What if scientists could grow elevators to space? Or make phones that last for weeks without a charge? These things could be possible someday with an amazing material like carbon nanotubes. A MIT scientist discusses the curious way researchers create this super-material. Part of the "Science Out Loud" series.

Josh Landis and Mitch Butler discuss metamaterials, a type of nanotechnology. These materials can theoretically make objects disappear from plain sight. This cloaking technology has a wide range of applications and could forever change the view of the world. Part of the Fast Draw Series.
There’s no shortage of ideas about how to use nanotechnology, but one of the major hurdles is how to manufacture some of the new products on a large scale. With support from the National Science Foundation (NSF), UMass Amherst chemical engineer Jim Watkins and his team are working to make nanotechnology more practical for industrial scale manufacturing. Part of the National Science Foundation Series “Science Nation.”
The Nanosystems Engineering Research Center (NERC) for Advanced Systems of Integrated Sensors and Technologies (ASSIST) at North Carolina State University is developing technology that will alert someone when air pollution is about to take its toll on their heart and lungs. ASSIST Director Veena Misra and her multidisciplinary team are using nanotechnology to develop small, wearable sensors that monitor a person’s immediate environment, as well as the wearer’s vital signs.

At the National Science Foundation-funded Center for Environmental Implications of Nanotechnology (CEINT), headquartered at Duke University, scientists and engineers are researching how nanoscale materials affect living things. One of CEINT's main goals is to develop tools that can help assess possible risks to human health and the environment. A key aspect of this research happens in mesocosms, which are outdoor experiments that simulate the natural environment. These simulated wetlands in Duke Forest serve as a test bed for exploring how nanomaterials move through an ecosystem and impact living things. Part of the “Science Nation” series.
The world’s population is projected to increase by 2-3 billion over the next 40 years. Already, more than three quarters of a billion people lack access to clean drinking water and 85 percent live in the driest areas of the planet. Those statistics are inspiring chemist Ben Hsiao and his team at Stony Brook University. With support from the National Science Foundation (NSF), the team is hard at work designing nanometer-scale water filters that could soon make clean drinking water available and affordable for even the poorest of the poor. Part of the National Science Foundation Series “Science Nation.”
