<jats:p>This week's Newsmakers are astronaut Sally Ride, the first American woman to travel to outer space, who died this week of pancreatic cancer, and University of Oxford neuroscientist Stephen Emmott, who gave an hourlong "performance" on the subject of population.</jats:p>

<jats:p>Computer researchers are helping viewers take in the world's largest piece of community folk art, the AIDS Memorial Quilt. Artist Heather Dewey-Hagborg has been printing three-dimensional masks, or approximations, of people's faces based on DNA sequenced from their hair. And this week's numbers quantify two grants to treat HIV and malaria and tonnes of global emissions of carbon dioxide in 2011.</jats:p>

<jats:p>The aging scientific facilities in Antarctica are in dire need of repair and upgrades—and paying for that will require cuts to Antarctic research activities in the short term, according to a new report.</jats:p>

<jats:p>Last week, the team that discovered Gliese 581g, the first potentially habitable planet outside the solar system, concluded that their own analysis of their critics' data shows that Gliese 581g does indeed exist.</jats:p>

<jats:p>Last week, a House of Representatives panel passed a 2013 spending bill that would freeze the budget of the National Institutes of Health and trim the Department of Health and Human Services.</jats:p>

<jats:p> Researchers have found a better way to estimate CO <jats:sub>2</jats:sub> emissions: by measuring the proportion of CO <jats:sub>2</jats:sub> in the atmosphere that contains the radioactive isotope carbon-14. </jats:p>
