Teammate edges Power for pole in Indycar

  Teammate edges Power for pole in Indycar Australia's Will Power will start from second on the grid for the Indycar Grand Prix of Alabama on one of his favourite tracks. Teammate Josef Newgarden has denied Australia's Will Power a record fifth pole position for the Indycar race in Birmingham, Alabama.American Newgarden, who used a win at Barber Motorsports Park a year ago as a catapult to the 2017 IndyCar championship title, edged out Power by just 0.0128s to start from pole in Sunday's Indy Grand Prix of Alabama.Power, a two-time winner at Barber, will start on the front row for the eighth time in the 2.3 milepemanent road track's nine-race history.

Through it's IoT Alliance , it moves into blockchain technology with strategic partners. By creating a blockchain ‘smart contract’ record, a product can be tracked from it’s production, through to warehouse, shipment and all the way to Unilever and IBM Pilot Blockchain Digital Ad Supply Chain.

IBM Blockchain Platform is an enterprise-ready blockchain application development solution powered by Hyperledger Composer and ready to transform your industry.

If you're checking out engagement rings or earrings in one of Helzberg Diamonds's 200 stores later this year, your phone should be able to tell you exactly where that jewelry came from.

Through an alliance called TrustChain, IBM, Helzberg and companies involved with mining and refining will be able to track gems and precious metals from their origins all the way to the mall. It's based on a technology called blockchain that's outgrown its origin -- the way to record transactions with the bitcoin cryptocurrency -- into a tool to cement all kinds of transactions and digital data into a shared, tamperproof, permanent record.

The result in the case is a way that a host of companies can track finished jewelry in a store back through its entire history, said Jason Kelley, IBM's general manager of blockchain services. That'll let you be sure an item has the history and value you think it has -- particularly important if you want to sell it yourself. You and law enforcement also can have some faith that your necklace isn't tied to sordid aspects of the trade such as corruption, terrorist financing, slavery and other human rights abuses.

"We have a need in our industry for truth and greater trust," Kelley tells me.

Blockchain, designed to hard-wire that trust into digital records of what's going on, has the potential to revolutionize not just commerce but also voting, home buying, hiring, online advertising and other fields. But there's a long way between today's reality and that promise. Blockchain is more likely to be seen in pilot projects than the actual systems that govern our lives, and integrating it isn't simple.

Five years after Rana Plaza, Bangladesh still needs $1.2 billion fix

  Five years after Rana Plaza, Bangladesh still needs $1.2 billion fix Five years ago this week, just after thousands of garment workers had settled in behind their sewing machines, a poorly built eight-story Bangladeshi factory complex called Rana Plaza buckled and collapsed. More than 1,130 people, mostly young women, died; 2,500 were injured.In the years since the worst disaster ever in the apparel industry, Bangladesh has become a laboratory for testing factory safety. Western brands and retailers that source low-priced clothing there have inspected 2,300 active factories and pressured suppliers to make real improvements. Dozens of shoddily built facilities have closed altogether.

Watchlist. Track stocks and ETFs. Regardless of where IBM ends up investing, the addition of a major tech company to the blockchain startup world is an important sign of the latter's growth and success.

IBM - aka ‘Big Blue’ - together with Walmart, Nasdaq-listed Chinese retailer JD.com and Tsinghua University are to collaborate on a food safety alliance in China using the blockchain to achieve greater safety within the food supply chain and improve food tracking , traceability and transparency.

The TrustChain alliance includes Asahi Refining and LeachGarner, which refine and supply precious metals; Richline Group, which makes jewelry; and Helzberg Diamonds, which sells the products. Blockchain networks offer more utility with more members in an alliance, though, so Kelley says alliance members plan to expand.

TrustChain has graduated from its pilot stage, but getting it to work isn't simple. At Richline, more than 100 people from accounting, information technology and business operations were involved, according to Kelley.

The hard part of blockchain

"The technology is pretty easy," Kelley says. "What's tough is getting the businesses and the business processes, the different players and personalities, together to execute in a single consortium."

The benefits can be significant, though. Blockchain also could help remove uncertainty that clouds other transactions. Is that really fair trade coffee? Is that a counterfeit Louis Vuitton purse? Did those running shoes come from a sweatshop? No wonder there are blockchain programs to assure the authenticity and provenance of diamonds.

A lot of blockchain work involves digital assets -- data that can be recorded directly on a blockchain. It's trickier with physical assets like diamonds, pharmaceuticals, high-end fashion products and jewelry, though. There have to be procedures to ensure nobody switches out genuine article and switches in a fake that assumes its identity on the blockchain.

Molecular verification for blockchain

Authentication options are an active area of improvement, though, for example with a "molecular watermark in a certain place" in a product, Kelley says. Naturally, IBM is working on this verification technology.

"Blockchain doesn't solve that -- the original recording of the physical asset," Kelley says. "We can take a picture at molecular level to verify an object is what we think it is. That is then put into the blockchain."

So the trust isn't perfect. But to be useful, blockchain doesn't have to be perfect. It just has to be better.

NASA launches InSight spacecraft to Mars to dig down deep .
NASA has launched a spacecraft to land on Mars and explore the mysterious insides of the red planet.&nbsp;In a twist, NASA launched the Mars InSight lander from California rather than Florida's Cape Canaveral. It was the first interplanetary mission ever to depart from the West Coast, drawing pre-dawn crowds to fog-socked Vandenberg Air Force Base and rocket watchers down the California coast into Baja.
