List of Inventions and Discoveries in Science and Technology
1. A new ink discovered by Scientists
An ink is discovered by the Council of Scientific and Industrial Research (CSIR) and National Physical Laboratory (NPL) to combat the problem of fake printing of passports and counterfeiting of currency notes. Let us tell you that it has a new security feature that will protect against duplicity.Important facts about new ink
- The ink consists of single excitable dual emissive luminescent pigment.
- The development of the ink is based on the concept of fluorescence and phosphorescence phenomena.The developed ink has features of changing the colour of pigment after the notes are printed.
- The ink shows white colour in ambient light. It turns into a red colour when it is exposed to UV light and when UV source is switched off it turns into a green colourThe reason behind the development of new ink is duplication of Rs 500 and Rs 2000 notes. As per RBI annual report (2018-19), the risk of duplication of Rs 500 and Rs 2000 notes is higher. Rs 500 duplication accounts for 12% and Rs 2000 to 21.9%.
2. Discovery of Paper SensorFor testing the freshness of milk, the scientists of an Indian Institute of Technology, Guwahati have developed a simple paper kit. It also tells about the pasteurisation that whether it is done well or not.
Important points about Paper Sensor
- Aided with a smartphone app, the kit will ensure that milk is consumed before it turns too sour.
- An indicator of milk quality is a milk enzyme namely Alkaline Phosphate or ALP, its presence even after pasteurisation indicates the presence of microbes that may not have been rendered inactive with pasteurisation.
- For preparing the detector, researches have used an ordinary filter paper.
- Further, the filter paper is cut into small discs by using office punch and impregnated with chemical probes that react with ALP.
- The 'probes' used are antibodies that specifically bind to ALP.
- When ALP comes into contact with the probe, it turns the disc of white paper into coloured.
- On paper discs when the colour changes are then photographed by a device or smartphone camera and images are processed to obtain corresponding colour values.
- These values are then compared with standard data stored in the phone.
- It not only detects the presence of ALP but also the amount of it in milk.

3. World's largest supercomputer SpiNNaker
SpiNNaker
SpiNNaker is the world's largest supercomputer that is designed to work in the same way as the human brain works.
Important points about SpiNNaker
- SpiNNaker is the Spiking Neural Network Architecture. In real-time, this machine can model several biological machines than any other device on the planet.
- It is capable of completing more than 200 million actions per second, with each other of its chips having 100 million transistors.
- No doubt this supercomputer is unique because it does not communicate by sending large amounts of information from point A to B through standard network like any other computer.
4. Hyperloop Technology
Hyperloop Technology
Hyperloop has a 'tube modular transport system' that will run free of friction. Or we can say it is a new form of ground transport. It is a new method with which people or objects can be moved rapidly and safely with efficiency anywhere in the world. It will also have minimal impact on the environment.
Hyperloop technology is the brainchild of Tesla founder Elon Musk, who showed its original design in a whitepaper in 2013. If this hyperloop system is successful in India, then probably the distance (1200 km) between Delhi and Mumbai can be covered in less than an hour. Do you know that it will cover 35 km in 5 minutes?
Important points about Hyperloop Technology
Supporters believed that it will be cheaper and faster than train or car travel.
- Less polluting than air travel.
- It is also quick and cheaper to build than traditional high-speed rail.
- Hyperloop will be used to take pressure off gridlocked roads that make travel between cities easier and potentially unlock the major economic benefits.
- India will get benefit from this technology. According to the proposals and feasibility, hyperloops are likely to start in five regions of India namely Delhi-Mumbai, Bengaluru-Thiruvananthapuram, Chennai-Bangalore, Mumbai-Chennai and a port also.

5. Apple's Smart Bottle
It has a stainless-steel, vacuum-insulated chug that keeps drinks cold for up to 24 hours. All users need to do is connect their smart bottles to the HidrateSpark App via Bluetooth. The LED smart sensor 'puck' glows to remind users to drink and tracks their water intake.
