 Difference Between RT-PCR and Antigen Test Reverse transcription polymerase chain reaction (RT-PCR) Under this, copies of a segment of DNA (deoxyribonucleic acid) are created using an enzyme called Polymerase. A fluorescent DNA binding dye called the “probe” is added to DNA, which shows the presence of the virus on a fluorometer. However, coronavirus is made of RNA (ribonucleic acid). Therefore to detect coronavirus, RNA is converted into DNA using a technique called reverse transcription. A ‘reverse transcriptase’ enzyme converts the RNA into DNA. Copies of the DNA are then made and amplified. For this test, throat or nasal swab is collected. The result of test comes in 4 to 8 hours. It is less faster but have more accurate results than rapid antigen test. This is test is most expensive of all those used for COVID-19. Initially, cost of test was capped at Rs 4500 but later removed. Rapid Antigen Test(RAT) These tests are designed to detect a specific protein in the virus that eli...

  What is Aquaponics and How Does it Work? Aquaponics is a combination of aquaculture, which is growing fish and other aquatic animals, and hydroponics which is growing plants without soil. Aquaponics uses these two in a symbiotic combination in which plants are fed the aquatic animals’ discharge or waste. In return, the vegetables clean the water that goes back to the fish. Along with the fish and their waste, microbes play an important role to the nutrition of the plants. These beneficial bacteria gather in the spaces between the roots of the plant and converts the fish waste and the solids into substances the plants can use to grow. The result is a perfect collaboration between aquaculture and gardening. Aquaponics is a big hope for sustainable organic crop production, aquaculture and water consumption. The fish waste is recycled and used for plant growth instead of throwing it in the ocean. The water is recirculated in a closed system lowering the consumption of this resource. ...

Smartphone tech in 2020: Cheaper foldable phones, more cameras and faster charging mobiles? The year 2019 was an exciting year for smartphone tech. We saw smartphones launching with different kind of notches and no-notch, the tradition from single, dual-camera setups to quad-camera modules, 12MP sensors to 48MP to 64MP to even 108MP smartphone cameras, and some 5G smartphones. Last year also witnessed up to 65W super-fast charging in commercial smartphones. Smartphone companies have already teased or given an idea about the kind of products they would launch this year. So what does 2020 have in store for us, the users?   Foldables for all? Last year, tech giants like Samsung and Huawei launched the Galaxy Fold and Mate X. These two smartphones when folded out offered a much larger screen estate and feature the best of internals and cameras from their respective premium/ flagship devices. Out of the two popular ones, only the Galaxy Fold made it to India with a whopping price t...

Top 5 Best Cars Which Rovers On Road Like Beast 1. 2019 Genesis 270 Many have failed and few have survived in challenging the Germans in compact luxury sport sedan supremacy. A newcomer to this competitive segment comes from an unlikely corner of the automotive world,  Hyundai ’s  luxury brand  Genesis . The all-new  G70  is the rookie of the year in a segment dominated by the likes of the  BMW 3 Series , the  Mercedes-Benz C-Class  and the  Audi A4 .

Tommy was impressed by the car’s interior quality and performance even from the base  4-cylinder , noting that "you really don’t need the 6-cylinder if you want a fun and quick sedan." Dwight said he "expecte...

Auto-Driver Cars are safer for pedestrain and car seaters also know how Autonomous vehicles are the wave of a rapidly approaching future that is already bringing increasing amounts of “smart” technology to cars and trucks, and could eventually make passengers of everyone in a vehicle. Experts say smart cars will make the roads exponentially safer by taking the automobile’s weak link — its human driver — out of the equation. Accidents would decline 90% by 2050, according to professional services company KPMG in a June report on the impact autonomous vehicles will have on the insurance industry. This can be accomplished, according to those involved in the research, because artificial intelligence and machine learning would make the computer “brain” driving autonomous cars and trucks far better at making decisions than humans, whose errors today cause 94% of car crashes. “The computer brain is programmed. You’re pretty sure reliably what it’s going to do. But the human brain? Who knows,” ...
