FACT-FILLED AND THE MOST HAPPENING CURRENT AFFAIRS FROM AROUND THE WORLD
Robot that can walk and jump on water
Chinese researchers have developed a microbot that can repeatedly jump across the surface of water without tanking. The researchers team from School of Chemical Engineering and Technology was led by Prof. Qinmin Pan. They used a porous, highly repellent nickel foam coating so that the even chargers. Scientists have now FUHaWHG a flHxLEOH EaWWHUy WKaW FaQ EH folded, bent and distorted in a host of different ways. These batteries promise thinner and lighter smartphones, tablets and e-book readers that could be flHxLEOH aQG KROG PRUH FaSaFLWy. YRu could roll up these devices for easy storage in your pocket.
A team of researchers at the Korean Advanced Institute of Science and Technology (KAIST) is behind the QHZ flHxLEOH VROLGVWaWH EaWWHUy.

Microchips to replace humans in drug testing
There have been debates about testing drugs on animals or any other living creature. Well, here comes a solution that will put the problem to an end. Scientists from earvard University aQG DHIHQVH AGvaQFHG 5HVHaUFK PURMHFWV AJHQFy (DA5PA) RI USA KavH developed a microchip that can now be used for such tests. This microchip is a small translucent device, which can be used as a human organ for testing drugs.
According to reports, this single device can bring together ten organchips in order to enable study of the effect of a particular drug on the whole body. Every organ on this microchip LV PaGH uVLQJ FOHaU flHxLEOH SROyPHU. ,W aOVR FRQVLVWV RI KROORZ PLFURfluLG channels that are lined by living human cells. It is these human cells that allow scientists to study the impact of any drug on human organs. Since the device is translucent, it allows researchers to easily view the response of the organs to a drug.
earvard University has successfully designed microchips that mimic lung, heart and intestine.
Digital iris that fools biometric scanners
At the recently held Black eat Security Conference by academics in Spain and the US, a new technique of recreating iris images using the digital codes that are stored in databases and used by iris- recognition systems to identify people was shown. Interestingly, the replica images could even trick the commercially graded iris-recognition systems.
“The idea is to generate the iris image, and once you have the image you can actually print it and show it to the recognition system, and it will say ‘okay, this is the (right) guy,’” says Javier Galbally, who conducted the research with colleagues at the Biometric Recognition Group-ATVS, at the Universidad Autonoma de Madrid, and researchers at West Virginia University.
Earlier, researchers could create wholly synthetic iris images with the characteristics of real iris images. Though the images fooled iris-recognition systems into thinking they were real irises, they were not quite useful in impersonating a real person.
“BuW WKLV LV WKH fiUVW WLPH aQyRQH has essentially reverse- engineered iris codes to create iris images that closely match the eye images of real subjects, creating the possibility of stealing someone’s identity through their iris,” mentions a report by Threat Level.
