Advances in Materials Science Move Energy Innovation
While advances in energy efficiency, electric cars and renewable energy make the news, the big story is how advances in materials science make it all possible. New classes of materials, plus innovations in manufacture and use, have already helped cars and planes use less fuel; produced batteries that are smaller, lighter, and run longer; and…

Homeostatic Sleep Pressure Is the Primary Factor for Activation of Cortical nNOS/NK1 Neurons
Cortical interneurons, immunoreactive for neuronal nitric oxide synthase (nNOS) and the receptor NK1, express the functional activity marker Fos selectively during sleep. NREM sleep ‘pressure’ is hypothesized to accumulate…
