Preparations are underway for first-ever trip to the Sun, a new resupply mission arrives at the International Space Station, and our Dawn spacecraft captures close-up photos of dwarf planet Ceres — these a few of the stories to tell you about This Week at NASA!
German automaker Daimler is the 1st foreign company licensed to test its autonomous vehicles in Beijing.
July 6 (UPI) — German automaker Daimler is the first foreign company licensed to test its autonomous vehicles in Beijing, the company announced on Friday.
With the certification, the maker of Mercedes-Benz vehicles can begin road tests of self-driving cars in Beijing, “a metropolis with unique and complex urban traffic situations,” a company statement said.

Interstellar travel one of the most moral projects? “one of the most moral projects might be to prepare for interstellar travel. After all, if the Earth becomes inhabitable—whether in 200 years or in 200,000 years—the only known civilization in the history of the solar system will suddenly go extinct. But if the human species has already spread to other planets, we will escape this permanent eradication, thus saving millions—possibly trillions—of lives that can come into existence after the demise of our first planet.”
The Red Planet is a freezing, faraway, uninhabitable desert. But protecting the human species from the end of life on Earth could save trillions of lives.

The workings of memory and learning have yet to be clarified, especially at the neural circuitry level. But researchers at Uppsala University have now, jointly with Brazilian collaborators, discovered a specific brain neuron with a central role in learning. This study, published in Neuron, may have a bearing on the potential for counteracting memory loss in Alzheimer’s disease.
When a person with dementia forgets having just eaten dinner, it is due to hippocampus damage. In contrast, the same person can describe in vivid detail a fishing trip to Norway 40 years ago. Both cases entail the use of episodic memory, the brain’s storage of events in which we have been personally involved. Dementia diseases impair the ability to form new memories, especially of events since the onset of the disease.
Researchers at Uppsala University have now, jointly with Brazilian colleagues, found certain neurons in the brain that play a crucial part in learning. The same research group had previously discovered ‘gatekeeper cells’ or, in technical parlance, OLM (Oriens-lacunosum moleculare) cells. These are located in the hippocampus, the brain area known to be active in forming new memories. The new findings from Klas Kullander’s research group show that OLM cells’ activity affects the encoding of memories in the brain.
