High refractive index polymers (HRIPs) are essential for manufacturing modern optoelectronic devices, including displays and light sensors. However, high-performance HRIPs are expensive and environmentally unfriendly. Recently, a research team from Waseda University developed a new family of HRIPs called poly(thiourea)s. Thanks to unique intermolecular interactions, these compounds can be easily processed into low-cost transparent HRIPs … Read more
Over the course of its elliptical orbit, the moon Enceladus is squeezed unevenly by Saturn’s gravitational pull and deforms from a spherical shape into a football shape and back again. This cyclic stress causes a phenomenon called “tidal heating” within Enceladus and dissipates enough energy to maintain what is believed to be a global ocean … Read more
Microbiology is the branch of biology that explores the world of microscopic organisms, including bacteria, viruses, fungi, protozoa, and algae. These tiny life forms, invisible to the naked eye, play essential roles in ecosystems, human health, agriculture, industry, and environmental processes. Microbiology encompasses diverse areas of study, from microbial diversity and evolution to microbial ecology, … Read more
In most industrial chemical reactions, catalysts combine with the starting materials and accompany them through intermediate stages to the product. In chemistry, this pathway is known as the reaction mechanism, and it is a kind of black box: nobody knows what is happening at the molecular level at first. If the reaction result in the … Read more
In a landmark study based on one of the most comprehensive genomic datasets ever assembled, a team led by scientists at the University of Wisconsin–Madison and Vanderbilt University offer a possible answer to one of the oldest questions about evolution: why some species are generalists and others specialists. Under the guidance of UW–Madison professor of … Read more
