China’s Cobalt is a Secret Weapon in the Race to Dominate Electric Cars
"China is even more dominant in the production of cobalt chemicals needed to make batteries than Congo is in cobalt mining. According to data from Darton Commodities Ltd., China accounts for more than 80 percent of the production of cobalt chemicals.

“China controls a massive proportion of the world’s cobalt sulphate,” says George Heppel, an analyst at consultancy CRU Group in London. “Aside from one chemical refinery in Finland, they control pretty much the entire world’s cobalt chemical refining capacity.”"

Unlocking this information from medical language makes a variety of common medical use cases easier and cost-effective, including: clinical decision support (e.g., getting a historical snapshot of a patient’s medical history), revenue cycle management (e.g., simplifying the time-intensive manual process of data entry), clinical trial management (e.g., by identifying and recruiting patients with certain attributes into clinical trials), building population health platforms, and helping address (PHI) requirements (e.g., for privacy and security assurance.)

“We’re able to completely, automatically look inside medical language and identify patient details,” including diagnoses, treatments, dosage and strengths, “with incredibly high accuracy,” said Matt Wood, general manager of artificial intelligence at Amazon Web Services.

During testing, the software performed on par or better than other published efforts, and can extract data on patients’ diseases, prescriptions, lab orders and procedures, said Taha Kass-Hout, a senior leader with Amazon’s health-care and artificial intelligence efforts.

Users upload health records to Amazon’s cloud service, where they can run the text-processing software. Amazon’s algorithms analyze text for specific types of data and return the results in an organized format, similar to a spreadsheet.

600K bitcoin miners shut down in last 2 weeks, F2Pool founder estimates • CoinDesk
Wolfie Zhao:
<p>Between 600,000 and 800,000 bitcoin miners have shut down since mid-November, amid declines in price and hashrate across the network, according to the third-largest mining pool.

In an interview with CoinDesk, Mao Shixing, founder of F2pool, said his firm’s estimate takes into account the total network hashrate drop and the average hash power of older mining machines that are having a hard time generating profits.

According to <a href="https://www.blockchain.com/charts/hash-rate?timespan=30days&daysAverageString=7">data from blockchain.info</a>, the bitcoin network’s entire hashrate, which captures the aggregated computing power on the world’s first blockchain, has dropped from around 47m tera-hashes per second (TH/s) on Nov. 10 to 41m on Nov. 24 – an almost 13% decline.

Mao explained most miners that may have halted operations are likely those using older models, such as the Antminer T9+ made by Bitmain and AvalonMiner 741 by Canaan Creative. These miners have an average hash power of around 10 TH/s and are estimated to be losing money right now, according to F2pool’s <a href="https://www.f2pool.com/miners">miner revenue index</a>…

…Stepping back, Mao said there are multiple factors that contributed to the shakeout among miners, including the recent market decline that followed the bitcoin cash hard fork on Nov. 15; an increase in electricity costs in China; and the fact that Chinese manufacturers are still racing to upgrade their products, making older machines increasingly uncompetitive.</p>


The bitcoin cash hard fork increasingly looks like a key reason for the price crash of the past couple of weeks, by forcing some miners to liquidate large amounts of bitcoin in order to buy new kit. The question is whether once they have new kit they will find anyone interested in the processing they have to offer.

Bitcoin mining firm Giga Watt declares bankruptcy owing millions • Coindesk
Yogita Khatri:
<p>US-based bitcoin mining firm Giga Watt has declared bankruptcy with millions still owed to creditors.

The firm filed for Chapter 11 bankruptcy at a court in the Eastern District of Washington on Monday, revealing that it still owes its biggest 20 unsecured creditors nearly $7m in court documents seen by CoinDesk.

Creditors include the utilities provider in its Douglas County base, having a claim of over $310,000, and electricity provider Neppel Electric, which is owed almost half a million dollars.

Giga Watt has estimated assets worth less than $50,000, whereas estimated liabilities are in the range of $10–50m, according to the court documents.

“The corporation is insolvent and unable to pay its debts when due,” read the minutes of a special meeting of the shareholders of Giga Watt, which was held on Nov. 18. “The corporation and its creditors would best be served by reorganization of the corporation under Chapter 11 of the Bankruptcy Code.”

The meeting was called by Andrey Kuzenny, a director owning more than 10% of the mining firm.

Giga Watt was founded by bitcoin miner Dave Carlson with the plan being to open up the industry to smaller scale miners by creating customized mining “pods” along with a cheap and stable electricity supply and round-the-clock maintenance at a facility in central Washington.

As part of a plan to allow investors to buy a stake in the company’s services, it held an initial coin offering (ICO) in May 2017 that raised about $22m-worth of cryptocurrency at the time.

However, this January, a group of plaintiffs sued Giga Watt for allegedly conducting an unregistered securities offering.</p>

Oof. The fallout continues.
