"A single company in Beijing's Haidian District has been selling the chips that generate as much as 80 percent of the world's cryptocoins."

"Last year the government cracked down on cryptocurrency trading and banned initial coin offerings. This year it's sent signals that it could seriously restrict mining."

"A February report by Bernstein Research estimated that the company might be generating profits of more than $3 billion per year, about the same as its much larger rival, Nvidia Corp. The report also suggested that Bitmain Technologies is probably one of the five biggest customers of the most advanced fabrication process offered by the Taiwanese chip giant Taiwan Semiconductor Manufacturing Co., which also counts among its clients Apple Inc. and Qualcomm Technologies Inc."

"Bitmain's big AI chip, Sophon -- named after the tiny supercomputer in the wildly popular Chinese sci-fi novel The Three-Body Problem -- came out five months behind Google's leading design, the Tensor Processing Unit. But while Google is the company to beat in all things AI, its chips are available only to customers of its cloud services, which are banned in China. That gives Jihan Wu a strong position at home."

"Smarter brains run on sparsely connected neurons." "The researchers analysed the brains of 259 men and women using neurite orientation dispersion and density imaging. This method enabled them to measure the amount of dendrites in the cerebral cortex, i.e. extensions of nerve cells that are used by the cells to communicate with each other. In addition, all participants completed an IQ test. Subsequently, the researchers associated the gathered data with each other and found out: the more intelligent a person, the fewer dendrites there are in their cerebral cortex."

"Using an independent, publicly accessible database, which had been compiled for the Human Connectome Project, the team confirmed these results in a second sample of around 500 individuals."

"Birds have primate-like numbers of neurons in the forebrain." "The brains of parrots and songbirds contain on average twice as many neurons as primate brains of the same mass, indicating that avian brains have higher neuron packing densities than mammalian brains. Additionally, corvids and parrots have much higher proportions of brain neurons located in the pallial telencephalon compared with primates or other mammals and birds. Thus, large-brained parrots and corvids have forebrain neuron counts equal to or greater than primates with much larger brains."

The Hawaiian islands are all made from the same mantle plume, which is like the blobs in a lava lamp, and it's in the middle of the tectonic plate -- not along the edge like most volcanos. If you look at the Hawaiian islands in "satellite view" on Google Maps, where you can see underwater mountains, you'll see a string of underwater mountains going towards Siberia. The line of underwater mountains is crooked, which means at one point, the plate just changed direction.

Whether you hear "Yanny" or "Laurel" depends on whether your brain focuses on high or low frequencies -- which can depend on the age of your ears and the audio equipment you are using.

450,000 women missed breast cancer screenings in the UK due to "errant algorithm." "The errant algorithm was in the National Health System's (NHS) breast cancer screening scheduling software, and remained undiscovered for nine years."

"'Tragically, there are likely to be some people in this group who would have been alive today if the failure had not happened,' K Health Minister Jeremy Hunt went on to tell Parliament. He added that based on statistical modeling, the number who may have died prematurely as a result was estimated to be between 135 and 270 women."

"Exactly how the 'algorithm failure' came about is clouded in controversy and contradictions. Right now, the NHS, PHE, and the software company Hitachi Consulting which maintains the software are pointing fingers at each other."

New York City Mayor Bill de Blasio has announced a task force to make algorithms free of bias. It's called the Automated Decision Systems Task Force. "'Fairness and equity are at the heart of human rights, and we are pleased to be partnering with leaders in and out of government to make sure City government itself aligns with these core values,' said Chair and Commissioner of the NYC Commission on Human Rights, Carmelyn P. Malalis."

"'We are excited to be the first city in the country bringing our best technology and policy minds together to understand how algorithms affect the daily lives of our constituents. Whether the city has made a decision about school placements, criminal justice, or the provision of social services, this unprecedented legislation gets us one step closer to making algorithms accountable, transparent, and free of potential bias,' said Speaker Corey Johnson."

Deep learning for gravitational lenses. "Until recently, scientists used large and sophisticated computer codes to analyze images. This required very large computations on superclusters and a significant amount of human intervention. But when Yashar Hezaveh, a NASA Hubble postdoctoral fellow at Stanford University’s Kavli Institute for Particle Astrophysics and Cosmology, and his team of researchers decided to apply computer vision and neural networks, everything changed."

"Another way to think about gravitational lenses is as funhouse mirrors, where the challenge is to remove the effect of mirror distortions and find the true image of the object in front of it. Traditional methods compare the observations against a large dataset of simulated images of that same object viewed in different distorted mirrors to find which one is more similar to the data."

"But neural networks can directly process the images and find the answers without the need for comparison against many simulations."

Someone wrote a Taylor Swift detector... in Swift (the programming language).

Well, Swift was used for an iOS client; Python was used for the machine learning.
