About 40% of the world’s population is exposed to the risk of dengue and a large number of those people live in India, which has several virulent outbreaks of the disease especially in its monsoon months. Scientists have been tinkering with mosquito genes to find ways to control mosquito-borne disease like malaria and dengue and may have now created a genetically modified mosquito that can resist infection by the dengue virus and therefore cease to spread it.
Dengue is spread through the Aedes aegyptii mosquitos. Mosquitos that feed on the blood of an infected person pass the disease on when they subsequently bite a healthy person. Researchers from the Johns Hopkins Bloomberg School of Public Health have shown that the Aedes aegyptii’s natural ability to fight the dengue virus can be boosted to reject infection in the mosquito in the first place.
In research published in PLOS Neglected Tropical Diseases they describe manipulating a component of the Aedes aegyptii immune system called the JAK-STAT pathway, that regulates production of antiviral factors. The genetic modification resulted in fewer mosquitoes becoming infected. Most of the mosquitos that did get infected had very low levels of dengue virus in their salivary glands. However, the genetic modification did not make the mosquitos resistant to two other diseases that their also are capbale of carrying – Zika and chikungunya.
The team also found that the dengue-resistant mosquitoes live as long as the wild mosquitoes but produce fewer eggs, making it likely that the same mechanism that triggers the immune system plays a role in egg production.
Genetic modification of mosquitos for disease elimination is based on the theorro of “gene drives” that involve replacing the natural population of mosquitos with GM mosquitos that cannot spread the disease. A laboratory at Jalna in Maharashtra has been performing similar genetic experiments for dengue control. However, some scientists and ethicists hold the view that there can be unintended and unforseeable consequences of such large scale manipulations, some that maybe dangerous or even devastating.
We asked them and here's the verdict: Scotch is one of the #GiftsMenLove
A handy guide to buying a gift for a guy.
Valentine’s day is around the corner so men and women everywhere are racking their brains for the perfect present. Buying a gift for men though can be a stressful experience. Be it a birthday, celebration or personal milestone, many men and women find it difficult to figure out what their male friends or significant others want. That’s why TVF decided to perform a public service and ask the guys directly what they loved. So, the next time you’re running around to buy a gift for a man, just pick something from the list below and thank us later.
Watches: A watch can complete a man’s ensemble and quickly become a talking (or bragging) point at a party. If your man loves classics, a vintage HMT (if you can find one) with a metal strap should be your brand of choice. For fun-loving guys, try a Swatch watch with a pop-coloured leather strap or even a watch with Swarovski crystal studded dials from a variety of watchmakers. Fossil’s unconventional dials will delight a creative or artistic soul. Alternatively, the G-shock collection by Casio is reasonably priced, waterproof and perfect for those who love adventure sports. If your man is a fitness enthusiast, surprise him with an excellent fitness band from GoQii.
Whisky: A well stocked bar is every man’s pride and joy. Whisky, especially scotch is an extremely popular gift with men. It is a gift that can be displayed with pride and shared on occasions with friends and family. Scotch is any whisky (single malt or blended) that comes from Scotland, is usually aged for at least three years (often more) and distilled twice. Each region in Scotland produces whisky with a distinct flavor. Spirits from Islay, like Laphroaig, tend to have a strong peat flavor while single malts from Speyside tend to be lighter and sweeter. Connoisseurs will sing praises of the golden colour of blends like Johnny Walker or Black and White, and the smoky taste of Scotch whiskies like Black Dog. If your partner is truly mad about malts, go the whole hog and surprise him with a malt tour in Scotland - the ultimate whisky experience.
Jackets: For a more personal touch, a jacket can be quite an apt gift. A romantic-at-heart will love a traditional bandhgala while bike enthusiasts swear by their weather-worn leather jackets. Blazers are great day-to-night apparel, looking perfectly at home in the office or in a bar. You’ll be spoilt for choice when it comes to brands and designers: high street labels like Blackberry’s and Zara offer trendy outerwear at affordable prices. Custom made jackets like the ones from Raymond’s Made-To-Measure collection or the Bombay Shirt Company are also a great option, if you really want to get creative with the design.
Sunglasses: If your friend is a globetrotter, a smart pair of shades will delight him like nothing else. Whether he is sunbathing in the Maldives, chasing zebras in Tanzania or skiing in Courchevel, this travel accessory adds an instant glam quotient to almost every type of holiday. Recent sunglass trends have been a major throwback to retro shapes inspired from Hollywood films like Tom Cruise’s aviators from Top Gun, Steve McQueen’s Persols from The Thomas Crown Affair or the wayfarers sported by the lead actors in The Blues Brothers. You’ll find many variations at high street brands like H&M and Diesel but if you can stretch the budget, pick up a good quality pair from Burberry or Louis Vuitton. Better yet, buy a unisex design that you can borrow when your heart desires!
Headphones: Most guys love their music, whether their choice of genre is soft rock, hard metal or folk fusion. So, it makes sense that headphones are on the list of the most popular gifts loved by men. Make sure you know what you’re looking for when it comes to buying headphones. For style combined with comfort, Skull Candy headphones come in a fun palette of colours. For amazing sound quality and pumping bass, you can opt for Shure or Sennheiser; they may look basic but deliver on their audio capabilities. Audio-Technica headphones are also gaining a cult following among audiophiles for their excellent sound clarity. If your man listens to music while working out, get the Jabra Sports in-ear headphones which are made for the gym. Though it feels pragmatic, this gift will be treasured by all music lovers.
So, take a pick from this list and the guy you gift will be indebted to you for life! For more great gifting ideas, see here.
