Jupiter hosts more than 100 moons, with most attention focused on the four Galilean moons: Io, Europa, Ganymede and Callisto. This is primarily due to their active geology, including Io being the most volcanically active planetary body in the solar system and Europa having a
Metal-insulator transitions (MITs), in which a material changes from a metallic state with low resistivity to an insulating state because of a change in an external parameter, such as temperature, pressure or an electric field, are a central topic in fundamental physics research.
Scientists have often wondered about species that are unique to Antarctica. But the focus has mainly been on animals, like feathery penguins. CIRES researchers wanted to dig deeper—into the soils—believing tiny organisms could be unique to the continent, too.
Cooling from air conditioning saves lives—more than 5,000 a year in the United States alone—but it also heats up the planet and taxes our electrical grid, scientists say.
While astronomers have found thousands of exoplanets over the last few decades, the true prize continues to elude them—they have yet to find an Earth-mass, rocky planet orbiting in the habitable zone of a sun-like star. That's partially due to cosmic geography—around half of
The question is no longer whether microbial foods can be made. The question now is who can be first to turn them into an industry. KAIST researchers have analyzed the conditions required for the microbial food industry to succeed across manufacturing, markets and regulation,
Despite the importance and dominance of angiosperms ("flowering plants") in the current ecosystem, it is rather surprising that we know so little about their origin and early evolution. Paleobotanists have been making efforts to decipher these enigmas. Unfortunately, their
Fast, on-farm genetic testing for cattle is practical and achievable for northern producers, according to University of Queensland research. In partnership with Meat & Livestock Australia and the Department of Primary Industries, a team from UQ's Queensland Alliance for
Swapping out one letter in a word can entirely change its meaning. Similarly, swapping one atom in a molecule can completely change its identity. A group of chemists at the University of Chicago has demonstrated a new way to make a single-atom edit to a molecule without
How protective is air conditioning in preventing deaths amid soaring temperatures and record heat levels? Yale researchers found that AC use cut the number of annual heat-related deaths by half in the U.S., saving more than 5,000 lives a year. However, while AC is a highly
