                                          What Is RFID? Radio-Frequency Identification is the use of radio waves to read, capture, and interact with information stored on a tag. Tags are usually attached to objects, and can be read from several feet away. Furthermore, the tag doesn’t always have to be in the direct line-of-sight to initiate interaction. An RFID tag is an easy way to assign a unique identity to an object. Additionally, they do not need an internal power source, while a tag can be as small as a grain of black pepper. Meaning they are easily embedded almost anywhere — hence their popularity. How Does RFID Work? A basic RFID system comprises two parts: the tag, and the reader. Tag The RFID tag has an embedded transmitter and receiver. The actual RFID component contained in a tag has two parts: an integrated circuit for storing and processing info...

  Java is one of the best programming languages for development. The popularity and usage of Java are still increasing even after two decades which is a big time for any Programming language. There are only a few programming languages which seem hard to get replaced and Java is one of them.Here are 5 reasons why java is one of the best programming language. Why is Java the best programming Language? 1. Object Orientation Java is an object-oriented programming language that supports all principles like Data Abstraction, Encapsulation, Polymorphism, Overloading, Overriding, and Inheritance. Which makes it as powerful as C++. We all know C++ is the extended version of C programming. Thus, it makes Java better than C programming.   2. Rich API Another big reason to learn Java is it’s Rich API. Java provides API for almost everything you need in development like I/O, networking, utilities, XML parsing, database connection etc. Whatever left ...

It is one thing to come up with a wacky idea for transforming our cities or constructing the world’s greatest supervillain evil lair; another to have the expertise and inclination to actually research and build one for real. A new research project coming out of the Netherlands quite handily ticks both boxes. Developed by researchers at the Maritime Research Institute Netherlands (MARIN), their idea is to develop giant artificial islands like today’s floating docks — only on a much, much bigger scale. Like, several miles wide bigger. And they may just pull it off, too. “With the world’s increasing population there is not necessarily enough space in the cities, or close to the coast where a lot of people live and work,” Olaf Waals, project manager and the concept developer, told Digital Trends. “These are also areas that are susceptible to flooding with rising sea levels. We thought it was an interesting idea to look at the technical feasibility of buildin...

It may sound counterintuitive, but Alphabet’s life sciences unit Verily is releasing about 20 million mosquitoes in Fresno, California in order to fight Zika, the mosquito-borne illness. It’s part of Verily’s Debug Project, an initiative announced last October with the mission of reducing “the devastating global health impact that disease-carrying mosquitoes inflict on people around the world.” And now, Verily is launching Debug Fresno, the company’s first field study in the U.S. that will test a mosquito control method that involves sterile insect technique. In essence, the 20 million mosquitoes Verily is releasing are all sterile males that have been treated with  Wolbachia , a naturally occurring bacterium. The test is said to be the largest release of sterile male mosquitoes in the U.S. thus far. Over the next 20 weeks, these bugs will be released in two neighborhoods around 300 acres large. The hope is that when these sterile males ma...
