Brain Cells That Cool the Body
Posted by Karen Hurst in categories: biotech/medical, neuroscience
Summary: Researchers have identified a set of heat sensing neurons that prompt both nervous system and behavioral changes that help cool the body.
Source: NIH.
The body’s temperature is closely regulated. We sense temperature changes in the environment through specialized nerve cells in the outer layers of the skin. If we are too hot or too cold, our nervous system activates responses to help change our temperature. We can sweat to cool down or shiver to generate heat. Our blood vessels can constrict to conserve heat or expand to release heat. To avoid discomfort, we sometimes seek out different environments―choosing to go into an air conditioned room or sit by a heater.

UFO sighting: Flying saucer over China stops traffic
Posted by Karen Hurst in category: transportation
# UFO # China – UFO sighting: Flying saucer over China stops traffic : Commuters in a busy street of Guangzhou, China, were brought to a halt when they spotted a flying saucer hovering over the traffic.
The dashboard camera of one car snapped the flying saucer. The car pulled up behind crowds that were staring at the strange phenomenon. The footage that was taken from the car shows the driver coming to a stop, while people on the road were looking up with wide-open eyes and mouths.

Tech billionaires convinced we live in the Matrix are secretly funding scientists to help break us out of it
Posted by Andreas Matt in categories: computing, robotics/AI
Some of the world’s richest and most powerful people are convinced that we are living in a computer simulation. And now they’re trying to do something about it.
At least two of Silicon Valley’s tech billionaires are pouring money into efforts to break humans out of the simulation that they believe that it is living in, according to a new report.
Philosophers have long been concerned about how we can know that our world isn’t just a very believable simulation of a real one. But concern about that has become ever more active in recent years, as computers and artificial intelligence have advanced.

When her best friend died, she used artificial intelligence to keep talking to him
Posted by Albert Sanchez in categories: computing, robotics/AI
When the engineers had at last finished their work, Eugenia Kuyda opened a console on her laptop and began to type.
“Roman,” she wrote. “This is your digital monument.”
It had been three months since Roman Mazurenko, Kuyda’s closest friend, had died. Kuyda had spent that time gathering up his old text messages, setting aside the ones that felt too personal, and feeding the rest into a neural network built by developers at her artificial intelligence startup. She had struggled with whether she was doing the right thing by bringing him back this way. At times it had even given her nightmares. But ever since Mazurenko’s death, Kuyda had wanted one more chance to speak with him.
