Exclusive: Humans placed in suspended animation for the first time | New Scientist

EPR involves rapidly cooling a person to around 10 to 15°C by replacing all of their blood with ice-cold saline. The patient’s brain activity almost completely stops. They are then disconnected from the cooling system and their body – which would otherwise be classified as dead – is moved to the operating theatre. A surgical team then has 2 hours to fix the person’s injuries before they are warmed up and their heart restarted.

The world’s first Gattaca baby tests are finally here – MIT Technology Review

Handed report cards on a batch of frozen embryos, parents can use the test results to try to choose the healthiest ones. The grades include risk estimates for diabetes, heart attacks, and five types of cancer.

According to flyers distributed by the company, it will also warn clients about any embryo predicted to become a person who is among the shortest 2% of the population, or who is in the lowest 2% in intelligence.”

Brain Mapping Tech Inflates Tissue 20x to Reveal Remarkable Detail

“ExM can be used to explore neural connectivity in 3D with spatial precision sufficient for resolving individual synaptic connections,” the authors say. “If you could reconstruct a complete brain circuit, maybe you could make a computational model of how it generates complex phenomena like decisions and emotions,” says Boyden, “you could potentially model the dynamics of the brain.”

5 Neuroscience Experts Weigh in on Elon Musk’s Mysterious “Neural Lace” Company – IEEE Spectrum

What can we expect from Neuralink, the new Elon Musk company devoted to brain-computer interfaces?

This is very exciting technology, and I am fascinated by what it could mean.  Here Eliza Strickland asks 5 neuroscience types what they implications and limitations could be.

“Scientists at The Scripps Research Institute (TSRI) have developed the first stable semisynthetic organism — a bacterium with two new synthetic bases (called X and Y) added to the four natural bases (A, T, C, and G) that every living organism possesses. Adding two more letters to expand the genetic alphabet can be used to make novel proteins for new therapeutics, according to the researchers.”

Scientists identifiy the first evidence of ‘virtual particles’ hopping in and out of existence, which were first predicted in the 1930s | It’s Interesting

The theories of QED suggest that the universe is full of “virtual particles,” which are not really particles at all. They are fluctuations in quantum fields that have most of the same properties as particles, except they appear and vanish all the time. Scientists predicted the existence of virtual particles some 80 years ago, but we have never had experimental evidence of this process until now.

Neuroscientists Say Simple Mathematical Logic Underlies Complex Brain Computations | Neuroscience | Sci-News.com

“Many people have long speculated that there has to be a basic design principle from which intelligence originates and the brain evolves, like how the double helix of DNA and genetic codes are universal for every organism,” Dr. Tsien said.

“We present evidence that the brain may operate on an amazingly simple mathematical logic.”

Mind-Controlled Nanobots Used to Release Chemicals in Living Cockroaches

The authors believe that future designs of their technology could be used to automatically trigger drug release in humans when required.

The algorithm can be trained to track brain states that underlie ADHD or schizophrenia or otherwise be modified to suit your needs, explains study author Sachar Arnon to New Scientist. For example, if EEG detects signs of a burgeoning depressive episode, it could trigger DNA robots to expose anti-depressants briefly to counteract symptoms before they become full-blown. This way, the brain isn’t perpetually bathed in mind-altering drugs even when they’re not needed.

It’s a futuristic idea, and lots of things still need to be ironed out.

The Extraordinary Link Between Deep Neural Networks and the Nature of the Universe

Artificial neural networks are famously based on biological ones. So not only do Lin and Tegmark’s ideas explain why deep learning machines work so well, they also explain why human brains can make sense of the universe. Evolution has somehow settled on a brain structure that is ideally suited to teasing apart the complexity of the universe.

This work opens the way for significant progress in artificial intelligence. Now that we finally understand why deep neural networks work so well, mathematicians can get to work exploring the specific mathematical properties that allow them to perform so well. “Strengthening the analytic understanding of deep learning may suggest ways of improving it,” say Lin and Tegmark.

Deep learning has taken giant strides in recent years. With this improved understanding, the rate of advancement is bound to accelerate.
