The $408 million TDRS-M was built and launched with the sole purpose to extend the useful life of NASA's constant communications infrastructure, supporting the astronauts around-the-clock aboard the International Space Station, supplying contact with the Hubble Space Telescope and transmitting the data from almost 40 science spacecraft studying Earth's environment and space.
The initiative is a data-rich new arm of the Documenting Hate project which collects and verifies hate incidents reported by both individual contributors and by news organizations. The Hate News Index will keep an eye out for false positives (casual uses of the word "hate" for example), striking a responsible balance between machine learning and human curation on a very sensitive subject. Hate events will be mapped onto a calendar in the user interface, though users can also use a keyword search or browse through algorithmic suggestions. For anyone who'd like to take the data in a new direction, Google will open sourced its data set, making it available through GitHub.
But the team discovered that using a technique called optogenetics, it was possible to truly erase the unpleasant memories. This technique involved the researchers using a virus to introduce genes into particular neurons in the brains of the mice that were involved in the "high-pitch" pathways. Once inside the cells, the genes result in the production of proteins which respond to light, allowing researchers to control the activity of the neurons. Taking mice with the fearful memories, the team exposed the neurons involved in the "high-pitch" pathway to low-frequency light -- an approach which weakens the connections between the neurons. The upshot was that the mice no longer appeared fearful when they heard the high-pitched tone.
