This was the first part in an interview series with Scott Aaronson — this one is on quantum computing — other segments are on Existential Risk, consciousness (including Scott’s thoughts on IIT) and thoughts on whether the universe is discrete or continuous.

Interview with Scott Aaronson — covering whether quantum computers could have subjective experience, whether information is physical and what might be important for consciousness — he touches on classic philosophical conundrums and the observation that while people want to be thorough-going materialists, unlike traditional computers brain-states are not obviously copyable. Aaronson wrote about this his paper ‘The Ghost in the Quantum Turing Machine’ (found here https://arxiv.org/abs/1306.0159). Scott also critiques Tononi’s integrated information theory (IIT).

The brain surgery that uses sound instead of scalpels.

“We wanted to be more precise here and identify the region and the cells that are responsible for pain unpleasantness,” Scherrer tells Inverse. “We thought if we could find the center, or the cells in the brain that make pain unpleasant, perhaps acting on these cells could be a good strategy to reduce pain in chronic pain patients.”

It’s already established that the amygdala plays a role in the emotional component of pain, but this team actually found the exact cells in the amygdala responsible for those unpleasant pain messages by using a “miniscope,” a tool created by Schnitzer, and observing how mice responded to painful stimuli.

When mice in their experiment were exposed to a drop of scalding water, a given a pinprick, or asked to run along unpleasantly hot tracks, these cells in the amygdala were highly active. Importantly, Schnitzer adds, they didn’t light up when the mice were exposed to other stimuli like sugar water or a bad smell. “Every time mice were unpleased with the stimulation, we saw that these cells were turned on,” he adds.

Neuroscientists Pinpoint Cells In The Amygdala Where Pain Hurts : Shots — Health News Researchers have pinpointed the neurons that give pain its unpleasant edge. By turning these neurons off in mice, the scientists relieved the unpleasantness of pain without numbing sensation.

As I look back on the year, I am also thinking about the specific areas I work on. Some of this is done through our foundation but a lot of it (such as my work on energy and Alzheimer’s work) is not. What connects it all is my belief that innovation can save lives and improve everyone’s well-being. A lot of people underestimate just how much innovation will make life better.

Here are a few updates on what’s going well and what isn’t with innovation in some areas where I work.

Bill Gates looks back on 2018, and shares a few thoughts on what’s going well and what isn’t with innovation in some specific areas that he works on.

New research published in the journal Nature Medicine has described the results of a five-year study into the association between a breakdown of the blood-brain barrier and the onset of cognitive impairment. The study suggests leaky capillaries in the brain can act as an early biomarker of cognitive decline, and a new drug being developed for stroke patients may be an effective treatment.

For the first time, scientists have used rapid 3D printing technologies to create a spinal cord. The team at UC San Diego then put neural cells in it and implanted it into rats, who walked again.

To be approved, government figures have shown.

More than 17,000 people have died in the past seven years while waiting for their disability benefit claim to be approved, according to figures obtained by The Independent.

The claimants, who were in the process of claiming a type of benefit named the Personal Independence Payment (PIP), were reportedly suffering from a mixture of terminal illnesses and disabilities, including anxiety and depression while they waited for their benefits to be paid.
