olds in the mix somewhat dilutes the financial impact, much like younger — think 20-year-olds — are great for insurers because they pay premiums but use fewer services, providing ballast for the more service-intense (i.e., older) patient population. Taking 65-year-olds out of the Medicare mix would be like pulling the healthy 20-somethings out of the pool, and could drive up Medicare premiums.
