Nanoscience is well on its way to establishing itself as one of the critical technologies of the 21st Century. Just as semiconductors gave rise to computers, smart phones, the Internet, medical devices, and an endless stream of consumer products, nanoscience is enabling the development of new technologies in fields as diverse as electronics, medicine, photonics, energy, and quantum physics. Nanoscale constructions provide this flexibility for two reasons. First, they are small and precise enough to interact with molecules in entirely new ways. Nanomedicines, for example, often encapsulate drugs in molecular packages decorated with segments of molecules that enable them to target specific organs and diseases, and, once there, convince those cells to ingest the medication. Metal-organic frameworks, complex molecules engineered to reduce energy use in chemical reactions and capture carbon emissions from combustion, are another example. Second, and more intriguingly, nanoscale devices are closer in size to electrons and photons, and may interact with them in ways that are fundamentally different from the behavior of larger objects. For example, metamaterials, arrays of nanoscale structures, can bend light around an object to make it appear invisible. Nanoscale electronics can exploit quantum phenomena, like electron spin, energy waves, and quantum states to capture, store, and process information. As these technologies and other emerging applications reach commercialization, they are certain to change nearly every sphere of life.

The Next Life of Silicon

Apr 04, 2014

We live in the Age of Silicon, yet silicon microprocessors have begun to show signs of age, and for all its flexibility, silicon may be part of the problem. Is silicon up for the challenge, or are we entering a new age? We invited five experts to discuss the future of silicon.

2014 Annual Meeting Communicating Science Seminar

Mar 06, 2014

Seminar from the 2014 AAAS Annual Meeting, shares science communication expertise in working with different types of content, across a range of formats, for various audiences. The session was separated into three videos, with each video relating to engagement with one of these audiences:  journalists, social media and public events.
