<jats:p> <jats:italic>Science</jats:italic> Insider this week reported on the release (or so rumor has it) of the much-ballyhooed report on the future of the U.S. human space program, the most comprehensive report yet on geoengineering, the shuddering and unexpected halt of India's moon mission, and other stories. </jats:p>

<jats:p>A new analysis published this week suggests that Paul Kammerer's long-discredited experiments may have been the first demonstrations of a recently recognized phenomenon: epigenetics.</jats:p>

<jats:p> A large team of researchers <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://www.sciencemag.org/cgi/content/abstract/1178746">reports</jats:ext-link> online in <jats:italic>Science</jats:italic> this week that it has identified the most powerful, broad-acting antibodies yet against multiple strains of HIV. </jats:p>

<jats:p> How did cooperation evolve when cheaters—those who benefit without making sacrifices—can threaten its stability? In the ninth essay in <jats:italic>Science</jats:italic> 's series in honor of the Year of Darwin, Elizabeth Pennisi discusses the genetic nuts and bolts of cooperation in systems from microbes to humans. </jats:p>

<jats:p>At the fall meeting of the American Chemical Society, researchers reported that a protein that binds sugar groups on the outermost proteins of HIV, gumming up the virus's machinery for entering cells, does nearly as well against the SARS and Ebola viruses, showing promise as a broad-spectrum antiviral.</jats:p>

<jats:p>At the American Chemical Society fall meeting, a team reported incorporating a mimic of the natural catalyst of photosynthesis into a solar cell to create what amounts to artificial photosynthesis: a device that turns sunlight into fuel.</jats:p>

<jats:p> At the American Chemical Society fall meeting, bioengineers reported equipping photosynthetic algae with the metabolic machinery needed to make isobutanol, a potential alcohol biofuel, and tweaking a reluctant microbe to make large quantities of <jats:italic>n</jats:italic> -butanol, another commercially important chemical. </jats:p>
