The 4th Strategies for Engineered Negligible Senescence (SENS) conference is open for registration and abstract submission. SENS4 is "to be held at Queens' College, Cambridge, England on September 3rd-7th 2009. The early registration and abstract submission deadlines are both June 15th. All details, including forms for abstract submission and online registration, are at the conference website ... The preliminary program already has 35 confirmed speakers, all of them world leaders in their field. As for previous SENS conferences, the emphasis of this meeting is on "applied gerontology" - the design and implementation of biomedical interventions that may, jointly, constitute a comprehensive panel of rejuvenation therapies, sufficient to restore middle-aged or older laboratory animals (and, in due course, humans) to a youthful degree of physiological robustness. ... In addition, there will be at least a dozen short talks selected from submitted abstracts, as well as poster sessions each evening. Authors of short talks and posters will, like the invited speakers, be invited to submit a paper summarising their presentation for the proceedings volume, which will be published in the high-impact journal Rejuvenation Research early in 2010."
