  • No. Wall Street strategists’ predicting that the US government’s 10-year borrowing costs will climb above the 3 per cent mark in the coming year is as much a staple of the Christmas period as awkward office parties. This year the forecasts look more likely to be fulfilled, given a withdrawal of quantitative easing and the US tax cut. However, the seismic, secular forces pinning down both inflation and long-term bond yields remain in place and are still underestimated. The Federal Reserve will raise interest rates at least three times in 2018, but the 10-year yield will not breach 3 per cent.

Electromagnetic fields (EMF) are generated in the vicinity of power lines, mobile phones, mobile phone towers, broadcast towers and similar transmitters. Whether or not EMF can harm human health is a controversial issue. One EMF source to have received significant media attention is the high-voltage power line.

Various studies have comprehensively investigated power lines and cancers (such as leukaemia) to see if there is a causal link. Some researchers maintain that EMF generated by power lines have frequencies which are too low to influence living cells or harm DNA. Other researchers disagree. They suggest that EMF from power lines can cause significant changes in a biological system via electric fields induced in the body. Scientific standards have been developed to limit public exposure to power-frequency EMF, so that induced currents are below those that occur naturally in the body.

Two decades of debate

In 1979, researchers investigating childhood leukaemia in Denver, Colorado (USA) found an association between high-current configuration electrical wiring near the home and an increased risk of childhood cancer (Wertheimer and Leeper). This initial work, however, did not measure electromagnetic fields, relying instead on distances from power lines and the type of wiring. Since then, researchers across the world have investigated power lines. To date, serious limitations have been identified in nearly all studies on power lines and cancer. It has not been possible to confirm whether or not there is a real association between EMF and cancer.

UK findings are inconclusive

The National Radiological Protection Board (NRPB) in the United Kingdom recently released a report which found some evidence that EMF exposures higher than 0.4 microtesla (µT) are associated with a doubling of the risk of leukaemia in children. The review found no evidence of any increased risk of cancer in adults. However, the NRPB was careful to explain that no causal link was found, and recommended that further studies are needed. The evidence for the effect was inconclusive because the key studies in the review might have suffered from selection bias or random variation.

No proof of harm

Despite the evidence for an increased risk of leukaemia in children exposed to higher than 0.4µT of EMF, a range of experimental studies have failed to provide clear supporting evidence for the claim that EMF can be harmful to health, including:

  • An independent gauge of China’s manufacturing sector edged lower in November, suggesting an uptick in activity at state-run companies did not extend to smaller and privately-owned factories.

Victorian government policy

The Victorian Department of Human Services supports the view that current guidelines on EMF and power lines are adequate, since the EMF generated by power lines is well below the recommended maximum limit of exposure. However, it is advisable to avoid heavy exposure, if possible.

In 2008, Janah talked to a call center worker from Dharavi, India, the largest slum in South Asia, while working as a consultant. The worker said there were millions of unemployed villagers as talented as he was. "I thought, 'What if outsourcing could generate a few dollars for billions of people, rather than billions of dollars for a wealthy few'" Janah says. She went on to launch Samasource, a tech platform that connects impoverished women and youth with large corporations like Google, LinkedIn, and Microsoft to complete digital projects. To date, the non-profit has helped over 16,000 people rise above the poverty line and it recently launched SamaUSA, a domestic program for low-income students living in San Francisco.
What deserves to be mentioned the most is, Uber and Tesla Motors Inc did not make it to the list. "Both Uber and Tesla do innovate, but not at a sufficient level to feature in the Top 100 list of innovative organizations around the globe as measured by patent metrics of volume, success, globalization and impact. They neither have sufficiently large portfolios to qualify for inclusion with less than 100 granted inventions during 2010-2014," Stembridge said.
