WASHINGTON Researchers have developed a new sensor that could allow practical and low-cost detection of low concentrations of methane gas. Measuring methane emissions and leaks is important to a variety of industries because the gas contributes to global warming and air pollution. Agricultural and waste industries emit significant amounts of methane, said Mark Zondlo, leader of the Princeton University research team that developed the sensor. Detecting methane leaks is also critical to the oil and gas industry for both environmental and economic reasons because natural gas is mainly composed of methane.

Researchers create ‘beautiful marriage’ of quantum enemies
Cornell scientists have identified a new contender when it comes to quantum materials for computing and low-temperature electronics.
Using nitride-based materials, the researchers created a material structure that simultaneously exhibits superconductivity – in which electrical resistance vanishes completely – and the quantum Hall effect, which produces resistance with extreme precision when a magnetic field is applied.
“This is a beautiful marriage of the two things we know, at the microscale, that give electrons the most startling quantum properties,” said Debdeep Jena, the David E. Burr Professor of Engineering in the School of Electrical and Computer Engineering and Department of Materials Science and Engineering. Jena led the research, published Feb. 19 in Science Advances, with doctoral student Phillip Dang and research associate Guru Khalsa, the paper’s senior authors.
After graduating from the University of Illinois, Carruthers began working at the US Naval Research Laboratory.
Its telescope and image converter identified molecular hydrogen in space, and its ultraviolet spectrograph was used by the Apollo 16 crew on their flight to the moon.
“In March 1610, Galileo Galilei reported the first use of a telescope to see the mountains and Maria on the moon,” Carruthers wrote in 1972. Many have reported that his project collaborator, Thornton Page, a white man, recognized the ‘outburst of Carruthers and allowed him to lead the project.
After all, just three years earlier, Carruthers had obtained a patent for its revolutionary “Image converter for the detection of electromagnetic radiation, especially in short waves”.

He built his first telescope at the age of 10, and by age 25, George Carruthers earned a Ph.D. in aeronautical and astronautical engineering.
Upon graduating from the University of Illinois, Carruthers started work at the U.S. Naval Research Laboratory.
