In 2015, when NASA's New Horizons spacecraft encountered the Pluto-Charon system, scientists discovered interesting, geologically active objects instead of the inert icy orbs previously envisioned. Scientists have revisited the data to explore the source of cryovolcanic flows and an obvious belt of fractures on Pluto's large moon Charon. These new models suggest that when the moon's internal ocean froze, it may have formed the deep, elongated depressions along its girth but was less likely to lead to cryovolcanoes erupting with ice, water and other materials in its northern hemisphere.
The teeming life in the Southern Ocean, which encircles Antarctica, contributes to brightening the clouds that form there, according to a new study. The clouds are bright because of their high density of water droplets, due in turn to a chain of atmospheric processes that eventually connects back to the Southern Ocean's extraordinary phytoplankton productivity.
Rocks, rain and carbon dioxide help control Earth's climate over thousands of years - like a thermostat - through a process called weathering.
A large study looking at the effects of fertility treatment has found no robust difference in blood pressure, heart rate, lipids, and glucose measurements between children conceived naturally and those conceived using assisted reproductive technologies (ART).
What gives one friend influence over another? Considerable attention has focused on who influences whom; much less is known about why one partner is prone to be influenced by the other. A study tested the hypothesis that within a friend dyad, having fewer friends than one's partner increases susceptibility to influence, because it reduces dissimilarity and promotes compatibility. Results showed that partners with fewer friends were influenced by children with more friends. In each case, the partner with fewer friends became more similar to the partner with more friends. Academic engagement was the only domain where partners with fewer friends also influenced partners with more friends.
In the course of five years, citizens who went on sailing cruises to the Arctic surveyed and collected plastic debris that had washed up on the shores of Svalbard. This has now been analyzed. According to the findings, one third of the plastic debris which still bore imprints or labels allowing an analysis of their origin came from Europe, and much of that number from Germany.
UC Riverside researchers have identified tiny organisms that not only survive but thrive during the first year after a wildfire. The findings could help bring land back to life after fires that are increasing in both size and severity.
A new sodium battery technology shows promise for helping integrate renewable energy into the electric grid. The battery uses Earth-abundant raw materials such as aluminum and sodium.

Historical records of earthquakes in the region go back at least 2,000 years, to a quake in 17 CE that levelled a dozen towns.
As soon as a disaster occurs, satellites are programmed to quickly acquire images over the affected areas.
ChatGPT had been listed as a coauthor of at least four scientific papers by mid-Janaury.
Scientists have discovered a third natural source of quasicrystals, extending the latter’s reputation for violent origins.
Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper shows.
Researchers developed a new approach to building deformable underwater robots, using simple repeating substructures. The team demonstrated the new system in two different example configurations, one like an eel and the other a wing-like hydrofoil.
Young blood may be an elixir for older bodies, rejuvenating aging hearts, muscles, and brains. But how can old blood become young again? Stem cell scientists may have found a way.
New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by environmental factors -- with one exception. Higher temperatures during the height of the growing season were associated with poorer long-term survival among some species, indicating one threat posed by a warming climate.
A new examination of ancient and current species of reptiles conducted by paleobiologists reveals the serious impact of the disappearance of even a few species of reptiles in some island areas. The study has startling conclusions about how, on smaller islands in the Caribbean where human impact was greatest, extinctions have led to the loss of up to two-thirds of the supports for the ecosystem that native reptile species once provided there.
