Figuring out how much energy permeates the center of the Milky Way — a discovery reported in the July 3 edition of the journal Science Advances — could yield new clues to the fundamental source of our galaxy’s power, said L. Matthew Haffner of Embry-Riddle Aeronautical University. The Milky Way’s nucleus thrums with hydrogen that has been ...
Life on Earth would not be possible without the Moon; it keeps our planet’s axis of rotation stable, which controls seasons and regulates our climate. However, there has been considerable debate over how the Moon was formed by studying the Moon’s craters. The popular hypothesis contends that the Moon was formed by a Mars-sized body ...
A new study by University of Alberta physicists provides an explanation for why changes to Earth’s magnetic field over time are weaker over the Pacific region — a mystery scientists have been trying to solve for nearly a century. “This is something that has been a puzzle since the 1930s when it was first noticed,” ...
New Curtin University-led research has uncovered how rocks sourced from the Earth’s mantle are linked to the formation and breakup of supercontinents and super oceans over the past 700 million years, suggesting that the planet is made up of two distinct “faces.” The research, published in the leading journal Nature Geoscience, examined the chemical and ...
Nature is full of colors, from the radiant shine of a peacock’s feathers or the bright warning coloration of toxic frogs to the pearl-white camouflage of polar bears. Except for amber fossils, usually, fine structural detail necessary for the conservation of color is rarely preserved in the fossil record, making most reconstructions of the fossil ...
A subterranean expedition led by Prof. XU Jianchu from the Kunming Institute of Botany of the Chinese Academy of Sciences highlights the importance of understanding the ways in which the relationships between cave organisms and fungi species may have serious ecological and economic implications. The discovery of four novel fungal species growing on bat carcasses ...
Over the course of 182 days, the eROSITA X-ray telescope has completed its first full sweep of the sky that it embarked upon about a year ago. This new map of the hot, energetic universe contains more than 1 million objects, roughly doubling the number of known X-ray sources discovered over the 60-year history of ...
The Jehol Biota is well known for producing exceptionally preserved specimens of feathered dinosaurs, early birds, mammals, as well as insects and early flowering plants. However, the lack of precise age constraints on the early period hinders our understanding of the timing of critical ecological differentiation and radiation, as well as their relationship with ecological ...
Water and its interactions with other substances are essential to human life. However, understanding the structure of the liquid and its hydrogen-bonding networks has been a challenge. According to previous studies, all oxygen atoms in water trimers, tetramers, and pentamers with cyclic minimum-energy structures exist in a two-dimensional (2D) plane. In contrast, the hexamers have ...
Newly released genomic research from Neolithic East Asia has unveiled a missing piece of human prehistory, according to a study conducted by Prof. FU Qiaomei’s team from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences. The study, published in Science, reveals that population movement played a profound role in ...
