Regions like the Antarctic Peninsula and the Thwaites and Pine Island are continuously losing ice due to global warming, Zwally added.

Researchers from the University of Wisconsin-Madison claimed that they have created a phototransistor, which is fastest and most responsive flexible phototransistor till now. According to the researchers, their newest innovation is a huge breakthrough in digital imagining sector.

The most responsive phototransistor was created by Jack Ma, the Lynn H. Matthias Professor, and a fellow researcher, Jung-hun Seo. A phototransistor senses, collects light information and then converts it into an electrical charge. Wavelength of that light and force decides the quality of electrical charge.
