Scientists have determined that formaldehyde emissions from chemical and oil refineries and vehicles play a significant role in creating the smog and haze in China. After recent improvements in air quality by limiting use of coal, the focus now shifts to other sources. 

Scientists say the formaldehyde emissions combine in a chemical reaction with the sulfur dioxide released from burning coal to create substances that create the smog and haze over Beijing and other cities.

A look at the role that David Cameron played in the Brexit vote. Cameron did this by promising to hold a referendum to assuage hard line Tories within his Conservative Party in Britain who feared that the right wing Independence Party of Nigel Farage would cut into the Tory vote and hand the 2015 election over to the Labour Party. Cameron made the pledge in 2013. The Brexit vote referendum happened in June 2016 with a slight margin for the "Leave" vote as voters shifted to an anti-establishment vote, and a wave of immigration from Africa and Arab countries in conflicts into Europe created fears of uncontrolled immigration. Both were factors that had little to do with Britain's place in Europe over decades in post war Europe, and not permanent shifts in sentiment. Cameron agreed because he thought the would lead to a result favoring the Remain Vote to stay in the European Union. Cameron badly miscalculated leading to the mess Britain is in today with no clear path forward and negative effects on the economy of Britain. The Labour Party now favors a second referendum as voter sentiment again shifts following the failure of the Theresa May Conservative government to lead in the way forward, and splits in the Conservative Party. Immigration from Arab countries and Africa is now restricted and down to a small trickle. The problems generated by Brexit for the economy, Northern Ireland, business uncertainty, and second thoughts among pro-Brexit supporters, are leading to a rethink of the course set by the referendum based on a temporary shift in sentiment. ...

The split of the global internet into three with the emergence of a closely monitored internet in China, and Google developing the Dragonfly version to enter China in cooperation with the government. The European Union will have its own version that rivals the U.S. with its own regulations and rules. Each has its large home base. A fourth base is in South Asia where a home grown internet is still to develop. The split will be based on home versions such as Baidu in China and Google, Bing, Safari in the U.S. and the EU version with different rules for privacy and protection. Openness, limits, regulation, government rules and control in home countries, will characterize the patterns in each. This Editorial Board article in NYT says the U.S. version may not end up being the best.

In a new twist drugmaker AbbieVie will bring out less costly versions of Humira in Europe where its patents have expired and still keep the U.S. market at higher Humira prices using a thicket of patents. Reports show pharmaceutical drug pricing as a major issue in U.S. midterm elections. Biologic drugs are costly. In this case Humira will sell at a 10-20% discount in Europe. Abbie Vie countered by getting hundreds of new patents in the U.S. to continue selling at high prices.

The Russian economy gets an exceptional boost with the behaviour of ruble currency separating from the oil prices. Russia benefits from higher oil prices at the same time as it benefits from a weaker ruble. The ruble has declined 15% since April after more sanctions on Russia. The revenue earned in dollars converts into more rubles for imports and other financing for the Russian economy. At the end of 2017 a barrel of oil brought in 3,835 rubles for Russian sellers, when converted into rubles from U.S. dollars. In October 2018 each barrel brings in 5,262 rubles, an increase of 40%.  Russia deftly managed its emerging market crisis with lower ruble following the crisis in Ukraine by adapting its economy to a lower ruble, lowering imports and using import substitution. Initially Russia split with OPEC and Saudis to produce oil all out, but by 2018 with the Saudi economy hurting and Russia feeling the impact of lower oil prices, an OPEC agreement with Russia has pushed prices higher with production limits. Earlier adaptation by 2016 to the lower ruble, further decline of the ruble in 2018 with sanctions by U.S. for Russian interventions in other countries including the U.S. election meddling, have combined with higher oil prices to strengthen the Russian economy. Russian private and government debt held by foreign investors has fallen since 2016 to 32% in the first quarter, according to Societe Generale. This means Russia is less sensitive to foreign investor exit from the country with political and economic winds changing. Russia's current account surplus increased to $18.3 billion in the first quarter of 2018, up from $14.6 billion in the prior quarter. A weaker ruble has translated into more inflation which reached 5.5% at the end of 2017, above 4% target. Russia's central bank made quarter point increase to 7.5% for the interest rate in September 2017. Overall the management of the emerging market crisis since 2016 as Russia responded to NATO expansion and adopted its own policy is remarkable considering the damage from earlier emerging market crises. Countries such as Argentina, Brazil, and even India are feeling the impact of the current emerging market crisis, each with its own version of the crisis- Argentina with dollar denominated debt, Brazil lacking money in the budget after high pensions, and India with higher energy costs and weaker rupee.   ...

As part of the European Union Brtiain could not shape its own trade deals since the 1970's. The current Brexit standoff leaves little option of changing this. The new Department of International Trade is unlikely to accomplish much even with 400 staffers and a new trade negotiator hired from New Zealand. Britain is likely to remain in the EU trading bloc customs area for many years under the standoff with EU. Countries will wait till Britain finalizes its trade deal with the EU under Brexit. It took Canada 7 years to achieve a trade deal with EU. 

Brexit uncertaintly, split in Conservative Party and Labour Party's agreeing to a second referendum on Brexit mean little progress on trade deals for Britain.

Infosys built its business on outsourcing by U.S. business. President Trump's executive order to "Buy American, Hire American" is changing the way it does business. Infosys plans to hire 10,000 software engineers in the U.S. by 2019. 

A big change is also coming from new technologies in computing that require small teams to work side by side with customers. This is best done by having software engineers in U.S. offices and not engineers in offices thousands of miles away. A president of Infosys says this is the new face of computing at Infosys.

The Economist magazine expresses the view in this editorial that Britain is likely to shift to the "greatest extension of economic democratic rights that this country has ever seen" under Labour party because of what it calls the "grotesque"  uncertainty situation created by Brexit and years of austerity under the Conservatives, split in Conservatives under Theresa May. Britain is getting the debate of ideas that the referendum has led to and the possibilities for reshaping Britain under Labour after the "grotesque folly" of Brexit.
