Battling disease

This video explains how mosquitoes can be used to fight malaria (in two words, genetic engineering)

We haven't adopted the technology yet because it might lead to unintended consequences.


Mosquitoes might quite possibly be one of mankind's most deadliest threat. Out of 3.2 billion people globally vulnerable to malaria, 214 million cases were reported in 2015, resulting in around 438,000 deaths. India contributes a jaw-dropping 96 per cent of malaria cases and 98 per cent of malaria deaths in the world. Only recently, the Delhi government was pulled up over 19 deaths caused by chikungunya.

Last year, India flirted with the idea of introducing genetically modified mosquitoes to combat the large number of diseases the insects spread. A new video on the YouTube channel Kurzgesagt attempts to explain how these GMO mosquitoes, which are resistant to the malaria parasite because an anti-body gene is added to their genetic structure, could help us eradicate malaria.

"The mosquitoes would probably benefit from it. They don't have anything to gain by carrying parasites." This could also be extended to other disease-carrying organisms.

So why haven't we done this yet? "Once we do it, there is no going back, so we have to get it right, otherwise there will be unwanted consequences." The risks involved mean that any large scale application of the technology is at least five years away.

To those who are wondering whether it wouldn't be simpler to exterminate the entire mosquito population, here is a short "what if" video explainer on the subject.

Bringing the glamour back to flying while keeping it affordable

The pleasure of air travel is back, courtesy of an airline in India.

Before dinner, fashionable women would retire to the powder room and suited-up men would indulge in hors d’oeuvres, surrounded by plush upholstery. A gourmet meal would soon follow, served in fine tableware. Flying, back in the day, was like an upscale party 35,000 feet up in the air.

The glamour of flying has been chronicled in Keith Lovegrove’s book titled ‘Airline: Style at 30,000 feet’. In his book, Lovegrove talks about how the mid-50s and 60s were a “fabulously glamorous time to fly in commercial airlines”. Back then, flying was reserved for the privileged and the luxuries played an important role in making travelling by air an exclusive experience.

Fast forward to the present day, where flying has become just another mode of transportation. In Mumbai, every 65 seconds an aircraft lands or takes off at the airport. The condition of today’s air travel is a cumulative result of the growth in the volume of fliers, the accessibility of buying an air ticket and the number of airlines in the industry/market.

Having relegated the romance of flying to the past, air travel today is close to hectic and borderline chaotic thanks to busy airports, packed flights with no leg room and unsatisfactory meals. With the skies dominated by frequent fliers and the experience having turned merely transactional and mundane, is it time to bid goodbye to whatever’s enjoyable in air travel?

With increased resources and better technology, one airline is proving that flying in today’s scenario can be a refreshing, enjoyable and affordable experience at the same time. Vistara offers India’s first and only experience of a three-cabin configuration. At a nominal premium, Vistara’s Premium Economy is also redefining the experience of flying with a host of features such as an exclusive cabin, 20% extra legroom, 4.5-inch recline, dedicated check-in counter and baggage delivery on priority. The best in class inflight dining offers a range of regional dishes, while also incorporating global culinary trends. Other industry-first features include Starbucks coffee on board and special assistance to solo women travellers, including preferred seating.

Vistara’s attempts to reduce the gap between affordability and luxury can also be experienced in the economy class with an above average seat pitch, complimentary selection of food and beverages and a choice of leading newspapers and publications along with an inflight magazine. Hospitality aboard Vistara is, moreover, reminiscent of Singapore Airlines’ famed service with a seal of Tata’s trust, thanks to its cabin crew trained to similarly high standards.

The era of style aboard a ‘flying boat’ seems long gone. However, airlines like Vistara are bringing back the allure of air travel. Continuing their campaign with Deepika Padukone as brand ambassador, the new video delivers a bolder and a more confident version of the same message - making flying feel new again. Watch the new Vistara video below. For your next trip, rekindle the joy of flying and book your tickets here.
