new delvelopment of Cyborg moths
Washington: Remote-controlled moths or ‘biobots’ may be used in future search and rescue operations.  Scientists, including one of Indian-origin, have developed methods for electronically manipulating the flight muscles of moths and for monitoring the electrical signals moths use to control those muscles.

The advance opens the door to the development of remotely-controlled moths, or “biobots” for use in emergency response, researchers said.  “In the big picture, we want to know whether we can control the movement of moths for use in applications such as search and rescue operations,” said Dr Alper Bozkurt, an assistant professor of electrical and computer engineering at North Carolina State University and co-author of the research paper.

“The idea would be to attach sensors to moths in order to create a flexible, aerial sensor network that can identify survivors or public health hazards in the wake of a disaster,” said Bozkurt.

The research presents a technique Bozkurt developed, in conjunction with Dr Amit Lal of Cornell University, for attaching electrodes to a moth during its pupal stage, when the caterpillar is in a cocoon undergoing metamorphosis into its winged adult stage. By attaching electrodes to the muscle groups responsible for a moth’s flight, Bozkurt’s team is able to monitor electromyographic signals - the electric signals the moth uses during flight to tell those muscles what to do.

The moth is connected to a wireless platform that collects the electromyographic data as the moth moves its wings. To give moth freedom to turn left and right, the entire platform levitates, suspended in mid-air by electromagnets.

How we work

Bitcoin is a cryptocurrency, which is a form of electronic cash. This is the first decentralized digital currency: the system was designed to work without a central bank or a single administrator. Many economists and investors consider the Bitcoin market to be a bubble. Bitcoin has also been criticized for its use in illegal transactions, its high power consumption, price instability, and theft from exchanges.

What Is Real Cryptocurrency
Bitcoin is made as a reward for the process known as mining. They can be exchanged for other currencies, products and services. The research produced by Cambridge University estimates that in 2017, there were 2.9 to 5.8 million unique users using cryptocurancency wallet, most of which used bittoine. A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets. Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies.

Bitcoin, created in 2009, was the first decentralized cryptocurrency. Since then, numerous cryptocurrencies have been created. These are frequently called altcoins, as a blend of bitcoin alternative. Bitcoin and its derivatives use decentralized control as opposed to centralized electronic money/central banking systems . The decentralized control is related to the use of bitcoin's blockchain transaction database in the role of a distributed ledger
