An american source on this. Russia is way ahead of the USA on these, they were testing these in Syria, and there is no “WE CANT ARM ROBOTS!!” debate over there, they just go ahead and do it.

“In the context of increasing tensions with the United States, China and Russia have clearly made an agreement to expand their technological cooperation, with artificial intelligence playing a key role in their plans for the future,” a new CNA report finds.

Microsoft unveiled new tools for automatically generating computer code and formulas on Tuesday morning, in a new adaptation of the GPT-3 natural-language technology more commonly known for replicating human language.

Deepmind, Co-founder and CEO, Demis Hassabis discusses how we can avoid bias being built into AI systems and what’s next for DeepMind, including the future of protein folding, at WIRED Live 2020.

“If we build it right, AI systems could be less biased than we are.”

A new study contradicts the origin story of the Milky Way, suggesting that it evolved gradually over time rather than being formed by a giant collision.

# *Noise is commonly discarded, but identifying patterns in noise can be very useful.*

*Generalize the Hearst exponent by adding more coefficients in order to get a more complete description of the changing data. This makes it possible to find patterns in the data that are usually considered noise and were previously impossible to analyze.*

In everyday life, phase transitions usually have to do with temperature changes--for example, when an ice cube gets warmer and melts. But there are also different kinds of phase transitions, depending on other parameters such as magnetic field. In order to understand the quantum properties of materials, phase transitions are particularly interesting when they occur directly at the absolute zero point of temperature. These transitions are called "quantum phase transitions" or a "quantum critical points."

Such a quantum critical point has now been discovered by an Austrian-American research team in a novel material, and in an unusually pristine form. The properties of this material are now being further investigated.

Various insect species serve as valuable model systems for investigating the cellular and molecular mechanisms by which a brain controls sophisticated behaviors. In particular, the nervous system of Drosophila melanogaster has been extensively studied, yet experiments aimed at determining the number of neurons in the Drosophila brain are surprisingly lacking. Using isotropic fractionator coupled with immunohistochemistry, we counted the total number of neuronal and non-neuronal cells in the whole brain, central brain, and optic lobe of Drosophila melanogaster. For comparison, we also counted neuronal populations in three divergent mosquito species: Aedes aegypti, Anopheles coluzzii and Culex quinquefasciatus. The average number of neurons in a whole adult brain was determined to be 199380 ±3400 cells in D. melanogaster, 217910 ±6180 cells in Ae. aegypti, 223020 ± 4650 cells in An. coluzzii and 225911±7220 cells in C. quinquefasciatus. The mean neuronal cell count in the central brain vs. optic lobes for D. melanogaster (101140 ±3650 vs. 107270 ± 2720), Ae. aegypti (109140 ± 3550 vs. 112000 ± 4280), An. coluzzii (105130 ± 3670 vs. 107140 ± 3090), and C. quinquefasciatus (108530 ±7990 vs. 110670 ± 3950) was also estimated. Each insect brain was comprised of 89% ± 2% neurons out of its total cell population. Isotropic fractionation analyses did not identify obvious sexual dimorphism in the neuronal and non-neuronal cell population of these insects. Our study provides experimental evidence for the total number of neurons in Drosophila and mosquito brains.

A brain–computer interface enables rapid communication through neural decoding of attempted handwriting movements in a person with paralysis.

Some of the most devastating health effects of a stroke or heart attack are caused by oxygen deprivation in the brain. Now, researchers at Massachusetts General Hospital (MGH) have identified an enzyme that may naturally protect the brain from oxygen deprivation damage, which could be a potential drug target to prevent issues arising from strokes or heart attacks.

Like many scientific breakthroughs, the new discovery came about while investigating something else entirely. The team was looking into a study from 2005 that found that a state of “suspended animation” could be induced in mice by having them inhale hydrogen sulfide. In the new study, the researchers set out to investigate the longer-term effects of that exposure.

The team exposed groups of mice to hydrogen sulfide for four hours a day, for five consecutive days. The suspended animation-like state followed, with the animals’ movement slowing and body temperatures dropping.
