Nov. 11, 2021 Near-Earth Asteroid Might be a Lost Fragment of the Moon The near-Earth asteroid Kamo`oalewa might actually be a fragment of our moon, according to a team of astronomers led by the University of Arizona. Kamo`oalewa is a quasi-satellite – a type of near-Earth asteroid that orbits the sun but remains relatively close to Earth.
Nov. 10, 2021 Global Temperatures Over Last 24,000 Years Show Today's Warming 'Unprecedented' A UArizona-led effort to reconstruct Earth's climate since the last ice age highlights the main drivers of climate change and how far human activity has pushed the climate system.
Nov. 1, 2021 Study Casts Doubt on Theory That Women Aren't as Competitive as Men Women enter competitions at the same rate as men – when they have the option to share their winnings with their peers, new research finds. The study casts doubt on the theory that America's gender wage gap is due to women being less competitive than men.
Nov. 1, 2021 A Life Less Obvious: Study Sheds Light on the Evolution of Underground Microbes A new study sheds light on the evolutionary history of the deep biosphere – a hidden realm of microbes inhabiting the upper few kilometers of Earth's crust.
Oct. 27, 2021 Astronomers Discover Massive Galaxy 'Shipyard' in the Distant Universe Astronomers have discovered a structure thought to be a "protocluster" of galaxies on its way to developing into a galaxy supercluster. The discovery was made possible, in part, by the UArizona-managed Large Binocular Telescope.
Oct. 25, 2021 UArizona-Led Team Finds Nearly 500 Ancient Ceremonial Sites in Southern Mexico Using data from an airborne laser mapping technique called lidar, researchers identified 478 complexes in the Mexican states of Tabasco and Veracruz. The discovery changes researchers' understanding of the relationship between the Olmec civilization and the subsequent Maya civilization.
Oct. 21, 2021 Astronomers Provide 'Field Guide' to Exoplanets Known as Hot Jupiters By combining Hubble Space Telescope observations with theoretical models, a team of astronomers has gained insights into the chemical and physical makeup of a variety of exoplanets known as hot Jupiters.
Oct. 20, 2021 Changing Ocean Currents Are Driving Extreme Winter Weather The U.S. will experience more extreme cold winter weather as climate change slows down ocean currents, new research finds. The study was motivated by the extreme cold experienced in Texas earlier this year.
Oct. 14, 2021 Who's Been Kissing Who? Prairie Dog 'Greet Kisses' Reveal Complex Social Networks Prairie dog kisses helped researcher Jennifer Verdolin map the intricacies of prairie dog social dynamics – from how many friends a particular prairie dog has to how many connections the critter facilitates.
Oct. 12, 2021 Life on LEO: Plants to be Added to the Landscape Evolution Observatory at Biosphere 2 Surprisingly little is known about how rain moves through landscapes once it's on the ground. A $3.5 million grant will allow scientists to study the role of plants and microbes in the process.
