Science Slices of the Week: Male Contraceptives, Underwater Robots and Sloan Research Fellowships

The Science Slices is a weekly series that expands coverage on Cornell science discoveries, and briefly highlights science news and breakthroughs that have occurred each week. This week, we cover a study on a potential on-demand male contraceptive, findings uncovered about melting rates of Antarctica using an underwater robot, and researchers awarded the 2023 Sloan Research Fellowships.

Using NASA’s James Webb Images Further Explores the Galaxy, from the Planets to Stars

On July 12 NASA revealed stunning first images taken by its James Webb Space Telescope. For scientists, the release of these images will lead to a better understanding of the history and formation of the universe and the potential discovery of life outside of Earth. JWST is aninfrared telescope projected to be the primary observatory for numerous astronomers in the next decade. Unlike the Hubble telescope, JWST can view a larger range of infrared wavelengths, which are longer than visible light wavelengths. As objects farther apart in space emit light with longer wavelengths like infrared, JWST is necessary to observe these objects. 

Prof. Lisa Kaltenegger,astronomy, is the director of the Carl Sagan Institute and explainedthat because JWST is bigger than Hubble, it can collect more light.
