Geologists have uncovered strong evidence from Colorado that massive glaciers covered Earth down to the equator hundreds of millions of years ago, transforming the planet into an icicle floating in space.

Like the Earth, the sun likely has swirling polar vortices, according to new research led by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR). But unlike on Earth, the formation and evolution of these vortices are driven by magnetic fields.

Habitat loss and poaching have driven dramatic declines in African elephants, but it is challenging to measure their numbers and monitor changes across the entire continent. A new study has analyzed 53 years of population survey data and found large-scale declines in most populations of both species of African elephants.

Research appearing in Social Psychological and Personality Science identifies a widespread stereotype linking wealth to perceived trustworthiness across diverse cultures.

A new study led by Dr. Jack Tseng, published in PeerJ, has shed light on the intricate relationship between tooth wear and jaw mechanics in highly carnivorous mammals, known as hypercarnivores.

Traditionally, migratory birds are thought to arrive at their wintering grounds after fall migration and remain there until the spring migration back to breeding sites. This assumption forms the basis for determining over-wintering ranges and shaping conservation measures. However, a team led by scientists from the Max Planck Institute of Animal Behavior has discovered that over-wintering ranges may be far more dynamic.

Magnetic reconnection is a fundamental physical process in plasmas, through which the magnetic energy is converted into plasma kinetic energy and thermal energy rapidly. Current sheets in turbulent plasma are the key trigger for magnetic reconnection. However, how current sheets come into being remains unresolved.

Active during the Han Dynasty period in China’s history, Sima Qian is widely considered to be the father of Chinese historiography. A celebrated historian, he is best known for his seminal work, the Shiji, or “Records of the Grand Historian”. Written during the late 2nd century BC, this monumental work stands out as one of the first compiled histories of ancient China, reaching all the way back in time to the mythical “Yellow Emperor”, who reportedly reigned for a hundred years, starting in 2698 BC. Qian Sima was, however, very devoted to his work, and produced one of the foremost historical works from the period. What made his approach to writing history so successful? And what was his legacy for the Chinese people?
