January 23, 2013 After researchers created versions of the bird flu virus that could spread more easily, critics began to worry that the work could spawn a pandemic if a virus escaped from the lab. After halting their work for more than a year, scientists now say the benefits outweigh the risks, and they are set to restart their experiments.
January 23, 2013 An NIH working group recommends that most of the agency's 360 research chimpanzees be sent to a sanctuary — a non-laboratory setting where chimps can live more natural lives. But even if the NIH accepts the recommendations, putting them into effect won't be easy.
December 31, 2012 When scientists figured out how to make the deadly H5N1 virus more contagious, a debate ignited about whether to publish the research and do more experiments. Over the past year, scientists published the contentious work, but they still can't agree on the field's future.
December 19, 2012 Scientists recently sparked controversy when they made dangerous new forms of bird flu. The National Institutes of Health is about to put in place a new system for reviewing this kind of work in the future.
December 18, 2012 On Tuesday, the National Institutes of Health in Maryland is holding a second day of talks about whether and how to continue funding some controversial scientific experiments. Back in January, virologists agreed to temporarily stop research that was creating new forms of bird flu, because critics argued that the work was too dangerous.
December 7, 2012 It's been 40 years since NASA launched Apollo 17, its final human mission to the moon. The commander of that mission says he'd love to give up his claim to fame as "the last man on the moon" but concedes that it probably won't happen in his lifetime. And future trips might be run by companies in the private sector.
November 23, 2012 Some scientific research can't be completed in days or months — projects can take years, or even decades or centuries. This poses a challenge for scientists who must make plans for experiments that often outlive the experimenter.
November 22, 2012 Candied yams with a touch of marshmallow cream are what the astronauts on the International Space Station are looking forward to eating for their Thanksgiving feast today. That and a little irradiated smoked turkey, courtesy of NASA.
November 21, 2012 Ultrasound often catches fetuses opening their mouths, but whether they're really yawning or not has been up for debate. Now, with some fancy ultrasound techniques, scientists have show that babies do indeed yawn in the womb.
November 2, 2012 Scientists say an Asian elephant at a South Korean zoo can imitate human speech, uttering five Korean words that are readily understood. "This is not the kind of sound that Asian elephants normally make, and it's a dead-on match of the speech of his trainers," a researcher says.
October 17, 2012 Researchers have found a planet orbiting a neighboring star that's similar to our sun. Alpha Centauri B is a staple of science fiction, because the star is so close to our own solar system. Now scientists say they have evidence that the star is orbited by at least one planet and where there's one, there's probably more.
