Controlling the brain with light earns a physiology Nobel (9 minute read)
Karl Deisseroth, Peter Hegemann, and Georg Nagel have won the Nobel Prize in Physiology or Medicine for their contributions to the field of optogenetics. Optogenetics involves using light to alter the behavior of nerve cells marked by the activity of individual genes. It allows researchers to activate or shut down neurons in an otherwise intact brain. The technique has revolutionized scientists' ability to understand what different populations of nerve cells are doing.

A New Crop of Solar Panels Is the US' Best Hope of Catching China (10 minute read)
Tandem solar is a new technology that adds second and third layers of material on solar panels to convert more of the Sun's radiance into electricity. Several companies plan to start selling panels commercially soon. The panels can generate 25% more energy than current available devices. Successful adoption of the technology will allow the world to meet the rapidly rising demand for electricity with less land and roof area.

It is a form of integration testing, except the software on top is thrown away when the test is complete. Instead of building the core while trying to anticipate what might be needed at the other layers, you just simulate the other layers by building them.

There is an enormous collection of tools that know how to work with plain text, and plain text gives users more choice. Text ages surprisingly well, and it is easy to own. It is portable, inspectable, searchable, scriptable, easy to back up, and remarkably resistant to obsolescence.

The field of mathematics is changing, but mathematics is still as important today as it ever was. Mathematics remains a core capacity for human reasoning and deliberation. Future historians will likely see this time as the start of a new era for mathematics. We are at a new frontier where communal norms, values, and expectations are beginning to break down, and the community needs to figure out what should replace them.
