Study challenges assumptions about magnetar formation The study of the magnetar SGR 0501+4516 using Hubble and Gaia telescopes has deepened the mystery of its origins. Previously thought to be associated with the supernova remnant HB9, the magnetar shows no connection to it, which suggests that SGR 0501+4516 may have formed through an alternative process, such […]

Magma chambers influence composition of Mars’ crust A study explores the history of magma chambers on Mars, revealing how these chambers evolve over time. Numerical modelling indicates that early Mars had higher temperatures, allowing upper crustal chambers to last longer, feeding surface eruptions.

Salt may play key role in Martian mudflow formation A study in Communications Earth and Environment suggests that salt could explain how mudflows form on Mars despite the planet’s thin atmosphere. Researchers conducted experiments in Mars-like conditions, finding that salt lowers the freezing point of water, allowing mud to flow longer. Full Story: Eos Underwater […]

Asteroid samples reveal ancient salty incubators Samples from asteroids Ryugu and Bennu have revealed the presence of salts, indicating that salty water environments were common in the early solar system. This finding suggests that such environments could have been incubators for life’s building blocks, a discovery that highlights the potential for organic evolution on asteroids […]

Genetic erosion poses hidden threat to species survival Research on the regent honeyeater, a critically endangered bird from southeastern Australia, reveals that despite severe population decline, the species retains high genetic diversity. Through whole-genome sequencing and ecological modeling, the study underscores the delayed impact of genetic erosion and the importance of integrating genetic data over […]

Geographic split of humans linked to emerging language A genomic analysis suggests that human language ability was present at least 135,000 years ago, coinciding with the first geographic split of Homo sapiens. The research suggests that humans developed the cognitive capacity for complex language before it entered social use. This capacity for symbolic thinking and […]

Rapid crevasse growth on Greenland Ice Sheet Research shows that crevasses on Greenland’s Ice Sheet are growing at an alarming rate, potentially accelerating ice loss and sea level rise. The study, which used advanced digital elevation models to document crevasse volume changes from 2016 to 2021, underscores the need for continued monitoring to refine predictions […]
