Tiny Light-Activated Gold-Covered Nanowires Can Make Neurons Fire

Posted by in categories: genetics, nanotechnology, neuroscience, solar power, sustainability

Researchers at the University of Chicago have developed light-activated nanowires that can stimulate neurons to fire when they are exposed to light. The researchers hope that the nanowires could help in understanding complex brain circuitry, and they may also be useful in treating brain disorders.

Optogenetics, which involves genetically modifying neurons so that they are sensitive to a light stimulus, has attracted a lot of attention as a research tool and potential therapeutic approach. However, some researchers have misgivings about optogenetics, as it involves inserting a gene into cells, potentially opening the door to unforeseen effects and possibly permanently altering treated cells.

In an effort to develop an alternative, a research team at the University of Chicago has devised a new modality that can enable light activation of neurons without the need for genetic modification. Their technique involves nanowires that are so small that if they were laid side-by-side, hundreds of them would fit on the edge of a sheet of paper. Although initially designed for use in solar cells, their small size also makes them well suited to interacting with cells.

Caltech and Grumman partner on Space Based Solar Power Initiative

Posted by in categories: solar power, space travel, sustainability

Space Solar Power Initiative (SSPI) is a multi-year research in the field of Space Solar Power Initiative conducted by Caltech team in collaboration with Northrop Grumman (NG) Aerospace and Mission Systems division.

SSPI approach: • Enabling technologies developed at Caltech • Ultra-light deployable space structures • High efficiency ultra-light photovoltaic (PV) • Phased Array and Power Transmission • Integration of concentrating PV, radiators, MW power conversion and antennas in single cell unit • Localized electronics and control for system robustness, electronic beam steering • Identical spacecraft flying in formation • Target is specific power over 2000 Watts per kilogram. This would cost competitive with ground-based power.

Gen-next smart solar windows could produce electricity

Posted by in categories: solar power, sustainability

Washington: Scientists have discovered a new material for next-generation smart windows that not only darken automatically when the Sun is too bright but also convert solar energy into electricity.

Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) in the US found a form of perovskite that works well as a stable and photoactive semiconductor material that can reversibly switch between transparent and non-transparent state, without degrading its electronic properties.

The scientists made the discovery while investigating the phase transition of the material, an inorganic perovskite.

How a Machine That Can Make Anything Would Change Everything

Posted by in categories: biotech/medical, food, internet, solar power, sustainability

But the dream of the nanofabricator is not yet dead. What is perhaps even more astonishing than the idea of having such a device—something that could create anything you want—is the potential consequences it could have for society. Suddenly, all you need is light and raw materials. Starvation ceases to be a problem. After all, what is food? Carbon, hydrogen, nitrogen, phosphorous, sulphur. Nothing that you won’t find with some dirt, some air, and maybe a little biomass thrown in for efficiency’s sake.

Equally, there’s no need to worry about not having medicine as long as you have the recipe and a nanofabricator. After all, the same elements I listed above could just as easily make insulin, paracetamol, and presumably the superior drugs of the future, too.

What the internet did for information—allowing it to be shared, transmitted, and replicated with ease, instantaneously—the nanofabricator would do for physical objects. Energy will be in plentiful supply from the sun; your Santa Clause machine will be able to create new solar panels and batteries to harness and store this energy whenever it needs to.
