E-cigarette users are possibly putting themselves at risk for developing heart disease, lung and bladder cancers, according to a new report. The findings, while preliminary, indicate that the devices — which use nicotine in an aerosol form and contain no tobacco — may not be as safe as previously assumed.
The study, conducted by researchers from the New York University School of Medicine, exposed mice to e-cigarette smoke for 12 weeks at a dose and duration equivalent to light e-cigarette smoking for 10 years in humans. By the end of the trial, the smoke had caused DNA damage in the animals' lungs, bladders and hearts, as well as limiting lung proteins and DNA repair.
Evidence points to the “almost unambiguous” conclusion that nicotine can convert to a carcinogen once inside the human body, said study author Moon Shong-tang, a professor of environmental medicine and pathology at NYU School of Medicine. “Nicotine is not as innocent as conventional wisdom thinks,” he said.
Currently, 18 million Americans smoke e-cigarettes. Sixteen per cent of those users are high school students, according to the report. Manufacturers have advertised the devices as a safer alternative to traditional tobacco products.
A slew of studies examining the long-term health consequences of vaping have been conducted, but the conclusions have been mixed.
In 2013, a trial found the practice to be as effective in helping smokers quit as using nicotine patches. Another study, published in August 2017, compared cancer potencies of e-cigarettes and tobacco smoke and found most vapours to have a cancer risk of less than 1 per cent of that from smoking.
Many are worried that the mild flavour of vapours will hook young people on nicotine, encouraging teenagers to smoke tobacco. In 2016, the US surgeon general Vivek Murthy called e-cigarette use among American youth a "major public health concern", citing a 900 per cent growth rate among high school students.
Mr Moon would not recommend vaping to non-smokers, in particular young people: “Don’t think a vapour is harmless.” As for cigarette smokers thinking about going electronic, Mr Tang hesitated. “We don’t know which one is more harmful,” he said.
This latest study is not, by itself, conclusive. Tumours cannot develop in 12 weeks—the length of the study — and if tobacco smoke-induced cancer is indeed a model for e-cigarette smoking-induced cancer, then meaningful human evidence will not be available for at least another decade.
In the meantime, scientists are turning to animal experiments, which may be able to provide further evidence as to the full-blown effects of e-cigarette smoking in about a year.
The design
The protective shell is covered in solar panels to make use of light and produce energy. This will drastically reduce energy loss.
More than 80 per cent of the energy consumed by the French pavilion will be produced by the sun.
The architecture will control light sources to provide a highly insulated and airtight building.
The forecourt is protected from the sun and the plants will refresh the inner spaces.
A micro water treatment plant will recycle used water to supply the irrigation for the plants and to flush the toilets. This will reduce the pavilion’s need for fresh water by 30 per cent.
Energy-saving equipment will be used for all lighting and projections.
Beyond its use for the expo, the pavilion will be easy to dismantle and reuse the material.
Some elements of the metal frame can be prefabricated in a factory.
From architects to sound technicians and construction companies, a group of experts from 10 companies have created the pavilion.
Work will begin in May; the first stone will be laid in Dubai in the second quarter of 2019.
Construction of the pavilion will take 17 months from May 2019 to September 2020.
Four reasons global stock markets are falling right now
There are many factors worrying investors right now and triggering a rush out of stock markets. Here are four of the biggest:
1. Rising US interest rates
The US Federal Reserve has increased interest rates three times this year in a bid to prevent its buoyant economy from overheating. They now stand at between 2 and 2.25 per cent and markets are pencilling in three more rises next year.
Kim Catechis, manager of the Legg Mason Martin Currie Global Emerging Markets Fund, says US inflation is rising and the Fed will continue to raise rates in 2019. “With inflationary pressures growing, an increasing number of corporates are guiding profitability expectations downwards for 2018 and 2019, citing the negative impact of rising costs.”
At the same time as rates are rising, central bankers in the US and Europe have been ending quantitative easing, bringing the era of cheap money to an end.
2. Stronger dollar
High US rates have driven up the value of the dollar and bond yields, and this is putting pressure on emerging market countries that took advantage of low interest rates to run up trillions in dollar-denominated debt. They have also suffered capital outflows as international investors have switched to the US, driving markets lower. Omar Negyal, portfolio manager of the JP Morgan Global Emerging Markets Income Trust, says this looks like a buying opportunity. “Despite short-term volatility we remain positive about long-term prospects and profitability for emerging markets.”
3. Global trade war
Ritu Vohora, investment director at fund manager M&G, says markets fear that US President Donald Trump’s spat with China will escalate into a full-blown global trade war, with both sides suffering. “The US economy is robust enough to absorb higher input costs now, but this may not be the case as tariffs escalate. However, with a host of factors hitting investor sentiment, this is becoming a stock picker’s market.”
4. Eurozone uncertainty
Europe faces two challenges right now in the shape of Brexit and the new populist government in eurozone member Italy.
Chris Beauchamp, chief market analyst at IG, which has offices in Dubai, says the stand-off between between Rome and Brussels threatens to become much more serious. "As with Brexit, neither side appears willing to step back from the edge, threatening more trouble down the line.”
The European economy may also be slowing, Mr Beauchamp warns. “A four-year low in eurozone manufacturing confidence highlights the fact that producers see a bumpy road ahead, with US-EU trade talks remaining a major question-mark for exporters.”

Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.

Engine: four-litre V6 and 3.5-litre V6 twin-turbo
Transmission: six-speed and 10-speed
Power: 271 and 409 horsepower
