The article focuses on the development of paper circuit boards, which are a more environmentally friendly alternative to traditional electronic circuit boards. Topics include the growing problem of electronic waste, the use of paper as a substrate for electronics, and the potential applications of paper circuit boards, such as tracking patient vital signs and revolutionizing shipment tracking.

The article discusses aerodynamics using paper airplanes. Topics discussed include physics and math and engineering research on falling paper according Leif Ristroph, a professor of mathematics at New York University's Courant Institute; experiment to look at the flight of the most rudimentary paper airplanes by Ristroph; and models developed to study aerodynamics.

The article focuses on researchers at the University of Texas at Arlington developing a microbot system for diagnosing bladder diseases more effectively, outlined in a paper titled "A Microbot With an Attached Microforce Sensor for Transurethral Access to the Bladder Interior Wall." It mentions the system, equipped with a microforce sensor and designed to navigate the bladder's interior wall tissue.

The gas turbine machine is one of the major innovations of the 20121 century which has provided society the fastest mode of transportation and one of the cleanest, cost competitive and most thermally efficient means of producing electrical, mechanical, and propulsive power. The development of gas turbines has a long yet phenomenal history of technological advancements and the gas turbine is a unique ever-evolving technology due to multitudes of param eters and technologies influencing its design and performance as comprehensively elaborated in a recently published paper by the author. Gas turbines have become preferred choice due to many advantages offered over other technologies: lowest cost/kW, high power density, high power-to-weight ratio, fuel flexibility, wide ranging applications, and fast- and black-start capabilities. In the ongoing climate change discussion, the gas turbine technology is expected to play an important role in mitigating proper utilization of renewable energy sources and global warming impacts in coming years.

The article informs about presenting a critical challenge to both municipal and institutional menstrual health management. It mentions that the challenge inspired Ajinkya Dhariya, a social entrepreneur in India, to start a sanitary waste management com pany called Pad Care Labs. It further informs that Pad Care is an automated hygiene management system that turns materials used in the production of sanitary pads into plastic pallets which can be reused to produce other products.

The article reports that National Oceanic and Atmospheric Administration and other government agencies are using the Saildrone design for lengthy marine data gathering missions, and one became the first uncrewed vessel to successfully circumnavigate Antarctica. It mentions that Solar panels power scientific instruments and equipment with vessels are monitored on their voyages via satellite, but they operate independently through the course of their travels.

The article focuses on the research paper "Immersion Graded Index Optics: Theory, Design, and Prototypes," by Nina Vaidya, a professor of astronautics, published in June 2022 issue of the journal "Microsystems & Nanoengineering." It describes a pyramidical lens composed of several layers of materials having different refraction indices, designed by Vaidya to deliver sunlight three times more than a solar panel in a day.
